I Can Become Stronger by Slaying Demons

"Kill the first-level demon clan of Ning Yuan and gain one month of cultivation!" "Kill the first-level demon clan of Ning Yuan and gain one month of cultivation!" "Behead the second level demon clan of Ning Yuan and gain two months of cultivation!" My name is Lu Wu, and I am a swordsman in Dazhou. What is a knife-wielding hand? Hold the sword of the human race and behead the foreign race. One day, I discovered that I could become stronger by slaying demons. Since then, nothing has been the same.
