Thirty meters high.

A central axis with a width of fifteen meters.

Ye Fan looked at the design drawing, his brows furrowed.

Can't you just build it piece by piece and put it together?

No way.

The central shaft must be integrated, that is, it must be forged to perfection, if it is pieced together, once the ion engine is started, it will explode!

It's like a musket.

The barrel is not perfect, if there are some flaws.

There will be the consequences of exploding.

If the central shaft is blown up, can you imagine the consequences?

In an instant, an ion engine was directly blown up.

What if 60,000 ion engines were all cobbled together with a central shaft?

The consequences made Ye Fan dare not imagine.

Today's forging methods are simply not enough to forge this central shaft.

Unless.

Able to build a huge forge.

That's how it is possible.

How huge does it take to forge a central shaft?

A central axis of 30 meters high and 15 meters wide.

The forging furnace should be at least 100 meters high and 50 meters wide to perfectly create the central shaft, right?

100 meters high.

How much furnace fire does it take to fire?

How much forging skills do you have to build it?

At the moment, in the makeshift research base of scientists.

Ye Fan, Professor Ma, and many other scientists gathered around, and they were discussing how to build this central axis!

"Mr. Ye, can't you do anything?"

Several scientists were very unwilling.

The good news of the dungeon excavation is simply a shot in the arm in their hearts, and now they are more confident to leave the solar system.

And what I didn't expect was.

Now we have encountered such a huge problem.

Central axis.

If this problem is not solved, there will be no way to build and produce ion engines.

"No way, unless you can think of a better way to come out!"

Ye Fan met and communicated with them, in fact, he wanted to use this opportunity of exchange and cooperation to see if the billions technology system could give an answer.

Whether it is possible to give a forging central shaft technology out.

These scientists are experts in this field.

And they were all stumped at the moment.

So that's possible.

Forging a central shaft is not possible unless it is a huge furnace.

Besides.

Doesn't seem like there's any other way?

Ye Fan closed his eyes tightly and began to flip through the list of billions of technologies.

[Flare Forge Pillar: 1,500,000 Fame!] 】

Well?

Ye Fan's eyes lit up suddenly.

Isn't the Flare Furnace Pillar the thing that makes the central axis?

See details.

It turns out that the flare furnace column uses a high temperature of hundreds of millions of degrees Celsius to directly melt all materials into molten iron, such as molten steel.

And what about the furnace columns.

When molten iron is poured, the furnace column has the same function as the furnace, and on both sides of the column, there are countless automatic mechanized hammer forging.

After the molten iron inside solidifies into a cylinder.

Those hammer forges begin to forge.

Constant forging.

To create a central axis, it takes at least a week to create a perfect central axis.

And it will take a week to build and produce such a flare furnace column, which is also the fastest speed that Ye Fan expected!

"I'm sorry guys, I have something to do, so I'll leave first!"

Ye Fan said directly and left early.

Leaving a place, the scientists frowned.

They finally got a task.

I didn't expect the whole task to be difficult to climb.

What can I do?

Mr. Ye can't do anything, so what can they do?

When Ye Fan returned to his office, he turned on the protection mechanism.

The exchange of 1.5 million prestige points, Ye Fan has not exchanged it, and the last time he exchanged it, there seemed to be no problem at all.

This redemption.

And so it is.

【Redeem!】 】

[Ding, after deducting 1.5 million energy points, it has been exchanged for a Flare Furnace Pillar!] 】

Rumble!

Countless tons of data hit the brain.

Even Ye Fan felt that he was in an extremely hot place, and that place seemed to be able to heat people to death.

He's watching up close.

Even in memory.

This Flare Forge Pillar is just a matter of self-made!

After that heat wave was gone.

Ye Fan also woke up.

I'm soaking wet.

The scene just now is as if you are there.

If it's a higher-level technology unit, what will it be like when you redeem it?

After getting this technology.

Ye Fan slowed down and began to proceed.

This flare furnace pillar is only a few tens of meters high.

The width is more than 20 meters.

It's enough to use.

Another few days on end.

There are many areas where diamond drill bits have been obtained, and dungeons have been dug up.

More and more areas, the number of dungeons they excavated and built is increasing.

The program is already on track!

"Brother Ye, Brother Ye, we have come up with a very perfect plan!"

"Let's forge the central shaft!"

It's no secret that the central axis has become everyone's biggest problem, and it has long been spread in the ears of countless scientists.

In particular, the major regions also knew about it, and they were even more anxious.

The central axis became a problem, the ion engine could not be built, and the dungeon they dug could only become a safe house to hide.

And the solar system still can't escape!

"Oh? What's the solution? ”

Ye Fan watched Professor Ma come with dozens of people, and immediately asked.

Tens of thousands of scientists are thinking about how to forge the central shaft and how to produce the central shaft!

"Brother Ye, we have built a furnace with a height of 100 meters and a width of 50 meters, which is exactly the same as the forging furnace, so that the central shaft can be produced!"

When Ye Fan heard this, he immediately frowned.

I thought they had come up with some good plan.

Isn't it exactly what you thought before?

But they seem to have built it.

"Take me to see it!"

Everyone came to the park of the Future Technology Crystallization Company, and the huge furnace stood in front of Ye Fan.

The corners of Ye Fan's mouth twitched slightly.

They are really fast, and I don't know how much human resources they use.

In such a short period of time, this furnace can be built!

"Have you tried it?"

Ye Fan asked.

When Professor Ma heard this, his face immediately turned slightly red and said: "Because the furnace was built in too much time, many details were not added, resulting in the problem of furnace leakage, and it is currently unusable, but we would like to ask Brother Ye to give some advice, and see if we can build a better one!" ”

The people around also looked at Ye Fan expectantly.

And Ye Fan smiled and said, "This furnace doesn't look good!" ”

"What do you think of me?"

Ha?

Ye Fan researched a set of furnaces by himself?

Everyone was stunned!

When's it?
