The Unrivaled Little Immortal Doctor

To protect his junior sister, a young man leaves the depths of the mountains. With a healing gourd in his left hand and deadly flying needles in his right, he can make money and save lives at the same time.

Whether you wield overwhelming power or possess wealth rivaling a nation, you must bow your head before me.

Remember this: if I shun the world, heroes will rise together. If I enter the world, no one can match me!
