Boss of the Demon Suppression Department: I Kill Monsters with Unlimited Upgrades!

Ye Fan traveled through time and became the lowest trainee of the Demon Suppressing Division. Fortunately, with the awakening system, as long as you kill the demons, you can deduce the techniques infinitely! Others have practiced hard for ten years, but it is not as good as him killing the demon with one blow. The Dragon Elephant Demon-Suppressing Technique has been advanced to the 10,000th level, and the body has become holy and immortal! The Blood Killing Sword Technique has been deduced to the extreme. With one sword, it can open the gate of heaven and kill all kinds of enemies! From being a trainee as a demon-suppressing guard to being a powerful force throughout the ages, Ye Fan only did one thing - kill! Kill demons, evil spirits, gods and demons, kill everyone who refuses to obey! Several years later, an ancient god descended from the sky and looked down at the world: "How dare a mere mortal dare to defy heaven?" Ye Fan took one step forward, the dragon elephant roared behind him, and the golden bell shook the world: "Heaven? What I am killing is the sky!" This novel and its characters are purely fictitious.
