Gao Wu: Drawing a Sword to Burn the Sky, Is This Called Scrap Iron?

The abyss descends, the demons resurrect, and Blue Star enters an era in which all people awaken to their martial souls. In this world where martial arts are used to determine class and future, Jiang Wuzhou only awakened an F-class rusty iron knife with no spiritual power. The family abandoned him, the chaebol suppressed him, and the geniuses at the same school mocked him wantonly. Everyone regarded him as a low-paid loser who was worse than cannon fodder. Until that day, the Death Killing System is activated! As long as you kill the demon, you can gain spiritual pressure, unlock the Death God template, and extract the peerless Zanpakutō and Supreme Kidō! Soon after, tens of millions of abyssal beasts surrounded the main city, and humans were retreating steadily. The ninth-level God of War to protect the country is bleeding in the sky, and endless demons are about to devour all survivors. When all mankind fell into despair, Jiang Wuzhou walked up to the city wall alone and pulled out the rusty iron knife. "Everything in the world is turned into ashes, and the blades flow like fire!" In an instant, the sky-burning flames swept across the sky, and a hundred thousand demons and ninth-level beast gods were instantly turned into ashes in the flames! The hundreds of millions of humans in front of the global live broadcast fell into complete silence. Later, Hyōrinmaru was frozen for thousands of miles, the mirror flower, water moon, and everything were turned upside down, and Senbonzakura shattered the stars! The federal marshal trembled all over: "Who said this is F-class scrap metal? This is clearly a world-destroying magic weapon!" The Demon King of the Abyss wailed in despair: "Run quickly, that god of death with a knife is here to buy goods again!"
