After sending Li Shengping back, Zhang Yu buried his head in his private research institute, and he planned to use one night to make his own products with Zhou Long.

Tomorrow, I will show it to Mr. Li and talk to him about the follow-up development.

Regarding Li Lao's strange performance today, Li Shengping's words also made Zhang Yu think about everything.

Mr. Li brought machinery and equipment over today to talk about the development of business, not to talk about the research of machinery and equipment, because Mr. Li now desperately needs a batch of valuable commercial machinery and equipment to tide over this difficult time for the Li family.

"Zhou Long, Zhou Hu, you work hard tonight, I want to produce a batch of machine parts. Zhang Yu said slowly to the two brothers Zhou Long.

"Boss, look at what you said, what's so hard about this, it's our job to help you produce machine parts. Zhou Long replied.

Zhang Yu didn't speak, just took the drawings in his hand to Zhou Long, and then he was responsible for some difficult parts, processing some first, and then using them later.

Zhang Yu selected a few special metals, compared them, estimated them, and made the parts that were probably needed, and there was no problem.

Turned on the machine and began to get busy, the two brothers of Zhou Long on the other side glanced at each other and began to divide the labor, one was responsible for selecting materials, and the other began to process, with the sound of machinery and equipment.

Before they knew it, the moon was rising in the sky, and they were busy until late at night, looking at the parts in front of them, and there were only a few left, and they were all finished.

After Zhang Yu made a few main parts, he began to assemble them, while Zhou Long and Zhou Hu made all the parts.

Zhou Hu wiped the newly machined parts with strips of cloth.

Zhou Long stopped the machine, cleaned it up, and then wiped the processed parts with Zhou Hu and brought them to Zhang Yu.

"You two should go back and rest first!" Zhang Yu took the parts

"Boss, it's still early, if there's anything you need us to help with, just say. Zhou Long said with a smile.

"It's still early, it's already past one o'clock, okay, I'm ready to go to bed, you help me take these assembled machines and equipment to my private research room, and go back to sleep!" Zhang Yu said with a smile.

I thought in my heart that my two assistants were too real, and other assistants, when they heard the boss say that they were off work, which one of them was not as happy as the students who got out of school.

The two brothers nodded and cautiously took the machine and walked towards Zhang Yu's private research room, in their hearts, Zhang Yu's position was naturally not comparable to that of ordinary bosses.

Zhang Yu yawned, simply tried the machinery and equipment, and the assembly was almost done, as for the finished product, he could get it again tomorrow, and now that it has been made, there is no hurry.

After taking the machinery and equipment and the remaining parts to his private research room with the two brothers Zhou Long, Zhang Yu also went back to his residence in R&F Group, took a shower, and fell asleep slowly.

Tomorrow, I will talk to Mr. Li about the commercial development of the new machine, and we must maintain our spirits.

Early the next morning, Mr. Li came to pour down Zhang Yu's R&F Group and sat in Zhang Yu's office waiting for Zhang Yu.

Zhang Yu has just gotten out of bed now.

Zhou Long didn't call Zhang Yu, after all, they all slept late yesterday, he first took Li Lao and them to the office, poured a cup of tea for the two, and sat aside and waited for Zhang Yu.

Zhang Yu's last recruitment of a secretary was secretly calculated by Zhao Yitai, and later, he did not consider recruiting a secretary again.

This part of the work is handed over to Zhou Long, and the time of Zhou Long's two brothers is usually free, and Zhang Yu is not a frequent guest here.

As for the R&F Group that waited for Zhang Yu in the future, it became a foreign trade enterprise, and there were more customers to contact when talking about business, so it was not too late to consider recruiting a receptionist at that time.

"This little brother, Zhang Yu Xiaoyou, is he busy with something?" After Li Lao heard his granddaughter Li Shengping's words yesterday, he was a little excited in his heart, and rushed over early in the morning.

I didn't see Zhang Yu, so I was a little anxious for a while, so I asked.

"Our boss studied the machinery and equipment yesterday, it was too late to study, and he is still resting. Zhou Long said truthfully.

Zhou Long looked tigerish, but others were not stupid, and knew the relationship between the boss and Li Lao, so he said truthfully.

"Oh, can that little brother talk to me about your boss's deeds?" Hearing this, Li Lao was a little embarrassed, thought about it, and changed the topic.

"When it comes to my boss's deeds, it's wonderful, the first time I saw our boss, I knew that he was extraordinary, improving the machine, improving the efficiency of the machine......" Hearing Li Lao ask, Zhou Long was also completely interested, and slowly spoke, telling Zhang Yu's story briefly.

After Zhang Yu woke up, he learned that Li Lao was waiting for him in the office, so he hurried over, and before he came in, he heard Zhou Long talk about his own affairs.

"Ahem. Zhang Yu coughed dryly, and Zhou Long stopped his words and called the boss in embarrassment.

"You go get busy first!" Zhang Yu said indifferently.

Zhou Long nodded and left here, still a little scared in his heart, don't talk about these things casually in the future, although what he said is good, but don't do this kind of thing well.

"Elder Li, my assistant likes to brag a little, don't mind. Zhang Yu didn't think so much, and said with a smile.

Zhang Yu Xiaoyou laughed, I listened to the little brother's words, it didn't look like bragging. Li Lao said with a smile.

"Old Li, let's not talk about this, I'll take you to see my new machine and equipment. Zhang Yu directly pointed to the theme.

Li Lao nodded, and under the leadership of Zhang Yu, he ran towards his private research room, and Li Shengping followed the two curiously.

"Zhang Yu Xiaoyou, this is your private research room, right? With Zhang Yu Xiaoyou's understanding of machinery and equipment, your private research room is worth the old man's expectations!" Li Lao looked at the house in front of him and quipped.

Li Lao said and laughed, just some gadgets, what to expect. Zhang Yu said with a smile

As the door opens, there are seven living machines inside, which are the most conspicuous.

Li Shengping instantly became interested, and looked at it, if it weren't for the fact that her grandfather cared about Zhang Yu's new machinery and equipment, she would definitely check Zhang Yu's seven robots.

"This is the new machine and equipment product I have made, and I plan to try it out on the light rail first, and I think the current light rail speed can be improved. Zhang Yu pointed to his machinery and equipment and said slowly.

The front machine, the gears, are now mounted on a chain and are placed on the vehicle.
