[Strong women, time travel, farming,]
When Ye Aman, a doctor of botany, opened his eyes, he was actually dressed as an abandoned woman from the Helan tribe of the Great Yan Dynasty. She was thrown into the -20°C Death Valley by her ex-husband Batu because she was "infertile". She was surrounded only by the wandering wolf Huiya who knew how to find water and guard against wild beasts. When she was on the verge of death, she touched the 5 kilograms of virus-free potato seeds she brought with her when she traveled through time. She relied on modern knowledge to collect manure compost, plow the ground with a wooden plow, and grow the first wave of potatoes in a desperate situation.
On the way, she rescued Murong Jin, the Nanchu proton who was unconscious from the cold, and the two formed an alliance over "potato planting" - he helped find tools and plan fields, and she helped collect tribal intelligence. With the harvest of potatoes, the two attracted abandoned old and weak refugees and established a new tribe of "distribution according to work". They refused to treat men as inferior to women, but they attracted Batu's people to visit and steal food. Ye Aman asked Huiya to sneak attack on the cavalry, and the refugees rolled potatoes to beat back the enemies, and the tribe's cohesion skyrocketed.
During the crisis of salt shortage, the two led a team into the Wild Wolf Valley to find salt springs. During a snowstorm, they huddled in a cave to keep warm. Murong Jin shielded her from the ice. After their relationship warmed up, they confessed their identity as the prince. Batu teamed up with the Black Wind Division to encircle and suppress the enemy. Ye Aman used "potato mines" to fight back. Murong Jin was knifed to protect her and eventually captured the enemy leader. Faced with the elders' doubts about "using sorcery", she proved herself with a gunpowder manual, and was hailed by the refugees as the female leader of the "Potato Department".
Murong Jin had to return to the country to take the throne due to the civil strife in Southern Chu. Ye Aman escorted him with elite troops and Huiya, and set up a potato trap to repel the queen's killer. After helping him ascend the throne, the two held a "potato banquet" to link up with other countries and formed an alliance in which "Southern Chu provided agricultural tools and tribes passed on technology." Ye Aman became both the female leader and the princess of Chu, relying on potatoes to create a double legend in troubled times.
