When the Emperor of Dongliang Kingdom was the crown prince, he married the princess of Nanling Kingdom and ascended to the throne with the help of Nanling Kingdom's power. Later, he had an affair with the eldest princess of Dongliang Kingdom and gave birth to Princess Crescent Moon. The queen knew about it and secretly killed the queen. In order to stabilize the throne, he also made peace with the enemy Xiling Kingdom and ceded territory to pay compensation. Su Jingyuan, the Taifu and Chief Minister of the two dynasties, disobeyed in court. The emperor was already wary of the virtuous Taifu, who was full of talents. The eldest prince and his uncle, the military minister Gu Chongshan, framed the virtuous Taifu, collaborated with the enemy and treason, and deceived the public with their lies. This aggravated the emperor's suspicion, and he took the opportunity to kill the Taifu's family on trumped-up charges. The eldest prince Xiao Jingyan took the opportunity to add insult to injury and kill the prince Xiao Jingyu. However, Xiao Jingyu's life should not have been taken. He fell to the bottom of the cliff and was saved by Mr. Yunchen, the old friend of Taifu Su Jingyuan, and Su Wanci, the orphan of the Su family. Seeing the Taifu's family die tragically at the hands of a ruthless emperor, and his brothers' desperate pursuit of him, the prince Xiao Jingyu, who has always been loyal to the emperor, patriotic, considerate of the people, and kind to his courtiers, changed his mind. Mr. Yunchen and Su Wanci stayed by his side to help him achieve nirvana and rebirth. Jamel Xiao used his personal relationship with the eldest princess and Crescent Princess to seduce the emperor of Dongliang Kingdom, seize the imperial power, and try to ascend the throne. With the support of his mother's family, Xiao Jingyu regrouped and returned to Dongliang Imperial City to fight for the throne, restore the Su family's name and bring prosperity to the people. When she returned to the Golden Palace, Princess Xinyue was threatened by the eldest prince Xiao Jingyan and the eldest princess, so she had to stab the prince Xiao Jingyu, whom she had always admired, with a sword. However, after the sword attack, Xiao Jingyu woke up in the ward of a modern hospital.
