Tang Youyou looked at Xiao Qiang and said with some surprise, "Are you saying that poison is not poison, but medicine?"
Xiao Qiang nodded and said, "The purpose of poison is to save people, not kill them. Yet, the poison you made, despite seemingly perfect in its ingredients ratio, is in fact vastly different in potency due to the varying ages of the herbs. It might work against a level-8 martial artist, but it would have a hard time against a level-9 martial artist and a true inborn powerhouse. Simply because their bodies are much stronger and wouldn't fear such poison, rendering it meaningless in the end."
"So you mean..." Tang Youyou looked at Xiao Qiang with confusion. Although what Xiao Qiang had just said seemed plausible, it didn't mean she would necessarily believe him. Especially when it comes to using poison, Tang Youyou is very confident in herself.
Xiao Qiang chuckled. He slowly took a vial from his clothes and said slowly, 'To kill a man, one vial is plenty.'
