Age of Swordsmen: I Recast Mankind with the Holy Sword

In 22xx AD, the earth realized the "global village" utopia, and mankind thought that peace would last forever. Until a group of "people" in ancient costumes wearing swords tore it all apart - bullets bounced away, missiles broke through the air, and nuclear bombs could not damage them at all. In ten years, the earth was divided into nine sword sects, and human beings were reduced to a second-class caste, allowing "swordsmen" to live and kill them. Li Ziming was originally the most ordinary boy in Chang'an New District, until the day of the opening ceremony, he publicly beat the traitor who reported his father and defected to the swordsman. That night, the swordsman broke into the house, his parents died, and his sister collapsed. Holding the focus gun left by his father, he knew for the first time what powerlessness meant. On the way to escape, his friend's father betrayed him, and his sister was almost killed. He was completely enveloped in despair, but fortunately he was saved by a young woman, Cheng Xiao. This descendant of the swordsman Hua Xu from thousands of years ago, the descendant of the demon-subduing swordsmanship, and the former executive officer of the Renaissance Group - an avenger whose younger brother died at the hands of a swordsman chose to protect them. In order to escape the world, she asked him to fetch water and do chores every day, but he accidentally found the artifact that Hua Xu had made to slay demons in the cave: the Holy Sword of Guanghua. It turns out that those "swordsmen" are not human at all. They are demons who were sealed thousands of years ago, and their rule is their revenge. And the glorious holy sword made by Hua Xu was a weapon specially designed to kill monsters. "Teach me the magic sword technique." Li Ziming knelt down with his sword in hand. "You will die." Cheng Xiao said. "Then die." He raised his head, "But I want them to die first." From the lowest operative of the Renaissance Group to the leader of the demon clan with a sword pointed at the earth - he has been waiting for countless years for this sword. At this moment, as a mortal, he wanted to ask the demon clan for the return of the human world.
