[System Space + Officer Sister + Face-Slapping and Punishing Scum, Never Taking Abuse]
In his previous life, Xu Yifan married into Ye Meiling's family. He dutifully worked himself to the bone and honored his in-laws, and put both of his sisters-in-law through college. Only when he was old did he discover that the son and daughter he had raised were not his, and that Ye Meiling had agreed to marry him because she was pregnant with her first love's child. Her whole family had deceived him into slaving away for them, taken every last penny he had, and then kicked him out. They wouldn't leave him a way to live? Then they'd all die together!
When Xu Yifan opened his eyes again, he had returned to the eve of his family's ruin. His parents were still alive, and his sisters were safe. This time, he would protect his family, use his space System to build a fortune, and marry a beautiful officer.
His grandparents favored his uncle's family? They used filial piety to stop him from splitting the household? Then he'd beat them until they begged to separate! He'd fight his peers openly and beat the elders with sacks over their heads!
Several families schemed to marry his sister off to a fool for an exorbitant bride price. They dared scheme against his sister, so he'd scheme against their daughters! They wouldn't know how much it hurt until the knife cut their own flesh. Let's see if those families could still get along after turning on one another. It would be quite a show.
And Ye Meiling? Her pregnancy was wonderful news, so of course he'd announce it to everyone! In those days, an unmarried pregnancy was a disgrace, and her two younger sisters wouldn't escape the fallout either. That family of ungrateful wolves could go bother their sister's first love! They should stay together forever and never split up. That family of backstabbers was a force to be reckoned with. They'd always dreamed of marrying into their first love's family, but their lives there turned into a complete mess.
