Mu Ying had already transformed and planted quite a number of plants from the Emerald World.
Based on her experience, there were roughly three patterns to Nature's giving of Experience Value rewards for new types of plants.
The first was that under equal conditions, magic plants provided more Experience Value than ordinary plants.
The second was that plants she personally cultivated and created, such as Binding Vine, provided more Experience Value than re-cultivating existing native species from the Emerald World.
The third was that the more stable a plant was and the higher its Value, the more Experience Value it would provide. This Value referred to the plant's value to other organisms or the environment, the simplest being edibility.
Most ordinary plants generally had decent stability, but their Value was rather average, so they didn't provide much in terms of Experience Value rewards.
