Death is inevitable.

The desperation was very clear in Jiaqi's voice. She quickly added to ask, "I took the poison from you, so you must have the antidote, right?" 

The man on the other side of the call hummed. "Yes, if you have taken the poison from me, I will have its antidote for sure. But miss, the antidote will come costlier than the poison, you must know this." 

This was the rule of the venom market. While the poison might come cheap, its antidote or cure was always costlier. 

Yun Jiaqi was already ready to pay any cost. In the situation she was stuck in, she didn't care about money. 

She was glad that at least the man accepted that he had the antidote. She knew he would have it. The dealers always describe their products exaggeratedly to build interest; she had guessed right that it had been the same case.
