"A five-digit area!"
Li Yao was slightly surprised.
Although he felt from the dull air that he must be very deep below the sea level, he did not expect that it would be so ridiculously deep.
Any habitable planet with relatively stable geological conditions and suitable for human reproduction and reproduction often has a triple structure composed of core, mantle and crust, and Celestial Star is naturally 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, which is thirty to fifty kilometers thick, is a thin layer of "eggshell."
Even though the earth's crust is only a thin layer, it is the main area where humans live and collect resources underground.
Further down in the earth's crust, in the mantle, there may be magma with high temperature and high pressure.
Drilling a small hole at will will cause the magma to erupt and destroy everything; or there may be rock formations with a density higher than super alloy steel plates.
Even the most advanced earth-drilling magic weapons will Even after consuming astronomical amounts of spiritual energy, How deep can we drill?
In addition, the energy released by earthquakes is often dozens or hundreds of times higher than the energy released by mankind's most powerful crystal bombs, and the destructive extrusion of plate movements And the power of tearing is not something that any strong human can resist.
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 through thousands of planets in three thousand worlds, they still only scratch the surface of the "egg shells" on the surfaces of these planets.
Not yet, there seems to be 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 based on altitude and degree of civilization development.
The first level is a city with a name on the ground.
For example, the central government district where the Senate is located is named after the founding emperor and is known as "Black Star City".
There is also the heavy industry magic weapon refining center "Shiraishi Special City" where Li Yao and Long Yangjun once fought fiercely.
In short, as long as it has a name, it is usually a megacity where immortal cultivators dominate and are highly civilized and developed.
Although the underground towns have no names, only numbers, the difference can be seen based on the size and digits of the numbers.
From "0" to "9", there are a total of ten underground towns numbered with single digits.
They are dotted with the most important underground battle forts and military fortresses in the imperial capital.
They have all kinds of magic weapons, fuel and training facilities.
The defense system is even better than that on the ground.
The city must also be fortified.
When a powerful enemy attacks and the ground cannot support it, most of the immortal cultivators can retreat underground and continue to resist.
From District 10 to District 99, these double-digit towns are often the areas where down-and-out cultivators and intellectual workers live.
There are also various large public facilities, such as hospitals, schools, and underground facilities.
Ventilation base stations that deliver fresh air are often located 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.
When it comes to the fourth-level underground areas from Area 100 to Area 999, that is The lower-class towns where industrial workers and manual workers live are simply unable to support the existence of large hospitals.
However, the three-digit areas where industrial workers and lower-class laborers live are not yet the most miserable and barren areas.
Under their feet, in the underground mines and rock formations more than five thousand meters deep, there are four- 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 them, leaving them to fend for themselves.
Li Yao was once very interested in the four-digit and five-digit areas built at least five thousand meters underground.
He tried every means to collect information in this area, but in the end he only found a few words.
It is said that the civilization of the remnants living in the abyss has long been Degenerate, even the basic intelligence is gone, just like being thrown away since childhood Abandoned in the jungle and raised by wild beasts, like "wolf children", they only have the appearance of humans, but only have the souls of wild beasts.
The existence of these unexamined and ignorant creatures just proves that "real people" and "original people" are not Being of the same species, the "original man" is essentially a beast that is very human-like, that's all.
The attitude of cultivators towards these abandoned people deep underground is like the attitude of elephants towards ants deep in the mud under their feet.
They completely treat them as if they don't exist and have no interest in even trying to trample them to death.
Unexpectedly, Long Yangjun would set her lair in a five-digit underground town.
What are the residents here who are "abandoned by civilization" like?
What is Long Yangjun's so-called "conspiracy"?
Li Yao's head began to hurt again.
He frowned slightly and climbed out of the medical pool with some difficulty.

Under Li Jialing's service, he wiped his body clean, put on his Mustard Seed combat uniform, and put on all the Qiankun rings to ensure that the crystal armor could be used at all times.
After activating and colonizing the state, he became energetic and asked: "What kind of place is this place?
Where did Dongfang Mingyue go?"
"I don't know how to describe it.
I have always lived on the ground and on starships.
I never knew that such a place existed in the civilized world, and that human beings lived in such a way."
Li Jialing hesitated for a long time and didn't know what to say.
He just said, "Anyway, Brother Yao is awake now.
Take your time and take a look at it.
That...
Sister Dongfang specially told her when she left that no matter where Brother Yao wants to go, he can go and see it."
Everything is open, it doesn't matter if you want to go to her, in short, everything is free.
"But don't worry about it for now.
Brother Yao, are you sure you are really fine?
Do you want to use the medical magic weapon to take a photo?
Sister Dongfang told me the whole story of that battle.
I didn't expect Brother Yao to be so powerful.
To such an extent, even Black Star Emperor Wu Yingqi can be blasted away with one shot.
It’s really... really..."
Li Yao glanced at the rusty and dusty medical magic weapon beside him, shook his head and said: "No need to take a photo, I should be fine, even if I am injured, I don't care for a few days...
By the way, why are you staring at my head?
" "Nothing, nothing."
The little lion shook his head like a rattle and said hurriedly, "I just want to say, brother Yao, just take good care of yourself.
If you have any small things that require you to use your brain, careful deduction and calculation, just leave them to me.
Don't There is no need to destroy your brain cells anymore.
No matter how talented and outstanding you are, you still need to take care of yourself!"
Li Yao blinked and stared at Li Jialing with suspicion: "What does this mean?"
"It's boring, I just... told you to take care of yourself!"
Li Jialing held it in for a long time and said, "If you don't pay attention to maintenance, how will you fight against the Black Star Emperor Wu Yingqi next time?"
"By the way, speaking of this, I wonder if Dongfang Mingyue has told you yet?"
Li Yao said anxiously, "After the battle ten days ago, we have determined that your mother was killed by the Black Star Emperor Wu Ying decades ago, no, it should be more than a hundred years ago when she was exploring the emperor's tomb.
Qi's remnant soul is haunted, and it has only slowly started to show up in the past few decades.
Therefore, her original intention must not be to kill you!
" Li Jialing bit his lip, with a look that was both gratifying and sad, and said softly: "I know that if possible, I will expel the remnant soul of the Black Star Emperor from the body of Her Royal Highness the Queen!"
Li Yao shook his head and said: "Expelling him is not enough, because you are most likely the carrier he carefully prepared for himself.
If he escapes from the queen's body and enters your body, the consequences will be even more serious.
"Fortunately, the remnant soul of the Black Star Emperor should have been seriously injured in that fight.
It may be able to delay his conspiracy for a while, giving us a little breathing space to find out what he is going to do.
And figure out a way to crack it!
"But first, let's sort out how many cards we have in our hands.
Since this is Dongfang Mingyue's home base, is there a refining room with advanced facilities that can repair the Titan Soldier?"
Li Jialing shook his head quickly: "No, there is only a small weapon refiner here, which can barely repair the crystal armor, and the giant divine soldiers are powerless."
"All right."
Li Yao thought about it.
A super refining room capable of repairing giant divine weapons not only requires an extremely large space, but also requires a stable and continuous supply of powerful psychic energy.

It also needs the support of various precious resources and an entire technical team.
It is indeed not something you can have in Long Yangjun’s secret base.
"Then what's here?"
he asked helplessly.
Before Li Jialing could answer, there was a gentle knock on the door.
The person who pushed the door open was a girl wearing a gray cloak.
She had an almost transparent face that had never seen the sun.
Every trace of light blue blood vessels was clearly visible.
Her pupils were slightly red, and they instantly gathered into two.
Hong Dou, who was not used to the light, but whose delicate porcelain-like features showed no expression at all, first bowed slightly to the two of them, then placed a huge tray in front of them and said: "Dignified guests, please use it with ease. " Li Jialing thanked him, but the girl didn't say anything else, and walked out backwards with no expression on her face.
The girl has lived tens of thousands of meters deep underground for many years.
She has never been to the surface or been exposed to real sunlight in her life.
Her appearance is subtly different from the people on the ground and shallow underground.
And the tone is full of a monotonous and ethereal flavor, like the sound of water droplets on stalactites deep underground, dripping on rocks as smooth as jade, "tick, tick, tick", which is both beautiful and weird.
Li Yao pondered the identity of the girl and the habits of underground humans with great interest.
From the fact that the girl could fluently say the words "please use it slowly, distinguished guests", he knew that it was definitely not some "humanoid beast" that cultivators talked nonsense about.
Look at the huge metal tray in front of you.
It should have been a very flat industrial product, but after thousands of years of use, it is covered with pitted marks.
However, the edges are polished so brightly that they can clearly reflect light. .
On the metal tray, there is a large bowl of paste that is more viscous than rice porridge, and a fragrant pipa-shaped animal leg.
Don’t underestimate the skill of grilling the animal legs.
It can often be seen through the different complexity 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 can use dozens of cooking techniques and hundreds of seasonings must be highly developed.
