If you go further.

For example, in areas more than ten light years away, the time cost is too high.

Then it must be used to reach one tenth of the speed of light.

But even one tenth of the speed of light.

Heading more than ten light years away.

It will take four or five hundred years.

It seems that it is much more difficult than imagined to become an interstellar civilization.

However, Su Han is now unable to get the ducks on the shelves.

Now I can only take one step at a time.

The best way is to dig out more helium three.

If helium three is enough.

At worst, some starts with working fluid mode.

Used in combination with working fluid and without working fluid.

Maybe the best solution.

...

Five more years passed soon.

Coming to 2052.

Four more warships were taken off the Mercury Base one after another.

Including three Jiaolong-class battleships.

It also includes a five million ton super battleship.

Su Han was very satisfied with this.

The new super warship uses dual power with working fluid but not working fluid.

However, dual power leads to insufficient part of the power.

And it also lost the ability to take off and land planets directly.

But for super warships of this level, take-off and landing planets also seem to be unnecessary.

If you take off and land a planet, you can just have that kind of landing ship.

Su Han named this five million ton warship the Demon Dragon Class 001 warship.

The total length of the Magic Dragon Ship is more than 5,000 meters.

There are hundreds of launchers covered with energy cannons on the ship.

There are also thousands of laser weapons.

More importantly, there is an electromagnetic weapon.

Although electromagnetic weapons are not as fast as laser cannons and energy cannons.

But powerful kinetic energy.

Make it have strong killing ability to target fixed.

...

Next is to test the new magic dragon ship.

The test was followed by Su Xinghe, vice president of the Academy of Sciences.

The Academy of Sciences can be said to participate in the construction of the Magic Dragon Ship.

Various supporting facilities and various fighter jets are also available.

It is no longer as shabby as the first dragon ship tested.

And the total number of people in the Academy of Sciences at this time exceeded 10,000.

New members join almost every year.

Su Han plans to create more new dragon humans in the future.

...

The test work of the Magic Dragon Ship began soon.

The magic dragon ship with hundreds of energy cannons.

The attack power is amazing.

The magic dragon ship can easily destroy asteroids of kilometer-sized size.

The power is naturally not comparable to that of the Dragon Ship.

Because the Magic Dragon Ship uses a dual-power system.

In the state of working fluid, about forty tons of helium three can accelerate to one ten thousandth of the speed of light.

However, in the absence of working fluid, this speed can be achieved in almost two months, but the fuel consumed is greatly reduced, just over one ton.

Whether it is time consumption or fuel consumption, Suhan is within the scope of tolerance.

Of course, this time the Magic Dragon Ship also tested other weapons.

The focus of testing is the electromagnetic gun.

This electromagnetic main gun uses large solid electromagnetic shells.

An extra-long conical shell can be accelerated to one ten thousandth of the speed of light.

Although the speed is not very fast, it carries more than one 10,000-ton nuclear bomb.

If the spacecraft flies at higher speeds.

The emitted electromagnetic cannon is faster.

The power will also be even more amazing.

However, the electromagnetic gun cannot guide it and can only attack fixed targets with slower speed.

Suhan tested near Ceres on the asteroid between wood and fire.

The shells finally hit Ceres at a speed of two-tenths of the speed of light.

A nuclear weapon explosion with a power of 20,000 tons.

Although this explosion is nothing to Ceres.

But it is enough to destroy a small city on Earth.

Su Xinghe then tested a new missile.

The new missile carries a 100,000-ton self-developed nuclear warhead, and the missile also carries kinetic energy devices.

Although the missile does not accelerate very quickly, the power of the spacecraft is still as high as the 150,000-ton nuclear bomb.

However, these tests are tested in a direction away from and deviating from the earth.

To avoid being seen by observation equipment on the earth.

Of course, there are some new fighter jets, mechas, dual-purpose landing crafts for planetary landing, etc. that are tested later.

Overall test performance.

Basically meet the standards.

Su Han, who felt that his overall strength was getting stronger and stronger, was also very satisfied.

...

The next step is to challenge the creation of a super mothership.

This mothership will become Su Han’s biggest capital for crossing the Star Sea in the future.

It can even be said to be the core of the entire dragon clan in the future.

No matter what, it must be of quality and quantity.

The key is to complete it within thirty years.

...

Su Han was already seventy-five years old at this time.

The company's affairs are basically ignored.

Almost all of them were handed over to their children.

But he did not retire either.

He is still responsible for the affairs of Haohan Company himself, and he is still busy with work every day. On the surface, he has devoted all his energy to the construction of Mars City.
