Boys and girls run wildly down the hallway, red lights flashing overhead.

The two threw themselves into the elevator, and the boy jumped up and slammed the up button.

Zhao Gao regretted his negligence a little, and he finally relaxed his vigilance, which gave the patrol a chance, and the captain pressed the alarm, and the entire research institute began to enter a state of alert. Fortunately, tonight is the day of periodic shocks, everyone has gone to deal with the zombies and hunters outside the walls, and there is almost no one left in the institute, if they are fast enough, they can escape before the others can free their hands.

The elevator doors slowly closed and began to rise.

The boy breathed a sigh of relief that the elevator hadn't locked up yet, which meant they still had a chance.

2B held his hand tightly, his palms sweaty.

They are just children, even the slightly older Zhao Gao is only ten years old, and 2B is less than seven years old, and children of this age have just learned to dress themselves, are afraid of injections and medicines, and have to sleep with their parents at night. But Zhao Gao and 2B were covered in blood at the moment, and they were about to escape from a chaotic and sinister hell on earth, with pursuers behind them and zombies on the road ahead, they had no father, no mother, and no support, so they could only hold each other's hands tightly.

Zhao Gao thought that he was crazy to bring 2B with him when he escaped, and the institute was heavily guarded, if he could barely escape alone, then he would definitely die if he brought such a big oil bottle.

It's not that he didn't want to throw the girl away halfway, the only thing that didn't let him do it was his little self-esteem, since he said before that he would take her away, then he had to do it, otherwise wouldn't it be shameless to break his promise and go back on his word? Zhao Gao didn't want to lose face, let alone in front of a little girl.

The elevator was going up one by one, they were getting closer to the ground, the boy was getting nervous, it took about thirty seconds for the elevator to rise from the ground floor, it was enough time for the people on the ground to react, they just had to have the elevator door sealed with a gun, and they had nowhere to escape.

If the other party shoots at the elevator, there is nowhere to hide in the elevator car.

There is no doubt that they will do so.

They won't let anything underground escape to the surface.

The security guards were on standby.

The four men held their breath with their guns, their eyes falling on the elevator door through the scope of their automatic rifles, and everyone was nervous because they didn't know what was going to be the one who was coming up the elevator below.

There are only four of them, this is all the excess combat power that the institute can take out at this time, everyone else was sent to the wall to intercept the tide of corpses, tonight's periodic impact is more violent than ever, thousands of zombies are pouring up in waves, minefields and howitzers can't stop it, the soldiers have to climb the wall and shoot the approaching infected with rifles and machine guns, the situation is very serious, people can no longer care about a small alarm at the bottom of the institute.

The red LCD numbers on the side of the door beat one by one, and the security guards' hearts raced, and beads of sweat appeared on the tips of their foreheads and noses.

B3。

Three basement floors.

B2。

Second basement floor.

B1。

Basement level.

After a few seconds, the red LCD number jumped, turning into a "1" with a crisp sound.

Someone swallowed a mouthful of saliva, they were nervous but not flustered, and their guns were steady.

The elevator doors slowly moved to the sides, and the security guards breathed a sigh of relief, they were ready to be captured or killed, and if the people in the elevator dared to resist, they would shoot. The forefingers of the security guards slowly pulled the trigger, but then all of them were stunned, and the hands holding the guns couldn't help but relax.

The elevator doors opened, but the elevator car was empty and there was no figure.

No one? What's going on?

The security guards looked at each other, their eyes were suspicious, was there an empty elevator coming up? The four of them were a little surprised, they were squatting here to defend as if they were facing a great enemy, waiting for an empty elevator?

The empty car stopped there, motionless, the security guards were very cautious, did not rush to the elevator, the two sides were deadlocked for more than ten seconds, nothing abnormal happened, and finally the elevator door slowly closed again. But the red LCD number on the side of the door has been stuck at "1", which indicates that the elevator car has not left, and if no one else summons it on other floors, it will stay here.

The men looked at each other, was it really too nervous?

Someone stepped forward and pressed the down button, the elevator door opened again, and the empty car appeared in front of several people, and the security guards put away their automatic rifles and stepped into the elevator, looking around. The elevator was an extremely narrow space, and there was no way to hide anything, and they could see it from the outside, and the four Marines breathed a sigh of relief, but at the same time a little amused...... They take an elevator so seriously, it's a bit of a frightened bird.

"Is there anything out of the ordinary?" Someone asked.

The others tapped their fingers lightly on the wall of the elevator car and shook their heads.

"Empty, nothing."

"And who's calling this elevator?"

"Maybe the people at the bottom pressed the elevator and went out again, so the empty elevator came up." Someone replied, "The alarm on the ground hasn't been lifted yet, so let's go and turn off the other three elevators first." ”

The man nodded, he was a little tired, he wasn't on duty today, it was supposed to be a good rest day, and he was messed up by this damn periodic shock, and now someone in the underground research institute suddenly called the police, it was really a wave of unsettled waves.

The man closed his eyes and stretched his waist, yawned, and suddenly a warm liquid sprayed on his face and mouth, he was stunned, raised his hand and touched his face, his hands were full of scarlet.

He looked up in astonishment to see the man across from him staring blankly, leaning against the elevator wall and sliding slowly, blood splattering like a fountain.

Four strong, well-armed men with big shoulders and round waists were crammed into an elevator, so when the first person was killed, scarlet blood was all splattered on the faces of the other three, and the security guards were stunned by this sudden turn of events, and their brains went blank for a second.

In a second, the second person had his throat slit, and blood gushed out of the large artery on the side of his neck, coating an entire wall of the elevator like paint.

At some point, a small, thin figure appeared in the center of the four security guards, holding a knife in his hand, and the Marine with his back to him became the first to slash the man's neck. Then he spun around, and the knife pierced the second man's neck.

The Marines were trapped in the elevator and couldn't escape, they couldn't even get away, it was an extremely stupid decision for everyone to enter the elevator, the narrow car turned into the perfect death trap, everyone and Zhao Gao were within reach of his blade, and the Marines couldn't even lift their automatic rifles.

The remaining two finally came to their senses, screaming in horror and drawing their guns, but the narrow space restricted their movements, and the little black shadow swooped up, flipped over with one of them's head, and wrung his neck with its weight. The boy landed on the floor, pulled out the dagger from the corpse's waist, and threw it with his backhand, piercing the last man's eyebrows with precision.

The security guards fell to the ground, and a thin pool of blood accumulated on the floor of the elevator.

The boy stood in a pool of blood nonchalantly, raised his head and clapped his hands on the roof of the elevator car.

"Come down."

I don't know when there is a hole tens of centimeters square on the top of the car, the girl's dirty face appeared in the hole, she looked down hesitantly, the heavy smell of blood came to her face, and the elevator at this moment has become a bloody hell.

"Jump off." The boy said, "I'll catch you." ”

The girl nodded, climbed down from the hole, and then jumped into the boy's arms and hugged him tightly.

This is the trick played by Zhao Gao, he and 2B have been hiding on the roof of the elevator car, so the security guards failed to find them, and then Zhao Gao took the opportunity to jump down and kill them...... The security guards actually knew that there was a hole in the top of their heads, but they didn't suspect it, because the hole was used to transfer cables, and it was only a few tens of centimeters long and wide, and it was impossible for a person to pass through.

But they don't know that their opponents are just two children, and where they can't pass, the children can pass.

The child has the child's modus operandi.

There's nothing more terrible in this world.
