Cretaceous: Evolution of Tyrannosaurus Rex to BattleGreymon

During an archaeological excavation of dinosaur fossils, Chu Xu accidentally traveled to the end of the Cretaceous period and became a Tyrannosaurus Rex cub.
Transformed into the king of dinosaurs and bound to the daily evolution system, Chu Xu began to evolve madly from a Tyrannosaurus Rex.
[In the early stage, hunt small prey such as rat-toothed beasts, chewing lizards, and slender-horned dragons, spend 100 evolution points, and evolve into Agumon. ]
[During the teenage period, you have hunted medium-sized prey such as Strange Dragon, Ankylosaur, Pachycephalosaur, etc., and obtained 1000 evolution points, and evolved into Tyrannosaurus. ]
[During the youth period, hunt large prey such as Triceratops, Quetzalcoatlus, and Mosasaur, obtain 1 evolution points, and evolve into Mechanical Tyrannosaurus. ]
Adulthood...
From then on, a generation of Tyrannosaurus kings swept across the prehistoric Cretaceous period, evolving step by step towards the ultimate form of Battle Greymon.
Until one day, a fragment of an asteroid from outer space fell from the sky, causing the dinosaurs to face an unprecedented mass extinction, and a bizarre new world began.
At this moment, a dragon-like giant beast wearing golden armor appeared out of nowhere.
