Before the ancestor entered seclusion, he left the lost secret technique of the Joyful Chan to Gu Yao. "If you can cultivate with a Mahayana stage practitioner, you can form a golden core in ten years and ascend to divinity in a hundred!" But there are only two Mahayana practitioners in the entire cultivation world. One is a vile old man from the demonic path in his twilight years, with a sinister nature who enjoys turning people into oil lamps. The other is the sect leader of a top-tier upper realm sect, Rong Ji—a sword cultivator who practices the path of ruthlessness, rumored to be even more brutal and cruel than the demonic old man! Gu Yao accidentally entered Rong Ji's pocket dimension, transformed into a small fox, and was picked up by the amnesiac Sect Leader Rong, who was there to cultivate his heart. The little fox was freezing, and seeing that Rong Ji was about to eat him, it whimpered pitifully and begged for mercy. "...Never mind, I won’t kill today. Go sleep on that cushion." A hundred years passed in a flash, but only one year had passed in the real world. Unexpectedly, enemies caught up, and Gu Yao quickly packed up and fled. Soon, news spread that Sect Leader Rong had emerged from seclusion, offering a heavy reward for the capture of a fox demon! Gu Yao tucked his fox tail tightly: What’s the reward? What? Say it again?? A million spirit stones?!?! Gu Yao: QAQ Can I turn myself in for the reward??? In short, the bottom transforms into his original form and enters the top's heart-cultivation world, spending a hundred years with the top who has lost his memory.
