Zhou Bai originally thought that Dr. Zhuang would have any countermeasures, but he didn't expect that he would say this.

"Pray that we will be lucky and will not be discovered...we... are already the last hope of mankind." After patting Zhou Bai's shoulder, Dr. Zhuang left.

Zhou Bai looked at Dr. Zhuang's somewhat lonely figure, combined with the cat that appeared yesterday, and couldn't help but mutter in his heart: "A monster? If the body of the white cat is in the base, then Dr. Zhuang knows... or doesn't know?"

With the thought in his heart, Zhou Bai couldn't help but think: "Do you want to tell him about the cat?"

Both the white cat and the auxiliary system brought by the white cat are too suspicious, and they are even closely related to Zhou Bai's current situation, which makes Zhou Bai unable to help but doubt the other party's purpose. After all, he believes that there is no free lunch in this world.

Dr. Zhuang is even more suspicious. Whether it is the underground base, the rumors of the doomsday, or the strange demon classes, they all reveal a sense of evil nature.

‘Tell Dr. Zhuang everything? Or should I go find the cat that might be a monster myself?’

After thinking about it, Zhou Bai still made up his mind: "There are too few clues, so I'll look for it myself for the time being. At least if this auxiliary system can be used, it can be more self-protection."

At this moment, Zhou Bai felt his shoulder hit hard, and a boy nearly 1.8 meters tall walked past him with a cold face.

Elsa walked up and shouted, "Hey! Bandu, what are you doing? Don't you look at people when you walk?"

The boy known as Bandu turned his head and glared at Aisha and Zhou Bai coldly: "If you don't want to be hit, then don't block in front of me."

Looking at Bandu's departure back, Zhou Bai pulled the corner of his mouth: "Damn, this kid is very arrogant."

Elsa jumped angrily, looked at Bandu's leaving figure and shouted, "I won't say anything if I block you!"

"This is not the key to the problem..." Zhou Bai patted Aisha on the shoulder helplessly and said, "Okay, Aisha, go for dinner."

When talking about the issue of eating, Aisha's eyes immediately lit up, she immediately forgot the unhappiness in front of her, and happily followed Zhou Bai to the cafeteria.

The two of them sat down with the meal, and Zhou Bai thought about his next plan.

"I have basically visited the living areas on the second and third floors of the underground. If the cat is really at the underground base, it should be on the fourth floor or the fifth floor?"

Thinking of this, Zhou Bai asked, "Aisha, have you been to all the places in your base? Have you ever been to the fourth and fifth floors underground?"

Aisha was consuming the synthetic nutritional paste in the bowl, and seemed to have not heard what Zhou Bai said at all.

Zhou Bai asked several times, and saw that the other party still couldn't hear it, so he took the other party's bowl directly, but saw Aisha stretching her head and eating the moving bowl all the way.

"This guy..." Zhou Bai has also figured out Aisha's characteristics these days, and simply waited until the other party finished eating before asking.

Aisha: "When we helped the teacher move things, we went to the fourth floor underground. We never went to the fifth floor. No one can go to the fifth floor except the teacher."

Next, Aisha told Zhou Bai little by little what she saw on the fourth floor.

On the chair behind Zhou Bai, Alice listened silently to the conversation between the two, and a thoughtful look on her face.

A few days later, when the demon class ended, Dr. Zhuang called for a few students to help him carry things, Zhao Yao volunteered to stand up.

More than a dozen students followed Dr. Zhuang to the fourth floor underground. What appeared in front of Zhou Bai was a huge warehouse, which placed the materials needed for various bases in different categories.

As Dr. Zhuang ordered tasks one by one, the students came to different places to move the supplies up again and again.

After Zhou Bai moved two boxes of things up, when he came back to move things again, he looked around and saw that no one was paying attention to him, so he walked towards the depths of the warehouse.

"First check whether there is any on the fourth floor. If not, I can only find a way to search for the laboratory on the fifth floor underground."

Zhou Bai walked along the rows of supplies in the corridor and saw a large amount of nutritional paste, compressed biscuits, pure water, various medicines, medical devices, and common tools...

"It seems that nothing special..." Zhou Bai paused and saw a clearing space full of dilapidated devices.

"This..." Zhou Bai picked up a cylindrical thing and guessed while fiddling with it: "Is it a flashlight?"

The next moment, his eyes lit up and he grabbed a small appliance next to him: "This one looks a bit like a radio."

Zhou Bai tried to press the switch, but found that there was no response.

"Is it broken? Or is it out of power?" Zhou Bai searched around for a while, and he actually found two batteries out of an appliance.

After stuffing the battery into the radio, Zhou Bai turned on the radio again and immediately heard a rustling sound from the radio.

After adjusting the frequency several times, he didn't hear the voice. Zhou Bai suddenly reacted: "This is underground, I guess I can't receive any signal..."

Just as Zhou Bai felt disappointed, the sound of the radio in his hand suddenly froze.

"This is the Heavenly Court Rescue Team, this is the Heavenly Court Rescue Team."

“We are rescuing humanity worldwide.”

"Survivors who received the message please..."

Zhou Bai looked at the radio in his hand in shock, but the sound inside disappeared halfway through the speech. The radio made a rustling sound again. No matter how Zhou Bai debugged it, he could no longer receive the sound just now.

At this moment, a light clang sounded behind Zhou Bai's back. Zhou Bai immediately turned around nervously and looked over, finding that Alice was standing not far behind him, and accidentally kicked an iron tube under his feet.

Seeing Zhou Bai looking over, Alice raised her index finger and said, "Shh, don't be nervous, I won't tell the teacher."

"You... heard it?" Zhou Bai said.

Alice nodded: "Actually, I have always been skeptical about the so-called doomsday. There are some things you may be able to take a look at."

Zhou Bai followed Alice to a corner of the warehouse and found rows of bookshelves in front of him. His eyes lit up and hurriedly walked up: "Chinese...mathematics...chemistry...physics... are all knowledge-based books?"

Alice said, "Come and see this."

Then I saw Alice open a book, get a page of paper from it and send it to Zhou Bai.

Zhou Bai took the paper and saw that it was full of words.

"Don't open the door, he just wants to eat us..."

"It hurts so much... My chest is getting more and more painful, something is about to jump out..."
