Ring of Commitment.

"Mmh." Isaac squinted his eyes. The room was immensely dark. He couldn't see anything or feel anything. After he took a step forward, a light appeared.

In the middle of the room, there was a stone table and chair. They were carved by a knife. The edges were very sharp and crude.

At the top of the table was a candle. The candle had a small fire flickering. The area around the table was enveloped in a yellowish hue.

Ding! Ding!

A holographic screen emerged from the darkness following the dinging noises and hovered above the table. While the screen sent a bluish light everywhere, the table was shrouded in a warm, honey-like, yellowish shade.

Isaac grabbed the stone chair's backrest and dragged it away from the table.

Screech!

While dragging, the familiar scratching marks appeared on the stone ground. Isaac used his sleeve and wiped the sweat away. He was starting to get very annoyed.

He had to do a lot of physical activities and was getting mentally very exhausted.
