The Male Lead Transmigrates to the Han Dynasty as Liu Zhi and Liu Bang's Son, and Liu Ying's Younger Brother

I remember that in the first chapter, the male lead was a little boy who hugged Lü Zhi and cried, wiping his tears and snot all over her. Lü Zhi tricked him into going to find Liu Bang, who beat him up. Later, he rebelled against Liu Ying, with Liu Ying's consent, and became emperor. Lü Zhi actually loved the boy very much.
