This mythological novel is divided into four parts, and the title seems to only have four words, right?

At first, the male protagonist and the female protagonist argued about the problem of Tyrannosaurus Rex's short-sightedness. The female protagonist was a professional dinosaur researcher, but the male protagonist said that it was not short-sightedness. Then, for some reason, they and some of their team members (who seemed to be mutants) transmigrated to the Shang Dynasty. At that time, people used dinosaurs to fight, and during that time, they seemed to have met Lei Zhenzi. Then, they transmigrated to the mythological period. Their team leader and the others who transmigrated before became ancient mythological characters. It seemed that the male and female protagonists were separated. In the end, the battle between Gonggong and Zhurong caused the Five Declines of Heaven and Man. Then, the ending was that the male and female protagonists seemed to have continued to reincarnate.
