Sanctuary-realm

What kind of power is this!? It's the Sanctuary-realm, it definitely is the Sanctuary-realm!

When Lin Li killed the Undead Elemental Dragon previously, Archbishop Martin was already speculating in his heart that Lin Li had probably already entered the Sanctuary-realm. Now, he was even more certain that that was the case. There were hundreds of Legendary-level Corpse Dragons opposite them, many of which were at the peak of the Legendary-level. Only those with the power of the Sanctuary-realm would be able to resist such attacks effortlessly.
