Start: Namikaze Minato Invades Impel Down!

Lei Luo traveled through time, traveled to the Grand Line, and became a navy. He originally thought that he would cause trouble on the Grand Line. Unexpectedly, after Goldfinger arrived, he realized that his home ground was not the Grand Line, but the Ninja Underworld. According to the information given by Goldfinger, the ninja world is slightly different from the anime he watched in his previous life. Because, during the Fourth Ninja War, Otsutsuki Kaguya was not sealed by Sa Ming, but chose to self-destruct, pulling the entire ninja world into the underworld. Lei Luo's golden finger can take Lei Luo into the underworld of the ninja world, find various strong men in the ninja world, and issue tasks for them. Once completed, they can be resurrected in the Great Line. At the beginning, Lei Luo found Namikaze Minato and Uchiha Itachi in the ninja underworld and issued a mission for them. As a result, Impel Down, which had never been invaded in 800 years, ushered in its first invasion. ………… This novel and its characters are purely fictitious.
