Hiroki should've just dodge Ren's attack, then run and hide behind the king. That way, Ren's attack have a chance to hit the king when it misses Hiroki.
so, somebody just happen to have the same ring as somebody else that he knew from past life, and he immediately think that guy is a reincarnate?
flawless logic right there
@WhimsiCat exactly what I was thinking. Besides, this guy want to meet someone equal in term of intellect, but he sent fighters to a boy who got his attention and test his physical strength(?). I don't know, that sounds stupid to me.
