The Ancestral Beasts That Traveled Through the Cretaceous

In the age of the dinosaurs, the ancient behemoths, life once again bloomed. Dinosaur civilization flourished, with a history of 150 million years of evolution and tens of thousands of species. The human Li Yuan accidentally got a "mysterious small stone bead", and because of it, he traveled to the Cretaceous period and was reborn as the "ancestral beast". Knowing that the small stone beads were powerful and heaven-defying, he gradually understood that they were not a product of the earth, but maybe a product of alien technology. The most important thing is that the "small stone beads" are leftover from the dinosaur era! Could it be that alien civilizations visited the Earth hundreds of millions of years ago? Caused the extinction of the dinosaurs? The mystery of earth's civilization is caused by "small stone beads"! ! !
