The smell of blood, the stench of corpses, and the stench of other indescribable deterioration permeated the air and seemed to be visible to the naked eye. When Ye Yuyao breathed in the rotten air again, he felt a tumbling in his stomach.

She couldn't help but wonder if she could get infected by breathing this air. But the people who came back from the school building before were fine, and the incubation period aside, maybe the virus didn't spread through the air.

"Click"

With the sound of the iron door closing, the howl of the zombies was also cut off, and the corridor suddenly became quiet, and even the breathing of the people around could be heard. When I first came out of the warehouse, the howls of zombies were already clear in my ears, needless to say, the campus was already densely packed with zombies. Fortunately, the laboratory building was near the warehouse, and they didn't attract the attention of the zombies.

"What's next? ＂

Zhang asked if it was a bit surprising that he was here. When Ye Yuyao and the others were about to go out, he walked over with a fire axe.

"You may be short of a helper. He said, "I'm not for Deng Deqiang, I just think that without me, you may not come back alive." ＂

Although these words were a little arrogant, Ye Yuyao and the three of them were quite relieved to hear it. In addition to being relieved, for Ye Yuyao, the addition of tension made her feel a little uncomfortable, she still remembered what happened last night very clearly, and even that feeling was still in her hands, but she couldn't refuse his joining because of this. In fact, Chen Tao also feels the same way.

Since he joined temporarily, Liu Shaoqing decided to set off first, and then tell him about the relevant plans.

"It seems that the zombies didn't enter the school building again, so let's go up to the third floor first, and then go to the school building through the flyover, find a classroom and throw chairs down, and we have to do this without a sound system. ＂

Liu Shaoqing explained their plan to Zhang Li. The infirmary's location is on the first floor of the dormitory, and there is a separate door outside, so you don't have to enter the dormitory. But then the trouble also came, the dormitory building is on the other side of the campus, there is a teaching building in the middle, if you want to go to the dormitory building, either pass through the teaching building, or take the road on both sides of the teaching building, one side is the open space in front of the teaching building, and the other side is the small garden behind the teaching building. Between the laboratory building and the teaching building, there is a bridge to connect it, because there are too many zombies near the teaching building, so they plan to enter the laboratory building first, and then enter the teaching building through the overpass.

"Words from the third floor...... Several classrooms were empty and the doors were not locked, and it is not clear what was going on right now, but the doors should not be locked. Ye Yuyao recalled the situation when he was in the teaching building before and said.

"Then once you enter the third floor, you will lead the way. ＂

After Liu Shaoqing finished speaking, Ye Yuyao said "um".

"Although we can't hear anything right now, there's no guarantee that there won't be a threat, so we still have to keep quiet. ＂

The other three nodded, and then followed Liu Shaoqing up the stairs. Liu Shaoqing is in front, Ye Yuyao is in the middle, and Chen Tao and Zhang Lidian are behind. This was arranged by them before, but because of the addition of tension, there was one more queen.

They held their weapons and walked up the stairs step by step, nervously tense. Every time he came to a corner, Liu Shaoqing signaled them to stop, then poked his head out to observe the surroundings, and only after confirming that it was safe did he let them continue to follow him upward.

After 15 minutes, they finally reached the third floor, which took five times as long as before. Along the way, I didn't see a single zombie, maybe it was really around the teaching building as Liu Shaoqing guessed.

After entering the third floor, Liu Shaoqing first moved to the entrance of the overpass, and then looked at the corridor carefully, although the corridor was dark, it was empty, and the window at the end of the corridor was shining in the same pale daylight as on the overpass in front of him, and the corridor seemed to be safe.

Liu Shaoqing beckoned to the three of them, and they followed, followed by Liu Shaoqing, and the four of them entered the overpass.

Even when they reached the overpass, they didn't dare to straighten up, and the zombies seemed to crowd the open space under the overpass, and their howls rose up like evaporating water vapor. Ye Yuyao felt that if he stretched out his hand outside the parapet of the overpass now, he might be able to feel the rising voice.

When they entered the school building, the howls of the zombies were left behind.

People finally dared to straighten up, their legs aching and numb after a long period of sneaking, and they were dizzy when they got up. The scene on the third floor was no different from two days ago, except that there was a layer of lime on the ground, which was full of messy footprints, and there were some cracks in the ceiling, and it looked like the helicopter must have fallen upstairs. If possible, Ye Yuyao would like to go up and have a look, and maybe he will find something useful.

But today their destination is not there, and who knows what danger will be in the vicinity of the wreckage of the helicopter.

According to his impression, Ye Yuyao pointed to a classroom not far away, and several people immediately moved there. Liu Shaoqing stood in front of the door, and the others leaned on both sides to prevent emergencies. Liu Shaoqing knocked on the door first, and when he saw that there was no movement, he reached out and pushed it away.

As Ye Yuyao remembers, this door is not locked. Liu Shaoqing pushed the door while observing the situation inside. He quickly glanced around the room, and there were no zombies inside, except for some clutter.

After confirming that it was safe, the four of them got in one after another, and then locked the door.

"Whew...... ＂

The four of them breathed a sigh of relief, and the nerves that had been tense finally relaxed.

"The mirror...... Is it still with you? ＂

After a short rest, Liu Shaoqing asked Ye Yuyao.

Ye Yuyao opened his backpack and looked at it, the mirror was shining with silver light inside, and his clear eyes were just reflected on it.

She nodded and zipped up her backpack.

"Well, then as I said before, Ye Yuyao, Chen Tao, the two of you will go to the school infirmary to get medicine, Zhang Li, you and I will throw chairs below here to attract zombies, cough cough, I was worried that it was not safe for a person to be here, but fortunately you came." ＂

Zhang Zhang didn't speak, just glanced at Ye Yuyao and Chen Tao slightly. However, Ye Yuyao was relieved when she heard this arrangement, to be honest, she was a little resistant to being alone with Zhang Li.

"We throw it about every 5 minutes," Liu Shaoqing, who didn't know it, didn't notice anything, but continued to arrange, "After you finish taking things, use that mirror to remind us, and then we will meet on the second floor of the laboratory." ＂

The two said they understood, and then Liu Shaoqing walked to the window, opened the window, picked up a nearby chair, found a vacant space downstairs, and threw down the chair in his hand.

"Bang dang! ＂

The chair smashed on the ground and made a crisp sound, Liu Shaoqing didn't expect the sound to be so abrupt, and he was taken aback. Not only him, but also the zombies wandering in the open space in front of the teaching building also noticed that this loud sound, which was different from the low howls around them, stimulated their few cranial nerves, and they seemed to be running for a long time suddenly changed their programming, stopped wandering aimlessly and endlessly, dragging their staggering steps, and gathering towards the place where the chair fell little by little.

"They're drawn over. ＂

Liu Shaoqing looked at the zombies gathered downstairs and couldn't help but wonder what kind of scene it would be if it was a living person who fell. Then, he turned around and continued to Ye Yuyao and Chen Tao:

"You're ready to go. ＂

"Hmm. ＂

Ye Yuyao answered, put on his backpack, took the crowbar that Chen Tao gave her, and left the classroom with Chen Tao.
