Feng Jun knew that Yu Zhiyuan didn't believe him, but he was indeed telling the truth, so he could only raise his eyebrows, "How about this, let them bring two kinds of poison, and see if I can deduce them."
Upon hearing this, Yu Zhiyuan's eyes lit up, "That could work, are you sure you can deduce them?"
Feng Jun nodded, "I'm sure I can deduce them, but I'm not sure... if they can afford the price of my deducing service?"
"It's not interesting to talk like that," Yu Zhiyuan sighed in frustration, "Does a test also come with a price?"
Feng Jun gave him a look, clearly implying—Isn't that obvious? "Forget it, I'll give you a piece of news for free, the anesthesia on the arrowhead is actually synthetic neurotoxin, Gao Qiang is at risk of brain damage... Luckily, I've administered some antidote."
Hearing this, Yu Zhiyuan's eyes brightened again, "Synthetic neurotoxin... Can you explain in more detail?"
