Nianshi tried to hold on tight but one hand fell on his side. He reached up again but the hole's edges were slippery like it had a substance that took away the surface's friction.

The spirit laughed at the thought the dragon had a hard time. "I don't know why it's slippery. All I know is, it's an entrance... for a reason, not an exit." He sarcastically remarked. 

"So, where's the exit then?" Nianshi's shoulders trembled from exhaustion. He was getting tired as his hand continued slipping.
