Forty Millenniums of Cultivation

“Five-digit area! ”

Li Yao was slightly surprised. Although he sensed from the dull air that he must be deep below sea level, he did not expect to be so deep.

Any inhabitable planet whose geological conditions are more robust and where humans can reproduce, often possesses a triple structure of earth cores, mantle and crust, and the celestial stars are naturally no exception.

Such a habitable planet is like a giant egg, and the earth's core is egg yolk, and the mantle is protein, and the crust, which is three or five kilometers thick, is a thin layer of "egg shell”.

Don't look at the crust as a thin layer, but as the main inhabited and resource-gathering area of humankind beneath the ground.

If you drill a small hole in the earth's crust, or a high-temperature, high-pressure magma, it will cause the magma to erupt and destroy everything; or if you drill more dense than superalloy steel plates, even the most advanced earth-boring treasures consume astronomical digital spiritual energy, it will not necessarily drill much deeper; combined with the energy generated by earthquakes, it will often be hundreds of times higher than the energy released by the most powerful crystal bombs of humankind, and the squeezing and tearing force of plate motion that destroys the heavens and the earth is not resistant by any human power.

In a nutshell, the mantle is a dangerous and inexpensive area of death. Although the tentacles of human civilization have swept the thousands of planets of the 3,000 world, it is still only palpable on the "egg shells” on the surface of these planets, and yet it is not, and does not seem necessary, to go deeper into the mantle.

In the empire of the true human empire, all towns are divided into six levels, based on altitude and civilizational development.

The first is a city with a name on the ground, such as the central government district where the Senate is located, named after the emperor of the Founding Fathers, the "Black Star City”.

There is also Li Yao and Longyang Jun's heavily fought Heavy Industry Law Treasure Refining Center “White Stone Special City”. In short, if you have a name, it is often the immortals who dominate, highly civilized mega-city.

And while the underground towns have no names, only numbers, the difference can be seen depending on the size and number of digits.

From “0” to “9”, there are ten digit-numbered underground towns filled with the Emperor's most important underground battleforts and military fortresses. There are all sorts of magic treasures, fuel and refining facilities. The defense system is even more rigorous than the ground city. When strong enemies attack and ground support cannot be sustained, the vast majority of fairy fixers can evacuate underground and continue to resist.

From District 10 to District 99, these double-digit towns, often inhabited by immortals and native brain workers, are often housed in large public facilities, such as hospitals, schools and ventilation base stations that continuously deliver fresh air to underground sources.

Oriental benevolently chose to open his secret institute in two digit towns, just because only two digit towns could support the existence of such a large hospital, waiting for a level 4 underground area such as the 100th to 999th districts, that is, the lower towns inhabited by industrial and manual workers among the original population, to be unable to support the existence of a large hospital at all.

However, the three-digit area inhabited by industrial workers and bottom labourers is not yet the most tragic and marginal.

At their feet, in underground caves and rock formations over 5,000 metres deep, there are also four- and five-digit towns that, like forgotten corners, have been completely abandoned by the elite members of the Empire's society and are not even worth squeezing and peeling, leaving them to perish.

Li Yao was interested in constructing at least four and five digit areas below 5,000 meters below the ground, trying to gather materials in this regard, but ultimately all he found was a rhetorical clip, said to be the legacy of living in the abyss, civilization had long degraded, even basic intelligence had not existed, like a "wolf child” who had been abandoned from childhood to the jungle and raised by the beast, but only the soul of the beast - these horrible, foolish creatures just proved that “real people" and “original people” are not the same class, “original people" are essentially a beast like human beings, that is all.

The attitude of fairy fixers towards these abandoned people deep beneath the ground is like the attitude of elephants towards ants deep in the sludge of their feet, when they don't exist, and they don't even have the interest to painstakingly stomp them to death.

It was unexpected that Longyang King had set her nest in a five-digit underground town. What exactly were the residents of this place “abandoned by civilization”, and what was the so-called “conspiracy” of Longyang King?

Li Yao's head began to ache again. He frowned slightly, and some of his efforts climbed out of the medical pool, wiping his body clean under the service of Li Jialing, putting on his mustard battle suit, wearing all the Qian Kun precepts, and ensuring that Jing Jian was in a state of activation and fabrication at all times. This was a thrill. “What exactly is this place, where did the Oriental Moon go? ”

“I don't know how to describe it, I used to live on the ground and on starships, I never knew that there were places like this in the civilized world, and that humans lived in this way. ”

Li Jialing hesitated for half a day and didn't know how to say it. He just said, "Anyway, now that Brother Yao is awake, look at him slowly, that is, that... when the Oriental sister left, she specifically ordered him to go wherever he wanted, to see whatever he wanted. It doesn't matter if he wants to go to her, everything is free.

“But don't worry about it, Brother Yao, are you sure you're okay? Do you want to take another photo with the medical treasure? Sister Oriental told me the whole story of the war. I didn't expect Brother Yao to be so powerful that even Black Star Emperor Wu Yingqi could go off with a single shell. Really... Really...”

Li Yao swept the rusty, dusty medical treasure next to him and shook his head: “No need to take a photo, I should be fine, even if there are injuries, I don't care for these days... what are you staring at in my head? ”

“Nothing, nothing. ”

Little Lion shook his head like a wave drum, rushed, “I just want to say, Yiu brother, despite good injury care, what do you need to start your brain, carefully deduce and calculate small things, just leave them to me to handle, no more need to destroy your brain cells, even though you are so talented and brilliant, care must be taken! ”

Li Yao blinked and stared at Li Jialing with suspicion: “What does this mean? ”

“It's boring, just... tell you to take care of it! ”

Li Jialing held his breath for half a day. “If you don't pay attention to maintenance, how do you fight Black Star Emperor Wu Yingqi next time? ”

“By the way, speaking of which, I wonder if the Oriental Moon has told you--”

Li Yaoqi said, “After the battle 10 days ago, we have determined that your mother was not right decades ago. It should have been more than a hundred years ago when she explored the Emperor's tomb, she was haunted by the wreckage of Black Star Emperor Wu Yingqi. It was only in recent decades that she slowly seized, so, in her intention, she must not really want to kill you! ”

Li Jialing bit his lips, and his divine color was both comforting and dark. He said softly: "I know that if possible, I will surely expel the remains of the Black Star King from Her Majesty's body! ”

Li Yao shook his head: “Expulsion alone is not enough, because you are most likely the carrier he has carefully prepared for himself. If you escape from the Queen's body, you will enter your body, and the consequences will be even worse.

“Fortunately, the Dark Star Emperor's soul should have suffered a lot in that struggle, which is expected to slow down his conspiracy trick for a while, allowing us a little breathing space to find out what he was really up to and figure out a way to break it!

“But first, let's sort out how many cards we have - since this is Oriental Moon's nest, is there an advanced refinery room that can repair giant soldiers? ”

Li Jialing shook his head quickly: “No, there is only a small refinery room here, barely able to repair the crystal armor, there is nothing the Giant Divine Soldier can do. ”

“Okay.”

Li Yao also imagines that the super refinery room that can repair the Giant Divine Soldier requires not only a huge amount of space, but also a stable and continuous supply of powerful spirits, as well as a variety of precious resources and the support of an entire technical team. Indeed, it is not what Longyang King's secret base can have.

“What do we have here? ”

There was nothing he could do to ask.

Li Jialing hasn't answered yet, there is a gentle knock outside.

Pushing the door was a young girl in a gray cloak, with a face that had never seen the sun, almost transparent, a slight blue blood vessel, slightly reddish pupils, instantly gathered into two red beans, not very comfortable with the look of the light, sophisticated like five organs of porcelain without showing a half-point expression, first bowing slightly towards two people, then placing a huge tray in front of two people, said: “Please enjoy. ”

Li Jialing thanked her. The young girl did not say anything else. She walked out with no expression on her face.

Over the years, the teenage girl has lived in the ground tens of thousands of metres deep, has never been to the ground in her life and has come into contact with the real sun, and her appearance has been subtly different from that of people on the ground and in the shallow ground.

And the tone is more monotonous and airy, like a droplet of water on a bell milkstone deep beneath the ground, dropping on a rock as smooth as a jade, “Tick, tick, tick, tick, tick," which is both nice and weird.

Li Yao Rao pondered with interest the identity of the teenage girl and the habits of the underground humans - from the ability of the teenage girl to fluently say, "Please enjoy the VIP”, he knew that it was by no means a "human beast” that the immortals were talking nonsense.

If you look at the huge metal tray in front of you, it should have been a very flat industrial product, but for thousands of years it was covered with pit depressions, but the edges were polished with bright brightness and clearly reflected light.

Above the metal tray is a large bowl of paste that is thicker than rice congee, and there is also a nose-pounding walnut-shaped leg - don't underestimate the craftsmanship of the BBQ leg, which can often be seen in the level of development of a civilization through the simplicity of food processing.

The barbarian race of boiled blood is by no means proficient in cooking, and a civilization that employs dozens of cooking techniques and hundreds of spices must be highly developed.
