Chapter 231: Chapter 230: Soul Gate!

"A soul gate… I was lucky enough to witness one myself, and I believe that it is a passageway that connects the spirit world also called the afterlife with the Human Realm, allowing a being from the Spirit world to cross over to the awakened continent but not the other way around–as the entry of living being inside the spirit world is said to be strictly forbidden. After all, it's determined that the presence of a living being can cause undesirable effects in the afterlife. Any more questions?" Zachary explained what is a soul gate to Whitaker, and patiently waited for him to reply.

Soul Gate is the dimensional gateway that can be opened by a Twilight Walker to summon their contracted spirit. It is one of the official and safe ways that a contracted spirit can use to leave Spirit World and help his master to fight against the forces of evil. The soul gate takes the form of a suitable sized gate. Thus, it is called a soul gate.
