One hundred thousand years ago, the Tianlan Sect dominated the cultivation world, and all the disciples in the sect were geniuses, invincible. Only the founding disciple Xu Yang had always been in the Qi Refining Stage. In order to break through his cultivation and ascend to heaven as soon as possible, Xu Yang secluded himself for ten thousand years. Who knew that when he came out of seclusion, the cultivation world had already declined, and there were only three or five disciples left in the Tianlan Sect. Seeing that the sect was about to be destroyed, Xu Yang fought off the powerful enemy and vowed to lead the Tianlan Sect back to the top! As the power of the Tianlan Sect expanded, the truth about Xu Yang's stagnant cultivation was gradually revealed. During the past ten thousand years, a secret that runs through the three realms of humans, demons, and immortals was also revealed to everyone! Is it a thought to become a god, or a thought to become a demon? The life and death of the world is in the hands of Xu Yang!
