The King of the Underworld Pursues His Wife, but His Little Princess Only Wants to Earn Merit

What's it like to have the skinflint King of the Underworld hound you every day to repay your debt? Mu Nanxi just wants to throw her head back and roar, “This damn world can go to hell! I'm done playing!” But if she gives up, she'll be struck by heavenly lightning. She has no choice but to roll up her sleeves and get to work. Reading faces and telling fortunes, catching ghosts and banishing evil, feng shui and geomancy, refining medicine and capturing demons... As her merit steadily accumulates and the restoration of the Shanhe Token seems within reach, she suddenly realizes... she may have accidentally walked right into someone's trap! ...Knowing that the little girl is focused on earning merit, a certain someone possesses an ordinary mortal whose merit is so abundant it could forge a golden body. At first, he puts on a pitiful act, pretending to be plagued by evil spirits. “Master, will you save me?” Mu Nanxi's heart softens. “All right.” Later, he parts with a little of his merit. “Little girl, I'll give you my merit. What will you give me?” Mu Nanxi hesitates for a few seconds. “I'll resist temptation, starting with myself!” Then he brings out a ten-thousand-year-old demon core, the key to restoring the Shanhe Token. Mu Nanxi cries, “I can't refuse this! There's absolutely no way I can refuse!”
