Xiuxian, My Spiritual Field Can Be Upgraded

In the world of immortal cultivation where spiritual energy is becoming increasingly shallow, it is already difficult to absorb enough spiritual energy for people to practice. And for some unknown reason, even if the spirit stone mines are dug out, the spirit stones produced will tear the meridians because of a violent force inside. High-level cultivators can withstand and dissolve it, but it is no longer suitable for low-level practitioners. But people came up with other ways, such as relying on planting various spiritual rice to maintain daily practice, or relying on some spiritual plants and some spiritual objects to refine elixirs to achieve the purpose of practice. The portable farming cave is blessed by a formation. You only need to invest spirit coins or even spirit stones to transform the spirit fields inside and grow spiritual grains and herbs suitable for people's practice. Farming caves are also divided into grades, and the higher the grade, the better the help for the harvest. Therefore, the status of "Xian Nongfu" is very high, but not everyone can pass the assessment of "Xian Nongfu". Only those who have a high affinity with the five elements are qualified to become "Xian Nongfu"...
