Koji Oda, who had lost his troops in front of the fortress and returned again, had red eyes, he didn't know that as the top warrior of the empire, he would be humiliated by those cowards several times!

This is too embarrassing for an old-school imperial soldier like him, who values his reputation and dignity more than his life......

He now needs to kill people, vent his anger, and use violence to solve all the civilized ...... of human society.

And at this time, the best target is the group of soldiers in front of him who don't know how to enter his territory......

At this moment, Koji Oda led the remaining 30 or so Imperial warriors more than a kilometer away from Leng Zifeng's camp, these people were completely unafraid of their surroundings, and could lurk in the tropical jungle full of poisonous snakes and insects for a night without moving.

Although Koji Oda is bloodthirsty and tyrannical, he is not stupid at all, he knows that the team of Leng Zifeng in front of him is huge and well-equipped, and it is almost impossible to annihilate all of them at once with the more than thirty imperial soldiers in his hands alone, not to mention that these imperial soldiers in his hands now are the foundation for him to restore the glory of the empire in the future, and he really can't lose them easily.

And the best way to deal with this human army in front of them is to use the zombie worm, the ultimate test product that their empire has researched in this biochemical laboratory!

So this time, Koji Oda patiently led these of his men all the way to the periphery of the Leng Zi Peak camp, motionless and waiting for an opportunity......

Of course, Gu Xiaole and the others didn't know that the group of biochemical Japanese troops who had just been defeated by themselves had already gone out of the valley to fight with Ning Lei's fiancé Leng Zifeng, and all of their attention was now completely focused on Ning Lei's body, or to be precise, on the diary in her hand.

This diary was obtained by Ning Lei and Gu Xiaole yesterday from the lilac smoke in the underground laboratory who claimed to be the person who claimed to be Xiong Er Inoue, because this diary was quite thick, and they were tired and sleepy after they came back yesterday, so Ning Lei didn't look at its contents.

Just now, when Gu Xiaole and Alida were fighting fiercely with Koji Oda outside, Ning Lei was busy flipping through a few pages, she didn't know if she didn't know it, she was shocked when she saw it!

It turns out that there are still so many secrets hidden in this fortress.

The contents of the front of this diary are basically the work records of Professor Kumaji Inoue, and it can be seen between the lines that this biology professor has been involved in the construction of this fortress since the beginning of the site selection.

So he still knows a lot about the origin of this fortress.

First of all, during World War II, after the Japanese army occupied most of the Southeast Asian countries, they suddenly got an ancient manuscript from a small Southeast Asian royal family.

According to this ancient text written on parchment, on a mysterious island between the continents of Asia, Africa and Australia, there is a desert island known to the locals as the Devil's Tears.

It is said that in the valley in the center of this deserted island, there is an underground cavern that emits strange smoke all year round.

All the flora and fauna that surround this cave are completely different from those outside.

Giant insects that are several meters long are often present, and ancient ferns that should have grown very short but are now unusually tall.

The local natives believe that the cave is inhabited by terrible demons, and that the mysterious smoke emitted from time to time is the gas that the demons exhale when they breathe.

Everything living in the world will become the hands of demons when they are contaminated with this gas, including those giant insects and ferns!

As the world's top biologist at the time, Kumaji Inoue was very interested in this, of course, he definitely didn't think that there would really be any demons or anything like that on this desert island!

However, according to the description of this manuscript, it is likely that there are some strange substances on that desert island that have not yet been discovered by humans, and this discovery is likely to be another major discovery after Darwin's theory of biological natural selection!

So he immediately asked the Imperial Military Department to conduct a large-scale search of the area described in the manuscript, and after the Imperial Military Department invested a lot of manpower and material resources, the deserted island was finally discovered a year later.

The mysterious valley in the center of the desert island was found, and as described in the manuscript, it was full of ancient tall ferns and some huge insects and arthropods.

Although he lost a lot of Imperial soldiers in the process, the overjoyed Professor Kumaji Inoue continued to search in the center of the valley, and sure enough, he found the mysterious cave, the strange thing about this mysterious cave is that it will release some lilac smoke-like substances from the depths of the cave at regular intervals every day.

Once humans come into direct contact with this substance, they will immediately become irrational and extremely violent, and at the same time, the muscles and bones in the body will begin to become extremely developed and aggressive!

As soon as this important discovery was reported, it immediately attracted great interest from the Imperial Military Department!

At that time, the empire that was already fighting in the Pacific Ocean deeply felt that the number and combat effectiveness of its own country were obviously insufficient, and if Professor Inoue Kusuji's discovery could produce stronger and bloodthirstier imperial soldiers for the empire, wouldn't it be able to gain an overwhelming advantage in one fell swoop?

As a result, the Imperial Military Department at that time immediately sent Koji Oda and Kumaji Inoue to take charge of the construction of this military laboratory.

In order not to attract the attention of the Warring States, the military headquarters sent a large number of transport planes to airdrop construction materials in the valley, and used ordinary fishing boats to secretly bring in a large number of laborers and prisoners of war from the occupied countries as workers to build this secret fortress.

After two years, the laboratory was finally built, and the prisoners of war and laborers who survived the construction process were unlucky enough to become the first laboratories!

"In this case, that Kumaji Inoue is the same as Koji Oda outside, it's not a good thing, right?" Hearing this, Lin Jiao interjected suspiciously.

The little girl's words this time can't be unreasonable, after all, a scientist who can use a large number of innocent human lives to do experiments is indeed difficult for people to believe that he is a good person.

However, Alida, who was accustomed to killing on the battlefield, did not see it that way, she shook her head and said:

"An experiment is an experiment, and there is no essential difference between the two whether they are using humans or mice.

But we ourselves are willing to make it an unforgivable sin to hurt our fellow human beings!"

In this regard, Gu Xiaole did not rush to a conclusion, waved his hand to signal that the two of them did not need to discuss this first, and then let Ning Lei talk about the account in the diary.

The diary was followed by a large number of laboratory data records, which several people had never been exposed to before, and now they were a little creepy to hear this.

It turned out that after the cave was dug up, Inoue Kumji found that there was a meteorite with a strange shape at the bottom of the cave, and that strange lilac material was emitted from this meteorite!

It was also an amazing discovery, so they built a huge sealed laboratory around the meteorite.

And according to Oda Koji Daisa, as soon as the laboratory is completed, it will start using those laborers and prisoners of war to conduct human modification experiments!
