The episode opens with Gu Ran, a top master hiding his identity as a deliveryman, learning that his wife Liu Ruoxuan's family will be in charge of the surrender ceremony for the "Four Realms Demon Lord," someone he has been secretly helping. He mistakenly believes this is Chen Qinglan, the female Martial Venerable, repaying him and happily prepares to go home to celebrate with his wife. However, when he arrives home with roses, he walks in on his wife Liu Ruoxuan and the wealthy young man Qin Feng in an intimate embrace. Qin Feng immediately exposes their affair and, in a victor's posture, verbally humiliates Gu Ran with insults like "incompetent live-in son-in-law," declaring that he has been abandoned by the Liu family.
