Comments of chapter undefined of Book 1 of the empire : reincarnated in BAFIAW with a system

Once more it is simply impossible to understand what is going on... Seriously, the author should stop asuming that everyone has read every story that exists... I don't know who is this person or beast he speaks of. In fact, I don't even know most of the names of the people that are already with the mc. Actually, the only characters I am able to follow so far are Green, Merlin and Meg. Maybe the twin brothers too, though here I am not so sure of their names. Stone and wood maybe?
