After Being Sent to the Frontier, the Wangfu Family Knelt Down and Begged Me for Forgiveness.

Lin Yuan had been the young prince of Zhenbeihou for more than ten years, but he was suddenly told that he was a fake. His parents and sister, who he loved so much, said that the palace was still his home and would love him as much as before... But as soon as he turned around, he asked Lin Yuan to take the blame for the real young prince, exiled to the frontier, and ignored him. Five years of hellish training made Lin Yuan see everything clearly! Don't persuade others to do good without going through their suffering. A few years later, everyone knelt in front of Lin Yuan and begged him for forgiveness.
