What to Do After Becoming the Villain from the Start

Chen Hao transmigrated into a novel about a domineering hero. From the start, he offended the protagonist, Dragon King Lin Luo. He went from living in fear to binding himself to a Villain System and sweeping aside all opposition. The protagonist has a sister? And she's not even his biological sister? The villain says, "I'll take care of her." What? He also has a fiancée? No problem, leave her to me. Heh heh heh. What should he do when the protagonist breaks down? Oh well, it can't be helped. This generation's Dragon King is just too weak. Your villain hasn't even gotten started.
