Anthony continued to softly knock against the wall, as if feeling for something. After a while, he noticed a straight line and a slit beside it.
"This looks like a door cut out in the walls." He whispered and stabbed his dagger into the slit. Surprisingly, it entered smoothly to an extent before it stopped. Anthony began to turn the dagger in the slit, but it was hard to twist over. He tried a few more times, but turning it around while standing at a spot was quite difficult. The only option seems to move along with the dagger. He took a step back and quickly flipped in the air, taking advantage of the velocity to force the dagger to turn. The moment his foot touched the ground after the dagger made a full 360° revolution in the slit, he heard a crack and the mighty stone door clicked open, sliding into the other wall.
