At the moment when Pangu exhausted his strength opening heaven, he suffered a sneak attack by eight hundred systems which sucked his blood and squeezed out his power. By a stroke of luck, his primordial spirit escaped into the Heaven-Opening Axe to survive, and he awakened a special ability to restrain systems. After his resurrection, he awakened three thousand demon gods to fight side by side, launching revenge against a crowd of evil-doing systems. Along the way, he hunted down systems, rebuilt the primordial heaven and earth, confronted the invading time-travelers and system alliance, and faced the threat of the system ancestor head-on. Hongjun, Sanqing, the Twelve Ancestral Witches, the Dao-Preaching System and other characters took turns appearing, experiencing the Conferred Gods kalpa and the ultimate decisive battle, and finally pacifying the chaos and integrating the high-dimensional world.
