Of course, it is not an easy task to make a huge ship perform a short-distance fold.

There is an essential difference between the folding subspace and the curvature subspace.

For a flying unit to enter the curvature subspace, it must first use a medium engine and curvature space compression technology to continuously accelerate until it breaks through the speed of light.

At the moment of breaking through the speed of light, a mutation will occur at the junction of the instantly formed perfect curvature bubble and the original three-dimensional world.

The vehicle and the curvature bubble will directly enter the curvature subspace.

As long as they can stay above the speed of light, they will not be thrown out.

The folding subspace is different. The folding subspace layer first wraps the matter, but the relative speed of the matter and the original three-dimensional space can be 0.

At the moment when the folding subspace layer is fully formed, it will break through the restrictions of the first cosmic rules, pull itself and the wrapped matter directly into the folding subspace, and appear at another fixed position along the direction of quantum entanglement and the fundamental force tidal oscillation field.

The folding subspace and the curvature subspace can overlap, showing that the nature of folding is more basic.

Humans have not yet mastered the core principle of folding, but have taken a shortcut using the core of the Mi tribe to realize its application.

This principle is just like when humans first invented gunpowder, they knew that mixing saltpeter, sulfur and charcoal in proportion could produce explosive powder.

Why can it explode?

That's not important.

Just explode and it's done.

It took humans many years to figure out the ratio of one sulfur, one charcoal and three saltpeter, countless trials and errors, and then got closer and closer.

Now Fredes uses the core of the Mi tribe through huge calculations. Without understanding the principle, he forcibly calculates the most reasonable match, finds the most perfect folding energy output curve, and builds a sufficiently stable large folding subspace layer around the bullet-shaped Morning Breeze II, which is ten kilometers long.

This is the ultimate manifestation of applied science completely overwhelming basic theoretical science, and there is no essential difference from the use of gunpowder in human research.

The advantage is that this allows humans to gain some convenience in advance when their understanding of the universe is not deep enough.

The disadvantage is that humans must face risks when they control technology that should not belong to them, just like the frequent gunpowder explosions in those years.

Under normal circumstances, the smaller core of the Mi Clan can only carry a small mass unit to complete the folding.

The Shadow Science Academy led by Xiaofu and Ou Qinglan applied the principle of the stargate folding to the ship, using the supermassive black hole that the shadow galaxy revolves around as a fulcrum, and found a particularly strong network of gravitational lines in the universe. The

supermassive black hole that sucks the shadow galaxy is like a whirlpool in the center of a lake in the universe.

The huge gravitational field swirls around the black hole in three-dimensional space and spreads in all directions.

One of the curved gravitational lines originates from the edge of the black hole and then spreads out, which just happens to be the propulsion line of Morning Breeze II.

Morning Breeze 2 will use the more stable curvature metaspace structure provided by this gravitational line, like being mounted on a folding sling, to slingshot forward every once in a while.

This is the core principle of the short-range folding of Morning Breeze 2.

This gravitational line itself is curved, but after distorting the space, it is equivalent to a straight line in the original three-dimensional space.

And this gravitational line just overlaps with the second orbit of the shadow galaxy around the black hole.

According to Xiaofu's calculation, assuming that more than six months later, when Morning Breeze 2 enters the orbit of the second shadow galaxy, the distance between the shadow of the sun and Morning Breeze 2 will be within 1 billion kilometers.

At this time, Morning Breeze 2 can use the close-range gravitational pull of the shadow of the sun to jump out of the gravitational line of the black hole, instantly arrive near the shadow galaxy, and stop.

During the entire process, Morning Breeze II needs to perform more than 6,400 folds, and each time it needs to construct a perfect folded subspace membrane.

When leaving the folded space, it needs to perfectly match the external curvature subspace.

When it finally arrives, it needs to accurately capture the gravitational field of the shadow sun, escape the attraction of the black hole's gravitational lines, and complete a rapid turn, otherwise it will directly "jump" into the black hole.

In short, allowing Morning Breeze II to fold and launch is a comprehensive solution that uses curvature, folding, and unified force to the extreme. Each step requires an extremely large amount of computing, and there can be no mistakes.

One mistake means death.

"Xiaofu, I understand what you mean. There are still risks, right?"

Fredes scooped up a spoonful of caviar, and then took a particularly generous gulp of vodka. "Yes, the failure rate is about 48.99%, which is higher than I expected. But I didn't discuss it with you in advance, because I know that with your personality..." Chen Feng

laughed, "It will definitely be risky, right?"

"Yes."

Chen Feng patted Fredes on the shoulder, "Xiaofu is the one who knows me. Very good, if you are late, it's better not to come. Then I will go to the class, Xiaofu, you should also pay more attention to rest."

"Okay, brother."

Chen Feng gave the soldiers a real combat exercise on the first day of training, and basically achieved the goal.

In the following days, he learned his lesson and no longer went on the field himself, but just served as an instructor honestly.

The warriors learned the basic and advanced tutorials very quickly, and the advanced textbooks were not too difficult, but in the final master-level textbook, when Chen Feng hoped that others would also learn the same level of battlefield intuition as himself, he stumped them.

The trainees seemed to be struggling and making slow progress.

It was the battlefield intuition that determined that Chen Feng could stand firm in the wheeled battle of a hundred people with the same level of equipment despite the dangers.

Obviously, Chen Feng's extraordinary intuitive reaction is the core quality that really makes him stand out.

He never cherishes his own skills, and he is not afraid of being surpassed by others, so he sincerely hopes that others can learn all his skills.

There are difficulties this time, but at least he sees hope.

In the previous timeline, people were trapped in the "Warrior Plan" and "Thinking Coil" that enveloped the entire society. They pursued absolute rationality in everything, and had to find a reasonable fulcrum for everything in pursuit of a low error rate.

This looks good.

The advantage is that this makes the warriors' lower level extremely high, but the disadvantage is that they lack creativity. The warriors' thinking patterns when using equipment are confined to the old rules and it is difficult to break through the upper limit.

This time there was originally the same problem, or even more serious.

But in the Hundred Years War, the returning warriors went out again and again, and experienced life and death again and again.

These experiences on the border of life and death allowed the returning warriors to constantly break through their own bottlenecks, gradually break the blockade of thinking, and constantly refresh their upper limits.

These warriors have more battlefield experience than Chen Feng.

Assuming that Chen Feng is now at the tenth level, while the warriors in the previous timeline are only at the first level, the realm of the returning warriors in this timeline has generally reached above the fifth level, and some have even reached the seventh, eighth, or even ninth level.

This is why the trial warriors that Chen Feng encountered were relatively strong and almost caused him to flip.

At the same time, Chen Feng also firmly believed that if the warriors started from the fifth level and moved up a little bit, the hope of reaching the tenth level would be countless times greater than before.

In order to advance his teaching plan, Chen Feng selected a team of assistants from the warriors to help him control the details, assist in adjustments, and improve the teaching materials, while constantly providing Fanxing with new and more accurate evaluation parameters.

It's fun to say.

Ding Hu, who had the lowest rank and the weakest strength among all the soldiers participating in the training, became Chen Feng's first assistant.

Most people also didn't understand why Chen Feng would appoint a "old bastard" lieutenant who had been in the Shadow of the Earth for hundreds of years as the first assistant.

Even the Academy of Sages, which was basically aware of the situation, raised objections, believing that Chen Feng's forced promotion of Ding Hu was a bit of nepotism.

Ding Hu himself didn't understand it either.

He wanted to ask Chen Feng why it was me, but in the end he didn't dare to ask, but just bit the bullet and took the position.

On the first day, Ding Hu was trembling with fear, daring not to give instructions or criticize, but just honestly acted as a mouthpiece, seizing the time to strengthen his studies and trying to absorb and digest.

On the second day, Brother Hu changed under heavy pressure.

Although he himself was unable to complete the high-intensity operations performed by senior fighters due to his long absence from the battlefield, it did not prevent him from beginning to understand the problems in other people's operations.

For example, when moving, the engine power was increased by 2%, resulting in an error of 0.05 seconds in the landing time from movement to stillness.

For example, when completing the concentrated fire according to the instructions, how many degrees should the incident angle be switched, and how much higher or lower the power of the energy weapon can better respond to and resonate with the attacks of others.

Or in some environments that require quick decision-making, where is the room for improvement in the intuitive judgments made subconsciously by the fighters.

At what level, what kind of simulation environment should be chosen for intensive training.

Ding Hu has some opinions on the daily training content of most people.

But at this time he still lacked confidence, and every time he asked a question, he would consult Chen Feng.

Ding Hu was initially worried that he would disturb the sage.

The other party would be impatient.

He did not expect that Chen Feng would show great enthusiasm in instructing him, and he would tell him everything he knew. After each question, the sage would ask one more question, "Brother Hu, did you understand? If you have any questions, feel free to ask."

The sage was very gentle and enthusiastic, which was completely different from the fierceness and toughness he showed when teaching others in actual combat.

Brother Hu was both moved and terrified, and he wished to die for him.

That’s not all. When the tutorial ended that day, Chen Feng called Ding Hu and said, “Brother Hu, you did very well today and made rapid progress. The problems and improvement plans you picked out have an accuracy rate of over 50%. When your judgment accuracy rate reaches 100%, I can confidently hand over all the teaching tasks to you. Believe in yourself, you have the potential to become the world’s number one instructor. Come on!”

It is said that crying was heard in Ding Hu’s dormitory that night, and he also said some strange words like “What virtue do I have?” and “I will not let down the trust of the sages.”

Ding Hu’s life was very smooth in the first half.

He joined the army at a young age and ranked among the top in internal competitions many times. In less than 20 years, he climbed from a private to the rank of lieutenant, and was seconded to the Great Snow Mountain Base, which had trained countless elites. At the same time, he also took over the important task of the instructor of the "Sage Reserve" class, which was highly expected.

At that time, Ding Hu led seven or eight recruit classes, and one of the classes was full of Chen Feng XX.

In addition to their similar appearance to the sages, these members also had outstanding basic qualities.

At that time, Ding Hu was full of ambition and vowed to train his trainees into talents.

As time passed, he basically achieved his ambition.

One after another, "Chen Feng" and other trainees graduated from his recruit class and went to the battlefield.

Some never return, while others rise to higher positions.

Among Ding Hu's students, the one with the highest rank is Bond, who was promoted to major general for his military exploits.

Before Bond, there was a young genius named Chen Feng 1987, who was known for his command and combat prowess. Before his death in battle, he had become a lieutenant general in charge of a large fleet at the age of less than 50.

Although Chen Feng 1987 repeatedly denied it, many people still firmly believed that he was the reincarnation of the ancient philosopher.

Ding Hu almost thought so.

That period was the proudest few years in Ding Hu's life. When he talked to people, his nose was a little upturned.

He didn't understand why his career path seemed to be paused when he reached the level of the second-level instructor in the Snow Mountain.

Like other instructors, if they trained a general-level student, they would at least be promoted to major.

But he was stuck in the Snow Mountain and couldn't move, feeling very depressed and frustrated.

He submitted promotion reports to himself again and again, and even dared to slam the table at the command headquarters.

His reports were rejected again and again.

Later, he simply asked to join the external battlefield as a recruit, but was still rejected.

Although he never complained, he must have felt disappointed in his heart.

But about thirty-six years ago, in 1987, Chen Feng died in the battle of Sirius Binary Stars, and all unrealistic dreams were shattered.

People's expectations were dashed.

Ding Hu was devastated and no longer ran to the command center, no longer wanted to be promoted, and was even more dissatisfied with his determination to run away.

He seemed to have accepted his fate, and was content to be an ordinary instructor in the Great Snow Mountain, and was mentally prepared to wait for the final battle with others in the Shadow Galaxy.

Now, as someone who has taught countless "Chen Fengs", Ding Hu finally waited for the sage himself.

Before being asked to meet Chen Feng, he didn't know how special he was.

Now he understands how much hope Chen Feng has for him.

The first instructor of mankind.

These six simple words carry immeasurable weight.

Ding Hu secretly made up his mind to make himself worthy of the praise of the sage.

On the third day, his judgment accuracy reached 60%.

On the fourth day, 70%.

On the fifth day, 80%.

On the sixth day, 90%.

On the seventh day, 100%.

Some people who were originally dissatisfied with Ding Hu, including the shadow force warriors, gradually became convinced.

Everyone's talents are really different.

Some people are born to be good at charging and breaking into formations, while others can see through the imperfections of others at a glance and are born to be instructors.

In terms of contribution, there is no difference between the two.

Ding Hu might be a hindrance on the battlefield, but with his help, even if others can only exert 1% more of their potential, he has made outstanding contributions.

Since then, Chen Feng officially promoted Ding Hu to the chief assistant instructor, no longer personally involved in the teaching content, but only looked at the training report outlines provided by Ding Hu every day.

Ding Hu's achievements over the past years have finally been fully recognized, and combined with his current work, his military rank has also risen sharply on the spot and he has become a lieutenant general.

When the handover was officially confirmed, Chen Feng patted Ding Hu on the shoulder and said, "Brother Hu, you see, I told you that you can do it."

Ding Hu beat his chest and swore, "That's because you, the sage, taught me well. If you say I can do it, I can do it!"

Chen Feng smiled, "Okay, get to work."

Chen Feng withdrew from the virtual space and opened a new cosmology textbook.

Before reading the book, he curled his lips and smiled, secretly feeling a little amused. Before he

started to pull Brother Hu up, Chen Feng actually didn't expect him to really take over his clothes and take over the entire teaching plan.

Chen Feng just wanted to be lazy and then give it a try with the idea of ​​trying his best.

After all, he couldn't just focus on being an instructor. He still had to read books and couldn't be illiterate anymore.

Chen Feng did not deny that he had the intention of deliberately tormenting Brother Hu.

Brother Hu had been the number one instructor in two timelines. This time, he had been cheated by the Academy of Sages for most of his life, and his potential had not been fully utilized. It was better to let Brother Hu "do more work for the capable."

As a result, Ding Hu really used seven days to return himself a perfect instructor.

Chen Feng was shocked.

It really is true that the courage of a person determines the yield of the land.

Is this the power of faith?

God said to a person, you can do it.

And then this person really can do it.

After the noise, there was tranquility. After teaching most of the teaching work to Ding Hu, Chen Feng's daily life became much simpler.

Get up on time every day, first spend two hours to complete a full set of physical training, and then spend another two hours in the simulated space to operate the Star Shadow Armor for a high-intensity confrontation training.

After lunch at noon, take a short nap, start reading in the afternoon, continue to study cosmology-related knowledge in depth, and chat with Xiao Fu for a while during dinner.

After dinner, Chen Feng will connect to the Shadow Galaxy again, take a look at the battle report outside, and then play a few games with Tang Tianxin.

Unknowingly, in such a peaceful life, two months have passed.

After dinner that day, Chen Feng did not play chess with Tang Tianxin, but attended a high-level meeting.

The core of the meeting was the analysis of the new battle situation.

In these two months, the situation outside has changed dramatically, changing several times a day.

All the baits laid by humans in the Orion Arm were peeled off layer by layer by the compound eyes like peeling onions.

The Orton Galaxy and the Xuanwu Galaxy were successively breached.

Just three hours before the meeting, the DF-711 Fortress Starship was finally breached.

From then on, the core strength of mankind was only the last shadow galaxy.

Lu Xianfeng first clicked on a video projection.

In the video, the once noisy DF-711 galaxy returned to a dead silence, leaving only the desolate and ruined battlefield ruins.

In this space, countless human or compound eye debris are floating around, and from time to time there is a glimmer of high-energy reaction, but there is no trace of human activity.

A super-small star floats there quietly, releasing a dim glow to the outside, and is occasionally ignited by metal fragments that collide with it, reflecting black spots.

More debris surrounding the star's gravitational field sometimes gathers, or quietly moves in direction, as if to become the fragmented asteroid belt of Star 001.

Star 001 will absorb more and more debris over a period of time ranging from 100,000 years to tens of thousands of years, and its mass will gradually increase, and finally collapse into a small neutron star.

The prism array of the compound eyes finally completed the encirclement. Although it failed to completely decompose the fortress ship, it tore it into countless pieces and allowed the "captured" 001 star to see the light of day again.

001 gained "freedom", but became a "dead object" in the universe and was destined to die quickly.

Suddenly, the video stopped abruptly.

Lu Xianfeng introduced: "This is the last piece of information sent back by our last artificial intelligence detector. A total of 7,134,621,117 people in the DF-711 Fortress Starship have died. A moment of silence."

...

"The moment of silence is over."

Ou Qinglan stood up, first glanced at Chen Feng who was sitting at the head, and then briefly introduced the important information that the compatriots in the Fortress Starship exchanged for their lives.

Through years of attempts and the extreme pressure of stars in the face-to-face battle with the Compound Eye Fleet in the past few months, the scientific researchers in the DF-711 Fortress Ship have summarized a complete set of rapid development systems for stellar energy.

The development of stellar energy is different from fossil energy and pure light energy absorption. Every extraction of stellar energy may lead to a violent reaction.

Once the intensity of the reaction exceeds the limit, it may trigger a chain reaction in the star, leading to an uncontrollable disaster.

To control the direct development of stars to a level that is both strong enough and safe enough requires a huge scientific system and long-term experience accumulation.

In addition to the direct confrontation with the wing ship, the DF-711 fortress starship's development system for the 001 star is the real core achievement.

"We have just completed the rapid absorption. This is the Academy of Sciences' deep star development plan. We plan to use the remaining two months to build the shadow sun development system as quickly as possible. Please take a look."

Chen Feng took a quick look. He didn't understand the specific details, but the conclusion was very straightforward.

Once the rapid development plan is successful, the remaining life of the shadow sun will be rapidly shortened from about 5 billion years to 5,000 years, and the energy release rate will be accelerated by a million times.

According to the analysis results, if humans can master this technology 500 years in advance, humans will be able to quickly explode productivity in some planetary systems, and the current human military scale can be expanded at least ten times.

This is a good technology, but it's a pity that it came too late.

Chen Feng raised an objection, "I looked at the current energy reserves in the Shadow Galaxy. Aren't there still a huge amount of bio-batteries available? There is no need to directly squeeze the Shadow Sun to obtain more energy, right?"

Ou Qinglan shook his head and said, "The composition of the Shadow Sun is exactly the same as the Sun, but it is very different from Star 001. The Shadow Sun, Star 001, and even almost every star in the Orion Arm are different. There should be different development rules for different stars. We have already After verifying a type of planet in the Fortress Starship, if there is enough time, we would of course like to verify it again in the Shadow Galaxy, so that we can summarize a more universal law. Sir, you can write it down and take it back, even if we lose this time. In your next timeline, you can also get the benefits of this technology. "

Chen Feng was stunned, "Is that so?"

The war has not yet started, and Ou Qinglan and others have already begun to prepare for the people in the next timeline.

This is exactly in line with Lin Bu's criticism of Chen Feng, so that he didn't know how to answer.

He said calmly: "That's fine, you can decide for yourselves."

The meeting continued.

Chen Feng stopped speaking and listened quietly.

The commanders on the Shadow side changed their combat ideas.

Before Chen Feng appeared, their main strategy was to kill the ridge ships as quickly as possible.

Now the strategy has changed, and it has become a strict defense, waiting for Chen Feng to arrive with the core of the Mystery Tribe.

The first line of defense will be built outside the ten-layer Dyson membrane, mainly with a fortress chain array similar to the Basalt Galaxy.

The second line of defense will be arranged around the asteroid belt.

Humans will deploy a large number of highly mobile troops in the asteroid belt, and use asteroids as natural cover to hide some land-based cannons and force field tearing generators.

The third line of defense is located outside the orbit of the Earth's shadow and inside the orbit of Mars.

Humans have deployed a total of 64 spherical war fortresses, each with a diameter of 3,000 kilometers, between the Earth and the shadow of Mars.

These 64 fortresses revolve around the shadow of the sun, with their orbits staggered and in a delicate relative balance, forming a structure similar to C60 ethylene. The fourth

front is the former "shadow of Mercury", now a polyhedral prismatic battleship with a diameter of 4,878 kilometers.

Almost 90% of the scientific research power and administrative resources are concentrated in this huge prismatic battleship.

As for the leadership of the military system, it is distributed among the major fleets.

Chen Feng had nothing to say about the battle arrangements. Even if he said anything, it would only make matters worse. He just nodded without commenting.

Time flew by, and more than two months had passed in the blink of an eye.

With the first space mine being triggered, the first batch of 30,000 compound eye edge ships arrived at the periphery of the Shadow Galaxy.

The defense of the last prosperous galaxy of mankind has officially begun.

Chen Feng could not participate in the war, but 14,000 of his 50,000 students went.

14,000 of the latest Star Shadow armors, which contained all the cutting-edge technology and all the rare materials of the huge Morning Wind Empire, but did not have the ability to fold, turned into a steel torrent on the battlefield.

Torrent Commando was the name this group of people gave themselves.

Chen Feng's students began to demonstrate their military power, shining the last brilliant rays of humanity.
