The Greatest Philosopher With Zero Magic Power.

As he lay dying, the Great Philosopher expressed deep regret that he had never been able to master the art of magic. Half a millennium later, he was reincarnated as Mazel Loran, the son of a feudal lord. His family believed that he was simply a late bloomer when it came to discovering his magical abilities, but they also believed that he may be the Great Philosopher reborn. However, Mazel kept a secret from everyone - he lacked magical abilities, but instead had knowledge and experience in the field of physics!
