My Most Powerful Demon-Killing System

[Non-traditional cultivation of immortality, emphasis on reasoning, don't join if you don't like it] In an unexpected incident, Xu Lingyun was bound to the most powerful demon-killing system. As long as he killed the demons, he could obtain various weapon skills. Later, he joined the mysterious organization, the Demon Suppression Division, and accidentally exposed the secret of the jade pendant. Since then, all kinds of evil spirits have appeared one after another, such as Rakshasa birds, bee demons, five-eyed birds, guhuo birds, mermaids, flower spirits... Bodhisattvas block thunder from the sky, eight-arm smiling corpses, deep vats with long fingers, burials with five coffins and thousands of stacks, yellow wolves knocking on doors at night... All kinds of strange cases occur frequently. From then on, Xu Lingyun embarked on a treacherous, thrilling and bizarre journey.
