And those technologies that have successfully upgraded the intermediate technology list.

Advanced has been enabled.

Advanced skills also require money to enable them.

But compared to the trillions of intermediate levels.

Each category of advanced skills requires at least tens of trillions of dollars.

Even the nuclear industry requires tens of trillions of dollars to be successfully launched.

Su Han made a simple calculation.

If you want to upgrade all your skills to advanced level.

At least four trillion yuan is needed.

This is equivalent to 70% of the current GDP of China.

Although it's exaggerated.

But it is still within Su Han's tolerance.

No matter how much it costs anyway.

Su Han also wants to upgrade the technology in his hands to advanced level.

Because it concerns whether you can survive.

...

Then something shocked the world.

Su Han decided to donate 4 million yuan to the country.

This number can be said to have scared everyone in the world.

Although everyone knows that Su Han is very rich.

But how much money does Su Han have?

No one knows.

However, according to professional media forecasts, if fixed assets are not included.

Su Han has at least one trillion cash assets.

Because Su Han donates at least one trillion yuan per time.

Sometimes even donate trillions of dollars at once.

The money is not enough for him to donate.

But no one expected that Su Han could donate four trillion yuan at once.

This is too exaggerated!

You should know that the total amount of social security funds in China is only tens of trillions of dollars.

Su Han donated ten social security funds at once.

This donation is a bit exaggerated!

Although it was said before that a person was particularly rich and even rich enough to rival a country, it was just a matter of saying that.

Now, there is a top five richest person in the world including fixed assets, including 180 billion meters of gold.

But now it seems that the money of the top 1,000 rich people in the world is not as much as Su Han’s cash.

I have to say that Su Han is already rich enough to compete with the world.

This guy is too rich!

The key is whether four million billion is Su Han’s bottom line?

Su Han can't donate all his money like crazy!

If Su Han still has money.

Then Su Han's wealth is absolutely unimaginable.

The global issue of how much Su Han is worth has also become a hot topic around the world.

...

Su Han didn't care about this.

He donated only to gain more knowledge.

Even if you donate all the money.

For this knowledge.

He must do that, too.

Because aliens are about to attack the earth.

In any case, he had to run away before the aliens came.

As for helping the earth resist aliens.

It's no longer in his choice.

If you decide to stay on Earth, you will be immediately turned into an idiot by the system.

What's more, even if you can stay on Earth, you may not be able to fight these aliens.

Because these aliens can come to Earth in just a few decades.

It can be seen that its technological advancedness is far beyond that of the earth.

Even if I stay here, I will die.

The best way is to listen to the system and run quickly.

The massive amount of knowledge obtained after donating instantly filled Su Han's brain.

During the period, various black technologies emerged one after another.

What Su Han is most concerned about is knowledge in the aerospace field.

What surprised Su Han was that there was actually nuclear fusion engine technology in the new knowledge system.

And it is also a legendary engine without working fluid nuclear fusion.

Traditional engines are all engines with working fluid.

This working fluid engine uses the material injected backwards when the fuel is burning, forming a reaction force to push the spacecraft forward.

However, the working fluid-free engine can generate reaction forces without using any fuel, so the efficiency is naturally not comparable to that of the working fluid engine.

Originally, there were no working fluid engines in recent years that were once considered a scam.

Because some scientists have discovered that the so-called working fluid is actually the magnetic inductive line of the earth that has been cut, and the thrust generated.

So there is no so-called working fluid-free engine at all.

The working fluid-free engine also became a civil science and technology overnight.

It has become a technique that everyone calls for.

Su Han once believed that no working fluid itself did not exist.

But the new technology obtained in Su Han told him that no working fluid exists.

Although there is no working fluid here, it is still cutting magnetic inductance wire.

But it is not the magnetic inductive line that cuts the earth.

The sun itself also has a magnetic field.

Moreover, the magnetic fields between different star systems also affect each other, and even the Milky Way itself has magnetic fields.

It’s just that the earth’s magnetic field is too strong.

Ignore other magnetic fields.

As long as someone can increase the power of the engine large enough.

Then it can also cut into other stars, even the magnetic inductance lines of the entire galaxy, and then it will also produce a working fluid-free effect.

If a super large and fusion device can be produced.

Then you can convert a massive amount of electrical energy into microwaves, cut the extremely weak magnetic inductance lines of the star, and finally generate thrust.

The greater the power generated.

The stronger the thrust.

Although a working fluid-free engine also consumes fuel.

But compared with working fluid engines.

The working fluid-free engine is more fuel-efficient.
