The emperor became friends with the queen mother.

The queen mother gives the emperor a peach that will give him 999 extra years to live.

When the peach is being served someone snatches it.

The person got caught but he took a bite of the peach.

He got  taken away by the guards and the emperor says that the peach can not protect him from execution.n

The emperor died later even though he ate the rest of the peach.
