In 9016, astronomers discovered traces of two male lifeforms on the moon S/9010+X2, orbiting the planet Kuichou in the Difang system, 9.5021×10^3241011813 kilometers from Earth. They were named Zhen and Yan, respectively. According to reports, Yan was the supreme ruler of S/9016+X2. Zhen was suspected to have come from Kuichou, which had been completely destroyed by an unknown disaster three hundred years earlier. He also shared a name with the former ruler's eldest legitimate son, and his face was a 99.9% match. But in the Kuichou system, where cloning was widespread, there was no way to verify whether this Zhen was the same person as that Zhen. A childhood romance caught up in a power struggle; a love and hate entanglement over whether to destroy the world or save it. A century later, Zhen alone can see humanity's fate. Does he want to be Zhen, with supreme power in his grasp, or the young man who fell in love with Yan after entering the planet's core for three hundred years?
