"How stupid must you be to put the Heaven Three Leaf Grass and Dark Shadow Flower together! The Heaven Three Leaf Grass contains the purest light energy, while the Dark Shadow Flower is formed from the purest darkness energy. To put these two together is sure to cause death!"

In contrast, light and darkness were always conflicting forms of energy, with no chance of any integration or peaceful interaction.
