The villain is trapped in the system and begs me to let him out [Moriarty who worries about the coun

"clatter……"

"clatter……"

"clatter……"

Late at night, in an inconspicuous corner of the medical laboratory building, only the crisp sound of stepping on the steel ladder echoed quietly in the air.

"Tell me," Du Ruoying asked softly while crawling down, "While talking about the combustion chamber, Bai Qirun has already replaced William?"

"Yes." Du Ruoxian reached the bottom of the well first, and then caught Du Ruoying.

The two continued to walk deeper into the corridor.

"That means he's been eavesdropping on our conversation," she said to herself.

For some reason, I always feel that there seems to be something wrong, like——although I hold the correct pieces, but I don’t know the so-called puzzle.

A strong sense of foreboding suddenly surfaced.

The white light of the flashlight passed by an iron gate next to it, illuminating the old signboard on the forehead. The once white color has now turned a little yellowish, and three long and thin red imitation Song characters can be vaguely seen on it——

"Combustion chamber".

Du Ruoying was stunned: "No, it's not just eavesdropping, he already knew about the existence of this underground boiler room...how could this be?"

"Maybe he came here earlier with the professor." Du Ruoxian said calmly.

"There will be such a coincidence?" Du Ruoying thought, "Or, they got the coordinates in advance—" Just as they were speaking, a cold white mist suddenly sprayed out from both sides of the corridor, interrupting their conversation. Suddenly, the white mist spread rapidly, soon filling the entire space.

Oops, there is a trap!

Du Ruoying subconsciously covered her mouth and nose tightly, but she still accidentally inhaled a lot.

Subconsciously, she leaned towards Du Ruoxian, only to find that he was so calm that it was abnormal—not only did he not hold back his breathing, but he also went straight to the hidden vent.

He reached out and touched the edge of the vent, and became more convinced of his guess: "Don't panic, it's dry ice gas."

"Huh?!" Du Ruoying followed suspiciously, seeing the tiny drops of water on his fingertips, "Well, it really is... so what is the murderer trying to do? Create a stage atmosphere?"

here we go again……

Misplaced leads, incomprehensible status quo.

Everything is so abnormal.

Like an abnormal spider's web, every string is put in the wrong place, and the prey is about to break free.It is also like the spider behind the scenes deliberately playing the game of playing hard to get, carelessly fooling their group of prey who have entered the web.

It's really uncomfortable, this feeling...

what is the problem?

Du Ruoxian didn't answer her question, he continued to walk forward silently, the cold light of the flashlight followed the shoe prints on the thin dust, they were William's shoe prints, a string of lonely ones, leading directly to the iron door of the boiler room .

William is clearly in here.

Du Ruoxian stretched out his hand and tugged at the door, but the iron door didn't move at all. Through the crack of the door, one could vaguely see a finger-thick iron bolt running across it—the door was locked from the inside, and it was locked firmly.

"Look around to see if there are any tools that can be used to break the door."

Du Ruoying noticed the police gun hidden at his waist: "How about breaking the lock with a gun?"

"No, the space here is too narrow, and the iron gate is also very strong. Bullets will ricochet when hitting it, and it is easy to hurt yourself."

Suddenly, a small ball at his feet caught Du Ruoxian's attention. He picked it up and saw that it was a dirty metal casting, about the size of a fist, but very light in weight.

"Yes, there is no need to look for it."

"What's this? Water pipe parts?" Du Ruoying asked suspiciously.

"Maybe," Du Ruoxian said, "It doesn't matter, as long as it's an aluminum product."

He took out a small knife, scraped off the dirt on the surface of the casting, and then ground a layer of pure silver-gray powder, and picked up a pinch with the tip of the knife.

Through the crack of the door, he dipped the powder onto the heavy iron latch.

"Stay farther away, it's a bit dangerous." Du Ruoxian took out a lighter, "It's best to cover your eyes too."

Until then, Du Ruoying finally understood what he was going to do——

It's the thermite reaction!

This is a redox reaction that uses aluminum powder as a reactant to reduce iron oxide to iron. The reaction process is rapid and violent, and the high heat released can reach two to three thousand degrees Celsius, which is enough to melt metal and can be used for metal welding. Naturally, it is not a problem to fuse the iron door components. [1]

After realizing this, Du Ruoying immediately closed her eyes tightly.

The moment the flame on the note touched the aluminum powder, dazzling electric sparks splashed out from the crack of the bolt, and with chilling heat, it quickly melted a hole in the iron door.

Du Ruoying didn't open her eyes until the fire was extinguished and the surroundings fell into darkness again.

The dizziness caused by the previous strong light had not dissipated, she rubbed her eyes, trying to refocus.With the pale and dim light of the flashlight, she found that the bolt behind the door had already been fused into two pieces.

Du Ruoxian easily kicked the iron gate open.

The two came to this empty boiler room. In front of them, the door of the huge boiler was half open. The white mist in the cavity had not yet dissipated, and there were still a few wisps floating low in the air.

Taking a closer look, it is not difficult to find that the main component of the white mist is also dry ice gas.

Looking at the messy drag marks on the ground, Du Ruoxian showed a clear expression: "The murderer had indeed prepared hypnosis gas, but the professor and Qi Run came here in advance to make a replacement, replacing the gas with similar-looking dry ice gas. Then, here, the professor pretends to fall into the trap of the murderer, passes out, and is taken away by the murderer."

"Bingo!" Bai Qirun's happy voice came from Du Ruoying's cell phone.

Du Ruoying: ...? ! !

"Didn't I hang up on you already?"

"It's just that you think you're dead, you're so stupid," Bai Qirun laughed, "Could it be that you think what you think is really what you think?"

Emmm...

Du Ruoying resisted the urge to fight back, and asked in a low voice, "That's right, tell us, what exactly is William's plan?"

"I don't know, he didn't tell me." Bai Qirun said frankly, "I only know that he locked the boiler room a long time ago - he asked me to check the task sheet of the missing cleaning staff. The mission was this medical laboratory building. Then we walked around together and found this place.

"There are many organs in this underground secret room. It is easy for ordinary people to get into trouble. I guess Auntie Cleaning suffered such a tragic accident. But these organs are trivial to me. Just a few clicks will destroy them all-but, according to Brother Lian requirements, I still let them maintain the illusion of normal operation."

"Sure enough." Du Ruoxian frowned.

"So you replaced the hypnotic gas with dry ice gas?" Du Ruoying asked.

"That's right, the gas was taken from your drama club." Bai Qirun said, "Actually, the first time I came here to watch, the gas trap was still empty, so we didn't pay much attention to it. But last night, just in case, One, we came here again and found that these traps were indeed newly filled with hypnotic gas, so Brother Lian was convinced that the murderer wanted to do something to you here. In order to ensure your safety, he let me drop the bag into the jar gas."

"Such a big thing, why didn't you tell me in advance?"

"I wanted to tell you in advance, otherwise, with your on-the-spot reflexes, you would definitely fail in front of the murderer. But Brother Lian has confidence in you, so he didn't let me tell you." Bai Qirun said, "Hey, now It seems that this confidence is so outrageous—without brother Xian's reminder, what can you see?"

"What kind of confidence is this? You keep it secret while expecting me to cooperate with your plan. Do you think I have spoilers?"

"What kind of spoiler cheat? We think you have the same level of brain as Brother Xian, thank you!" Bai Qirun said speechlessly, "Ah, they are obviously similar genes, how can there be such a difference in IQ?"

"..."

"By the way, let me explain to you again—we entered through another entrance, not the one you left today, but I know the way you left because I already got the floor plan."

"Send me a copy."

"Yeah." Bai Qirun replied lazily, "Okay, I've already told you all I know. As for Brother Lian's other arrangements, I really don't know. He doesn't seem to intend to tell me. Of course, In fact, it is not difficult to guess—”

"According to the current development, I guess," the sound of eating potato chips came from the phone, "the murderer is dead."

"Hey, suddenly I feel a little sympathetic to this murderer." Bai Qirun's mouth was full of potato chips, and he sighed with feigned sympathy, but the meaning of looking forward to a good show was beyond words, "If he captures you, at least there is a 0.1% chance of survival. You can fight, can't you? But I prefer to catch Brother Lian, um..."

The voice on the phone suddenly became clear and determined: "He will definitely regret being born in this world."

Every single word made Du Ruoying's vague premonition instantly condense into a complete image——

The murderer is in danger!
