Ling Zhige defected because he discovered that his master was feeding the "Tripod of Destiny" with the essence and blood of his disciples. The concentric curse seal of Ying Huai is actually an ancient forbidden technique, which can convert damage into spiritual power supply. When the master forced Yinghuai to torture Ling Zhige with a curse seal to force him to confess, the curse seal diverted the master's attack to himself! The truth is revealed: Yinghuai is the incarnation of the artifact spirit of the Tianming Cauldron, and Ling Zhige was the immortal king who sealed the cauldron spirit in his previous life. In the end, Ling Zhige crushed his natal sword and inserted it into the cauldron. The lingering curse seal turned into a golden rope and bound him into reincarnation: "This time, I will bind you, forever."
