During the Wuhu Rebellion in China, the soul of Lin Feng, a graduate student in the Department of Modern History, was transformed into Ran Feng, the general of the beggar army. He woke up in a pile of corpses and faced the troubled purgatory of "bones exposed in the wild". He gave up dependence on the system and relied on modern first aid knowledge to save himself. After entering the beggar camp, he witnessed the food shortage and the cycle of violence, and decided to use knowledge to break the situation.
Faced with the barren land and the doubts of the refugees, he promoted composting to improve the soil and planted millet seedlings using the farming method of "one foot five between rows and eight inches between plants", breaking the old farmer Chen's inherent understanding that "stinky mud cannot grow food"; when bandits coveted the experimental field, he led the refugees to cooperate with the soldiers to use compost to block the enemy and protect the wheat fields, showing his leadership for the first time.
During this period, he found a balance between Ran Zhan's iron-blooded ideals and his own modern conscience, and gradually changed from a passive survivalist to a practitioner of "stabilizing the foundation with agriculture and putting the people first", laying the groundwork for subsequent efforts to unite the forces of Hu and Han, rebuilding civilized order, and demonstrating the original intention of "protecting the people and continuing the cultural heritage" in troubled times.
