Xu Haoxin, a young man fascinated by history, unexpectedly transmigrates to the turbulent final years of the Southern Song dynasty. After binding himself to the “Empire Restoration System,” Xu Haoxin gains the power to turn the tide. Rising from humble beginnings, he relies on the System’s ability to “foresee risks” to escape danger again and again amid the chaos, rapidly building wealth and renown. He recruits refugees and forms the “Eagle Army,” training them in “modern military doctrine” to create an invincible cavalry force. Using “technology blueprints” provided by the System, Xu Haoxin produces advanced weapons such as cannons, striking fear into the decaying Song army and the Mongol cavalry. He advances step by step, first pacifying the separatist forces in the south, then leading his troops north to crush the Mongol army and reclaim the realm. In the end, Xu Haoxin establishes a new dynasty, known to history as Great Hua, and becomes a mighty ruler remembered for generations.
