Mo Hua returned home in the evening and couldn't fall asleep in bed.
For one thing, he was a bit worried about Da'hu and the other two; for another, he thought that despite being a cultivator, he seemed to have no means of attack or self-defense.
The cultivators in Tongxian City were simple and honest, and having grown up there, he hadn't encountered any dangers. But the absence of danger didn't mean that danger would never come.
In the face of real danger, one should have some means of self-protection; it wasn't an option to just sit and wait for death.
Mo Hua was not a Body Cultivation practitioner; his Blood Qi was weak, so he couldn't learn the martial arts of Tao Cultivation. That left him with only the option of learning spells. However, Mo Hua's Spiritual Power wasn't strong either, and what's more, as a fourth-level Qi Refinement practitioner with low Cultivation, it was a bit early for him to learn spells...
After much thought, the only choice left was formations...
