Lin Yixin, the daughter of the richest man in Yangzhou, Dajing, relied on her extraordinary business acumen to protect her family's business, but was assassinated and traveled to modern times. She was rescued by Jiang Xiaoxiao, who was living under the shelter of someone else, and the two became close friends.
In order to gain a foothold, Lin Yixin used the wisdom of ancient merchants to develop ancient sauces and stalls, and gradually established "Yixin Xiaozhu". During this period, she met President Wan Bai, who had an inexplicable affinity for her - she was the reincarnation of "Mr. Baizhou" who was engaged in her previous life, and she had a deep fateful bond.
There are many dangers on the road to starting a business: Jiang Xiaoxiao's foster family makes things difficult, peers suppress him, the descendants of his ancient enemies Liu family take revenge, and it also involves time and space secrets such as the time and space jade pendant and the boundary stone. Lin Yixin combines ancient business strategy with modern thinking, and joins forces with allies such as Su Manni (a descendant of the time traveler), Liu Ruoxi (a descendant of the Liu family), Tao Tao (a descendant of the Lin family's maid), to break the conspiracy, resist the "lawful" organization, and repair the gaps in ancient and modern trade routes.
As the memories of Wan Bai's past life are revived, their relationship heats up and they share the mission of "guarding time and space". Lin Yixin not only counterattacked and became a modern entrepreneur, but also built an "ancient and modern information bridge" to integrate ancient techniques and modern civilization and promote cultural inheritance. In the end, she maintained the balance of time and space, continued her family's business, and gained a love that spanned thousands of years, composing the legend of "the hairpins are exchanged for neon lights, and the trade routes connect ancient and modern times".
