In order to repair the radio telescope, Chen Feng used up six snake gall bio-batteries, but they still didn't last long.

Fortunately, he successfully assembled a voltage regulator and made a modular wide-band power supply box that can hold twenty wolf fangs at the same time.

The principle of this thing is simple, but the stability of wolf fang bio-batteries is not as good as snake gall, the voltage frequency changes very quickly, and the energy contained in each wolf fang varies from voltage to current to frequency conversion amplitude.

In order to make this wide-band voltage regulator, Chen Feng racked his brains, combined countless components, and painstakingly figured out an adaptive energy supply system. He BOOMed it seven or eight times, and constantly fine-tuned it. It took thousands of parts to complete it successfully.

This means that his total energy control has made a big step forward.

There are many wolves in the world, and when wolf fangs are used up, they can be replaced with tiger tail joints. Chen Feng used his intelligence to solve the energy supply problem.

His confidence was greatly improved.

He even felt that if he were not alone, his energy and ability would not be enough. If he were given a few years, he could even build a pure quark directional synthesis instrument, directional void manufacturing materials, and then make a quantum chip forging machine, so that he could really solve the problem of auxiliary artificial intelligence by himself.

In short, a world full of usable garbage has created the prerequisites for his personal productivity, but his personal intelligence and empirical intuitive reaction are the core driving force for the explosion of personal productivity.

After confirming that the solar dome is really gone, Chen Feng immediately came up with a new idea.

Although the difficulty is still infinite, Chen Feng has determined three major policies.

First, further build large-scale engineering machinery to improve personal productivity.

Second, he still did not give up rebuilding artificial intelligence computing power, with the ultimate goal of cultivating an existence similar to the former intelligent assistant Xiaowei. As for the level of Fanxing, he did not dare to hope for it.

Third, assembling ships at all costs, with the ultimate goal of regaining the ability to navigate in space.

He could not count on others to save him, and he had to rely on himself for everything.

There was one thing he had not considered clearly, if there was a chance, whether he should go to the colony to take a look.

There were two possibilities now.

The compound eye civilization knew that he still existed, or it didn't know.

The second possibility was more likely.

Then if he had been lurking, independent of the human colony camp, he could quietly make trouble as long as he did not collide head-on with the compound eye fleet or its detectors.

But in this case, he would not be able to participate in the war.

Chen Feng is not so arrogant as to think that he can win the battle with his own human beings, but he is used to always charging ahead, so he will inevitably feel uncomfortable if he is an outsider.

And what if the colony's fleet is powerful enough this time and can crack more mysteries of the prism, or even break the blockade of the solar dome?

If I am isolated and cannot get detailed information, wouldn't everyone's sacrifice be in vain and a timeline be wasted?

But if I act quietly and independently, can I live a few more years, visit more galaxies, and see more cosmic miracles.

Maybe I can find new inspiration or theoretical basis from cosmic miracles and trigger revolutionary technological innovations?

So, what is the best choice?

What should I do?

Chen Feng was confused again.

The more information he got, the more logical dilemmas he faced, and the more difficult decisions he had to make.

Each decision represented different possibilities, different rewards, and different potential dangers.

These logical forks led his personal and civilizational directions to one unknown result after another, and even he found it difficult to make decisions on the spot.

What was even more difficult was that he always had someone to serve as his advisor in the past, but this time there was no one, and he had to rely on himself.

If someone else lived alone like Chen Feng with endless confusion, he would probably not be able to accomplish anything, but he didn't.

Several months passed unknowingly.

In these months, he accomplished several things.

After the spring, he returned to the tea mountain and carefully picked tea from several mountains. In the end, he roasted nearly half a ton of Chen's Houkui tea, which solved the food problem.

In addition, he controlled the construction machinery to efficiently pick up garbage and successfully welded and assembled a three-axis multifunctional underground spaceship that was nearly 50 meters long and about 16 meters high.

Chen Feng embedded almost all the functions that can be realized at present into this spaceship.

Sixteen anti-gravity engines with a total load of more than one million tons, three bidirectional jet medium engines (one large and two small) with a full load thrust-to-weight ratio of 100, an enlarged version of the gravitational wave detector with a scanning area of ​​5 kilometers in radius, a raw material preparation chamber composed of sixteen medium-sized quark detectors in parallel, a high-precision analytical purification instrument, a small ultra-high temperature nuclear fusion boiler, dozens of robotic arms with super mining capabilities, three cargo compartments of different sizes with various parts stacked in different categories, and a 1nm silicon chip lithography machine and etcher.

Yes, it is the lithography machine that people in the 21st century are very familiar with.

He did it.

He never thought that in the distant 31st century, he would return to the situation of relying on single-crystal silicon chips to solve the computing power needs.

He had no choice.

The ZS bacteria were really cruel, and they didn't leave him a single quantum chip.

After thinking about it, he could only become a cheating player in the 21st century Internet jokes, and forcibly turn sand into chips from scratch.

The nuclear fusion furnace and the analytical purification instrument solved his material needs for single-crystal silicon. After taking out the first single-crystal silicon mother disk, he could use the quark instrument to synthesize it in batches.

Then he relied purely on the chip manufacturing process structure that he had memorized from the picture memory, and first directly hand-wrote out 1μm (micrometer) chips and storage particles that were also mainly composed of silicon elements.

On March 8, 3020, a particularly memorable day, Master Chen relied on his own hands to reinvent the 386 computer.

Theoretically, his hand-engraving precision can also reach the nanometer level, but this requires too much concentration, and the fatigue brought by such fine control is also strenuous. A slight mistake will destroy the entire single crystal silicon, and everything has to be done again, and there is no way to complete it in batches.

So he chose this stupid method.

After completing the 386 computer, the next thing became much simpler.

His lithography machine process can reach 1nm, and the difficulty lies in the architecture design and the automatic programming when the machine etches the chip.

Because he made the first handmade hard drive very large, with a data storage capacity of tens of G, he successfully input the 65nm process architecture containing huge information into the computer, and successfully used a chip machine with a maximum process of 1nm to easily etch a chip.

The Core series appeared, revolutionizing computers again, improving computing power and data storage capabilities.

On April 7, 3020, Chen Feng successfully manufactured a 1nm process chip with a transistor density of 980 million per square millimeter, with a tape-out success rate of 31.7%. Three days later, he built a server consisting of 7,000 chips, and also manufactured an ultra-large-capacity solid-state hard drive with an eight-layer vertical structure of particles.

He then wrote his self-domestication algorithm into the server.

Since then, the artificial intelligence computing power in his hands has returned to the level of 2020.

This is due to both his own intelligence and the residual genes of ZS bacteria.

In order to prevent electron tunneling in 1nm chips, he originally needed to develop a new type of insulating fluid.

Needless to say, the development of materials science is difficult. He originally thought that this was a slow and time-consuming process.

As a result, when he went out hunting and continuously collected genetic information from special parts of animals, he accidentally discovered that a kind of snail oil had extremely strong insulating ability.

Chen Feng tested two chips with a try-it attitude and found that this snail oil, which was as viscous as a non-Newtonian fluid, could really be used as an insulating liquid to be packaged into the chip, and it also had excellent thermal conductivity, so the problem of the heat sink was also solved.

In short, it took him a month to improve the chip process level from 1 micron to 1 nanometer, and built a multi-parallel server system, which could basically meet the computing needs of the ship in front of him.

Although the hull cover of this ship looks like a pair of patched pants, and various probes stick out like sea urchins, it looks like a cosmic beggar, but this is something he worked hard on bit by bit, so Chen Feng is very proud of it and decisively named it Morning Breeze No. 1.

Looking at Morning Breeze No. 1, Master Chen felt a sense of pride and satisfaction.

Since the main driving force of Morning Breeze No. 1 is the repaired anti-gravity engine and there is no shield, it does not have the ability to fly off-world.

But it doesn't matter, with this ship in hand, he can do more work now.

In the slightly messy command cabin, Chen Feng, holding a cup of strong tea, pressed the take-off button with a little trepidation.

With a loud rumbling sound, the ship swayed and slowly rose into the air, creaking everywhere.

After all, it was semi-manually assembled, and some parts would not fit together so perfectly when it was launched for the first time.

The sound was intimidating, but it would not fall apart.

Morning Breeze No. 1 floated in the air for three hours, and then went back and forth from Hanzhou to the Great Snow Mountain, declaring the test flight a success.

Chen Feng was highly focused throughout the whole process, and kept the data fed back on the monitoring instrument panel firmly in his mind.

After stopping, he put on a small single-person multifunctional engineer's wear equipment, jumped up and down in Starhawk No. 1, and repaired and reinforced the unstable parts detected during the test flight.

His idea of ​​building a spaceship is very similar to the style of the Soviet big brother in the past. In short, he patched up the loose parts, not seeking beauty and refinement, but only seeking to be able to move, which has a strong flavor of chaos algorithm.

It's really useful.

After he finished a round of hammering and patching up the wrong parts, the creaking sound in the spaceship was much less when it took off again, and the parts with structural stability alarms were reduced by 95.77%.

The second test flight ended smoothly, and then patched up again.

On April 10, 3020, the third test flight ended, and there was no sound at all, and the number of alarms returned to zero.

Looking at the Morning Breeze No. 1, which was filled with more patches, Technician Chen was satisfied and gave himself a thumbs up again.

It has been nearly half a year since he traveled here, and Chen Feng has been busy.

In order to celebrate the complete stability of the spaceship, he decided to take a holiday.

It was raining outside again, but he was able to comfortably set up a beach chair under the tripod of Morning Breeze 1 and set up the induction grill.

On the metal table next to him was a whole cow that had been beautifully disassembled.

He placed the two horns aside separately. These were two large bio-batteries, more useful than wolf teeth.

"Xiao Wei, make me a steak, medium rare."

Chen Feng said, waving his hands while lying on the beach chair.

Next to him was a 1.5-meter-tall tracked robot.

The two mechanical arms of the robot were different colors, one yellow and one blue.

The blue one has 360-degree shoulder and elbow rotation performance, a hydraulic lifting force of 3,200 kg, and was produced in 2315 and excavated from an underground obsolete warehouse of a factory in Hanzhou.

The yellow one is slightly longer, with a snake-neck multi-link structure, relying on organic metal extension and bending to generate power, with eight fingers, and a lifting force of only 765 kg, but it is more flexible. It was produced in 2416 and excavated from a workshop warehouse in a city on the eastern coast.

In order to make it worthy of the feminine name of Xiaowei, Chen Feng also covered the back of its head with coconut palm, which can be considered as long hair.

Xiao Wei: "Sorry, your Mandarin is not standard enough, please give the command again."

"Steak! Medium rare!"

"Okay."

After receiving the message through the voice recognition system, the robot Xiao Wei creaked and moved to the metal table, and began to fry the steak according to the preset program.

Chen Feng stood by and watched for two minutes, then opened Xiao Wei's central control box and adjusted the capacitor voltage to make Xiao Wei's force control more precise when frying steak. After another minute of observation, it was done.

He took another sip of tea and sat on the beach chair to write in his diary.

"It's the 167th day since I came here. Morning Breeze No. 1 is running well."

"Since Xiaowei was created three days ago, there is finally a 'person' who can talk. But it's still lonely."

"Because of drinking tea, the voice in my head is getting louder and louder, the information I get is getting more and more dense, and my sleep quality has declined."

"I haven't spoken for too long, and my Mandarin has deteriorated, hahahaha! How embarrassing."

"My gene awakening has increased to 42.81%, but the improvement speed has been slower and slower recently. The effect of the tea has declined, and I don't know when it will stop."

"I still haven't found the reason for the defeat."

"Still haven't obtained the aerospace capability and quantum network."

"I want to go home and talk to people, but I can't leave yet. I have a feeling that if I go back empty-handed this time, the next time I will still be waiting for the end of the world."

"I, Chen Feng, am the most tolerant and the strongest person on Earth. If I give up, then no one else can do it."

"The next goal is to use Morning Breeze No. 1 to build a spacecraft as soon as possible. Continue to expand computer performance. If it doesn't work, you can also try shieldless interstellar navigation. I can't sit and wait for death."

"No matter what choice I make, I must leave the earth."

After writing this paragraph, he drank another cup of tea, and then his head suddenly became groggy and extremely sleepy.

But at this time, Xiaowei was already walking towards him with a freshly fried steak.

There was a problem with the program settings. Xiao Wei's long yellow arms like iron clamps grabbed the scalding steak and stuffed it into his mouth. It was burned enough that his slightly drowsy head immediately regained some clarity. Chen Feng's

mouth was burning with pain. He quickly spit out the steak, broke away from Xiao Wei's claws, and hooked his hand into his mouth. There was blood on his fingers.

Technician Chen rolled his eyes and jumped back to Morning Breeze No. 1. He turned on the probe-type quark therapy device that had just been modified not long ago, and scanned his mouth first to prepare for repairs.

At this moment, a picture suddenly flashed on the LCD panel in front.

The data displayed on this LCD panel was the result of his personal genetic analysis, usually a long string of binary numbers, and he relied on his naked eyes to observe to extract information.

But this time it seemed that there were too many numbers, the font was too small, and the stacking was too dense.

Countless 0s and 1s eventually formed a photo.

Chen Feng was stunned.

He knew the person in the photo.

Sergei Bonomarenco.

The most brilliant and talented of all his younger brothers.

Chen Feng was shocked and his mind was full of questions.

What does it mean?

This information comes from my brain?

The therapeutic device scans the mouth, which is very close to the brain.

The noise in the brain just now was very loud, so loud that it exceeded a certain limit and seemed to have become a readable signal.

The signal must be part of the command given by the ZS bacteria to the animal.

But other orders are very broad hostile awareness, why is there a photo of Sergei?

Five hundred years have passed, and the ZS bacteria still remember this man's face?

What does it mean?

Is the little brother so proud?

More proud than me?

Chen Feng does not deny Sergei's talent, but compared to his own achievements, it is definitely worse.

If the compound eyes just want to pay attention to humans with higher threats, they should not attach so much importance to Sergei.

This is unreasonable!

Wait...

He suddenly realized, could it be that Sergei is still on Earth?

So he is still on the ZS bacteria's hostile wanted list, and the priority is the highest and strongest?

After this thought came up, it was out of control.

The more he thought about it, the more possible it was.
