Counterspace Era

An unknown cosmic event causes the earth's local or global gravitational direction to reverse, that is, the "pull" suddenly becomes greater than the gravity of the earth. In 2047, this "gravitational catastrophe" destroyed the world order in an instant: Unfixed buildings, vehicles and even people were thrown into the sky, and eventually stagnated or crashed at a new "gravitational equilibrium altitude"; the ocean rose into the sky, forming suspended "air water masses" and huge circular waterfalls; the earth's crust became fragile due to the loss of downward pressure, triggering a global geological disaster. Young structural engineer Lin Qi, geologist Shen Qingyun, and teenager Chen Xing survived the ruins and led more than 60 survivors to establish the "Qiming Point" (later developed into the "Qiming Village") at the bottom of the pier of the overhanging Xinzhou City overpass. Later, via radio, they learned that there was a large settlement called "Kunlun Ruins" "above". The expedition team embarked on a vertical journey to Kunlun Ruins, passing through floating mazes, geothermal fountains, and gravitational anomalies, and finally arrived at this fortress city suspended in the sky, only to discover that the great secret of the deep earth project was hidden there.
