First of all, Fang Jinyu had to master all ten of the "Qing Fu series" secret techniques before he could cultivate the secret technique that was especially used for strengthening techniques!
Fang Jinyu cursed in his heart.
"Mother, you haven't cultivated yet?"
Qing Fu blinked her eyes, revealing a look of realization.
However, Qing Fu then narrowed her big black and white eyes, and the corners of her small mouth curled up slightly. She continued and said, "Mother, if you agree to help me in the immortal realm in the future, I'll teach you a secret technique! As long as you cultivate it to the beginner level, not to mention the devil's intent, you can even be immune to all damage or reduce the damage you receive by half from an Incarnation stage cultivator's attack!"
"No problem!" Fang Jinyu agreed immediately. Since they had met "Qingxian" together before, the little girl also knew that he had been admitted as an immortal official.
