After investigation, Ma Yu is Ma Qi's cousin. His number was used to hide his underground romance with Lu Wenwen. Ma Qi and Lu Wenwen are college classmates and lovers, after graduation, Lu Wenwen was signed by Qingcheng Media and became popular, and Ma Qi also followed Lu Wenwen to join Qingcheng Media, but it has been tepid, due to the company system and the relationship between artist status, the two have been in a secret underground love.

March: "How so..."

In the interrogation room, March was extremely mentally unstable. Chronic sleep deprivation and high-intensity work left March in a trance. Due to the lack of surveillance, except for Lu Wenyu's game records and his long-term voice connection with his friends, it can be preliminarily proved that he did not commit the crime, and neither Ma Qi nor Zhang Zichen has any evidence to prove their claims. As far as the relationship between March and Lu Wenwen and his attitude during the interrogation are concerned, it is clear that Ma Qi did not have a motive for killing Lu Wenwen. Is it really because Lu Wenwen had the idea of suicide and happened to be drugged by Zhang Zichen and attacked by Lu Wenyu, a series of coincidences led to an accidental death of a heart attack? At this time, the detailed medical examination report came: the deceased's lungs were blood-colored and white foam, and it was found that the deceased's blood contained a large amount of carbonic acid, and the potassium content was far beyond the normal level. It is presumed that the deceased was due to respiratory acidosis caused by excessive carbon dioxide inhalation.

Fire extinguisher?! I remembered the clues provided by the apartment administrator, so I immediately contacted my colleagues in the trace examination department to check the fire extinguisher in Lu Wenwen's room. The fire extinguisher in Lu Wenwen's room has really been used up, and as I expected, the meticulous murderer has cleaned up his fingerprints. I think of Zhang Zichen's blackened little finger and the erythromycin ointment found in his room during the search, which is the most convenient medicine to treat frostbite, for a petite girl, the weight of the fire extinguisher is not light, in the process of continuous use, one hand pressed the switch and the other hand held the fire extinguisher and accidentally frostbitten fingers.

The evidence was conclusive, and Zhang Zichen confessed to his crime.

Jiang Chen: "Why are you doing this?" ”

Zhang Zichen: "I have been working as an assistant here since I graduated, and the company induced me to sign an unreasonable binding agreement for 20 years, if I leave without authorization, I will face a huge amount of liquidated damages, the so-called assistant, I want to call it a slave is more appropriate." For so many years, there has not been a day without fear, which is also a relief.

Me: "Why did you send Lu Wenwen's photo to Lu Wenyu?" ”

Zhang Zichen: "I have long known that Lu Wenyu has bad thoughts about Lu Wenwen, so I secretly sent the photo to Lu Wenyu, I hope he can succeed in making Lu Wenwen compliant, if the two have an improper relationship, then as a life assistant, I will definitely be able to collect evidence from it, and then publish it to push the two into the abyss of no return." ”

Jiang Chen: "Why did you choose to do it yesterday?" Last night, to be exact? ”

Zhang Zichen: "I didn't leave immediately after Lu Wenyu entered the house, I eavesdropped outside the door for a while before I learned that Lu Wenwen actually had Lu Wenyu's handle in his hand, which means that even if I gave Lu Wenyu an intimate photo of Lu Wenwen and Ma Qi, my goal could not be achieved!" This dashed the last shred of hope I had, so I had to do it myself, and I heard the sound of the two fighting outside the house, which was also a good opportunity to blame the others. ”

Zhang Zichen confessed that Lu Wenwen's room card had always been in his hands, and he sneaked into his room after confirming that Lu Wenwen was asleep at 23:00 yesterday, dragged him into the bathroom, closed the exhaust fan, half-covered the door, and sprayed it from outside the door with a fire extinguisher, and frostbitten his little finger in the process. At 7:00 the next day, Zhang Zichen deliberately knocked loudly on the door to attract Lu Wenyu to open the door together, and opened the exhaust fan first while he was not paying attention, so as to prevent leaving clues, and then witnessed Lu Wenwen's death with him and called the police.

Zhang Zichen has always had a grudge against Lu Wenwen, and the peace on the surface can't extinguish the burning anger in his chest after all, as long as he tears a small hole, madness will gush out of it. After learning that he couldn't borrow Lu Wenyu's hand to get Lu Wenwen, Zhang Zichen decided to take a desperate gamble and use his own methods to avenge himself. But she underestimated justice and the police's ability to uphold social peace and justice. She will pay the price for her actions. If Lu Wenwen hadn't bullied Zhang Zichen, Zhang Zichen might not have secretly taken photos of her and Ma Qi and sent them to Lu Wenyu; If Lu Wenyu hadn't used this to blackmail and plot wrongdoing, maybe his ugly things would not have been exposed; If Lu Wenwen hadn't bullied Zhang Zichen, maybe nothing would have happened. People always have to pay for their actions.
