Yun Changkong was the leader of the Yun family and the tenth elder of Sky Palace. He was no stranger to Under the Sky.
Yun Suyi showed him her Under the Sky, and he immediately recognized that it was different from the original version. But the difference fixed the inherent problem it had once possessed. There were no more flaws. It had become a skill that was perfectly usable in battle.
"Suyi, did you really learn this from Han Sen?" Yun Changkong hastily asked Yun Suyi after she finished her performance.
"Yes. He's been teaching me since I leveled up to become an Earl." Yun Suyi nodded.
"Father, does the modified Under the Sky really work?" Yun Sushang asked.
"Yes, it looks like it really can. There's one thing I don't understand, however; how can your knifeskill express the feelings of the Textless Book?" Yun Changkong asked.
Yun Suyi quickly explained how Han Sen used his knifemind in a way that allowed her to get a feel for it.
