Chapter 307: Chapter 0307: The Number of Samples is Too Small

Nan Xun was taken aback; she always felt that Cheng Yuan was pulling her leg, but she had no evidence.

With a skeptical look, Nan Xun stared at Cheng Yuan, "Are you serious? You're not fooling me?"

"Why would I fool you? I've just sampled for poison, numbed your lips; if there were any toxins, I'd have tasted them."

"And what were the results of your tasting? Was there poison? Did it numb the lips?"

Cheng Yuan feigned a thoughtful expression and smacked his lips playfully.

Not fishy in the least, utterly sweet, absolutely a top-notch experience.

"I don't feel any numbness for now, but the sample size is too small to be certain of the accuracy, I need to obtain more samples to make a determination."

Unsuspecting of any deceit, Nan Xun asked subconsciously, "How can we get more samples?"

Cheng Yuan said seriously, "I'll just use my tongue to check! That way, I should get enough samples in one go."

Nan Xun was startled, how does one use a tongue to check?
