Origin Story
话说三国时期，蜀汉大将姜维率领大军北伐，与魏军在关中展开激烈的对决。双方激战数日，蜀军屡战屡败，士气低落。姜维身先士卒，奋勇杀敌，却也身负重伤，鲜血染红了战袍。战后，姜维被抬回营帐，医师为他包扎伤口，只见他全身布满了刀伤剑痕，没有一处完好无损的皮肤，真是体无完肤。但他依然坚定地指挥着军队，展现出坚韧的意志。
In the Three Kingdoms period, Jiang Wei, a renowned general of the Shu Han Kingdom, led his army on a northern expedition and engaged in a fierce battle with the Wei army in the Guan Zhong region. After days of intense fighting, the Shu army suffered repeated defeats, and their morale plummeted. Jiang Wei, leading from the front, bravely fought but sustained serious injuries, his battle robe stained crimson with blood. After the battle, he was carried back to his camp. The physician examined his wounds, only to discover that his entire body was covered with cuts and bruises, leaving no inch of his skin untouched. He was utterly battered and bruised. Despite his injuries, Jiang Wei demonstrated unwavering determination by steadfastly commanding his troops and displaying incredible resilience and courage.
