The protagonist has no desire to dominate the world, no extraordinary intelligence, and he doesn't even understand the language when he first returned to ancient times. How to find a foothold in ancient times without basic living abilities? How to survive?

Wei Ran couldn't get used to sleeping on a bed made of straw, and the hard straw made his whole body uncomfortable; he couldn't get used to wearing coarse clothes, especially underwear, and the skin on his inner thighs was worn out throughout the day, causing pain when he moved even slightly; Wei Ran couldn't bear to be with him. Lice coexisted, and they made him unable to calm down; Wei Ran squatted on the latrine, watching the uncle hand over a few leaves with a naive smile. He was stunned, looked at the latrine full of maggots, and finally accepted the leaves resignedly. By this time, his legs were numb from squatting.
