Many people, although filled with anxiety, had no choice but to test the poison with gritted teeth.
That's just the way of the world. If you want something, you have to give up something in return! Even if it means betting your life!
People generally believe that producing a colorless and odorless poison is the pinnacle of mastery in poison-making. However, there's still a higher level, that is, deception!
The poison created by Xi'er is an example of deception. She had mixed several odorous toxins together to create a new toxin. Remarkably, the scent it emits is identical to one potent toxin!
An experienced poison master would intuitively conclude that the poison she has concocted was refined from that very toxin.
If they truly attempt to neutralize the poison in this manner, they would not only fail to neutralize it but also exacerbate the poisoning, making it incurable! Either they succeed, or they die trying!
