The Gods that were originally watching the battle in the void were all shocked. They were still high above, but they no longer had the confidence they had before. After all, the Desolate God had been enslaved by someone from the Blue Planet! This thought assaulted their souls. No matter which God it was, they were all simply shocked.
In the entire universe, amongst the many terrifying methods, the one on top was definitely mental enslavement! At the level of the Gods, normal methods wouldn't be able to do anything to them. After all, physical pain was just so-so. The pain that could stimulate the immortals' senses would at least hurt their souls.
Other than that, anyone with self-respect would definitely be afraid of their willpower being eroded. In any case, in the eyes of the remaining Gods, the Desolate God's current situation was worse than dying on the spot! Since his ego had been lost, he might as well be dead rather than alive.
