Ten years later, upon being resurrected, he discovers that his formerly obedient and virtuous disciple has become the ultimate demon lord! "Yinli, show more reverence towards me, your master!" "It's because you're my master that I want to engage in technique discussions with you like this..." The original webcomic is available, as are official translations.
