He just needs to place the successfully concocted pill in front of him, applying the Power of Purification, controlling its strength not to be too strong, to avoid purifying too much of the Pill Poison within, making the grade of the pill too good.
With Li Zhirui's current realm, he can completely purify tens of thousands of pills in one go, and the time consumed might be less than half a quarter of an hour.
But he won't divulge his abilities to anyone at all, after all, there are still quite a few existences in the Tao Spirit Realm more powerful than him, and if the word gets out, the trouble it brings would be immense.
He might even have to live a life of anonymity and homelessness once again.
But now, Li Zhirui already has bonds and attachments, and it's no longer a time when he could be indifferent about everything on his own.
So he must be extremely cautious, not to leak any bit of information.
