A few minutes later, there was silence in the A-3 lab, and several researchers had been completely drained of their brains and collapsed to the ground.

From then on, they no longer had to worry about the shortage of materials for live experiments.

The white light flashed, and Zuo Chen had already put the corpses of these researchers into the storage space.

If the body is found, it is estimated that the entire base will be on alert, and if these people are just missing, it will take a long time to investigate, and the base's response will naturally not be so sensitive.

Then he took out two vests and two hats again, threw them to Zhao Ritian, and said: "This is the shielding suit given by Chenlong, which can block the detection of the base's artificial intelligence, stealth in front of electronic devices, and put on a meow." ”

Zhao Ritian grabbed his waistcoat and hat, and looked puzzled: "Brother Cat, why is it green?" ”

The vest and hat were all bright green, so green that the dog panicked.

"I don't know," the orange cat rolled her eyes, "put on meow, let's hurry." ”

A cat and a dog put on their vests and hats, and looked at each other a little awkwardly.

Then Zuo Chen took out a cloak from the storage space, but it was the optical camouflage he got from the Shennu team when he was in the ruins of Weicheng before.

There is even a bit of urine smell on this optical camouflage, and it can't be washed off, but now in order not to be discovered, I have to make do with it.

"Wang, Brother Cat, do you still have this? I really miss the days of the ruins of Weicheng, and the abyss of Weizhi. Zhao Ritian said excitedly.

"Don't crow's meow!" Zuo Chen's eyes widened, and he shook the optical camouflage cloak, covering himself and Zhao Ritian.

Turning on the switch of the optical camouflage, a cat and a dog disappear in place, and if you look closely, you can still find some outlines, like flowing water.

It's just that this is enough, their footsteps are extremely soft, and they are walking on the ground against the corner of the wall, and they can't be noticed without careful observation.

Walking out of the laboratory into the hallway, I looked around, and saw that there were only a few people walking in the hallway, and no one noticed them.

"Brother Cat, where are we going next?" Zhao Ritian asked in a low voice.

"Keep learning about biology." Zuo Chen walked in front and whispered: "Knowledge is priceless, such a good learning opportunity can't be wasted." ”

Through the "study" of Director Liu just now, he has found that the research on zombie viruses at the Shenlin Base of Jicheng Fortress has reached an extremely high level, especially in terms of biological activity enhancement, genetically modified experiments, and human debugging, which is far beyond the knowledge he originally "learned".

There is even a lot of knowledge about the evolutionary mutations and energy transformations of the Abyssals.

If you can "learn" as much biochemistry as possible, it may also be helpful in the treatment of Guoguo's condition.

Moreover, the more high-level the researcher, the deeper the understanding of the entire Divine Presence Base, and if you want to go deep into the twenty underground floors to find those energy fragments, it is essential to have a deep understanding of the base.

At this time, Zuo Chen was already familiar with most of the situation in these laboratories in the base, and walked forward with Zhao Ritian with a familiar car, and after a while, he had already come to another A-laboratory.

In this laboratory, human experiments were underway at this time, and one test subject was injected with an excessive amount of virus mixture, and blood seeped out of the pores of his body, and he had become a bloody person, and he couldn't see it alive.

The doorbell rang and a researcher opened the door, only to find it empty, and then felt a gust of wind pass between his legs, and he looked down, but saw nothing.

The researcher shook his head, thinking it was his own hallucination, and casually closed the heavy metal door that was soundproof and radiation-proof.

Then, a series of screams echoed through A-Lab, and the researchers, who had accumulated a large amount of experimental data, quickly turned into zombies, and then were sucked dry by the terrifying orange cat.

Then, when everything calmed down, the door to the lab opened again, then closed on its own.

Unlike before, the lab was empty......

After sweeping three laboratories in a row on this floor, Zuo Chen and Zhao Ritian came to the elevator and walked in.

Zhao Ritian's dog face was full of excitement and said, "Brother Cat, you are too powerful!" When I used to watch those alien movies, I was very envious of those monsters who could kill all sides in the experimental base, and today we can have a good time......"

Zuo Chen smiled, waited until the elevator door closed, took out an eyeball and a finger from the storage space, and placed the eyeball and finger in the place of identification.

Immediately, an electronic synthesized voice came out: "Identity confirmed, Mr. Kong Xiangbai, the core director of the department, authority S-level, please select the floor." ”

Zuo Chen pressed the minus 5 floor with his claws, and the elevator immediately continued to go down.

Leaving Kong Xiangbai's eyes and fingers before is really correct, this thing is also an S-level divine slave, and the authority within the Shenlin base is basically top-level.

Speaking of which, his combat power is definitely not weak, but it is a pity that he was overshadowed by Zuo Chen, locked in an energy cage, and in the end, he was completely killed alive as a live target.

The elevator went all the way down, and a cat and a dog had already arrived on another floor for live experiments.

The laboratories here are all S-level, surpassing the A-level laboratories just now, and the resources equipped are also the top-notch, including the researchers who can be used to "learn".

At this time, Zuo Chen was looking forward to it, hoping to meet the Song Tianqiao from the Yancheng Ruins Biological Research Institute here!

However, according to the information he got before, Song Tianqiao's position within the Divine Presence Organization is not low, and he no longer even participates in this kind of experiment in person, so it's really hard to say if he can meet him here.

A cat and a dog did the same, first found the S-3 laboratory, did not knock on the door at all, and directly broke in while no one used Kong Xiangbai's permission.

In the laboratory on this level, all the test objects are all humans, and many of them are power generation monkeys secretly captured from the outer area of the Jecheng Fortress, or deceived in the name of recruiting employees.

Each laboratory is large, and in this No. 3 laboratory alone, there are as many as ten test subjects who are locked up in the test chamber.

As the heavy metal door closed again, several researchers who were conducting the test suddenly heard a sound of squeezing, and then saw an orange cat and a teddy standing in front of them.

"Where are the cats and dogs?" A Shennu researcher said curiously.

"Hello everyone, I'm here to learn from you." The orange cat waved its paws, and the cat had a tiger smile on its face.

"Learning? What to learn...... The cat ......" The humans were about to be shocked when the teddy leapt in front of him, raising his blood-stained paws and giving each of them a look.

Although it only scratches the skin, it is fast enough to spread quickly!

At this point, whether they are wailing or begging for mercy, it is no longer useful!

When the first zombie appeared, the orange cat's tail immediately stabbed it!

A few minutes later, Zuo Chen had finished studying, and Zhao Ritian quickly cleaned the laboratory, put all the corpses into the storage space, and left here again with optical camouflage.

After a while, the S-class laboratories on this floor had all been "studied", and the cat and dog walked into the elevator again with satisfaction.

Although they had been trying to be cautious before, they were still discovered by a divine slave, but fortunately, they went up to solve it before the other party called, which can be regarded as a danger.

Moreover, due to the need for confidentiality, there is no real-time monitoring equipment inside these S-level laboratories, which can be regarded as a great help to Zuo Chen.

After dozens of "studies", Zuo Chen has a deeper understanding of the research results of the current Shenlin Organization, and he can already be called an expert in biological viruses.

Even some of the energy release phenomena in Guoguo's sleepiness can be answered now.

These studies can be said to be very fruitful, even if he can't find the recipe for the path of evolution, with the knowledge he has now, he should be able to help Guoguo solve some problems.

However, the more he "learned" about biology and energetics, the more he felt that Guoguo's current situation did not seem to be so serious.

The little girl's painful appearance before didn't seem to be physical pain, but ...... Mental anguish?

Is it a nightmare?

I don't know which bastard made my daughter so unhappy......

Just as I was thinking, the elevator door opened, and the twenty basement floors arrived.

This is where the Divine Presence Base collects energy fragments!

According to the information provided by Chen Long and Zhang Hang, there are hundreds of energy fragments here!

……

At the same time, ten floors underground, the A-2 laboratory.

A Shennu researcher came to the door of the A-2 lab with a pile of materials in his hand and rang the doorbell.

He is also a member of this laboratory, went to the analysis room to get some experimental data, and just came back.

But I didn't expect to press it for a while, and there was no movement in it.

The mustachioed researcher frowned and was about to report to his superiors when a man in a guard uniform suddenly appeared behind him and asked, "What's wrong?" ”

"Hello, there has been no movement in the laboratory, I suspect ......" Mustache hurriedly said to the other party.

It's just that before he finished his sentence, the guard suddenly stepped forward and leaned in, and the syringe in his hand instantly pierced the mustache's neck, making his eyes blur and fall softly.

The guard grabbed the mustache, turned his head to look around, saw that no one was there, and immediately dragged the mustache into a nearby utility room.

Then he whispered through the walkie-talkie on his collar: "The boss has successfully infiltrated, the boss has successfully infiltrated, and all units try their best to cooperate with the boss to cover their identities and avoid exposing their identities at the same time......"

Speaking of this, he seemed to think of something again, paused, and continued: "...... Rainbow Cat Protection, ver. ”
