It didn't take long for Ye Zi and the others to find the source of that strange feeling. It was discovered by the Erlang God in a hidden cave deep at the foot of a mountain. Using Ye Zi's words to describe it, they saw a soul of a person trapped by several dozen thick chains deep within the cave. Calling it a soul feels a bit off, but since it doesn't have a physical body, there's no other way to refer to it except as a soul. They suddenly appeared in this world, and it's almost certain that this is the handiwork of Ling Wei Zi Mo from the Myriad Demons Country, so it's speculated that there's definitely a meaningful reason why they were thrown here by that person.
