Wang Cheng: Boss Chu, I think my mom will not agree two hundred percent with our affair, so I have a once-and-for-all proposal, do you want to hear it?

Wang Cheng: It’s very simple, why don’t we break up and not worry about anything?

Chu Yifeng: What you said is quite reasonable, but we can discuss this matter further in the bedroom.

Wang Cheng: …I’m just kidding. Look at my sincere face. How could I break up with you?

Chu Yifeng: It’s too late.

Skyfire Avenue is a street that is 2048 meters long. There are 168 stores here, and each of the store owners is an extremely powerful adept. The Avenue does not permit any vehicles or any robots to pass through it, much less mecha. Even the patrolling police must move about on foot. This is because this is a street for pedestrians, a lane for nobles, hidden away within this high technology world. Lan Jue, the greatest of the mercenaries, code-named ‘Zeus’, has secluded himself here in Skyfire Avenue after the death of his wife. The name of his shop is “Zeus’ Jewelry Store”, and here in Skyfire Avenue, he has been given the title, Jewel Master.
