Even though Li Chongmiao achieved the state of Human Immortal, a thousand years is still a rather long period for her.
Moreover, after the Primal Spirit Realm was elevated, every twelve hundred years, the beings who have broken through to the Immortal Realm must face one of the tribulations from the Three Disasters and Nine Calamities. The remaining hundred years are just enough for the retiring Clan Leader to prepare for the Tribulation Transcendence.

Therefore, the family will consume luck to help weaken the power of the tribulation, increasing his chances of passing through safely.
