One Piece: Body Tempering Technique, Awakened Observation Haki

Reborn in the age of Rocks, Hainuo, an orphan from Feiqing Island, awakens innate Observation Haki, granting him full access to malice detection and attack prediction! When a fellow disciple of the Wuji Sword School is assassinated by the Fengmang Sword School, he kills the enemy with three swift strikes, showing no hesitation at his first taste of murder. The Sword God's Body Tempering Art appears in his mind. Haki tempering speeds his recovery, and his talent for swordsmanship soars!

After two years of hellish training, he moves from enduring leather whips to iron rods, then to spiked clubs, and withstands a hundred-man assault with his bare body. When a pirate crew worth 39 million comes calling, he cuts through iron with a single strike, takes the head of a Zoan boar man, and awakens Conqueror's Haki on the spot!

He masters the Six Powers on his own, using Soru and Moonwalk with ease. He enters the swordsman realm, cleaving the sea and splitting the waves, then cuts an 80-meter Sea King in two with one strike! While Rocks rules the New World and Marine Admirals roam the seas, Hainuo has already sworn to reach the pinnacle of swordsmanship and become the World's Greatest Swordsman! From Feiqing Island to the New World, witness how this young man of the Blood Clan forges an invincible body with the Sword God's Body Tempering Art and tramples every foe with innate Observation Haki! Temper the body into godhood, and cut down the Celestial Dragons! The name Hainuo will one day resound across the seas!
