I am going to release two books with two concepts with the same story :
1.) Original concept: Where mc got nothing in the start and slowly gets stronger with the help of himself and his friends.
2.) System concept: Where mc got reincarnated and also got a system at the start of the story and got op with the help of the system.
As I say the story is going to be the same but with the addition of the concept in the story somewhat the whole story is going to change.
I am going to release a single chapter every 2 to 3 days.
