Datang: at the Beginning, Li Er Was Asked to Go Hiking

In a parallel time and space, Xia Feng, who traveled through time, didn't understand what was going on, but was dragged to be a substitute because he looked too much like Li Er. After the Xuanwumen Incident, Xia Feng had already realized that this guy would definitely burn bridges. Xia Feng: "Your Highness, before I die, I want to see the great rivers and mountains."

But when he descended the mountain without any obstacles, he realized that there was a serious problem. At night, who sleeps on the left with Changsun Wujia... And who sleeps on the right...
