I Can Travel Through the Primitive World

[A story about traveling between two worlds and farming, focusing on the primitive world] Tired of repeating the same work every day, Jiang Heng returned to his hometown, but unexpectedly gained the ability to travel through the primitive world. There are not only various beasts such as Tyrannosaurus rex, Titanoboa, and prehistoric giant crocodiles; there are also strange giant insects such as ancient dragonflies and giant scorpions, as well as man-eating plants, and terrifying beasts with extraordinary power... Here, primitive humans are nothing more than their blood food, being at the bottom of the food chain. They can only rely on witches and totem warriors to survive in this terrifying and troubled world. Not only do they have to face all kinds of powerful poisonous insects and beasts, but they also suffer from natural disasters such as drought, floods, freezes, meteorites, and sky fires. All of this will change with the arrival of Jiang Heng, who has the ability to travel back and forth between the two worlds. While he is using the rich resources of the primitive world to help himself get rich in the modern world, he is also using modern technology to lead primitive humans to farm and develop step by step, and ascend to the throne of the food chain hegemon.
