Bo Chengcheng likes mechas and naturally likes to browse related websites. Therefore, he is relatively familiar with the appearance and parameters of various mechas. Tuotian is famous for being a two-thousand-year-old antique that has been completely preserved and can still be used normally.

In addition, it is also because it is the masterpiece of Lu Changgeng, the great mecha craftsman in history. At the auction the year before last, it sold for a terrifying high price of 38 billion star yuan.

Out of admiration for the god-level antique mecha, Bo Chengcheng walked into the door. He did not dare to walk over grandly, and moved slowly along the wall with small steps, quietly walked to the back of Liufeng's side, and then slowly moved forward.

Take a closer look at Tuotian.

The mecha didn't start, so Bo Chengcheng naturally didn't know what was wrong with it. He suddenly remembered that his Yaomi robot could detect the inside of objects, and wondered if it could be used here. He quietly used his mind to activate the Peliya system.

What excites Bo Chengcheng is that the system can also be activated in the second world. This is for sure. The second world is a projection of consciousness. Bo Chengcheng's body and Pelia are both in the link cabin at home. Bo Chengcheng

His consciousness is there, and Pelia, who is linked to his consciousness, can naturally also play a role.

Bo Chengcheng asked Poliya, "Poriya, can the Yaomi robot be used here?"

Polya displayed through the panel: [Yes.]

Pearliya was in a panic. She discovered that the system in the second world was much more advanced than hers. She was also extremely confused. Since this world has such advanced information technology, why is the technology in the outside world so backward? Even a machine

No life?

"Great." Bai Chengcheng controlled the Yaomi robot to fly out of the body and get into the ancient mecha. No one noticed this process, because the Yaomi robot is similar to dark matter and is countless times smaller than air molecules, let alone the naked eye.

Can't even be seen with an electron microscope.

Bo Chengcheng and Yaomi robot controlled and communicated through thought waves, so there was no response from the electronic instruments on site. Only the middle-aged man who was sitting peacefully glanced at Liufeng in confusion and saw nothing unusual.

, and no longer pay attention.

The 40 billion unit-meter robot drilled into Tuotian's body. After a while, Bo Chengcheng obtained the complete structural diagram and material composition of Tuotian.

Like the old man who circled Tuotian, Bo Chengcheng frowned. Although he didn't know the original structure of this mecha, all the mechanical parts of this mecha, including every bearing marble, were intact.

, the lubrication is even and in place, and there are no even tiny cracks. The assembly is absolutely in place. Although I can’t say that the stress of the corresponding screws is absolutely the same, the error is extremely small. It should be assembled by a master. In other words, mechanically

There is no problem at all with this mecha.

Could it be that the problem lies in the control system? In terms of software, the level of software two thousand years ago is naturally incomparable with today. So the problem cannot be in the software. Let alone the central controller of Liufeng Store, he is probably an ordinary college student or even a middle school student.

A top student can easily master software from two thousand years ago.

It's not a mechanical problem or a software problem, it can only be a wiring problem. Bai Chengcheng asked Yaomi Robot to carefully check Tuotian's electronic circuits, even the inside of the integrated block. He had no way of knowing the details of each integrated block.

Function, but you can observe whether there is any burnt place inside the integrated block.

The strange thing is that no problem was found, and not a single false solder joint was found. Think about it, if there are these problems, it is impossible that the frowning master can't find them.

This is crazy. Everything about this mecha is normal. Except for the replacement of a tibia on the left leg, there are no other problems. Is the problem with this tibia? No, the material is higher than the original material.

Tuotian is made of titanium-aluminum alloy. The tibia is made of beryllium-vanadium alloy. In terms of strength and toughness, beryllium-vanadium alloy is obviously better than titanium-aluminum alloy.

(This chapter is not finished, please turn the page)

It is absolutely possible to replace the titanium alloy tibia.

It was the first time Bo Chengcheng used the Yaomi robot, and he had the urge to never give up until he found a problem. Such an artifact that can deeply observe the molecular structure can't find a problem, wouldn't he be such a scumbag?

Time passed in a suffocating manner. After observing for more than an hour, Bo Chengcheng could not find any fault points except for the tibia.

In this case, the problem must lie with the left leg tibia. Concentrate all the robots on the left leg and observe and measure carefully. In addition to the precision of the processing, the beryllium vanadium alloy tibia is two nanometers longer in proportion.

, still no problem was found. Two nanometers, for this kind of antique mecha, is definitely within the error range. The accuracy of the central control system at that time was definitely not so high, unless the system of this mecha was upgraded.

Hmm? It's really possible. I don't know if the original owner has upgraded the system. At least when the Liufeng shop repairs it, if the problem cannot be found, it will probably reset the system. If the tibia develops thermal creep, it will be stretched again during exercise.

If it takes longer, the system will definitely determine that it is faulty.

Thanks to Polya's hard work, Bo Chengcheng's knowledge of materials science is comparable to that of a college student.

Thinking of this, Bo Chengcheng finally knew the problem, that is, the person who processed the tibia ignored the phase of the beryllium vanadium alloy. Logically speaking, the cross section of the tibia should be parallel to the molecular torus, but now it is vertical

.

The molecular structure of beryllium vanadium alloy is ring-shaped like graphite. During thermal expansion and cold contraction, the molecular ring expands or contracts, and there is almost no thermal creep in the direction perpendicular to the ring surface.

That is to say, once it is heated during exercise, the beryllium vanadium alloy will elongate rather than become thicker. However, the fibula is made of α-titanium aluminum alloy, which has excellent thermal stability. This makes this mecha if it has been active for a period of time.

, the length deformation of the tibia will be greater than that of the fibula. It already grows two nanometers, and will grow even more after being heated. If the system's accuracy requirements are too high, it will determine that there is a problem similar to bone hyperplasia in the left calf.

Thinking of this, Bo Chengcheng subconsciously said, "I understand."

The sound was not loud, but in the silent environment and the suffocating atmosphere, it was like thunder. Everyone's eyes invariably focused on him.

Everyone took a closer look and saw that it was a young boy. They were surprised and had different expressions.

The middle-aged man smiled teasingly and didn't say anything. The meaning was very obvious. Master Qin couldn't find the problem. You, a little guy who just jumped out of nowhere, said "I got it" so brazenly. What else is it if it's not grandstanding?

It seems that this repair shop is a virtuous business from top to bottom and is full of horse racing.

Liu Feng and others had a feeling of joy falling from heaven, but when they found out it was the young uncle, they were so angry that they wanted to slap him out. It was already annoying enough. You, a handyman, suddenly jumped out and talked nonsense. You are dissatisfied with the face of our store.

You can’t even get home if you throw it away, right?

"Shut up! Get out!" Liu Feng yelled.

No one took Bo Chengcheng's words seriously, but the old man was an exception, "Hold on, little brother, tell me." He didn't think Bo Chengcheng could find the fault, but the authorities were confused and fell into a dead end.

A layman's perspective may spark an idea.

Liufeng said angrily: "Grandpa Qin, don't listen to this kid's nonsense. He just came here and he doesn't even know the malfunction of this mecha."

Boss Qin was disappointed.

The group of bodyguards opposite burst into laughter.

Liu Feng and the employees behind him wanted to tear Bo Chengcheng apart.

Bo Chengcheng was unconvinced by his youthful nature, "Will this mecha become lame after vigorous activity for a period of time?"

"Huh?" Everyone's eyes focused on Bo Chengcheng again. Obviously he was right.

Liufeng, "Who told you

(This chapter is not finished, please turn the page)

of?"

Bo Chengcheng raised his head arrogantly, "No one told me, Uncle Liufeng, just say it, right?"

This time it was the old man who rushed to speak, "That's right. Then tell me, what is the cause of this malfunction?"

"The control system of this mecha should not be the original one. If it were its original control system, the fault would not actually exist. It is precisely because it has been upgraded that the accuracy of the system is too high, which causes the mecha to become lame after running for a period of time.

Fault. High precision but failure occurs. It seems contradictory, but it is not. This is because..." Bo Chengcheng explained his judgment in detail, and everyone was surprised and confused.

Because of the previously disharmonious atmosphere and the fact that everyone was thinking about whether Bo Chengcheng's analysis was reasonable, no one had discovered Bo Chengcheng's weirdness at this time. The mecha was assembled, so how did he find the material of the tibia inside?

Different? Not to mention knowing that the fibula is made of alpha titanium alloy and the tibia is a beryllium vanadium alloy.

"Tear it down," the old man said decisively.

Liufeng and others quickly moved the maintenance rack over and fixed the mecha. The old man picked up the tools and quickly disassembled the two legs of the mecha. The reason why he tried it was because he knew that the tibia was indeed replaced by beryllium vanadium alloy.

.What he needs to verify is whether the tibia is really two nanometers long and out of phase.

Bo Chengcheng's eyes dazzled when he saw it, a master, a real master. The old man's hands were flying up and down like playing a piano, his movements were fast, efficient and precise, without any unnecessary movements, and he placed the disassembled parts in an orderly manner.

Neat and orderly.

A few minutes later, the old man took the removed tibia and inspected it carefully. He gave Bo Chengcheng a meaningful look and said, "Three-dimensional measuring instrument."

Without Liu Feng using his hands, Wrench quickly ran to the side, pushed the laser three-dimensional measuring instrument over, and adjusted the accuracy to the nanometer level.

There is no need to measure three-dimensional data, just measuring the length is enough. The old man carefully put the two tibias into the measuring instrument, closed the sealed door, and set it on the touch panel. Everyone waited attentively for about ten minutes, waiting for the measuring instrument.

The internal temperature is constant, eliminating thermal creep. Accurate to the nanometer level, human body temperature may affect data accuracy.

See if the time is about the same, turn on the laser. The display will show the data immediately, 4173286/4173284

"Wow!" "Ah!" The whole room exclaimed. It was so accurate that it was unbelievable. This must be amazing.

After the data came out, everyone's eyes did not look at the mecha or the measuring instrument. They all focused on Bai Chengcheng, as if they were looking up to a god. Everyone was unanimous and it was so accurate. How could he make the judgment?

The atmosphere in the repair shop has changed drastically, and the employees in the repair shop are even more excited, and the previous tense situation has disappeared.

Bai Chengcheng's judgment was absolutely correct. The problem with this mecha was that after running at full power for more than an hour, the system would determine that the left calf was malfunctioning, resulting in lameness.

Once the fault point is found, the repair will not be difficult. It doesn't matter whether the customer set up a trap to blackmail the Liufeng repair shop. When the conflict is resolved, there will be no trigger for tension.

The store does not have a high-end radiation detector and cannot determine the phase of the beryllium-vanadium alloy, which is not important. To repair this fault, it is not necessary to change the phase of the beryllium-vanadium alloy. There are many methods.

The employees of the repair shop, including the shop owner Feng Feng, the bodyguards of the stable middle-aged man, as well as a few tourist-like idlers watching the excitement, admired Bai Chengcheng very much. Without the help of any testing instruments and tools, he could

It is impossible to judge the fault and find the cause of the fault with the naked eye, but he did it exactly, and the fantasy became a myth.

However, there are two people who do not believe in God, one is Master Qin, and the other is the middle-aged man with his own aura. They feel that there is probably a ghost behind the incident.
