Is there a lot of grinding?

There is so much grinding, like you have to fight a lot of monster while exploring the map, when I first played it I thought it would be like SAO but I was wrong, I still enjoy the game it just takes to much time to complete task and unlocking map, the character as-well take to much time on grinding up and MAXING them out, so make sure you have an empty calendar before you start playing. You might get hooked on Genshin.
