Lin Longshan shook his head. “How could I possibly know?”

“When the corpse turns black and doesn’t decay, there are two possibilities. The first reason is that it was poisoned by corpse toxin, which would turn it into a zombie shortly after. The second one is that the victim had eaten a lot of mercury or heavy metals, which poisoned him to death. Mercury can preserve the body, preventing it from decomposing. However, it will turn the corpse black…”

Lin Longshan said nothing. He looked at the corpse with a guilty conscience.

I could guess the reason for Zou San'er’s death. He likely disobeyed his team leader or offended someone here. He was thus tormented to death.

In short, he was murdered.

Unfortunately, I was just an otherworldly merchant, not a policeman. This was the sort...
