Blood-Eyed Shura: Destroy Villages at the Beginning and Become a General in the End

[Navy flow + cool system writing + single female protagonist + decisive killing] Here is the purest naval justice, and the most passionate attempt to change one's fate against the will of heaven. See how Uchiha Hato, in the name of Shura, practices absolute justice that does not tolerate evil on this sea! Uchiha Hato, who was transported by a large truck, will never forget the bloody dusk on his sixth birthday. When the pirate's butcher knife dyed his hometown red and his parents hid him in the cellar to die alone, it was the ultimate anger that ignited the power in his blood - the Sharingan awakened and the ninja system came. "I want there to be no such evil in this world!" After being rescued by Lieutenant General Garp, he devoted himself to naval training in the craziest way. When he was still practicing basic swordsmanship at the same time, his Sharingan could predict all attacks; when others were afraid of those with natural abilities, his fire escape ninjutsu had burned away all evil. To suppress bandits in the East China Sea, he frantically destroyed thirty-seven pirate groups; he eliminated Colonel Rat, who colluded with pirates. From "Blood-Eyed Imp" to "General Shura", he made pirates in the entire East China Sea frightened. "Pirates will be pirates, and evil must be eradicated!" But when he pointed his sword at the four emperors and killed Mary Joa, he discovered that the deepest darkness in the world - the supreme Im, actually nourished himself with "the evils of the world" as food. "In that case, let's chop it into pieces together with the root of this evil!" Ps: New to the book, please forgive me. If you have any suggestions, please leave comments. Thank you!
