"I already told you before, the method is right there in your Heart Lake, yet you keep coming to ask me for it."
The Sword Spirit smirked and said:
"You don't think that all cultivation secrets in the world follow the same pattern, summarized by the predecessors into texts on bamboo slips or jade tubes, exclusively for those novice protagonists in storybooks to comprehend, do you?"
Zhao Rong coughed.
"Back when I slaughtered that strange out-realm martial artist and burned his monstrous and vast-blooded body, I used a secret technique to peer into his indestructible and pure jade-colored skeleton and reverse-engineered a rough cultivation method from it."
"After many observations and incorporating some of my own insights, I carefully modified it to create the peculiar out-realm technique that you're practicing now, suitable for our Xia civilization."
The Sword Spirit seemed mercurial, its mood inexplicably worsening as it spoke.
