Chuchu and Gu Tianye did not go back to the bath center directly, but went to another place. There was no one or zombies in this place, so they climbed in directly through the window.

This is a pharmaceutical laboratory. The things on the laboratory table have not been put away yet. One can tell from the neatness that someone was doing an experiment before, but for some reason, there was no time to tidy it up.

Gu Tianye touched the experimental table, which was covered with thick dust. There were also mottled footprints on the ground where someone had walked.

"What experiment are they doing? What happened that made the staff leave in a panic?" Gu Tianye is also an experimenter. He would never do this. Even if there is a huge emergency, he will definitely put away the things on the laboratory table before leaving the laboratory, unless his life is in danger!

Chu Chu knew nothing about the medical industry. She blinked and looked at Gu Tianye, "Do you think it's because of the sudden zombie invasion that they forgot to pack up?"

"That doesn't seem right. Zombies are emotionless creatures. It's impossible for them not to destroy the experimental bench!" Chu Chu felt more and more that there was a huge secret hidden in this pharmaceutical factory. She frowned, thinking that there must be something she had overlooked!

Gu Tianye spent the whole day here without finding any valuable clues. Did he waste his time tonight?

In the thick dust, a piece of paper was faintly revealed. The paper was handwritten, and the font on it was very messy. It was obvious at a glance that it was written at the intersection!

"Hello everyone, by the time you see this, I will most likely have already left this world. However, what follows is very important, and I hope you can remember it!"

"The pollution in this world is getting worse and worse, and the source of all this pollution is the pharmaceutical laboratory. Due to the failure of developing certain drugs, the virus has leaked out, and the human body has become rigid and blood-sucking. I can't reveal too much about the specific situation. I hope you can create an antidote as soon as possible!"

"The formula that caused the virus to leak is hidden in the laboratory. I hope you can find it and make the corresponding antidote based on the above formula!"

"I know it's a bit difficult to put this responsibility on you. If you can't solve it, please don't tell anyone else!"

Chuchu and Gu Tianye looked at each other in surprise. They thought that the zombie virus was a virus in nature, but they didn't expect that there was another hidden secret!

"No wonder we were brought to the lab to research an antidote. I thought they had already figured out what the zombie virus was..."

Gu Tianye recalled what happened back then, and the more he thought about it, the more wrong it seemed. There was no zombie virus at all back then, so where did they get the sample from?

Now after reading this person's letter, he suddenly realized that the virus had already appeared a long time ago, but it had not entered everyone's field of vision.

Chu Chu also gasped, "I don't understand, why are they researching this drug? What benefits does this drug bring to them?"

She frowned, the more she thought about it, the scarier it seemed. Could it be that someone did this on purpose? Did he want to turn the whole world into a world of zombies?

"We must find the prescription now!" Chu Chu knew that she didn't have much time to feel sorry for the world. What they had to do was to find the medicine as quickly as possible, faster than others!

Gu Tianye and Chuchu searched the entire laboratory but found no prescription.

"Could the prescription have been taken away by someone?" Chu Chu kept staring at the letter after saying this. Could they have overlooked something important?

Gu Tianye definitely had this possibility, "Chu Chu, why don't we come over tomorrow during the day and visit the old man in the white coat. He must know a lot of secrets!"

Chu Chu nodded, "Okay, then come back tomorrow during the day!"

Chuchu picked up the letter and put it away. Such a valuable thing cannot be seen by others!

After returning to the bath center, Chuchu asked Xiaobao, Xiaobao's grandmother and Song Jiaer to go back first, and the others stayed here.

Although the two bathing centers are far apart, they have a secret passage, so you can come whenever you want. As long as there is a center in the world, the world will be yours!

They gave the letter to the cowboy and asked him to see if he could find any clues.

The cowboy stared at the words above and suddenly felt that the handwriting was very familiar, as if he had seen it somewhere.

"This looks like the handwriting of our lab professor. I've seen his handwriting before, it's definitely there!"

The more he spoke, the more certain he became that these words were the professor's. If that was the case...

"Boss Chuchu, where did you find him?" The cowboy looked at them nervously, "Have you seen him?"

The cowboy guy and the professor have a good relationship. In addition to being teacher and student, they are also friends, so the cowboy guy became so excited after seeing this letter!

"We saw this letter in a pharmaceutical laboratory. Tomorrow we decided to visit an old man who has been working at this pharmaceutical company. Let's see if we can get some secrets out of him!"

Chu Chu looked at the cowboy and invited him, "Do you want to come with us?"

The cowboy man is not in any physical condition now, so no one restricts his behavior. He can do whatever he wants now, and Chuchu also feels more at ease with him by her side.

The next day, the three of them brought some hot food and came to the door of the pharmaceutical company again. The door opened automatically.

The three of them looked at each other and walked in without any hesitation.

After they went in, the door swung back and closed automatically.

"Welcome to the pharmaceutical company, friends, please come in!"

As the voice appeared, the old man in a white coat who had received them yesterday waved at them from the window!

Several people entered without any hesitation. As soon as they entered, the old man in the white coat smelled a fragrance. Although he had already eaten breakfast, he was still unconsciously attracted by this fragrance!

"What did you bring? Don't you know this is a laboratory and you are not allowed to bring food in!" The old man was obviously very concerned, but the action of him secretly licking his lips still betrayed his inner thoughts!

Chuchu put the insulated lunch box on the table. "There's nothing delicious today. It's just some eggs, milk, noodles and other things. We're getting tired of them!"

"Are you going to eat it or not? If not, I'll feed it to the zombies!" Chuchu took out the things one by one, and the aroma was even more tempting!
