Tap, tap, tap.
The sound of wooden clogs on the floor was crisp and clear, tapping at Sato Ken's heart and making him extremely nervous as cold sweat continuously broke out on his forehead.
Quickly, under the guidance of the square-faced samurai, the two passed through the central room and along a corridor to reach the Martial Arts Arena behind the Machiya!
At that moment, in the center of the Martial Arts Arena, stood a muscular man, bare-chested with tightly knitted arm muscles. He had a Black Dragon Tattoo inked on his chest and was practicing fist technique with a two-meter-tall iron man.
The man kept thrusting his fists while shouting "hei ha" as he struck the iron man.
Clang!
Clang!
Each punch made a dull, thudding sound, which was quite impressive.
This iron man was specially made, entirely forged from refined iron with fully mobile joints, weighing at least a ton! Yet it was swaying left and right from the man's powerful punches.
Sato Ken was secretly astounded!
