As the battle generals and leaders of the Nether Army, sheer combat power is not enough.
Every battle general and leader, as they improve their strength, also undergoes a series of command exams specially designed by Catherine.
These exams, of course, do not involve answering test papers.
Instead, it involves experiencing the battlefield firsthand.
Except for those who entered as backup battle generals, the seasoned leaders and battle generals of the Palace of the Nether King have all emerged from one bloody and fiery trial after another.
Zu Gu is certainly no exception.
In the eyes of most people, he is just a funny guy who isn't very serious, loves to brag and joke, or pull Quentin to tell some dirty jokes.
But once he starts fighting, Zu Gu completely changes his mindset.
For him, combat power and intelligence are both indispensable.
Otherwise, he wouldn't be alive today.
