In 2073, the “Green Tide” arrived. Acid rain corroded cities, mold covered buildings, and monsters ranging from D-rank moths to the SSS-rank Devouring Lord drove humanity to the brink of extinction.
Scavenger Ling Ye unexpectedly awakened [Source Core Resonance]. Touching a patch of mold revealed that moths feared bright light; handling a beetle shell taught him that the creature feared alkaline substances. By using what he knew that others didn't, he repeatedly escaped death. As his abilities grew, he could copy demonic soulfire, fuse with lightning and dark energy, and even assimilate the core of an SSS-rank calamity, rewriting the rules of life and death.
From a worm hiding among ruins to escape monsters, he became a force capable of enduring the abyss and inferno. Every resonance he achieved was a gamble with his life, while the secrets of the ruins behind the calamities awaited his discovery. This is the story of a Source Core Resonator's rise in the apocalypse, and a blood-soaked epic of humanity's struggle to reclaim its right to survive.
