Detective from Another World: Find Those Time Travellers!

The soul of a detective who lost his name received a commission from the gods. God gave him the emerald eyes that can see through the time travellers, and asked him to go to another world to find the stowaway travellers, and recover the souls of the world in them, otherwise the other world will be destroyed. The detective reluctantly accepted the commission, but before he could ask for the details of the commission, the god kicked him into the time-traveling door. When the detective woke up in the icy snowy night of the Principality of Yom Creed, he found that he was facing the beginning of a real hell - he woke up from a freshly murdered corpse without inheriting the memory of the original owner, and standing in front of him was a law enforcement officer who was suspicious of the cause of his death. "Okay." The detective silently raised his middle finger to the god, "It seems that before I can find the time traveler, I have to find my own murderer first."
