Infinity: After Losing My Memory, Was I Treated as a Mole?

I am Zhou Ye. Some people say I am the executioner. I don't remember. When I woke up, I couldn't remember anything. Family, identity, upbringing - nothing. Only the knife in my waist reminds me that I will kill people. They say that we are reincarnators who were thrown into this place called Red Village by the Lord God and have to live for seven days. But there was an undercover agent from the Bloody Squad mixed into the team. I don't know who is undercover. I don't even know if I am.
