Am I Actually the Strongest? 6 (Light Novel)

The original light novel series of the popular isekai manga! To be reincarnated into another world with the promise of a 'cheat' power is one thing... but to be reborn as a baby, and then left for dead after your royal parents think you're powerless? That's another thing entirely! Now the newly-born Reinhart - or Hart to his new friends - must find his way through a dangerous world... but luckily he's got magic that's quite literally off the charts!
