Fool's Bargain

"I apologize but people here do not have the capacity to learn such skill..." Monk Du curtly explained. 

Prince Houyi immediately glared at Chun Hai as he asked through gritted teeth, "He has the capacity to learn it and I don't?" 

"I did not teach him either-"

"Then how?!" 

"I simply gave him some objects that allowed him to temporarily use the skill..." Monk Du explained and then kindly offered, "I can give you the same objects if you want." He said, then he slowly reached into his sleeves and held out his palm to reveal little round blue jewels sitting there. 

Prince Houyi frowned at his hand, trying and failing to scrutinize the objects from the distance. He then motioned to his right-hand man to go over to bring them to him but then Monk Du went on to say, "It has to be you. To be able to use them, you need to drip your blood on them for me to go on to activate them... It has to be done between me and you."
