Jack approached the weird tall hills accompanied by Alfredo's asura while the others stay back and watched. He changed into his supreme dragon form and activated gold scale armor as Peniel told him to.
He saw dense clusters of red dots around those tall hills. Peniel informed him that these kamikaze monsters were insect-type monsters. This type usually attacked en masse.
Once Jack came into a certain range, one of the nearest tall hills burst like it was made of sand. Perhaps it was. Out of that crumbling hill, hordes of red insects surged out.
Jack used his Inspect. These red insects were Volatile Firefly Ants. They were mostly level 60 elite monsters, weaker than the sabretooth walruses. But their number made it clear that they could swallow those walruses in seconds. There were also a few amongst the horde that was special elite grades and had higher levels up to level 63.
Duke Alfredo's Asura took point while Jack fired ranged attacks and spells.
