With 30 percent of the distance left, it took only 3 minutes for the group to climb through.

Liang Yi was almost dragging Luo Guangcheng to climb, this old guy didn't look lean, the weight was not light.

"Go up, you go up first!" He sent Luo Guangcheng up the stairs first.

"No, no, No, Chief Liang, you're not right, how can I take the lead, I'......" Luo Guangcheng shook his head like a rattle.

"Then you'll be back!"

Liang Yi was about to pull Luo Guangcheng down, the old man thought about it, wouldn't it be more unlucky to be behind the mat, and chattered: "Then I'd better go up first," After speaking, he didn't need Liang Yi to help push it, and he touched the ladder to climb up.

"Hurry up, too!"

Liang Yisha was in the corner at the end, and after sending everyone up the ladder, the roar under the pipe became more and more intense, "Knock knock!" "Violent vibrations, warning that behemoths are about to appear!

"Damn, hurry up, Chief Liang is still down there!"

The passage is so narrow, one can't walk, and the back has to be blocked, Ye Qiu scolded while squeezing up, wanting to make room for Liang Yi to rise.

"Professor Luo, don't stop, there are still people down there who haven't come up!"

"I ...... Alas, I can't crawl, I really can't crawl......"

"Fuck, damn old man, you TM did it on purpose!"

“Duang，Duang，Duang！”

The ceiling was violently hammered, and the infected also took a ladder to show their heads at the air supply vent, and it would not be more than a few minutes to climb up the pipe!

Liang Yi and Gu Yicheng, who fell last, have seen the world after all, and they should be calm in the face of emergencies, and tacitly take out sharp weapons with each other, ready to meet the attack of the berserker at any time!

"You shouldn't let Professor Luo take the lead, he's a notoriously small-bellied chicken intestine." Gu Yicheng said softly.

Liang Yi finally had the opportunity to face Gu Yicheng face to face, and said with a sharp gaze: "You don't know about the Zerg, so do you know about the night ghost?" ”

"I don't know." Gu Yicheng shook his head, his expression firm and unquestionable.

"Then let me tell you that this plague is spread through the night ghosts, and the source of the X virus is from your laboratory, in the final analysis, the simplest relationship is between you and the night ghosts, it is impossible to be unintentional!"

Liang Yi pointed at Gu Yicheng's nose and blamed him!

、

Gu Yicheng seemed to be angry, opened Liang Yi's hand, and said angrily: "Do you doubt me? ”

Liang Yi said coldly: "The person who knows the most should be suspected!" ”

"Then if you want to say that, I can't help it, anyway, I don't know anything, how you like to say it, I'm just a brick, the country can take it, the organization can take it, OK...... I don't have personal freedom, so let's see which country or organization is more capable of snatching my brick! ”

Gu Yicheng smiled coldly, shrugged his shoulders, looked like he loved everything, and he was not angry with Liang Yi, nor did he open his mouth anymore.

"Roar!"

The berserker has come up from the major air outlets, Liang Yi pulled out the pistol on his waist, and a bullet killed the nearest one first, and the passage was so narrow, no matter how the berserker behind squeezed, he had to be gambled by the corpse!

The most feared is the giant berserker that pounds the ceiling, powerful enough to unload the entire ventilation duct.

"Old man, if Lao Tzu goes out and doesn't reward you for two ear scrapers, Lao Tzu's name will be read upside down!"

Ye Qiu's threat of force finally worked, and Old Man Luo estimated that he had enough revenge, and the team blocking the stairs finally loosened a little.

"Come up."

Gu Yicheng clenched Liang Yi's hand and pulled him up to the ladder connecting the mouth, and at this time, the giant berserker also began to disassemble the pipe hidden in the ceiling - "Boom! There was a violent collapse sound, and the stainless steel pipe seemed to be "cramped", and all the infected people in the pipe were pulled out!

After the pipe was withdrawn, the connecting staircase was exposed in the corridor on the first floor, and Liang Yi's hind feet had just retracted into the ventilation pipe on the second floor, and a bloody human head was thrown up from the corridor on the first floor.

"I'll give you one back."

Liang Yi lit a burn. The flask was dropped down the stairs - "Smack! "Burn. The flask smashed, "Boom! "A blazing fire went straight up, and the high concentration of alcohol was enough for the giant monster to drink a pot!

"Spiders, so many spiders!" Suddenly, Luo Guangcheng's shout came from the front, "Hurry, climb back!" ”

"Crawl a chicken feather, Tang Tian, I suggest you kill your teacher, and then block those spiders, otherwise the spiders will turn over his body, and the next one will bite you." Spiders are very venomous, and if you bite it, you will die within 2 minutes! Ye Qiu pulled Song Yinyin forward and proposed in a cold voice.

Tang Tian swallowed his saliva, and really showed a righteous appearance of killing his relatives, looked back at Luo Guangcheng, who was desperately crawling backwards, and said in a serious tone: "Teacher, otherwise you will sacrifice your life to take righteousness, right?" ”

"Bunny, I've been taking you for so many years! Hurry up and climb forward! You're going to kill me! Luo Guangcheng scolded.

The poisonous spiders should have come up from the G3 ventilation pipe, perhaps because Liang Yi slaughtered the mother, and they "squeaked" and raged as soon as they saw humans, and thousands of spiders, like black water, swept in against the pipes.

The second floor couldn't get through, so Liang Yi had to beckon everyone to climb up the connecting ladder!

Facts have proved that human beings can always break out of their physical limits when they encounter danger, not to mention Liang Yi and a few other strong men, Tang Tian and Luo Guangcheng climbed fast, and they did not fall behind Liang Yi at all.

"This bad old man, why didn't you see such a good thing just now?" Ye Qiu scolded.

On the 3rd floor, less than 20m away from the right side, there is a natural vent with 3 fan blades, which rotate clockwise, proving that the wind is blowing outside.

"I've found the exit, everyone come with me!"

Liang Yi turned around, aimed his foot to the right, stretched his arm and retracted it, and when he reached the vent, he kicked the spinning fan out!

"Be careful, there may not be a place to stay outside, slow down." Gu Yicheng reminded behind him.

Liang Yi knew it in his heart, supported the circular pipe with both palms, his feet first penetrated the vent, and shrank down little by little, Gu Yicheng grabbed his shirt behind him and put it little by little.

Liang Yi completely hung on the vent, and hurriedly looked for a foothold left and right, and it happened that there was a cornice about 20cm wide under the ventilation duct, which was more than enough to settle!

"There's a head, come down."

"Boom!"

Liang Yi inserted the sword into the wall, stepped on the hilt of the sword with one foot, stepped on the edge of the eaves with the other, and the horse walked steadily, and the lower plate was as steady as a pine tree, and then began to connect people out in turn.

"If it were Liu Liang and Xu Zhelai, they would definitely not be able to play such a difficult action." Gu Yicheng praised as he moved out of the edge.

Liang Yi said: "They have self-knowledge, and I hope you also have self-knowledge." ”

"Sir Liang, I don't have self-knowledge, can you hug me!" Ye Qiu was startled as soon as he showed his head, and reached out to ask for a hug.

"Think about swinging in the sky, and you will feel that it is pediatrics now, and you will not be afraid." Liang Yi took Ye Qiu's hands and lifted them out with his arms.

Ye Qiu settled well, and he also learned from Liang Yi's example, found a crack on the eaves, wiped the saber and kitchen knife into it, and made two pedals. Of course, this is not for himself.

"Miss Song, come to me!"

It turned out to be reserved for Song Yinyin.

"Ye Ye Ye ...... Officer, it's too high, I'm ...... I don't dare! Song Yinyin was so frightened that she trembled, how could the 3rd floor be 15m from the ground, normal people would feel scared.

"It's okay, I'll hold you tight."

Ye Qiu stood on tiptoe, regardless of whether Song Yinyin agreed or not, and dragged down hard:

"Don't!"

"Shhhh

When Song Yinyin opened her eyes, her feet were already firmly on the saber and kitchen knife, and Ye Qiu also hugged her very tightly.

"Thank you, Officer Ye."

Song Yinyin is a pure woman, such an ambiguous posture, such a close hug, she is also a little unaccustomed, but she never dares to let go.

Ye Qiu moved his hand a little under Song Yinyin's waist again, holding it tighter on the surface, secretly wanting to eat tofu, on the surface, the righteousness lasts forever, and the tone is natural: "It's nothing, I'm the people's police!" ”

"Ye Qiu, don't be me, come and help, there are still two people who haven't come out." Liang Yi urged coldly.

Ye Qiu squeezed his eyebrows and said, "Are there two other people?" I don't know, oops, it's the same whether to save or not, they don't dare to show their heads when I pack the ticket. ”

Song Yinyin urged: "Officer Ye, please help, the research materials are all on Professor Luo and Assistant Professor Tang, and they can't be lost." ”

"But look at them, the shrunken turtle is obvious!"

Ye Qiu pointed to Tang Tian, who was cowering at the vent, stretched out his head to look at the sky, and then retracted, stretched out his head, retracted, one in and one out, like a turtle turtle ...... Head!

"Hurry down, don't be embarrassed!" Liang Yi's temper was good enough, but watching the time pass little by little, Tang Tian's cowardly appearance, anger gradually rose in his heart!

"Old ...... Teacher, will you go down first? Tang Tian turned his head and finished speaking, Luo Guangcheng pushed him out of the vent, "Rabbit cub, you are still grinding at this time, you want to kill me!" ”

"Help!"

"Save your mom and sell batches!"

Ye Qiu and Liang Yi grabbed one of Tang Tian's hands and suspended him in the air.

"Don't let go, don't let go!" Tang Tian kicked his legs, and his voice changed in fright.

"Turtle son, you can't pee your pants, do you? Also tm leg kicks! ”

Ye Qiu and Liang Yi winked at each other. Liang Yi gently sent Tang Tian away, Ye Qiu grabbed Tang Tian's backpack, pressed it against the wall, and said, "Stick tight, shake your legs again, you will die!" ”

Tang Tian was straightened, the big eight characters were pasted on the wall, and tears flowed out.

"Should I really find a nail and nail it into the wall?" Ye Qiu withdrew his hand and continued to hold on to Song Yinyin, no longer caring about Tang Tian's life or death.

There was one last old man left.

The old man was very brave, he climbed such a long distance, and jumped out of the vent without blinking his eyes!

Liang Yi intercepted Luo Guangcheng in the air, grabbed his neckline, and pressed his backhand against the wall: "Stand against the eaves!" ”

"Molotov cocktails!"

Gu Yicheng lit the good light. Burn the bomb bottle to Liang Yi, Liang Yi didn't say a word, and smashed it directly into the vent!

"Smack!" The bottle shatters, and sparks fly!

"Crackling!"

Spider popping, crunching!
