The box Ye Qingmei left behind contained a sniper rifle (or a crossbow, depending on the version), letters for Wu Zhu and Fan Xian, and abortion medicine for Fan Xian. This box was the whereabouts that the Overwatch Council had been searching for. The Qing Emperor sending people to search for the box might have something to do with the things inside. After Fan Xian opened the box, he found a heavy sniper rifle (or crossbow) and a letter inside. This letter revealed the mystery of Fan Xian's past, confirmed that Ye Qingmei was a transmigrator, and displayed her extraordinary ability and brave actions. The reason why Ye Qingmei left this box behind was probably to provide protection for her child and to leave behind her last bit of love.
