Ji Wuming glanced at Ling Han before shaking his head, and replying, "What if I told you that the Severing Mundane Tier, Dividing Soul Tier, Celestial Path, and whatnot all didn't exist before? These notions only appeared after the transformation of heaven and earth. How would you react?"
Ling Han's mouth was slightly agape, and he said in astonishment, "I'll probably react like this."
Ji Wuming nodded, and said, "A long, long time ago, the Celestial Path didn't exist."
In other words, in Ji Wuming's previous life—that was when he was the Nine Lights Ancient Buddha—there was no need to traverse the Celestial Path to become a Celestial King. Instead, they used another method to form their Celestial Seed.
