There are many difficult achievements in "The Legend of Demons and Demons", and rebirth is one of them. The requirement of achievement is to defeat the collection of vengeful spirits. You need to pay attention to the fact that every time you cause attack damage to it, you will get a state effect in your hand, excluding Ao Yulong form attack.
How to do the devil-subduing scattered life
Rebirth
Defeat the collective of vengeful spirits
Every time you cause attack damage to it, you will get a status effect in your hand, excluding Ao Yulong form attack; Az's summon will not trigger this effect. Try using a single large attack instead of a small or more attacks, or if playing Aoyu, fill your hands with a curse, and use them as claw attacks in the same turn if possible.
