They were born connected by blood, but they were destined to face each other with swords. The Ling family, an ancient family of cultivation, gave birth to a pair of twins: the elder brother, Ling Yun, possesses the "Holy Body of Chaos" and has been cultivating for thousands of miles, but is as silent as iron due to the pain of tearing his meridians; the younger brother, Ling Feng, has mediocre qualifications and relies entirely on the mysterious system to redeem his cultivation. He relies on a clever mouth to gain favor. The two hate each other-- Ling Yun hates his brother for being opportunistic: "The system is poison and will eventually bite back!" Ling Feng ridiculed his elder brother's stubbornness: "It's better to practice hard for a hundred years than I can earn gold in three days!" Until the night when the family was exterminated, the blood of the parents was splashed on the altar. In order to track down the blood feud in Nether Palace, the brothers were forced to exchange identities: **Ling Yun was trapped in his brother's waste body and was ridiculed by the system: "99% of the meridians are blocked, it is recommended to give up treatment"; Ling Feng took the place of his brother's holy body, and was driven crazy by the pain of cracking his meridians: "How did this lunatic survive to this day?!" ** And when Ling Feng used his brother's body to practice evil skills, Ling Yun used the system to use his sword intent wildly-- The Lord of the Nether Palace suddenly discovered that the "Heart Corroding Gu" he had planted with his own hands was violently backfired by the resonance of his two souls! "Do you think the exchange is a ploy?" A sneer came from the blood mist on the altar, "No, this is a heart-breaking tactic specially made for the twins!"
