Lu Xiaoxian wakes up to find himself transmigrated into a conscious scroll of True Immortal Seal. To hide from the investigation of Sect Master Xuan He, he transforms and sneaks into Beichen Academy, acting as a mediocre disciple by day to conceal his talents, while crazily cultivating at night using the original source of the Immortal Seal. Song Wujiu picks up a fake immortal seal and his power surges, only to find himself turning into the spiritual power vessel of Lady Xingmo. The two join forces with the straightforward Su Xiaotang, searching every forbidden ruin and uncovering the conspiracy of Xuan He using Lady Xingmo to break through only to be exploited in return. On the day the forbidden area opens, the three combine forces to rewrite the seal and suppress Lady Xingmo. Lu Xiaoxian is granted the status of an inner disciple, but still willingly acts as an ordinary disciple: keeping a low profile is the safest way to cultivate immortality.
