Review Detail of Beer_Dao in Shadow Hack

Finally it's ranking gets down, I don't know what the fuss was abt this novel so I started reading it and you know what, just two days ago MC was no one but now he is so OP that all others are lunatics and dumb and stupid. And shouldn't the author must explain abt the world background a little bit first. I read till 30 chapters and it was so CONFUSING like what is this dimension, dimension coin, beast, space and all. Does the dimension is diffrent world or not and also he gets a old computer or and AI attached thingy and his other avatar is it in game world he gets the avatar. I don't know.
