The forest was big—too big to even seem realistic. Standing beside one of the trees, they look like they were transformed to become smaller instead of the trees being bigger.

As they approached the forest, the wolves' noses twitched before they started releasing a low growl. As soon as they came close to the edge, shadows flew from the nearby shrubs straight toward Ein's face.

The wolf Ein was riding released a powerful voice loaded with mana, creating a powerful shockwave. The shadows were pushed back and lost their balance before plummeting straight to the ground. With a swift wave of his claws, the wolf created three avian corpses, bleeding profusely, lying on the grassy earth.
