A young pharmacologist and researcher in Japan died from overworking, and was reincarnated in a Medieval Parallel Europe.
He was reincarnated as a 10 year old apprentice to a famous Royal Court Apothecary, and he had attained an inhuman ability to see through disease, creating substances, and removing substance.
In a society in which dubious medical practices are rampant, price gouging thru the monopoly of the apothecaries guild, and good medicine aren’t available to the commoners.
He was recognized by the Emperess at that time and opened a Pharmacy at the corner of the town.
He will wipe out the fraud that has swept the world, and deliver to the commoners a truly effective medicine that was developed using present day pharmacology.
Thus the boy pharmacist will cheat by using his previous knowledge to create innovative medicines while helping the people of the parallel world, a story about living his new life to the fullest this time.
