During a fight, the faster one would understand his opponent, the better his chance of survival will be.
The Unstable Blood Spawn seemed to be crafted by blood magic with evilness within it. The blood magic and evil magic mixed so thoroughly that even the Buddhist Purification Talismans could only restrain it so far.
Not to mention, Jia Hao already used all of them during the transition of the blood spawn, thus reducing its strength.
He couldn't even imagine the strength of a stable blood spawn.
After fighting it, he realized that he could only kill it if he chipped away its body and kept burning it with his righteous yang energy.
Because if he doesn't burn off the part of the monster's body, it will soon return back to his body, making it regenerate.
But still, Jia Hao's internal energy was rather limited. And since he used the Crimson Frenzy Blade Art and the robust Metal elemental energy, his energy has been depleting rapidly.
