High-end medicinal ingredients often require the most simple ways of consumption.
Initially, Xu Yuan was worried that Tianyan would play a trick on him by swallowing without chewing, using prime energy to wrap around the Enchantress Divine Flower, but Old Man Luo directly told him that the Enchantress Divine Flower melts upon entering the mouth.
He also took the opportunity to enlighten him that the Joyful Powder could incapacitate a Saint invisibly and tastelessly because of the medicinal strength of the Enchantress Divine Flower, its main ingredient.
However, used alone, the Enchantress Divine Flower has no aphrodisiac effect; it merely causes long periods of hallucination. To create the Joyful Powder, additional ingredients, like the Spiritual Liquid, need to be mixed in.
After eating the Enchantress Divine Flower, Tianyan immediately sent a message to Xu Yuan:
"Xu... Changtian, I've... I've already eaten it."
