Traveling Through the Three Kingdoms, I Helped Guan Yu Defend Jingzhou

Li Zhao traveled to the Three Kingdoms and brought with him a system that can deduce the direction of history. He wants to go home. There is only one condition for returning home - to unlock the historical deviation to 100%. According to the design of the system, the fastest way to unlock it is to use your deduction ability to help your side win the battle and create the largest causal deviation. To put it bluntly, it's killing people. He defected to Shu Han, used the system to help Guan Yu see through Lu Meng's white clothes crossing the river, and helped Ma Di guard the street pavilion - every move he made was rewriting history, and every "success" was accelerating the unlocking process. But the price came with it: rescuing Guan Yu caused Ma Chao to lose his destiny; rescuing Ma Su made him inflate his self-confidence, and eventually his entire army was wiped out in another battle and he committed suicide. Li Zhao saved him once, but pushed him to a more tragic ending. Every change caused a collapse somewhere else. Then he discovered a fact that kept him awake all night: there was another time traveler in the Wei army camp. Deng Yang - from the same era as him, but fell into Cao Cao's territory. He worked as Sima Yi's scribe for three years, but his unlocking progress was always zero - because he refused to kill people in exchange for the right to return home. The two travelers met for the first time on a sandbar in the middle of the Han River. They reached an agreement: unlocking does not have to rely on killing people. You can find a path that is not a knife edge from every choice made by the opponent. In Jiangling, Li Zhao used the fishing network and system construction to protect a city. Deng Yang was in Xiangyang, using green plums, cold rice balls, three-layer shoe soles and firewood for the common people to spend the winter - pushing the lock open inch by inch. It takes 50% to go home. They were gone for eight years. But at this point - is home still the same home?
