The Mysterious Merchant Alliance indeed had long-standing connections with Tianyuan City.
The owner of the Mysterious Shop was once the mysterious merchant, now a high-ranking member of the Merchant Alliance, 'Qiye'.
Qiye is now the general manager of the Mysterious Merchant Alliance in the countries of Tai Xuan and Shen Yao, but he still prefers to reside in the main store in Tianyuan City, selling some mysterious goods.
The reason the 'main store' is located in the depths of an alley, with a plain and unassuming appearance, is to adhere to the mysterious principles of their alliance.
This Mysterious Shop is not built in a fixed location, but 'refreshes' at random spots within the non-restricted areas of Tianyuan City's circle.
It leverages some great forces of Tianyuan City to allow Qiye to better embody the mysterious path.
Of course, with the national main store of the Mysterious Shop, many powerful individuals often come here specifically for it.
