When the humanoid monsters entered the lab room all of them were affected by the five formations that Amara activated earlier.
Normally she would have been able to control the formations so that they would not affect the humanoid monsters, but now that she had already lost her mind and was not controlling the formations manually, even humanoid monsters were being affected by the formations.
Most of the humanoid monsters ranged from B rank to A rank so their spiritual power was not strong enough to fend off the effect of illusion formation like Evan.
They just took a few steps inside the lab room before they were trapped inside the illusion and stopped dead in their tracks.
Amara was already being controlled by her monster instincts so when she saw those humanoid monsters, she opened her mouth and spat out a jet of golden flames on them.
