The Master Comes Down the Mountain: the Engagement Was Annulled by the Goddess of War at the Beginning

We were in the city, and just after we got off the mountain, my soon-to-be fiancée used the strength of the first female war goddess in the Dragon Kingdom to make me give up. How should I tell her that I am more than a hundred times more powerful? There was a bad guy who wanted to compete with me, and I accidentally beat him to death. Fortunately, I was able to save him with my superb medical skills. But the number of people who came to me for treatment increased a hundred times, and they were all rich and powerful people. Now the matter has become big, how should I end it? Waiting online, urgent!
