Looking for a Love Partner in a World Full of Monsters?

Traveling to a world filled with all kinds of demons and monsters, Lin Xuan, a staunch materialist, puts on the system and while exterminating demons and protecting the Tao, he is struggling to find a normal opposite sex and fall in love. "Hey, your tongue is too long, isn't it? You don't look like a human being..." "And you! The fox's tail is exposed!" "Don't hook your claws on my clothes!" "Stay away from me, I don't like non-human beings." (For his own happiness in the rest of his life, Lin Xuan began to look for someone to fall in love with in this world.)
