Kill the Demon: Become the Innkeeper at the Beginning

Lu Fan traveled to the demon world and became an innkeeper. He obtained a bronze mirror that could travel to a small world. As a result, Lu Fan obtained demonic energy by killing demons, and used the demonic energy to feed the demon spirits in the small world to obtain the spiritual energy they produced. Lu Fan poured spiritual energy into the technique, and thousands of magical powers were perfected in an instant. From the ordinary [Shadow Breath Six Knife Slash] to the [Shura Demon Slaying Knife Technique] that can kill gods and demons... From the ordinary [Flying Cloud Step] to the [Xiaoyao Jade Shadow Technique] with a single thought... After repeating this cycle, Lu Fan found that he seemed to be getting a little stronger. Not only that, Lu Fan also developed new skills for the demon spirits, some producing raw materials, some growing grass and flowers, some casting weapons, and some refining elixirs... Seeing Lu Fan surrounded by many rare holy demons, scrambling to hand over the spiritual energy they produced, the immortals were puzzled and envious. "Let's put it this way, before I met my master, I had been a half-step holy demon for thousands of years." A holy demon said sincerely.
