Help me...... Help me...... We are in the basement of Building 2...... The voice was intermittent, but Yu Changsheng still felt very excited, it seemed that it was really as he expected, there were still survivors here.

Without further ado, Yu Changsheng immediately came out of the communication room and returned to the window.

But it's not easy to jump in, and it's a problem to get down from here. Just as he was thinking, he found that Wang Houxiong had dragged a large training mat from the treasury. At the critical moment, this big guy is still a little wise.

Yu Changsheng jumped down, and although he was supported by a mat, he still fell in pain.

"How?" Wang Houxiong asked.

"They were in the basement of Building 2, it was a woman's voice." Yu Changsheng said.

"A woman's voice? Hehe, that's pretty good, I haven't seen a woman in a long time......" Wang Houxiong suddenly laughed.

"Cut...... Even if it's a woman, it seems that your body doesn't have enough energy to do anything. Yu Changsheng couldn't help but say.

"Then you are wrong, now I, don't look at the crooked nose, the place that should be hard and ......long is harder and longer than the original," Wang Houxiong retorted.

"Okay, okay, stop it, I'm not interested in this." Yu Changsheng waved his hand helplessly.

But at this moment, Yu Changsheng suddenly realized that something was not quite right, and the woman's cry for help ...... Why a woman? Could it be that there are only a few women left among the survivors? If that's not the case, then why not choose a more negotiating man for help? In a normal critical situation, when men and women coexist, women tend to instinctively rely more on men.

"What's wrong? Why don't you go in a daze, it's going to be dark. Wang Houxiong urged.

"Nothing." Yu Changsheng replied absentmindedly.

The two continued to walk forward, and soon found Building No. 2, and Yu Changsheng noticed that the location of Building No. 2 was indeed very hidden, and it was relatively complete compared to other collapsed buildings. What's more, the underground ventilation system outside the building is still well preserved, and if every building in the camp had a basement, the basement of this building would undoubtedly be safer and more durable.

The two entered the building one after the other, compared to the mess and cruelty of the other buildings, the second building was unusually tidy, the entire first floor was obviously cleaned, there was not a single body in sight, and there were several obvious drag marks on the ground, apparently left by the survivors inside when they dragged supplies from the warehouse. Yu Changsheng speculated that the space in this basement was at least three hundred square meters, and there were at least ten survivors.

The deeper Yu Changsheng went, the more obvious the marks left on the ground became, and even some flour would be left as a guide every once in a while. Yu Changsheng knew very well that such traces, with the IQ of those monsters, were not enough to judge the location of the survivors, because they could only follow the scent. But if an ordinary person accidentally enters the ruins, it is likely that the survivors may be able to determine the location of the survivors through these traces.

But anyway, if you think about it from another perspective, Yu Changsheng still feels that if he is one of the survivors, he still won't leave such a clue, and what's even weirder is that it is also the most puzzling point of Yu Changsheng.

What are these survivors waiting for in the destroyed base, in danger of the resurgence of those two terrible monsters? Why not try to escape?

All of this may only be answered when the survivors are found.

The flashlight flickered in the empty corridor, Yu Changsheng faintly felt a bad premonition, he made a gesture behind him, and whispered to the queen behind him:

"Be careful, there may be traps here."

"Oh? Pitfall? Do these guys think monsters are afraid of traps? The queen didn't care.

"Why against monsters? I don't think these guys really want us to rescue them, but ...... Took us for prey. Yu Changsheng muttered.

"Huh? Why? Are these guys deliberately luring you here and taking away your supplies? This doesn't make sense, I'm afraid the supplies here are enough for a hundred people to support a year. The queen was surprised.

In fact, this is also what Yu Changsheng thinks is the most unreasonable, but judging from these traces on the ground and the woman's cries for help before, he always feels that this is a trap, as if someone deliberately lured him forward.

"Just follow me, just be careful." Yu Changsheng said solemnly, took out the gas mask from his backpack and put it on his face.

Queen Xiong answered, although he didn't know the origin of Yu Changsheng's guess, he was not afraid of any traps.

Yu Changsheng continued to walk along the flour, and soon came to a locked room on the first floor, the room was a combination lock, there was no other entrance, if the guidance of those flours was correct, then this should be the entrance to the basement. Wearing a gas mask and helmet at the same time, it made Yu Changsheng's movement a little inconvenient, but even though the corpse on the first floor had been removed, the building was still filled with a suffocating stench.

"Look, there are no traps here, the door is locked, and the flour must have been accidentally left behind by them while dragging supplies." Wang Houxiong said.

Yu Changsheng immediately shook his head and said with great certainty:

"No, in the current situation, all kinds of resources are very scarce, and no one will choose flour as a food reserve, because to process flour into edible food, it needs to consume a lot of water and other materials, and these flours must be left on purpose."

Wang Houxiong scratched his head, thinking about it too.

"So what are you going to do? This kind of password door is not easy to crack. ”

Yu Changsheng looked at the door and tried to enter some simple passwords, because if these doors are simply used to block monsters, then there is no need for complicated passwords at all, because most of these monsters can only use brute force, even if some monsters have a higher IQ, but they are only fighting and hunting IQ, and it is impossible to have this kind of life skill of entering passwords.

Sure enough, as Yu Changsheng expected, after he entered some simple passwords, he quickly opened the password door, and the password of the password door was 987654321, which confirmed his idea even more, even if it was impossible for monsters to crack the password door, but according to the habits of normal people, they would still instinctively think that it was more secure to enter some complex passwords. And the survivors inside deliberately changed the password to such a simple password, there must be something wrong with this!

Yu Changsheng held the handle of the door, looked around, Yu Changsheng found that he was now in the corridor, there was no video surveillance like other buildings, which was even more strange, the original monitoring position left a gap, the bracket for hanging monitoring was still there, but the monitoring inside was gone, which was obviously not caused by the vibration when the building was damaged.

Someone must have switched the camera position and was able to secretly monitor the door.

Yu Changsheng did not open the door immediately, but whispered to Wang Houxiong:

"You step back a bit."

The queen did so, and Yu Changsheng also bowed slightly, his face shifted to the side of his body, and then half of his body was facing the door, slowly pulling the handle, and then pulling the code door outward.

The password door creaked open, and almost at the same time, a sizzling sound suddenly sounded, everything happened too fast, and before Yu Changsheng could see what was happening, he found that his eyes were immediately shrouded in a thick fog, and the water vapor in the room rose, I don't know what valve was suddenly opened, and a scorching gas suddenly filled the entire room, and continued to spread outward.

Yu Changsheng quickly retreated outside the door, Wang Houxiong was far away from the password, and he was not harmed, although this gas was scorching, it looked like it was just ordinary water vapor, and it seemed to be non-toxic. For the sake of prudence, Yu Changsheng still confirmed with Wang Houxiong:

"You come closer, help me see if it's just moisture."

Wang Houxiong looked reluctant and complained:

"Although I can eat carrion, it doesn't mean that I am invincible."

Despite this, Wang Houxiong tried to get close to the gas, but he soon discovered that the water vapor was indeed just ordinary water vapor, and the gas in the room was still spreading, and the temperature in the room was also rising.

"Well, these should be ordinary steam, and I seem to see the valves." Wang Houxiong said.

Yu Changsheng opened the gas mask slightly, and found that the smell was indeed just the smell of ordinary water vapor. But since these are just ordinary water vapors, why did they suddenly appear here, and could it be said that these water vapors also have a defensive function?

Wang Houxiong fumbled to the valve next to the door, but he found that the valve was connected to the inner handle of the code door with a wire wire, as long as the person outside opened the code door, the valve would be opened, and the screws on it would also trip. As a result, the valve will not be able to be closed.

"No, the valve is tripped, and it can't be closed." Wang Houxiong said.

Yu Changsheng strengthened the flashlight, and the flashlight formed a clear pillar of light in the mist, although these mist became more and more, but the room did not change except that it became a little stuffy, as if entering a steam room. The room inside this password door is larger than Yu Changsheng imagined, and it seems that it should have been originally used for scientific research. Yu Changsheng and Wang Houxiong entered the room and began to search inside, Yu Changsheng took off the gas mask, this kind of gas mask without connecting to the air breath is difficult to breathe in such a high temperature and low pressure situation.

There were all kinds of unknown instruments in the room, as well as bottles and cans, but there were no other clues to the basement, and just when the two of them were at a loss, Yu Changsheng suddenly heard a sudden clicking sound at the entrance.

The code door was actually shut!

"Not good!" Yu Changsheng exclaimed, and suddenly felt that the air between his snorts had changed without noticing.

He felt everything in front of him become dizzy, the queen's huge black shadow became distorted, and the steam in this room suddenly had a slightly sweet pungent smell at some point.

It was at this moment that Yu Changsheng suddenly understood that the steam in the room before was to increase the temperature and air pressure here, so that the people who entered this room had to take off their gas masks, so that if they injected poisonous gas into the room, the people in the room would be defenseless.

And this slightly sweet, pungent smell...... It should be Yimi!
