"Yang Gan, you were reading official documents while eating today and didn't pay attention."

"Yes, today Xiaoniang Zhang asked Mr. Cao to drink in a low voice. She is probably drunk."

Yang Gan's head instantly popped up with several big question marks, and he thought to himself.

"It's impossible. Only ordinary people would think this is the case. Anyone who is born with supernatural powers, even if they are not good at drinking, can drink a whole table by themselves without any problem."

Suddenly, the corners of Yang Gan's mouth twitched fiercely, Nima, you can't be just pretending, this, this is a bit exciting.

Zhang Yumeng was still causing trouble for Cao Wushuang, and Krisna was assisting him.

Suddenly, without any warning, Cao Wushuang turned against the guest and directly pinned Krisna and Zhang Yumeng under him.

After a while, a strange voice sounded.

Zhao Wenmo said with a smile, "Tsk, tsk, tsk, I have to change the sheets again tomorrow."

Mu Qing listened to Yang Qian's strong but slow heartbeat and said, "It's tomorrow. I have to change the sheets later. How can I sleep if they are so wet?"

An hour later, the three girls were lying on the bed like dead fish, and Yang Gan carried them to their side one by one.

The little girl had to wait for the maid to have a chance to change the bed. You must know that this bed is very huge, and the job of changing the sheets is not something that can be done by one person.

The next day.

After Yang Gan exercised and ate the morning meal, he was caught by Zhang Yumeng and ran towards the foundry.

Came to the office of the foundry and cleared out everyone except Li Wang and Ou Yexia.

Zhang Yumeng took out all the dozens of drawings and explained the principles in detail to the two of them.

Speak neither too fast nor too slowly, and try to be understood by both people. If you cannot understand, ask directly.

Surprisingly, during the explanation process, Ou Yexia asked the best questions, and he always asked at key positions.

For example, a steel rolling mill is not formed in one go. All parts need to be taken out and then assembled together.

At this step, Ou Yexia proposed that where accuracy is required, the lost wax method can be used, and accuracy can be guaranteed.

For external components that are not that important, you can directly use the beating method, so that the time will not overlap.

However, the first thing to be built was not the rolling mill, but the motor. This thing requires very strong power, and there is no trick.

For large motors, Zhang Yumeng was helpless without enough information, and could only produce 160KW motors at most.

However, she is confident that as long as this thing is built, the large motor behind it can be deduced.

With the support of Yuntong County's entire system, the molds were obtained immediately.

Zhang Yumeng frowned as he watched a cast iron motor casing being finished.

I can make do with it now, but things in the future will become more and more accurate.

Yang Qian also put forward his own suggestion to directly build a machine tool.

There is actually not much of a problem with the outside of the motor, but the inside requires slightly higher precision.

To be honest, if a stamping machine can be built, it will be really easy to produce motors in the future.

Because the casing of the motor is easier to get, but the inside is composed of layers of thin stator and rotor plates.

It is really difficult to do it purely by hand. Fortunately, there is a hydraulic hammer, otherwise it will take forever. The next step is to cast aluminum rotors.

The most uncomfortable thing now is that pure aluminum is difficult to produce and the cost is not small. Zhang Yumeng spent a lot of money to extract some aluminum of average purity.

The cast aluminum of the rotor is actually a squirrel cage, which is the coil of the rotor.

Since it is a coil and the wire resistance needs to be reduced, it needs to be made of copper or aluminum.

Since the cost of copper is greater than aluminum, aluminum is used for casting.

Zhang Yumeng also knew that if it were made of copper, Yang Qian would have high blood pressure.

Then there is the casting of the intermediate shaft, which requires using a mold made of meteorite iron, placing steel on it, and beating it hard.

Because meteorite iron is indestructible, the surface will be very smooth when taken out. However, in Zhang Yumeng's opinion, it is far worse than the one produced by machine tools, so it can only be used as it is.

Anyway, so far, I have not produced many motors, but they have never been broken.

The next step is to insert insulating paper into the grooves of the stator and rotor pieces. Zhang Yumeng personally went to the paper factory to find it. He just experimented with several types of paper and found it.

Although it is not a special insulating paper, it is better than nothing.

Yang Qian worked as a handyman. When Zhang Yumeng sweated, he would wipe it away. When Zhang Yumeng was thirsty, he would bring tea and water.

This attitude was very useful to Zhang Yumeng.

The last thing is the most troublesome. You need to pull the copper wire into a wire, and then pull it back and forth in a steel plate full of holes.

Every time it passes through a hole, the copper wire becomes thinner. After passing through more than a dozen holes, it reaches the specifications Zhang Yumeng needs.

The last step is to install a bundle of copper wires into the motor according to a specific technique.

Put the mesh lid on and you're done.

Unfortunately, it was the first time to build such a high-power motor, and it immediately failed after being powered on. After Zhang Yumeng opened it, he debugged it more than a dozen times and finally found the reason.

The 160KW motor was finally successfully developed. No, it shouldn’t be said to be developed, but copied.

With this set of procedures, a week passed.

Yang Qianze persisted for three days and then fled back to his mansion.

Just kidding, Zhang Yumeng is really amazing. Once she devotes herself to it, she won't think about anything else.

There were even several days where I boiled oil and lit lamps.

After a week of self-cultivation, the damaged parts of Yang Qian's body gradually recovered.

"When will Zhang Yumeng come back?"

In Yang Qian's study, Cao Wushuang just said something to his head when they met.

Yang Gan held the official document with a gossipy expression on his face.

"Hey, master, you have to exercise restraint on this kind of thing, it's harmful to your health."

Unexpectedly, Cao Wushuang didn't care at all and raised his eyebrows.

"I have no intention of getting married in this life, and no one is my rival, but Zhang Xiaoniang's skills are indeed good. You won't be reluctant to let her be happy with me, right?"

"No, no, just use it and don't kill it."

Cao Wushuang rarely asked Yang Qian for help, and when he did, Yang Qian backhandedly sold Zhang Yumeng, who was working hard in the factory.

"It's actually simple. I have a lot of things to do, and many of them are inseparable from Zhang Yumeng. Why don't you go to Krisna when you want to play at night? She's very interested, but you haven't paid much attention to her."

"Christina?"

Cao Wushuang pursed his lips, with a tangled expression on his face.

"Her hands are too big and not gentle enough. Forget it, I'll find a way myself. By the way, you've started to get worse recently. You'd better listen to Dr. Ge, otherwise I'm afraid it will damage your foundation."

Before Cao Wushuang could finish speaking, Lao Chen hurriedly ran in. When he saw someone there, he suddenly became silent.

Yang Gan smiled and said, "Okay, master, you go and do your work first, I have something else to do."

"Hmph~!"

Cao Wushuang walked outside with cat steps. She didn't know if the food was very good. When she walked, her water snake waist seemed to be breathing, which was really fascinating.

After Cao Wushuang left, Lao Chen immediately reported the news.

"Sir, there is something that I almost forgot. It was only after someone reminded me that I remembered it."

"Oh? It's a very important thing?"

Yang Gan's face was full of confusion. He didn't remember that he had told Lao Chen something very important.

For now, Lao Chen only needs to manage Zhuangzi well.

Zhuangzi is no longer what it used to be. It used to be just a manor, but now it has hundreds of thousands of people and countless fertile fields.

Lao Chen only needs to manage a dozen leaders, and it's no big deal.

The biggest things are nothing more than clearing wasteland, fertilizing the land, and asking for instructions for annual planting and crop rotation.

"Sir, the time has come for the prisoners of Liao and Shang to be released."

Yang Qian was stunned. Time passed so quickly. A year had passed, as if a lifetime had passed.

At that time, I just said it casually, thinking that in a year's time, there would be chaos in the Central Plains, and people would be detained for any reason.

Unexpectedly, the water in the Central Plains is deeper than imagined, which is troublesome.

"How have you treated them over the past year?"

Old Chen said honestly, "It's not bad. After all, the young master said he wanted preferential treatment, and they work very hard."

"There are even people from Liao who have accumulated more than ten shi of food and are preparing to take it back home."

Yang Gan put his mind to it and deceived his opponents, but it was nothing. These were just prisoners of war, so deceiving them seemed very clumsy.

The main reason is that the benefits of lying to them are not enough. Yuntong County is currently short of people, but the shortage is not as serious.
