Tianmang Shines on Mountains and Rivers

In the thirteenth year of Yongle in the Ming Dynasty, the world was undercurrent and the imperial power was not stable. After the mysterious death of his mentor, Gu Linyuan, a disciple of the Zoroastrian Orthodox Church, was poisoned with the mysterious poison "Seven Star Begonia" without any cure. He was also hunted down by the imperial court and unknown forces. On the way to escape, he was forced to go with Shen Qingyue, the Jin Yiwei secret agent who was ordered to seize the sword, but unexpectedly discovered that she was carrying a Zoroastrian saint token that had been missing for many years, and her life experience was a mystery. An ancient evil "Sword of Heaven" that backfires on the sword holder, a pair of "Sun and Moon Jue" related to the thousand-year secrets of Zoroastrianism, and a "Dragon Vein Diagram" that can shake the world's energy, tightly bind the fate of the two. From the misty rain in the south of the Yangtze River to the roaring waves of the South China Sea, from the poisonous traces of the Miao border to the yellow sand of the Western Regions, they are forced to be involved in a grand chess game that spans thousands of miles and connects the government and the public. The remains of Jianwen, Zheng He's treasure ship, Persian heresy, the forbidden technique of burning one's body... Under layers of fog, is the ultimate struggle for the true meaning of "light". This is a desperate journey to find a way to survive in the cracks of history, and it is also a profound inquiry into the nature of faith and power. When the dark fire comes from the east and the stars are about to appear, can they cleanse the evil spirit on the sword, heal the illness in the body, and light up an immortal light in this chaotic mountain and river in the darkest moment?
