The magic dog driving in the underground tunnel at high speed is as fast as lightning, the dark rock walls on both sides are the same, only the light of the demon dog's eyes like a monster illuminates a small distance in front of it, and at the end of the day, even the lights of this car are extinguished, because with the synchronous map automatic navigation, it doesn't matter if you can see it or not.

Gao Feng and Ouya are wearing special driving helmets, they can't feel the sound of whistling outside, but they feel even more sad, Ouya has become accustomed to this kind of silent driving, but Gao Feng can't stand it, so he wants to talk to Ouya through the helmet's walkie-talkie, and as soon as he spoke, the helmet cast the image of Ouya in his pupils.

Obviously, this is a new technique, Gao Feng immediately felt that the boring call came alive, and he knew that his image at this moment also fell in the eyes of Ouya.

"Do you know the approximate population of the underground people in the Dao?"

Gao Feng asked without words, originally thought that Ou Ya, as a soldier, was not clear about these things, but he didn't expect Ou Ya to open his mouth and say.

"Underground cities are widely distributed in various areas below the ground, and as far as I know, there are 12 large cities, 27 small cities, and 59 satellite cities, with large cities starting with the word A, small cities with the word C, and then ...... D."

"Why don't you have a B?" Gao Feng interrupted Ouya's narration, Ouya's expression was slightly stunned, and he recalled:

"The B-class city used to be the main residential city of the Underground Realm, but there was a major storm forty years ago. More than 60% of B-level cities have been contaminated by the virus, and some people have proposed to withdraw the resources of B-level cities and establish A-level cities and cities below C-level, and from then on, B-level cities will not be on the list. ”

"Then ......."

Gao Feng was silent, and an idea suddenly appeared in his heart, although he was not sure, but it was very likely.

"A-level cities can accommodate a population of about 100,000 and need about 5,000 square kilometers of resources underground, and C-level cities need an area of hundreds of square kilometers to supply 5,000 to 8,000 people, because there is not much space available underground, and many scattered spaces have established small resettlement sites, ranging from hundreds to thousands of people, and are divided into D-level cities.

But I know that there are only a few cities in the Dao, many of which have been out of contact for a long time, either due to landslides and blocked roads, or occupied by very dangerous biochemical beasts, so the new underground space is the most precious, just like the closed canyon we found before, where you can enjoy the air on the ground, and you can grow trees and food, all of which are designated as the Garden of Eden, and only the top jīng Ying are eligible to live in. ”

Only then did Gao Feng understand how hard the black magic virus had dealt to the underground world, countless B-level cities were abandoned, lacking space for development, and could only barely do it for the current population, no wonder the underground has always wanted to go to the ground, but because of the unprecedented shackles of survival, this is an irreconcilable problem.

Shut down

"How is the population under control underground? As far as I know, none of you have met your own parents....... ”

Gao Feng thought of another question and asked it curiously.

"Civilians underground, who do not have the right to procreate, because of the scarcity of supplies, only the best have the opportunity to reproduce, including scientists, soldiers, athletes, artists, ......."

"Athletes? Artist? ”

Gao Feng interrupted again, he didn't expect that there were still these two professions underground.

"Athletes are the idols of the people in the underground world, they bring entertainment to the people through various competitions, and artists through their works, so that the civilization of the lower world can continue, they are some of the best people, but also the most valuable people, the offspring they give birth to will be better than ordinary people, relatively speaking, the inferior quality is much lower than the average person."

"Defective?"

There are more and more questions from Gao Feng, and Ouya naturally won't get bored and continue to explain patiently.

"The defective products are civilians, who will behave mediocre in the training camp, so they are classified as ordinary people, they are the lowest workers, and they are also the most numerous......."

Gao Feng suddenly understood that what the underground zhèngfǔ did was to artificially increase the probability of evolution, let the best people have offspring, and deprive civilians of their reproductive rights, and most people are mostly mediocre before they find their own strengths, after all, there are very few geniuses, so that many people have no chance to get ahead in their lives,

"However, the underground zhèngfǔ does not really prevent the reproduction of civilians, many unidentified black households live in the worst environment of the city, they are not recognized by the zhèngfǔ, and they cannot enjoy the rights and obligations that civilians have, they are called the hidden clan, which means a hidden race.

The punishment of the hermits in the underground world is very severe, they are not allowed to engage in any work, and they are not allowed to learn knowledge, most of them can only rely on the garbage on the periphery of the city to live, the only opportunity to give them is only two, one is to become a miner, digging poor ore that is not worth mining with large machinery, or to explore new underground space, the former requires them to spend more than ten years, or even a lifetime in exchange for a chance to become a civilian, while the latter requires them to exchange their lives for ....... ”

The most cruel side of the underground world was finally shown in front of Gao Feng, but instead of being angry, Gao Feng let out a long breath, at least the problem of his identity was solved, and it was not impossible to become a hidden clan for the time being.

"Why is there a difference between what you told me and what Mo Yuan told me?"

Suddenly thinking of this question, Gao Feng couldn't help asking.

"Mo Yuan is just a civilian, belonging to some of the people who have been eliminated, they live at the lowest level of the underground, only a little stronger than the Yin Clan, they have limited knowledge of the Dao, and they don't know much about the upper level, just like we don't know the lower level, and there is nothing strange ......about it."

Ou Ya said very indifferently, but Gao Feng sensed an inadvertent sense of superiority from her rigid face, whether the class existed in the past life or now, whether it was on the ground or underground.

"The place we went to is called A3, a big city with a population of 190,000, and the actual population capacity is only 100,000, if you count the hermits, maybe more, so, you may not get used to ......."

When Gao Feng was thinking about the follow-up plan, Ou Ya suddenly opened his mouth to remind Gao Feng, Gao Feng was slightly stunned, and asked rhetorically:

"Doesn't it mean that every city has a quota for its population?"

"There is still a difference between the quota and the actual situation, the population needs to grow to be normal, otherwise it will fall into aging, and the key is the ...... living space."

Ou Ya explained very succinctly, but Gao Feng remembered the city in his previous life, because of the war, the city that could accommodate hundreds of thousands of people was squeezed into more than one million people, causing the city's infrastructure to almost collapse, and the public facilities were also overwhelmed, resulting in the appearance of sāo chaos, turning the entire city into a hell.
