When Su Jingxing destroyed the various strongholds of the Xia Family in the Yu Nation, apart from obtaining the Mighty Strength Cards and Martial Arts Practice Cards from a pile of barbarian corpses, he also obtained a pile of Internal Force Cards, Skill Cards, True Energy Cards, True Essence Cards, Equipment Cards, and even Deduction Cards.
Although the Xia Family had colluded with the New Chu Nation, there were also geniuses among them who created their own martial arts.
After these people died, the cards extracted from their corpses were Deduction Cards.
There weren't many, only five of them.
However, there were a total of 20 deductions, with chances of success ranging from one-sixth to one-third.
At this moment, Su Jingxing had completed his self-created martial arts theory. Without batting an eyelid, he took out these five Deduction Cards and began deducing silently.
