Proving the Dao of the Profound Origin

A young man accidentally falls into another world. He masters the essentials of immortal cultivation, gathers nine heaven-defying meridians, treads the sea of primordial energy, establishes an eternal pinnacle, and lays the foundations of the Heavenly Dao. Defying the heavens at every step, he battles through a hundred lifetimes of reincarnation and finally becomes the immortal he dreamed of being, only to discover that the nightmare has just begun...

P.S. I came up with the idea for this novel after playing Xuan Yuan Sword Immortal, which inspired some of it. The beginning may seem a little cliched, but the middle and later parts are passionate and thrilling. After experiencing several dramatic rises and falls, the protagonist gradually grows as well.
