The Chan Sect Has Golden Immortals

At the moment of his death, the soul of a modern man with cancer unexpectedly transmigrates to the Primordial World and inhabits a stone almost exactly shaped like a human. After endless ages, he finally takes on a physical form. By a twist of fate, he becomes Yuanshi's disciple and from then on takes part in the struggle to survive in the Primordial World.

He witnesses the true Three Pure Ones and the great powers of the Primordial World, lifting the veil that has obscured its true nature. The Primordial World is no legend, but a real place. Laozi, Yuanshi, and Tongtian are nothing like the figures described in later generations' tales.

Is the Heavenly Dao impartial, or does it show favoritism?
