In 2077, the catastrophe of "entropy change" tore reality apart. A dimension of chaos called the "Entropy Realm" has quietly arrived. It feeds on human despair and releases reality-distorting "entropy shadow" monsters and deadly cognitive pollution. The survivors discovered in despair that the so-called safe haven-the "Final Judge" system was actually a trap leading to destruction. This is a recursive death game driven by three "entropy cores" (order, chaos, and observation). Its ultimate goal is to destroy all dimensions and achieve true "no survivors."
