He almost thought that he had repeated his lesson, but he soon realized that it was wrong. He was a little old, but his memory was not that messed up.
He had clearly not taught that before!
"You..." Mei Siren opened his mouth.
"It can be considered an insight." Xu Xiaoshou laughed, too lazy to explain.
He had found a way to cultivate it after Master Siren had explained it.
The knowledge of Sword Technique Expertise was truly complete. There were methods such as Soul Stripping, Imperial Decree, and Contract in it.
It was just that in the past, Xu Xiaoshou could not understand why Sword Technique Expertise included these strange things.
Now, he was suddenly enlightened with new insight.
Mei Siren suddenly felt that it was boring to take this disciple. He had not tasted the joy of being a teacher and pointing out the wrong path. He had been suffering setbacks all this time.
