The ultimate ability released by the Death Prophet in the game was invincible, but the souls he released with this ability were not invincible. Even if the damage feedback wasn't full, releasing a large number of souls only to have them wiped out by an AOE was a disaster.
Tsk, Zheng Yichen thought about it and still felt it was pretty terrible. Although he was a tough warrior himself, being on the receiving end of such an attack wouldn't be pleasant.
If this ability focused on quantity, it was quite dangerous to a certain extent. However, if he was strong enough to give those dominated souls a huge enhancement and make them invincible to the enemies, then he would become an army unto himself.
The reason Zheng Yichen understood this ability so well now wasn't that he had gained enough souls from battle, but because he had a cat spirit by his side, as well as Wise Dragon No. 9, though Wise Dragon No. 9 wasn't exactly a normal soul.
