[Not a wish-fulfillment novel, no harem, no clichés, no invincible protagonist, no System, just the author's high school fantasies] The Gate to the Other Shore opens. In a world brimming with spiritual energy, humans have fought demons for hundreds of years. Once the Demon King obtains all the sacred relics, he will be able to break through his seals and shackles. Meanwhile, as time passes, humanity's cultivation gains are no match for the demons' growing strength. If they are not wiped out soon, the consequences will be dire.
