Ushi shook his head helplessly and said.
"Eldest Brother Yoon-Jae, this is an innate ability that those of my Clan use to choose their lifelong cultivation partners, so we've never needed a reason to research how to remove it."
Ushi saw the doubt in Yoon-Jae's eyes, so he added.
"Eldest Brother Yoon-Jae, I'm telling the truth."
After a moment, Yoon-Jae lowered his sword. But just when Ushi was going to sigh internally in relief, he saw Yoon-Jae suddenly turned the sword and place it against his neck.
Ushi was shocked.
"Eldest Brother Yoon-Jae, wha-what are you doing?"
With the sword against his neck, Yoon-Jae calmly said.
"Get rid of this or else I'll kill myself."
Ushi was dumbfounded by this and perhaps thought that Yoon-Jae was bluffing, but when he looked into Yoon-Jae's eyes he didn't see any hint that he was.
Ushi started to panic a little.
