Chasing the Murderer After Death

I am Qi Yang, the most famous private detective in H City. I have solved many cases, only to be killed by a bullet from the back. The gunman was like a ghost, and the scene was clean and almost perfect. I only had time to leave an inverted triangle symbol in the pool of blood, and it became the most ugly unsolved case in my life. But I didn't disappear completely. I am stuck in the world as a soul, unable to show up, speak, or truly touch this world. Every time I get close to a living person, every time I interfere with reality, it will accelerate my dissipation. Until I met Huang Ran. A college student who lost his parents three months ago and still refuses to believe in the "accidental massacre". One night, for the first time, I heard the strange noise I left behind. We soon discovered that behind the bullet that killed me, the way Huang Ran's parents died, and several unsolved murder cases that were hastily closed, there were traces of the same kind of excessive calmness, excessive cleanliness, and excessive "perfection." That's not a murderer. It is a dark web dedicated to creating perfect crimes. A disappearing detective of the dead. A living young man with a blood feud. If I can still send the truth back to the world before I disappear completely—— This time, it's the dead man's turn to pursue the murderer.
