Xu Guang closed his eyes, stretched out his left hand, and according to the mantra, for the first time truly felt what was transforming the demon in the Void Realm.
This is a power completely different from Source Qi and Spirit Charm, more sinister, like... a Fierce Ghost.
"If that's the case, then by continuously bathing in the blood of different types of demons, it should be possible to accelerate the cultivation of this Secret Technique."
Xu Guang had an epiphany.
...
Half a month later.
The Hall of Merits in the Demon-Slaying Academy.
The Elder of Merits looked to be a man around thirty years old, not handsome, but rather, with a long scar across the middle of his face, giving off a fierce and intimidating appearance.
"You want to go to Penglai?"
Xu Guang nodded, "I have a friend who said that a Secret Realm is opening there and invited me to enter together."
