What appeared in front of Li Fan's eyes was not a super base full of advanced equipment as he imagined. Pen "Fun" Pavilion www.biquge.info

It's more like an antique with mottled traces of time everywhere.

Metalwork is covered with oxidized rust, and in its long history, few metalworks have escaped the end result of oxidative rust, except for some antiques that have been preserved by chance.

Li Fan touched the monitor, which was dilapidated but still maintained its approximate shape.

Nuwa said in an apologetic tone

"Chief, I'm sorry, I didn't manage to protect this base, and despite my best efforts to protect them, the base still lost eighty percent of its functionality. ”

Li Fan asked in a deep voice

"No, you've done a great job, and to be honest, I'm amazed that this place is preserved like this.

According to common sense, the more delicate things are, the faster they will be damaged, how did this base survive?

In addition, most caves and underground facilities will collapse due to excessive gravity.

Here........."

Nuwa guided Li Fan to the base blueprint.

The design is carved into the stone wall, and perhaps because of this, the pattern and handwriting on it are still clear.

And then he said

"Chief, I don't know if you know about architecture, but the houses that humans used to live in were fifty or seventy years, not that the life of the house was only so little.

The cement generates a large amount of calcium hydroxide in the hydration process, so that the concrete void is filled with saturated calcium hydroxide solution, and its alkaline medium has a good protective effect on the steel bar, so that the surface of the steel bar generates insoluble Fe2O3 and Fe3O4, which is called the purification film.

If the protective part of the reinforced concrete is thick enough. The concrete carbonization reaction takes a long time to penetrate the protective layer, so the building life can even reach a thousand years if the environment is suitable.

The design standard of the Pangu Civilization Library is much higher than the 20-30 mm concrete of ordinary buildings. So it was able to be saved until now. “

Li Fan nodded to indicate that he understood, and then raised a second question

"Nuwa, did there ever be a human life in the Civilization Library?"

Nuwa paused

"Yes, there were more than 600 people living in the Pangu base, among whom the elderly died of cardiovascular and cerebrovascular diseases caused by the sudden arrival of hypergravity.

Subsequently, due to the lack of living resources, the inability to light the flame, epidemics, civil strife, and the number of women was too scarce.

The last survivor of the base died 792 years ago. ”

Li Fan sighed softly, then put these things behind him, and continued to check the parts of the base that were still intact.

And Nuwa has been introducing it all the time

"Chief, the storehouse of the Pangu base adopts a multi-level preservation method.

The whole warehouse is kept at minus 18 degrees Celsius, the outermost layer is filled with inert gas, and the inner layer is kept in vacuum. When the outermost layer of protection fails, the second layer acts as the original inert gas protection layer. ”

Li Fan stopped and frowned

"Even if it is so isolated from oxygen, because of the stress of the metal itself, and the change in entropy, a thousand years....... I guess it's all gone. And I really want to know, Nuwa, after more than a thousand years, can the computer still work?"

Nuwa was silent

"Chief, you're right, the things in the warehouse are basically damaged... As for myself .... One, I'm a biocomputer with self-healing capabilities, and second, I've been using what's in the base for self-maintenance.

But so far, all I can use is the two toy cars that were put together, and some auxiliary machinery.

If you don't come, it is estimated that in a few more years, the entire base will be completely scrapped. ”

Li Fan smiled bitterly twice

"So... I'm basically dealing with scrap stuff?"

"No!" Nuwa said softly

"My father, you have left you the most precious treasure!"

................

Li Fan stood at the door of a warehouse, his body trembling, and at this moment he just wanted to shout loudly.

No matter what he said, it was not enough to show the excitement in his heart, and he moved almost step by step to the warehouse, gently stroking these things.

The warehouse is indeed the most valuable wealth, and even Li Fan feels that these are the most valuable things in the world now.

Because Nuwa's father left himself an industrial machine tool - a machine tool.

How could Li Fan, a master of mechanical engineering, not know these things.

I didn't sweep a single machine, and my mouth began to mumble to myself

"Boring machines, lathes, milling machines, planers, grinding machines"

Li Fan burst into tears, what do these machine tools represent?

It represents the sheep village from the original primitive farming era, to the industrial level after World War II! This means that as long as there are raw materials, what steam engines, cannons, guns are not a dream, and even other machine tools that are several generations behind can be used with these machine tools!

This means that Yangcun has embarked on the road of great strides forward since then, and it means that Yangcun is the same as China back then!

Li Fan's body shook, and suddenly thought of a serious problem, and turned his head sharply and said

"Nuwa! After more than 1,000 years, although these machine tools are relatively backward manual machine tools, but because of metal stress and entropy changes, is the accuracy still guaranteed?"

Nuwa said softly

"So, these things are the precious treasures left by my father to future generations...... Although there are only five machines here, their materials are not on earth, and the properties of these materials ensure that they will be able to preserve a high level of precision even after another thousand years.

Originally, these metals were only stored in the laboratory for experimentation.

After the cataclysm, it was urgently transferred and made into these machine tools. Because the father had already thought of the most terrible outcome. ”

Li Fan's eyebrows twitched twice, and he asked in surprise

"Special metals codenamed A2D577S?"

Nuwa let out a "huh" and said with some surprise

"It turns out that the chief also knows about this metal! But according to the identity information of the chief before the cataclysm, he should not have access to the top secrets of these countries! Could it be the membrane world?"

Li Fan nodded, his heart full of shock

The reason why he knew about this metal was because of the discovery of an inspection report for this metal in a research institute codenamed 486.

Reports show that the metal surpasses any metal known on Earth, including alloys, and is extremely malleable to be called a perfect metal.

Unfortunately, it came from space, the outer layer of Adam's metal.

At that time, this meteorite suddenly appeared in the Gulf of Aden, as if it had penetrated space.

After a secret dispute, the United States snatched the core Adam metal, while China snatched 90 percent of the outer metal, and the rest could only share the remaining 10 percent.

The most important thing is

The dog's body and other parts are all made of this metal by Li Fan!
