Destroying My Sect Gets Me Back to Blue Star? Bro, You Should've Said So!

[Dual-world travel + brothers turn into mortal enemies + supreme leaders of the righteous and demonic paths + flipping the table all the way + satisfying power fantasy] “Chu Kuang, your sins are unforgivable. Today is the day you die.” “Gu Changsheng, even if I die, I'll knock out two of your teeth!” The final battle between the righteous and demonic paths. The Immortal Sword of Longevity, Gu Changsheng, and the Nine Nether Demon Venerable, Chu Kuang, fought fiercely for three days and three nights. Just as they were about to settle things once and for all, two characters suddenly appeared on the life-saving treasure Chu Kuang had pulled out. [Blue Star] Gu Changsheng: “A bottle of palace jade liquor?” Chu Kuang: “One hundred and eighty a glass?” “You're freaking Gu Yan?!” “You're Chu Ye?!” The two sworn enemies who had spent eight hundred years trying to kill each other completely lost it on the spot. Then Chu Kuang told Gu Changsheng something else. Eight hundred years had passed in the Nine Heavens Realm. On Blue Star, only eight months had gone by. Their parents were still at the hospital, waiting for the two “coma patients” to wake up. Gu Changsheng: “Is it hard to get back?” Chu Kuang: “Extremely! Each of us would have to wipe out at least ten ancient sects!” Gu Changsheng: “...” Chu Kuang: “Why aren't you saying anything?” Gu Changsheng pulled out a map. “I was thinking about which twenty to wipe out first.” Chu Kuang: “???” Nine Nether Demon Palace. Chu Kuang: “This is my home!” Gu Changsheng: “Which makes it convenient.” Taiyi Sect. Chu Kuang: “Their sect master just saved your life!” Gu Changsheng: “Which means they'll trust me.” Danding Sect. Chu Kuang: “Why is this one marked too?” Gu Changsheng: “They're rich.” At that moment, Chu Kuang finally understood. Being a Demon Venerable was just a job. A man like Gu Changsheng... now that was a professional.
