The Eighth Book by Lost Gobu

[Fantasy with a creative premise + Leveling-up progression + Ruthless and decisive + Gets better the more you read]

Li Yi, a man determined to make something of himself, brings the ancient profession of shamanic medicine to another world. From the start, he becomes a servant of the Tang family in a corner of the Eastern Wilderness.

He had planned to quietly build up his strength, but because he was exceptionally gifted in one particular area, the Tang family's six widows took turns draining him.

To stay alive, Li Yi has no choice but to cultivate with all his might, setting out from a small town to explore the outside world using a completely different system.

Thousands of years later, a rumor spreads across the world: a Great Emperor had followed an unconventional path to enlightenment and subdued the Eight Wildernesses!
