Qiu Tu shot Wu Zhi in the face, an act far removed from sending Wu Zhi to his death without God or ghost noticing.
Therefore, after deciding on how to deal with Wu Zhi, Qiu Tu had been contemplating how to kill him without arousing the suspicions of Huang Shangzong, Yan Chen, Commissioner Wang, and others.
It was at this time that Qiu Tu returned to his villa and met Shen Lingshuang.
Shen Lingshuang told Qiu Tu that she had concocted two potions for him over the past few days, one odd and specific, which she gave to Xiao Bai to fixate his cataclysmic ability, and the other was a "Cataclysmic Awakening Potion." (Chapter 231)
That bottle of "Cataclysmic Awakening Potion" reminded Qiu Tu: he still had a mighty weapon in his hand!
It was the precious Cataclysmic Material he had salvaged from the "Salvage Game," "the overflowing spiritual entity of a Cataclysmic." (Chapter 152)
