40,000 Years of Cultivation

The air circulation magic weapon and the refining of filter chips are both very mature and reliable technologies. Even as early as tens of thousands of years ago in the Great Dark Age, people were riding starships with air circulation magic weapons and galloping in the vacuum of the universe. .

No matter how the wars of the past ten thousand years destroyed the technology, this most basic refining technology has never been lost. Even the Star Federation at the seaside of the stars has developed to the highest level, the super large air circulation system in the Star Wars Castle. , Enough for tens of millions or even hundreds of millions of people to breathe the freshest air at the same time.

The technical level of the true human empire is at least dozens to a hundred years more advanced than that of the Star Federation. Naturally, there are many technologies in the field of air circulation, let alone.

In Li Linghai's Deep Sea Dragon Palace, Li Yao obtained a large amount of information on the imperial starships, and he has extremely in-depth research on the air circulation systems of these starships.

Even if it is a heavy starship refined hundreds of years ago and has a length of more than ten kilometers, its air purification, filtration and circulation system still does not have any technical difficulties. With a little bit of highly concentrated "conversion agent", it is an energy source. Constantly turning the exhaust gas into fresh air, and using molecular series "filters" to filter out all kinds of poisonous substances, and even when raging flames are ignited inside the starship, strong black smoke and poisonous fog are released. Will not affect the combat effectiveness of the entire starship.

The air circulation magic weapon used in the deep underground is slightly different from the same type magic weapon carried by the starship. It does not pay much attention to the airtightness, but particularly requires high temperature resistance and vibration resistance.

This is not a big problem. Li Yao knows that there are several special ceramic materials. As long as a thin layer is sprayed on the surface of the component, the heat resistance and seismic performance can be greatly improved. The technology is not complicated, and the cost is definitely not considered. Go high.

however……

In the core unit of the air circulation magic weapon used in the 10084 area, all the purification chips and exchange units are rusty and weird. The engraved symbols on the surface and inside are crooked like a child's botched painting, and there is no heat insulation treatment at all.

Because it runs day and night without a good ventilation and heat dissipation system, the temperature inside the magic weapon unit is already extremely high, and even a light poke with a finger can poke a shallow hole.

Such a component is not "crude manufacture" at all, but it is far behind the times. Even with the magic component assembly line of 500 or even 800 years ago, such a clumsy product cannot be refined, the ghost knows These things are refined in which small workshop.

It’s no wonder that the air in the town can be fresh with such a copycat. No wonder Li Yao smells a dull and dirty smell from beginning to end!

Li Yao's heart was irritated, and he even felt nauseous and nauseous-letting a master refiner like him see this kind of shit-like magical artifacts was tainting his eyes and heart. He endured his anger and straightened up. Waist, shouting at the underground people outside: "Who purchased these magical components and installed them? Who bought them from? You are all fooled!"

Li Yao's voice reverberated in the huge cave. It was smashed by stalactites and stalagmites, but there was no spray. The underground people who were originally hiding in the stalagmites, mushrooms and fungus fog and looked at them with their heads looked like all the underground people. Like a frightened four-legged snake, he quickly retracted his head.

"It's useless, Brother Yao, don't shout, except for a few specialized talents trained by Sister Long, others won't talk to us."

Li Jialing explained, "The underground people regard us as immortal cultivators, at least people who come down from a very high ground.

"For thousands of years, the immortal cultivators on the ground have never brought any benefits to the underground people. On the contrary, they have only brought enslavement, destruction and disaster. Any place where immortal cultivators appear often means that they have been found there. The precious mineral veins and ruins mean that nearby villages will suffer!

"Over time, the fear of the people on the ground is deeply imprinted in the flesh and bones of the people on the ground, and the only way for the people on the ground to resist is silence.

"There have been countless experiences and lessons-the cultivator heard that new mineral veins and relics were discovered in the ground, so he pretended to be amiable and went to the ground, even under the name of His Majesty the Emperor's care for the ant people and the free assistance of the major sects. Under the banner of, sent a large amount of urgently needed materials from the underground, but in fact, it was for the purpose of exploring the information of mineral veins and relics from the underground population.

"When the information is available and the coordinates and reserves are ascertained, the immortal cultivator will immediately turn his face and deny the people and completely destroy the village. All the villagers are either killed on the spot or squeezed to death.

"This kind of thing has happened hundreds of times, and there will always be wind leaks. Over time, all underground people know that talking to people on the ground will bring disasters. You must keep your mouth silent and stay away."

Li Yao frowned and said, "Aren't we the distinguished guests of the'worry girl'?"

"Because we are Sister Long's distinguished guests, they dare to watch us boldly, so that the maid can say a few words to us."

Li Jialing said, "Otherwise, once people on the ground like us appear here, maybe everyone will hide in the deepest part of the cave, huddling with the rock worms and shaking!"

Li Yao sighed, his eyes pierced through the dense fog again, and even pierced the rock-cold and hard shell of the people underground, as if he could perceive the real fear, tension, confusion, even a little bit under their indifferent appearance. ……look forward to?

Li Jialing continued: "In fact, you don't need to ask them for such a simple question. If you think about it, you will know-if the magic artifacts sold to them are not so awkward, they will be broken in two days, but the high-quality products used on the ground. Even qualified products can be used stably for a long time. Isn’t there any problem with the oxygen supply deep underground?

"There is no problem with oxygen. What Rockworms have is that they are completely self-sufficient here. How can the three-digit and four-digit towns above control the five-digit towns in District 10084? How can they use a small can of compressed air? How about replacing dozens or hundreds of rock worms?"

Li Yao was startled slightly, his eyes gradually cooling down.

Li Jialing smiled bitterly: "Relying on the omnipotent brother Yao, after half a year of carefree, heartless life, I seem to have gone back to the past to fight with Li Lingfeng, Wu Yinglan, wit and courage. It’s a day when the brain cells will be stimulated to the limit in seconds. It’s really... uncomfortable to see everything so clearly!"

Li Yao stopped talking, knelt on one knee in front of the air circulation magic weapon, squinted his eyes, and listed the materials in his universe ring, as well as repair and post-maintenance plans in the depths of his brain.

Repairing the air circulation magic weapon is really a piece of cake for a master like him who can repair even giant soldiers.

But Li Yao spent a full five minutes thinking, polishing the entire plan with the most cautious and meticulous attitude, and then he tried his best to refine all the magic components in an entire hour, those The really unusable scrap copper and rotten iron were simply thrown away and replaced with the treasures he cheated from Li Linghai, and he did not hesitate to consume the still extremely weak primordial spirit, using molecular-level three-dimensional micro-sculpting to reorganize the entire cycle and Purification system.

As for the conversion agent that converts carbon dioxide into oxygen, there is no finished product in his universe ring. Fortunately, the preparation is not complicated. Li Yao does not frown. He uses several priceless coolants and combustion aids on site. Combining a bucket, with all the residents of District 10084 plus the consumption of rock worms, it should not be a problem to support it for two to three years.

"Finish!"

Li Yao looked at the shining magic weapon components as bright as new, smiled slightly, closed the cover of the core unit lightly, and fine-tuned the running talisman array next to him.

Suddenly, a stream of fresh and cool air spewed out from the "towering trees" to the branches and roots of the whole town, just like a pattering rain on a hot summer afternoon.

Numerous underground people have been cautiously spying on Li Yao's movements from a distance, neither daring to stop him, nor knowing what he is doing. It was only at this moment that they vaguely understood the probabilities, and they couldn't believe what their eyes and skin felt. , Is dumbfounded, dumbfounded.

They have been for a long, long time, perhaps thousands of years. Starting from the grandparents of their grandparents, they didn't know what it was like to be "ecstatic". The darkness and embarrassment of reality even forced them to accept Long Yangjun's "goodwill" and gave up. Full of pain and despair.

But now, the long-stained brain suddenly made waves, stiff, distorted, and weird expressions appeared on their faces, sweet, bitter, and salty, flowers blooming hesitantly on the faces of men, women and old people, they all As if drunk, he staggered and danced.

"Dear folks, I just repaired your air circulation system, gradually restored the oxygen content in the air to normal levels, and purified the poisonous substances in the air. You have been accustomed to living in low levels for a long time. In the area of ​​oxygen concentration, a sudden increase in concentration will cause the phenomenon of "drunken oxygen", but it will not affect you at all. It will only make you smarter and stronger. Don't be nervous!"

Li Yao straightened up again, regardless of whether the underground people could understand him or not. After he understood, he didn’t believe him. He just said loudly, “I found that the overall cooling system of this town also has many hidden dangers. , After returning from deeper underground, I will help you repair it. After that, I will compile a complete set of repair and maintenance procedures into an "Operation Manual" and give it to you. You can repair and maintain it yourself in the future-believe Me, it's not complicated.

"However, to be on the safe side, you'd better choose the two representatives with the most flexible brains and the strongest hands-on ability. Then I will teach them first by hand, and then teach them to everyone. In this way, you will never again. You don’t have to trade rock worms that you’ve cultivated so hard for insignificant compressed air, and you don’t need to be exploited by a higher level!"
