In a distant future, Sun Qian finds himself transmigrated to the 30K era, where he becomes an Astartes and awakens a powerful general character card system. His journey takes an unexpected turn on Istervane III, where he encounters Liu Bei, a hero from the legendary Three Kingdoms era. As their paths converge, the course of history in this tumultuous universe is rewritten. The once divided world, now on the cusp of unity, is thrust into chaos by the Horus Rebellion, an event that will reshape the galaxy into three kingdoms.

Meanwhile, the enigmatic Abaddon nurtures his ambition, and the Emperor's own son, Horus, grapples with the weight of his destiny. As the fate of the galaxy hangs in the balance, the heroes of the Three Kingdoms era must navigate the complexities of this new world, forging their own paths and altering the destiny of the stars. With the fabric of reality torn asunder, the question remains: will the resurgence of war ultimately lead to unity, or will the galaxy succumb to the cycle of division and chaos?
