Song Wen's cave abode.
Sitting cross-legged, Song Wen took out the Jade Slip Chen Yi had given him and examined it carefully.
The Jade Slip's contents were divided into two sections. The first introduced seven-colored grass, while the second concerned the Yan Family.
Seven-colored grass less than ten years old looked no different from ordinary weeds. The entire spiritual herb was green, and its spiritual energy was very faint.
But once it reached ten years of age, a ring of orange would appear on its leaves.
Every ten years thereafter, another color would appear on the leaves, until its seventieth year, when all seven colors-red, orange, yellow, green, cyan, blue, and violet-would be present.
When it reached a hundred years of age, a ring of black markings would appear along the edges of its leaves.
These markings were an important indication of whether seven-colored grass had reached a hundred years of age.
Seven-colored grass bearing all seven colors could be used to refine Profound Qi Pills, pills that increased spiritual energy for cultivators in late Qi refinement. They were somewhat similar to the Qi-Gathering Pills Song Wen currently took, except that they contained far richer spiritual energy.
Hundred-year-old seven-colored grass, meanwhile, was one of the spiritual herbs used to refine Foundation Establishment Pills.
