He Yuhan didn't worry about Zhao Huaiming and them looking for bad guys, she just cared about how to fix the machine.

During this period, she read and studied a lot of information found by Du Zhuoyuan, and almost thoroughly understood the structure and principle of the machines in front of her, and her technical level improved a lot. It was also this maintenance that urged her to learn. It's really stressful and motivating!

Fortunately, the destruction of several machines is not the main components, just relatively ordinary parts, He Yuhan looked at it, if there is a design drawing, it should be able to be made in China.

He Yuhan drew the drawings of the damaged parts of the first two machines and handed them to Zhao Huaiming.

Zhao Huaiming saw that Comrade He Yuhan had drawn all the parts drawings, and he could produce them himself in China, and he admired it in his heart.

So many experts and technicians can't help it, and He Yuhan found the fault in such a short time, not to mention, even the parts drawings have been drawn.

As long as the qualified parts are produced and replaced with the machine, they can be repaired, which is not admirable.

He Yuhan and Han Yi buried themselves in the room to repair the machine first, and they didn't have to worry about how to investigate outside.

Zhao Huaiming is looking for the best manufacturer specializing in processing precision parts, and he is looking for the best technician in the factory to process the parts drawn by He Yuhan.

When Zhao Huaiming handed over a few processed parts to He Yuhan, he was also very excited, and at the same time he was also very nervous, wondering if He Yuhan could really repair the first two machines.

Zhao Huaiming did not leave the research institute, and waited for the results at the research institute.

He Yuhan is still very confident in herself, she assembled the machine little by little according to the drawings, and replaced it with newly processed parts.

She doesn't know if the accuracy of this part can be achieved, but the technology of some domestic masters is still very powerful, no worse than that of CNC machine tools.

Fortunately, the damaged parts this time are not particularly high-tech parts, otherwise she can't help it, and she can't produce it in China and can only find the original manufacturer of the machine, which is even more difficult.

The machine organization is installed, the power is turned on, and after it is turned on, it runs completely normally after a series of tests.

Han Yixian happily stretched out his thumb to his daughter-in-law, "Yuhan, amazing." ”

He Yuhan smiled: "General, average." ”

The couple looked at each other and laughed. This repaired the first machine, and there was hope for the rest.

Han Yixian was also worried that if his daughter-in-law couldn't fix the machine, she would be listed as the object of suspicion, but now it's okay, and if the machine is repaired, it will automatically be excluded from suspicion.

When Zhao Huaiming saw the machine that was already running normally, he laughed happily, stretched out his thumb at He Yuhan and said: "Comrade He Yuhan, amazing, worthy of being a mechanical expert." ”

He Yuhan shook his head and smiled: "Experts can't talk about it, they just have some experience in this area." ”

Zhao Huaiming looked around the normal machine, as if he was looking at a baby, and said with a smile: "This first machine has been repaired, and the second one should be fine." There is hope for the others. Comrade He Yuhan, everything is entrusted to you. If you have any request, just say it, and I will do my best to meet it. ”

He Yuhan said: "Minister Zhao, don't worry, I will definitely do my best." ”

The parts of the second machine were also processed and sent together this time, and after the parts were replaced, there was no accident, and the machine was also repaired, which made Zhao Huaiming even more confident. Ask people to bring over the other damaged machines.

As soon as He Yuhan saw that these damaged machines had to be repaired by her, he knew that the couple would not be able to return to Beili Village in a short time, so he asked Zhao Huaiming to bring news to the family, so as not to worry the family.

Of course, Zhao Huaiming would meet such a simple request, so he sent someone to bring news to the Han family to reassure the Han family.

The meals that Han Yixian and He Yuhan ate were all made by themselves in the space, and the meals sent to them would generally be divided separately and fed to a chicken, and if the chickens were fine, they would all be fed to the chickens.

On this day, a chicken in the space died not long after eating the meal that Han Yi fed first. He Yuhan was startled when he found out that the hen was dead, they were careful and it was right, someone must have done something to this meal.

Han Yi first put the food that had only moved a little bit away, and then asked Zhao Huaiming to be informed.

Zhao Huaiming came soon. He asked fearfully, "You didn't eat these poisonous meals, did you?"

Han Yixian said: "You also know what I did before, so I'm used to it. Besides, this time the machine was damaged and man-made, so we had to test the poison every time we ate, for fear that someone would do something to it, and this time we really found that the food was poisoned.

The food hasn't been touched yet, so go find someone to test it and see what the poison is. I guess it's probably arsenic or something. ”

Zhao Huaiming was afraid and angry in his heart, this enemy's hand was so long that he could even poison He Yuhan's food.

Zhao Huaiming said: "Comrade Yuhan, Comrade Yixian, don't worry, we will definitely find out about this matter." ”

Han Yixian didn't ask how the previous investigation was, it wasn't something he should care about. He didn't want to cause any trouble. Now he just wants his daughter-in-law to fix the machines as soon as possible so that they can go back to Beili Village.

Zhao Huaiming also strengthened the security around He Yuhan and Han Yixian.

The family in Beili Village is also worried about Han Yixian and his wife. It has been almost a month since Han Yixian and his wife went to Kyoto in a blink of an eye, and there is no sign of returning. Fortunately, someone sent a letter back before, otherwise they would have been worried about death.

During the meal, Wen Jinyu said worriedly: "This Yixian and Yuhan don't know when they will be able to come back? ”

Han Xiao comforted: "Didn't they ask them to bring back the news that they would stay in Kyoto for a long time, and they would naturally come back when the matter was done." ”

He Chenglin said: "It seems that this time the matter is not small, otherwise I would not have found Yuhan here." Yuhan and they have been gone for so long, things should be tricky. ”

Han Xiao said: "Yuhan is an expert in machinery, and Zhao Huaiming personally invited Yuhan to definitely do something mechanical." With Yuhan's ability, it should be fine. Let's wait at home. If I don't come back after a while, I'll find someone to inquire. ”

He Chenglin nodded and said, "That's the only way, I hope they go well." ”

Gu Qishen said: "Yuhan is a person with real skills, and it is estimated that he is also famous above, otherwise people would not have traveled thousands of miles from Kyoto to invite people in person." Since it was someone who asked Yuhan to go over to solve the problem, there shouldn't be anything. ”

Gu Qishen was not worried about Han Yixian and He Yuhan going to Kyoto, these two people were invincible together, and Han Yixian's fox would definitely not suffer. Anyway, others don't want to calculate the two of them.
