Datang: Set up a Street Stall to Sell Facial Masks at the Beginning

Yang Mingyuan held up a glass petri dish that was slightly rough but still hundreds of years ahead of the manufacturing technology of this era, and carefully shouted something. "System, apply for acceptance." [Ding! Ingredient analysis is in progress, please wait! [The current properties of the petri dish are as follows: hyaluronic acid (microbial fermentation method), purity 0.1%, Which has reached human body absorption standards! [Congratulations on completing the system test task: making hyaluronic acid! [You have successfully started the life-related continuous mission: the first step of loving beauty! [Please use hyaluronic acid to make facial masks and sell them successfully. The profit will be no less than one thousand gold! [You have obtained the auxiliary book "The Process of Facial Mask"] A series of prompts sounded in Yang Mingyuan's mind, making him feel happy and sad, and he embarked on the road of setting up a street stall to create the most powerful Tang Dynasty.
