200 million tons of objects, if this were placed on the earth, there would be no way to move it except for the earth itself.

Of course, there is no other object on Earth that can reach this massive mass except Earth.

But in space, 200 million tons is nothing, not to mention the eight planets in the solar system, there are millions of asteroids here in the asteroid belt, just find one, and its mass is also calculated in 100 million tons.

"0.2 standard power, which means it can only propel 200 million tons of asteroids."

Qin Yi silently calculated in his heart, the 'Qinglong' spaceship Qin Yi is mainly used to go to the asteroid belt to mine asteroids, and then use the asteroids to smelt directly in space to create large overall castings and create more powerful spaceships.

"It's still too weak, only 200 million tons of thrust, and at most it can tow back about 100 million tons of asteroids at a time."

Qin Yi couldn't help but shake his head, the powerful power of this second-generation anti-gravity engine couldn't be exerted at all.

"Take your time, when our space smelter is built, we can cast the whole casting, and then we will be able to give full play to its powerful power."

"How can it be so easy, even if it is a casting of the whole casting, there is no way to say that its powerful power can be fully exerted, we still need to work hard in terms of basic materials, and research more powerful materials."

"This is true, materials science is a basic discipline, almost determines the height of many industries, we have not been able to build an ideal engine for aircraft engines before, a large part of the material problem."

"I heard that the Institute of Materials Science has developed a lot of new materials, and I don't know if there is one that can suit us, so I will definitely go back and have a look."

Several people are discussing with each other in the virtual world, because it is in the virtual world, the communication between several people can be regarded as using brain waves to communicate, and the speed is very fast.

Here, with the arrival of Qin Yi, the entire huge 'Dragon's Nest' space factory has also begun to officially start.

The size of the 'Blue Dragon' spacecraft is really too big, it is definitely the largest spaceship ever built by mankind, and to build such a huge spaceship, it is not just as simple as an engine.

From the overall design of the entire spacecraft to the design of every detail, this is definitely a very huge project, and Qin Yi also mobilized more than 100,000 scientists and engineers on his side, which took nearly a year, and the design drawings alone are enough to fill several rooms.

I saw an anti-gravity spaceship slowly approaching the huge 'Dragon's Nest' space factory from the void, and soon, it was moored to the berth.

The huge hatch slowly opened, and the mechanical arm began to carry out the long steel bars inside the spaceship, each of which was 20 meters long, 50 centimeters thick, and one meter wide, which was used to lay the keel of the 'Blue Dragon' spaceship.

Each steel bar is individually customized to the steel bar enterprise, and there are designed inlay notches at both ends, so that when each two are connected together, they can be perfectly connected together.

The robotic arm transports the large steel bars to the dock where the keel is made, and then begins laying the keel of the Blue Dragon spaceship.

Qin Yi, Yang Hongyan, and Zhang Jian naturally did not miss this moment, and came to the dock where the keel was laid early.

The trio wore spacesuits and sat on top of a chair that had a mechanical arm that could be extended, and only needed to be controlled by a virtual machine, and the person sitting on it could move quickly around the dock.

Of course, in space, because there is no gravity, it is natural to talk about whether to sit or not, and the main role is to fix and move quickly.

At this time, many scientists and engineers, like Qin Yi, wore spacesuits one by one and came to the place where the keel was laid with the assistance of the mechanical arm, wanting to see all this clearly.

I saw that the two steel bars were slowly spliced together under the control of several mechanical arms, and the two steel bars were connected to the mortise and tenon structure at the ports.

This is not easy, as the gap is so small that it is difficult to see with the naked eye, which requires a very high level of finishing, and the connection between the two steel bars must be machined to the point where the error is as small as a few wires.

It is not difficult to do this if it is a very small component, and the lathe technology on the earth is very mature, and the enterprises that process it to this extent are still grasping a handful.

But this steel bar is 20 meters long, one meter wide, and 50 centimeters thick, and it is not easy to process such a large piece of steel to such a large level.

Galaxy Technology Group has spent tens of millions of Chinese dollars on each steel bar, a large part of which is because the difficulty of this processing is too great, and each steel bar is customized.

The reason why it took such a huge price to build the keel was because the power of the second-generation anti-gravity engine was too powerful, and if the spaceship did not have a strong keel to support it, the engine would be enough to tear the spaceship apart.

The so-called shipbuilding first makes bones, only under the premise of having a strong keel can build a powerful ship, whether the ship is a ship sailing in the ocean, or a ship used to fly in interstellar space, it is the same principle.

The two keels are connected together, using the mortise and tenon structure, and a nail needs to be nailed at the joint, of course, this nail is also custom-made to fix the stressed things.

After ordering this nail, the two steel bars were completely connected, and a long stick with a length of 40 meters was walked, but this was only a part of the keel.

The mechanical arms began to be busy, and the steel bars were constantly transported, and they began to be connected continuously under the control of the mechanical arms.

Two months later, a large keel appeared in the keel dock.

The keel of the spaceship is different from the keel of sailing in the ocean of the earth, the keel of sailing in the ocean, it is only half of a sphere, and the keel of the 'Qinglong' spaceship, it is a whole, forming a complete ring, which is almost equivalent to the keel of two ships sailing on the earth's ocean.

"Finally the keel is made, the next step is to add flesh and blood to it~"

Wearing a spacesuit and with the help of a robotic arm, Yang Hongyan walked through this huge keel, carefully inspecting every part of the keel.

The keel is good or not, this is directly related to everything of the spaceship, the keel accepts, the bearing capacity is strong, and it can naturally better play the strong power of the second-generation anti-gravity engine, on the contrary, if the keel is not good, there is naturally no way to play a more powerful power.

And power is everything that determines the spaceship, only with strong power can it fly faster, with more powerful transportation capacity, power determines the value of the spaceship.
