Peter Brown only realized when he arrived at the Scripture Tower that it wasn't exclusively for storing scriptures, but was actually a treasure hall.
"Why is it called the Scripture Tower?" Peter looked at Harry White, puzzled.
With a hearty laugh, Harry White said, "Initially, this place stored the Sect's scriptures. Later, as the Sect grew, the seniors simply expanded it. See that? Those three characters, Scripture Tower, were written by the Founding Ancestor. It is said they contain his Cultivation Technique. However, no one has been able to perceive it, so the characters have never been changed."
So that was it!
Peter stood there and started to look at it carefully.
Upon close inspection, Peter found the three characters to be full of aura, especially as they contained a hint of the Dao's essence.
In the Phantom Realm, Peter had come to understand Dao affinity all too well. Although the essence was weak, he managed to grasp it completely.
