The reason the twins' group decided to tell Levid about that was very simple. 'This is most likely related to the system's quest. Perhaps whatever formation Levid needs Rean to look into is what will let them escape the Upside Down World. If that's the case, we can take this opportunity to investigate or maybe even sabotage that formation,' Roan concluded.
Levid's eyes lit up when he heard Rean's words, saying, "A Golden Peak-level Formation Master! Even you're just a pawn of the Sacred Undersea Kingdom, your connection to them has definitely helped you a lot in your development with formations. Perhaps you're exactly what we need!"
Rean didn't mind it, replying, "Whether I'm what you need or not will depend on what you need me for. What kind of formation do you want me to help with? Would it be risky? What about the payment? We have a lot to discuss before we jump to conclusions."
