As soon as the group descended to the twelfth floor, they heard a violent knock on the door from below, and the sound of hitting the door was very loud, giving them the feeling that the door would be easily broken in the next second.

Eventually, this became a reality.

In the next second, the door broke with a "bang", and the sound of dogs barking came to the face.

"Throw chairs! Block the hallway! Zhang Yichi roared, and hurriedly threw a chair at the corner of the corridor, and the other two hurriedly did the same. In just ten seconds, dozens of chairs were thrown down and blocked around the corner.

Before they could catch their breath, a large wave of dogs of various kinds had already rushed downstairs.

The chairs roughly blocked the staircase, but there were gaps in between. The big quilt head stuck into the gap and barked wildly, and the smaller one rushed directly through the gap.

Lezer reacted the fastest, and swept back the three dogs that pounced on him with a stick of black blood. The strength of the black blood was so great that of course it not only swept it back, but also killed it directly with a stick, and by the way, it also pushed back those who pounced on it.

Zhang Yichi's phantom weapon turned into a long knife again, and anyone who could drill through the chair was slashed to the ground.

Zheng Jiang was not idle, there were too many dogs, and there was a posture of forcibly breaking the chair barrier, so he kept throwing the chair down one after another and continued to strengthen the barrier. If the obstacle is broken, then in an instant, hundreds of dogs will rush up, and two punches are invincible to four hands, and they will not be able to parry at all.

"How many?" Zheng Jiang asked as he threw it.

"No less than a thousand!" Zhang Yichi roared, "Lai Zeyin, try your rain cannon!" ”

"No, the rain cannon belongs to the category of superpowers and cannot be used!" "If I could have used it a long time ago, would I still use it here?" ”

"Eh, what's that?" Zheng Jiang stopped the movement in his hand and pointed downstairs and said.

The dog's body downstairs was suddenly covered by a dense group of insects, which made a rustling sound and were stepping on the dog's body to climb up. Spiders, cockroaches, centipedes, beetles...... Everything they've seen is now all in one place.

Such a scene, even the three of them, the scalp was numb instantly.

"Retreat, retreat, retreat!" Zhang Yichi pulled Lezein and began to retreat.

Bugs are not terrible, and they are usually stung with a small red envelope. But this is only one case, and now thousands of bugs are rushing at it. The chair can keep out slightly larger animals like dogs, but bugs can easily burrow through cracks.

"What to do?!" Zheng Jiang ran to the front and asked hurriedly.

"No problem! Throw the chair down or something, at least block the dog first, and as for the bugs, it shouldn't be a problem if we close the door! Zhang Yichi thought that there were countless disgusting insects chasing them behind him, and his back was cold.

"That's all there is to it." Lezein is also cowardly now, he doesn't want to be surrounded by insects for a while, he is still good at insect stings, he is afraid that he will have to find a hole to drill into his body, and then there will be spiders and centipedes crawling around in his stomach...... It's unimaginable......

When he ran to the thirtieth floor in one breath, Zhang Yichi glanced at the fire extinguisher at the entrance of the building, and he stopped: "Wait." ”

The other two looked at him, then followed his gaze to the fire extinguisher, "What do you want to do?" ”

"Try it." After that, Zhang Yichi went to the staircase and picked up a fire extinguisher, and Lai Zeyin and Zheng Jiang also went over and picked up one each.

"Can it be done?" Zheng Jiang asked with some apprehension.

"......" Lezein had already shaken the bottle barrel, unplugged the safety bolt and tried.

In an instant, the corridor was filled with white gas, Zhang Yichi covered his mouth and went up another level: "I'll rely on ......"

"It doesn't feel bad." Lai Zeyin also went up another layer with a fire extinguisher, and Zheng Jiang followed closely.

"Ahem!" Zhang Yichi coughed a few times, "Ready, in a while, Lai Zeyin will be in charge of the left and right walls, Zheng Jiang will be in charge of the top, and I will be in charge of the insects on the stairs." Remember, let's get back as we spray, don't stand here stupidly, you'll choke to death before you kill the bugs. ”

As soon as he finished reminding, the sound of squirming came again, mixed with the barking of dogs.

"Ready!" Zhang Yichi roared, and the fire extinguishers of the three of them were all aimed downstairs.

Ten seconds later, five or six dogs came galloping up.

"Squirt the girl!"

"......"

"......"

"......"

Three strands of dry powder sprayed out and poured directly into the dog's mouth.

"Stand back, don't let go!" Zhang Yichi said.

The group fought and retreated, and a few dogs did not come out of the white powder mist, presumably having been dealt with.

When it was sprayed on the thirty-second floor, Zhang Yichi called the others to stop, and there was no movement in the white powder mist. Of course, not moving does not mean that these tens of thousands of bugs and thousands of dogs have been killed, it is not that simple at all.

Another layer was withdrawn, and when another batch came up, they continued to spray dry powder. After repeating this several times, there was obvious results, and the entire corridor was filled with white mist.

Coming to the forty-second floor, there were the most chairs here, and the chairs taken from the conference hall were piled up here, except for a small aisle on one side of the staircase.

"Plug this place, the dogs and other things can't come up, and there won't be many bugs left, and they won't be able to open the door at all." Zhang Yichi put the fire extinguisher aside, blocked the narrow aisle that was originally left, and then lifted the fire extinguisher and knocked on the door.

Rika opened the door and saw the embarrassed trio and hurriedly let them in. Once inside, he locked the door and pushed back one of the desks that had been in front of the door.

"Whew...... Call...... Basically settle ......," Lezein said as he lay on the ground.

However, apart from the three of them, no one responded to them at all.

Zhang Yichi didn't sit down, he wasn't tired enough to collapse.

"What's the situation?" He asked.

Lihua on the side pointed to the unpredictable side of the curtain wall: "The situation is not good, you can go and take a look." ”

Hearing this, Zhang Yichi didn't care about resting, and came to the curtain wall with others. Mo Tu has been standing here and has not left.

"Ah, they've already attacked the Vault, and they're destroying and decaying, and with sheer numerical superiority, there's almost no grass growing in their pass. Ah, the shelter isn't too bad, most of the people are dead, and the others are scattered and on the run, and it won't be long before they're all going to burp. By the way, how long is left? Mo asked him.

After listening to the unpredictable description of the shelter situation, Zhang Yichi looked at the time and said, "Seven thirty-five." ”

"It's less than half an hour, and when they're done with the Vault, I guess the finger will be pointing at us." Mo Ji turned around and walked towards the conference hall, "Let's go, take a break in the conference hall and prepare, a while is the most critical moment." ”
