After the "dimensionality reduction storm" 10 years ago, the Ruins fled to the earth with high-dimensional residual energy, causing 70% of the area to become a "folded area" (disordered physical rules, such as time loops and two-dimensional objects). The human survivors are divided into three factions: Old K's "Iron Dome Base" (which relies on modified technology to survive), the "Anchor Keepers" (who protect the high-dimensional anchor point at the core of the earth), and the "Energy Chasers" (who plunder residual energy for profit).
In order to find out the cause of death of his father (who first explored the folding area but was turned into two-dimensional), Su Ye took the incomplete experimental log to find an anchor point; Ye Tang (who contained high-dimensional particles implanted by the Xu clan in his body and could sense residual energy) was hunted by the Xu clan and accidentally broke into the Iron Dome base; Old K (who had participated in the military's "Dome Project" and had a blood feud against the Xu clan) took the two of them in, but concealed the secret of "disabled weapons" hidden in the base.
When the team passed through the folded area, they encountered "two-dimensional ghosts" (pioneers of the Ruins who had not completely reduced their dimensionality) and energy chasers. The truth was gradually revealed: the anchor point was the "dimensional regulator" of the prehistoric high-dimensional civilization. The Ruins wanted to use it to return to the fourth dimension, and Su Ye's father's "two-dimensionalization" was actually a disguise to secretly protect the core of the regulator. At the same time, Ye Tang's memory fragments emerged - she was a "descendant of the Anchor Keepers" of prehistoric civilization, and she was bound to Su Ye; Old K also faced a choice: use disabled weapons to destroy the Ruins, or take the risk of activating the regulator balance dimension.
