Li Chen traveled through time and became a hostage of the Yan State, just as the Qin army was pressing on the border, the Yan State was on the verge of death. He suffered humiliation and activated the [God-level Strategy System] in a desperate situation. He took advantage of the system and proposed a crazy plan to "surprise the Qin army's food and grass" when everyone was optimistic about it, but was ridiculed by Zhang Kuang and others. He risked his life and led the remaining soldiers to implement the plan, burning the company camp overnight, defeating the Qin army and saving the Yan state. From then on, he rose from a proton who could be bullied by others to become the military god of Yan State. After establishing a foothold in Yan State, he began to gather forces, develop the economy, and prepare for war to strengthen Qin. In the end, he will lead the Yan State (or the new force he established), fight back to the Qi State, fight against the King of Qin, aspire to dominate the world, and rewrite the script of history.
