As Thirteen, Viola, Sharon, and Louise dashed toward the Brain Beetle, the four of them staggered after being hit by a psychic attack meant to put them under its control.
However, Thirteen was someone who had very strong mental power. Even without the Brain Beetle's attack didn't really affect him too much.
Viola, Sharon, and Louise were all under hypnosis, so they recovered immediately after the Brain Beetle's preemptive strike.
Seeing that its attack didn't work on them, it switched to a different tactic, which was telekinesis.
The giant stalactites that were hanging over the cavern broke free and flew toward the four humans with vengeance.
Viola, who had the Rank of Grandmaster, raised her hands and conjured a spear, which she used to smash the stalactite thrown at her and Thirteen.
Sharon, on the other hand, waved her hand and erected a barrier made of light, which tanked the impact of the giant projectile, smashing it completely.
