Origin Story
话说古代某朝，奸臣当道，皇帝昏庸，朝政腐败。奸臣李某，凭借皇帝的宠信，只手遮天，结党营私，贪赃枉法，鱼肉百姓。他一手遮蔽了朝廷，官场之上乌烟瘴气，民不聊生。百姓敢怒不敢言，只能暗地里痛恨他，无奈之下，只能向苍天祈祷，希望上天能降下神兵，惩治这个祸害百姓的奸臣。然而，李某却对此浑然不觉，依然我行我素，继续着他那只手遮天的暴行，直到他被正直官员揭发，最终被皇帝处死。
In ancient times, a corrupt official controlled the government through his influence over a weak emperor. The emperor’s favor allowed this official to accumulate power, form factions, engage in corruption and bribery, and oppress the people. His reign was characterized by injustice and exploitation, leaving the people powerless and only able to pray for divine intervention. The official, however, remained unmoved and continued his tyrannical rule, until he was eventually exposed by a righteous official and executed.
