For Li Shengping's special eyes, Zhang Yu naturally caught it, his eyes flickered, and he was also curious about what this girl wanted to do.

"Let's take the recent machine research knowledge, in the process of machine acceleration, there is a transformation of the force in it. Tang Lao picked up the teacup, took a sip, and asked a relatively simple question.

He still remembers a long time ago, when Li Shengping first came into contact with the machinery and equipment research industry, he asked this question, but he made this girl anxious, and he read the book for several days, and finally he didn't know the answer.

Later, Tang Lao had something to do, and this matter was over.

"Okay! Grandpa Tang actually made fun of me about this again, really, I don't know, but the one next to me, he knows. Li Shengping showed a mischievous smile, shook his head, and pointed at Zhang Yu.

Li Shengping actually knew, but since she pushed Zhang Yu out and let them get to know her, she naturally pretended not to know.

Tang Lao looked dazed, it shouldn't be, this question, with Li Shengping's current knowledge, it is just a very simple thing to answer.

Li Lao glanced at Zhang Yu, then at his granddaughter, and suddenly understood, picked up the teacup, took a sip quietly, and didn't say much, let them talk by themselves.

After Zhang Yu understood, he glanced at Li Shengping gratefully, but he didn't want to answer much, this question was just a very simple question, and it didn't mean anything to answer it.

"Zhang Yu, hurry up and tell Grandpa Tang about your cognition. Li Shengping saw that Zhang Yu didn't speak for a long time, so he hurriedly gave Zhang Yu a look.

Xiao Lao on the side put down the teacup and looked at Zhang Yu and Li Shengping, the two young people, you have one look and one look, and I suddenly understood.

"Shengping girl, since you want to introduce your boyfriend, let's just say it, don't make so many twists and turns, Old Man Tang, this guy, has a straight brain, and he can't turn around. Boss Xiao laughed and pointed out the words.

After seeing the performance of Li Shengping and Zhang Yu, he thought that the two were boyfriend and girlfriend, but he didn't expect Li Shengping to deliberately promote their relationship at this level.

"Oh! That's right! Old man Li, you didn't say it earlier, I was stunned for a long time. Old Man Tang heard Old Man Xiao's explanation, touched the back of his head, and reacted.

Zhang Yu touched his nose, a little embarrassed, it was a good introduction, but it turned out to be a boyfriend and girlfriend relationship.

"Grandpa Xiao, what nonsense are you talking about, Zhang Yu and I are just ordinary friends. Li Shengping hurriedly waved his hand to explain.

"Ah! Look at you one by one, make things more and more messy, let me, the old man, explain!" Seeing that the scene was a little chaotic, Li Lao cleared his throat and planned to raise all the questions.

But after thinking about it for a while, if Zhang Yu Xiaoyou really has something with his granddaughter, it is not impossible, thinking of this, when he came to his mouth, he stopped.

Zhang Yu and the others quieted down, and they wanted to listen to Li Lao's speech, but he fell silent.

"Old man Li, what the hell, what are you saying!" Old Li didn't speak for a long time, and the anxious Tang Lao asked.

"I'm just ordinary friends with Shengping, as for what Shengping meant just now, he saw that I didn't have a sense of existence here, so he gave me a chance to communicate. Seeing everyone's different expressions, Zhang Yu thought for a while and explained things clearly.

After listening to Zhang Yu's words, several people were relieved.

"Zhang Yu Xiaoyou, I will be the same as Li Lao, call you Xiaoyou, since we have talked about it here, let's continue to talk. Tang Lao glanced at Zhang Yu, and after a small episode, he became interested in this young man.

Judging from Old Man Li's performance towards Zhang Yu earlier, this young man seems to have something outstanding.

"Tang Lao is just casual, if you have anything you want to talk about, you can say it as much as you like. Zhang Yu smiled slightly and nodded.

"Zhang Yu Xiaoyou is also engaged in machine research, right?" asked Tang Lao.

Zhang Yu nodded calmly.

"What Xiaoyou has done so far, is it in the process of research, or has already achieved results. "Old Tang was very direct, took a sip of tea, and went straight to the point.

"The first product has been patented, and the remaining products are already preparing to apply for patents. Zhang Yu also took a sip of tea, put down the teacup lightly, and said his current situation.

"Oh!" Tang Lao whispered a word meaningfully, he was skeptical of Zhang Yu's words, you said that you have one or two patents, I really believe it.

But you say that you have a lot of products that have not been patented, which is a little suspicious.

For Tang Lao's obvious disbelief in words, Zhang Yu just took another sip of tea, and didn't say much, Li Lao knew his situation, and he had nothing to hide, as for Tang Lao not believing it, it was his business.

"Old man Tang, don't believe it, what Zhang Yu said, I have cooperated with him, but it is all genuine. Seeing Old Man Tang's puzzled expression, Li Lao explained a few words for Zhang Yu on the side.

"Are you serious?" Tang Lao glanced at Li Lao in surprise, if it was really as Old Man Li said, Zhang Yu, a young man, was really unusual.

"We've known each other for so many years, do you think I'm a joker?" Li Lao glanced at Tang Lao, and then motioned to Li Shengping on the side to pour him another cup of tea.

After Li Shengping added tea to Li Lao, he also added tea to Zhang Yu, and then added tea to Tang Lao and Xiao Lao.

Seeing this scene, these two old men were naturally unhappy, even if Zhang Yu really had some ability, they also wanted to give Zhang Yu a problem.

"If that's the case, Zhang Yu Xiaoyou is young and promising, so let's do it, I'm just engaged in this patent appraisal, why don't Zhang Yu Xiaoyou bring your product over, show me, and I'll apply for a patent for you." "There is something in Old Tang's words, waiting for Zhang Yu to enter the pit.

"That's it, thank you so much, Mr. Tang. Zhang Yu hurriedly made a gesture of thanks.

He was thinking about finding a time to apply for a personal patent with his own product, and here Tang Lao told him about it.

In response to that sentence, someone sent a pillow when he was sleepy.

"Zhang Yu Xiaoyou, let me make it clear to you first, some products with no practical value, even if they apply for patents, they are not of much value. "Tang Lao has been waiting for Zhang Yu here for a long time.

"Old man Tang......" Old Li on the side wanted to explain.

"Old Tang, I know that I won't get some things that have no practical value. Zhang Yu hurriedly opened his mouth and waved his hand to say that he would not do such a meaningless thing.

By the way, he also interrupted Li Lao's explanation, not that he didn't want Li Lao to explain, but that this old man was interested in coming to see, so he would leave him with a sense of expectation.

Li Lao also found that he had said too much, this was a matter between Zhang Yu and Tang Lao.
