Ling Long Di Yi Ji Jing Bian Ban

After a catastrophe destroys the old civilization, humanity's survivors live aboard the Lighthouse, a floating fortress above a surface overtaken by the lethal Mana ecology. Mark commands the Hunters on expeditions below to recover supplies, and every descent brings them face-to-face with life-draining creatures and mysteries the society above cannot explain.

The Lighthouse maintains survival through rigid social classes and laws that suppress emotional bonds. Mark's relationship with Ranbing and his conflict with Charles make those rules increasingly difficult to accept. As discoveries on the surface accumulate, the line between “surviving” and surrendering one's humanity begins to collapse, leaving the Lighthouse's future tied to truths its leaders would rather keep buried.
