Slaying Demons: Beginning as a Catcher to Prove the God of Martial Arts

As long as you consume your lifespan, you can practice martial arts infinitely. Lu Cheng traveled through time and became a small county policeman, with a lifespan of less than a hundred years. Fortunately, by killing the monsters, you can obtain their remaining lifespan. When He Bo marries a wife, he kills him; when the dragon makes trouble in the sea, he kills the dragon. Where there are monsters, kill them! In the troubled world of monsters, show off your long sword! What evil spirits are there, destroy them all! From the Demon Slaying Sword Technique to the Heavenly Demon Emperor Sword, from the Eight Parts of Vajra Kung Fu to the Prison Suppressing Golden Body Technique. A hundred years of evil? Thousand-year-old demon? Stay, your longevity is destined to mine. Genius understanding? What is that? Talk to me about my endless longevity. ………… A few years later, the Demon Saint came across the sea and bluntly said that the human race had no great emperor, and he wanted to turn thousands of human beings into blood food. In an unknown forbidden land, Lu Cheng opened his eyes and crossed thousands of miles of mountains and rivers with one sword, taking the lead in the demonic tide. The whole world was shocked.
