The Insect Queen here controlled a group of iron threadworms. It's likely that these iron threadworms had devoured a "Telecommunications Clerk." This meant the Empress's command had caused the images from other stone platforms and statues to be transferred here. So, although the stone platform and statues were visible to the naked eye, they weren't actually present here.
Chen Gu believed in his "Radiation Field" and only after much contemplation did he arrive at this possibility.
Although the statues weren't truly here, even the images alone were highly contaminating—just like the holographic projection Deputy Director Xue had shown the students. The contamination from mere images was much less than from the actual objects, but it was enough to deal with these mercenaries.
