"Unit 731, also known as Black Sun at the time, was one of the greatest sins committed in the Japanese invasion war. Li Yu silently recited the Heart Sutra to calm his mood and said: "Use living people to do some experiments that have lost their conscience, and observe the reaction of germs and viruses to invade the human body... At that time, we simply captured the civilian population of the country to do this unconscionable so-called experiment, to be honest, some experiments were really just abuse for the sake of abuse, just for fun, for example, in our north, they threw people into snowdrifts to freeze their hands and feet, and then beat the test reaction, this kind of experiment is meaningless and disgusting from any point of view..."

Li Yu was a little sick to his stomach when he said it, when he was a child, the teacher once showed a documentary filmed, which was called Black Sun.

Li Yu still clearly remembers that after watching the documentary, 8 percent of the primary school students in the class lasted for half a semester - the remaining 2 percent lasted for a semester, and Li Yu was in those two percent...

"According to the observation of this system, the two countries are quite friendly now?"

"Friendship or unfriendliness aside, it's peacetime, and a lot of things can't be seen. Li Yu paused and said: "Looking forward to the future, keep in mind the national shame, some things happen when they happen, and time cannot be erased..."

This is the laboratory of Unit 731, and Li Yu also knows what the little beggar sees.

What I saw was the malice and madness that remained here, densely packed like a worm that devoured everything, Unit 731's frenzied experiments, and even imprinted this evil on this land, even if time passed, there was no way to erase it...

Gently touching the remnants of the malice on the ground, Li Yu silently recited the scriptures beyond the people who suffered here.

"Their souls have long been reincarnated, and it's useless to transcend them now. The system said.

"I know. After Li Yu finished reciting the scriptures, he shook his head and said, "It's just asking for peace of mind..."

Just as Li Yu continued to move forward, he felt the fluctuation of the soul in the air.

And the spirits hovering here?

Open your fiery eyes, and there is indeed a remnant soul wandering here.

This remnant soul was wearing a white coat, a small round glasses, a mustache of Japanese standards, and his name tag on his chest, which was written in Japanese, and Li Yu did not know.

"Japanese?"

The Japanese people in front of him were muttering, their expressions sometimes crying, sometimes laughing, sometimes crazy.

"It worked... It worked... It worked... Failed... Failed... Failed..."

"Chinese and Japanese are mixed? What succeeded? What failed?" Li Yu frowned, intending to step forward and ask this wandering spirit.

But the geist seemed to be frightened by something, and fled away.

"Ding, an old wandering spirit, can gain a lot of yin virtue and merit points by spending more than his past life. ”

"Really...?"

"Really. ”

"Hmm... However, I refuse. Li Yutou didn't look back.

Just kidding, beyond these people, Li Yu feels that he doesn't have a brain, let Ya's wandering soul fend for itself here.

But at the same time, Li Yu also knew what kind of experiment they were doing to make the Japanese researcher crazy.

"Is it that the conscience has found out, and I feel that my experiment is too brutal and too self-reproachful to become like this?" Li Yu shook his head after thinking for a moment: "Impossible, they can't have mercy on the Chinese people, when they entered this laboratory, they had already abandoned their conscience..."

Li Yu thought of what his teacher said, the reason why they call Huaxia people logs is to weaken their compassion for Huaxia people.

They have the most basic compassion for small animals, but they don't have the matter of experimenting with Huaxia people, because... In their opinion, the Chinese people cannot even be counted as lives.

"Here, it's not an experiment on the Chinese... In other words, it was not just an experiment on the Chinese people, but another experiment was the reason why he was so crazy. ”

"His symptoms were so obvious that his madness was at its peak, so much so that he was surrounded by madness and confused after he died. The system paused and said, "He saw something that his mind couldn't understand." ”

......

More and more messy shredded paper and untaken materials, even... And white bones.

Wearing a white coat, the white bones lay quietly.

Some of the bones sat on chairs, some collapsed on the ground.

Some even have iron cups next to their hands, so they can be seen preparing to drink water.

"It seems that their lives were taken away in an instant, and even they died on the spot before they could react..."Li Yu squinted his eyes slightly.

"Maybe some virus germ is leaking?... No way, viruses and germs don't care about breath blocking. ”

From the state of the system prompt at the beginning of the task, Li Yu knew that he might be facing some kind of creature or some kind of monster.

But as we got closer, the style of the laboratory suddenly became wrong, surrounded by porcelain and pottery, bronze and ironware, and all kinds of jewelry and artifacts that were worth a lot of money at first glance.

"How did it become an archaeological laboratory in an instant..."

Li Yu looked strange.

At the end of this strange archaeological gallery is a decaying mahogany coffin, and next to the mahogany coffin is a coffin that looks noticeably newer.

Two coffins, displayed side by side.

Li Yu cautiously approached the relatively new coffin.

Inside the coffin was a white skeleton in a green military uniform, lying quietly.

Looking at this military uniform, Li Yu was in awe.

"I have seen it in the exhibition hall before, this is the military uniform of the former Red Army ..."

Li Yu wanted to be angry, obviously this white bone in a military uniform was also an experiment in this evil laboratory.

And in the mahogany coffin that smelled of decay, there was also a corpse.

Wearing a majestic iron armor, he lay quietly.

Looking at the iron-clad corpse in the mahogany coffin, Li Yu almost exclaimed.

"This..."

It's a corpse.

Corpse...

It's not completely rotten!

And it seems to have black fluff on its body.

At least compared to the white bones next to it, this iron-armored corpse looked like it hadn't been dead for long...

"This corpse..."

Li Yu squinted his eyes, wanting to take a closer look.

As soon as he got closer, Li Yu hurriedly retreated to the side.

Corpse.

It's moving, this corpse in iron armor is moving...

Those who look dead can't die anymore.

"He's not dead... No, he's dead..."Li Yu's brows jumped: "This is a zombie... It is a danger that the system prompts. ”

At this time, the iron-armored zombie in the mahogany coffin suddenly trembled.

His eyes suddenly opened, and his whole body popped up.

There is no flesh on his cheeks, but Li Yu can see that if there is meat, his expression should be very crazy...

"Blood... Meat... Blood... Hungry..."

The ironclad zombie stood up and leaned in the direction of Li Yu.
