He couldn't gauge Li Chang'an's exact level of Cultivation.
But he was certain of one thing.
For Li Chang'an to have so easily slain a Celestial Pride like Fan Yunfei, he was most likely not far from Core Formation.
Xiao Haoran reminded him, "If you're going to attempt Core Formation, you should find a way to kill Xiahou Hong first. I'm worried he has become your Heart Demon, even if you haven't realized it yourself."
"Him? A Heart Demon?"
Li Chang'an couldn't help but laugh.
Xiao Haoran's concern did have some merit.
After all, back at his Foundation Establishment Ceremony, at the height of his glory, he had been suddenly and forcefully humiliated by Xiahou Hong.
Anyone else in his shoes might truly have developed a Heart Demon from the experience.
But Li Chang'an's mindset was remarkably stable.
"Don't worry, Daoist Xiao. That man is not enough to become my Heart Demon. After I reach Core Formation, I will slay him openly and honorably!"
