San Lang used to be a modern young adult, who transmigrated into a book about a two faced emperor who mentally tortured a kid, "White robed emperor", and he had only read the whole thing in hope that said kid, Xie Lian, would win, but he didn't.
He transmigrated as this young boy he knew would grow up to be a general of Xianle, die in the war, and after trying to fight bai wuxiang as a ghost, he would be killed by Xie Lian, after the emperor promised that by killing this ghost, Xie Lian could ascend a second time. Promise which was never fulfilled.
Anyways, our San lang, now called Hong'er, wasn't strong like the original, He was used to being pampered by his rich family who owned a gambler's dem. And suddenly so much abuse by his new "family" destroyed his mental health.
So he decided to jump off a building in the middle of a festival, knowing that he'd probably ruin it but not caring.
The system screamed "OOC" but he laughed "what are you going to do about it? Kill me?"
But after jumping, instead of hitting the cold hard floor, he fell into someone's embrace, and looked up to see a mask falling to reveal the crown prince of Xianle, Xie lian.
