Origin Story

话说古代，有个年轻的将军，屡立战功，却恃才傲物，目中无人。他曾率军攻打一座坚城，凭借着以往的成功经验，轻敌冒进，结果大败而归，损失惨重。此后，他依然故我，认为自己经验丰富，所向披靡，不听从任何劝告。最终，他在一次战役中被敌军活捉，身首异处。他的事迹不足为训，后世将领引以为戒，切勿骄傲轻敌。

In ancient times, there was a young general who repeatedly achieved military merit, but was arrogant and dismissive. He once led an army to attack a fortified city, and relying on his past successes, he underestimated the enemy and launched a hasty attack, resulting in a devastating defeat and heavy losses. Thereafter, he remained unchanged, believing in his abundant experience and invincibility, and ignored any advice. Eventually, he was captured and killed in battle. His deeds serve as a cautionary tale, warning future commanders against arrogance and underestimating their opponents.
