Nantang was a poor little boy who grew up in an orphanage. That orphanage was an important base for child trafficking. Nantang was unlucky to be chosen, but luckily he was saved by a big brother... This Gu Yan is not the other Gu Yan. He was Nantang before his rebirth. Once he was reborn, he wanted to save himself as a child and let himself suffer inhuman torture.
Intention: I save myself
