Disowned by Everyone, Hated by All, I Became the Slap God of War

[Transmigration + face-slapping + subverting expectations + feel-good story] Xiao Yang transmigrated into the body of a rich young master, only to be treated unfairly. His family favored their adopted son, Zhao Lin, and treated Xiao Yang like a servant in his own home. In this life, Xiao Yang came to his senses. He would never again be anyone’s servant, and only wanted to stand tall and live with dignity. After receiving an order from the System, he gained the power of a brawler and became the Slap God. To live freely and on his own terms, he turned into a rebellious brat who cared for no one. He beat every member of his family, yet they insisted on clinging to him and fawning over him. Once, they could hardly be bothered with him. Now, he was someone they could never hope to measure up to.
