Burdened with millions in debt and with his family's old restaurant about to be sealed off, chef Zhao Dong accidentally draws a space-time door leading to the Qin Dynasty. A bowl of oil-splashed noodles makes the Qin people scramble for it in Xianyang; a few Qin coins are calculated by the system to be hundreds or thousands of yuan! Roujiamo, tea eggs, liangpi, and steamed buns take turns appearing, with diners queuing from two people to blocking the street, and eateries expanding from one to two. Zhao Dong also transforms from being cornered by creditors and counting pennies for meals into a debt-cleared, daily-earning over ten thousand great Qin hero, even alerting Qin Shi Huang. However, as business prospers, laws, powerful nobles, and identity crises step by step approach, and Zhao Dong will see how he guards his rice bowl and life between two eras.
