Before My Baby Was Switched at Birth, the Good-for-Nothing Finally Snapped

【Reborn + Revenge + Face-Slapping】 In his previous life, Xue Mingjie didn't discover that his biological son had died long ago until his entire family was murdered. The boy he'd raised with his own hands and pinned all his hopes on was actually his brother's child. That mad beast had switched the two babies as soon as they were born. He sent the impostor abroad to study and gave him a fortune, while his own son was raised in a cowshed, living worse than an animal, until he was finally beaten to death. Consumed by grief, Xue Mingjie risked his life and took that beast down with him. When he opened his eyes again, he was back on the day his wife gave birth. This time, he watched with a smile as that family brought their misfortune upon themselves.
