Unrivaled Medicine God https://www.novelupdates.com/series/unrivaled-medicine-god/ I just started to binge read this. So far I think it's pretty good. The translations is very good and the story's narration and flow is also very good. The MC is actually creating and using medicinal pills as per the title, so it passes that bar. However, most of his alchemy activities happens off screen which is disappointing. I'm only at the mid-40s chapter as of this post, but it seems he doesn't use cauldrons (no mentions at all even for other practitioners). We've seen him modify a pill by exuding power from his finger tips and later on for a more complex job, he uses a small formation array, although there was no detail on how it was created.
