If traveling further afield.

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

Then you have to reach a tenth of the speed of light.

But even a tenth of the speed of light.

Travel more than a dozen light-years away.

It will also take four or five hundred years.

It seems that becoming an interstellar civilization is far more difficult than you think.

However, Su Han is also chasing ducks to the shelves now, and there is no good way.

Now I can only take one step at a time.

The best thing to do is to dig more helium-three.

Helium three is enough.

The big deal is that some of the startups have working fluid mode.

It is used in a combination of working fluid and non-working fluid.

Maybe that's the best solution.

……

Fast forward and another five years.

It's 2052.

Four more warships rolled off the assembly line at the Mercury base.

Including three Jiaolong-class warships.

It also includes a five-megaton super-warship.

Su Han was very satisfied with this.

The new super warship adopts dual power with and without working fluid.

However, the dual power led to a partial lack of power.

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

But for a super battleship of this class, it seems that there is no need to take off and land planets.

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

Su Han named the five-million-ton battleship the Demon Dragon-class 001 battleship.

The total length of the dragon ship is more than five thousand meters.

The hull is full of hundreds of launchers filled with energy cannons.

There are also thousands of laser weapons.

More importantly, there is also an electromagnetic weapon.

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

But strong kinetic energy.

Make it powerful against stationary targets.

……

The next step is to test the new Magic Dragon Ship.

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

For the construction of the magic dragon ship, the Academy of Sciences can be said to be involved in the whole process.

All kinds of supporting facilities and all kinds of fighters are also readily available.

It's not as shabby as it was when the first Jiaolong ship was tested.

The total number of students in this academy is more than 10,000.

New members join almost every year.

Su Han plans to create more new dragons in the future.

……

Test work on the Magic Dragon Ship soon began.

A dragon ship with hundreds of energy cannons.

The attack power is very amazing.

The Dragon Ship can easily destroy kilometer-sized asteroids.

The power is naturally not comparable to the Jiaolong ship.

Since the Magic Dragon ship uses a dual power system.

In the presence of working fluid, about 40 tons of helium-3 can accelerate to 1/10,000th of the speed of light.

However, in the state of no working fluid, this speed can be reached in almost two months, but the fuel consumed is greatly reduced, as long as more than one ton.

Whether it is time consumption or fuel consumption, it is within Su Han's affordability.

Of course, this time the dragon ship also tested other weapons.

The focus of the test is the electromagnetic gun.

This electromagnetic cannon uses solid large electromagnetic cannonballs.

It is possible to accelerate an extra-long cone-shaped shell to 1/10,000th of the speed of light.

Although the speed is not very fast, the kinetic energy it carries exceeds that of a 10,000-ton nuclear bomb.

If the ship is flying at a higher speed.

The cannon is faster.

The power will also be even more amazing.

However, the Cannon cannot be guided and can only attack stationary targets that are slower.

Suhan conducted the test near Ceres on the asteroid between the wood fires.

The cannonball eventually hit Ceres at 2/10,000th of the speed of light.

The power is equivalent to the explosion of a nuclear weapon of 20,000 tons.

Although this explosion is nothing to Ceres.

But enough on Earth to destroy a small city.

Subsequently, Su Xinghe tested a new missile.

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

Although the acceleration of the missile is not very fast, with the speed of the spacecraft itself, the power of the nuclear bomb still reaches the level of 150,000 tons.

However, these tests are conducted in a direction away from and away from the Earth.

so as not to be seen by observation devices on Earth.

Of course, there are also some new fighters, mechs, and dual-purpose landing craft for planetary landings that will be tested later.

Overall test performance.

Basically up to the mark.

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 supercarrier.

In the future, this mothership will become Su Han's biggest capital to cross the sea of stars.

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

In any case, quality and quantity must be guaranteed.

The key is to do it in thirty years.

……

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

The company's affairs are basically gone.

Almost all of them were given to their own children.

But he also did not retire.

He is still personally responsible for the affairs of the vast company, and he is still busy working every day, and on the surface, he puts all his energy into the construction of Mars City.

The daughters know it too.

Su Han attaches great importance to the construction of Mars City.

Naturally, there is no way to intervene too much.

But since Su Han delegated the company to his children.

The company's technological development has basically come to a standstill.

But fortunately, these people can't fight the country.

It's okay to defend the country.

The company is also well managed.

Among Su Han's children, only Su Lianwu is not married.

Su Han didn't have a problem with that.

Everyone has the right to choose their own life, including their sons.

Although Lian Shanshan was unhappy, she couldn't control it.

Fortunately, another Su Lianwen gave birth to a grandson.

Let her mood be a little better.

……

At this time, countries around the world have also entered a period of stability.

After Su Han retired.

Longhan Technology suddenly lost the impetus for innovation in the field of science and technology.

China's economic growth is also somewhat sluggish.

It seems that people just knew.

The importance of a good leader and scientist.

But the problem is that Su Han is seventy-five years old after all.

It can only be said that no matter how awesome the genius is, he will eventually grow old.

But Su Han is for the whole of China and the whole world.

Destined to be a legend.

……

Although the economy of China is not growing.

But it is still the world's largest economy.

The total economic volume is still very impressive.

Huaxia's greatest achievement is, of course, the construction of Mars City.

After nineteen years of construction.

The size of Mars City has reached 100,000 people.

Although Su Han seems to have spent a lot of manpower and material resources in order to build Mars City on the surface.

But the overall speed of Mars City's advancement was not as fast as expected.

A lot of supplies have to be transported from the earth.

So you can think of wasting most of your time on the road.

This is the result that Su Han wants to see.

Anyway, the construction of the entire Martian City.

It's basically under his control.

And the rest of the world will focus on the development of the moon.
