There were a few urban novel protagonists who became invincible after being dumped by their girlfriends. I recommend the following: Golden Pupils, My Divine Domination System, Supreme Super Expert, Free Farmer, Godly Tycoon: The Bull I Bragged About Can Come True, My Rich Lady, The City's Top Medical Saint, Rebirth 99: Wealth Begins from the stock market, My Business Journey, My Beautiful CEO, and Invincible Fitness Master. I hope you like my recommendation. Muah ~
