For others, this point needs to be studied for a long time, which does not affect the balance of the aircraft, and can not affect the mass of the aircraft to reach the space flow speed, resulting in the inability to fly.

But under Zhang Yu's Luban craftsman's spirit, he can easily find that point.

When his craftsman enters the machine, he can analyze the machine thoroughly, and naturally he can easily find where to place it.

After finding the location, under the guidance of Lu Ban Craftsman, Zhang Yu placed the energy supply device, everything was done, took the suspension plane, and walked slowly towards the tea hall.

"Xiao Zhang, it's done so quickly. Li Lao said to Zhang Yu with a smile.

Zhang Yu nodded, put the levitation in front of Li Lao, and let him check it.

Li Lao pushed his reading glasses and carefully looked at this amazing product, whether it could really achieve the purpose of flying in the air for a long time as he said.

From the point of view of the principle of the machine, there is indeed no problem, but there is still a difference between reality and ideal, after all, there will always be various problems when the conceived things are applied to reality.

"Elder Li, if not, let me give you an experiment on the effect of this hoverplane, and you can take a look. Zhang Yu saw Li Lao's frequent nodding and knew that he recognized this hoverplane.

It's just that I haven't seen the effect of the hoverplane yet, and it's normal to have some doubts, in order to make Li Lao more convinced, Zhang Yu said this.

Li Lao looked at Zhang Yu, who was full of confidence, and nodded, he couldn't describe the young man in front of him in other words except admiration.

I don't know how this whimsical design was formed, but it was successfully designed and recognized by the majority of consumers.

Every engineering master who makes machine products wants his products to be recognized by consumers.

Several people came outside, Zhang Yu stood directly on the suspension plane, glanced at Li Lao, and then controlled the operation of the suspension plane.

With the effect of the energy supply device, there is no need to run on the ground to store energy, it is directly suspended in the air, and after flying into the sky, under the influence of air, the suspension aircraft does not need additional kinetic energy to achieve the effect of flight.

Li Lao and Li Shengping looked at this scene in shock, and sure enough, as said on the market, this hoverplane has the ability to fly.

In order to test the effect of the hoverplane, the ship had already stopped at this time, and Zhang Yu controlled the hoverplane to fly in the sky for a period of time, and then controlled the slow landing.

"Master Zhang, let's go in and talk. As soon as he landed, Li Lao's voice rang out.

It was only then that he understood the huge commercial value of this hoverplane, and it was true that he was an engineer, but he was also a businessman, so he would naturally not let go of this huge business.

Zhang Yu nodded, and several people returned to the tea hall again, without Zhang Yu talking to Zhou Yue, Li Lao preemptively said: "There is no problem on my side, if there is no problem on your side, take out the contract, and if there is something about the external market in the future, our Li family will cover it all." ”

Zhou Yue's expression was joyful, and he knew it from the moment Zhang Yu went to the studio to improve the levitation, just as they had seen Zhang Yu show the hoverplane for the first time.

"This is a contract, if it is Elder Li, you don't think there is any problem, let's sign the contract!" Zhou Yue took out the contract that he had been preparing for a long time.

Li Lao took the contract, looked at it, and signed the contract.

"Okay, the next thing is the delivery problem, when can you start handing over the goods, Mr. Li, on your side. Zhou Yue asked.

Generally speaking, after the contract is signed, Mr. Li needs to carry out a marketing promotion, and only after getting the response will he consider the issue of purchase.

"It's going to be handed over tomorrow, and I'll let my granddaughter arrange it now. Li Lao said lightly.

"In that case, I'll also arrange the delivery. Zhou Yue nodded and said, interested in Mr. Li's company.

This kind of order, in other words, their Ferris Group also needs one to two days to prepare, but Li Lao directly explained that he can arrange sales tomorrow, which is enough to see the great energy of their company.

Zhou Yue and Li Shengping went below to arrange the handover of the task, and only Zhang Yu and Li Lao were left on the tea table.

Li Lao looked at Zhang Yu in front of him with a torch of light, wanting to ask him about the machine.

Whether he only has a part of the ability, or does he know the entire machine industry, this is what Li Lao is interested in.

You must know that being proficient in so many industries, as long as you are willing to work hard to learn, you can achieve it, but you can be proficient in the entire machine industry, which is not just an effort, but more of an accumulation of time.

"Master Xiao Zhang, I don't know where you came up with the idea of designing this hoverplane?" asked Elder Li after thinking for a while.

"Oh, about the idea, it's ......," Zhang Yu replied.

"Then there is a study on the machine, what does Master Xiao Zhang think. After listening to this, Li Lao once again threw out a bigger topic.

"That's right, for the view of the machine, I think the current machine industry can be greatly changed, any machine parts can be sublimated, for example, the use of some parts, can be greatly changed. For example, the current amusement equipment is always broken, and I think we can change it, for example, ......"

Zhang Yu expressed his opinion, and by the way, he proposed his latest invention, multi-functional amusement equipment.

"Oh! How far has Master Xiao Zhang studied this multi-functional amusement equipment?"

For Zhang Yu's title, he has never been able to call Xiao Zhang, this is a common problem of these machine engineers, when they meet people who are more skilled than themselves, no matter how old they are, they will call them masters.

It's a respect within the industry for the convenience of proficient people.

"Now there is a finished product, but except that it is more perfect and durable than other amusement equipment, it has no characteristics, so it is impossible to open the market, so I plan to study it again. Zhang Yu did not shy away from it, and said the truth.

"There is no way to open the market, no! It depends on what industry, if it is some small industry, they naturally cannot afford to accept this product. Li Lao expressed his opinion.

Judging from Zhang Yu's statement alone, he knew that this multi-functional amusement equipment was not ordinary, how could it not open the market.

"Grandpa Li, are you saying that if the entire playground is contracted by one company, this machine will be of great practical value to them. Zhang Yu said as if he understood something.

After thinking about it carefully, I found that I had fallen into a misunderstanding, and I only wanted to hit the Chen Group's industry before, thus ignoring the commercial value of this product to other merchants.

If it is an integrated amusement business, this durable multi-functional machine is naturally conducive to their long-term development.
