It rained at night in the capital city, and the color of blood spread over the glazed tiles of the Jiaofangsi. Jiang Qingqing, the official patrolling the city, cut open the blood talisman in the belly of the snake demon with his sword, but he got a glimpse of the centuries-old secret of the Zhu royal family - Yun Mengze's dragon vein was stolen.
Jiang Qingqing, who has the blood of Shenluojun, and Zhu Meier, the dragon girl, are forced to get involved in this maelstrom of intrigue. The reverse scales on the girl's neck are the key, the broken tiger talisman in his hand is the shackles, and the "Dragon Armor Heavenly Book" frozen deep in Lishan Mountain hides the forbidden technique of reversing the dragon's veins.
On the night of two moons and the same sky, the emperor's corpse wrapped in chains crawled out of the imperial mausoleum, and the resentment of the dragon under the cold pool turned into a skeleton boat. Only then did Jiang Wuqing learn that his father Jiang Qishan's "effort to suppress demons" three years ago was actually a heart-breaking crime: the Zhu family continued to write the fate of the country by using dragons to guard the whole family's flesh and blood, and even trained Xuan Chi Dragon Girl into a formation eye. And the free and uninhibited Thirteenth Prince Zhu Buyu had hidden in his sleeve not only the photo beads, but also a streak of red sun blood pattern that was exactly the same as that of the Evil Yang Society...
When the Suzaku Gate was cracked by Xuan Chi's cold air and the imperial seal collapsed amid the dragon's roar, Jiang Wuqing held Zhu Meier's sloughing hand and finally saw the truth of the bloody words on the brocade handkerchief——
**"On the day when the dragon's veins return to the ruins, all those who steal the secret of heaven will be buried in the secret of heaven."**
In this chess game, the holder was once the pawn, and the dragon slayer eventually became the evil dragon.
Only a young man with a sword, a thought, and a heart full of cold blood dared to ask the glorious way of heaven about right and wrong.
