After My Engagement Was Called Off, I Trained for Ten Years and Became Unbeatable

Ten years ago, he was the family's good-for-nothing young master. A genius beauty broke off their engagement, and his family cast him aside without mercy. Ten years later, he is a battle-hardened Hidden Dragon general and the one and only cultivation expert on Earth. Ancient medicine, alchemy and pharmaceuticals, artifact forging and talisman crafting, feng shui and fortune-telling, as well as esoteric arts and martial techniques are all within his grasp. In search of cultivation resources, he is ordered to protect a stunning CEO. But the genius beauty who broke off their engagement ten years ago turns out to be the CEO's closest friend, and she's hopelessly fallen for him! Now he's got a headache. His former fiancée is so devastatingly beautiful that she could bring a nation to ruin. Should he let bygones be bygones and take her back? Or should he coldly reject her and make her regret it for the rest of her life?
