Lin Wantang is dead. Died in the flames of the laboratory explosion. At the last moment before her death, she was still thinking about her sister who died in a car accident three years ago. When she opened her eyes again, her mouth was stuffed with bitter bark, and her mother's sobs were in her ears - she had traveled through time. In the third year of Qianyuan, a severe drought lasted for seven months. The whole village was chewing tree bark, and her family was left with only a shabby house with air leakage from all sides. What's even more absurd is that the sister she thought she would never see again was screaming in her mind: "Sister! Why did you come here! I've been waiting for you for three years!" The sister became a system elf, trapped in a space called "Civilized Fire". There is black soil that can accelerate growth, spiritual springs that can cure diseases, and a library full of modern knowledge. Separated by the barrier of life and death, the two sisters, one farming, the other checking information, forcibly carved a way to survive in this cannibalistic year. Digging wells, making tofu, making gunpowder, defending the city, opening workshops, setting up schools... While others were still chewing tree bark, she had already made the whole family drink meat porridge. When the barbarian army pressed on, she used the black powder taught by her sister to blow up the city wall into a sea of flames. But she wanted more than just to live. The space that had imprisoned her sister for four years told her that by accumulating enough merit, her sister could truly walk out of that door. So she began to change the fate of more people - promoting Quyuan plow so that the poor had food to eat; promoting vaccination to make smallpox eradicated; taking in orphans so that they could read.
