Shen Lian suddenly had an epiphany. Taiwei Pavilion was the foundation of Qing Xuan. Inside it, there were generations of the exploration of Dao and the many cultivation experiences hidden in it. This was the biggest treasure for a Dao sect.
No wonder the Grand Ancestor Master would always remain in the Taiwei Pavilion.
After he succeeded as the chief, from the information that he knew, it was during Zhang Ruoxu's time as chief that Qing Xuan had three immortal Zhenrens. This was considered quite a lot. As for the other teacher-elder who have attained immortality over the ten thousand years, too many could not make it through the three trials of Dao and returned to the reincarnation of the world.
Only a very small number finally transcended beyond the mortal world and left, cutting off their involvement in this universe and got one's freedom.
