Chapter 753： : Crisis appears! Be sure!

Marlow Jack's face was somber and struggling.

Ye Fan ruined his life.

He also wanted to ruin Ye Fan's plan.

It's just that if Ye Fan's plan is ruined, it will become a sinner for all mankind, and it will also lead to the inability of this plan and the complete destruction of mankind. Will he really be a sinner forever?

Ah!

My own life is gone, the ancient sinner, it is also famous!

Malo Jack, who had a headache, couldn't even think about it.

He is waiting.

If the official does not find him, then he really has to do it.

....

Another half month 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 two diamond drill bits can be produced every day to the present day, 50 diamond drill bits can be produced every day. The change in speed is already flying.

And those scientists have just learned some knowledge now.

It is still very difficult to learn this technology, but if they add these laser machine tools and only need to produce, they are already competent. After all, they have learned knowledge.

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

Ye Fan's current direction is the ion engine.

The core of the ion engine, the flint ignition device, now Ye Fan has produced thousands of them, and it is still far away. At least one hundred thousand or more are needed.

Ye Fan is in the process of preparing a large amount of materials for the ion engine device.

And this hurried few days.

The first underground city has been excavated to a position of 1,500 meters, and it is expanding 1,500 meters underground.

In the process of digging.

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

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

After blocking, use it later!

As the underground city expanded, hundreds of floors were built, and each floor could accommodate 50,000 to 6,000 people.

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

Each floor is quite strong.

Very firm.

On each floor, there are artificial solar installations.

Humans need to absorb the sun. Without the sun, the body will be affected.

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

potato.

sweet potato.

These easily grown organic matter is in the process!

This is just an experiment.

See if you can plant successfully.

Each floor has a huge air filter that leads to the ground.

Air switching devices, this technology, have long been studied by major groups.

These air converters can filter a lot of air with impurities and radiated air.

However, it consumes filter elements and filters.

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

These are not major problems.

The underground city line is also a huge project. Where does the energy consumed by the underground city come from?

It is that ion engine.

Eighteen floating elevators.

Why use floating elevators?

Even if the earth stops rotating, the gravity still exists. Is it possible for people to float after stopping rotation?

Isn't that nonsense?

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

Therefore, gravity will not disappear, and in space, there will be no gravity, otherwise, relying on the suspension engine alone can create countless spaceships.

The main use of suspension engines is that the suspension engines are fast enough and stable enough.

He will not be the same as the elevator.

Once there is no power supply, it cannot be used. Once something goes wrong, it will be stuck inside. Once the elevator is stuck and you want to rescue, it will take a lot of time.

Dungeon One is completed.

This has excited countless scientists and officials from major regions.

After the excavation work is completed, the next step is construction.

Those are not things.

The problem is that in such a short period of time, an underground city has already been dug, so can other underground cities have such speed?

Officials in major regions have more confidence in Ye Fan's plan!

After the completion of the dungeon.

Ye Fan immediately summoned a lot of manpower and began to build the infrastructure of the ion engine.

The construction of ion engines is quite complicated, but also very large.

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

I can imagine how huge the ion engine is.

The ion engine is as big as a giant mountain.

Very majestic.

This will tell you how complicated the work inside is.

Where the No. 1 ion engine was built, it was a small city, and now all the population has been forced to relocate.

And it's very fast.

They did not give them any chance to respond, and everyone has moved forward.

They don't understand what happened.

Why do you do this.

But I heard that something seems to be built here.

They don't understand.

But countless workers and countless excavators, and various construction vehicles have long arrived in this city.

A huge foundation is under construction.

The foundation is made by mixing the H agent, which is extremely strong, and the hardness is very high.

There is even a lot of graphene powder inside.

Make the solid stronger.

The news of moving the city soon became popular on the Internet.

"Mistgrass, has everyone migrated? What are these operations, too?"

"Unconsciously, what is happening, so many people are migrating!"

"I heard that there seems to be something to be built there, anyway, it ’s extremely huge, there is no way to do it, but they can only migrate. ! "

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

But soon the news sank.

What to build?

Then build it ~ www.novelhall.com ~ Don't you know?

Ye Fan encountered a troublesome thing, which is naturally the reason of the ion engine!

There is a huge central shaft with a height of 30 meters and a width of 10 meters in the huge ion engine!

Without this central axis, the huge ion motor would not be able to rotate at all, and it would not be able to excite energy power.

This central axis is very important!

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

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

This is the problem Ye Fan is currently facing!

He wanted to solve this problem.
