The two of them went all the way down the dark passage, and from time to time there would be a cool breeze blowing in their faces. In the past, the air circulation at this temperature must be refreshing for people who are tormented by the middle of summer, but at this time it feels eerie. Every corner, every pillar, every shadow that cannot be illuminated by the flashlight, it is as if there are unknown monsters hidden in them, and they will pounce on them at any time and place.

"Bang bang...... Boom Boom Boom ...... ......Suddenly, there was a banging sound in the small door behind the ticket office, followed by two crisp sounds. The gun in Sun Jianjian's hand fired, and the bullets hit the artificial marble walls and fire doors, splashing sparks.

"Brother Sun...... Don't shoot me behind my ear......"

Hong Tao subconsciously raised the shield, in this kind of space is not too big, and it is very uncomfortable and dangerous to shoot in an environment where there are hard objects all around. The uncomfortable thing is that the gunfire is more than twice as loud than usual, which is very harsh. The danger is that the warhead will bounce irregularly, and if it is not in order, it will accidentally injure its own people.

"Whew...... I'm sorry, I'm sorry...... I haven't touched a gun for so many years, and I feel a little vain...... "Sun Jianshe has been a soldier, and he must know these taboos." But he couldn't control the tension of his body and mind, and the two shots just now were not targets at all, but shadows reflected by the flashlight.

“…… You'd better hang up the insurance, I guess only this door has zombies in it, and you won't need bullets to hit them! Hong Tao didn't complain about Sun Jianjian, and he would feel helpless when there was nothing in the dark underground space.

Squatting on the ground and listening carefully for a while, except for the sound of the impact in the fire door next to it, there was no other sound, and it was estimated that there would not be so many people on the night shift at a platform, just killed four, and then two or three will be over.

There is no need to violently break the fire door when you open the fire door, Hong Tao found two sets of keys from the four zombies above, and at first glance it was not at home, so he tried them one by one, and it worked.

But after the fire door was opened, no zombies immediately rushed out, and the guy in the security uniform inside did not knock on the fire door, but banged on another door at the end of the corridor.

"Just one?" Without waiting for the zombie to approach, Sun Jianshe gave it a slap in the head, and then sighed unsatisfactorily.

"Bang bang...... Hey, is there anyone in there? We are living people, not monsters......"

Hong Tao's attention was not on the zombie, and when he opened the fire door, he noticed the abnormality of the zombie, and the flashlight kept aiming at the door at the end of the corridor. Now that the zombie is dead, he simply knocks on the door with a pickaxe and shouts inside.

"Click...... "No one answered, but there was a slight metal crash............ It's just that the source is too weird, it's actually overhead!

"Stand back!" Hong Tao felt like he had been electrocuted, and the hairs on his body exploded. At this time, he thought of the scene in the movie Alien, where the monster's hiding place was the ventilation pipe, from where it would come out and raid the crew of the spaceship, one after another!

"It's—it's on it!?" Sun Jianshe probably hadn't seen this movie, but he had already read it from Hong Tao's expression and eyes, and immediately raised the fire hook in his hand, and the flashlight also shone on the ceiling.

"We're on the big deal...... Don't make a sound...... Slowly retreat out the door...... Listen to my command and run together......" Hong Tao also raised his shield, stunned his ears, and tiptoed towards the fire door. The movements were so supple and funny to the extreme, as if they were doing a very weird dance.

"Click...... Whoa...... Squeaky ...... Ahem......" Suddenly the sound reappeared, but this time there were many more bits and pieces, as if something had fallen in the ventilation pipe, and it kept rolling, and it stopped after a few seconds, followed by two soft coughs.

“…… Brother Sun, have you ever heard a zombie cough? Hong Tao stopped his body movements, one leg was hanging in the air and he didn't dare to land, but his mouth was not idle, and he asked Sun Jianshe in a low voice.

"It doesn't seem to be ...... Could it be a human being? "Sun Jianshe has been cleaning up the courtyard with the team these days, and the zombies killed are no less than Hong Tao, and I have never heard of zombies coughing. In fact, these monsters who are not human or ghostly do not make any sound, and they don't even breathe, but they are quiet.

Hong Tao also thinks so, and if you think about it carefully, zombies can't climb over the wall, how can they get into the ventilation pipe. Even if it happens to mutate in the ventilation pipe, so many days have passed, and there is no sun at all, and the power should be almost out of power. Considering the state of early summer, the answer is obvious.

“…… It should be here, poke the roof open! "If it's not a zombie, it's just a person or an animal. No matter what it is, these two things are not very afraid of Hong Tao anyway, and they must be opened to see and figure it out.

"Whoa...... "This fire hook is useful, it was originally used to demolish the interior of the building, and it is much faster to poke off the ceiling than to kill zombies."......

"Ahem...... Don't shoot...... I'm an employee here...... cough cough cough ......"

Not long after, the flashlight found a shadow in the exhaust vent of the ventilation pipe, and it was impossible to tell what shape it was, but the intermittent light cough and the Chinese with a gossamer had clearly indicated her identity. That's right, it's her, it's a woman's voice.

"Then what are you running! Didn't I just shout, why didn't I answer! Hong Tao asked Sun Jianshe to take a flashlight to look around, and he himself stood under the vent and held a shield to continue the interrogation. Even people can't be too careless, and the lesson of carelessness at the police station last time is deep enough.

"I—I'm afraid...... They've been chasing me...... And bit my colleague to death...... Woo-woo-woo......" There was a whimper from the vent.

"You're an employee here? Guard's? Hong Tao rolled his eyes and threw out a more professional question.

"It's not...... I'm a ...... from the Mechatronics Group I came here last Friday to overhaul the No. 8 fan, but it had an accident before I got off work...... I watched my colleague in the locker room through the window being bitten by the guards, and then ...... And then it turned into a monster...... Woowoo...... I don't know what to do...... Woo woo woo ...... "The woman in the ventilation pipe was a little louder, but it sounded so weak that she couldn't finish a sentence.

"Then what have you eaten and drunk for so many days!" The general situation that the woman said was strung together, and now there is still the most important question that needs to be clarified.

"There were a few packets of chips, instant noodles, and bottled water in the locker...... Are you really not monsters? The woman in the ventilation pipe didn't quite believe Hong Tao either, she was slowly squirming all the time, and she was already a meter away when she spoke.

"Can the monster talk to you? Don't climb yet, if I try to hurt you, this thin layer of iron won't stop the bullet at all. Hurry up and find a place to see what I look like, come down when you are relieved, and continue to eat your snacks if you are not at ease, I will not force it! ”

By this time, Hong Tao had basically determined that the person hiding in the ventilation pipe was a normal person, and there was no conspiracy, and his nervous mood relaxed, and joy arose. It's not a loss to come out this time, I have found out the underground fortifications with great development prospects, and I can also save three big living people with my hands!

"Come, look carefully, standard Chinese beautiful man...... Good health and complete limbs! The woman in the ventilation pipe seemed to have crawled back again, and Hong Tao quickly took off the helmet and took a photometer with a flashlight, trying to beautify himself better.

“…… I went down from the locker room ......" The effect was not bad, the woman in the ventilation pipe did not continue to doubt Hong Tao's identity, at least admitted that he was a person, and immediately took action, crawling along the ventilation pipe to the room at the end of the corridor.

This room is supposed to be the changing room of the subway station employees, and there are two rows of lockers against the wall, the ceiling above the cabinet is opened, there is a ventilation opening, and a chair is placed next to the cabinet.

Obviously, this woman climbed to the top of the cabinet first, then opened the vent and got into the ventilation duct, and used it as a hiding place to stay in it for ten days! It's not right, she should have run back halfway, and she could take all the snacks with her, but she couldn't take this bucket of water with her, so she could only come back regularly.
