That was indeed the case, and Casio understood it well.
However, based on the Black Mechanism's statistics and estimates, the North and South Secret Martial Arts World of the Hong Li Federation combined had no more than about a hundred fighters. Of these, 60% held public important positions, and 40% were hermits.
The whereabouts of these recluse masters were uncertain. If Casio were to look for them one by one, it would probably take forever.
Therefore, he could only rely on the help of the Black Mechanism.
