Marrow Jack's face was gloomy and struggling.

Ye Fan ruined his life.

He also wanted to ruin Ye Fan's plan.

It's just that if he destroys Ye Fan's plan, he will become a sinner for all mankind, and it will also lead to the failure of this plan, and the complete destruction of mankind, will he really want to be a sinner for the ages?

Scold!

My own life is gone, sinners through the ages, that is also fame!

Mallowjack, who had a headache, simply didn't think about it.

He's waiting.

If the officials don't look for him, then he really has to do it.

....

Another half a month has passed in a hurry.

Ye Fan's laser machine tool has also been fully laid, so that the speed of producing diamond drill bits can be greatly increased, from the previous daily production of two diamond drill bits to the current daily production of fifty diamond drill bits, this speed change, is already flying.

And those scientists have just learned something.

It is still very difficult to learn this technology, but they can already do it if they only need to produce these laser machines, after all, they have learned knowledge.

With their help in production, Ye Fan didn't care much about diamond drill bits.

Now all the directions of Ye Fan are the ion engine.

The core of the ion engine, the flint ignition device, has now Ye Fan also produced thousands of them, and it is far from continuous, at least a hundred thousand, or even more.

A large amount of materials for the ion engine device, Ye Fan is in the preparation process.

And in this hurried period of a few days.

The first dungeon has been excavated to a position of 1,500 meters and is being expanded 1,500 meters underground.

In the process of excavation.

They also dug into the underground river, but it was quickly sealed.

Once the underground river is poured into the dungeon, the consequences are unimaginable.

Once blocked, use it later!

While the dungeon expanded, hundreds of floors were built, and each floor could accommodate five or six thousand people.

Hundreds of floors, at least able to accommodate millions of people.

Each layer is quite sturdy.

It's very strong.

On each floor, an artificial solar device is installed.

Human beings need to absorb the sun, and without the sun, the body will be diseased.

And at the bottom of the grassroots, it is not used to live in the population, but to grow some food.

Potato.

Sweet potato.

These easy-to-grow organic matter, in the works!

It's just an experiment.

See if you can plant successfully.

Each floor has huge air filters that lead to the ground.

Air conversion device, this kind of technology, major groups have long been studied.

These air converters are capable of filtering a lot of air with impurities, air with radiation.

However, it consumes a lot of filter elements, and there are filters.

The major groups are already in the process of continuous production.

None of this is a big deal.

The underground city line is also a huge project, where is the source of the electricity consumed in the underground city?

It's that ion engine.

Eighteen suspended elevators.

Why use a suspended elevator?

Even if the earth stops rotating, the gravitational pull still exists, can people still float after the rotation stops?

Isn't that?

As long as there is gravity, the levitation engine can be used as usual, and you must know that the core of the earth itself is a huge magnetic force.

Therefore, gravity will not disappear, and in space, there will be no gravity, otherwise, countless spaceships can be built just by relying on levitation engines.

The suspension engine is mainly used, and that is because the lifting speed of the suspension engine is fast enough and stable enough.

He won't be the same as the elevator.

Once there is no power supply, it can't be used, once something goes wrong, it will be stuck inside, once the elevator is stuck, and if you want to rescue, it will take a lot of work.

Dungeon No. 1 is complete.

This has excited countless scientists, as well as regional officials.

The excavation is done, and the next step is construction.

None of that is a problem.

The problem is that in such a short period of time, a dungeon has been excavated, so how can other dungeons be able to do so fast?

The officials in all major regions have more confidence in Ye Fan's plan!

After the dungeon is completed.

Ye Fan immediately gathered a large number of people and began to build the infrastructure of the ion engine.

The construction of an ion engine is quite complex and very large.

You can see the huge ion engine in the city next door.

You can imagine how huge the ion engine is.

The ion engine is the size of a giant mountain.

It's majestic.

This shows how complex the work inside is.

Where the No. 1 ion engine was built, it was a small city, and now the entire population has been forcibly relocated.

And it's very fast.

Not at all to give them any chance to react, everyone has already moved forward.

They don't understand what really happened.

Why?

But I heard that something was going to be built here.

They don't understand.

But countless workers and countless excavators, all kinds of construction vehicles have long arrived in the city.

A huge foundation is under construction.

The foundation is mixed with H agent, which is extremely strong and very hard.

There is even a lot of graphene powder mixed in it.

Make solids stronger.

And the news of the relocation soon exploded on the Internet.

"Fog grass, have everyone migrated, what kind of operation is this, it's too showy."

"I don't know what happened, so many people were relocated!"

"I heard that it seems that something is going to be built there, anyway, it is extremely huge, there is no way, but it can only be moved, but they have also become the second generation of demolition, and they have become rich one by one, and I also want to become the second generation of demolition!"

Some people are envious, some people are confused, some people are frightened, and some people don't care.

But soon the news sank.

What is to be built?

Won't you know when you build it?

On Ye Fan's side, he encountered a troublesome thing, which was naturally the reason for the ion engine!

Inside the huge ion engine, there is a huge central shaft that is 30 meters high and 10 meters wide!

Without this central shaft, the huge ion engine would not have been able to rotate at all, and would not have been able to excite energy power.

This central axis is very important!

And this central axis, with Ye Fan's current factory strength, cannot be mass-produced at all.

There is no such means in the world that can forge a central shaft that is 30 meters high and 10 meters wide, right?

This is the problem that Ye Fan is currently encountering!

He wanted to solve this problem.
