Introduction: One hundred thousand years ago, Tianlan Sect reigned over the cultivation world. All the disciples being geniuses made it invincible. But Xu Yang was an exception. He had been a disciple since the founding of the sect, but he got stuck at the Qi Refining stage. To make a breakthrough and get leveled up as soon as possible, Xu Yang went into seclusion for ten thousand years. When he came out, the cultivation world had already declined. Tian Lan Sect was also about to be extinguished with only three or five disciples left. Xu Yang fought off strong enemies and swore that he would lead the Sect back to the top! As the Sect expands, the truth about Xu Yang's stagnation in cultivation is revealed step by step. So is a mystery that runs through the three worlds of human, demon and immortal.
