Origin Story
话说，战国时期，两个国家为了争夺土地爆发了激烈的战争。一方的将军十分凶狠，下令对敌人斩尽杀绝，不留任何活口。士兵们遵照命令，将敌人杀得片甲不留，血流成河。虽然取得了胜利，但这场战争也给两国人民带来了巨大的灾难。事后，将军为自己的行为感到后悔，意识到斩尽杀绝并不是解决问题的最佳途径。他明白了，即使打败了敌人，也要为未来留下希望的火种，而不是将一切都摧毁殆尽。从此，他改变了自己的策略，以仁义为本，致力于维护和平。
In ancient China, during the Warring States period, two countries erupted into fierce war over disputed territory. One side's general was extremely cruel, ordering the complete annihilation of the enemy, leaving no survivors. The soldiers followed the order, killing the enemy until not a single piece of armor remained, and blood flowed like a river. Although they won the victory, this war brought enormous disasters to the people of both countries. Afterward, the general regretted his actions and realized that complete annihilation was not the best way to solve problems. He understood that even after defeating the enemy, a spark of hope should be left for the future, instead of destroying everything. From then on, he changed his strategy and dedicated himself to maintaining peace based on benevolence and righteousness.
