Zhu San had also mentioned the Yinyang Trisage Technique before. He had even used Combat Tactics to try to learn the beginning of the Yinyang Trisage Technique, but he had only ever managed to learn the initial portions. However, that was incomparable to the true Yinyang Trisage Technique.

Even Qiong Xi'er herself had only brushed against the border of the true Yinyang Trisage Technique.

Apparently, Lu Yin had just seen the old man break through Lan Xian's inner world with the Yinyang Trisage Technique.

"Are you Qiong Xi'er's master?" Lu Yin asked.

The old man hiccupped. "Did she mention me?"

"No, but I heard her mention the Yinyang Trisage Technique that you just spoke of," Lu Yin replied.

The old man gave a disdainful snort. "That girl has absolutely no intention of cultivating at all! What's the use of toying around with the economy all day long and thinking about how to make more money? Her elder disciple’s been studying star energy all this time, but now she’s gone missing."

The old man suddenly turned to look at Lu Yin. "Did you see my older disciple in that place?"

"Your older disciple?" Lu Yin felt utterly confused.

"Liquor Hero." The old man took another drink of his wine.

Lu Yin was taken aback. "Liquor Hero’s your disciple?"

The old man wiped his mouth clean again. "Yeah, did you see her? She never came back after going to the Perennial World."

Lu Yin was completely surprised. Was this old man both Liquor Hero and Qiong Xi'er’s master? No matter how one looked at the two, there were no similarities...
