Traveling through the Tang Dynasty for ten years, Lu Qing accumulated ninety-five cases by solving crimes, and was only five cases short of unblocking the cheat. At the beginning, he was imprisoned in Tianlao and forced to marry Princess Changle.

When the illusion of "a fierce ghost seeking his life" was peeled away, the real culprit turned out to be... Your Majesty, I will not marry this consort.
