Nation's Luck: Battle Royale, Summoning Han Xin from the Start

In this battle-royale simulation that will decide whether nations survive, contestants from around the world are burning through their national fortunes, summoning heavily armored knights, legendary gladiators, and Viking berserkers! But with its history lost to the ages, Huaxia has suffered five humiliating defeats in a row and now faces total annihilation. At this critical moment, Su Che takes the stage. Facing a Western army of fully armed heroes, he uses only an extremely cheap amount of computing power in a no-magic, realistic simulation to casually summon someone without even a hatchet for self-defense: a refugee beggar. The whole world laughs at Huaxia. Countless citizens cry and curse Su Che as a sinner for the ages, accusing him of clutching a guaranteed billion in funds and refusing to spend even a single cent! Until... The refugee, kneeling in a muddy pit and on the verge of freezing to death, slowly opens his eyes amid a thunderstorm. He fixes his gaze on the mechanical eye of the Nuwa AI in the sky and rasps out sixteen words: "When the cunning hare dies, the hound is cooked; when the birds are gone, the good bow is put away." The unmatched imperial menace of those ancient words leaves countless top historians at home and abroad on their knees in terror! No one knows that in that fragment of a lost river of history, this man was known as the God of War!
