He Yuhan didn't care about Zhao Huaiming and his team finding the bad guys; she was only concerned with fixing the machine.
During this time, she read and studied a large amount of material that Du Zhuoyuan had found for her, thoroughly understanding the structure and principles of the machines in front of her, and her technical skills improved significantly. This repair work also forced her to continue learning. Pressure truly is a powerful motivator!
Fortunately, the damaged parts of the machines were not the main components, but rather ordinary parts. He Yuhan thought that if there were design drawings, they should be able to be made domestically.
He Yuhan drew up the blueprints for the damaged parts of the first two machines and handed them to Zhao Huaiming.
When Zhao Huaiming saw that Comrade He Yuhan had drawn up the parts drawings, he was filled with admiration, knowing that they could be produced domestically.
So many experts and technicians couldn't figure it out, but He Yuhan not only found the fault in such a short time, but also drew the parts diagram.
As long as qualified parts are produced and replaced with machine parts, the problem can be fixed. You have to admire them.
He Yuhan and Han Yixian were engrossed in repairing the machine in their room; they didn't need to worry about the investigation outside.
Zhao Huaiming found the best manufacturer specializing in precision parts, and also found the best technicians in the factory to process the parts that He Yuhan had drawn up.
When Zhao Huaiming handed over the processed parts to He Yuhan, he was both excited and apprehensive, wondering if He Yuhan could really fix the first two machines.
Zhao Huaiming did not leave the research institute; he stayed there to wait for the results.
He Yuhan was still very confident in herself. She assembled the machine piece by piece according to the blueprints and replaced the parts with newly processed ones.
She didn't know if the precision of the part could be achieved, but some craftsmen in China were very skilled, no worse than those produced by CNC machine tools.
Fortunately, the damaged part wasn't a particularly high-tech component; otherwise, she wouldn't have been able to do anything. Since it can't be produced domestically, she would have had to contact the original manufacturer of the machine, which would have made things even more difficult.
After the machine was assembled, powered on, and turned on, it ran perfectly normally after a series of tests.
Han Yixian happily gave his wife a thumbs up, "Yuhan, you're amazing."
He Yuhan smiled and said, "It's so-so."
The couple looked at each other and laughed. With the first machine fixed, there was hope for the others.
Han Yixian was worried that if his wife couldn't fix the machine, she might be suspected. Now that the machine is fixed, she's automatically out of the running.
When Zhao Huaiming saw the machine running normally, he laughed heartily and gave He Yuhan a thumbs up, saying, "Comrade He Yuhan, amazing! You truly deserve to be called a mechanical expert."
He Yuhan shook her head and smiled, "I wouldn't call myself an expert, I just have some experience in this area."
Zhao Huaiming looked at the working machine again and again, as if it were a treasure, and said with a smile, "The first machine is fixed, the second one should be fine too. There's hope for the others as well. Comrade He Yuhan, I'm entrusting everything to you. Just tell me what you need, and I will do my best to meet it."
He Yuhan said, "Minister Zhao, please rest assured, I will do my best."
The parts for the second machine were also pre-processed and delivered this time. After the parts were replaced, the machine was repaired as expected, which greatly boosted Zhao Huaiming's confidence. He then had the other damaged machines moved over as well.
When He Yuhan saw that all the damaged machines needed her to repair, she knew that she and her husband would not be able to return to Beili Village for a while, so she asked Zhao Huaiming to send a message home to avoid worrying her family.
Zhao Huaiming would naturally grant such a simple request, so he sent someone to deliver a message to the Han family to put their minds at ease.
Han Yixian and He Yuhan cooked all their meals themselves in the space. The food delivered to them would usually be set aside and fed to a chicken. Only after the chicken was alright would the rest of the food be fed to it.
One day, a chicken in the space died shortly after eating the food Han Yixian fed it. He Yuhan was shocked to find the hen dead; their caution was indeed correct—someone had definitely tampered with the food.
Han Yi first put the food, which had only been slightly touched, back in its original state, and then had someone notify Zhao Huaiming.
Zhao Huaiming arrived quickly. He asked, still shaken, "You didn't eat any of that poisoned food, did you?"
Han Yixian said, "You know what I used to do, so I'm used to being careful. Besides, this machine malfunction was caused by someone, so we always test the food for poison before eating, just in case someone tampers with it. This time, we actually found that the food was poisoned."
The food hasn't been touched yet. You should have it tested to see what kind of poison it is. I suspect it might be arsenic or something similar.
Zhao Huaiming felt both fear and anger. The enemy's reach was truly extensive; they even managed to poison He Yuhan and the others' food.
Zhao Huaiming said, "Comrade Yuhan, Comrade Yixian, rest assured, we will definitely investigate this matter thoroughly."
Han Yixian didn't ask how the investigation into the previous matter was going; that wasn't his concern. He didn't want to get involved in any trouble. All he wanted now was for his wife to fix the machines as soon as possible so they could return to Beili Village.
Zhao Huaiming also strengthened the security around He Yuhan and Han Yixian.
The family in Beili Village was also worried about Han Yixian and his wife. Almost a month had passed since they went to Kyoto, and there was still no sign of them returning. Fortunately, someone had sent a letter back earlier; otherwise, they would have been terribly worried.
During the meal, Wen Jinyu said worriedly, "I wonder when Yixian and Yuhan will be back? They've been gone for almost a month."
Han Xiao comforted him, "Didn't Yi Xian and the others send word back that they would be staying in the capital for a long time? They'll come back naturally once they've finished their business."
He Chenglin said, "It seems this matter is quite serious, otherwise they wouldn't have come to Yuhan's place. Yuhan and the others have been gone for so long, the matter must be rather complicated."
Han Xiao said, "Yuhan is a mechanical expert. Zhao Huaiming personally came to invite Yuhan, so it must be a mechanical matter. With Yuhan's abilities, it shouldn't be a problem. Let's just wait at home. If she doesn't come back after a while, I'll have someone inquire about it."
He Chenglin nodded and said, "That's all we can do. I hope everything goes well for them."
Gu Qishen said, "Yuhan is a truly capable person, and she probably has a reputation in higher places. Otherwise, people wouldn't have come all the way from Kyoto to invite her. Since they invited Yuhan to solve the problem, there shouldn't be any problems."
Gu Qishen wasn't worried at all about Han Yixian and He Yuhan going to Kyoto. The two of them together were invincible, and that cunning Han Yixian would definitely not suffer any losses. In any case, no one could outmaneuver them.
