Forty Millenniums of Cultivation

Air Circulation Treasure and Filter Chip Refining are very mature and reliable technologies, and even tens of thousands of years ago, in the Great Dark Ages, people traveled across the cosmic vacuum aboard starships with Air Circulation Treasure.

Regardless of how the fires of the past 10,000 years have destroyed technology, this most basic refining technology has not been lost, and even the star-boarded Federation of Stars has grown to the point of peak creation. The supermassive air circulation system in the Star Wars Fortress is sufficient to allow tens of millions or even hundreds of millions of people to breathe the freshest air simultaneously.

The technological level of the Real Human Empire, at least a few decades to a hundred years ahead of the Federation of Stars and Glows, naturally goes even further than the many technologies in the field of the air cycle.

In the deep sea dragon palace in Li Linghai, Li Yao received a large amount of information from Imperial starships, and the air circulation systems of these ships were studied in great depth.

Even a heavy-duty starship that was refined hundreds of years ago and is more than a dozen kilometres long, with its air purification, filtration and circulation system, still does not have any technical difficulty. With a little highly concentrated “converter", it can continuously turn the exhaust gas into fresh air, and use molecular "filtration sieves” to sieve away all of its poisons. Even when the flames of the bear burn inside the starship, releasing intense black smoke and poison fog, it will not affect the operational effectiveness of the entire starship.

The air circulation treasure used deep beneath the ground is slightly different from the treasure of the same type on board the starship. It is less about sealing, but requires special resistance to high temperatures and vibrations.

Nor is this a big problem, Li Yao knows several special ceramic materials. If you spray a thin layer on the surface of the member, you can greatly improve the heat and seismic resistance, the technology is not complicated and the cost is definitely not high.

However……

All the purification chips and exchange units in the core unit of the air circulation method used in Zone 10084 are rusty and oddly shaped. Both the surface and the interior engraved symbol array are distorted and twisted like a child's poor application without any insulation treatment at all.

The temperature inside the Pharmacopoeia unit is already extremely high because it keeps running day and night without a good ventilation and heat dissipation system. Even a finger can poke out a shallow hole.

Such components are not at all described by the word "coarse and indiscriminate", but are far behind the times, even with 500 years or 800 years old Fabao component pipeline, can not produce such a bad product, ghosts know which small workshop is producing these things.

With this kind of mountain colour, the air in the town can be fresh. No wonder Li Yao smells dull and dirty from beginning to end!

Li Yao looked at his head and even felt nauseous and disgusted —— let a master refiner like him see this shitty Pharaoh component, which was really tarnishing his eyes and soul. He endured anger, straightened his back and shouted at the underground people outside: “Who bought all these Pharaoh components back and who installed them? Who did you buy it from? You've all fallen for it! ”

Li Yao's voice echoed in a huge cave, smashed by clock milk and stone shoots, but didn't lift a little wave. Those who were hiding in stone shoots, mushrooms and fungus fog, probed the underground people whose brains looked at them, all like a frightened four-legged snake, quickly shrunk their heads back.

“It's useless, Brother Yao, stop shouting, no one will talk to us except the very few professionals trained by Sister Long. ”

Li Jialing explained, "The underground people treat us all as fairy fixers, at least those who come down from very high ground.

“For thousands of years, fairy cultivators down on the ground have never brought any benefit to the underground. On the contrary, only slavery, destruction and calamity have been brought about. Where fairy cultivators have appeared, this often means that precious minerals and relics have been found there, and that the nearby villages will suffer!

“Over time, fear of the grounders was deeply engraved in the flesh and bone marrow of the grounders, whose only way to resist was silence.

“There are countless lessons learned - the immortals, when they hear that new minerals and relics have been discovered underground, come to the underground in a friendly manner, even sending large quantities of much-needed materials under the banner of His Majesty's care for the ants and the pro bono assistance of the bulk factions, in fact in order to find information about the minerals and relics from the underground population.

“As soon as the information was available, the coordinates and reserves were clearly detected, the immortal turned his face and completely destroyed the village. All the villagers were either silenced on the spot or pressed to death alive.

“This has happened hundreds of times without knowing it, always leaking a sound, and all underground people who have known for a long time that talking to people on the ground can cause disaster, must remain silent and respectful. ”

Li Yiu frowned: “Aren't we the VIP guests of" Forget the Heavenly Girl "? ”

“It is because we are the guests of the Dragon Sister that they dare to look around us so that the maid can speak to us a little. ”

Li Jialing said, “Otherwise, if a grounder like us shows up here, maybe everyone will hide in the deepest part of the cave and shake with the rock worm! ”

Li Yao sighed, his eyes pierced the fog again, even pierced the underground man's rocky cold and hard shell, as if to perceive their indifferent appearance, truly existing fear, nervousness, confusion, even a little... Expectation?

Li Jialing continued: “In fact, such simple questions do not need to be asked at all, just think about it and you will know - if the fabric components sold to them are not so bad, the two ends will be broken in three days, but the excellent products used on the ground, even qualified products, can be used steadily for a long time. Isn't there a little problem with the oxygen supply deep beneath the ground?

“There's no problem with oxygen, there's some rock worms, it's totally self-sufficient here. How can you control five digit towns like 10084? How can you use a tiny can of compressed air for dozens or hundreds of rock worms? ”

Li Yao's eyes slowly cooled.

Li Jialing smiled bitterly: “After six months of worry-free, heartless life, I seem to go back to the days of fighting with Li Lingfeng, Wu Yinglan, Dou Ji Douyong, every second to excite the brain cells to the limit, and see the taste of everything so clearly, it's really... painful! ”

Li Yao stopped talking, kneeling on one knee in front of Air Circulation Fabao, his eyes slightly squinted, listing the materials in his Qian Kun precepts deep in his brain, as well as repair and post-maintenance programs.

Repair the air circulation treasure, it is a small dish for a master like him who can repair even giant soldiers.

Yet Li Yao spent enough five minutes thinking, polishing the whole package with the utmost caution and finesse, and then solved the problem, using the entire hour to quench all the mandarin components together. Those unusable scrap copper and rotten iron were simply thrown aside, in exchange for the celestial treasures he had cheated from Li Linghai, and at all costs consumed the still extremely weak Numen, with the three-dimensional microsculpting method of molecular grade number, to reorganize the entire circulation and purification system.

As for the conversion of carbon dioxide into oxygen, there is no finished product in his Qian Kun ring. Good thing the formulation is not complicated. Li Yao eyebrows are not half wrinkled. With several kinds of coolants and combustion aids even worth the city, a barrel is synthesized locally. With the consumption of all residents of District 10084 plus rock worms, support should be fine for two or three years.

“Done! ”

Li Yao looked at the shiny, shiny Fabao component and smiled slightly, gently closing the cover of the core unit and fine-tuning the running character array next to it.

Suddenly, a fresh and cool air erupted from the "Big Tree” into the branches and root system that stretched all over the town, like a brisk, leached rain on a hot summer afternoon.

Many underground people have been careful to spy on Li Yao's movements in the distance, neither dare to go forward nor know what exactly he is doing. Until this moment, he realized that he could not believe what his eyes and skin felt, but he was eye-knotted and stuck like a wooden chicken.

For a long time, perhaps thousands of years, starting with the ancestors of their ancestors, they did not know what it was like to be “ecstatic”. Realistic darkness and embarrassment even forced them to accept Longyang's “kindness” and renounce feelings of pain and despair.

But now, the long-established brain suddenly bursts with stiff, twisted, weird expressions on their faces, sour, sweet, bitter, salty, a flower blooming hesitantly on the faces of men, women and the elderly, they were all like drunk, slurping, hand and foot dancing.

“Ladies and gentlemen, I have just repaired your air circulation system, gradually restored the oxygen content in the air to normal levels, and purified the toxicity in the air. You have been used to living in low oxygen concentrations for a long time. Suddenly, the increase in concentration will cause ‘drunken oxygen', but it will not affect you in half, it will only make you smarter and stronger, don't be nervous! ”

Li Yao straightened his waistplate again, regardless of whether the underground people could understand him or not, and then believed him or not, just looking out loud, "I find that the overall cooling system in this town also has many hidden dangers, and when I return from deeper underground, I will definitely help you repair it, after that, I will write the entire repair and maintenance process into the Operation Manual, and you can repair and maintain it yourself--trust me, it is not complicated.

“But for the sake of safety, you'd better pick out the two most flexible and hands-on representatives, and I'll teach them my hand first, and then they'll teach it to everyone, so that you don't have to work so hard to breed rock worms in exchange for insignificant compressed air, and you don't have to be peeled off by higher plates! ”
