Amon grinned. As he expected, the third sealed portal was still there, untouched.
All these years, Dim Loog had visited this vault multiple times, trying to breach the third portal, but he never succeeded. At first, he posted guards in this vault room to stop bandits from trying to breach the portal. However, after more than ten years, he stopped doing it. If even he couldn't break through the seal protecting the portal, no one should be able to.
Unfortunately, this theory was only valid for people of the surface world. Amon now stood before the portal. He placed his hand before the portal. He felt a strong backlash from the seal. If he were weaker, he would have been thrown back.
From the backlash, he could estimate the seal was powerful enough to resist a King Stage or Supreme Stage cultivator, but not stronger. He was a Mammoth Stage cultivator, which was one stage stronger.
