Traveling Across the World from Prehistoric Times

In the ancient world, the weak preyed on the strong, and the small worlds were like ants fighting for food. The powerful could destroy a whole world at will. Li Changsheng embarked on the path of spiritual practice as a mortal, and every step was startling. He witnessed strong men trampling the rules wantonly, and he also saw a cruel truth: only by plundering and devouring can he remain invincible in the endless reincarnation. He traveled through the emperor's world, the resurrection of terror, the era of spiritual energy, and the universe of sword repair... He left his mark on each world, simplifying the complex techniques, practicing when he breathed, and enlightening when he walked. He conquered the female ghost Su Hongling in red, supported his abandoned disciple Ye Wuya, and teamed up with the scientist Lu Jiuyuan to combine physical skills and swordsmanship. His shadow gradually covers the sky. When he swallowed all "others and me", closed the timeline, and became the only one in the past, future and present, he discovered that the creator of the novel in the real world was actually the "dimensional observer" who controlled everything. Thus, a cross-dimensional duel begins, at the cost of the order of the entire universe. When the protagonist kills the creator and all heavens are unified, where is the boundary between reality and fiction? Is human beings just a dream in a higher dimension?
