[No Romance + No Female Lead + System + Crime Solving + Secret Identities + Transmigrate] After pulling an all-nighter and suddenly dying, Bai Yan opened his eyes to find that he had become a different species: a long, white snake. He witnessed a murder from the start. Talk about a thrilling beginning. As the only witness, Bai Yan felt his poor little heart couldn’t take it. Luckily, the System finally showed up at the crucial moment. “Hello, Host. I’m the Crime-Fighting System. Please report this to the police immediately.” Bai Yan: ??? Officers, interested in working together? Later, Captain Zhang Cheng of the criminal investigation squad received a mysterious call. There was no caller ID, and they couldn’t find any information about the caller. Bai Yan: Captain Zhang, I’m interested in your cases. And so, the police squad gained a mysterious “unofficial member.” He pursues suspects by climbing, searches for evidence by squeezing into tight spaces, and identifies culprits by scent. Zhang Cheng: Who are you? Bai Yan: Remember this, your man’s name is Bai Moxun. And so, the name “Bai Moxun” became legendary. They say he can always find evidence no one else would expect. Zhang Cheng: ...I don’t know why, but every time we arrive at a crime scene, there’s a snake wandering around. (ー_ー)!! Please mind your own triggers. Be gentle, thanks.
