I read this while it was a book and it was pretty good.
So in the book he is locked in his house but manages to get a couple of monster birds to attack his house and fall to the ground to die. This give him the experiencepoints required to level up. Upon leveling up the range of his skill increases to the neighbors rooms where he gets the next door father to hunt monsters. This futhers his ability grows the more space it takes over and the more skill he has access to. He gets the power to make those under him knights awakening their abilities and he can make anyone of his citizens living in his territory become a sudo awakener. This is good because normal people cant level up only awakened people can. As time goes on his territory grows and this allows for more people to come under him and get him more experience to grow faster. He eventually finds his Grandmother who is in a coma with the ability to make people under her also sudo awakened. His Grandfather is the gaurdian of the world tree. Later that day his Mother and Father are found, his Mother has the ability to make people who she is close with awakened and his Father has the ability King making him the King of a territory he owns. That is where I left off.
