Lin Yi felt somewhat helpless; before having crossed over to this world, back on Earth, he had greatly disliked teachers who would extend their lectures, and now in the Cultivation World, he couldn't seem to avoid it either.
However, this also served to show the Dao Master's earnest responsibility. Otherwise, he would have finished early and disappeared without a trace, who else would voluntarily inconvenience themselves like this with their own time?
It was just like within Liu Yun Sect's paid lecture on formations; as soon as the appointed time arrived, it was impossible to get those Foundation Building cultivators to stay for an extra minute.
He had no intention of going up there; he had already mastered integration of formations. There was no need to show off here, better to leave the opportunity to other Daoist friends.
Once someone else went up, he planned to sneak away quietly.
