As they venture deeper into the cave, Qin Zuijia could hear the sound of the surging waters. The cave temperature became higher as they walked towards the light. The room shines blue and red interchanging every after five seconds. Qin Zuijia could hear the sounds of crying souls from the other side gradually quiet down, and the sound of water splashing to where they were heading became clearer. It gave him a sense of assurance that he won't have to see what kind of room would hide and enslave thousands of souls, forcing them to yell out profanities and cry for help.
The sound of Magma splashing the giant room carries a heavier impact than if it was actual water colliding with the walls. The room was rather large and empty which made the splashing sounds echo all around, even attracting those from outside to take a look at why there was different heaviness with the collision.
