Calculations

The members of the Boulder tribe were injured in the ensuing battle. They retreated with the other warriors who followed Aru's suggestion. 

Meanwhile, Aru continued on his battle. 

Fortunately, at the same time, the quantity of demons coming from the demon well also decreased.

It almost seemed like the end was near.

The retreating warriors, numbering about one hundred and fifty, moved a short distance away from the demonic well. The stronger warriors took charge, directing others, while a smaller group tended to the wounded, bringing them closer.

The injured were brought to the center of the group, while the rest formed a circular formation to repel the demons.

The warriors swiftly organised themselves.

Despite their number being in the hundreds, the demons were unable to breach the formidable defence formed by the warriors.
