As the underground space continues to be excavated, the layers of soil overhead are constantly being excavated.

Large areas of metal ore veins appear in the underground space in a clear layer, and some metal ores are unknown to An Wen.

Fearing the presence of radioactive minerals, An Wen left the underground space with the disc.

He deliberately returned to the base to check the list of chemical technologies.

"Is there so much minerals in the underground space?"

Looking at the list, except for radioactive metals and some rare earths, most of the metal ores have been lit.

Even the chemical list, energy list, and material list have been turned into a state that can be lit up due to the discovery of underground space ores.

A wave of fat, a wave of fat!

An Wen saw the icons on the screen, and his heart was happy.

"The steel smelting icon lights up."

"The special alloy icon lights up."

"The ultra-high-pressure high-temperature boiler icon lights up."

"Chemistry, Energy ......"

The rows of icons and the branch icons below are all lit up by Anwen.

"I'm a little dizzy."

An Wen shook his head and sat aside.

There is too much knowledge that has been poured into my mind in a short period of time, and my brain is a little dizzy.

After half a ring, An Wen finished sorting out the knowledge instilled in his mind, and the whole person swelled again.

"Ultra-high tensile strength alloys, super wear-resistant alloys, super fatigue-resistant memory alloys, super high-temperature resistant alloys, ......"

Other knowledge, An Wen doesn't care very much.

Especially in chemistry, because that knowledge is equivalent to the earth, it still belongs to backward chemical technology.

But in terms of metal smelting, all kinds of super-strong alloys really excited him.

As a student majoring in aircraft design and engineering, An Wen is simply very clear about the heart disease problem of domestic aircraft.

Taihang and Kunlun are both good.

But in terms of materials, it is really not good.

In other disciplines, whether it is mathematics, physics, even biology, we can quickly catch up with good scientists, with ingenuity, and even overtake in some areas.

But in terms of materials science, there is really nothing that can be done.

Mathematics has formulas and theorems.

Physics has theories as well as formulas.

But what does materials science have?

Oh, you said there was computational materials.

So you tell me, what calculation method do you use to be able to calculate super steel with a tensile strength of more than 3000 megapascals?

I can't calculate it, there is no formula to set it, to calculate.

If you want to make a breakthrough in materials, one is to burn money.

Take the money and throw it directly into the steelmaking furnace, all kinds of materials are taken and burned, and after a lot of failures, you may get a powerful material with a bit of luck.

The other is to open the hanging.

Find a researcher and let him think about it by himself, and do whatever he wants, and then luck comes, and the materials come out.

That's right, materials science, more than any other discipline, requires luck.

Sometimes my ability to think is more useful than any experience.

Now An Wen doesn't even think about it, just open it.

"I can build a real aircraft engine right now."

The inflated An Wen has already hit the plane with his thoughts.

Not to mention, he can actually make it.

The technical difficulty of the turbojet engine lies not in the theory, but in the difficulty of materials and manufacturing.

Materials, materials that Anwen has now, are cross-generational levels.

As for the difficulty of manufacturing, when he manufactures ultra-high-precision machine tools, the machining accuracy can reach 0.002.

These two problems are solved, even if the engine designed by Anwen is defective, as long as the materials can keep up, increase the temperature of the combustion chamber, increase the speed, and the thrust will not come up.

In the same way, even if the aerodynamic layout of the aircraft designed by Anwen is garbage, as long as the materials can keep up and the thrust is strong enough, it can still go to the sky.

Flying bricks vigorously, terrifying!

After fantasizing for a while, An Wen honestly went to build a factory again.

If you want to do everything in his fantasy, you have to work honestly now, if the hydraulic press can't be built, how to do the large forgings of the aircraft.

In the blink of an eye, three days passed.

After three days of excavation, the soil layer on top of the underground space has been completely excavated.

At this time, the mine has turned into a huge deep pit.

The sun shines directly into the bottom of the pit, and the colorful veins of various ores shimmer with strange light.

On the rock wall at the edge of the pit, five long robotic arms hang the wheel bucket.

"Excavation."

Anwen stood on the console and pushed five joysticks.

Click......

The bucket began to spin, and soon a large pile of ore burst out from the veins below, which was poured down the conveyor belt into the warehouse.

"Now that we have all kinds of ores, we can produce large machinery and equipment."

In the past two days, he has already built the factory.

It's just that there is no production equipment yet, and the equipment plant is worthy of its name.

Following the mine walls, Anwen returned to the base of the valley.

The night before yesterday, An Wen blocked the entrance to the mine with a small fortress.

As expected, the source of the monster is indeed an underground mine.

When he blocked the entrance to the mine, the walls on the other side of the valley were never attacked by monsters again.

"Do you spend 500,000 survival points to produce precision lathes?"

"Sure."

"Whether to spend 5 million survival points to accelerate."

"Sure."

"...... or not"

Anwen is in the complex building, constantly spending survival points, and directly manufacturing a set of precision machine tools.

In just a few minutes, he spent hundreds of millions of survival points.

When these precision machine tools are manufactured, Anwen puts them into the factory.

Returning to the complex again, An Wen continued to kryptonite.

"Whether to spend 3 million survival points to produce high-precision machine tools."

"Sure."

"...... or not"

High-precision machine tools are much more expensive than precision machine tools, and the variety has not decreased.

But even so, An Wen gritted his teeth and spent billions of survival points to point out all these high-precision machine tools in a short period of time.

After putting these high-precision machine tools into the factory, Anwen returned to the complex again.

"Whether to spend 20 million survival points to make 10,000 tons of hydraulic presses."

"Sure."

"Whether to spend 200 million survival points to accelerate."

"Nope."

Anwen has a toothache, just a 10,000-ton hydraulic press, 200 million.

The 100,000-ton hydraulic press behind it won't cost 2 billion?

Not to mention, he also needs to manufacture large machine tools and super large machine tools, 100-ton gantry cranes, super large steelmaking furnaces and other equipment.

If all the kryptonite is accelerated, the survival points he has saved will not be enough.

"Forget it, you can't be so impatient, it's nothing two days late."

An Wen closed the list, smiling and comforting herself.

What could he do?

I can only face it with a smile.

"In five days, five days at most, I will be able to complete the industrial system...... Well, it seems that it is still a lot short of the entire industrial system. ”

An Wengang wanted to brag, but he thought of those icons of the whole industrial system.

Sorry to bother me.

Not to mention the full industrial system, he is not even full of heavy industry now.

But in general, when this batch of equipment is manufactured, he will be able to start building a steam-mechanical megacity.
