Lin Feng, a modern deliveryman, was electrocuted on a rainy day and traveled to the outskirts of Chang'an in the early years of Zhenguan. When he first entered a different world, he was penniless and encountered gangsters. He escaped with the help of modern fighting skills. While doing manual labor to make a living, he discovered the pain points of Datang's single food and backward transaction model. He used simple tools to make "secret kebabs" to earn his first pot of gold. He met blacksmith Wang Daniu and orphan Su Waner, formed a preliminary entrepreneurial team and established a foothold in the suburbs.
