One Hundred Thousand Years of Qi Refining.

One hundred thousand years ago, the Heavenly Lan Clan reigned over the cultivation world, and all the disciples of the clan were proud and invincible. In order to break through the cultivation level and ascend as soon as possible, Xu Yang, the only disciple of the sect, had been in the Qi refining stage. When he came out, the cultivation world had already declined and only three or five disciples were left in Tian Lan Clan. As the clan expands, the truth of Xu Yang's stagnant cultivation is revealed step by step, and a hidden secret that runs through the three realms of human, devil and immortal is revealed to everyone! Is it a thought to become a god, or a thought to become a devil? The life and death of the world is between the palms of Xu Yang's hands!
