After leaving the hotel, Xia Yi and the other two came to the hospital not far from the hospital, entered the rooftop of a residential building, and observed the movements of the hospital.

Qiu Ruoyan found two chairs, and they sat on them, looking at them with a telescope.

"Will those mice really attack the hotel?" Yao Chenghe asked while standing.

"You will know just by looking at it." Xia Yi was too lazy to explain.

"Then aren't those people dead?" Yao Chenghe was a little happy. The rat group might not be able to kill the people in the hotel, but as long as you enter the hotel, you can definitely infect the plague to those people.

There are only a dozen sets of fire suits left, which will save at most ten people from danger.

"I wish I could have the rat pulled away." Xia Yi put down the telescope, and there was no movement in the hospital.

He was going to wait until early tomorrow morning, and if the rat group had not moved, he would have to break through.

Lying on the back of the chair, Xia Yi fell into thinking. He was a little confused about why the men with glasses wanted to do such a thing.

At first, when he heard Yao Chenghe's explanation, Xia Yi thought it was an relief medicine exposed, but if he thought about it carefully, it must be the conspiracy of the men with glasses, who wanted to force him away.

For what? The power of three hundred people? What is the attraction of the rule that ends in more than seventy days?

Xia Yi couldn't understand that the man with glasses must have had a special plan, and the man with glasses alone could not do such a thing. This is a conspiracy of a group of people.

If he was free, Xia Yi would definitely investigate it carefully, but he still had more important things to do now and had no time to care about a group of people who were about to die.

The relief medicine has been used up. You must get the raw materials before noon tomorrow to make relief medicine.

He said to Qiu Ruoyan and Yao Chenghe: "I'll watch here, you go and collect other medicines first."

"Okay." Qiu Ruoyan and Yao Chenghe agreed, and they got off the stairs and drove away.

Xia Yi ate a piece of bread and continued to observe.

An hour later, Qiu Ruoyan and Yao Chenghe returned after collecting it.

They drove two cars, and the small truck that Yao Chenghe drove was full of medicine, so they directly emptied a pharmacy.

There are also medicines that Yao Chenghe has not recorded before. All afternoon, Yao Chenghe was trying hard to record in the car.

In the evening, Yao Chenghe, sweat-covered, returned to the rooftop, took a bottle of water and drank in big mouthfuls.

Throwing the empty bottle aside, Yao Chenghe said to Xia Yi: "There is still a shortage of raw material. You just need to bring that one back."

Xia Yi gave Yao Chenghe the phone, converter and USB flash drive, asking her to determine what the difference was.

Yao Chenghe covered her head, looked through the ingredients of the confirmed medicine one by one, and eliminated it.

When the sunset was about to set, she finally finished comparing.

"Is this thing with code-name x missing?" She returned the phone to Xia Yi.

"x?" Xia Yi looked at his phone and saw an ingredient called x-111.

"Is it a confidentiality ingredient?" Qiu Ruoyan looked curiously.

"No matter what it is, there must be one in the research institute." Xia Yi was worried now whether the group of mice would destroy the raw materials.

The sun finally sank into the horizon. When the last ray of light disappeared, Xia Yi saw the rats in the hospital gathering at the gate.

Do you need to act?

For safety, Xia Yi first sprinkled gasoline around the rooftop.

Then, the three of them waited quietly.

After the sun sets, the moon appears quickly. The moon is a crescent moon, half hidden behind the clouds, with low visibility, but you can barely see the actions of the rats.

The rat group just gathered at the door and did not take action immediately. Xia Yi and the other two dared not relax and stayed up late to observe.

"Is there really someone living here?" Yao Chenghe talked about the topic.

"The isolation in the institute is done well. If possible, we can live in it." Xia Yi replied.

"This is the legendary place. The most dangerous place is the safest place?" Yao Chenghe said boredly.

"If you live inside, you must first prepare your escape route and pull the rope upstairs next to you, so that you can leave quickly even if you are in danger." Qiu Ruoyan thought about the necessary conditions for living in the institute.

The night was quiet, and in order not to attract the attention of the rats, Xia Yi and Qiu Ruoyan were happy to talk about the topic with Yao Chenghe.

"There's some movement!" Xia Yi found that the group of rats in the hospital, which looked like a black carpet, started to move.

The group of mice went out through the gate and headed straight to the direction of the hotel.

"It's true that I'm going to attack the hotel!" Yao Chenghe was excited.

"You're watching here." Xia Yi asked Yao Chenghe to stay here, and he and Qiu Ruoyan came downstairs.

They put on chemical protective suits and waited for the group of rats to walk away, and quickly went to the hospital.

There were still mice in the hospital. The two of them lit torches, entered through the main entrance, and successfully arrived downstairs of the institute.

"Squeak--!" The group of rats surrounded the two of them and made a huge scream.

The two of them looked at each other and breathed a sigh of relief.

They didn't know if the rats had followed the group of rats, so they deliberately walked in through the main entrance. Since there was no effective obstacle on the road, it proved that the rats were not there.

The two of them quickly walked upstairs, and Xia Yi knocked on the sealed door on the sixth floor.

They have no means to open the door, nor have they contact the women inside the door. If the other party does not open the door for them, their actions will fail.

Fortunately, the woman was mentally weak and had poor sleep. She heard the sound and quickly opened the door.

He drove away the rat behind with a torch, and Xia Yi quickly walked inside and closed the door.

Looking at the woman, he took three seconds to come up with the name of the woman that Gao Shou had said.

Bai Wan, a name that suits the temperament of the other young woman.

"You are back!" Bai Wan opened her arms and rushed towards Xia Yi excitedly.

Qiu Ruoyan grabbed Bai Wan's shoulder in time and stopped her.

"There may be viruses on the clothes, be careful." Qiu Ruoyan said seriously.

Bai Wan then noticed Qiu Ruoyan. Because the chemical protective clothing was tightly wrapped, she did not see Qiu Ruoyan clearly, and now she realized that she was a woman.

She became alert inside.

Xia Yi is the first living person she has seen these days, and she is a man. She has a happy last time, just like men in the end of the world always want to possess women when they see women, and she also wants to possess Xia Yi.

She compared Qiu Ruoyan. The other party was not inferior to her in appearance, and she was younger and more beautiful than her. As for her figure, she couldn't see clearly because of her chemical protective clothing.

"We came here to find a drug codename x-111." Xia Yi said straight to the point.

"Don't you live here?" Bai Wan was concerned about this issue first.

"After getting the medicine, I may live here." Xia Yi replied.

This sentence made Bai Wan happy. Only then did she realize the most critical question: "What do you want x-111 to do?"

"We can make relief medicine, but this material is missing." Xia Yi glanced at Bai Wan and turned his eyes elsewhere.

Because he got up from the bed, Bai Wan's clothes were a little untidy.

Qiu Ruoyan stood in front of Bai Wan: "We took advantage of the rat's absence and time was limited."

"Oh, that medicine is a small black bottle, in the No. 3 laboratory on the fourth floor." Hearing that time was limited, Bai Wan swallowed the chatting thoughts and told the two of them the location.

"Thank you." Xia Yi and Qiu Ruoyan put on chemical protective clothing, opened the door and walked out.

Bai Wan closed the door, and the surroundings suddenly became quiet, and the smile on her face disappeared.

Resting against the wall for a while, she came to the incubator and looked down through the glass.
