Primitive Survival: Starting from Infinite Taming

There are no high-rise buildings here, only barbaric wildness. Survival and struggle are the main themes of this era. Even humans who will reach the top of the world in the future will only be part of the wilderness ecology. And I, Roy, a former programmer who came here from the 20th century, was told that I have unlimited ability to tame beasts and am destined to become the king of beasts. Sabre-toothed tigers and dire wolves? No, no, no, this is the orange cat and husky of the future. Mammoths and furry rhinos? No, no, no, I told the tribe members it was a big moving piece of meat. Bison herds and logs? After processing, the logs can be turned into plows, and the oxen can be used to cultivate the land. Tame beasts, hunt, defeat hostile tribes... My territory is getting bigger and bigger, and there are more and more animal companions around me. The flames of civilization are burning brightly, burning away ignorance and ignorance. Wait, I'm really not Ding Zhen!
