These were all things that could be used for aiding cultivation. Whether it was talisman medicine or magical weapons, they were a long-term business in the Lower City.
Zhou Family young members would carefully seek and purchase these basic materials, such as spiritual grass, talisman paper, or refining materials.
During this time, they haven't had any problems. As a result, the Zhou Family's shop would occasionally sell low-level magical instruments. In doing so, they indeed made a profit and acquired many spirit stones.
This formed a positive cycle. In the Lower City, where the majority were Qi Cultivating Stage cultivators, the cultivation goods at the Zhou Family's shop were naturally in high demand.
However, the Zhou Family's young members were still cautious. When they purchased materials, they would rarely make repeat appearances in one place. Thus, they hadn't encountered any problems thus far.
