After Shi Guangrui left the emergency room, he tiptoed towards the stairs.

He didn't even know what was going on upstairs.

Before leaving, Liu Zhenze only gave him a brief introduction to the situation on the second floor.

After a while, Shi Guangrui had already come to the corner of the first and second floors.

Although he had carefully checked the door before coming up to make sure that no living corpses had broken into the building last night, human instinct forced him to cautiously advance towards the second-floor pharmacy while on guard.

When Shi Guangrui came to the corridor on the second floor, he clearly saw the bodies of two living corpses lying in front of the toilet door on the right-hand side.

Shi Guangrui muttered quietly.

"It seems that these are the two 'pseudo-corpses' that Wei Tianci's kid and Liu Zhenze killed."

Shi Guangrui didn't pay much attention to the corpses on the ground, and he immediately walked towards the end of the corridor on the left.

"Squeak... Gah..."

The door of the pharmacy was opened, and a strong smell of disinfectant suddenly entered Shi Guangrui's nose.

Shi Guangrui said to himself.

"It smells like a potion."

"Hurry up and find the injectable glucose."

"Just go back to Zhang Cancan's side immediately."

As soon as he said that, he began to rummage through the pharmacy.

Because Wu Minmin had already told Shi Guangrui the general location of the medicine cabinet where glucose was stored, it saved him a lot of convenience.

Shi Guangrui walked directly towards a medicine cabinet in the corner, he stood in front of the medicine cabinet and began to examine it carefully, he kept repeating as he checked.

"Glucose..."

"Glucose..."

"Glucose..."

"Okay, I've finally found you!"

Shi Guangrui looked at the medicine cabinet opposite him through the glass with a happy face, and there were several glass bottles in it, and a boxy piece of paper was pasted on the top of the bottle, and there were a few big words on the paper: 'glucose for injection'.

When he happily went to pull the door of the medicine cabinet, the cabinet turned out to be locked.

Shi Guangrui said angrily.

"Damn, why are you still locked."

"Do you want to go down again, and ask Mr. Wu where the key is."

Shi Guangrui looked at the bottle behind the glass helplessly, obviously close in front of him but couldn't get it, which made people very aggrieved.

The more Shi Guangrui thought about it, the more angry he became, and he didn't plan to go to the first floor to find Wu Minmin to get the key.

I saw him clench his hands into fists and slam the elbow of his right arm against the glass on the medicine cabinet.

"Split... Village... Syllable... Ahh

After the sound, Shi Guangrui patted the glass ballast on his right arm with his left hand.

Then, one by one, he put the glucose for injection into a white plastic bag, which Wu Minmin handed to him before leaving.

Before leaving, Shi Guangrui didn't forget to look back at the whole picture of the pharmacy, and then he quickly walked downstairs.

In front of the emergency room on the first floor of the infirmary.

"Uh... For... Whew..."

There was a regular knock on the door, which alarmed the three people in the emergency room.

Liu Zhenze said to Wu Minmin.

"The knock on the door was even, and it was determined that it was not a living corpse."

"The president is back."

"Teacher Wu, go and open the door."

Wu Minmin immediately ran to the door and asked vigilantly once again.

"Are you?"

Shi Guangrui's voice came from outside the door.

"Teacher Wu, open the door!"

"Who else could it be if it wasn't me?"

The moment the door opened, Shi Guangrui walked in eagerly.

He ran to Zhang Cancan's side as soon as possible, looked at Zhang Cancan lying on the bed, and Shi Guangrui asked.

"Hungry?"

"Are you thirsty?"

Zhang Cancan nodded at him, and then replied.

"Hungry, not very hungry."

"It's just that my mouth is dry and I want to drink water."

Shi Guangrui took out a bottle of glucose for injection from the plastic bag he was carrying, and he immediately helped Zhang Cancan up after opening the cap.

After Zhang Cancan was helped up, Shi Guangrui immediately sat behind her and let her lean on his body.

Then Shi Guangrui took the glucose in his left hand and slowly fed it to Zhang Cancan.

Wu Minmin watched and laughed from the sidelines.

The people present had always lived in the same dormitory building.

Shi Guangrui takes such a gentle care of people, Wu Minmin has seen it for the first time.

In fact, it is not only Wu Minmin, but even Liu Zhenze is the first time to meet such a gentle and considerate student union president.

Shi Guangrui saw Wu Minmin secretly laughing at him on the side, and he asked.

"Teacher Wu, what are you laughing at?"

Wu Minmin replied.

"It's the first time I've seen you like this."

"I don't want to be the one before, arrogant and unreasonable."

"Actually, you don't have to be so careful."

"After a night of recovery, Cancan is ready to get out of bed and move."

Hearing Wu Minmin say this, Shi Guangrui immediately looked at Zhang Cancan.

Shi Guangrui asked.

"Are you feeling better?"

Zhang Cancan nodded at him and said nothing.

Shi Guangrui continued happily.

"That's great!"

"Let's take a bottle for each person, and replenish water and energy first."

Shi Guangrui distributed the glucose in the plastic bag to Wu Minmin and Liu Zhenze.

The short-term physical needs have been replenished, but this is not a long-term solution.

In order to get out of here, the four people in the room still have to come up with a good escape plan.

At this time, everyone's eyes fell on Liu Zhenze's side.

Liu Zhenze said to them helplessly.

"You don't want to look at me, just the environment we are in now."

"It's just that you can't go there."

"If you want to go back to the student cafeteria and meet them, just kill as many living corpses as you can outside the window."

"So we can go around the back of the infirmary and safely head towards the student cafeteria."

Zhang Cancan slowly got off the bed, and she asked Liu Zhenze.

"There are so many living corpses, even if they are killed one by one, they will be exhausted to death."

"What's more, the only person we can fight here is Shi Guangrui himself."

Liu Zhenze replied to Zhang Cancan.

"So, we have to think of a way to kill the living corpses en masse."

Killing living corpses in groups, Liu Zhenze said easily.

But it's really hard and hard to do.

However, all difficult things have a turnaround, and it depends on whether the parties can find out.

Shi Guangrui's mind kept thinking about the scene just now, and suddenly he said to Liu Zhenze.

"Zhenze, did you say that you can burn those living corpses with fire?"

Liu Zhenze thought for a while, and he replied to Shi Guangrui.

"Theoretically, it is possible to use fire, as long as the fire is big enough, it can burn living corpses to charcoal."

"The point is, where to make a fire?"

Wu Minmin suddenly thought of something, and he said to Liu Zhenze.

"I have a disposable lighter in my desk."

"This is still the last semester, and I caught a classmate smoking in the back of the infirmary building, and I didn't get it!"

Liu Zhenze interrupted.

"Mr. Wu, even if we have lighters, it's useless."

"We also need fuel to support combustion."

Shi Guangrui said to the other three with a smile.

"I know where the combustible material is, but I'm not sure if it burns."

Zhang Cancan asked Shi Guangrui.

"What are you talking about?"

Now Zhang Cancan has completely lost the bad attitude towards Shi Guangrui before, and even talking and asking is already very easy-going.

Shi Guangrui asked Wu Minmin.

"Mr. Wu, I want to ask you something."

Wu Minmin replied.

"Just ask, and I'll tell you everything I know."

Shi Guangrui then asked.

"Can medical alcohol be lit with fire?"

"I know industrial alcohol is definitely fine, but medical alcohol is usually 75 proof."

"Can you light it?"

When Shi Guangrui said the words 'medical alcohol', everyone felt hopeful, because they knew very well that there were many barrels of medical alcohol upstairs.

If the operation is successful, not only will the four people in the infirmary be able to return to the student cafeteria unharmed, but it will also wipe out nearly half of the living corpses in the academy.

Wu Minmin immediately answered Shi Guangrui.

"Medical alcohol is also very easy to burn when it encounters an open flame."

"So, you need to make a trip upstairs."

Shi Guangrui nodded and replied to Wu Minmin.

"It's okay, I'll just make another run."

"As long as I can save Cancan, I'm not tired."

After speaking, Shi Guangrui ran towards the door with a smirk.
