509 Who really has no medical ethics

"What have you found?"

Nie Qingwu was dizzy from Ye Feng's shaking, and it took her a while to break free from his grasp. She asked in confusion.

"I found out why Little Boy wasn't infected by the plague and how to prevent the disease from spreading!"

Ye Feng's eyes shone with excitement, unable to contain his enthusiasm.

"What is it?"

Upon hearing this, Nie Qingwu's heart also rose to her throat, and she asked half-believingly.

Going out to mold a clay man and then coming back with a method to prevent and treat the plague—this was naturally met with skepticism.

"This!"

Ye Feng raised the White Rhizome of Imperata in his hand, excitedly saying, "With this, people who haven't been infected by the plague don't have to worry about catching it anymore!"

"Just this? Grass roots that pigs eat?"

Nie Qingwu was doubtful; she remembered that Little Boy once said that his mother had told him that only pigs would eat this kind of grass root.
