Review Detail of Charizard6 in Isekai Journey Of The Magic Archer

I really liked the story till the end of first volume .But it all went downhill from there More than 50 chapters to describe 2 days of him returning back to his family Then how he fall in love with a girl who is more than 120 years old in a single day and he is not even 12. So much many more things I find unnecessary . Also I find demons too powerful if just one marquis rank demon and do damage to all of the continent .
