You must know that since the Anti-Japanese War, the Japanese have liked to engage in some biological and chemical weapons and the like, and they have also wanted to use them on a large scale on the battlefield several times.

At that time, Japan's biological and chemical weapons technology was already very mature, and it was considered the top in the world at that time.

Now that so many years have passed, they have certainly not given up the research and development of biological and chemical weapons, and the current technology is bound to be more perfect!

Therefore, it is not without reason that Chen Tang associated this underground fortification with the underground base found in the U country.

This underground fortification is very large, although it is not as big as the underground base in U country, but for Japan, a country that often has earthquakes, it is rare to dare to build such a large fortification underground!

You don't have to think about it to know that this underground ...... Surely they are doing something unseemly!

Biological and chemical weapons are banned all over the world! But it is useless to ban, some countries continue to develop it!

Chen Tang walked lightly forward, avoiding the Japanese who were working.

After sneaking for about 700 meters, Chen Tang stopped, he looked ahead a few times, and then continued to sneak.

Two hours later.

In these two hours, Chen Tang learned about this underground fortification, although it took a bit of time, but there was no way, after all, there were people in this underground fortification, which was different from the underground base of country U.

You can run around in the underground base of country U, but you have to avoid people here!

In the past two hours, Chen Tang only stood in various angles and observed the underground fortifications, and he couldn't go over many places that were being studied.

There are no cameras in this underground fortification, probably because the builders think that if there are cameras, there will be video recordings, which is not safe for them! In case it is exposed in the future, there is a video, which is equivalent to having evidence, so it is not installed!

Chen Tang had already discovered this, so he sneaked unscrupulously.

After two hours of observation, Chen Tang roughly knew how many people were in this underground fortification, and through their conversations, Chen Tang also knew what they were doing.

There are more than 3,000 people in this underground fortification, and this is still at night, how many people are during the day...... Chen Tang didn't know, he felt that he would stay here for a day during the day to explore the situation.

In front, seven or eight Japanese in white coats stared at the mice in front of them, these mice were of different sizes, the big ones were the size of ordinary two guinea pigs, and the small ones were much smaller than ordinary guinea pigs.

But without exception, they all died.

"Failed again, I guess Mr. Fujii is going to get angry again today." A Japanese man in a white lab coat sighs.

Chen Tang looked at the scene in front of him, and he saw the eyes of the mouse, which were red! Although the volume is not as large as the rat in the underground base of country U, it is also much larger than the ordinary one.

Chen Tang can be sure that they are conducting research on biochemical genetic weapons, and they definitely have a connection with the underground base of country U!

Also, about this Mr. Fujii, this is the name that Chen Tang hears the most today.

This Fujii is definitely the high-level person in charge of this underground fortification, and even one of the researchers of this biochemical genetic weapon!

Chen Tang's dark eyes narrowed, and he had a plan in his heart.

I have to find this Mr. Fujii myself, and as long as I find him, I can understand the situation and ask some questions! The worst is that I can figure out some of the conditions.

Thinking of this, Chen Tang continued to hide, listening to the conversation of the Japanese.

"Quick, go and send the things to Mr. Fujii, Mr. Fujii said that it was almost successful!" A Japanese man in a white lab coat shouted anxiously.

As the words fell, a dozen Japanese in military uniforms pushed a cart of things and ran forward.

Chen Tang clenched his fists slightly, he knew that he had to follow.

But his current American face is really difficult to make here.

So, Chen Tang moved.

With lightning speed, he sneaked up behind a Japanese man in a white lab coat, then quickly broke his neck and dragged his body behind cover.

Immediately afterwards, Chen Tang took off his clothes and changed clothes with the Japanese, and after changing his clothes, Chen Tang took off the human PI mask, revealing his original appearance.

He is Chinese, and the appearance of the Chinese is not much different from the appearance of the Japanese.

Put on a white coat, there are so many people here, and there are really few people who pay special attention to Chen Tang.

Chen Tang covered up the body of the Japanese for a moment, then strode out and ran in the direction where the dozen or so Japanese in military uniforms had left.

Along the way, many Japanese people glanced at Chen Tang a few times, but then continued to work without thinking much about it.

After running for about 600 meters, Chen Tang stopped.

In front of it, there is a research room.

The laboratory was large, and there were dozens of Japanese in white coats standing inside.

The dozen or so Japanese in military uniforms had already delivered the 'things' to the research room.

"Hahaha......" A middle-aged Japanese man with a height of 1.7 meters, a thin physique, wearing glasses and a beard suddenly laughed.

"Mr. Fujii, ...... you" dozens of Japanese in white coats frowned in unison.

His name is Fujii Harano, and he is the person in charge of the night shift in this underground fortification! There is also a person in charge of the day shift, but it is not known who it is at this time.

"Haha, I finally get it! I finally got it! Fujii Harano laughed and continued to shout, "Understood, completely understood!" After 15,313 defeats, I finally 'conquered' it! ”

"Mr. Fujii, is it ...... It worked? A Japanese man in a white lab coat asked delightfully.

"Yes!" Fujii Harano nodded, his fierce and happy gaze swept over the more than twenty Japanese in white coats, and continued: "You all let me out, don't let anyone get close to this research room within 100 meters!" I'm going to make it, and the credit for this is my own! I'm going to research it out and report back to Immortal! ”

"Yes!" As the words fell, more than 20 Japanese in white coats and those in military uniforms left the laboratory quickly.

Chen Tang, on the other hand, quickly hid nearby when he heard Fujii Hara's words.

Hades-sama?

The sudden appearance of the Hades in Fujii Harano's mouth made Chen Tang's brows furrow.

And yes, it worked!

Is it the biogenetic weapon that succeeds?

Chen Tang's pitch-black eyes narrowed, and his eyes flashed with determination.

He has already decided, this Fujii Field, must die!

I have to kill this guy today! Otherwise, the success of biochemical and genetic weapons will directly threaten China's side! After all, Japan has been watching China since ancient times!

This dog can't change its problem of eating SHI!
