Yu Sheng didn't know whether it was an illusion or not, but he felt that Little Red Riding Hood had been a bit nervous since a while ago.
He thought that maybe, just maybe, it kind of, sort of had something to do with him...
But luckily, he had thick skin and a broad mind (the latter mainly developed in partnership with Erin), so he quickly stood up and focused his attention on the upcoming action.
He could now feel that those security guards were static in various areas of the museum, and some were being slowly "dissolved" in the air. It seemed that as the "invader" disappeared from all the security guards' sight, the museum's "clearance" mechanism also stopped, and those temporarily generated plastic dummies acting as cleaners began to be gradually reclaimed.
However, this recycling process was slow. If they waited until all the plastic dummies disappeared before acting, they might miss the museum's opening hours.
