The bodhi root, which is the energy shield that surrounds the flower-rain tower, is the same as the one that the poison king used to protect him from being poisoned. The root is very similar to that of the bodhi, but lacks the vitality of the real one. The poison king wanted to protect the root from being corrupted, but the root is a fake, so it can't harm him. He can give the root to the poison queen.
