After Augustus relied on the information regarding the soul crystal, Fairy Xue Yan instantly went to report it to the Master of Iron Mountain Sect.
Augustus followed as Fairy Xue Yan told him to do.
"There's no way to prove that it's true unless someone who survived Yan Mo's Era still exists in the mortal world."
Following the logic, it's impossible unless someone ascended to immortality; they won't live past a million-year age.
The person speaking is the Master of Iron Mountain Sect. He looks particularly young for a master, but upon examining it with the system, Augustus found out the strength of the master of the sect he joined.
