The red light appears in Dangshan Mountain, and the blue dragon rises in Bian River. In the troubled times of the late Tang Dynasty, thousands of miles away from starvation, Zhu Wen, a rogue who was predicted to be "rich in thirty years and poor in fifty", went from being a brave general under Huang Chao's tent to being a "loyal" hero in the Tang Dynasty. In the end, he wore a dragon robe and personally buried the three hundred years of the Tang Dynasty. He is good at accepting advice and encouraging farmers and mulberry trees. He also kills kings and slaughters cities. He throws himself into the turbid current at the White Horse Post. He favors counselors and loves his old tribe. He is also suspicious of tyranny and sleeps with a knife on his back. Secrets of unofficial history are intertwined with the light of official history: the beggar's gift of a bowl hides the emperor's prophecy, the sound of God's sword warns of a massacre, Mani's magic spawns the will to usurp the country, and the treasures in the underground palace bury the mystery of the rise and fall. This is the cruel tear between humanity and ambition of a generation of heroes. It is also an epic of a soul in troubled times who betrayed everything and was betrayed by fate in the bloody setting sun.
