A First-Rank Demon Husband

She's a loose immortal who has failed all ninety-nine of her tribulations, and ends up transmigrating into the body of a good-for-nothing young lady. He's a walking disaster, born under an ill-starred fate. Anyone who gets near him is bound to meet with disaster within the time it takes an incense stick to burn. Since we're both so miserable, why don't we get married and join forces to turn the whole world upside down!
