Si Nan: Wonderful Mechanisms Volume 1

The crown prince Zhu Yuheng has received a sentence known only to him: an unknown poison is slowly killing him, leaving him with just one year to live. Yuheng hides his poisoning and begins his own investigation into the fire that destroyed the greatest palace of the empire in a single night. In the charred ruins, the prince finds a mechanical dragonfly and realizes – this was not an accident, but a meticulously planned crime. The clues lead him to A-Nan, whose hair shines with an exact copy of the dragonfly he found. The meeting between the prince and the girl ends... in defeat. And now the crown prince of the empire is a servant for twelve months. For all the time he has left. And the real enemy still hides in the shadows. It is unknown whose hand set the mechanism of death in motion.
