Fang Ning picked up the oval brownish-black pill and hesitated for a second before asked again, "There wouldn't be any problems, right? You better not use me as a lab rat. Natural Rebirth Pill sounds so familiar, what does it do actually?"
"Just relax. I'm well-informed so I would never lie to you," said the System confidently. "The rebirth in the name of the pill basically means that it will clear your soul of all pollutants and cleanse your spiritual sense. Once you consume the pill, it'll be as if your soul has been nurtured once more as it will lose all baggage. That way, your cultivation progress will definitely improve significantly."
Fang Ning nodded his head at first, before he realized something which prompted him to ask, "Then by your understanding, what exactly are pollutants of the soul?"
