Transmigration: I Became a Cult Leader

Nikolai, a womanizing former assassin, dies after being stabbed. However, instead of the eternal punishment he expected, things didn't end there for him. As he strangely finds himself transported into the body of Samir, a young… slave. As if that wasn't strange and disturbing enough, he also finds himself in possession of a strange system... The Supreme Cultist System "What the fuck? So my mission is to become a fucking cultist?” “No, not just any cultist, but the ultimate cultist. Please, the system has standards, my dear host” “…” - - - - - This is my first story, so please bear with me a little. The beginning of the story is a little slow, but it gets better, I promise. Plus, English is not my mother tongue, so the grammar here won't be the best you've ever seen. So if you find any mistakes or typos you tell me in the comments, that I'll fix it as soon as possible. Thanks for reading my book!
