Knowing the fixed rule of the Chrono Hollow changes the assault team's approach.
In order to spread and map the entire place starting from the safe area, Rex would stay near the center of the safe area—while the others went to the edges. All of them monitored their force energy and came back to Rex when it was almost depleted.
Going together would make the scouting inefficient.
On top of that, with them spreading, Rex doesn't need to maintain a big red force barrier.
He could keep it minimal, keeping it to himself and only expand it when others needed his aid and rest. Liliya also already marked all of them with her enchanting mark, and the scouting of the Chrono Hollow began.
Naturally, as opposed to staying put, Rex was keeping an eye on the sky.
Despite the rule of the dominion, the mutated birds were still another threat to deal with.
Looking at the two boulders, Rex steadied his breathing in preparation for his theory.
