"Do you know what they are?" Alice answered Leo's question again, and immediately felt keenly that Leo seemed to know something.

In fact, the scholars of Lan Xi City had also studied these clans that had mutated after being infected by the power of the abyss for a long time, and even invited the church in the divine realm where these clans were previously located to participate, but they found nothing.

No matter how strange these mutant clans were the clans of the gods in the first place, but once they were infected by the power of the abyss and mutated, they would unify into the kind of special existence with a skeleton body like a bone butterfly.

The reason why these mutated clans infected by the power of the abyss are allowed to exist here now is that after their repeated research, they found that this kind of clan will not attack them, but will purify the power of the abyss that is difficult to clean, so Lan Xi City placed this kind of clan in the area where the entrance to the abyss is located, specifically to spread the power of the abyss.

However, after all, these mutant clans are all mutant species after being infected by the power of the abyss, and the people of Lanxi City know very well how dangerous those monsters who mutate after being infected by the power of the abyss will be, so the monitoring of these mutant clans has never weakened, and they still have not stopped studying these mutant clans, and their attention has always been at the forefront of various proposals.

Now, Leo's attitude made Alice feel that Leo seemed to know the origin of this mutant family, which made her wonder, not only curious why Leo knew so many abyssal species that even the various gods of the Black Forest didn't know, but also curious about what was so special about this mutant family.

However, Alice was destined to be disappointed, and Leo just smiled and said nothing, obviously the matter about the Ash Butterfly had been used by him as a bargaining chip that could be used for trading, and it was obviously impossible to say it like this.

Seeing Leo's attitude, a look of disappointment flashed in Alice's eyes, but she didn't ask any more questions, and sat quietly in the car, and the atmosphere in the car fell into an awkward silence again.

After Sylvia entered this area, she immediately felt the abyssal aura permeating this city, and her heart felt like she was at home, and her whole person fell into a state of almost light sleep, while the power contained in her blood slowly adjusted her body to adapt to this environment.

Leo naturally noticed that Sylvia was out of the ordinary, but he quickly checked Sylvia's condition and didn't find anything wrong, so his main attention shifted to the speed car.

Compared to the previous buildings in the city, the core area of the Prometheus where the entrance to the abyss is located is much more ordinary, there are no strange buildings with prominent shapes, and all of them are bunker-shaped energy batteries.

Compared with those high-rise buildings, these batteries are much lower, the highest is only three or four stories high, and these batteries are large and small, the large ones can see the barrels of more than a dozen energy cannons sticking out from the windows in all directions, like a big hedgehog, and the small batteries can also accommodate three or four energy cannons.

These forts are densely packed throughout the quasi-safe areas of the city, and they look like wrinkled skin.

In addition, not only are there so many turrets on the ground, but even the dome above has built a large number of turrets, and the barrels of these turrets are all aimed in the direction of the entrance to the abyss.

Although these ground and dome batteries appear to be the same type of batteries in terms of the shape of the barrels, in fact the ground batteries are artificial batteries, and a large number of mecha sergeants can be seen entering and exiting these batteries, while the batteries on the poor top are all automatic batteries, controlled by an automatic fire control system.

In addition to the human factor, the difference between the upper and lower turrets is also in the surface of the turret, the dome turret is the same as the common turrets of Leo before, the outside is a layer of defensive armor, and the inside is a variety of components, while the surface of the turret on the ground is a layer of divine words containing mysterious power, which will undoubtedly protect the people inside the turret from the erosion of the power of the abyss.

Because the flying car was flying at a low altitude after entering this area, Leo could not see the full view of the entrance to the abyss, and could only see a huge crater in front of him, which was large enough to swallow a small town.

From the center of the crater, a black oily mist gushes out, and after flying one end in the air, it spreads out in all directions.

And when the black gas mist condensed by these abyssal breaths dispersed to the edge of the pit and tried to escape to the surrounding area, a burst of gray light belonging to the mother of filth immediately shone on the empty ring clearing at the edge, swallowing, guiding, and transforming these black gas mist, and finally collected into the surrounding small pools.

The ash butterflies gathered around the pool, sprinkling some ash that landed on the black oil in the pool and immediately melted it away.

"That's the entrance to the abyss, right?" At this time, Sylvia, who had already adapted to the aura of the abyss around her, also returned to normal, and asked in a deep voice after seeing the black gas mist gushing out of the entrance of the abyss through the window.

"Yes. Alice nodded, and asked Sylvia with some concern, "How are you feeling now?"

"Very well, never before!" Sylvia replied categorically, and then said with a little puzzlement, "Are there similar fortifications laid out underground?"

Alice shook her head and said, "No." Any questions?"

Sylvia asked, "Since there are only fortifications on the ground, why don't the monsters that come out of the abyss be inside the entrance and dig a hole in the ground to avoid the fortifications on the ground?"

"This ......" Alice didn't know how to answer for a while, because not to mention her, even the scholars in Lanxi City probably hadn't thought about it, and now that Sylvia had mentioned it, it made her have bad associations.

As Sylvia said, all the fortifications are arranged on the ground part, and she can be sure that there is no arrangement in the underground part, because if there is an arrangement, it must be maintained, and only these fortifications on the ground have been maintained countless times over the years, and I have never heard of a fortification underground.

Thinking of this, Alice couldn't help but feel a chill in her back, and a cold sweat broke out, because Sylvia's words were equivalent to demolishing their defenses here, and there was a huge loophole in the abyss, and the monsters that poured out of the abyss could run out of this loophole at any time, and maybe even a large number of abyssal monsters had run out in the past so many years.

However, just when Alice felt flustered, Leo on the side seemed very calm, and took the initiative to answer: "Don't worry about this, as long as there are no loopholes in the fortifications on the ground, it is impossible for those monsters to avoid the fortifications and open a passage underground." ”

"Why not?" asked Sylvia.

"Because the entrance to the abyss that we see is not a hole in your common sense, it is just an entrance, like an entrance to the forest of Luxe. Leo tried his best to explain the state of the entrance to the abyss in the simplest sentences that Sylvia could understand, although it would be more complete and accurate to explain it with concepts such as spatial wormholes, but it would inevitably use a lot of words from the Earth Federation, and they would only feel more at a loss when they heard it.

Although the two still didn't understand Leo's explanation, and it wasn't clear why Leo was so sure that the monsters of the abyss wouldn't dig holes, they still chose to believe Leo, Sylvia believed Leo because of emotions, and Alice thought that Leo knew a lot about the secrets of the world.

The car quickly flew over the defensive position and landed in front of a nondescript looking artillery courtyard near the edge of the defensive position.

At the same time as the flying car fell, Xivini Belmont led several mecha sergeants with a stack of documents in her hand, and when she walked to the side of the flying car, she couldn't help but be stunned when she saw Leo and Sylvia getting out of the car, and the words she was going to say to Alice stopped at her throat.

At this time, Sylvia also saw her sister, who had been taken away since she was a child, although she had dealt with her before, and the process was not very pleasant, but now she saw each other again, and understood her identity and relationship with the other party, and she didn't know how to say anything to her for a while.

Because Sylvia didn't hide her emotions at all, Sylvia Belmont noticed something, and looked at the other party with some confusion, not understanding why the other party looked at her with such a look.

As for Leo having no intention of intervening in the sisters' affairs, or even what Sylvia was going to do with Alice, he had no intention of interfering unless necessary.

The moment he got off the flying car, Leo's attention fell on the mech-sergeants who were following Sevinie Belmont, as he developed a sense of familiarity from them.

"Cyborg Warrior!" Leo immediately had an answer in his heart as he felt his memories evoke, and his face became gloomy at this moment.

Although the life of a cyborg in the Earth Federation occupies the vast majority of his current life, and it is also the foundation for him to be able to gain a foothold in this world, he does not have any good feelings about that life experience, especially after he has gradually become accustomed to the emotions that ordinary people have, he feels more and more that his life as a cyborg is simply like hell, so he prefers to treat that memory as a material archived in the database, and will not read it if it is not necessary.

However, now he saw the shadow of cyborg warriors on these mecha sergeants, and felt the indifference unique to cyborgs from the other party's eyes, which also meant that these mecha sergeants should have undergone some surgeries that cyborgs would only do before they were born, and it was still an incomplete operation.

Thinking of this, Leo suddenly recalled an anti-human technology before the Earth Federation began to mass-produce cyborgs and replenish a large number of consuming soldiers, and this technology also indirectly led to the emergence of cyborgs.

At that time, the Earth Federal Government had many enemies in the universe, so they had to send a large number of soldiers to defend the four directions, but with the emergence of various wars, there was also a shortage of soldiers, and the age of joining the army was also reduced again and again, and finally reduced to the extent that teenagers must also join the army.

Although these teenagers have experienced all kinds of military training, they are still some fledgling teenagers after all, and many things can not be possessed through training, such as combat awareness, such as combat emotions, and so on.

During this time, there were a large number of accidents in the army of the Earth Federation, and most of these accidents were caused by the panic of those new recruits who joined the army, and the losses were extremely heavy.

To this end, the Earth Federation passed a secret bill to strip away the emotions of those recruits to a certain extent through some surgeries, so that these recruits always maintain a high will to fight, and reduce the panic, fear, and other emotions that will be unfavorable to the battle.

After the implementation of this secret law, the effect was remarkable, the various things caused by the panic of the recruits were reduced to zero, and the overall combat effectiveness became similar to that of veterans who had experienced more than ten years of fighting, and the combat effectiveness of the entire Earth Federation army increased sharply.

However, as the war subsided and the recruits' anomalies were discovered, the top federal legislators who passed the secret bill were all arrested for crimes against humanity, and most of them were imprisoned until they died, while the remaining technical legislators were added to some research subjects, including the cyborg warrior project.

Obviously, these mecha sergeants in front of them have all undergone emotion-cutting surgery, and they no longer have negative emotions such as fear and panic, and some only have the will to fight.

The advantage of this is obvious, it allows these soldiers to continue to fight until they die, even if the Word of the Mother of Filth on the mecha shell on their bodies is damaged and their protective effect is lost, and they will not have any fear when facing those monsters that have escaped from the abyss.

Because of the singularity of emotions, the spirit will always be in a state of excitement, and it is difficult for ordinary people to maintain a healthy body in this state, and such soldiers need to inject additional nutrients every day to prevent their bodies from collapsing.

But even so, the bodies of these reformed warriors will be subject to various extreme wear and tear, so that their lifespan is very small, and few reformed warriors can exceed the age of forty.

And it is obviously impossible for these mecha sergeants in front of them to have the specially formulated nutrients of the Earth Federation, but the bodies of these mecha sergeants have not appeared in any abnormal condition, so it means that while the emotions of these mecha sergeants have been transformed, their bodies may have also undergone some extraordinary transformations.
