Eighty years is equivalent to a lifetime for people in this world. If you don't become a cultivator, don't enjoy any resources belonging to the Li family, just live an ordinary life, then you can live your whole life without having to go to the Ancient Immortal Mountain.
But once you accept the resources of the Li family, you must fulfill this curse mission.
Even if they didn't participate in this matter, those who are related to the Li family and enjoy the resources brought by the Li family cannot hope to remain uninvolved; there is no such thing as innocence.
The saying that disasters don't affect one's family... can be said, but can the troublemaker guarantee that family members have not enjoyed any benefits before encountering the disaster?
Many in the Li Imperial Family are under eighty years old, but even more are over eighty.
