Bai Chengcheng likes mechas, so he naturally likes to browse related websites. Therefore, he is still relatively familiar with the appearance and parameters of various mechas. Tuotian's fame, in addition to the fact that it is an antique that has been completely preserved for 2,000 years and can still be used normally, but also because it is the work of Lu Changgeng, a god-level mecha handmade master in history. At the auction the year before last, it was sold at a terrifying high price of 38 billion star dollars.

Out of admiration for the god-level antique mecha, Bai Chengcheng walked into the door. Don't dare to walk over in a grand manner, slowly move against the wall, quietly walk to the back of the flowing wind, and then slowly move forward to see Tuotian up close.

The mecha didn't start, and Bai Chengcheng naturally didn't know what was wrong with it. I suddenly remembered that my robot could detect the inside of objects, and I wondered if it could be used here. Quietly activate the Priya system with your mind.

What excites Bai Chengcheng is that the system can also be activated in the second world. That's for sure, the second world is the projection of consciousness, and Bai Chengcheng's ontology and its Priya are both in the link cabin at home. Bai Chengcheng's consciousness is there, and Roseya, which is linked to his consciousness, can naturally play a role.

Bai Chengcheng asked Priya, "Priya, can the Mimi robot be used here?" ”

Roseia displays through the panel: [Yes.] 】

Rosea is in a state of horror as she discovers that the systems of the Second World are much more advanced than hers. And extremely confused, since the world has such advanced information technology, why is the technology of the outside world so backward, and there is not even a machine life?

"Great." Bai Chengcheng controlled the Mimi robot to fly out of the body and burrow into the ancient mecha. No one notices this process, because the robot is similar to dark matter, countless times smaller than air molecules, not to mention invisible to the naked eye or electron microscope.

Bai Chengcheng and the Mimi robot are controlled and communicated through thought waves, so the electronic instruments on the scene did not respond at all. Only the middle-aged man who was sitting upright safely glanced at Liufeng suspiciously, and didn't see anything abnormal, so he didn't pay attention anymore.

40 billion meters of robots drilled into the Tuotian body. After a while, Bai Chengcheng got the complete structural drawings and material composition of Tuotian.

Like the old man who circled around Tuotian, Bai 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, and the lubrication was also evenly placed, and there were no slight cracks. The assembly is also absolutely in place, although the stress of the corresponding screw is not said to be absolutely the same, but its error is extremely small, and it should be assembled by a master. In other words, there is no problem with this mecha in terms of mechanics.

Is the problem in the control system? In terms of software, the level of software 2,000 years ago is naturally incomparable with today. So the problem can't be with the software. Not to mention the central controller of the Liufeng store, it is estimated that an ordinary college student, or even a middle school student, can easily handle the software of 2,000 years ago.

It's not a mechanical problem, it's not a software problem, it's just a wiring problem. Bai Chengcheng asked the Mimi robot to carefully inspect Tuotian's electronic circuits, even the inside of the integrated block. He has no way of knowing the function of each manifold, but he can observe whether there are any burned-out areas inside the manifold.

Bizarrely, I still didn't find any problems, and I didn't find a single virtual solder joint. Come to think of it, if there were these problems, it would be impossible for the frowning master not to find out.

Hell with that. Everything is fine with this mech, except for a tibia in the left leg that has been replaced, there are no other problems. Is the problem in this tibia? No, the material is more advanced than the original material.

Tuotian is made of all-titanium aluminum alloy. That tibia is a beryllium vanadium alloy. Regardless of strength or toughness, beryllium vanadium alloy is obviously superior to titanium-aluminum alloy, and it is absolutely possible to replace titanium alloy tibia.

Bai Chengcheng used the Mimi robot for the first time, and he had the urge to not give up until he found the problem. Such an artifact that can deeply observe the molecular structure can't find a problem, isn't it too scumbag?

Time passed in suffocation, and after observing for more than an hour, except for the tibia, Bai Chengcheng was stunned and did not find any fault point.

In this case, the problem must lie with the tibia of the left leg. All the robots are concentrated on the left leg and the measurements are carefully observed. In addition to the fact that the beryllium vanadium alloy tibia is proportionally longer by two nanometers because of the fineness of the processing, no problems have been found. Two nanometers, for this kind of antique mecha, is definitely within the margin of error, and the accuracy of the central control system at that time is definitely not so high, unless the system of this mecha is upgraded.

Well? It's really possible. I don't know if the original owner has upgraded the system, at least when the wind shop repairs, if the problem can't be found, most of the system will be reset. In the unlikely event that this tibia develops thermal creep and elongates a little more during movement, the system will definitely determine that it is faulty.

Thanks to Roseya's desperate indoctrination, Bai Chengcheng's knowledge of materials science has been comparable to that of college students.

Thinking of this, Bai Chengcheng finally knew the existence of the problem, that is, the person who processed the tibia ignored the phase of the beryllium vanadium alloy. It stands to reason that the cross-section of the tibia should be parallel to the molecular torus, but now it is perpendicular.

The molecular composition of beryllium vanadium alloy is like a ring like graphite. During thermal expansion and contraction, the molecular rings expand or contract, and there is almost no thermal creep in the direction of the perpendicular annular plane.

That is to say, once heated in motion, the beryllium vanadium alloy will elongate rather than thicken. The fibula is made of α titanium aluminum alloy, which has excellent thermal stability. As a result, if the mech is vigorously active for a period of time, the length of the tibia will be deformed more than that of the fibula. It already grows two nanometers, and when it is heated, it grows even more. If the accuracy of the system is too high, it will determine that the left calf has a problem similar to bone hyperplasia.

Thinking of this, Bai Chengcheng subconsciously spoke, "I know." ”

The sound was not loud, but in the silent environment, in the suffocating atmosphere, it was like thunder. All eyes were on him.

Everyone stared at it, it was a hairy boy. After being surprised, his expression was different.

The middle-aged man smiled teasingly and didn't say anything. The meaning is obvious, the dignified Master Qin can't find a problem, you a little guy who popped up out of nowhere actually said 'I know' unashamedly, isn't it grandstanding? It seems that this repair shop is a virtue from top to bottom, full of horses.

Liufeng and the others originally had a feeling of joy descending from the sky, but when they found out that it was the young uncle, they were so angry that they couldn't slap him out of the door. It's annoying enough, you handyman suddenly jumped out and babbled nonsense, because you think the face of the store is too embarrassing to get home, right?

"Shut up! Get out! The wind scolded sharply.

No one took Bai Chengcheng's words seriously, but the old man made an exception, "Slow." Little brother, tell me about it. He doesn't think Bai Chengcheng can find the fault, but when the authorities are confused and fall into a dead end, the layman's point of view may be able to wake up a line of thought.

Liufeng rushed to say angrily: "Grandpa Qin, don't listen to this kid's nonsense. He had just arrived, and he didn't even know about the malfunction of this mech. ”

Boss Qin was disappointed.

The group of bodyguards on the other side laughed.

Liufeng and the employees behind him couldn't wait to tear Bai Chengcheng.

The young man's temperament, Bai Chengcheng was not convinced, "Is this mecha lame after a period of intense activity?" ”

"Huh?" Everyone's eyes converged on Bai Chengcheng again. Apparently he was right.

Flowing Wind, "Who told you that?" ”

Bai Chengcheng raised his head arrogantly, "No one told me, Uncle Liufeng, didn't you say it?" ”

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

"The control system of this mech should not be the original. If it was its original control system, the failure would not have existed. It is precisely because of the upgrade that the accuracy of the system is too high, which leads to lame failures after the mecha has been running for a while. High precision but failure, seemingly contradictory, is not. It's because of ······. Bai Chengcheng elaborated on his judgment, and everyone was shocked.

Because of the previous discordant atmosphere, and everyone was thinking about whether Bai Chengcheng's analysis was reasonable, no one had discovered Bai Chengcheng's weirdness at this time. The mecha was assembled, how did he find out that the material of the shin inside was different? Not to mention that the fibula is also known to be the phase of the α titanium alloy as well as the tibial beryllium vanadium alloy.

"Demolition." The old man said decisively.

Liufeng and the others quickly opened the maintenance operation frame and fixed the mecha. The old man picked up his tools and quickly disassembled the two legs of the mecha. He tried it because he knew that the tibia was indeed replaced by a beryllium vanadium alloy. What he needed to verify was that the tibia was really two nanometers long, and that it was not in the right phase.

Bai Chengcheng saw a light in his eyes, a master, a real master. The old man's hands flew up and down like playing a piano, with fast, efficient and precise movements, without any superfluous movements, and the dismantled parts were placed in a neat and orderly manner.

A few minutes later, the old man took the dismantled shin in his hand and looked at it carefully, glanced at Bai Chengcheng meaningfully, and said to the convection wind: "Three-dimensional measuring instrument." ”

Without moving his hands, the wrench quickly ran to the side and pushed the laser 3D measuring instrument over, and adjusted the accuracy to the nanometer level.

There is no need to measure 3D data, just the length is enough. The old man carefully put the two shin bones into the measuring instrument, closed the sealed door, and set them on the touch panel. Everyone waited intently for about ten minutes, waiting for the temperature in the measuring instrument to be constant and eliminate thermal creep. Accurate to the nanometer level, human body temperature may affect the accuracy of the data.

See that the time is about the same, turn on the laser. The display shows the data instantly, 4173286/4173284

"Wow!" "Ahh The room was full of exclamations. It's not bad, it's unbelievable, it's too godly.

After the data came out, everyone's eyes didn't look at the mecha or the measuring instrument, but they all focused on Bai Chengcheng, as if looking at the gods. All hearts are the same, so accurate, how can he judge it?

As a result, the atmosphere in the repair shop has changed dramatically, and the employees of the repair shop have become even more excited, and the previous tension has disappeared.

Bai Chengcheng's judgment is completely correct, the fault of this mecha is that after running at full power for more than an hour, the system will determine that the left calf is faulty and has a lameness.

If the fault point is found, it will not be difficult to repair. As for whether the customer set up a bureau to extort the wind repair shop, it is no longer important. When the contradiction is resolved, there will be no fuse of sabre-rattling.

There are no high-end ray detectors in the store to determine the phase of the beryllium vanadium alloy, and that doesn't matter. To repair this fault, it is not necessary to change the phase of the beryllium vanadium alloy, there are many ways.

The employees of the repair shop, including the main style of the shop, the bodyguards of the middle-aged man who is as steady as Mount Tai, and a few tourists who watch the excitement, admire Bai Chengcheng so much. Without the help of any testing instruments and tools, it is impossible to judge the fault and find the cause of the fault with the naked eye, but he just did it, and it was exactly the same, and the fantasy became a myth.

However, there are two people who don't 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.
