Things in this world were usually quite ironic like this. To the brutal and ruthless Kahn, his younger brother Roger was one of the few people that he really cared about. Therefore, when he learned that Roger had betrayed him, he was in grief. His emotions were so stirred up that he wasn't able to cast a simple magic trick. But to Roger, this big brother Kahn was like a towering sky-covering tree, blocking his way to develop, snatching away the sunshine and rainwater that should have belonged to him, and completely shadowing his growth, so that he could not succeed. Hence, he loathed Kahn and it didn't bother him to provoke Sui Xiong's group with the intention of getting Kahn into trouble.
Sui Xiong could not understand the relationship between these two brothers.
