Although there are many volcanoes, there are still relatively stable places.

Suhan set up temporary mining farms in these places.

The latest production of a large mineral processing ship is also docked in the orbit of the Prisoner B.

The minerals are transported to the mine ship via a space elevator for further processing.

Finally, it was transported back to Prisoner Ox C for the production of warships.

……

Su Han already has one hundred and thirty dragon ships.

Twenty-six dragon ships.

Four Qinglong ships.

and a 50% progress of a mothership to be built.

In addition to combat ships and carrier ships.

And all sorts of messy battleships.

The experimental ship specializes in various experiments.

Mine ships are used to refine various minerals.

The biological ship is used for the cultivation and production of various animals and plants.

Although there are many battleships of the dragon clan, it is still not enough to put all the people on the battleship.

Because the population of the dragon clan has now skyrocketed to 50 million.

It seems that the rate of population growth is much faster than the growth rate of warship construction.

……

The first generation of reformers had all passed away by this time.

It also represents the original generation that has left the earth.

Say goodbye to this world completely.

Although Su Han was in a very bad mood.

But what is born and dies is not something he can influence.

But the first elite of the Academy of Sciences died before they died.

All of them were stored by Su Han in the anesthesia cabin of the Shenlong.

I hope that there will be a breakthrough in science and technology in the future.

There is still a chance to recover this group of people.

……

The Ten Bases of Prison Bull i3 have also been built.

The orbital dockyard has also begun to officially put into production for the construction of ships.

I believe it won't take many years.

The population of the dragon clan can exceed 100 million.

……

Just when Su Han felt that everything was going in a good direction.

Shenlong suddenly said: "Boss! I found something that looks like an alien spaceship. ”

"What!" Of course, Su Han was shocked when he heard this!

The current Su Han was also bitten by a snake once, and he was afraid of the well rope for ten years.

It seems that he is an alien civilization, and he is already a bird of shock.

Among them, what he feared the most was that he had encountered an alien civilization before and chased after him.

Su Han hurriedly said: "You mean aliens!" Are they the same aliens who once hunted us down in the solar system? ”

Shenlong said: "It's hard to say! I haven't seen any of those aliens. And it's just a suspected alien spaceship! The ship is now only fifty percent of the speed of light. The alien spacecraft that is chasing us is 95 percent of the speed of light. I don't know if it's a bunch of aliens. ”

Su Han was stunned! "Then how are you sure that this is also an alien spaceship?" ”

Shenlong said: "Unless it is a man-made object!" Otherwise, it would not be possible for something in nature to reach fifty percent of the speed of light. ”

Su Han thought about it and said hurriedly. "Let me see!"

A holographic projection appeared in front of Su Han.

There is a clear star field map all around.

One of the dots flickered and flickered.

The front end of the dot.

There is a dotted line facing the direction of the Bull Prisoner.

"This thing is a suspected alien spaceship?" Su Han pointed.

Shenlong said: "Yes! ”

Su Han said: "How big is this thing?" ”

Shenlong said: "From the analysis of the coverage area of the gravity field, the volume is more than 500 kilometers, and the mass is about 50 billion tons. ”

Su Han was stunned! frowned: "There is a problem with your data!" With a volume of more than 500 kilometers, how can it be only 50 billion tons? There are dozens of trillion tons of them! ”

Shenlong said: "The volume and mass of this object are observed through the gravitational field, and it should not be wrong. It stands to reason that something as big as it should not be so light. So this thing should be hollow, so it doesn't have that much mass. ”

"Hollow!?" Su Han pondered...... A hollow thing five hundred kilometers in size is flying at fifty percent of the speed of light.

Say this thing isn't an alien spaceship!?

I don't believe it myself.

But the problem is a five-hundred-kilometer spacecraft.

It's already one-seventh the size of the moon.

That's an exaggeration, isn't it?

Thinking of this, Su Han suddenly felt a little big.

Su Han said: "Are you sure this suspected alien spaceship is coming towards us?" It could not be that they were planning to go somewhere else? ”

Shenlong said: "We are now at the edge of the galaxy!" There are simply no other stars behind it. Unless they want to leave the galaxy. But at their speed! Even traveling to the nearest galaxy would take hundreds of thousands of years to arrive. So it's very likely that they came to the Prison Cow Galaxy. Of course, it is not excluded that they may be adjusted in the future. It's hard to say yet! ”

Su Han was also a little speechless!

I don't know why I'm so unlucky.

On Earth, he was chased by aliens.

It didn't take long to find a safe place.

I met aliens again.

The aliens have all caught up with the market.

Why is it everywhere?

Su Han said: "You too! How did you find out about these aliens? ”

Shenlong said: "It can only be said that it was a coincidence!" It was supposed to be as planned. I need to organize the surrounding star charts on a regular basis. But on the side of the Astronomy Center, it has been occupying the Eye of the Dragon all these years. Recently, the Eye of the Dragon has just been idle. And this suspected alien spacecraft happened to be within the sensing range of the gravitational field again. If you change the time period, you may just miss it, and it will be a real problem. ”

Su Han was a little annoyed and said, "Really! The Dragon's Eye isn't a big deal either. There should be a few more. But it's useless to talk about it now! By the way, how long will it take for this alien spacecraft to reach Prisoner Bull? ”

Shenlong said: "At its current rate, it will take about thirteen years. ”

Su Han said: "Thirteen years! It should be enough for us to complete all the ships and run away together. ”

Shenlong said: "I'm afraid it's difficult!" ”

"Why do you say that?" Su Han asked.

Shenlong said: "If we use all our production capacity to build carrier ships now. It will take about eight years. Then all that remains is five years to escape. If the working fluid state is used, it will probably take more than four years, less than five years, to accelerate all warships to 30 percent of the speed of light. Although the enemy is still some distance from us. But the problem is that our fleet has reached maximum speed. If fuel continues to be used for acceleration, there will not be enough fuel for deceleration in the future.

If a nuclear bomb is used to accelerate.

Then the number of nuclear bombs we have now is not enough to support such a large fleet to accelerate and slow down. And it's too obvious to accelerate with a nuclear bomb! It's like a searchlight. ”

Su Han said: "Then what do you mean! We can't run even if we want to? ”

Shenlong said: "Not really! Unless we first accelerate the fleet to thirty percent of the speed of light. Then all the fuel on the combat ship was transferred to the carrier ship.
