Lin Yu, a top student in the Department of Modern History, accidentally traveled to the precarious late Ming Dynasty. Inside, Li Zicheng's uprising was setting fire to the prairie fire, and outside, there were the Hou Jin cavalry watching eagerly. In the court, there were constant party disputes and corruption, and the people were struggling in dire straits. Lin Yu, who was chased by the rebel army as soon as he landed, activated the "Destiny Changing System" and started a legendary counterattack.
Lin Yu relied on systematic knowledge to teach the people to improve farming, and skillfully used modern tactics during military training. He shined on the battlefield and became famous. Emperor Chongzhen made an unusual promotion, but it aroused the jealousy of his old officials and framed him one after another. A sudden system failure left Lin Yu isolated and helpless, with his life hanging by a thread. Just when everyone thought he was about to fail, the system was unexpectedly repaired due to special celestial phenomena, and hidden functions were unlocked.
Lin Yu used this to resolve the crisis, turn the tide, and repel Li Zicheng and Hou Jin. After that, he reformed the Ming Dynasty, developed agriculture, industry and commerce, and cultivated new talents. When expanding overseas, it encountered Western powers joining forces to block it, and a naval battle was imminent. At a critical moment, the system was upgraded again, helping him defeat the enemy, eventually conquer the world, establish a super empire spanning Asia, Africa, Europe, and the United States, and rewrite the course of world history.
