Gu Shenwei chastised himself harshly.
His family has laid dead for about two years, and he has stolen into Golden Roc Fort with the purpose of slaying the whole of the Supreme King's family. However, he has not killed a single master.
Amnesia quietly unleashed its prowess, as Gu Shenwei realized that he has gradually gotten used to the life of a killer. Kowtowing to his master, pandering to his master's interests, he has naturally placed the interests of Stone Castle first and just as Tie Hanfeng had said, "once you've gotten used to it, it no longer feels like a responsibility." However, a young man needs such a burden, for it is the sole purpose behind his existence.
He could not wait any longer for Peripheral Force, and the Death Scriptures reminded him of his impending death, and they left him less and less time.
Looking at the entire Gu family's demise from the perspective of a killer, the matter was definitely fishy.
