Modern man Chen Yin accidentally traveled to the late Ming Dynasty and became a soldier on the verge of death in battle in a border town. In times of desperation, the "Civilization Survival System" is bound - complete the mission and receive generous rewards.
"Ding! The mission is released: kill three invading Houjin scouts. Reward: a fine iron ring sword and three health pills."
"Ding! Mission released: Reinforce the city wall three feet, reward: new cement formula, fifty dan of grain."
"Ding! Mission released: Treat hundreds of wounded soldiers. Reward: Penicillin refining technique, loyalty of soldiers under your command +10."
From a soldier who charged into battle to a general who guarded one side, Chen Yanyin stepped up the ladder paved by systematic tasks and rose up step by step in troubled times. He used the gunpowder skills rewarded by the system to improve ordnance, used high-yield grains to dispel famine, and relied on advanced medical skills to save the army and the people. Facing the mess of internal and external troubles, his eyes were as sharp as a knife: "Mission? It's just the prelude to rebuilding the country. I have saved this crumbling Ming Dynasty!"
