In Zhang Yu's private research room, several robots around him stood quietly in the corner, watching Zhang Yu bury his head in the study of machinery and equipment.

Zhang Yu had a hint of joy on his face, after the past few days of research, his machinery and equipment finally had some results.

In the past few days, R&F Group has officially embarked on the right track, and with 60% of the property rights of Zhao's Group, his R&F Group has been transformed into a R&F Group and has been able to open up its market to other cities in Eastern Province.

After Tang Lao and the others explained a few words to Zhang Yu here, they returned to their own company and began to operate, which is why the Zhao Group and the Qian family's grandsons came to make amends.

After doing all this and helping R&F Group get through the difficulties, Tang Lao and the two were waiting for Zhang Yu's news, and they also wanted to come to Zhang Yu, but after thinking about it, if Zhang Yu saw them and mistakenly thought that they were coming to see how his machinery and equipment were being studied, it would be embarrassing, so Tang Lao and the two had to resist not coming to Zhang Yu.

Zhang Yu also knows this, even if Tang Lao and they don't mind how long it takes for them to develop machinery and equipment, but if the time drags on for a long time, Zhang Yu also feels a little uncomfortable.

Therefore, these days, Zhang Yu is eager to develop this machine and equipment.

Looking at the small power motor equipment in front of him, after being turned on and powered on, it was running at a very fast speed, and the rotation was whirring.

As the number of the test instrument jumped, Zhang Yu looked forward to looking at the digital display on the test instrument, and the time passed minute by minute, and the first small test was considered successful.

"Ten, nine, eight...... Three, two, one. Zhang Yu silently counted in his heart, as the machine stopped rotating, there were results on the test instrument, and several dazzling numbers fell in Zhang Yu's eyes.

"Whew-" Zhang Yu let out a long sigh of relief.

After half a month of research, this electric energy optimization machine finally succeeded, and the things he discussed with Tang Lao and them finally came to an end.

The production of every piece of machinery and equipment has brought convenience to human beings, but behind it is a study of several years, or even decades, and some people have studied a certain industry and studied for a whole life.

What touched Zhang Yu the most was that a product, the predecessors did not succeed in research, and the descendants continued to study, and after generations of efforts, those convenient equipment that served human beings were developed.

Zhang Yu didn't have this feeling before, but since he came into contact with the machine research industry, he has this experience.

While Zhang Yu told Li Lao and them about the knowledge of machines, he also listened to a lot of the deeds of scientific researchers who silently contributed to mankind.

Their names may not be loud enough, but the machine products they developed have become a topic of conversation on the streets.

Although Zhang Yu is not a person with great feelings, he just wants to build his own business empire, but he respects those scientific researchers who make silent contributions.

Suppressing his thoughts, Zhang Yu took out the phone and called Tang Lao, wanting to invite them to come and see his power optimization machine.

"Zhang Yu Xiaoyou, hahaha, things have been going well in the company recently!" Before Zhang Yu could speak, Tang Lao's kind voice rang out.

Tang Lao casually talked about a topic and said hello to Zhang Yu.

Tang Lao said with a smile, the company's affairs, with Tang Lao's help, will naturally go smoothly. Zhang Yu held the phone and said in an extremely polite tone.

"Oh......" Tang Lao sighed softly, and for a moment, he didn't know what to say.

"Old Tang, if you have time, come to my R&F Group, the power optimization machine I showed you before has been researched. Zhang Yu went straight to the point.

"So fast, Zhang Yu Xiaoyou is really extraordinary. Tang Lao was quite surprised, judging from the last time I learned about the situation, Zhang Yu's electric energy optimization machine was just a few drawings, plus a few micro parts.

There is not even a model, how many days have passed, and in less than a week, Zhang Yu has already developed it.

There are only two explanations for this in-depth understanding of the machine, either Zhang Yu has tested many times before, accumulated a lot of experience, and knows the machine well, so it was developed in just a few days.

There is also an explanation, that is, Zhang Yu has amazing attainments in machines, for these, there is a kind of natural grasp, this kind of machine has amazing skills, it is not impossible to study a machine and equipment in just a few days.

As for these two explanations, no matter which one they are, they cannot hide Zhang Yu's amazing ability in the research of machinery and equipment.

"Old Tang, I won't talk to you more, I still have to inform Old Xiao of them. After Zhang Yu finished speaking, the expression on his face was flat, and he said to Tang Lao, ready to call Xiao Lao and them.

"Zhang Yu Xiaoyou, Old Man Xiao's side, I will inform him that we will come to R&F Group tomorrow to see the machine developed by Zhang Yu Xiaoyou. Tang Lao wrapped up the matter of informing Xiao Lao.

As for Old Man Li's side, he didn't say much. He didn't know whether Zhang Yu would notify Old Man Li or Shengping Girl, or let Zhang Yu solve these things by himself.

"Well, thank you Tang Lao, first of all. Zhang Yu thanked him very politely and hung up the phone.

After hanging up the phone, Zhang Yu was about to call Li Lao, but looking at Li Lao and Li Shengping's phone number in the address book, Zhang Yu fell into hesitation, whether to notify Li Lao or notify Li Shengping.

This question doesn't have a lot to do with it, it's just that Zhang Yu felt a little awkward for no reason, thought about it, and called out.

"Zhang Yu, you finally know to call me. The phone was connected, and Li Shengping's smart voice rang.

"Uh......" Listening to Li Shengping's words, Zhang Yu held up the phone and was stunned for a moment, and he didn't know what to say at this time.

"Zhang Yu, is it that the matter of R&F Group has not been resolved. After Li Shengping finished speaking, he regretted a little, what kind of greeting did he look like a resentful woman.

But it's all to blame grandpa, if he hadn't let him go to Zhang Yu to talk to you, she would have been jumping in Zhang Yu's office at this time.

"No, that, Shengping, it's you who help me inform Li Lao, my new machinery and equipment have been researched, when will Li Lao have time to come and take a look." Zhang Yu thought about it and said the theme.

"Okay, Grandpa and I will be right there. Li Shengping had a hint of joy on his face, and he couldn't wait to say what he thought.

"Uh! Is Elder Li very free these days?" Zhang Yu listened to Li Shengping's words, his face darkened, what do you mean to be there soon.

"Yes, yes!" Li Shengping hurriedly said twice.

"That's it, tomorrow Tang Lao and they will also come to see my new machinery and equipment, you can also come tomorrow!" Zhang Yu made a decision.

"Okay, okay!" Li Shengping said with some pity.
