Why didn't the original god help the grass god?

Morax, the rock god of the original gods, did not help Nashida for two reasons. The first reason is that Li Zhong doesn't know Naxida. He only knows the previous generation of the grass god, the benevolent tree king. The second reason is that the gods can't interfere in each other's affairs too much. Li Zhong created an illusion that he was dead, so he couldn't be seen through helping Naxida.
