"Finally, the Spirit Gathering Grass has matured."
Early the next morning, Zhou Changwang stood in the backyard of the Spirit Field, a slight smile of satisfaction on his face.
The mark of the Spirit Gathering Grass being ready for harvest is when their originally green leaves turn blue-purple, having absorbed enough Spiritual Qi.
The deeper the purple, the better their quality.
However, it doesn't mean that once the Spirit Gathering Grass starts turning blue-purple, it can be left to grow purple indefinitely.
Spirit Gathering Grass has a very short period of maturity, usually only three days from when the green leaves begin turning purple; after three days, the purple leaves start to turn black.
Once the purple leaves turn black, the original Spirit Gathering Grass immediately turns into Poison Spirit Grass, only useful for refining Poison Pills, poisons, and its value greatly diminishes.
