The Gluttonous Master's Little Troublemaker

A shameless, all-powerful, foodie master + X a cute, bashful foodie disciple who turns into smoke whenever he gets embarrassed ***(Modern setting) One day, an uninvited guest showed up in the underworld. He was neither human nor demon, neither soul nor ghost, neither monster nor spirit. Without saying a word, he took over the underworld's frying cauldron and started deep-frying little ghosts to eat. The King of Hell threw all his power at him and still couldn't do a thing, so in the end he had to lure the intruder with food and summon Han Zong, who could handle anything, to deal with him. "Little thing, you've got quite an appetite. I like you. Follow me from now on." "Old thing, do you provide meals?" Han Zong smiled without answering. From then on, he had a little shadow following him around. "Old thing, everyone else has a name. Give me one too, okay?" "What's the point of a name? Can you eat it?" Han Zong smiled and patted his head. "And call me old thing one more time, and I'll cut out your tongue and rinse it in lava before I eat it." "Then what should I call you?" "Master." The little thing knew nothing about this master. All he knew was that Master was even stronger than him and even better at eating. His master could transmigrate through time and space. When he had nothing to do, and was in the mood, he also took on the odd job of guiding the dead who hadn't yet passed on, along with lonely ghosts. This master was sharp-tongued, wouldn't even bother to give him a name, and was always eating by himself. But sometimes Master was very nice too... For example, that day, Han Zong smiled and stroked his head. "Little thing, it's your thousandth birthday today. I'll take you to the underworld to eat deep-fried little ghosts." Master taught him all sorts of things, too... "Little thing, your mouth can't be used just for eating and talking. You should use it to interact with Master more." "Master, what's interacting?" "Come here. I'll demonstrate first." The little thing obediently flew over to his master. Han Zong kissed his little mouth and only let go after a long while. Smiling, he whispered in his ear: "Your turn." As soon as Master said that, the little thing instantly vanished into a wisp of pale smoke. Han Zong: ??? Then the little thing's voice came from somewhere: "Master, I'm going to kiss you now." As soon as he finished speaking, Han Zong felt a cool touch against his lips. Only later did Han Zong realize that his little thing turned into smoke whenever he got embarrassed. Theme: A series of wondrous tales
