Dodu swallowed the quadruped faceless one when it was hit by Charon. The elven sentinels, Vitae and Adrian's two companions all stared wide eye. The enemy they were having difficulty defeating is actually taken care off by the squishy thing in front of them.
The elven sentinels have no recollection of the thing that swallowed the faceless one because they were not born yet when the extermination of slimes happened. The elven sentinels could guess the origin of the liquid monster in front of them, but they are not a hundred percent sure.
They thought that everything is safe, and they could now escape but Dodu suddenly started to jiggle violently. Levin Cloud asked Dodu if everything is fine, but the slime only showed a disgruntled expression. A few seconds later, Dodu vomited out the faceless one that now looks like a flaming ball of fire.
