The system is the king of the counterattack master

"A door again? It's so scary! Who are you scaring?" Duan Muxiu's flashlight shook in front of the iron door a few times, and he couldn't help complaining: "Didn't the person in charge of this group of devils take a kickback for making the door?" Is it interesting that there are doors everywhere?"

Han Xiaodong approached the door and took a look. Before that line of writing, he rubbed vigorously a few times, revealing the entire sentence in Japanese:

Staff below the fourth level are forbidden to enter, and those who get started will die!

The three people looked at each other when they saw the words on it. The words were not written for them, but for the Japanese themselves.

They have seen this kind of warning before, except for some identity, it is forbidden to enter, but it is usually followed by a sentence at your own risk, directly saying that the beginner is dead, this is the first time.

"This is a bit interesting. Do you remember those files we saw? I remember that the highest level of staff seems to be the third level, right?" Duan Muxiu looked at the line and said puzzled.

"That's right, it means that there are still people in the building who are not on the register. I don't know about others, but that Dr. Matsumoto must be one of them." Han Xiaodong took off the sprayer on his back, picked up a flashlight and looked around the environment.

Suddenly, the beam of his flashlight stopped in front of a valve. He walked over and turned it around, and found that the valve was loose. He followed the pipes where the valves were located to find the source, and found that the pipes had finally sunk into the wall.

He thought for a while, and then said to He Xi and Duan Muxiu: "It seems that the poisonous gas that harmed us came from here, and the person who released the poisonous gas is not generally familiar with this place."

Han Xiaodong deliberately did not say who released the poisonous gas. In fact, everyone knew that if it was Zhou Hao who released the poisonous gas, then Xueqing would definitely die before them. From this, it is not difficult to deduce that the person who released the poisonous gas must be Xueqing.

"Never mind him, let's go in and have a look, the ghost knows there are other messy things in here, you have to be careful this time." Duan Muxiu said, touching the gun on his back, although he knew that they met today. What you get can't be solved with a gun, but there is a guy who can always be brave.

Han Xiaodong pushed the iron door lightly, but found that it couldn't be pushed. After a closer look, he found that it was a sliding door.He asked Duan Muxiu and He Xi to stand back first, and he pulled hard, and the door creaked open.

Perhaps it was because they felt that they couldn't survive the attack of the black air, Xueqing didn't lock the door inside, but let it close like that, just to prevent the black air from running in.

Inside the door is no longer a huge space, but a long corridor. To the surprise of the trio, there seems to be a bright light at the end of the corridor.

"Is there a light? Could there be someone at the end of the corridor?" Duan Muxiu looked at the light and lowered his voice several levels.

"Guess it's Zhou Hao or Xue Qing. Let's bet on tomorrow's breakfast." He Xi looked at the bright spot and asked through the intercom.

"I don't think so." Han Xiaodong replied casually, holding a flashlight and entering the corridor.

The corridor was very long, and the three of them walked for about a minute before reaching the front of the bright light. When they looked down, it turned out to be a mobile phone!
"This is Xueqing's!" Duanmuxiu was the first to recognize the owner of this phone.

The phone's screen was always on, which meant that it was not set to a timed lock screen, so the phone was naturally unlocked. Han Xiaodong looked at it and found that Xueqing had indeed set it to airplane mode, so it was impossible to get through.

He flipped through the contents of the phone, but found nothing special, all the contents were normal, it was just an ordinary girl's phone.

Looking at the cell phone that was thrown at the door, Han Xiaodong was puzzled. It is said that this kind of personal item is not needed temporarily, so it should not be thrown here casually. What is the reason for this?Could it be that Xueqing encountered some accident?Or was she staying here on purpose to leave a message for them?
Unable to figure out the reason behind it, Han Xiaodong simply turned off his cell phone and was about to open another door at the end of the corridor. As long as he opened this door, all the mysteries might be solved.

Same as the door outside, this is still a sliding door, Han Xiaodong still let Duanmuxiu and He Xi back, moved his body a bit, and was about to pull the iron door open, just when his hand just reached the doorknob, Suddenly there was a piercing sound behind him!

Han Xiaodong was startled, and quickly turned around to look. The voice came from Xueqing's mobile phone in He Xi's hand!

This sound is very strange, it sounds like white noise, but it is sharper than white noise, like someone scratching the glass with their fingers, or like the screams of countless people piercing their hearts.

"What?" Han Xiaodong quickly walked up to He Xi.

He Xi frantically pressed the button, and finally made the voice stop.

"It's an alarm." He Xi stood up the phone and showed the interface to Han Xiaodong.

Duan Muxiu was obviously frightened by the sudden sound, and when He Xi said it was an alarm, she also moved her head to look at the phone's interface.

I saw that the mobile phone was densely set with ringtones, ringing every 10 minutes, from two and a half hours ago to [-]:[-] tomorrow morning!
"Xueqing went in two and a half hours earlier than us." Han Xiaodong said while looking at the phone's alarm interface.He really couldn't figure out the meaning of the alarm. No one would set the ringtone in the middle of the night. Even if there was some special reason, the sound would be too weird. If you let this ringtone wake you up in the morning, it might not scare you. Almost crazy.

He took the mobile phone and operated it, and finally called up the music file of the custom ringtone, which was written in Chinese pinyin: yinluling.
"Guiding bell?" Duanmuxiu spelled out the meaning in pinyin: "What way to lead? What way to lead? Why lead the way? Who will lead the way?"

This series of questions were asked like Bengdou, almost comparable to the classic "Who am I? Where am I? What am I going to do?".

Han Xiaodong looked at the file name, thought for a while, and couldn't figure out what he meant, but at least he knew that Xueqing didn't drop the phone here because of any accident, on the contrary, she did it on purpose. There must be some specific purpose.

Looking at the iron gate, a thought suddenly appeared in Han Xiaodong's mind, and at the same time he pressed it lightly, and the eerie bell rang again.

Different from just now, the ringing of the bell this time was done on purpose by Han Xiaodong. He just wanted to see what the ringing sound was for.It's better to figure things out here, and it's better to get blind after going in.

Since Xueqing was able to put her phone outside, it meant that the target she wanted to guide must be nearby, or more precisely, behind the door.

The alarm rang for a while, but there was no movement, because Duanmuxiu thought it was too scary to have such a sound in this empty corridor, so Duanmuxiu snatched the phone and stopped the ringing.

"I think it's just to scare people. Let's go in. She has left us for more than two hours. I don't know what will happen inside." Duanmuxiu reached out to pull the iron door after finishing speaking.

Just as his hand touched the handle of the iron door, there was a loud bang suddenly from the other side of the iron door.
