This is the nobility of the Hundred Arts of Cultivation, a sixth-rank grand sect!
Therefore, Li Cangwu proposed to take only the Female Sword Thunderflame, weaker and slightly inferior, as his reward for artifact refining, leaving the Male Sword Heavenly Strike for Xu Yang.
But unexpectedly, Xu Yang declined, insisting on giving both swords of the Heavenly Thunder Double Swords to him.
Such an attitude, even for an Integration Great Power like Li Cangwu, was somewhat alarming.
There was no way around it, he simply couldn't afford it!
If he were to take both swords of the Heavenly Thunder Double Swords, what would he use to offer as compensation? He certainly couldn't put up the South Sea Sect as collateral.
If he didn't provide compensation, not only would he feel uncomfortable, but he might even suspect that the Heavenly Thunder Double Swords had some issue or concealed trap that could pose trouble at a critical moment.
