Traveling Through Ancient Times to Provide Porridge to the Victims, KFC and Other Foods Developed Step by Step

I want to read a book similar to "If I Can Eat White Porridge and Mustard Vegetables, I Can Do It".

Tribe, Farming, Development, Welcome to Buy! ! !

Travel back to the primitive tribe, develop the tribe from farming, and achieve unification step by step. (The system flow can be bypassed, cheating is still acceptable as long as it is not too exaggerated)

Purely Tribal, Not Systematic. Strong Recommendation

A novel without a system may be dull due to lack of exaggeration, but it will definitely be enjoyable to read.
