Fifteen years ago, everyone in the "Tiangong Pavilion" was punished for controlling the taboo Beichen legacy, and the mirror lake was stained with blood. Fifteen years later, Su Yan, a sickly scholar, entered the imperial capital. He was possessed of world-shaking wisdom, but only a broken body was left. His only purpose was to clear up that heinous injustice.
In the turbulent court, he supported the weak King Xiang, and used the astonishing wisdom in the posthumous scrolls to tear apart the enemy's followers while talking and laughing. The general of Qingmei in the past, the guardian hidden in the palace, and even the crazy fellow disciples in the enemy camp are all involved in the web of fate he has laid. When the layers of fog were lifted, the sword of truth finally pointed at the supreme imperial power.
On the Golden Palace, he questioned the emperor with the principles of the stars and judged the past with the way of justice. Although the injustice has been settled, the flames of war are rising again. Faced with the crisis of his family and country, he made the final choice - to burn out the afterglow of his life, illuminate the mountains and rivers with the light of Beichen, and complete the inheritance of a civilization that transcends revenge. This is a story about faith, sacrifice and character. How a person uses wisdom as fire to burn through the night and usher in the dawn.
