Just now it finally cliqued to me who are those people. They are the ones that send Shou Hei Kun to qin. No wonder all that rabble about betrayl and shit. I knew they were talking about him, but only know I figured it out.
Shou Hei Kun showed his true colors. If the story follows historical events then he will probably betray Qin and be slew by his best friend Moubu later. Now that i think of it, it was actually foreshadowed by Ryo Fui that Shou Hei Kun isnt the type to follow someone to the end.
