The oceans cover 71% of Earth's surface, yet humanity knows less about the deep sea than the far side of the moon.
During a joint expedition to the Mariana Trench, researchers accidentally disturbed a taboo that had lain dormant for billions of years. In the deepest reaches of the abyss, submersible pilot Qin Tao witnessed an indescribably magnificent ruin and a colossal “Eye of the Abyss.” That gaze became a nightmare that haunted every survivor.
Five years later, echoes from the abyss shook the globe. Sea levels rose in bizarre ways, marine life underwent frenzied mutations, and an unknown virus spread among the population. Bearing a “curse,” Qin Tao was forced to return to the deep sea in search of the key to saving humanity. But what awaited him was not only the truth, but the ultimate question of what humanity's existence meant.
As the ancient “Watcher” civilization awoke beneath the sea and a new humanity called “Sotalia” came riding the waves, the old rulers were forced to retreat inland.
Evolution or extinction? Coexistence or war? Under the gaze of the abyss, the struggle between two civilizations will decide Earth's final fate.
