Yang Ling clearly remembered obtaining the Vajra White Bone Wisdom King Art at the Great Nether Temple.
At the time, the system had informed him that he had gained the Vajra White Bone Buddha's approval.
So... the White Bone Master suffered a backlash after failing to cultivate this art because he hadn't gained approval?
"White Bone God Lord, are you saying you suffered a backlash while cultivating the complete White Bone Primordial Spirit Method?"
Ji Tianming was somewhat shocked. "You're clearly an expert in this path, and the lord of the White Bone Cave. Surely your White Bone Primordial Spirit Method has already reached the Divine Path Realm.
"Why would you still suffer a backlash while cultivating the complete White Bone Primordial Spirit Method?"
Zhao De looked thoughtful, his gaze suddenly falling on the statue of the Bone Emperor.
"Because you didn't gain the Bone Emperor's approval?"
"The Bone Emperor's approval? Why would you need anyone's approval?"
Ji Tianming asked instinctively.
To his surprise, the White Bone God Lord nodded slightly.
"Indeed, I suffered a backlash from this method because I hadn't gained approval."
"But not the Bone Emperor's. Our sect's legacy did not originate with him."
"Not the Bone Emperor?"
This time, it was Zhao De's turn to frown.
The more Ji Tianming heard, the more confused he became.
"What are you two being so cryptic about? Whose approval could you possibly need to cultivate an art?"
"Beyond first-rate arts differ from other arts. They come with extremely stringent restrictions."
Zhao De explained, "Put simply, you need the approval of the founding patriarch who created the art before you're qualified to cultivate it.
"Otherwise, forcing yourself to cultivate it will only result in a backlash, just as it did for the White Bone God Lord."
"That's actually a thing?"
