Humans and Animals Are Harmless, Mr. Xu, Do You Think I Am a Great Demon?

Traveling through the world of White Snake, he became Dr. Xu by the West Lake. His wife is Bai Suzhen? Xu Xian felt like he was going crazy. What kind of enjoyment is it to have a thousand-year-old snake monster at home? Just when he was hesitating whether to run away, the system was activated. Absorbs demonic energy and can be upgraded infinitely. Snake demon, you deserve it. In the system mall, you can get all the healing elixirs, realm-breaking pills, spells, and martial arts. There is no one in the world that I, Doctor Xu, cannot save, and the King of Hell cannot even try to snatch someone from my hands. As for demons, haha... I have two of them at home, and they are all demons raised by me in the pasture thousands of miles outside Xizi City. I thought it would be okay to collect wool to upgrade, but I didn't expect to be misunderstood as a big demon. "Yeah! There seems to be nothing wrong with it." "Yes, I, Xu Xian, am the Demon Emperor." "Want to kill me? Do you dare to do it?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
