An Lin's heart jolted upon seeing the characters on the scroll.
He thought about the mysterious death of the Spirit Patriarch, then looked at the countless True Demon Tribe bodies and other mysterious bodies strewn across the ancient battleground, and countless thoughts rushed into his mind.
An Lin continued to unfurl the scroll to find that it contained a plan detailing how the Ancient Fiendcelestial of the True Demon Tribe had cooperated in secret with another certain Spirit Tribe outside of this realm in order to kill the Spirit Patriarch. However, this was a very general recount, and only the duties of the two true demons An Lin had just killed were elaborated on with specific details.
The place where the plan was initiated was this battlefield.
