Zhang Yu didn't pay attention to Tang Lao, who suddenly changed his attitude, and put his hands around his chest very calmly, he had already expected this scene, waiting for Tang Lao to continue to identify several of his other products.

"Zhang Yu Xiaoyou, what is the most important structure of your suspension plane, can you tell me about it?" After experiencing the vibration brought by the suspension plane, Tang Lao became interested.

"Trade secrets, Mr. Tang, you still continue your appraisal work, I just want to apply for a personal patent. Zhang Yu spoke in a cold tone, skipped Tang Lao's question, and returned to his own patent application.

Regarding Zhang Yu's coldness, Tang Lao just nodded, he didn't show anything, even if Zhang Yu was a little arrogant, this was also the attitude he should have, to invent such a shocking product is not something that anyone can do.

"Zhang Yu Xiaoyou, I'm a little excited, this suspension aircraft product, you give me the information, and I will apply for a personal patent for you when I go back. Tang Lao smiled and put down the hoverplane, signaling that this matter would be handed over to him, and Zhang Yu didn't have to worry about it.

"Then thank you Mr. Tang, and ask Mr. Tang to help me see if other products can apply for personal patents. Zhang Yu saw that Tang Lao's tone had changed, and he also let go of his coldness, pointed to a few other items, and waited for Tang Lao to check them.

Zhang Yu is such a person, if others respect him for three points, he will return three points to others, and if others attack him, he will inevitably return it.

"Multi-functional amusement equipment, with the effect of VR, its durability, and ......" Tang Lao looked at the introduction book given by Zhang Yu and read it out word by word.

He looked away in front, this time with the hoverplane in front, he naturally wouldn't be contemptuous, since Zhang Yu said that this product has this effect, it can't run 100%.

Regardless of the others, the particularity of the hoverplane alone can prove all this, and this is also the principle of their machine researchers, and the products they have researched should be what they are.

"I look at the structure of the parts here, and ask Zhang Yu how Xiaoyou designed it. Tang Lao looked up and down at the main parts of the multi-function, and did not rush to make a decision, looking at Zhang Yu with a puzzled face.

"Regarding the structure of the parts, I use an inbound method to protect the power operation system of the machine to ensure that the machine is not damaged, and at the same time ......" Seeing Tang Lao's friendly attitude, Zhang Yu also relieved himself and told him the detailed structure of his multi-functional amusement equipment.

Listening to Zhang Yu's words, Tang Lao nodded frequently, and the gaze in his eyes changed from shock at the beginning to appreciation now, and he felt more and more that Zhang Yu had a deep understanding of machine research, and he was simply a master in this regard.

"Wonderful, it's really wonderful, the old man's previous knowledge is still too shallow, and he still needs to study hard. Tang Lao's eyes were moved, and he sighed from the bottom of his heart.

"Tang Lao said with a smile, you are now one of the famous machine researchers in China, and you can't talk about learning, it's just some novel ideas. After Zhang Yu chatted with Tang Lao for a few words, the relationship between the two became familiar, Zhang Yu poured Tang Lao a cup of tea, motioned for him to sit down and speak slowly.

Taking the tea handed over by Zhang Yu with both hands, Tang Lao fell into a momentary distraction, his eyes looked directly at Zhang Yu, and he had a feeling of hating each other.

This is a kind of resonance between machine researchers, Zhang Yu and Li Lao met for the first time, after a discussion, as they learned about each other's attainments in machine research, there was a sense of sympathy.

"It's a pity that I don't stay in Binhai City often, otherwise I would definitely come here and let Zhang Yu Xiaoyou guide you one or two. Tang Lao took a sip of tea and sat down.

"Tang Lao's words are serious, guidance is not counted, let's just discuss it with each other. Zhang Yu waved his hand, naturally he would not follow Tang Lao's words.

There are advanced machine research attainments, this is only one aspect of technology, just technology, if you don't know how to be a person, you don't need to talk about a business empire.

"Zhang Yu Xiaoyou, do you already have an order buyer for these machines and equipment? Tang Lao put down the teacup and looked at the trace of heat floating up, and there was an imperceptible expression in his eyes.

Tang Lao and Li Lao, in addition to having considerable attainments in machine research, are also businessmen.

After all, if you want to better research products, if you don't have enough financial support, how to develop new products?

"It's all set. Zhang Yu nodded, his eyes flickered, and he heard the tone of Tang Lao's words, this is to talk to himself about business.

"It's an agreement with Old Man Li!" Tang Lao laughed strangely and asked casually.

"Mr. Tang, let's talk about my machinery and equipment applying for personal patents. Zhang Yu did not answer Tang Lao's words, but changed the topic.

These things related to business, it is naturally best not to mention them, they may not have the opportunity to cooperate in the future, what to say and what not to say, Zhang Yu is very clear.

"Zhang Yu Xiaoyou, you can rest assured, when I go back, the relevant certificates will not have to wait until tomorrow morning to arrive. Tang Lao took a sip of tea, and in a big tone, he showed that he was relieved to leave this matter to him.

"Then thank you Tang Lao here. Zhang Yu raised his hands to his chest, formed a fist with one hand, stood underneath, and made a polite gesture.

"I don't know if Zhang Yu Xiaoyou, has had time recently. Tang Lao's expression turned, his eyelids moved a few times, and he seemed to remember something.

"Lately, I haven't had anything too important, and there's plenty of time. Zhang Yu looked at Tang Lao with a puzzled expression.

"Since that's the case, it's even better, Zhang Yu Xiaoyou takes your products, how about we go to Yanjing?" Hearing Zhang Yu's words of affirmation, Tang Lao's expression was happy, and he excitedly said his purpose.

Because of the excitement of the words, he did not explain the matter.

"Old Tang, what are you doing in Yanjing. Zhang Yu touched the back of his head and asked directly about his doubts.

"But the old man I was a little anxious, didn't explain the matter, yes, not long after, Yanjing has a machinery and equipment exhibition, I see Zhang Yu Xiaoyou's products are good, to the exhibition can go to the exhibition, expand their knowledge. Tang Lao smiled and picked up the teacup, took a sip, and explained slowly.

"Is the Yanjing Machinery Exhibition that Grandpa Tang said the ten-yearly boutique machinery and equipment exhibition?" Li Shengping, who had been preparing tea next to him, listened to the conversation between the two and heard something, and looked at Tang Lao with a surprised expression, waiting for his affirmation.

"That's right, this boutique machinery and equipment exhibition is rare, it takes ten years to have one, and every time it is held, it will cause the madness of people in the machinery industry. Tang Lao nodded.
