[Note: This book is a pure invincible novel. The protagonist is invincible from the beginning to the end. There is no system because there is no need at all] [No System] + [Invincible Text] + [Rebirth] + [Semi-Omniscient and Almighty] Ten thousand years ago in the Gaowu era, Chen Yunxuan, the strongest emperor and demon emperor, launched a war. After his defeat, he was jointly sealed by the Five Emperors. In modern times, he was mistakenly released by the Ye family brothers and sisters. In modern cities, there is a lack of spiritual energy. High-level cultivators have gradually retreated from public view. The Five Emperors have also disappeared. Powerful beasts are also on the verge of extinction. They are squeezed out to survive in the wilderness. A small number of cultivators hunt them in exchange for rewards or to improve their strength... As the ancestor of all demons and the strongest emperor, Chen Yunxuan has mastered all Taoist and magical powers. Even the techniques created in this world can be fully learned and deduced by just a glance. He came to this modern city with this skill. "The ten thousand-year-old ancestor of the Kunlun Sect? Just say that I, Chen Yunxuan, are here. If there are no consequences within a minute, let him think for himself." (Although the background of this article is in a modern city, it is a completely fictional world and has no connection with reality. It is an imaginary world view)
