You Proposed Breaking Off the Engagement. Is It Reasonable for Me to Exterminate the Clan?

As soon as he woke up, Lu Changge found that he had traveled through time and came to a fantasy world. Become the heir apparent of an ancient family, with a respected status and unparalleled talent. He is the proud son of heaven in the true sense. But due to this identity, he fell in love with the eldest lady of a third-rate family, and was willing to become her lover. Not only did she respond to her requests, but after being rejected ninety-nine times in a row, my predecessor not only did not wake up, but also enjoyed it. Is it reasonable? Totally unreasonable. What's even more disgusting is that the other party took the initiative to break off the engagement at the same time. They actually wanted to swallow the betrothal gift, thinking that if they gave it to them, it was theirs, and they would not pay it back. Lu Changge was extremely contemptuous and had no intention of talking nonsense, and was ready to crush him to death. But suddenly I discovered that my ex liked a woman. She is actually a lucky heroine. Wait, I also have a golden finger specially designed to deal with the protagonist? This is the rhythm of being a villain, okay, okay, things are starting to get interesting. Lu Changge immediately became interested. Since you proposed to break off the engagement, then I would exterminate the clan. Is this reasonable?
