"If all this happened before the cataclysm, then the people who opened this lab are certainly not good people, they are conducting human experiments here, maybe their experiments led to the cataclysm." Zhang Shengli speculated.

"yes, it doesn't look like a normal place at all." Wang Decheng nodded.

"Haven't you local survivors heard of these horrific human experiments before? For example, who suddenly disappeared or something? Someone will report the crime, right? Zhang Shengli looked back at Li Miao.

"I haven't heard of it." Li Miao shook her head.

"Didn't you listen to Zhou Jingjing? They bought corpses for experiments, perhaps while studying how to bring them back to life, and the result was that these living dead came out. Wang Decheng replied to Zhang Shengli a few words.

"Maybe." Zhang Shengli nodded.

The group continued down the hallway towards the depths of the lab, arriving at a large room at the end. Everything in the large room was even more shocking, and there were huge glass cabinets on the walls of the room, which seemed to hold something.

Some look like human embryos, some look like human organs, and some grow into humanoid shapes, and there is even a humanoid creature, Zhang Shengli suddenly opened his eyes and startled him when he took a flashlight into it.

"What the hell are they studying?" Li Miao asked Zhang Shengli in fear.

"I don't know what they're working on, but they certainly haven't done anything good." Zhang Shengli frowned.

At the end of the large room, after opening the door, there is a staircase behind it, and the depth of the ground is far beyond everyone's imagination. The next few floors are free of those disgusting animal or human tests. There are some very delicate and even very large instruments all over the place. It's like I'm doing research on electromechanics.

One of the floors is about six meters high, and it may have reached the bottom of the river, and the area looks much larger than the previous floors, and the laboratory is like an upside-down skyscraper, and the part that emerges from the water is only the tip of the iceberg.

"This is where plasma nanobots are developed!" After studying some instruments and equipment, Galaxy looked a little excited.

"Plasma nanobots? Is it the kind of nanobot in your body that gives you energy? Liu Qian replied to the Milky Way.

"yes, let them be careful not to break the equipment, I should be able to find something that will work for me." Galaxy nodded.

Liu Qian immediately issued an order to go down. Let everyone not act rashly on this level, and when encountering zombies, the attack action must also be very restrained, and nothing in the laboratory on these floors can be destroyed.

"Found it!" After descending two more floors, Galaxy found several metal tubes about ten centimeters long in the alloy cabinet next to a large machine, which looked like syringes when opened, but the shell was not glass, but alloy.

"What is this?" Liu Qian saw Yinhe's excited expression and knew that she must have found something useful.

"It is a new type of plasma nanorobot that is being tested and ready to be mass-manufactured in the future, and the future application of plasma nanorobots should be very wide. It has become the standard configuration in many related industries. This huge machine can simulate millions of volts or more in an artificial environment, and then inject the resulting plasma into these nanobots. Sealed in these injection devices. According to the information downloaded from the database, Yinhe explained to Liu Qian in detail.

"You mean, these syringes contain nanobots that are already filled with plasma energy?" Liu Qian also looked very happy when he heard this, which seemed to be a temporary solution to the power supply problem of the galaxy.

"Yes, only ten tubes have been produced so far, and each tube can provide me with about two days of energy consumption, and these ten tubes can give me at least twenty days without worrying about the lack of energy." Galaxy said as she opened one of the injection devices, revealing the needle inside, and injecting it into her wrist.

"This needle is very powerful! Can you prick your skin? Liu Qian glanced at the place where the needle had been pierced.

"It's not that the needle is bad, it's that I have a nanobot injection hole on my wrist." Yinhe explained to Liu Qian.

"What about these injected nanobots? Is it really full of plasma energy? Liu Qian asked Yinhe again with some unease.

"Yes, they're all full of plasma energy, and they're a huge addition to the number of nanobots in my body. You must know that these nanobots have a certain lifespan, and if they can't be replenished in time, their number will decrease as my body consumes. Yinhe replied to Liu Gan.

"So? After that, we will have to often find some secret laboratories of the Three Domains Company, and strive to find more nanobots for you, and even more and more advanced nanobots. Liu Qian said a few words to Yinhe.

"Okay, thank you, brother." Yinhe smiled at Liu Gan, I don't know if she was so happy because she found the plasma nanobot, or because she became more intimate with Liu Gan, anyway, Liu Qian liked her more now.

After packing several other nanobot injection devices into his backpack, Galaxy searched around, but found no more. It seems that the plasma nanobots here are also only in trial production and have not entered the mass production stage.

After going down two more flights of stairs, the underworld became eerie, or it was possible that it was because they had been down for too long, and the temperature of the underworld was very low, which caused chills on everyone's bodies, so they felt cold and gloomy.

The air here is also very bad, giving people a very dirty feeling, and it is not surprising that the ventilation system of the underground world should have stopped working a long time ago, and now this deep air can still breathe.

Liu Qian, Zhang Shengli, and Wang Decheng, who had advanced to level 5, were barely able to adapt to this kind of air, and the other players and local survivors were a little unable to hold on.

Liu Qian didn't let them go down any longer, let them stay in the layer where the air was still enough for them to breathe, and then continued to explore the underworld below with only Yinhe, Zhang Shengli and Wang Decheng.

There are no emergency lights here, so they can only be illuminated by flashlights, and when you turn on the flashlights and shine them on both sides, you can find that this place is more like a prison, separated by an iron fence into small rooms. (To be continued......)
