Zhou Chun's expression was slightly surprised, feeling quite astonished by this.
Then he couldn't help but exclaim, "No wonder those Fifth-order Demon Kings that survived the Heavenly Thunder Tribulation all have a few life-saving tricks up their sleeves. To kill such beings, one must plan in advance to stand a chance!"
At the level of Nascent Soul Stage and Fifth-order Demon Kings, unless one uses some methods of mutual destruction or power from a higher realm, killing such beings is indeed not a simple matter.
Otherwise, the incident of several Nascent Soul Stage cultivators and Fifth-order Demon Kings falling in Jingguo Country wouldn't have shocked the high-level cultivator circles in Great Zhou Kingdom.
As a contrasting example, there are Tianjing True Person and Kuanglei True Person, both of whom survived extremely dangerous situations by knowing the way to seek survival by sacrificing an arm.
