Charlotte Four, left.

Under the persuasion of Yang Xiaokai, towards the junction of the Eastern Xia Empire and the Frost Principality.

They continue to stay here and do not do much.

But you can't just let them go back.

Not to mention that going back directly is not beneficial to them, and more importantly, since that organization has done it, then it can definitely be said that there are killing machines all over the way back, to be honest, if they are really allowed to go back, Yang Xiaokai is a little uneasy.

Therefore, his recommendation is either to hide or to challenge, rather than return to the Empire.

The sea monster training ground, it is undoubtedly a good place, and after this side is done, Yang Xiaokai will probably turn to that side.

From that position, he entered Eastern Xia in the east, crossed the three provinces, and finally turned to the Northern Emperor, completely avoiding the Yama Rainforest.

Even if it is said that the current Dongxia Union is the same, it is undoubtedly much better than the Yama Rainforest, and the other party is too unscrupulous here.

After sending the four of them out of the city, until they stepped out of the range of their divine sense, Yang Xiaokai returned to the Great Bear Pass.

Taking a breath, without any hesitation, Yang Xiaokai quickly escaped into the underground and headed towards the big underground hole in the center.

That's just it.

However, after more than an hour, Yang Xiaokai paused slightly before coming to the big hollow again, and after making some preparations, he sneaked in directly.

Big hollow.

It's a huge space.

From the distance, it is about one-third the size of Daxiong Pass, there are countless buildings inside, and there are countless cable ground wires to the naked eye, obviously different from the outside, the level of technology here is very high.

Not to mention the rest, in terms of energy supply, it is undoubtedly the world's top, that is to say, it can be compared with the three major empires.

With a slight movement of thoughts, Yang Xiaokai quickly lurked towards the room closest to him.

One, one, one.

Yang Xiaokai was not in a hurry, it was just a constant inspection of room by room.

With such an energy supply, everything that the organization has built underground here is absolutely amazing, and the fields involved are beyond imagination.

Mechanic...?

After walking through most of the outer rooms, Yang Xiaokai frowned slightly, and finally understood the origin of the bomb in the rainforest, which should obviously come from here.

Judging by the weapons they saw, that organization was indeed very powerful, and there was no doubt that they were ahead of the world in terms of weapons.

It's a shame that there is no uranium ore in this world, and you can't make anything like a nuclear bomb, otherwise the weapons here would be really scary.

Of course, even so, the weapons produced by that organization can definitely be said to be dazzling, from small weapons to weapons of mass destruction.

However, it is clear that these weapons are okay against ordinary fighters, but it is difficult to play an effective role in the face of world-class powerhouses.

For example, Xia note, even if she is not a world-class powerhouse, under the elementalization, it is basically difficult for these weapons to hurt her, unless that organization adds the spirit extinguishing stone to the weapon, which is the core material for making the battle magic suit.

Obviously, this kind of thing is basically impossible, even if there is a considerable number of spirit extinguishing stones under the Big Bear Pass, but the number is at most to make one, or even about half a battle costume, well, here is talking about the national level, and the provincial level can make a little more.

Directly on thermal weapons, the value is undoubtedly too low.

After all, although that weapon can kill Charlotte, it also says that Charlotte who is not wearing a battle suit will undoubtedly reduce her damage infinitely if she wears a battle suit made of the same substance.

After quickly looking at the peripheral thermal weapon production and confirming that there was no huge threat to the weapons here, Yang Xiaokai began to go deeper.

Well?

Walking through the thermal weapon processing room, Yang Xiaokai couldn't help but pause, and his eyes looked straight at the things like cultivation troughs placed in the first large room of more than a thousand square meters that he stepped into.

This is....

Looking at the monster contained in the cultivation tank, which has lost its human form and has become extremely hideous, extremely terrifying.

Something that once hunted down himself....

Sure enough, although brainless, for this organization that seems to be crazy, has this kind of thing with obvious drawbacks begun to be mass-produced???

Or is it a weapon, but it has jumped from a machine to a biological weapon?

Looking at the busy staff around him, Yang Xiaokai's eyes showed a look of surprise for the first time.

As a terrorist organization, to be honest, the technological development here is really a bit beyond imagination, not to mention the mechanical aspect, in the absence of uranium mines, how to develop is to that point, if the empire wants to, it will be able to catch up in about a year.

But it's different here.

In terms of biological weapons, this organization is at least 100 years ahead of the world.

The gap of a century is really terrifying, after all, under the era of warriors, the development of both biological and biochemical sciences is extremely slow, that is to say, reaching this level is completely developed by this organization itself, and it has also formed a scale.

Even if it is a hostile position, I still have to admit that it is awesome.

After feeling it a little and making sure that the other places around him were basically the same as here, Yang Xiaokai did not continue to waste the world, and went directly deeper.

Unlike weapons, biological weapons, and still biological weapons with drawbacks, there is no idea of peeping at all.

If he thinks that if he comes up with a design drawing for a purely human enhancement agent, it will be able to completely surpass this place in about ten years.

Yes?

You said that when Ye Huang was not in good health at the beginning, why didn't he think of making a booster? Please, you can't use Dao techniques, purely rely on scientific practice, not to mention how long it will take to succeed, even if it is successful, what does Yang Xiaokai have to use to explain the knowledge field involved in the booster?

Spend a decade or two researching? No kidding.

Sure enough, no matter how advanced this organization is, its existence is undoubtedly disgusting.

After another distance, except for the outermost machinery, which was still normal, the further inside, the more crazy the organization's behavior undoubtedly became.

Biological weapons, biochemical weapons, people, animals, plants, all the things that can be experimented with are all placed here, one by one on the dissecting table, or in the culture tank.

Looking at the crazy experiments below, even after a lot of lives were suppressed because of a test subject's rampage just now, an even more crazy experiment began.

Obviously, for that organization, their quest is not to be accessible, but to be strong and acceptable no matter how many flaws there are.

Undoubtedly, if they continue to experiment like this, I am afraid that one day they will not need to be done by that organization, and a certain mutant in these things may have the possibility of destroying the world.

It's impossible to determine the end goal of that organization, but perhaps, perhaps, this outcome is what they want.

Taking a deep breath, Yang Xiaokai locked his gaze on the central position, the last huge building.

That's just it.

Undoubtedly, compared to the other rooms, this place is very well guarded, all entrances are sealed, and there are no windows to see inside.

If everything outside is the result of a hundred years of that organization, this should undoubtedly be the place where their efforts gather.

After waiting for a while, while one person entered it, Yang Xiaokai also dodged and walked in.

The internal scene caught his eye for a moment, and Yang Xiaokai changed color.

This...???
