Ah Dai was taken aback and said, "Conditions? What conditions?"
Harsfin said, "This condition is actually very favorable for you. As long as you can defeat me one-on-one, I will join the human camp and help you deal with the Bone Dragon, Nazgul, and Harbank. How about it? Of course, after the deed is done, you must take me away from here to see the human world, and I promise not to kill indiscriminately."
Ah Dai felt a surge of joy in his heart and glanced at the other three Sword Saints, saying, "How can I trust that what you're saying is true?"
Harsfin replied earnestly, "It's simple, I can swear! I swear in the name of the terrifying demon Harsfin, that if you, young man, can defeat me, I will obey your commands. Is that enough for you?"
Yun Ying said in a deep voice, "What will happen if you break your oath?"
Harsfin said, "If I break my oath, let me never ascend in all eternity."
