Freshly graduated Huajuan inherits her grandfather's rundown snack shop, which surprisingly connects to ancient times at midnight! Relying on modern delicacies like instant noodles, milk tea, and hot pot, she conquers the taste buds of the ancients, trading them for massive amounts of silver ingots and peerless antiques to easily get rich and make a comeback in modern times. Leveraging opportunities from both realms, Huajuan not only uses ancient rare artifacts to fiercely slap her former bullying and vicious classmate, but also heals the war-damaged, anorexia-suffering iron-blooded general Lu Mingli in the ancient era, redeems the suffering girl Huasheng, and finally opens Huajuan Embroidery Workshop to grow bigger and stronger, taking in refugees to build Nianhua Village. A single midnight snack shop opens up a miraculous journey of sudden wealth and healing.
