Yukkichi's manga / #reincarnation(287)

Very interesting. It's amazing how accurate the information is to match the medical facts. From the formulas, to the medication used, and the symptoms of each disease. The author really did his research. That's how you should really use your knowledge from previous life. Lately is easy to put a nobody in the isekai world and make him use simple mechanics from games and RPG, everyday knowledge from a more advanced world or just by being self aware OP. This manga is the one you say: that's how you do an isekai genre!!!
