Giant Crocodile: I Can Travel Through Prehistory

[Alien beast flow + non-transformation + random prehistory + multiverse + god system] Xu Wu was reborn, but the place where he was reborn was not right. It's not a splendid palace, nor an ordinary delivery room, nor even a vocational high school toilet - him! Reborn on the gridiron! Reborn as a little crocodile that is about to be eaten. Just when Xu Wu was cursing God, the system appeared. Bite! Your prehistoric system has been activated. Please open the novice gift package quickly and be prepared. You will be transported to a random prehistoric world immediately. The countdown is - 10, 9, 8... When the countdown ended, Xu Wu was thrown into the Cambrian period 530 million years ago by the system, and began a three-day struggle to survive, surrounded by ancestor-level bosses. No, I have become a junior? Trilobite ancestor? Wapta shrimp senior? Xu Wu discovered that eating them could actually gain evolution points. What else is there to say? Just eat it. Devouring = infinite evolution, unlimited breakthroughs in body, glands, perception, and explosive power! Travel through the Cambrian, Mudbasin, Jura, and countless recent random prehistoric eras, sweeping across the top predators of all eras. I thought I was just traveling through various prehistoric eras to work like crazy and continue to grow into the overlord of Blue Star. But as the size and strength reached the ceiling of the era, the truth of the system gradually emerged. The afterimage of the Black King on the incomplete murals and the dusty secrets of the fallen god system were uncovered layer by layer by Xu Wu! The timeline has been disturbed, and the darkest era has brought death to all beings. The culprit turned out to be—me?
