The refining of air circulation magic weapons and filter chips are very mature and reliable technologies.
Even as early as the Great Dark Age tens of thousands of years ago, people were riding starships equipped with air circulation magic weapons and galloping across the vacuum of the universe. .
No matter how the wars of the past 10,000 years have destroyed technology, this most basic refining technology has never been lost.
Even the Starry Star Federation on the edge of the Star Sea has developed to the pinnacle.
The super-large air circulation system in the Starry Sky Battle Fortress , enough for tens of millions or even hundreds of millions of people to breathe the freshest air at the same time.
The technological level of the True Human Empire is at least dozens to a hundred years more advanced than that of the Star Star Federation, not to mention many technologies in the field of air circulation.
Li Yao obtained a large amount of information on the imperial starships in the Deep Sea Dragon Palace in Li Linghai, and conducted in-depth research on the air circulation systems of these starships.
Even for a heavy-duty starship that was refined hundreds of years ago and is more than ten kilometers long, its air purification, filtration and circulation system still do not have any technical difficulties.
With a little bit of highly concentrated "conversion agent", it can generate energy.
Continuously turning the exhaust gas into fresh air, and using molecular grade "filters" to filter out various toxins in it, even when a blazing flame ignites inside the starship and releases thick black smoke and toxic mist, It will not affect the combat effectiveness of the entire starship.
The air circulation magic weapon used deep underground is slightly different from the same type of magic weapon carried on starships.
It does not pay much attention to sealing, but specifically requires high temperature resistance and vibration resistance.
This is not a big problem.
Li Yao knows several special ceramic materials.
As long as a thin layer is sprayed on the surface of the component, the heat resistance and earthquake resistance can be greatly improved.
The technology is not complicated and the cost is absolutely negligible.
Go high.
However…… In the core unit of the air circulation magic weapon used in Area 10084, all the purification chips and exchange units are rusty and strangely shaped.
The talisman arrays engraved on the surface and inside are as crooked as a child's smearing, and there is no heat insulation treatment at all.
Because it operates day and night and does not have a good ventilation and heat dissipation system, the temperature inside the magic weapon unit is extremely high.
Even a slight poke with a finger can make a shallow pit.
Such components cannot be described as "shoddy" at all, but are far behind the times.
Even with the magic component assembly line from five or even eight hundred years ago, such a poor product cannot be made.
Who knows?
In which small workshop were these things refined?
It’s no wonder that the air in the town can be fresh with such fake goods.
No wonder Li Yao smelled a dull and dirty smell from beginning to end!
Li Yao was so angry that he even felt nauseous.
For a master refiner like him, seeing such shit-like magic weapon components was simply staining his eyes and soul.
He endured his anger and straightened up.
Shout to the underground people outside: "Who purchased these magic weapon components, who installed them?
And who did they buy them from?
You have all been fooled!"
Li Yao's voice echoed in the huge cave.
It was smashed by stalactites and stalagmites, but it didn't make any waves.
Those underground people who were hiding among the stalagmites, mushrooms and fungus mist, all looking at them, looked like Like a frightened four-legged snake, it quickly retracted its head.
"It's useless, Brother Yao, stop shouting.
Except for a very small number of specialized talents trained by Sister Long, no one else will talk to us."
Li Jialing explained, "The underground people regard us as immortal cultivators, at least those who have come down from very high ground.
"For thousands of years, the immortal cultivators who came down from the surface have never brought any benefits to the people underground.
On the contrary, they have only brought slavery, destruction and disaster.
Anywhere where there are immortal cultivators, it often means that they have been found there.
Precious mineral veins and ruins mean that nearby villages will suffer!
"Over time, the fear of the people on the surface has been deeply imprinted in the flesh and bone marrow of the underground people.
The only way for the underground people to resist is to remain silent.

"This is when immortal cultivators who have had countless experiences and lessons heard that new mineral veins and relics were discovered underground, they pretended to be amiable and came to the underground, and even used the banner of His Majesty the Emperor to care about the ant people and the major sects to provide free assistance. , sending a large amount of urgently needed materials underground, but actually in order to obtain information about mineral veins and ruins from the underground population.
"After the information was obtained and the coordinates and reserves were clearly found out, the cultivators immediately turned against each other and completely destroyed the village.
All the villagers were either silenced on the spot or squeezed alive until they died.
"This kind of thing has happened hundreds or thousands of times, and the news will always leak out.
Over time, all the underground people know that talking to the people on the surface will bring disaster, so they must keep silent and keep a respectful distance."
Li Yao frowned and said, "Aren't we the distinguished guests of that 'Wangyou Goddess'?"
"It is precisely because we are Sister Long's distinguished guests that they dare to have the courage to watch us, and only the maids can say a few words to us."
Li Jialing said, "Otherwise, once ground people like us appear here, everyone might hide in the deepest part of the cave, huddled together with the rockworms and tremble!"
Li Yao sighed and his eyes pierced through the thick fog again, even piercing through the rock-cold and hard shells of the underground people, as if he could sense the real fear, tension, confusion, and even a little bit of fear under their cold appearance.
……expect?
Li Jialing continued: "Actually, there is no need to ask them such a simple question.
If you think about it carefully, you will know that if the magic weapon components sold to them are not so clumsy and will break every three days, but are high-quality products used on the ground or even qualified If the product can be used stably for a long time, wouldn't there be no problem with the oxygen supply deep underground?
"There is no problem with oxygen, and there are plenty of rockworms.
This place is completely self-sufficient.
How can the three-digit and four-digit towns above control a five-digit town like District 10084 with a small can of compressed air?
How about just dozens or hundreds of rockworms?”
Li Yao was slightly startled, and his eyes gradually became cold.
Li Jialing smiled bitterly and said: "Relying on the omnipotent Brother Yao, after living a carefree and careless life for half a year, I seem to have returned to the past and competed with Li Lingfeng and Wu Yinglan, fighting wits and courage, every day.
It’s a day when my brain cells are stimulated to the limit every second.
It’s so uncomfortable to see everything so clearly!”
Li Yao stopped talking and knelt on one knee in front of the air circulation magic weapon.
He narrowed his eyes slightly and listed the materials in his Qiankun Ring, as well as the repair and later maintenance plans in the depths of his mind.
Repairing the air circulation magic weapon is really a piece of cake for a master like him, who can even repair giant divine weapons.
But Li Yao spent a full five minutes thinking about it, polishing the entire plan with the most careful and meticulous attitude.
Then, he used all his strength to temper all the magic weapon components for a full hour. really He simply threw away the unusable scrap copper and iron and replaced it with the natural materials and earthly treasures he defrauded from Li Linghai.
He also did not hesitate to consume the still extremely weak Yuan Shen to reorganize the entire cycle and purification method with the three-dimensional micro-carving method at the molecular level. system.
As for the conversion agent that converts carbon dioxide into oxygen, there is no finished product in his Qiankun Ring.
Fortunately, the preparation is not complicated.
Li Yao didn't even frown.
He used several priceless coolants and combustion accelerants to create it on the spot.
One barrel is synthesized, and with all the residents in District 10084 plus the consumption of rockworms, it should not be a problem to sustain it for two to three years.
"Done!"
Li Yao looked at the shiny magic weapon components that were as bright as new, smiled slightly, gently closed the cover of the core unit, and fine-tuned the running talisman array next to it.
Suddenly, a stream of fresh and cool air gushes out from the branches and roots of the "towering tree" that extends throughout the town, just like a light rain on a hot summer afternoon, which is as refreshing as the light rain.
Many underground people have been carefully spying on Li Yao's movements from a distance.
They neither dared to step forward to stop him nor did they know what he was doing.
Only now did they vaguely understand.
They couldn't believe what they were feeling with their eyes and skin. , but he was stunned and dumbfounded.
They have not known the feeling of "ecstasy" for a long time, perhaps thousands of years, starting from their ancestors.
The darkness and embarrassment of reality even forced them to accept Long Yangjun's "kindness" and give up.
Full of pain and despair.
But now, the long-dusted brains suddenly made waves.
Stiff, twisted, and weird expressions appeared on their faces, sour, sweet, bitter, spicy, and salty.
Flowers bloomed hesitantly on the faces of men, women, and the elderly.
They all As if drunk, he staggered and danced.

"Fellow folks, I have just repaired your air circulation system, gradually restored the oxygen content in the air to normal levels, and purified the toxins in the air.
You have been accustomed to living in low temperatures for a long time.
In areas with oxygen concentration, a sudden increase in concentration will cause the phenomenon of 'oxygen drunkenness', but it will not affect you at all.
It will only make you smarter and stronger, so don't be nervous!"
Li Yao straightened his back again, regardless of whether the underground people understood what he said or whether they believed him after understanding, he just said loudly, "I found that there are many hidden dangers in the overall cooling system of this town. , I will definitely help you repair it after returning from deeper underground.
After that, I will compile a complete set of repair and maintenance procedures into an "Operation Manual" and give it to you.
In the future, you can repair and maintain it yourself.
Trust me, It's not complicated.
"However, to be on the safe side, you'd better select the two representatives with the most flexible minds and the strongest hands-on skills.
When the time comes, I will teach them step by step, and then they will teach it to everyone.
In this way, you will never There is no need to exchange the hard-earned rockworms for insignificant compressed air, and there is no need to be exploited by higher-ups!"
