Su Ying gestured to Zhou Qing that there was no need to be anxious. Her mouth might not be good at discerning other things, but it could distinguish between various types of medicines in a short time.
She only used her lips to lightly touch a small amount of the water with talisman paper. After the water completely wetted her tongue, Su Ying could taste the medicine. The talisman was indeed drawn up using some medicinal fluid. It seemed to be a painkiller concocted from a very common prescription.
However, the fluid was very concentrated. It was probably derived by repeatedly boiling the ingredients of the painkiller prescription and then drawing the talisman symbols with the concentrated medicinal liquid. This would explain why Nie Jun would slowly calm down after drinking the talisman paper-infused water when he was in extreme pain.
It wasn't because talisman paper cured the illness but because the painkillers were taking effect.
