The Fake Young Master Raises a Child [Book Transmigration]

Only when he was dying did Xie Jingyu realize he had transmigrated, and become a cannon-fodder character in a book who gave the protagonist money and treasures. The book says the protagonist is the son of a government official, while Xie Jingyu is a farmer's son. After an accident, the babies were switched, and Xie Jingyu took the protagonist's identity. Later, the protagonist perseveres, wielding a spirit-spring jade pendant, and returns as a king, forcing the impostor Xie Jingyu to get lost! Xie Jingyu refuses to accept this and causes the protagonist all kinds of trouble, but the protagonist's many admirers beat him so badly he can't fight back. In the end, he dies of poison. When he wakes up again, Xie Jingyu finds himself being denounced by everyone. Xie Jingyu: Fine, I can leave, but that jade pendant was originally mine. Give it back! The protagonist refuses, so Xie Jingyu runs back to his hometown. His mother tells him: The jade pendant is one of a pair. It doesn't matter that the smaller pendant is gone. I'll give you the larger one. And so Xie Jingyu begins a happy life farming, picks up a child, and becomes a village schoolteacher. It's just that... is there something strange about the way this child looks at him? Theme: Raising a child in ancient times
