Xiao Qing was cultivating in the backyard, where one could see the leaves of many medicinal herbs had wilted.
This was because most of their medicinal essence had been absorbed.
After dealing with his own affairs, Qin Niu took advantage of the moonlight and sat down beside the herbs to cultivate.
Unlike Xiao Qing, he practiced the Everlasting Spring Technique, which could, in fact, help the herbs recover quickly, regrowing their medicinal essence.
At that moment, Xiao Qing had reached her limit and had to stop cultivating.
After watching Qin Niu for a while, she did not disturb him but went back to her room to sleep and rest.
The cultivation of most techniques consumes spiritual power.
Many people cultivate for one or two hours, and then recover their spiritual power through rest, meditation, and other means.
