Acquire Trust. 

Reon was left alone in the room. She had nothing to do so she casually looked around the room. The opened treasure box caught her attention.

Reon stared at the box for a few seconds. She heard the loud screams of goblins and the sound of limbs falling to the ground.

After a few more seconds, Reon walked up to the box. She examined the treasure box from outside before she squatted down in front of it.

The green mist had got Reon super curious. To check what it was, she pulled her hand to touch the mist. As soon as her hand went past through the mist, her health went down.

"Oh." she realized what the green mist was there for.

Reon leaned a little forward and peeked into the treasure box. She saw the same image of the key Hitori had shown her.

Unconsciously, Reon tried to touch the key that sat in the green mist. Again, her health went down but that did not stop her.
