After MC reborn, i tryed to make MC as regular guy like us but for plot improvment and future knowlage purposes i gave a system as just knowlage transfer. So technically MC has any public information from our world. So how MC can know "everything" because of system. There is also some changes in body. I wanted to make the MC as best of the best but humanly possible. After the "rebirt" i want to cut off all the magical and supernatural things. So yes MC have access to all future knowlage but other than that there will be no other magical thing in the story.
