The story begins in a utopian secret realm - Shuiyue Cave. The Tong family has supernatural powers and has been hiding from the world for five hundred years. Because the patriarch is seriously ill, the three brothers go to the world to find medicine, but unexpectedly encounter the bloody storm and family feud in the outside world.
This is not only a story about "killing monsters and upgrading", but also a tragedy about fate and resistance. The eldest brother Tong Bo (played by Yu Bo) struggles with near-perfect divinity and humanity, the second brother Tong Zhan (played by Yang Junyi) grows from a reckless boy to burdened with the fate of the family, and the third brother Tong Xin (played by Zhang Jin) loses and returns to his innocent heart, forming one of the most touching brother portraits in the history of Chinese television.
