Chapter 13, Chapter 17. Survive on the rooftop

At five o'clock in the afternoon, in the middle of the playground of the Second Research Institute of Sunshine City, the Mi-171 slowly rose into the air, and the huge strong wind brought by the propeller blew over several zombies who had just walked under the helicopter.

Just a few seconds after the helicopter plane took off, a large group of zombies took up the position where the helicopter had been parked just now, and the large group of zombies roared at the helicopter above.

"Oh my God, so many zombies." Fang Wei looked at the group of zombies under the black pressure, and couldn't help but say in a trembling voice.

Suddenly, Lin Xiao saw a zombie flying up below, and she exclaimed, "The zombie was thrown up." ”

Everyone was shocked, and hurriedly threw down the window to look down, and they found that a zombie was thrown up from the zombie group below, but the helicopter rose at a fast speed, and the zombie was thrown into the air more than 20 meters high and fell down, smashing heavily into the zombie group below, crushing a zombie.

"Ouyang, where are they?" Lin Xiao looked down, but she didn't see anyone on the rooftop of the building, there were just dense zombies below, almost filling half of the research institute, she couldn't imagine what would have happened to them if the helicopter had taken off slower just now.

"Company Commander Ouyang said that they would climb to the roof of the test building just now." Fang Wei said.

"I know, but you haven't seen them, you're calling them on the walkie-talkie." Lin Xiao said anxiously.

Fang Wei immediately took out the walkie-talkie and called: "Company Commander Ouyang, we have taken off, where are you, where are you?" ”

Ouyang Hao was standing on the staircase on the fifth floor at this time, shooting fiercely at the bottom of the stairs, he saw through the gap in the stairs that T4 had run to the third floor, so he started to strafe downstairs, and at the same time, Shentu Dina took out three bombs made by Fan Xiang himself from his backpack.

Shentu Dina ran up the steps from the fifth floor to the corner of the sixth floor. A bomb was placed on the steps every few steps, and the bomb was placed in the middle of the steps, and then nodded at Ouyang Hao and said, "Okay, let's go." ”

Ouyang Hao had already emptied two magazines at this time, and his assault rifle still had more than a dozen bullets, and seeing that Shentu Dina had done it, he hurriedly put away his gun and followed Shentu Dina upstairs.

"Roaring ......" T4 downstairs was not suppressed by bullets, and immediately rushed upstairs, and the speed was also very fast, and he rushed to the fourth floor at once.

"Quick. Quick, the monster is catching up. Luo Gang has been looking down from the railing on the sixth floor.

"Quick, all crouch, I'm going to detonate." Shentu Dina shouted loudly with the detonator in her hand.

Ouyang Hao and Luo Gang hurriedly squatted down against the wall, holding their heads with both hands, and Shentu Dina pressed the small red button on the remote control.

"Boom......" There was a loud noise downstairs, Ouyang Hao felt that the floor under his feet was shaking violently, and the wall skin on the top was also shaken off several pieces, and the wall ash fell down. A wave of air mixed with a large amount of dust rushed from below to above.

"Ahem...... cough ......" Luo Gang was choked by the oncoming dust and coughed violently, while Ouyang Hao stood up and walked to the side of the railing. Looking down the stairs, I saw that the section of steps from the fifth floor to the corner of the sixth floor had been blown down.

Shentu Dina looked down from Ouyang Hao's side, and she said lightly: "Okay, blow up half of the stairs." That T4 probably won't come up again. ”

"Probably not, let's go to the rooftop." After Ouyang Hao finished speaking, he turned around and walked towards the stairs above, and above was the door to the rooftop. At the same time, he took out the walkie-talkie and said, "I'm Ouyang Hao, we're going to go to the rooftop now, and we'll receive an invitation." ”

The moment the remote-controlled bomb exploded just now, everyone on the helicopter naturally discovered that Fan Xiang's self-made remote-controlled bomb was very powerful, and the glass windows on the entire fifth floor of the building were shattered together, but everyone on the helicopter didn't know what was going on in the building, just when everyone was guessing and worrying, Fang Wei's walkie-talkie rang again, it was Ouyang Hao calling.

"Received, we are in the sky above the research institute, you guys go to the rooftop, I'll let Han Fei drive over." Fang Wei hurriedly shouted loudly.

"Wait, you see, what's that?" Suddenly, a soldier looked out the window and shouted.

Lin Xiao, Fang Wei and the others hurriedly came to the window of the helicopter and looked down, and several of them saw that on the outer wall of the real building, there were a few things lying on the wall, moving upward.

"Holy, that's Creeper T1." Zhou Tian's eyes were sharp, and he could clearly see that the things that were crawling up on the outer wall of the building were Creeper T1.

"It's really Creeper T1, it's too bad, they actually want to climb onto the rooftop, hurry up and notify Ouyang Hao of them." Lin Xiao said loudly to Fang Wei, and at the same time said to the other soldiers: "We have to attack these things, we can't let them climb up to the rooftop, otherwise Ouyang Hao and they will be in danger." ”

Fang Wei hurriedly took out the walkie-talkie and shouted: "Company Commander Ouyang, there are now several mutated creeper T1s climbing up on the outer wall of the building you are in, you have to pay attention, we will come over immediately." ”

At the same time, one of the fighters opened the door of the helicopter, and the two fighters came to the door of the cabin, raised their assault rifles in their hands, and began to shoot at the creeper T1, which was climbing up the outer wall of the real yàn building in front of them.

"There's creepers coming along the outer wall, be careful." Ouyang Hao said to Luo Gang and Shentu Dina, and then the three of them came to the rooftop of the building, and at a glance they saw the helicopter flying towards this side.

The two fighters on the helicopter kept shooting at the crawler T1 on the outer wall, but the marksmanship of the two fighters was average, and the helicopter shook a little, and there were as many as six or seven T1s climbing up the building, and only two were knocked downstairs by bullets, and the rest were still climbing up quickly, and they would soon climb to the rooftop.

Seeing that the crawler T1 on the outer wall of the building was about to go up to the rooftop, Han Fei also drove the helicopter over, stopped over the rooftop, and lowered the altitude, but he didn't dare to land directly on the rooftop.

"Why don't you land?" Zhou Tian shouted anxiously.

"You can't land, it's too risky, there's a rope in the cabin, throw them down and pull them up, what are you waiting for, hurry up." Han Fei's hoarse voice sounded in the cabin.

Fang Wei hurriedly took the rope from the cabin, locked it next to the cabin door, and then threw the rope down.

The three people below immediately rushed over, Ouyang Hao pulled the rope, and said to Luo Gang and Shentu Dina: "Okay, you two go up first." (To be continued......)
