"Xukai, that is your name right?. I am sure you know the end results of continuing practicing magic using the Black Stone?". Yichen asked Xukai, with a mischievous grin.
"Heavenly gods help me!. You know too much this whelp!!!. Yuming, he must be one of those spies father told us about. Hey punk! You have been caught by us, now you are not leaving this place alive anymore". Xukai told Yichen, ready for combat.
"Xukai, Xukai!. Don't do anything rash only to complicate matters for us. You can not win him even if you use half of your powers". Yuming tried to persuade Xukai, from fighting Yichen.
"Yuming, i know you are yet to recover from the previous energy loss. Half of my powers you said?. Leave him to me, i can handle him alone!". Xukai, boosted proudly to his sister.
"Okay, crazy mysterious human! Get ready to follow me back to the Demon Realm as my captive either dead, or alive!". Xukai told Yichen, aggressively.
