Zombie Crisis Doomsday

At the same time, the sixth floor.

Zhang Yu sat on the steps of the stairs.

He quietly poked his head out from the corner of the stairs on the west side and stared at the zombies in the east corridor carefully, memorizing every move they made.

Zhang Yu made a discovery. There were more than 300 zombies on the sixth floor. Of course, these data were clearly visible under his nose. The lack of explicit data was the biggest hidden obstacle to this operation.

What Zhang Yu is worried about is whether there are still zombies in the classroom.

He took out a piece of paper from his arms, which was full of patterns. The patterns on the paper were all what he had just drawn for this operation - the internal structure of the teaching building, the appearance of the teaching building, etc.

As shown on the paper, except for this floor, each floor of this teaching building has five spaces, including three classrooms.

Three classrooms are in the center of the stairs on both sides of the teaching building, and the remaining two are toilets, divided into male and female toilets.

They are distributed at the ends of the stairs on the east and west sides of the teaching building.

This floor is special, there is no toilet on this floor.

According to Zhang Yu's observation, the space on this floor seems to be used in three types: library classroom, computer classroom and teacher's office.

There is only one teacher's office in this teaching building. From what Gu Zhangyu saw, the area of ​​this office was quite large. At first glance, it was at least no less than two hundred square meters in size.

This teacher's office is at the end of the stairs on the west side of the corridor, which is also at the end of the corner where Zhang Yu is currently located.

Although the stairs are still extending upwards and there are steps extending up, the stairway has been locked tightly by a large iron door, and it has also been tied with large black iron chains and covered with black paint.

Paint a lock the size of a fist.

Zhang Yu thought that the space above is probably the rooftop.

Since the stairway leading to the rooftop is blocked, the stairway on the other side should also be blocked. It is impossible for the school administrator to let primary school students run to the rooftop to play. If they are not careful,

Something happened, "The school allowed primary school students to play on the roof, accidentally slipped and fell, and died tragically!"

The school cannot afford such pressure from public opinion.

There is only one library classroom at the end of the corridor on the east side of this floor. Although there is a staircase in the middle, it seems that the library classroom is connected to another classroom on the side of the stairs... at least it looks like it on the publicity drawings.

That's right.

Vaguely, Zhang Yang seemed to have guessed the school's purpose of doing this.

At this time, most of the zombies were gathered on the east side of the corridor on this floor. From the looks of it, it seemed that they were not attracted by the explosion of the coconut, but because there was something on the east side that attracted them.

thing.

That thing is—a living human being.

Zhang Yu was not discouraged, because his first purpose of detonating the potion bag was actually to attract all the zombies to the east, and then empty the west corridor. In this way, it would increase the space for them and others to move.

A little.

Although detonating the earthenware pack can also kill the zombies on the east side of the teaching building, according to Zhang Yu's purpose, this is actually just a side trip. Because these zombies alone cannot stop the implementation of Zhang Yu's plan.

.

After observing for a long time, Zhang Yu finally confirmed that there was no zombie in the other classrooms on this floor, or that there had been one, but because of the booming sound when the 'coconut' exploded, the zombies who were originally there were

They were all attracted out of the classroom.

Zhang Yu laughed coldly, and just as he laughed, a purple-red thunder suddenly flashed across the sky, and the red flash illuminated his face, not to mention how sinister he looked.

After a blink of an eye, a deafening muffled sound suddenly sounded from the sky, like the beating of a huge war drum, which was heart-stirring.

Hearing the thunder, Zhang Yu noticed that the sky had turned dark, and no trace of sunlight could be seen at all.

Yes, the world has returned to a time without a trace of sunlight. It seems that an aura full of chaos is tightly wrapping the sky, increasing the atmospheric pressure in the sky. This feeling... is very depressing.

Zhang Yu took out a cylindrical tube as big as a baby's arm from his backpack. This tube was very beautiful. The surface was covered with a layer of crystal clear glass. What was placed inside looked like a mercury pillar, but it also looked like

Something is wrapped in a layer of metal, which glows silver in the air and looks very magical and strange.

Zhang Yu stared at the tube closely, and then began to turn it slowly. After turning it for half a turn, Zhang Yu stopped turning, as if something had been fitted. At this time, the inner metal substance wrapped by the glass

A red light suddenly appeared, shining brightly in this small space.

But in fact, they are just some numbers glowing red - 00:4:59:99.

The red light flickers on and off, flickers on and off. As the red light changes, these numbers are also changing, they are decreasing, they are gradually decreasing, like an electronic clock counting down. At this time, they have changed

It’s done—00:4:29:56.

Zhang Yu shook his head mockingly, laughed bitterly, and stood up with one hand on the wall.

He looked at the gray sky and murmured to himself, "I don't know if I can still live, or if I really can't penetrate this cage..."

Speaking of the latter, he gradually shifted his gaze and aimed it at this staircase, "Then, let's isolate ourselves from here..."

After saying that, he threw the countdown tube down the stairs.

The pipe fell down, rolling down the steps one after another. The sound of the pipe coming into contact with the tiles as it fell made a clanging sound in this silent space, not to mention how harsh it was.

"Come on, you disgusting guys, come after me, there is fresh human flesh here!"

Zhang Yu jumped out from the corner and shouted at the zombies on the east side.

At this time, the tube had stopped rolling down and was lying quietly at the junction of the stairs between the fifth and sixth floors. The red light was still flashing, and the numbers on the wall of the glass tube were still there.

It was constantly going backwards, and the only thing that made people care about it was the red light, which was flickering and looking particularly dazzling in this almost dark space.

Hearing Zhang Yu's voice, the zombies on the east side of the corridor turned their heads blankly, but only a few came towards Zhang Yu.

On the contrary, the children in the classroom, as soon as they heard Zhang Yu's voice, they immediately screamed crazily, a policeman came to save me, and a bad boy came in to eat people.

Mixed with crying as the soundtrack, not to mention how sad, sad and pitiful it is.

To Zhang Yu, these voices were undoubtedly hateful. They ruined his plan. You know, zombies...

Amid the screams of the children, these zombies knocked on the door even more crazily, and the students inside screamed in even more fear. The sound became louder than the previous wave.

At this time, many zombies gave up walking towards Zhang Yu and turned back, continuing to crowd in the pile of zombies and roar wildly.

Zhang Yu gritted his teeth, took off the silencer installed on the pistol, and fired several shots at the ceiling.

At the same time, all the zombies on this floor were startled by the gunshots. They all stopped their movements and looked blankly at Zhang Yu, but their hands were still facing Zhang Yu.

Hold the door to that classroom.

These guys seemed to be thinking about which side it would be better to attack.

Zhang Yu continued to shoot in the air, and at the same time roared loudly, "Students, please hide quietly in the classroom, listen carefully to the teacher's words, don't say a word, don't even make a sound, police

Uncle will give these cannibal bad boys a good lesson!"

"After teaching them a lesson, they have to tell their father to spank them hard, so the students should be quiet! Don't say a word, don't make a sound!"

After saying this, there was really no sound coming from the classroom over there.

At this moment, Zhang Yu fired into the air again, then took out the sharp knife from his pocket, and then used it to cut his left wrist severely, causing a large piece of scarlet flesh to turn up.

The red blood gushed out like a flooded faucet.

Zhang Yu's brows were twisted into a circle of wrinkles. Unable to hold back the heartbreaking pain, he suddenly screamed crazily.

"Ouch!"

The zombies started to go crazy. They rushed towards Zhang Yu crazily. Except for Dadu, they all rushed towards the west of the corridor crazily.

The air over there is filled with this strong smell of blood. It is this smell that has deeply stimulated the bloodthirsty habit in their genes. The closer they get, the stronger the smell becomes.
