Chen Feifan was a down-and-out cultivator in the mortal realm. He unexpectedly awakened the twin origins of ice and fire, only to be coveted by his sect and betrayed by his fellow disciples. After narrowly escaping death, he gained an ancient inheritance that could sever the heavens. He traversed secret realms across the heavens, refined treasures of ice and fire, and forged twin Dao foundations. He slew his enemies, unraveled conspiracies, and used the power of ice and fire to crush demons in the war between immortals and devils. Wielding the Law of Heaven-Splitting, he rose against all odds to the pinnacle of the immortal realm, ultimately becoming the Supreme Heaven-Splitter and establishing order across the Three Realms.
