Spirit qi was essential for all cultivators. The higher the intensity, the better the efficiency when one absorbed it. And this led to a better cultivation period.
Hence, spirit gathering rune was one of the most basic types of spirit rune. One could say that as long as one was a cultivator, they would have used it before.
In a radius of ten meters, it could cause the intensity of spirit qi to rise to four times or higher compared to the outside area.
Honestly speaking, upon seeing Sun Mo starting to draw a spirit rune, everyone felt somewhat disappointed. This thing was too average and it conformed with the norms of society. There was no novelty at all.
For a scene like this, everyone had already seen it way too many times in the classes of new teachers.
Lu Changhe was also taken aback. The purpose of him coming to this class was because he wanted to see Sun Mo drawing a spirit gathering rune.
