Lu Changge, the sixth prince of the Great Xuan Dynasty, is the son of Consort Gu, whose family comes from the Marquis of Zhenbei's household. His mother was framed by the Grand Tutor and the Empress's faction and eventually died of sorrow. The sixth prince appears reckless and dissolute on the surface, but in reality, he conceals his true strength. His beloved elder sister, Princess Zhaohua, Lu Mingyao, was sent to the Langrong Kingdom for a political marriage and returned home dead. Enraged, Lu Changge kills the Langrong envoys and activates the Valiant Immortality System. By bravely forging ahead and righting the world's injustices, he can attain immortality. From then on, he walks a path of survival through death, killing corrupt officials, confronting prefects, executing a prince who sells opium, punishing court officials with his staff, striking down powerful ministers, placing the Empress under house arrest, deposing the Crown Prince, seizing the throne in the Golden Hall, purging traitors from the imperial court, and bringing peace to the four corners of the realm.
