After letting Yang Ruolan accompany her parents and others to play in the capital for two days, Xu Ziling and the elders apologized and took Li Chenggong to the airport to return to Star City.

The straight-line distance from Beijing to Star City is less than 2,000 kilometers. At the speed of Gulfstream 550, it takes more than an hour.

After getting off the plane, Xu Ziling entered the office immediately.

"What's the situation? Tell me."

"Aren't you free these days? I thought of this when I was bored that day, so I have been thinking about it these days. But I didn't expect that I would actually find a solution to the problem. Come on, take a look.

…”

The reason why an ion engine cannot be built is because ions are uncontrollable. According to current technology, it will be impossible to produce the required materials to make ions controllable within at least ten years.

Xu Ziling immediately took the information provided by Lion and read it over, and then he understood why Lion said he could make the engine:

After testing tens of thousands of various high-strength alloy materials, he finally found an alternative material. According to the current level of technology, this material can be produced, but the cost is a bit high.

With a diamond mine and large oil fields, as well as the profitability of the group itself, the most important thing for Red Star is funds. As long as they can produce an ion engine, they can afford the high cost.

I was quite excited: "In other words, as long as the gravity problem is solved now, our aircraft can enter space?"

"Yes, that's it." The lion was equally excited. For him, space has an unusual allure. Once an airplane can enter space, even if it can only fly short distances for the time being, this will be a considerable progress.

Second, by working hard to develop on this basis, one day he can truly enter the space age. Once that happens, maybe he can go back to the place where he was born.

"Then when will the gravity problem be solved?"

Xu Ziling is very concerned about this issue. After all, even if there is an ion thruster, if the gravity problem is not solved, it will be no different from the current space shuttle. It is useless. It just doesn’t need to be launched with a rocket!

"Two years, absolutely no problem." The lion's answer was decisive.

"Okay." Xu Ziling laughed, "From now on, you can solve this problem with peace of mind, and let go of other things that can be left to others. Solving the gravity problem is a great achievement."

Gravity technology is not only used on spacecrafts. It has a wide range of uses, such as testing aerospace equipment, creating a livable environment for future alien immigrants, etc...

In other words, once this problem is solved, living in space or on alien planets will no longer be a dream.

"That's no problem, but you have to work hard on the materials yourself. I believe this won't be a problem for you."

Xu Ziling nodded. A few months ago, he had the idea to launch a spaceship project. He had already started working on issues related to spacecraft materials. He had already memorized many of the spaceship optimization plans in the Lion system. As for the most important issue of materials,

, already understood.

"Two years, no problem at all."

"Okay, let me solve the gravity problem in two years and you solve the material problem. Then we can build a miniature spacecraft to try. I believe it will be no problem to go to the moon."

…

Starting from the next day, Xu Ziling transferred some people from the laboratory to be responsible for the ion thruster project. Because there is an engine laboratory, and the ion thruster is also an engine, the related tests are much simpler and do not require too many special tasks.

The world's first true ion engine was launched in just one month without the need to build a separate site.

"Is this the surprise you were talking about?"

When the engine was moved out of the laboratory, Yang Kaiming came back after his wedding leave. "This seems to be an engine?"

Li Cheng has been with Xu Ziling these days, and understands the importance of this thing that is not much different from an ordinary engine. Xu Ziling does not need to explain, he said: "This is an engine, but you know what kind of engine it is."

?”

Although the words were in a questioning tone, he was too "showy" and continued without waiting for Yang Kaiming's answer: "This thing is used as an engine for spaceships. Does the spaceship know about it? This means that we can build spaceships in the near future."

"Ah..." Yang Kaiming opened his mouth wide.

He had no idea that the thing in front of him was actually used on a spaceship.

Even though he had seen a spaceship before, he still couldn't believe it when he found out that the engine in front of him was used on a spaceship.

I had asked Xu Ziling before that it would be impossible to get the spaceship within twenty years, but it had only been a few months since I asked this question...

No wonder he wasn't surprised.

"Didn't you say it couldn't be done within twenty years?" Surprised, he looked at Xu Ziling doubtfully.

Xu Ziling smiled and shook his head, "It's not what you think. Chengzi didn't explain it clearly to you. The spaceship we are talking about right now is a micro spaceship. Even if the technology matures to a certain extent, landing on the moon is the best result.

It's not like the big spacecraft we were talking about last time for space flight."

Having said this, he paused and said, "There were some mistakes in our previous predictions. Originally, we couldn't produce this kind of engine for the time being. But a few days ago, by chance, Lion found a replacement engine.

Only in this way can the materials be produced in advance, otherwise, it would take who knows how many years to produce such a small spacecraft."

After hearing his words, Yang Kaiming's happy expression immediately appeared, and he clapped his palms gently, "In other words, this time it is the lion's credit? Good job, lion."

The lion was busy solving the problem of gravity when he popped up and said hello to Yang Kaiming before disappearing.

"Then when can we get the spacecraft? I really want to see the moon." Yang Kaiming asked again.

Xu Ziling thought for a while, "If it's a space shuttle, we can build it in less than half a year. But for us, it doesn't make any sense to spend so much time to build such a useless thing, so I just want to build it."

One thing, I already have a plan these days to build a brand new micro-spaceship, which will definitely not be like the current spaceship where eating and going to the toilet are a hassle."

Yang Kaiming immediately understood the meaning of his words and was surprised again, "Does that mean you can solve the gravity problem?"

Nodding, Xu Ziling answered him truthfully: "Yes, this technical problem will take about two to three years. At the same time, other problems such as fuselage materials will also be solved. In other words, we will take at most five years.
