This Pirate World Is a Little Different

When Luffy traveled back in time and became a child, he thought that he would get a teaching system that was not very reliable. It not only changed Luffy's physique, but also taught Luffy to awaken his domineering energy and exercise physical skills. He also developed fruit abilities and told him the conditions for fruit awakening. After Luffy started his adventure at the age of seventeen, he taught his friends domineering skills and their respective training directions through the system, and helped his companions obtain devil fruit abilities.
