The scent on the sports field confirmed for Zhou Ziang that someone had just used the aerosolized anesthetic drug derived from modified Mandala.
Mandala is a type of medicinal plant with a long history. The whole plant is extremely poisonous, and its leaves, flowers, and seeds can all be used in medicine. It was one of the main ingredients in the Powder for Anesthesia invented by the divine doctor Hua Tuo during the Three Kingdoms period.
This type of anesthetic drug, containing methyl alcohol, is sprayed into the air and instantly stuns people, evaporating quickly within a short time.
By human sense of smell, within a few seconds of the drug's effect, it can cause dizziness, anesthetize the nerves, and eventually cause unconsciousness.
Zhou Ziang examined Zhang Yiyi after she fainted; her pupils were normal and her breathing stable. The amount of floral poison she had inhaled seemed minimal, so she should wake up on her own after a night of sleep.
