At this time, in the place where these little beggars were held, there were still residues of food and excrement on the ground, and the stench was mixed with the damp smell of cheap food, which was worse and disgusting than the one coming down from the bridge hole, and the part-time job was a breeding ground for germs, Ouyang Qi and Gu Tai were okay, Qiu Yanlan couldn't help but cover her nose with her hands, and she was not used to the smell of corpses here.

"Master, are there any other questions?" asked Gu Taisan cautiously.

Li Yu stood in the room where these little beggars were being held, and muttered, "When you check here... Didn't find anything strange. ”

"The place itself is strange enough. Gu Taisan complained.

I wanted to say no, but Ouyang Qi said.

"There's... In this amputation clinic, a lot of the equipment is almost the product of the last century, and so are the medicines..."

Ouyang Qi casually took down a pot of medicine jars, and after blowing off the dust, it was full of Japanese.

"This is an expired painkiller, produced in the last century..."

Li Yu found that there were many similar drugs on this shelf, all written in Japanese and covered with dust.

"Their dens are always moving like crazy, which means that the medical equipment was already here before they moved here. Li Yu frowned.

"No, maybe earlier, before this factory was built, there might have been this basement. Ouyang Qi said

Before the factory was built, there was a basement here...

Qiu Yanlan was puzzled: "Before it was built, what was it like before it was built, medical laboratory?"

"It seems to be just an abandoned wasteland, built here on flat ground..."Gu Taisan muttered: "Actually, I also think it's strange, how can there be a basement here... There are so many containment chambers and stuff in the basement. ”

Qiu Yanlan said suddenly.

"In other words, before that, this basement was used for experimental containment? What is contained? What is it for experimentation?"

"Containment experiments, and the timing is probably the end of the last century. ”

The basement is huge, and apparently the 'beggars' have not used it all, and there are many rooms that are even locked.

Maybe it's not that the beggars don't want to explore, but this big iron lock is too difficult to get through...

Looking at the big iron gate in front of him, Li Yu turned around and said, "Let's go on your own on the next road, there may be some dangers below." ”

Although the fiery eyes can't see anything now, the child with spiritual vision said before that there are dense little insects.

Gu Taisan hesitated for a moment and stopped: "Anyway, our people are searching above, and they won't disturb you, so relax." ”

Under the horrified gaze of Qiu Yanlan and Ouyang Qi, Li Yu directly broke off the big lock...

Gu Taisan is very calm.

"I've seen more of the master's abilities... If human beings have limits, then masters are beyond the limits of human beings. ”

"I'm going in first..."

Li Yu walked slowly towards the abyss in front of him...

........

It's very well sealed and there's no dust around it.

But on the other hand, the air here is also very thin, and Li Yu feels as if he is standing on the clouds, and he can't breathe at all.

"It's a shame that I didn't let them in, otherwise, I would have been able to hold back and have an accident..."

The slightly eerie corridor is a bit long.

In addition to being very gloomy, there are also some cold malice entanglement here, which makes Li Yu very uncomfortable.

"Sure enough, the malice and coldness on the pen fairy's piece of paper came from here, not entirely from those people from the beggar gang, those people can't exude this pure malice..."Li Yu groaned, feeling the solemn pressure in the air, very viscous, making people feel disgusting from the heart.

Here, Li Yu is given a bottomless feeling, as depressing as an abyss...

"Ding—"

"Congratulations to the host for triggering the hidden task. ”

The prompt sound of the system suddenly sounded, and Li Yu looked surprised.

There is actually a hidden mission that is triggered?

"What is the source of malice in the cold basement?"

"Quest Tip: Floating malice is identified as dangerous, please be prepared to use the charm at any time. ”

"Mission Support Status: Requires 500 Merit Points, do you want to pay it?"

"I'm going to go, and now the mission support status has become to be recharged?" Li Yu was stunned, when did the system become so cheating.

"To pay or not to pay?"

"Payment, of course payment, 500 merits for a small life is still worth it. Li Yu muttered, the system said that there is a certain danger, that is, it is really dangerous: "A little nervous, what is dangerous in this basement..."

"Mission Support Status: Breath Blocked. ”

"Breath Block: You are now acting as a dead person, and even creatures with six senses will not be able to detect you. ”

Li Yu could feel that he was covered by a thin film.

The breath and temperature were all gone, and even the subtle spiritual power that was escaping all the time was completely sealed.

As described by the system, the current state of manifestation is already a dead person...

"Need to shield my breath and temperature to explore... The danger here is heat-sensitive, like snakes?"

Li Yu's expression was also serious, and he cheered up.

Along the way, there were a lot of bottles and cans that fell messily on the ground, all of which were medicines with Japanese handwriting written on them.

When he approached, Li Yu could feel a tingling pain in his body.

It was the body that was sending an instinctive warning not to approach Li Yu.

"What the hell is up ahead..."

When I opened the door in front of me, the floor was still full of bottles and cans, but there was something different.

Seeing this thing in front of him, Li Yu's blood immediately surged.

It was some test tube jars, with white paper pasted on them, and the words were written in English.

Plague.

Malaria.

There are also rows of words with the names of viruses and germs...

The most important thing is that there is a broken old paper in the middle, which is also full of Japanese, Li Yu is not very familiar with Japanese, but the teacher has taught some knowledge when he was a student, so that Li Yu knows some Japanese meanings, and he is extremely familiar and sensitive.

Where it was not burned, the Japanese word "log" appeared.

"Warning, the host's mood and body temperature are unstable, which will affect the occlusion effect of breath blocking. The system paused and said, "Host, do you know what this place is?"

"Of course I know... Japan has committed many heinous crimes in China, one of which is the bacteriological warfare experiment. Li Yu forcibly calmed down some of his anger and said: "This is the former laboratory site of the Japanese Unit 731, the place where the bacteriological warfare research experiment is located." ”
