"I... have understood!?"
A murmur of sudden realization, he then rose and went outside, only to see the sky rumbling with thunder as many cultivators returned from their tribulations, disregarding their disheveled appearances to rush back inside to listen to the lecture.
"Fellow Daoist!"
Seeing this, he immediately stopped someone: "What year and month is it?"
"How would I know?"
The person he stopped shook his head and then slipped inside, showing no desire to entangle further.
"One does not know the year inside the observation!"
Seeing this, he chuckled and strode outside, drawing long, ominous clouds with him.
...
"Thirty years have passed, spring and autumn have gone!"
Inside Wuzhuang Temple, Xu Yang chuckled lightly, stopping his lecturing and looking toward the seated cultivators: "Has everyone gained something?"
"Great Immortal's wonderful teachings, we have benefited endlessly!"
