He threw the chopped flesh to his own hound, while the large chunks of the body were thrown into the cage. Alright, now we know what's inside the cage.
Seeing this, Leon recalled the event they encountered when they first entered.
They had just stepped into the Path of Living Sacrifice when they heard hurried footsteps ahead, and a few animated corpses came running toward them from the front.
They initially thought it was a sudden attack, but to send just a few fragile animated corpses was underestimating them too much. Leon was about to cut them down when he noticed that the animated corpses had no intention of attacking, they just kept trying to flee but were tackled by the following hounds, with heavier footsteps coming from not far away.
Leon and his team hid in the nearby bushes to observe the situation and witnessed this scene.
He could now confirm that the Cage Man was not chopping up bodies out of anger because the actions were clearly part of a task.
