The team's division of labor was very clear.
Dr. Eisenberg was responsible for sorting out theories about "wormholes" and "multi-dimensional space", while Jiuyue and the Judge were responsible for maintaining the prison's daily affairs before the research was implemented.
As for Duan Mingyuan...
This Mage was not idle either; he and Number: 37 walked into the small meeting room and started addressing the problems of the Specters.
The Specter Squad was the trump card the Shan Clan People had planted in the prison. According to their plan, once Duan Mingyuan and his group left, the Specters would act again, and even if Eisenberg was unwilling to leave the prison, they would find a way to forcibly remove him from there.
