Chapter 707 Returning Home
King Insect Lu submitted some photos and videos.
The yellow sand barrier is a relatively basic and low-cost means of protection, composed of some low-level carvings. A second-level civilization can use this method.
Lu Yuan breathed a sigh of relief and looked at the photo carefully. This settlement was quite large, covering a full 20,000 square kilometers. Theoretically, a city in the sky could not occupy such a large area.
"Wang, according to our reconnaissance, in addition to the yellow sand barrier, there may also be optical stealth."
This is a method of achieving optical invisibility through the distortion of light, which is already within the realm of third-level civilization!
"How did you determine that the Human Alliance was in this settlement?"
"It's very simple. I smelled it! Such a large settlement community requires a lot of water resources. We smelled traces of life below the river." King Insect Lu Da twitched his nose. "I can guarantee that there is a human community living in it. There is a high probability that they are the ones you are looking for."
Lu Yuan nodded. These insects were becoming smarter and smarter, and they really lived up to his training.
"There are also smells of other species in the river, like pigs, cows, and sheep. There are also smells similar to the minotaurs of the Taurus civilization, and there are also smells similar to octopus people. I estimate that there are five civilizations gathered in that place."
"It would be difficult to investigate if we had more information. After all, you instructed us not to rashly cause a conflict."
Lu Yuan was in a good mood. "Thank you for your hard work. We will set off immediately after we prepare the logistics! Zerg warriors are also the foundation of our Green City. You should also select some people to go over. The smaller ones cannot exceed 10 meters in length."
"Yes!" The king insects saluted respectfully and prepared to go with great interest.
In their minds, human mother civilization is equivalent to Princess Green’s in-laws’ family!
And their Zerg Legion is equivalent to Princess Green’s mother’s home!
The relationship between the two sides is still very delicate.
Just like that, a week later, all the logistical work was completed, and Lu Yuan also sensed through his dreams that the general location was indeed there...
He even mentioned a few words in his dream: "If we can send a spacecraft to your side, would you welcome a diplomatic visit from Green City?"
On the Human Alliance side, Li Jun and others responded normally: "That's great, our development is also very rapid, it will definitely surprise you!"
Since the other party said so, Lu Yuan prepared to give them a big surprise.
"Everyone, please check your carry-on luggage and board the spacecraft in an orderly manner."
The diplomats landed on the "Green Knight" in a mighty procession. The spacecraft was spacious and majestic, with a streamlined main body covered with silver-white composite armor. The surface was covered with honeycomb-shaped heat dissipation patterns, and it glowed faintly under the sunlight.
The bow of the ship is as sharp as a sword, with six groups of ion thruster arrays symmetrically distributed on both sides, which are intermittently spitting out light blue tail flames.
The interior of the ship is the famous "Heaven in the Pot", with a total area of one million cubic meters. Everyone can be arranged with a decent medium-sized room and there is no need to live in a multi-person dormitory.
Lu Yuan put down his suitcase. The room was equipped with a TV, computer, kettle, refrigerator, sweeping robot and all kinds of furniture. There were also some "grass" planted in the corner to purify the air.
"The living conditions these days...are worthy of the cost of 1,000 spiritual charms." Lu Yuan sighed in his heart.
How much is 1,000 spiritual charm worth? Even if a third-level civilization does not eat or drink, it will take three to five years to accumulate it!
I took Miss Conch to visit this big spaceship and met many old acquaintances along the way.
Professor Lu Tiantian, a biological expert and mythology blood expert, teased, "You two are truly the model representatives of the era of the great disintegration of marriage. You are stuck together all day long."
"Alas, it's a pity that I'm so old and still haven't found my soul mate."
Lu Yuan smiled and said, "If that doesn't work, why don't you go to the Human Alliance and find one?"
"But the idea of a 'soulmate' is also a fallacy. People are always isolated islands from each other. In addition, humans are hormone-driven animals, so they have to maintain a good image in order to attract a partner for a long time."
"Haha, that's true. As long as you have a good image, even an uncle can attract girls." Lu Tiantian lifted his white hair. His hair was gray, but his appearance was not bad.
After greeting these familiar people, Lu Yuan visited the Zerg warriors, who occupied a dozen large rooms in the Huzhong Cave Heaven. There were a total of one hundred high-level Zerg people, who were considered the guard team of the conch.
They were actually quite curious about the spaceship. They looked around here and there. Some of them were even playing on the computer. They stood up and greeted Lu Yuan only after seeing him.
"You guys play your own games!"
I took the girl for a stroll and finally arrived at the sightseeing hall.
In the visitor area, there is a semi-elliptical transparent acrylic shield, through which you can see the prosperous Green City. Countless people are offering their blessings to the mother civilization in the big square.
Reporters were also taking pictures. This trip will be open and transparent. After all, most citizens are very concerned about it.
Nine o'clock in the morning.
"Ding Dong! The Green Knight is about to depart. Please put away your carry-on luggage. The restaurant will provide dining from 11:00 to 14:00 and 16:00 to 19:00."
"boom!"
The hull trembled slightly, and driven by the nuclear fusion engine, the plasma light became brighter and brighter.
The drifting glyph began to flicker, and the spacecraft left wave-like scratches in the air, and its speed continued to increase.
Twelve hours later, the Green Knight arrived at the location of the space tunnel.
At an altitude of 30,000 meters, there was a large aerospace fortress called "Shield of the Sky", like a giant suspended steel city.
Big, really big!
A conservative estimate is 3,000 square kilometers!
The outermost layer of the fortress is a rotating defense ring, which is densely covered with turret arrays, like an indestructible metal wall.
Inside the ring, there is a "strange light ball" similar to a wormhole, which is the entrance to the space tunnel.
The edge of the entrance was not a smooth circle, but twisted and fluctuating, like a vortex stirred by an invisible hand. The cave entrance was glowing with a faint blue-purple light, and occasionally a few golden energy arcs burst out, flashing briefly in the void like lightning, and then quickly annihilated.
It is not easy to open a stable entrance and exit in the space tunnel.
"Is this fortress the highest combat power of the Buzhou Alliance?" Lu Yuan asked.
"Yes, it is considered the lowest level fifth civilization building." An expert proudly introduced, "The construction cost is 1,200 civilization points of materials and 800,000 spiritual charms..."
Lu Yuan couldn't help but be amazed. Only the Buzhou Alliance could afford such an expensive thing.
Humans alone...may need another 1,000 or 2,000 years to develop - well, this is the normal development time first.
On one side of the "Sky Shield", various large and small spaceships are lined up.
On the other side, various spaceships emerged from the space tunnel.
They were transmitted from afar, either loaded with goods or carrying people, rushing to various places in the ruins of Buzhou.
There are also some spaceships that are drilling in.
The team of "Green Knight" took about an hour to finally reach the "Sky Shield" aerospace fortress and moved forward along the indicator light.
Lu Yuan saw an entrance that looked like ripples on water.
"After entering the space tunnel, the intelligent life on the entire spacecraft cannot feel the passage of time, as if they arrived at the destination in the blink of an eye." The professor introduced again.
"But for outside observers, even if they travel through a space tunnel, it still takes some time. Our current estimate is that this kind of travel can reach about 0.5 times the speed of light. Theoretically, it can exceed the speed of light, just like a wormhole. However, the quality of this tunnel is not good enough, so the maximum speed is only 0.5 times the speed of light."
"Isn't it because of the effect of relativity that we can't feel the passage of time?" Lu Yuan asked casually.
"Of course not. 0.5c is not enough to cause a serious clock slowing effect. It is a certain property of the space tunnel."
"We're about to go in, see you in a second."
The spacecraft entered the "water ripples". At that moment, the sky and the earth seemed pure white.
Everyone fell into a state of motionlessness, in the high-dimensional space and time, time became blurred.
Three-dimensional matter cannot even move in higher-dimensional space-time.
Only Lu Yuan was strolling leisurely in this pure white space.
He possesses the eyeball of [Monster Mythology], which is a top-level spatial ability. Even if the matter on his body is frozen, his soul can still think.
"So that's it. It's not that space-time no longer exists, but that in high-dimensional space-time, physical parameters such as speed and distance are all different from those in three-dimensional space-time."
To give a simple example, the physical parameter "distance" can be determined by only two coordinates (x, y) in two-dimensional space, but requires three coordinates (x, y, z) in three-dimensional space.
Today's high-dimensional space-time requires more parameters.
The matter in three-dimensional space does not match the physics here, so it looks like it is frozen.
Lu Yuan studied it carefully for a while and found that he was just looking at the moon in the water and flowers in the fog, so he did not study it any further.
"After all, the technology of a Level 5 civilization requires a large group of people to complete. It's simply unrealistic for me to want to understand everything by myself."
However, he discovered that the space tunnel was actually quite fragile, just like forcibly digging a tiny tunnel in a pile of sand. As long as the sand moved slightly, the tunnel would collapse.
With the ability of [Monster Mythology], it can be easily overturned... Of course, he can't do that.
"You don't even think of a way to reinforce the tunnel. Alas, if you don't know the principle and forcefully develop cutting-edge technology, you will indeed end up in a predicament like this."
However, the fluidity of the space is not very high. Lu Yuan estimated that as long as it is maintained in time, it can last for a long time.
He suddenly had an idea: "Wait, that's why! I was wondering why the Emperor of Heaven wanted to build a [Immortal Palace], since the space tunnel can also be used for teleportation. The more important purpose of the [Immortal Palace] is to maintain the stability of the tunnel and reduce maintenance costs."
Don't underestimate the value of the four words "reduce costs".
Regardless of whether it is a level six civilization or a level seven civilization, any ruler has to worry about funding issues.
There is only one reason for the collapse of a dynasty - there is no money in the treasury.
"If I dig a space tunnel myself and teleport Yunhai City to the North, what should I do?"
Lu Yuan observed for a while and soon mastered the method. The tentacles of [Monster Myth] actually have the ability to dig. When the time comes, he can use the Greedy Demon to grow a tentacle and start digging.
"It's more economical to dig a tunnel that could collapse at any time. A mid-level tunnel like the Buzhou Alliance is a bit expensive... There's no need for me to dig a high-level one by myself, so I'll just do a simple one."
…
As I was thinking, the sky and the earth changed from milky white to colorful, and some mysterious idealistic light from the outside world shone into this high-dimensional space.
The spaceship was pulled and leaped out of the space with a "whoosh".
We have arrived at the destination of this trip, the Kusi Desert.
The surrounding air is very hot, with the temperature at 60 degrees Celsius all year round. The air in the desert is like a steamer.
However, the spacecraft did have comfortable air conditioning, and everyone was in high spirits.
King Insect Lu Da was invited to the cockpit and was responsible for giving directions: "It's still 500,000 kilometers from here. Everyone will have to wait for a while."
Five hundred thousand kilometers... Actually, it’s quite far.
A circle around the earth's equator is only 40,000 kilometers.
Along the way, Lu Yuan saw quite a number of unmanned mining devices operating deep underground.
These robots belong to different civilizations, and how much minerals they can dig depends on their own abilities.
Professor Sha Mo, who is responsible for this aspect, acts as the commentator.
"If you want to mine here, you must first bid for prospecting rights and obtain an exploration license. No second prospecting rights are allowed within the approved block scope and period, and no other civilization is allowed to explore for mineral resources in the block, which can reduce conflicts between civilizations."
"The Alliance will collect taxes on the mined minerals, but the tax is not high, 11%."
As a first generation person, Shamo is still active in the workplace. He is truly getting stronger with age.
"Civilizations will not tear each other apart over such a small tax. Everyone wants a peaceful development environment."
"Our Green City mining area is 30,000 kilometers away from here... It produces some inferior minerals, such as red gold sand, black jade, etc. Alas, it doesn't feel very good. I have to find a way to bid for another piece of land in the future."
"It's better to have something than nothing." Lu Yuan smiled.
These are all primary carving and seal engraving materials, which are in great demand and can only be regenerated with the change of eras. Even if they are of inferior quality, humans still need them in large quantities.
This desert is too large and its surface is covered with thick yellow sand, which makes surveying difficult. Every bid involves an element of luck.
If he uses the spatial ability of [Monster Myth] to survey, there will be a chance to find something. Lu Yuan plans to observe all the way and tell Old Cat directly if he finds something good.
Just like that, the spacecraft officially entered the cruising state. Compared with the majestic Pangu Continent, the flying speed of hundreds of kilometers per hour was still a little slow.
We walked along the edge of the Kusi Desert and it took more than forty days to reach the destination described by the Zerg Legion.
In order to observe the mineral-rich areas, Lu Yuan looked so hard that he felt dizzy, but he managed to pick out dozens of areas that might have high-density extraordinary minerals.
After sending the information to Lao Mao, the guy really shouted excitedly on the screen: "Why didn't you say so earlier!"
Lu Yuan: ...
Don't you know I was still asleep at that time?
He was a little nervous. He rubbed his sore eyes and leaned against the glass window to look into the distance.
This is an arid plain with rugged rocks and cracked ground. Occasionally, you can see sparse drought-resistant plants and small animals in caves.
A cloud of black smoke rose from the distance, it was the thick smoke from the volcano.
The annual temperature is 30-40 degrees Celsius, which is not as hot as the desert, but at least it can accommodate life.
"Commander-in-chief, we are about 500 kilometers away from that civilized settlement. We can't get any closer. Do you need to send a drone to say hello?"
The current captain of the Green Knight is Rear Admiral Lu Ying, the treasure hunter. "According to the unspoken rules of Pangu Continent, a safe distance of 500 kilometers between technological civilizations is a more appropriate distance."
"There are multiple civilizations gathered there. Do we need to adopt more covert means of contact?"
Lu Yuan's heart was becoming more and more excited. He had imagined the scene of returning home in glory... Well, now that he had achieved something, he should be able to bring honor to his family, right?
When this moment really happened, I felt like I had just woken up from a dream, as if everything was just a dream.
No, this is not a dream!
The people around me, the spaceship, and the power I possess, are all obtained step by step, down to earth!
Lu Yuan took a deep breath: "Green Knight enters stealth mode, releases drones for reconnaissance, and does not conflict with those civilizations. I... will contact them!"
At this time, all the passengers in the cabin were excited and expectant with a hint of nervousness.
The spacecraft's cloaking glyph is activated, making it almost optically invisible.
Several drones simulating eagles flew towards their destination.
Lu Yuan entered a dream state and informed the other party of the news through the "Twin Wutong Trees" that he controlled.
There is always someone on duty in the Sycamore Tree Dream.
The sudden appearance of this news shocked the staff in Yunhai City!
"Why didn't you tell me earlier?" Li Jun, the colonel of Yunhai City, rubbed his hands, his face flushed red, and he looked extremely excited, "We weren't even prepared!!"
"Haha, this is great. After so many years...really...so many years, I finally waited for this day!"
"If you had told me earlier, there wouldn't be such a surprise." Lu Yuan laughed, "You guys should not make a big fuss. After all, this is just our first visit, and many things are still a little vague. It's better to give each other some space."
"Do you need me to notify your family to come online?"
"No need, let's just meet in real life." Lu Yuan waved his hand, "By the way, the necessary security procedures must still be followed. Don't worry about us, just make any requests directly."
"And the situation over there seems to be a bit complicated. In order to avoid strategic misjudgment, our spacecraft will be docked at a relatively far place... Don't worry!"
