[Multiple Heroines, But No Mindless Harem]
He was reborn in the world of Naruto, during the Sannin era, and Yuan Yi was feeling rather troubled. But after awakening the Ultimate Life Experience System, he stopped worrying.
Come on, seven days of sign-in gets you the Great Art of the Heavenly Immortal, and ten days gets you the Nine-Turn Profound Art. Would you be worried?
What? You don’t know what the Great Art of the Heavenly Immortal is? Surely you know the Monkey King, right? It’s the Monkey King’s very own cultivation technique, a super-fast path to becoming a Heavenly Immortal in three years and a Golden Immortal in five! Got it?
And what’s the Nine-Turn Profound Art? It’s the cultivation technique of Yang Jian, Heaven’s number-one rebel. Ever heard of becoming a sage through physical cultivation? Bloodline limits and Kekkei Tota, what are those? Let me show you what it means to win with sheer strength, and how might makes miracles!
So, years later, Uchiha Madara looked at his two-faced Susanoo, which seemed like a little chick beside Yuan Yi’s giant heavenly manifestation, and fell into deep thought.
