There have been a lot of things going on in Nanyang Prince's Mansion recently.
First, the prince traveled thousands of miles to wipe out the Nether Sect on Dugu Peak, and the leader of the Nether Sect, the Red Devil, disappeared without a trace. The emperor granted her a marriage, and the bride was the daughter of the current imperial master. On the same day, the prince was overjoyed, but he was interrogating a traitor from the demon sect.
Bizarre things happen one after another. Who is the real murderer behind the scenes? And where did the demon leader of the demon sect escape to?
