Lin Yan, an orphan in Qingniu Village, was born with a sealed spiritual root. His inheritance rights were taken away by his brother Lin Fu, and he became a loser who could be bullied by everyone in the village.
A flash flood forced him to die, but he discovered a fragment of an ancient book - "The Classic of Mountains and Seas" deep in the cave.
When the nine-tailed fox tail pattern appeared on the palm of his hand, and when the divine beast Lu Wu came on the clouds, Lin Yan understood: The legendary immortal who had exhausted his cultivation and descended to earth to experience was actually himself!
The sealed memories came like a flood - he was once the immortal in charge of Kunlun, Zhengxuan. In order to understand the ultimate realm of heaven, he took the initiative to leave and cultivate. He sealed the memories of ten thousand years into the fragments of "The Classic of Mountains and Seas" and resumed his path to immortality in a mortal body. But the "brother" Lin Fu in front of him was actually the reincarnation of Demon Lord Dao Yuan who betrayed him three thousand years ago.
He wants to collect the scattered volumes of "The Classic of Mountains and Seas", unblock the mythical beasts, and regain the power of his previous life step by step.
In this life, he does not want to become an immortal, but only wants to kill off the hatred of betrayal and prove my Taoist heart!
