The protagonist traveled through the prehistoric times and became a ray of Hongmeng purple energy that was about to be refined by Hongjun. Awakening the "Ten Thousand Dao Guizong System", every time you make a choice, you can absorb a fragment of the origin or law of heaven and earth. Before Hongjun's union, the protagonist chose to hide, using the body of Hongmeng purple energy to open up thousands of immortal dynasties in his body, secretly absorbing the neglected creatures and incomplete avenues in the world. When the circulation of heaven is not smooth in the future and the Six Saints find that certain laws or children of destiny that should have appeared disappear, they are shocked to realize that a dynasty of ten thousand immortals that transcends the heavens has been born in the depths of the wilderness.
