Doomed To Be A Bookworm DDTBBW

The story of Raphael Lance, an extremely talented and gifted young boy whose entire family's had been destroyed and who was raised by his mother. One day while he was playing in the woods, his spirit fused with a part of the Heaven's Library which holds the records of every single events that happened since the birth of the creation of the universe. Well, il held as it was destroyed during a war between angels and demons. The library fused in the form of a system which allows the already greatly talented to have deeper and better trainings. The only catch is that while other people have bottlenecks due to talent, ressources, or weak foundations, Raphael's "bottlenecks" are due to lack of knowledge.
"What do you mean lack of knowledge? I'm already more knowledgeable than my grandfather who is a 558 years old Saint and famed as the 2nd man with the richest knowledge in the world" (Raphael)
"Compared to the universe and the knwoledge it holds what host knows can't even compare to a speck of dust" (system)
"I've already read all the books in all the libraries in this world" (Raphael)
"There's no greater and better book than the world itself. Host must observe the world around him, compile them into books. There's always great joy in giving than receiving" (system)
