Torture
Ryu's words didn't contain even the slightest hint of embellishment. The moment he sat down to enter a state of meditation, he knew that regardless of what happened, even if he made the worst mistakes of his life in quick succession, his mother would be able to guarantee his life.
His mother was the Saintess of the Life Shrine, and not only that, but she was now on the verge of the Omniscient Sky God Realm. With the Shrine at her back, she was easily as powerful as a weaker Dao Lord.
Of course, these were just Ryu's estimations, and he wasn't completely certain. It wasn't until recently that he could just barely make out the demarcations between Sky Gods, so trying to guess at this stuff was difficult.
Even so, even if Himari was just a True Sky God, or even just a False Sky God, just how easy would it be for her to protect Ryu now?
