Han Jing did not understand and asked, "What use is it?"
Xia Wu explained, "There is a special passage on Minghan Island that leads to the Upper Three Realms, but not just anyone can open it. It requires special permission. Each major family in the Upper Three Realms has its own emblem, and with this emblem, they can directly access five regions. Of course, this passage is directional; within the thirty-two Islands of the Human Domain, there are only three passages. One is on Minghan Island, another on Yunzhu Island, and another on Yue Guang Island. However, once you arrive in the Upper Three Realms, with fewer islands there, one doesn't need to wait as long as in the Lower Three Domains. Special passages allow easy travel between islands. So, as long as you use the emblem Xiaoqi gave you to open the passage to the Upper Three Realms, we can head directly to Leiguang Island."
