At 9:03 a. M., In the back kitchen of the "Cloud Realm" restaurant on the 45th floor of Shanghai's Lujiazui World Financial Center, the ventilation system was still humming to dispel the residual smell of disinfectant water from last night's cleaning. Bian Aike was already standing in front of the cold storage. He is wearing a custom-made white chef uniform with a low-key silver flame pattern embroidered on the cuffs - this is the logo of the top manager of the "Yunjing" kitchen, and it is also a medal earned by him after twenty years of working in the industry.
