Everyone was fine anyway, so they all ran to Peng Sijue's office with a glass bottle on the table. Xu Xiaodong looked at the contents and exclaimed, "It looks like a dirty bag!"
"That's the liver, soaked in formalin for three years." Peng Sijue corrected.
"I know, I just thought of dirty bags... I'll buy one after get off work." Xu Xiaodong was given a white look by Lin Dongxue.
Chen Shi said: "My thinking is like this. Why do they insist on using this harmful formula? Obviously they are paying compensation every year, so there must be a profit."
"It won't take much time to know the result of the reverse process." Peng Sijue picked up the paper and pen, "I'll do the math."
Soon, Peng Sijue filled the paper with symbols and numbers, and everyone was dazzled. He kept nodding his head: "So that's it... That's it..."
Xu Xiaodong said: "Captain Peng, can you explain it?"
"Don't interrupt!" Lin Dongxue said.
After spending half an hour, Peng Sijue told them the results: “Online data shows that there are 2 million patients using this drug in the country every year, and the annual sales volume has reached 10 million boxes. I use this as a base to calculate. But the cheap substance B earns about 60 million more than the non-toxic but expensive substance A. If you remove the annual average of their compensation, it is still profitable. In a word, if you use a toxic formula, even if you fight it every year The loss of money in the lawsuit is also two percentage points higher than the profit of using non-toxic formulas."
Chen Shi shrank his pupils excitedly, "Like I guessed, they have an internal annual profit algorithm, and they count the compensation for litigation as a variable. It was not unintentional to kill people five years ago. It was within their plan and controllable. It’s just a loss."
"It's horrible!" Lin Dongxue frowned, "For the two percent profit, actually taking human lives as a trifling matter?"
Lao Zhang said: "For a large company, a profit of two percentage points is astronomical."
Peng Sijue said: "I'm just making rough calculations, but the real numbers are not too far off."
Chen Shi said: "This is a Pandora's box. Once it is made public, it is not as simple as a lawsuit. Everyone who has used this drug must be compensated until bankruptcy. So in order to keep this secret, they will not hesitate to kill. Quit your mouth."
Xu Xiaodong said: "I have the motive, but how did people kill them? Isn't it a secret room now?"
"Let's check it out again!"
Chen Shi, Lin Dongxue, and Peng Sijue came to the place where Zhu Jun, the production manager, died. This time they did not pick the lock in, but got the keys through the real estate agency.
Standing in an empty room, Chen Shi said: "The door is locked, and the only key is on the deceased Zhu Jun. How do you leave after the murderer pushes the person downstairs?"
Lin Dongxue went to look at the window sill and said, "The window sill is very narrow, but there is a sewage pipe next to it."
"Impossible!" Peng Sijue asserted, "The sewage pipe cannot withstand the weight of a person, and if there are footprints on the windowsill, the police will not fail to notice."
Lin Dongxue suddenly figured it out, "It's actually very simple! After pushing the person down, lock the door with the key, and then put the key back on the deceased person."
"You are also a way." Chen Shi said.
"After a person falls, someone around will definitely come over, can the murderer really do tricks on the corpse?" Peng Sijue expressed doubt.
"The neighborhood at eight or nine o'clock should have no people."
"If you are a murderer and plan a murder that pretends to be suicide, a little uncertainty will kill you."
Chen Shi interrupted them, "Dongxue's divergent thinking is very good. Let's think about it further. The key does not need to be on the body. Why must the deceased be in the house? The deceased was anesthetized at the time, and the murderer could drag him to it. Outside, push downstairs at other places on the same vertical line so that the key must be on the body."
"Rooftop!" Lin Dongxue suddenly realized.
The three of them came to the rooftop again and looked down. It was really high. Falling from here will definitely fall to death.
Chen Shi noticed that there was no railing on the edge of the roof, but a layer of red paint was painted on the ground to indicate danger. Lin Dongxue said, "Look down, it's scary!"
"It's actually not very painful to fall to death." Peng Sijue said.
"The few seconds in the air are scary enough."
"In the process of falling quickly, some people will faint in shock, basically not feeling it."
Lin Dongxue made a grimace, "I don't want it!" She stepped back and grabbed the corner of Chen Shi's clothes.
Chen Shi said: "If you fall from here, do you land on the front or back?"
Peng Sijue said: "It depends on the posture."
Peng Sijue's cell phone rang. After he answered the call, he said to Chen Shi and Lin Dongxue: "It was found that there is a trace amount of thiopental sodium in the liver, which is an intravenous anesthetic. It has a certain effect after oral administration, and it is not easy to detect... I have a relatively complete sample."
"The efficiency is really high!" Lin Dongxue praised.
"He's definitely killed!" Chen Shi said, "I noticed that there was a large amount of dust behind the deceased in the photo, indicating that he had been lying on the ground. He should have fallen down while lying down. He turned over and fell, facing the ground... Haha, I seem to understand. The murderer placed the anesthetized deceased on the edge of the roof, and then left. As the effect of the anesthetic gradually disappeared, the deceased turned his body in a lethargy and fell down!"
"What if the deceased turns in the opposite direction?" Lin Dongxue questioned.
"Most people sleep in a fixed posture. For example, if you like to sleep to the right, you can guess by observing the indentation on the bed and pillow of the deceased." Chen Shi said, "This trick seems simple, but the actual effect may be better than imagined. Good."
Peng Sijue looked at Chen Shi and Lin Dongxue suspiciously, and his thoughts returned to the case, "Delayed killing not only forged the accident, but also created alibi."
"He used this brilliant trick three times in a row, but it was never seen through by the police. The motives and homicide methods are all clear, so let's meet the suspect!"
"But we have no evidence yet!" Lin Dongxue said.
"Do you know any hackers?"
Peng Sijue said: "Do you want to use illegal means again?"
Chen Shi ignored him, "There may be files on the algorithm in the president's computer. If you can get it, there will be no evidence."
Lin Dongxue said: "I know one, I'll go find him."
Chen Shi explained: "By the way, ask Xiaodong to check if Hou Yue bought thiopental three years ago. It doesn't matter if you can't find it."
Lin Dongxue went downstairs first, and Peng Sijue walked behind Chen Shi and said, "Dongxue was ruined by you."
"Obviously you are on the Dao, OK!" Chen Shi smiled.
Chen Shi asked Xu Xiaodong in the bureau to check Hou Yue's current address. He came to his house alone and knocked on the door. A thin man with glasses asked, "Who are you looking for?"
"Are you Hou Yue?"
"Yeah, who are you?"
When Chen Shiliang showed out his ID, Hou Yue's expression immediately changed. He grabbed the ID and opened it. "Are you not a policeman?"
"Like the police, we have opened a case to investigate your company."
"You said that the bathing club, didn't it just stop business for rectification last week?"
"Also install garlic, I'm talking about Yuhua Company."
"Yuhua Company?" Hou Yue pushed down his glasses, "You really know how to check. I left my job three years ago."
