Wang Hu, who possessed information imparted to him by Silly Girl, knew very well just how strong the peak-level Third Realm was.
The level of strength among fellow Third Realm—or Divine Body Realm—cultivators varied greatly.
Take the current Wang Hu that had attained Divine Body Realm after nine rounds of metamorphosis for example.
Excluding his special abilities, his current combat strength was equivalent to a Wang Hu that had undergone eight rounds of metamorphosis and grew to a shoulder height of 15 meters; or seven rounds of metamorphosis and a shoulder height of 20 meters; or six rounds of metamorphosis and a shoulder height of 25 meters; and so on and so forth.
By using a shoulder height of five meters as half a level, even if he didn't use his special abilities, he would still be able to fight beyond his level against the vast majority of living beings.
