Reincarnated After Being Bored For Epochs

This right here is Zi Zemin, the main character. A guy in his millions with enough experience to kill a God with a snap of his fingers. He reached the pinnacle of cultivation ages ago in the ancient times. Zi Zemin has no rival and can never fight for real with everything he's got without killing them. Now here he is living his life as the strongest but also as someone who can't enjoy life. "This is so boring, let's just reincarnate in a weak body and get back at the top. I can't stand this no longer!" He reincarnated BUT this time in a weak body. He wanted to challenge himself as he goes to the top again but with more powerful enemies that he will encounter in his journey. From a nobody to a Supreme God. From weak to powerful. From nothing to everything. Follow Zi Zemin as he gets reincarnated and meets many powerful beings. No harem. No romance. Heaven-defying MC. Calm MC. Merciless MC. No family. A butler, a cat and a powerful young lady joins MC's journey. I'm fairly new to the Eastern Fantasy genre so I'm doing my best to give you guys a good read. I'm a beginner in creating stories but I have so many stories in my mind that I want to write and show it you guys but I quickly lose interest. Though I'll do my best, so please bear with me. I have no upload schedule yet but it should be 5 chapters a week or if I have time I might upload more, who knows.
