Ye Feng did not go back on his word; in the following days, he buried himself in the research of the epidemic toxin every day, apart from keeping Nie Qingwu company with conversation to alleviate her boredom.
But the means of the Poison Doctor were too strange; although he had tried several prescriptions for experimental treatment, none had any effect.
However, one piece of good news was that White Rhizome of Imperata could indeed prevent the condition of the epidemic toxin, confirmed by its effect on Nie Qingwu.
Although several days had passed since her entry into the epidemic area and contact with those infected by the epidemic toxin, there were no signs of fever or coughing on her.
Even after she later made several unprotected trips back and forth in the epidemic area, she still had no adverse reactions whatsoever.
Moreover, when Ye Feng used his telekinesis to scan her body, he saw no black qi in her lungs formed by the epidemic toxin.
