Escape the Library

【Chemical Reaction-12】

As a girl from the Environmental Academy, Lin Manluo had never even seen the corpses of kittens and dogs in school, not to mention human corpses. Since she came to the library, her psychological endurance has been constantly refreshed. Now, she actually has to pick up the bones from the waste water pool! This scene is really unforgettable, and if you are not careful, you will have nightmares.

Qin Lu's face was also pale, but she still didn't feel embarrassed to back down. Instead, she gently stretched out her hand and squeezed Lin Manluo's left hand to cheer her senior sister up.

Lin Manluo bit her head and summoned the vine again.

The waste water pool is very corrosive, but fortunately, her vines can continue to grow and spread forward. She searched again according to the position of the bones she had just found, and soon found some bones.

Jiang Pingce looked at the more and more bones at his feet, and said to Liu Zhaoqing, "Senior brother, can you splice these broken bones together?"

Liu Zhaoqing simply stepped forward, quickly wrapped several layers of thick gauze on the outside of the gloves, scratched the bones on the ground, and said, "Of course, what Manluo fished out just now were the tibia, fibula and humerus, that is, the limbs. Part. No spine found... Did the murderer still shred the body after the murder?"

Xin Yan said with a cold face: "Even if the chemical can corrode the corpse, it will not break all the bones. The murderer should cut the human body into several parts after killing the person and then throw it into the waste water tank, so that the corpse can be corroded as soon as possible. "

Yue Xingwen resisted the nausea and frowned: "It seems that the murderer is not only for revenge, but also a psychopath. I think that Zhou Qiqi's suspicion has become lower. A girl in her twenties should not be that big. The body of an adult male was moved vigorously, and the body was cut into parts and thrown into a waste basin."

At this moment, Liu Zhaoqing suddenly said "hey", squatted down, and carefully touched the fractured surface of the bone with his gauze-wrapped hand, and then came to the conclusion: "Where the bone was broken, there was no comminuted fracture. Very clean and neat, it should have been cut quickly with a sharp weapon." He straightened up, looked at Yue Xingwen, and explained, "That is to say, the murderer didn't chop the body like a butcher chopped meat, but chose to A very sharp tool to divide the body."

Yue Xingwen asked doubtfully, "Could the murderer still understand medicine?"

Liu Zhaoqing shook his head: "That's not true. If you understand medicine, you shouldn't cut like this. Many bones are cut from the middle, so it should be a layman. I prefer that he has tools that can quickly divide the body. Ordinary knives and axes , it is impossible to chop the bones so neatly, but the chainsaw we use for surgery can quickly cut through the bones."

Qin Lu's hand trembled slightly, and she said in a trembling voice, "Electricity, chainsaw horror? Has this turned into a horror movie?"

Thinking of the image of a person lurking in a chemical factory dragging a body here in the middle of the night and sawing it open, Lin Manluo's heart couldn't help tensing. She exhaled lightly, quickly adjusted her mood, and continued to bite the bullet and wander around in the waste water pool. Search for scattered human bones.

Suddenly, her vines entangled a relatively large heavy object, Lin Manluo pulled it gently, realized that something was wrong, and immediately said to Yue Xingwen: "Xingwen, I don't know what it is over there, it doesn't look like a bone. weight."

Yue Xingwen immediately raised his right hand cautiously and summoned a dictionary of idioms, staring at the dark brown surface of the waste water pool: "Senior sister, be careful, pull it over slowly."

Lin Manluo's vines can stretch, shrink, or strangle prey at her command, so she pulled the thing to the edge of the pool without much effort.

Qin Lu leaned over to take a look and almost fainted on the spot!

Xin Yan turned his eyes away with a sullen face, and Liu Zhaoqing once again burst into foul language: "Fuck! Fresh corpse that hasn't been decomposed!"

Jiang Pingce has always been calm, overcame the psychological obstacle quickly, and squatted down to observe the **** mass.

Seeing his serious observation, Liu Zhaoqing couldn't help but ask, "Don't you feel sick, Jiang Pingce?"

Jiang Pingce said lightly: "It's disgusting, but we have to seize the time to solve the mystery."

Yue Xingwen also stepped forward and squatted beside Jiang Pingce, observed carefully, and analyzed carefully: "It seems that this person did not die for a long time, and the chemicals in the waste water pool only corroded him beyond recognition. I haven't had time to corrode the bones. What Senior Sister fished out happened to be the upper body."

Jiang Pingce asked in a low voice, "Can you confirm your identity? Could it be Chen Xiumei who resigned today?"

Yue Xingwen actually had a vague feeling that since the three people who resigned before were killed, will Aunt Chen Xiumei who resigned today also be killed? Now that fresh corpses are found in the wastewater pool, it is easy to think of Chen Xiumei who left the factory in the afternoon.

However, the corpse was corroded into a **** mess, and there were few intact skins on the body, and the face could not be seen at all.

Yue Xingwen observed for a moment, and suddenly his eyes were fixed on the neck of the corpse. Jiang Pingce keenly noticed Yue Xingwen's gaze, and pointed to the neck: "Is this jewelry?"

Yue Xingwen frowned and said, "Brother Liu, please give me some gauze."

Liu Zhaoqing quickly wrapped several layers of protective gauze around Yue Xingwen's gloves. Yue Xingwen then stretched out his hand and picked up the thing hanging on his neck and observed it carefully. Unable to light the alcohol lamp, Yue Xingwen narrowed his eyes and looked at it carefully for a moment, and a picture suddenly flashed in his mind——

In the staff cafeteria this morning, when Chen Xiumei passed him with a plate, she did wear a necklace on her neck.

That's right, it's the Jade Buddha!

There is a folk saying that "men wear Guanyin and women wear Buddha". People who wear jade Buddha either believe in Buddhism in the first place, or something happened in the middle, and they want to wear jade Buddha to exorcise evil spirits and avoid disasters.

At that time, he also thought, was Chen Xiumei guilty of being a thief and always having nightmares, so she asked a Jade Buddha to keep her safe?

The red rope hanging on the jade Buddha is indeed very similar to the red rope that remains today; and the shape of the thing in the palm is also very similar to the jade Buddha, but the jade has been corroded by more than half, leaving only the incomplete A piece the size of a fingernail.

Yue Xingwen said firmly: "This is Chen Xiumei's corpse! I saw the jade Buddha necklace on her neck this morning. Although it was partially corroded, the chain still has the shape of a pendant, which is the same as what I remember. exactly match.”

Jiang Pingce nodded in agreement: "Well, I also saw the jade Buddha necklace she was wearing. In this way, Chen Xiumei was killed by the murderer after leaving the chemical plant. The murderer transported her body to the wastewater treatment workshop, cut it into several parts and put it in The waste water tank. Since the body was put into the pool for a short time, and it has not been corroded cleanly, we let us salvage it."

Lin Manluo remembered that this afternoon, she took her resignation letter and told her boss, "I want to go home and find a leisurely job." At that time, she tried her best to keep calm, and hurriedly packed up and left...

Unexpectedly, he could not escape the poison of the murderer!

A very big living person, but now it has turned into this **** appearance, Lin Manluo resisted the urge to vomit, continued to salvage in the waste water tank, and quickly fished up other parts.

Liu Zhaoqing pieced together beside him, and actually made up four corpses.

As he fought, he complained: "I have been studying medicine for so many years, and this is the first time I smashed corpses into pieces. Fortunately, I finally found all the body parts of the four deceased. It took me so long to find the body parts."

Lin Manluo didn't know whether to laugh or cry: "Senior brother, stop joking, I don't want to dream of picking up corpses."

Jiang Pingce asked in a low voice, "Are you sure that everything is in order?"

Liu Zhaoqing nodded: "Well, the four corpses are complete, and they should be the four people who resigned and disappeared. The light is not bright enough. If I move out during the day, I can analyze who is who based on their height and body shape."

At this moment, Xin Yan suddenly walked over to Yue Xingwen and whispered, "Can you show me the jade Buddha necklace?"

Yue Xingwen opened his palm and handed the Jade Buddha to him.

Xin Yan took it through the gauze, looked down for a moment, and said, "As long as what Chen Xiumei bought is not a fake glass imitation, then the Jade Buddha should be polished from natural jade, and chemicals that can corrode jade are not many……"

Jiang Pingce stood up and asked Xin Yan, "Can you identify what chemical it is?"

Xin Yan thought for a moment, then raised his head, looked at everyone and said, "It should be hydrofluoric acid."

Seeing the doubts on the faces of the classmates, Xin Yan explained in a low voice: "This is a very corrosive acid, which can corrode metals, glass and objects containing silicon. The main component of jade is silicon dioxide. Silicon dioxide itself. It is an acid, and 'acid' usually has difficulty reacting with 'acid', but it can chemically react with hydrofluoric acid to produce silicon tetrafluoride, a gas."

Jiang Pingce, who is also a science student, immediately understood when he heard this: "In most cases, 'acid' and 'base' react to form 'salt' and 'water'. It is indeed uncommon for acids to react with acids. From this point of view, the corrosive chemicals added to the waste water tank are likely to contain 'hydrofluoric acid', otherwise, even the jade will not be corroded."

Xin Yan nodded: "That's right. I just prepared something like hydrofluoric acid during the day."

Yue Xingwen's eyes lit up: "Is this the task that you said Lin Yusen arranged for you? He asked you to do the hydrofluoric acid preparation experiment and give some experimental data?"

Xin Yandao: "At that time, Ke Shaobin analyzed that this should be a side quest issued by an NPC in an online game. If you do it right, you will be rewarded with a score for the final clearance. If you do it wrong, it will not affect the clearance. Now it seems that it is not a side quest. "

He paused, narrowed his eyes slightly and said, "It's the main quest."

Yue Xingwen clenched his fist lightly: "Lin Yusen is a top student in the School of Chemistry, he understands the preparation methods of various chemicals, and he asked you to prepare hydrofluoric acid because of what he discovered, or...he The murderer?!"

Just as Yue Xingwen said this, suddenly, a harsh alarm sounded in his ears.

Drop drop, drop drop-

The decibel of the alarm sound was so high that it almost penetrated the eardrum and pierced into the depths of the brain. The six people were so clamored that their headaches broke. At the same time, Ke Shaobin and the others who were far away in the dormitory also heard the alarm. Greetings: "Are you all right? Where did the sirens come from?!"

Xu Yishen also said: "The sound seems to be the direction of the waste water pool?"

Xin Yan's face changed suddenly: "Oops, Qin Lu quickly retreat!"

As soon as he finished speaking, Qin Lu immediately took out the globe and directly shifted the plates to teleport everyone to a distance.

The next moment, there was a loud bang in my ear——

The waste water pool actually exploded in an instant!

The sky is full of firelight against the dark night sky, the flames are raging, and the smoke is billowing.

If they ran a little slower for 1 second, they would have been burned to ashes by this time!
