Chapter 428: Clearly Insane

Chapman looked at Nan Yan and calmly said, "You've already retrieved your people; it's time to give me the antidote."

Chapman was known to be flexible and adaptable. Now that his life was in Nan Yan's hands, even if he harbored thoughts of dismembering her in his heart, he couldn't show it on the surface.

Nan Yan didn't waste any words on him either.

With both Bai Chen and Shen Junqing in urgent need of treatment, she had no time to waste here.

"Open the door, let us go, and I'll give you the antidote immediately."

This door had become the lifeline for Chapman and his group. Without this door, Nan Yan estimated that she would have massacred the entire Seven Deadly Sins headquarters today, leaving no one alive!

"Miss, since this is a trade, I've already handed them over to you. You need to give me the antidote first before I can let you leave."
