Regarding the spiritual
roots, this is a design mistake on my part. It’s too complicated, so I’ll talk about it here.
The spiritual root levels from low to high are one-star low-grade, two-star low-grade, three-star low-grade, four-star low-grade, and five-star low-grade.
After upgrading, there are one-star mid-grade, two-star mid-grade, three-star mid-grade, four-star mid-grade, and five-star mid-grade.
Then there will be one-star top-grade, two-star top-grade...
When the spiritual roots exceed the top-grade, I will set it up separately to make it simpler.
