Blessed by the System at the Beginning, Determined to Become a Blind Swordsman

[No heroine + Kendo + Demon] In June of the twelfth year of Xingwu, fire fell from the sky! Twelve blood moons crossed the sky, and the shadow of the devil loomed within it. From then on! The world is undergoing great changes. Under the influence of the twelve blood moons, people's temperaments are competing to alienate them! The evil spirit that transformed into one of the twelve blood moons! Since then, the world has been restless! The demons and ghosts hidden among the crowd wantonly devour the surviving humans. But at this moment, Emperor Wu was nowhere to be found! The world went crazy saying that everything was done by Emperor Wu, from then on! The world is in chaos, alienated evil spirits are raging across the world! Martial arts practitioners carry the banner of the world, slay demons and eliminate demons, and disputes continue! Because demons can transform into human forms! Moreover, people's hearts have changed. Even if the martial arts cultivators are strong, under the continuous attack of the evil spirits, the martial arts has taken a sharp turn. They are so suppressed by the evil spirits that they cannot lift their heads. They can only survive. In the great world, they allow the evil spirits to wreak havoc and cling to their own one-third of an acre of land! I hope that another Emperor Wu will appear in the world and quell the disasters
