Han Yixian and He Yuhan were only limited to the words related to this machine, and they would not say anything else, so as not to be heard and aroused suspicion.

Han Yixian actually had a good guess. This room was indeed monitored, and this is also for the safety of the instrument. After all, this instrument is too important and cannot be missed.

He Yuhan first started the machine to find the fault, and then recorded the abnormal parts of the machine one by one.

She was not in a hurry to dismantle the machine. She had to fully understand the structure of the machine before acting.

At noon, He Yuhan and Han Yixian locked the door of the room and went back to their resting room. A special person was there to deliver lunch to them.

The couple still didn't eat the food they sent, but they still had it in the space. Han Yixian specially circled out a few chickens in the space, and the food they sent was fed to the space.

This is also the cautious side of Han Yixian. After all, he has experienced too much and will not easily trust anyone outside.

After dinner, Han Yi locked the door and stayed in the room to watch. He Yuhan entered the space to contact Du Zhuoyuan.

The machine that He Yuhan is going to repair is almost an eradicated machine from Du Zhuoyuan. It is easy to find information about all aspects of the machine. Based on Du Zhuoyuan's connections, he quickly found the information that He Yuhan wanted.

He Yuhan laughed silently as he looked at the detailed information. There were even design drawings and other related information in this information, but it was not impossible for her to produce the same machine. It was just that there was no need now.

He Yuhan used the lunch break to read the drawings and related materials and knew it well.

In the afternoon, He Yuhan was about to dismantle the machine to check the fault points inside.

Han Yixian looked at his wife holding a bunch of drawings and asked, "Yuhan, how about it, is it okay?"

He Yuhan said: "It's almost the same. Disassemble the machine in the afternoon."

After lunch break, He Yuhan and Han Yixian returned to the room for repairing the machine and officially began to dismantle the machine.

It is much more convenient for He Yuhan to dismantle the machine with drawings. She placed the removed machine parts neatly one by one on the long table in order, and then carefully inspected each part.

Things went very smoothly, and soon He Yuhan found the reason for the machine failure. The problem was a small inconspicuous part, which was really difficult for ordinary people to find out the problem.

If the main parts are broken, it may be easy to find, and it is difficult to find such a small part.

He Yuhan also discovered a serious problem. When she checked this small part with a magnifying glass, she found that it was not natural damage, but artificial damage, which means that the machine was malfunctioning.

He Yuhan immediately wrote this discovery on paper and told Han Yixian.

Han Yixian frowned immediately when he saw what He Yuhan wrote on the paper. It seemed that the instrument was damaged by failure and there was still a big problem.

Who destroyed this machine? Are the several instruments that failed in the institute all man-made damage? Is there any conspiracy?

Han Yixian also experienced various conspiracies. He immediately thought that the things studied in this institute were all very important to the country, and some people must have deliberately sabotaged them.

Han Yixian immediately asked He Yuhan to stop. This matter was very serious and must be reported immediately.

After that, Han Yixian stopped letting his wife intervene, which was his specialty. He immediately asked someone to notify Zhao Huaiming that he still needed some special tools, otherwise the machine would not be able to be disassembled.

When Zhao Huaiming received the report, he wondered if he had prepared all the tools for He Yuhan before? Why are there still missing tools?

He did not delay nor sent anyone to ask, so he came to the institute in person.

He entered He Yuhan and his friends' room to repair the machine and saw that there were a series of parts on the long table, and the machine had been removed.

He was about to speak, Han Yixian made a gesture. Zhao Huaiming stopped talking as soon as he saw Han Yixian's gesture, and walked to Han Yixian with a serious expression.

He asked in a low voice: "Is there any problem?"

Han Yixian said: "Let's find a quieter room to talk."

Zhao Huaiming knew when he heard this that He Yuhan and Han Yixian had some major discoveries. They were afraid that the room would be unsafe.

Zhao Huaiming said, "Let's go, you guys come with me."

He Yuhan locked the door, and the couple followed Zhao Huaiming to a room on the third floor.

Zhao Huaiming asked with a serious expression: "Comrade He, Comrade Han, what is the important thing for you to come to me in such a hurry, right?"

Han Yixian said: "Minister Zhao, Yuhan inspected all parts and found that the main parts were good, but there was an inconspicuous and very difficult to damage. After Yuhan's identification, she believed that it was intentional damage by man. Although the traces were not obvious, the traces could also be seen."

Zhao Huaiming frowned when he heard this, "Are you saying that someone deliberately destroyed this instrument? Then the purpose is self-evident, just to hinder the smooth progress of the research at the institute.

It seems that this is a conspiracy. The other failures may be human-made damage.

Fortunately, you came and found such a major clue. No one had touched this machine after it malfunctioned. Comrade He Yuhan was the first to dismantle it, so the traces left by the maintenance staff were ruled out."

Han Yixian said: "I don't think this is leaked in advance. You can investigate it quietly in private."

Zhao Huaiming nodded and said, "It is true that we can't alarm the snake. We have to investigate secretly first. You should also pretend to find the fault first and make the illusion that there is no fault. I will check the suspicious person first before talking about it."

Han Yixian said: "We will work hard to cooperate with you."

After Zhao Huaiming and Han Yixian and the others talked, they sent someone to send He Yuhan a lot of tools. He Yuhan and Han Yixian also pretended to check for failures in the room every day, but found nothing.

In order to make it more certain whether there was a conspiracy, Zhao Huaiming asked someone to bring two damaged instruments to He Yuhan, and the instruments were placed in one room.

He Yuhan asked Du Zhuoyuan to continue collecting information, and she continued to be familiar with the information.

Through the inspection of the other two machines, they were all artificially damaged, which shows that there was a huge conspiracy among them. Some bad guys sneaked into the institute to carry out damage.

It is not certain whether it is someone who came in outside or someone inside the institute.

The people who both Zhao Huaiming and Han Yixian tend to do sabotage are those inside the institute. Because it is difficult for people outside such a confidential place to come and not talk about them, and they cannot access these instruments and equipment.
