The emperor's imperial edict to return to Beijing to receive a reward made it clear that the situation was a dead end. He simply led eight hundred heavily armored cavalry straight into the Jinluan Palace, with his long sword pointed directly at the emperor's neck. Unexpectedly, when he was about to die, the emperor actually took out a bag of Liqun! A time-travel code crossed each other, and the two of them turned out to be childhood friends who had passed away in the past. And the person who killed them both traveled through time together and hid in the palace.
