After a thorough study, Lin Fei sensed that the Runic Art barrier was of an extremely high grade; with his current strength, breaking it was impossible.
At the same time, he was certain that with this Runic Art barrier in place, no cultivator on Earth could have ever explored what lay beneath it. Even if Wanxiu Hall or other powerful entities had entered this place, they would surely have been blocked by this very barrier. Lin Fei found no signs of the barrier having been tampered with or forcibly breached, and the spiritual power within the runes had not been activated for a very, very long time. At the very least, no cultivation power had managed to break through this barrier in the last few tens of thousands of years.
This meant there was a high probability that an Evil Spirit or a creature from the Rune Clan’s Saint Race lay beneath it.
