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

"What do you want to do to me?" Xu Fu trembled uncontrollably.

"You might as well guess." William smiled slightly.

"I... I am innocent," Xu Fu swallowed guiltily, "If you dare to mess with me, the law will not let you go!"

"Don't worry, I won't mess with you," William put on the mask and gloves, "You just accidentally inhaled the leaked hallucinogenic gas during the fight with me, and when you were unconscious In the state, one foot is unsteady, slipped and fell into the acid pool, that's all."

"You can't... um!" Xu Fu, who was put on the oxygen mask, struggled desperately and writhed, and his breathing became more and more heavy, "They will come soon, they... that policeman... will not agree with you to do this !"

"They?" William raised the corners of his mouth slightly, "Don't worry, under my arrangement, they will be the best witnesses - to witness the last scene of your life. It just so happens that if there is a policeman in the audience, this scene could be more believable. Don't you think so?"

"Save... let me go... please..."

"Do you remember what you said when the four victims begged you for mercy?" William asked. "You said—you enjoyed their terror."

"Do not……"

"By the way, Qi Run, send them away first, I still need some time."

"No problem." Bai Qirun put down the potato chips, pressed Enter, and manipulated a mechanism opposite to William's to make a sound, successfully drawing Du Ruoying and Du Ruoxian away.

William carried an empty transparent plastic bucket to the petri dish containing the corpse, and picked up a small half bucket of black-green solution under the water pipe that transported the strong acid.

"It should be commended that you have prepared a complete set of things, which can save me a lot of effort." He said to Xu Fu.

Although he knew that Xu Fu could no longer hear his words at this time.

The fear on his face is being eroded by distorted joy little by little, his eyes have become very hollow, the corners of his mouth are twitching, and a line of silvery saliva is flowing down uncontrollably. Obviously, the overload of pleasure is affecting his nerves. The center has caused irreversible damage.

William removed the oxygen mask in satisfaction, and helped Xu Fu to the corridor.This place used to be a water boiling area. A circle of rusty steel-framed corridors surrounds a pool that has sunk by nearly one level. The pool has been dry for many years and is covered with thick dust.

William found the water gate of the pool and unscrewed it, and the pool soon filled with dirty water.He poured all the solution in the plastic bucket, and then threw in the empty bucket, gloves and masks.

On the other side, Du Ruoying and Du Ruoxian, who heard the sound of water, realized something was wrong, quickly turned around and rushed towards this side.

"Now," William let go of Xu Fu, showing a malicious smile, "Go, they are all waiting for you in front."

Guided by that gentle voice, Xu Fu raised his hands, stretched out into the void, and walked slowly forward, like a drunk chasing the fire, staggering, swaying left and right, ignorantly and fearlessly walking towards the edge of falling , to the stage called "Death".

"In the play Titus Andronicus, Shakespeare concludes the villainous Tamora with these words," said William indifferently, "'This woman lived a life as merciless as a beast, and after death Nature deserves only the sympathy of beasts.'[1]”

Finally, Xu Fu stepped on the ground and fell forward, pressing on those rusty railings. Those railings that had not been repaired for a long time were already dilapidated and could not bear his weight at all, and they collapsed and broke one after another.

Just when he was about to fall into the acid pool, a pale light flashed by, and at the same time, a long and powerful hand grabbed Xu Fu's arm suddenly.Despite the extremely dim vision, William still recognized the figure——

It's Du Ruoxian.

Under the collision between him and Xu Fu, several rusty iron railings fell loose and fell into the pool, causing the water in the pool to bubble up. Light smoke.

Du Ruoxian finally realized what was in that pond.Even though he has long been accustomed to all kinds of horror scenes, he still can't help but feel a little chill down his spine.

Du Ruoying stopped William who was trying to get close: "That's it, Will!"

"You are really as blind and naive as ever, Xiaoying." William shook his head helplessly, "He has already destroyed all the evidence of his crime with strong acid just now, and he has no intention of prosecuting him at all. If we let him go now, then The four bloody cases will never have a chance to be rehabilitated."

"I don't care what he destroyed, you can't kill him!"

"I didn't do anything," he shrugged, and turned his gaze to one side, "You saw it too, he fell by himself." As if he had found something interesting, he suddenly chuckled.

He raised his hand to hold the flashlight in Du Ruoying's hand, and blocked the light socket with his palm, and the surrounding was once again plunged into deathly darkness.

"It seems that all this will not end here." In the dark, Du Ruoying heard William say this.

Before she could react, there was a muffled groan from Du Ruoxian's side, followed by a loud sound of heavy objects falling into the water and a miserable and terrifying wail.

"What's wrong?!"

Du Ruoying withdrew the flashlight from William's hand and shone it on Du Ruoxian, only to see him clutching his arms tightly, with blood oozing from his fingers——

he is injured!

Fortunately, people did not fall.

Du Ruoying couldn't help but breathe a sigh of relief.

The one who fell was Xu Fu. Under the crazy corrosion of strong acid, he had already condensed into a mass of black mass in the center of the pool, like a scorched meat ball fried in a frying pan, bubbling in the boiling acid water, producing A large amount of foul-smelling gas rushed straight up, and the smell was disgusting.

The water in the pool boiled more and more violently, splashing in all directions, falling on the ground, walls, and even the ceiling, corroding everything it splashed into mottled and rotten.

"What a pity," William stepped forward to help Du Ruoxian up pretending to be concerned, and checked the wound for him. It was a scratch caused by a sharp blade. Will it be impossible to catch the murderer? This kind of wound must be dealt with quickly."

Du Ruoxian glanced at his feet, no blood was found on the gap in the thorny railing, he frowned hesitantly.

"Will, what the hell did you do?" Du Ruoying asked in shock.

"What I did—isn't it obvious at a glance?" William calmly wiped the stains on his face, his movements were as graceful as a demon, "I was standing in front of you all the time when Officer Du pulled him up , didn’t move at all. You should know this better than me.”

"You!" She was at a loss for words.

As he said, during the process of Xu Fu's fall, he stayed in place, holding the flashlight with her. At such a close distance, no matter how subtle and abnormal movements he made, it would be impossible for him to fall. Impossible to escape her detection.

Did he really do nothing?

Or did he secretly command Bai Qirun to manipulate a certain mechanism that hurt people?

no, no...

This is impossible!

Du Ruoxian's position was very random. At that time, it was dark again, and there were so many obstructive railings covering him. It was impossible for such a light and small sharp blade to achieve a precise attack through the mechanism without leaving the slightest trace afterwards.

Moreover, this kind of cut with just enough force is more artificial than a mechanism...

Although she didn't know what happened, Du Ruoying was sure that William was by no means as innocent as he appeared on the surface.

"I'll figure this out sooner or later, don't try to fool me!" She said angrily.

"Valent anger will only expose the incompetence of the weak." William's eyes drifted indifferently to a corner, where a thin figure was trembling in the darkness, "If you are really dissatisfied, try to come Sanction me - if you can."

It's not "blocking", but "sanctioning"...?

Du Ruoying looked at him with a provocative smile, cold, hypocritical, without the slightest warmth, as familiar as ever.But strangely, this time she felt a little strange——

It was an imperceptible bitterness.

Is it... an illusion?

Thinking of this, an unspeakable tingling pain suddenly passed through his heart.

"I will do it." Du Ruoying secretly clenched her fists.

If that's what you're looking for...

"Let's save gossip until we go out. It's not safe here," William said. "The highly reactive acid is splashing everywhere, and the poisonous gas produced has already diffused up. The air circulation here is very poor. If you stay too long, even Our lives are also in danger."

Despite his doubts, Du Ruoxian understood that what William said was true—the strong acid in the pool was black and green in color, corroding metals and corpses at a rate far faster than aqua regia, but to the Teflon plastic bucket floating aside Helpless, it can be seen that its main component is likely to be fluoroantimonic acid, and being splashed by it is no joke, and the fluorine gas produced by it is also fatally toxic. [2]

Seeing that William was going in the opposite direction from their previous direction, Du Ruoying felt a little suspicious: "Why are you going this way?"

"The maintenance shaft at the southeast end is too far away from our current position, there is a closer exit here," William explained, "Follow me, watch out for footprints."

The two had no choice but to follow him out from another exit and contact the police to deal with the scene.

"The situation at the scene is basically consistent with what Professor William said." Officer Lu took off his gas mask and walked in front of Du Ruoxian who was wearing a thin blanket. "According to the biological traces we found, it can be proved that Xu Fuxian handcuffed William." On the operating table, he was forced to inhale the hallucinogenic gas, and then William broke free. The two had a scuffle and struggle. It was probably at this time that Xu Fu accidentally inhaled some hallucinogenic gas. In a state of unconsciousness, he himself Stumbling to the edge of the hallway, almost falling - and then there's the stuff you're trying to fish for and not getting."

Du Ruoxian nodded: "Did you find any blood on the railing?" Seven

"Yes, but I don't know if it's your blood, I have to take it back for testing."

"I'm afraid it doesn't make much sense," Du Ruoxian pondered, "What about the four glass jars, did you find anything?"

"As he said, it was filled with strong acid, so the victim's DNA should not be extracted. What's more difficult is that we didn't find any traces of the victim in other places in the basement." Officer Lu said helplessly Taking a deep breath, "If Xu Fu is really the murderer, there is nothing he can do - fluoroantimonic acid is a nationally controlled product, and the tank of hallucinogenic gas in the operating room is an illegal drug. Following the clues of illegal transactions, Maybe we can find something."

"Well, according to the professor, fluoroantimonic acid should be used by the murderer to process the victim's internal organs. This kind of strong acid is not resistant to storage, and must be purchased again every year. If Xu Fu's purchase records can be found, and the purchase time can be compared with the The disappearance time of the four victims matches up, which is indeed a good direction." Du Ruoxian lowered his eyelashes, "By the way, is there anything unusual about the scene?"

"Yes, I was just about to tell you about this," Police Officer Lu handed over his mobile phone. On it was a photo of the ground, where the footprints of the four of them could be seen. In addition, there was a trace of dragging , "This is the scene of the corridor where Xu Fu fell into the water. I found a drag mark, which is very new and extends to the side of your footprints, but none of you mentioned it, and there is nothing in the testimony that can explain this trace clearly from the side. reason."

"But this trace, I don't remember it at that time..." Du Ruoxian suddenly realized halfway through the sentence, "So it is. No wonder he mentioned 'the old exit in the southeast direction' and told us to 'watch out for footprints'."

"What do you mean?"

"That passage was not meant for us," Du Ruoxian suddenly lowered his voice, "At the scene——"

"I'm afraid there is still a fifth person."
