On the primitive Earth, although chimpanzees were massive in size, the beasts they faced were even larger, making it impossible for a single chimpanzee to survive alone. As a result, large groups of chimpanzees gathered together, dividing responsibilities and cooperating for survival. Gradually, the most primitive chimpanzee tribes began to form. With the formation of these tribes, constant warfare broke out between neighboring chimpanzee tribes.
Thousands of years passed, and numerous chimpanzee tribes were merged, forming regional chimpanzee tribe clusters. Over time, chimpanzees rapidly transitioned from primitive society to a society based on slavery, then to feudal society, and finally entered the era of modern industrial civilization. In the course of the Ape Tribe's evolution and development history, a total of 500,000 years were spent. Throughout this evolution, war and slaughter were persistent themes.
