Confusion

Within the cage of essence sucking metals, Hela and First Saint Son were still lying, now devoid of most of their energies. They had never felt so weak in their lives. Unfortunately for them, Dyon had forgotten to check his trap after he came back from Chaos Universe, resulting in this scene.

This was definitely a new kind of torture. Not only could they not cultivate, there was nothing to pass their time with. If it wasn't for the fact they had another human across from them, they might have started to go mad. Luckily, they were also martial warriors, so their mental strength surpassed that of mortals.
