The correct way to open the sprite

Cromwell said: "Cut off the Lengshui River, let the river water seep into the wilderness, and turn this barren land into a new oasis. I didn't believe it when Darren told me before, but I didn't expect that people would do this. "

Ives asked doubtfully: "Teacher, do you think it can be successful?"

"I don't know whether it can succeed, but I know that this dam can definitely do more than that. Right, Zhizhi?"

"Well, Teacher Darren said that the core of this project is over there." Weizhi said and pointed to a row of houses nearby.

"What is that for?"

Wei Zhi shook her head: "I don't know, I haven't asked Teacher Darren."

Cromwell said: "I know this, it is used to generate electricity."

At the mention of electricity, the three top human beings sighed again. They still haven't understood what it is.

They had also studied it secretly, but after sacrificing the life of an envoy soldier, their research on touching wires with bare hands turned into practicing their eyesight in front of light bulbs under street lights.

Malphite, the Great Earth Mage of the Brocade Empire, said something unclear: "Oh, I don't know if it's good or bad."

Except for the little girl Wei Zhi, Ives and Cromwell are all mature and mature, so they can't hear the hidden meaning in his words, but they can only hear it.

To this day, the existence of Cattail City has done more good than harm to the human world. Whether it is Cattail City providing a large number of weapons to the human world, or Cattail City single-handedly suppressing the Bone Gate in the underworld, it is harmful to mankind. These are very rare benefits.

But no matter what they think, it has nothing to do with Feng Yu.

The dam project has entered the main construction stage. Feng Yu has been keeping an eye on it these past few days. Today there is one more person around him, and that is Dempsey, who rarely comes out for a walk.

The Fortress of the Gate has become the home of two great elf magisters. They need to stay there permanently to deal with emergencies, but they also take turns to come out for activities and interactions.

Dempsey said with emotion: "I thought that the construction of the Gate Barrier was already a big event, but I didn't expect it to be comparable to this dam."

"This project is troublesome with interception and dredging. The basic engineering is in place, but actually building the dam is quite simple. Because of the high demand, we directly connected the concrete pipeline to pour the entire dam.

If it weren't for the characteristics of the concrete that needed to be considered, the pouring would have been completed by now. "

Feng Yu gestured and said: "When the time comes, fill in more soil on both sides of the dam and bury the dam, and it will be basically foolproof."

Dempsey said with a smile: "Then what are you going to do next? You kid can never be idle."

Feng Yu looked up to the east and said, "Next, let's march into the desert and complete all the major scientific research projects for him."

"Are we finally going to take this step?" Demps asked.

Feng Yu nodded: "Time waits for us. Besides, if we don't do it, the elves will never be ready. As long as you and Mr. Anthony don't collapse, everything else is not a big problem."

Dempsey laughed loudly: "Instead of worrying about me, you should worry about Anthony. I am much more open-minded than him. But having said that, you are really sure that you will not offend some beings by doing this."

Tell the truth, have you ever done this kind of thing?"

Feng Yu spread his hands and said: Those who are skilled in various postures are welcome. "

“Although I don’t want to believe what you say, my reason tells me that everything you say is true.

To be honest, I'm looking forward to it. I want to try something that all previous Dharma Saints in Green have been unable to do. "

Feng Yu said with a smile: "Then you should urge your daughter more, Nitya is also involved in the rocket engine project."

With the development of Xiangpu City's technology, Feng Yu's role in other fields has become more and more important. He has also gradually shifted his work to the software field in which he is good at.

The size of Cattail City has caused a distortion in the development of science and technology in Cattail City. The laboratory of the Academy of Sciences has built a radial engine with good performance. The Soul Fire Laboratory is even collecting data to compile aircraft design software suitable for aerodynamics. But Apart from airships, Cattail City doesn't even have an ancient biplane.

After all, the purpose and combat capability of the airship were limited. Feng Yu finally couldn't stand the slow airship and forcibly transformed the airship design team into an aircraft research and development team. To put it bluntly, he no longer invested energy in the airship, but turned his head. Start making planes.

Feng Yu could only take the lead again and join the newly transformed aircraft team.Although this was not his field, he first had to let the entire team understand what an aircraft was before he could let them develop and improve it themselves.

In fact, with experience in the design and manufacturing of airships, it is easy to build a simple aircraft. After all, airships and aircraft have something in common regarding rudder steering control and the like.

There are propellers on the airship, rudder control on the airship, and various instruments and equipment on the airship. Cattail City's industrial manufacturing capabilities that are not found on the airship can also be fully manufactured.

In this way, in less than a month, Feng Yu was forced to command the airship team and built a single-wing propeller aircraft.

Because the power was sufficient, Feng Yu did not use any double wings, but followed the design ideas of the classic propeller fighter of World War II in one step. As for the details, he would just modify them slowly.

As for whether there are design deficiencies, don't think about it, there must be many, many.

As for whether it will fall off and crash into the plane during testing, don’t think about it, that’s for sure.

The aircraft testing ground in Cattail City is on the edge of the Dadongbian Desert. Here, the railway line to Golden City was diverted and a simple airport was built.

As for why we went so far to build an airport, it's because planes that fall into sand dunes can basically retain their structural integrity and are better suited for finding errors.

Moreover, there are few people here, so it won’t be too embarrassing if the gadget you made falls off.

However, Feng Yu still underestimated curiosity. When the gadget he created was brought to the newly flattened runway for experimentation, a large number of spectators followed him.

There's no way around it. Anyone can take a look at the iron lump that can fly even without an airbag.

The key is that Feng Yu boasted so much about this thing before that he could barely compete with Cromwell, the wind magic saint, in the air. How could everyone not be curious.

Looking at the busybodies surrounding the runway, Feng Yu suddenly felt so tired that he had already come here. If he didn't let this guy fly today, wouldn't this science and education film become a sitcom?
