After Peter activated the illusion, Anna instantly entered the illusion. Meanwhile, Peter could see Anna's experience in the illusion through the image in front of him.
At the same time, Peter first sent a message to the S-Grade queen insect to come near the Genetics College. This was his plan for the worst-case scenario.
If the insect in Anna's body was still controlling her after she escaped the illusion, Peter would let the S-Grade queen insect control Anna next and make Anna its soul slave. This was the only way to save Anna now.
After Peter told the S-Grade queen insect about his plan, he began to pay attention to Anna's experiences in the illusion.
The following was Anna's experience in the illusion.
Anna's consciousness took the appearance of a little girl after entering the illusion. This must have been an experience from her childhood.
