@unisol_gr44 Heading down the left tunnel, Kyouka soon sees it growing more narrow, before it opens up again. Now, she sees a circular stone chamber, with statues lining the wall, and a statue of a warlord in the center. As torchlight illuminates the statue, they see that it's clad in real armour, an exceptionally fine set of samurai armour, in fact.
Jian sees writing engraved on the breastplate, in a language unknown to him, but that has some connection to that of his homeland. He thinks he can make out the words
prove thyself.
Kyouka, looking down at the statue's sword, sees that it's a beautiful blade. Pulling it slightly out of its sheath, she realises that the sword is incredibly sharp, and made of a steel superior to her own, and perhaps even the purified steel of the nanban.
