Open the Door and Kill the Demon

Late at night in Jinhai City, the demonic mist seeping out of the abandoned hospital completely changed the life of bookstore clerk Chengge - his sister Lingning was attacked by a demon. He accidentally awakened the demon-slayer's birthmark, inherited the family's demon-slaying blade, and opened the "demarcation gate" between humans and demons. From then on, the bone armor demon in the underground parking lot, the poisonous mist in the ancient temple and the underground palace, and the black water demon in the reef cave became his daily routine. Fortunately, the cool shooter Yao Anna (the holder of the gilded chain), the talented young Lin Miao (the developer of technological spells), Mr. Chen who holds the evil-breaking dagger, and Ling Ning who can predict the crisis formed a "demon-slaying team" to work alongside him. They set out from the Jinhai Sea and crossed the cracks in the demon world in the Arctic Ice Plains. They united with the neutral demon clan to fight against the ambitious Black Abyss clan, and searched for a balance amid the question of "whether humans and demons are enemies." When the leader of the Black Abyss Tribe, Xuan Ye, activated the two-realm teleportation array and the demon emperor's bones were shrouded in black mist, Chengge finally realized: "Open the door, slay the demon" is not a slogan, but a promise of protection - to keep the early steam, campus laughter, and a peaceful night for ordinary people. From the store clerk to the leader of the Demon-Slaying Alliance, from the battle in a corner to the decisive battle between two realms, they spent ten years proving that: to slay demons, they slay greed and malice, and protect the symbiosis of human beings and all things. And this protection will eventually continue to write the legend of "open the door and slay the demon" when the new boy takes over the demon-slaying blade.
