Review Detail of tokhar in Reincarnated as the Demon King's Son

This novel is a gem which got destroyed after the first 50 chapters even his godly ability from chapter 2 or 3 is nowhere to be found in the story and the annoying part is a 20 something years old mc is still crying like a fool, always displaying his power for praise. why would an overpowered mc leave his godly technique to learn trash technique. Even rock blush when you look at it? and then a useless emperor still sent you to be killed. got the power to create anything just by words and guess what, you forgot about it and making the penguin steal for you? mc is a fool.
