Rui and Kane were shocked, but they forcibly suppressed their reactions as they focused everything they had on getting out. If the two of them made even a single mistake, it would truly be game over. Even Rui did not think he could survive an endless wave of Squire-level ants attacking him from all directions simultaneously.
Both of them needed to do their jobs just perfectly. Kane needed to maintain Void Step and ensure that he never stopped, even if Rui did, since he was the one maintaining the Void Step technique.
Rui, on the other hand, was responsible for navigating the way out. However, he couldn't just pick the most straightforward path since a lot of these paths were getting clogged up with ants that were rushing in. He needed to not only find paths that were free enough for them to travel through but also paths that weren't clogged up yet.
