Jin, the God of Discipline

Coughing up a bit of blood, Jack tumbled down the rocky valley wall and hit the ground beside Maynard and the others.

"Didn't think ya were as stupid as me," laughed Maynard.

Jack smiled and wiped the blood from his mouth. He then pulled out two bottles of life spring water Jack had collected back in Ponlinne's tomb. "Here. This will stop the internal bleeding."

While Jack and Maynard drank the healing water, the other party members were startled by Jack's statement.

"We're fine now, so don't worry about it," Jack added, calming the party. "Now, I think I know what to do."

Still in a rush, Jack returned to the water and hurried to the bottom at full speed. When Jack reached the tunnel, he didn't stop or slow down. Instead, Jack closed his eyes and aimed where he thought the barrier might be beneath the rock.

Lucky for Jack, his assumption was right. As his body came in contact with the rock, he phased right through it.
