The White Tiger Killing Power is mana born specifically for battlefield slaughter, as is similarly manifested in Xu Gou.
Strictly speaking, Xu Gou's silver-white mana is only similar to the White Tiger Killing Power. It's likely that Ying Lingyun incorporated his understanding of the White Tiger Killing Power when modifying Xu Gou, making it suitable for reference and evaluation of the White Tiger Killing Power.
Xu Gou, as an artificial Great Impermanence, not only lacks awareness in enhancing power density but also lacks basic understanding of mysterious knowledge. Yet, he displays fighting prowess on par with veteran Great Impermanence on the battlefield by wielding the silver-white mana specializing in killing.
