The protagonist "Shen Wu" was an award-winning virtual reality game architect in his previous life, and was selected by a "Big Dream System" to travel through time. The energy of the system is out of control, and it travels back to the beginning of the world. Pangu discovered that this system could actually build a "spiritual world" that was fake and real, and found it quite interesting, so he refined its core into the "Sea of Knowledge Pearl" and sent it to Pangu Palace along with Shen Wu's soul, a ray of insight into the "Idealistic Law" and a drop of his heart's blood. After Shen Wu woke up, facing the impact of Kaitian's evil energy on his mind, he had an idea and used the Divine Pearl of Consciousness and the Law of Spiritualism to create a huge spiritual world called "Prehistoric Deduction Realm". He pulled the consciousness of the twelve brothers and sisters into it. In this dreamland, the flow of time is different from that in the outside world. They can "wake up" in advance without any scruples, study, fight, and deduce. The Dragon-Han Tribulation was going on in the outside world. In the dream, the Twelve Ancestral Witches, under the guidance of Shen Wu, had simulated the "Litch War" thousands of times and found hundreds of ways to break the situation. They even deduced major events such as Taozu's sermons, distribution of treasures, and consecration of saints in advance, and they knew each person's character, magic weapon, and weaknesses well. When the Twelve Ancestral Witches truly took form and were born, what the gods saw was a group of polite, resourceful "monsters" who seemed to be able to predict the future. While Emperor Jun Taiyi was still complacent about establishing the Demon Clan Heavenly Palace, Shen Wu had already led his brothers and sisters, following the perfect plan that had been deduced countless times in his dreams, and quietly laid out a shocking move that could overturn the entire prehistoric world.
