I Took My Computer and Traveled Through Ancient Times to Build Infrastructure.

[Big heroine + natural disaster + infrastructure + golden finger + no CP] Han Xinxin traveled through time and became a dark little village girl. She originally thought that with the wisdom of modern people, she could show off her talents in ancient times, but natural disasters came one after another. Extreme heat, extreme cold, earthquakes, insect plagues, plagues... Human nature is slowly disappearing, people exchange children for food, and there are many people who kill and eat meat. How should Han Xinxin, a salty female college student, survive with her parents in this cannibalistic world? Don't be afraid, we have a golden finger and want to survive? Ha! That's not easy! Find a valley, set up a caravan, recruit a group of followers, and live a peaceful life from then on. When others are lying outside in the scorching sun like a dead man on the roadside, praying for alms from nobles. Han Xinxin and her parents lay in the air-conditioned room, eating ice cream worth dozens of yuan. When war comes, others live in fear. Han Xinxin fell asleep beautifully looking at the valley built with copper and iron walls. No way! Who let Han Xinxin win the favor of the Fox Fairy? Life is so beautiful!
