Chapter 2341 The Forgotten Land

"Five-digit area!"

Li Yao was slightly surprised. Although he could feel that he must be very deep below the sea level from the dull air, he didn't expect it to be so ridiculously deep.

Any habitable planet with relatively stable geological conditions for human reproduction often has a triple structure consisting of the core, the mantle and the crust, and Tianji Star is no exception.

Such a habitable planet is like a huge egg, the core is the yolk, the mantle is the egg white, and the crust with a thickness of 30 to 50 kilometers is a thin layer of "eggshell".

Although the earth's crust is only a thin layer, it is the main living and resource gathering area for humans underground.

In the mantle below the earth's crust, or in the high-temperature and high-pressure magma, drilling a small hole at random will cause the magma to erupt and destroy everything; or in rock formations with a density higher than superalloy steel plates, even the most advanced earth-drilling magic weapon, Consuming an astronomical amount of psychic energy may not be able to drill very deep; in addition, the energy released by the earthquake is often dozens or even hundreds of times higher than the energy released by the most powerful spar bomb of mankind, and the plate movement is so powerful. This crushing and tearing force cannot be resisted by any strong human being.

In a word, the mantle is a dead zone that is both dangerous and lacks cost-effective mining. Even though the tentacles of human civilization have swept thousands of planets in the three thousand worlds, they still only have a taste of the "egg shells" on the surface of these planets. Not yet, and it seems that there is no need to go deep into the mantle.

On Tianji Star, the imperial capital of the True Human Empire, all towns are divided into six levels according to the altitude and the degree of civilization development.

The first level is a city with a name on the ground. For example, the central government area where the Senate is located is named after the founding emperor's title, known as "Black Star City".

There is also the "Baishi Special City", the heavy industry magic weapon refining center where Li Yao and Long Yangjun fought fiercely. In short, as long as it has a name, it is often a megacity with a high degree of civilization and development where immortal cultivators occupy the mainstream.

Although the underground town has no name, only a number, but the difference can be seen based on the size and number of digits of the number.

From "0" to "9", there are a total of ten underground towns numbered in single digits. There are the most important underground battle forts and military fortresses in the imperial capital. There are all kinds of magic weapons, fuel and training facilities. The city is even more fortified. When a strong enemy strikes and the ground cannot support it, most of the cultivators can retreat underground and continue to resist.

From the 10th district to the 99th district, these double-digit towns are often the areas where down-and-out immortal cultivators and mental workers among the original people live, as well as various large-scale public facilities, such as hospitals, schools, and underground Ventilation base stations that deliver fresh air are often set up here.

Dongfang Renxin chose to open his secret research institute in a double-digit town, because only a double-digit town can support the existence of such a large-scale hospital, and wait until the fourth-level underground area from the 100th to the 999th area, that is, The low-level towns where industrial workers and manual workers lived among the original people were simply unable to support the existence of large hospitals.

However, the three-digit areas where industrial workers and low-level laborers live are not the most miserable and barren areas.

Under their feet, in the underground mines and rock formations more than five kilometers deep, there are four-digit and five-digit towns. These towns are like forgotten corners, completely abandoned by the upper class of the empire, and even There is no value in squeezing and exploiting, let them fend for themselves.

Li Yao was very interested in the four-digit and five-digit areas built at least five kilometers below the ground. He tried every means to collect materials in this regard, but in the end he found only a few words. It is said that the survivors living in the abyss have long been civilized. Degenerated, even basic intelligence is gone, just like a "wolf boy" who was abandoned in the jungle and raised by wild beasts since he was a child. He only has the appearance of a human, but only the soul of a beast. The existence of living beings just proves that "real people" and "original people" are not of the same race, "original people" are essentially a kind of beast that is very similar to human beings, that's all.

The attitude of the cultivators towards these abandoned people deep in the ground is like the attitude of an elephant towards the ants deep in the mud under their feet. They completely treat them as if they do not exist, and they are not even interested in trampling them to death.

Unexpectedly, Long Yangjun set up her lair in a five-figure underground town. What are the "abandoned by civilization" residents here, and what is Long Yangjun's so-called "conspiracy"?

Li Yao's head started to hurt again, he frowned slightly, climbed out of the medical pool with some difficulty, wiped his body clean under the service of Li Jialing, put on the mustard seed combat uniform, put on all the universe rings, and ensured that the crystal armor was always in good condition. In the state of activating and growing the equipment, he was refreshed and asked: "What kind of place is this place, and where did Dongfang Mingyue go?"

"I don't know how to describe it. I have been living on the ground and on starships before. I never knew that such a place exists in the civilized world, and that humans live in... this way."

Li Jialing hesitated for a long time and didn't know what to say, he just said, "Anyway, brother Yao is awake now, just watch it slowly, that... Sister Dongfang specifically told you when she left, no matter where Brother Yao wants to go, you can watch it if you want Everything is open, and it doesn't matter if you want to find her, in short, everything is free.

"However, don't worry about it so much. Brother Yao, are you sure you're really okay? Do you want to take another photo with a medical magic weapon? Sister Dongfang told me the whole picture of that battle. I didn't expect Brother Yao to be so powerful. To such an extent, even the Black Star Emperor Wu Yingqi can run away with a cannonball, really... really..."

Li Yao glanced at the rusty and dusty medical magic weapon next to him, shook his head and said, "There's no need to take a photo, I should be fine, even if I'm injured, I don't care about these few days... By the way, why are you staring at my head all the time? "

"Nothing, nothing."

The little lion shook his head like a rattle, and hurriedly said, "I just want to say, brother Yao, you can take good care of your wounds, and if you have to use your brain, carefully deduce and calculate all the small things, just leave it to me to deal with it. There is no need to destroy your brain cells anymore, no matter how talented and outstanding you are, you must pay attention to maintenance!"

Li Yao blinked, staring at Li Jialing suspiciously: "What does this mean?"

"It's boring, I just... tell you to take care of it!"

Li Jialing held back for a long time and said, "If you don't pay attention to maintenance, how will you fight against Black Star Emperor Wu Yingqi next time?"

"By the way, speaking of this, I wonder if Dongfang Mingyue told you?"

Li Yao said anxiously, "After the battle ten days ago, we have confirmed that your mother was killed by the Black Star Emperor Wuying decades ago, no, it should be more than a hundred years ago when she was exploring the emperor's ancient tomb." Qi's remnant soul is entangled, and it only happened slowly in the last few decades, so, in her original intention, she must not really want to kill you!"

Li Jialing bit his lip, his expression both gratified and sad, and said softly: "I know, if possible, I will definitely expel the remnant soul of the Black Star Emperor from Her Royal Highness's body!"

Li Yao shook his head and said, "It's not enough just to be expelled, because you are most likely the carrier he carefully prepared for himself, if you escape from the Queen's body and enter your body, the consequences will be even more serious.

"Fortunately, the remnant soul of the Black Star Emperor must have suffered a lot of injuries in that fight. It is estimated that it can delay his conspiracy for a while, and give us a little breathing room to find out exactly what he is going to do. And come up with a solution!

"But first, let's sort out how many cards we have in our hands. Since this is Dongfang Mingyue's old lair, is there a refining room with advanced facilities, the kind that can repair giant god soldiers?"

Li Jialing shook his head quickly: "No, there is only a small craftsman here, who can barely repair the crystal armor, and the giant soldiers are helpless."

"All right."

Li Yao thinks about it too. A super refining room capable of repairing giant weapons requires not only an extremely large space, but also a stable and continuous supply of powerful spiritual energy, as well as various precious resources and the support of an entire technical team. It is indeed not something that Long Yangjun's secret base can have.

"Then what's here?"

he asked helplessly.

Before Li Jialing could answer, there was a light knock on the door outside.

The one who opened the door was a girl wearing a gray cloak, with a face that had never seen the sun before, almost transparent, with traces of light blue blood vessels fully visible, the pupils were slightly red, and instantly gathered into two. Hongdou, who was not used to the light, showed no expression on her porcelain-like facial features, first bowed slightly to the two, then placed a huge tray in front of the two, and said: "Please take it easy, distinguished guest. "

Li Jialing thanked her, but the girl didn't express anything else, and walked out backwards with a blank expression.

The girl has lived tens of thousands of meters deep underground for many years. She has never been to the ground or exposed to real sunlight in her life. Her appearance has been subtly different from the people on the ground and shallow underground.

And the tone is full of a monotonous and ethereal taste, just like the sound of water droplets on stalactites deep in the ground, dripping on smooth jade rocks, "tick, tick, tick", which is both nice and weird.

Li Yao pondered the girl's identity and the habits of the underground humans with great interest. From the girl who can fluently say "please use it slowly", he knew that it was definitely not some kind of "humanoid beast" nonsense talked about by immortal cultivators.

Looking at the huge metal tray in front of me, it should have been a very flat industrial product, but it has been used for thousands of years. It is full of potholes, but the edges are polished so that it can clearly reflect the light. .

On the metal tray, there is a large bowl of paste thicker than rice porridge, and a fragrant pipa-shaped animal leg. Don’t underestimate the craftsmanship of barbecued animal legs. You can often see the difference in the complexity and simplicity of food processing methods. The level of development of a civilization is high.

It is impossible for a barbaric race that drinks blood to be proficient in cooking. A civilization that uses dozens of cooking techniques and hundreds of seasonings must be highly developed.
