For Hugo, after traveling to the world in Harry Potter's previous life novel, what he will face is a new identity, new knowledge, and a magical world that is likely to break out of war. To make matters worse, his identity made him doomed to not escape all this. Fortunately, he knows the plot and what to do in the future. Even better, he found that he had actually obtained an ancient ship-girl game in the previous cell phone as a gold finger. Not only could he strengthen himself, but he could also summon those ship-girls to the world he was in. Since then, Hugo has embarked on a road to change the plot and summon the ship's mother. And in the process, a magical world of magic that was not clearly stated in the previous life novel began to unfold in front of him.
