Idea: Person is reincarnated in the wilderness of a magic world. He was not born with a system, did not get anything rare or lucky, but was instead born with a mana pool and a spell. Usually, one had to train to get this. Not him, however. He used this spell to help kill low leveled beasts | Thunder Winged Mouse | (example) and would unknowingly expand his mana and his skills power. (For this, it also requires Idea Buff) He would be able to train his Body Cultivation, and his Soul Cultivation by being within the spells range himself. Body from the weight of the gravity, and Soul from the Mana he was using up at such a fast rate.
