Got the Wrong Script! I Became the Father of the RPG Protagonist

As a young man, I came to a world of dragons, magic and miracles, and I also had a son. Before he had time to adapt to his new life, my ordinary son unexpectedly received a major mission and was about to embark on a journey of adventure and redemption in this world... Can he do it? I really can't imagine that I am living in the world of the RPG Brave Role Playing Game that I have played countless times. Fortunately, by coincidence, I am not the protagonist, but the protagonist's father. Survival, learning, fighting, love, where will our father and son go in the future, and what kind of ending will we have? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
