It has been more than a month since Yang Yun and Mingyue returned to the place they belong to. It also meant that his friend, Li Ran has been missing for more than a month. The last time Xue Yi Ming saw Li Ran, they were in the mountain, sending off Yang Yun and Mingyue as they opened up the portal that led them back home.
At that time, a strong wind blew over, and for a moment, both Xue Yi Ming and Lin Tian Yu had their eyes closed. When they opened up their eyes again, Yang Yun, Mingyue, and Xiao Mi were no longer around. Strangely, his friend, Li Ran, had also vanished.
Xue Yi Ming and Lin Tian Yu spent a day looking for Li Ran before they decided to report him as missing. General Lin then dispatched a few of his soldiers to help to look for Li Ran. After a week with no lead and result, they decided to pull back their search and rescue mission. It took a while before Xue Yi Ming could accept that his friend had probably entered the portal accidentally.
