[Absolute Rule: "Create a separate space!"]
Idri used his world authority and created a massive separation barrier in the space-time fabric, thus separating the area within a radius of ten kilometers near the temple.
This way, the rest of the dragon valley will remain unaffected by the fight between the two giants.
Moreover, he sent a message using telepathy to the other SS-rankers to create their own barriers; this is the reason why none of the students felt anything strange in the mana during the evaluation test.
The SS-rankers had already isolated everything, and due to that, the students never saw the fight between the two demi-gods.
Even Link, who was so close in the vicinity, didn't sense it, as a separate barrier was placed on the temple.
