Chen Yang traveled through the parallel world and became the only descendant of the Heavenly Master of Qingyun Temple! Disciple: Master is not fully clothed and has a skinny figure. He must be undernourished... He is a peerless expert! Chen Yang: I just traveled through time. I haven't eaten rice for three days and I'm about to starve to death. What a master! Disciple: Master, the techniques you teach are unheard of and unfathomable. They are truly mysterious and profound! Chen Yang: I just made it up casually, wait a minute! You've actually done it all? !
