The middle-aged man was very talkative, and Su Chen also cheered up, repeatedly inquiring about the information he wanted to know without a trace, and soon had a preliminary understanding of these undersea cities, and also had a preliminary understanding of the "division of labor and cooperation" in the mouth of the middle-aged man.

However, this clear understanding made Su Chen feel that sometimes it was really rare to be confused.

A sober person is always much more painful than a person who is kept in the dark.

These different human cities have their own characteristics and origins, but they have one thing in common, that is, they are committed to maintaining the living environment of these cities and reproducing perfect genetic people.

It can be said that for the human beings in these cities, the meaning of their existence lies in this.

Human beings seem to have an inherently "self-centered" attribute, and even people with extremely low self-esteem to the point of harboring a deep sense of inferiority have a deep-seated "self" that cannot be offended.

For Su Chen, this non-offensive self is "freedom".

And for the human inhabitants of these undersea cities, this sacred realm that cannot be offended is the mission of reproducing perfect human beings.

Those perfect human beings live in the core of these undersea cities.

Humans, with varying degrees of genetic defects, are centered on the core area of the undersea city, drawing a pie outward in a circle.

If we say that they are numbered, then the number of the perfect gene person is A-class human, the human with the second-level gene is the B-class human, and the human with the next level of genes is the C-class human.

They became pariahs in the deep waters.

Of course, for the sake of their lives, the undersea city thoughtfully performed surgery on them to implant gills that could breathe in the water before banishing them.

to make sure they don't get thrown out of these underwater cities and drown right away.

However, the pressure of the deep sea, along with a variety of large, medium and small predators and poisonous creatures, still takes the lives of many "untouchables".

They have even lost their way of life as human beings, and instead swim around in the water like fish. Gather seaweed and aquatic weeds, and hunt some of the weaker critters......

They became a new type of sea creature.

A creature that has lost its most important weapon, intelligence, and instead relies on its flesh to clumsily fight other creatures.

They are often the losers in this kind of battle for survival, but there are also some human beings, either lucky or unlucky, who have survived one crisis after another.

Hide in a cave in the mud and sand of the deep sea.

Live without the slightest dignity.

The humans protected by the underwater city do not consider these exiled humans to live as new creatures under the sea as their own compatriots.

Of course, because of their mating and breeding activities with other species, some of the survivors of these exiled humans developed fins and tails, some grew webbed hands and feet, some grew toad-like bumps and bubbles on their bodies, some covered the surface of their skin with fine silver scales, and some grew defensive spikes between their fingers, and even on their ribs and thighs...... They are also becoming less and less human.

Su Chen listened to this, trying to suppress the desire to vomit in his stomach, he knew that his face was getting whiter and paler.

However, thanks to the great Molantoxin, if it weren't for the zebra stripes on this face, it is estimated that the chattering middle-aged man opposite would have discovered that something was wrong with him.

Su Chen didn't want to listen to it anymore, but he had to restrain his feeling of nausea and maintain his superficial demeanor, so he really couldn't spare time to interrupt the enthusiastic speech of the middle-aged man......

Su Chen felt that the man was a little pitiful, and those humans who were banished outside the undersea city were of course even more pitiful.

However, he could only sigh secretly, if he really wanted to solve the problem of so many human beings surviving at the bottom of the sea...... He couldn't think of anything he could do.

Before Su Chen came here and saw this, he had been practicing the "Rejuvenation Technique" and learning the art of talismans for his luck, and he was a little complacent.

However, seeing this tragic scene here—the key is that the person concerned does not feel miserable, but takes it for granted, Su Chen felt a little bitter for his laziness for the first time.

If he had been as capable as those who had fixed a city to the back of a giant tortoise, would he have been able to prevent such a tragedy?

Su Chen couldn't suppress this thought.

Although he knew that even if he had the power of that great power now, he would not be able to save the lives of these untouchables in the water.

It is their own countrymen who have banished them.

And it is they who accept this outcome.

If they hadn't agreed with this genetic grading system in the first place, they probably wouldn't have been swept out of the house one day.

If they are not human beings who have pursued the reproduction of perfect genes from the beginning, such so-called "imperfect genes" or even "defective genes" human beings can live well.

At least as a human being, you can live an ordinary life.

However, reality turns out that they have already made their choice.

Even if they had the ability to turn back the clock and take these humans back to the days before they founded the Underwater City, they would probably still be on the same path.

Su Chen felt a deep sadness and a trace of fear.

I remember that before the upheaval of the world, Blue Star was also implementing a similar "perfect gene" plan.

Use the gene pool of the all-blue star people to screen out the most perfect genes, and based on this, through cloning and artificial intervention and reproduction, they want to create humans with perfect genes.

This plan has only been carried out for a few years, and before it has had time to achieve any phased results, it has caught up with the drastic changes in heaven and earth.

Su Chen suddenly felt that from this point of view, the drastic changes in heaven and earth were not a kind of luck for the Blue Star people.

It is better for compatriots to go into exile in the universe together, to find new planets, to cultivate new lands, and to build new homes, than to divide themselves into different "species" in this way.

Su Chen was in a heavy mood, and really wanted to change the topic, so he inquired about the previous 100-person volunteer delegation.

"Are you talking about the new residents who came before you?"

The middle-aged man may really not have met a suitable chat partner for hundreds of years, not only knows everything, says everything, says whatever he asks, but also can play a big role without waiting for Su Chen to ask carefully.

However, after listening to the middle-aged man's introduction, Su Chen felt that his mood seemed to be even heavier. This time, he didn't feel sick to his stomach, but he felt as if a big stone had been pressed on his heart, and he was almost out of breath when it fell.
