Xu Yang was the founding disciple of the Tianlan Sect one hundred thousand years ago. His master ascended and he continued to refine Qi. Ninety thousand years later, his martial nephew ascended and Xu Yang was still refining Qi. He continued to do so even when the old gatekeeper of Tianlanzong ascended fifty thousand years ago. When the old tree at the foot of the mountain became a demon thirty thousand years ago, Xu Yang was still refining Qi in order to pass the catastrophe. Zhang Wuji, the 9872nd generation disciple of Tianlanzong, ascended ten thousand years ago while Xu Yang quietly refined Qi. He spent the next 10,000 years in seclusion, finally breaking through the 9999th floor of the Qi refining period. Another ten thousand years later, Xu Yang emerged from seclusion after breaking through.
