Weapon seller in the world of magic

After a couple of hours, Mark reunited with his women.

He didn't know what happened during lunch time but he could see the ladies are a lot closer than they were before a couple of hours.

What changed is how Song Yue and Shen Ling were addressing Sylvandria with sister as a prefix. Previously, there used to be a certain wall between them, the one that separates normal people from having casual conversations with true experts.

After returning to their VIP Box, Mark once again made sure that the room was secured before settling down and having a talk. He talked about Qing Jie's proposal and Song Yue told him what happened in the ladies section too.

Mark couldn't help but burst into laughter upon realizing that both of the parties were on the same wavelength. Here, he refused Rong Huang's invitation, and there, Sylvandria taught Rong Huang's wife a lesson.
