Origin Story
话说三国时期，蜀汉名将姜维年轻有为，深受诸葛亮的赏识。他跟随诸葛亮南征北战，屡建奇功，也因此积累了丰富的作战经验。一次，蜀汉军队与魏军在祁山爆发激烈的战斗。姜维临危不乱，指挥若定，运筹帷幄之中，决胜千里之外，最终以少胜多，大败魏军。他之所以能够取得如此辉煌的战绩，正是因为他身经百战，积累了丰富的经验，才能够在战场上做出正确的判断和决策。后来，姜维屡次带兵出征，每次都能取得胜利，他的名声也越来越响亮，被人们称为“身经百战”的英雄。
During the Three Kingdoms period in China, Jiang Wei, a young and promising general of Shu Han, was highly valued by Zhuge Liang. He followed Zhuge Liang on numerous campaigns and achieved repeated victories, accumulating rich combat experience. Once, a fierce battle broke out between Shu Han and Wei armies at Qishan. Jiang Wei remained calm and collected, making strategic decisions that led to victory. He ultimately defeated the Wei army with fewer soldiers. His brilliant record was due to his vast experience from numerous battles, allowing him to make correct judgments and decisions on the battlefield. Later, Jiang Wei led several more expeditions, achieving victory every time, becoming renowned as a battle-hardened hero.
