In fact, the ancestral key was not obtained at the fourth level at all, but from the third level.

Maybe some players go through the third level and pursue efficiency too much, but they ignore something, resulting in not getting the ancestral key.

The third level needs to enter the Heavenly Palace, and then we all go to the top of the map where the emperor is located, talk to Qin Shihuang and tear down the altar, so that we can get an ancestral key.
