Cut Ties, Got a Dragon Queen!

Fifty Daxia coins was what the contract cost at the Abyss trading floor. The buyer got a silver dragon woman of epic rank, fouled by the Abyss and shunned by everyone, and the crowd told him he had wasted his one class change on a burden nobody wanted. He had crossed into that martial world from somewhere else and woken with a system that let him change class. Before anything else he cut off the campus beauty who had lived off him for three years. The class he took was charm tamer, hidden, SSS rank, the only one of its kind. His own talent was purification at god rank, and he used it on the dragon woman until the Abyss was out of her. The two of them hunted, levelled, opened a second class and put a fallen angel under contract. The ones who had laughed at him were dealt with one at a time. As he got stronger, what had happened to his parents years before started coming up.
