During this endless imprisonment, Annan had already tried too many methods.
But none of them worked.
He had tried adjusting the knob on the right side of the TV, to see if setting it to a corresponding position would interfere with the videotape. The result was that the device could only be used to adjust the volume and brightness.
He also tried directly attacking the TV screen, to see if breaking the glass would allow him to crawl inside, or if after smashing the TV he could leave the room... The result was that neither was possible. Furthermore, the TV that was smashed by Annan would return to its original state after a period of time.
Annan had also attempted to attack the room's door, windows, and walls.
But all sorts of energy attacks he used simply passed through, as if attacking an illusion—it was not an issue of how solid they were, but that he didn't hit them at all. Annan's attacks were completely ineffective.
Annan even tried to transform into Chariot Form.
