"Agh!" William winced as the effectiveness of his pain resistance lessened over time. The System continued sending warning messages, but William couldn't even spare the energy or attention to read them, focusing entirely on the imparted knowledge of the Primordial Soul Devourer Technique.
It had only been four minutes, but William's Sea of Consciousness was already showing hairline cracks, and his Soul Strength had been dealt with time and time again. While he hadn't lost any Soul Strength, William's control over it lessened until he was no longer able to manipulate it.
Am I going to die like this? William thought in regret. Out of all the things that could kill him, he didn't expect his life to end this way. He thought about Fria, who had probably requested this reward. He couldn't imagine she'd be any better off than he was, considering her recent Ascension.
