Wen Kexing, the crown prince of the Xian kingdom, with his silver-white hair; was often seen as bad luck.
As a god, his hair was not supposed to turn white due to his long life. But this wasn't the case for Wen Kexing.
So, you might ask, why can his position as crown prince still be maintained until now? Eventhough he didn't want to be crown prince anymore because he had received too much humiliation from the emperor, his father himself.
To give his little wife, Zhou Zishu, a better life.
Wen Kexing died on the mountain. The now immortal Zhou Zishu was left in that cold armory all by himself...until a thousand years later, a man appeared on the mountain who looked exactly like Wen Kexing.
A canon divergence/alternate universe where Wen Kexing reincarnated into Gong Jun, but Zhou Zishu remained the same as he was in the past.
