Records

According to the Bamboo Annals,in the 24th year of the regime of Wu Yi, Zhou attacked Cheng (程) at Bi (毕) and defeated Bi.

According to the Bamboo Annals,in the 30th year, Zhou attacked Yiqu (义渠) and captured the king of Yiqu. According to Sima Qian, the King of Yiqu has two sons by different mothers; after the king died, they fought each other for throne only to have Zhou defeat them both and absorb the territory of Yiqu.

In the 34th year of Wǔ Yǐ's reign, King Ji of Zhou came to the capital to worship and was rewarded with 30 pieces of jade and 10 horses.

In the 35th year of Wǔ Yǐ's reign, Ji attacked the Guirong (鬼戎) at Xiluo (西落). According to Sima Qian, he captured 20 kings of that tribe. In the same year, Wu Yi went hunting between the Yellow and Wei Rivers and was killed by lightning. According to the Book of Documents, this was blamed on Wu Yi's grave impiety. Once, he was supposed to have carved a wooden statue of "the God of Heaven" and had one of the priests to represent it 令人為行. He played liubo with the idol and had it lose three times in a row, then destroyed it. Another time, he filled a leather bag with blood and hung it high in the air, then shot it with arrows; he called this "shooting Heaven". He then blasphemed by saying the god of thunder and lightning was nothing.

生平

商王庚丁駕崩後，武乙即位。商仍居殷都。

武乙狂傲，藐視神權。他曾經製作一個人偶，稱之為「天神」，並與人偶博弈，命人替天神出子。結果「天神不勝」，武乙便用刑罰對人偶加以侮辱。武乙又命左右用皮革製作一個囊袋，裡面盛滿血，懸吊于空中，拉滿弓，仰天射它，說這是「射天」。

《後漢書》關于東夷的記載中提及武乙與東部民族的狀況：「武乙衰敝，東夷寖盛，遂分遷淮、岱，漸居中土。」

武乙在位期間，西方的周族首領古公亶父率領族人從邠地遷居岐山，周族逐漸強大。武乙將岐邑賜予周公。武乙三十四年，周公季歷前來朝見，武乙賜給季歷土地及玉、馬等物品。次年，季歷討伐鬼方，俘虜二十狄王。

一天，武乙到黃河和渭水之間遊獵，天空中突然電閃雷鳴，武乙遭雷擊而死。子文丁即位。

從甲骨文和殷墟祭祀坑的年代來看，黃組卜辭時期的人牲祭祀和牲畜祭祀都很是少見。而黃組卜辭所對應的是文丁、帝乙、帝辛時期，這時平均每年所殺的人牲還不到兩個，人祭規模不僅比之前的時代小了許多倍，甚至比後來的西周時期還要小。雖然武乙時期可能還有偏多的人牲祭祀，但武乙時期的卜辭中只有一位貞人，貞人數量相對于其他商王少很多，其在位期間可能確實有變革。武乙之死至今是一個謎團，武乙可能是一個改革者，想要使政教分離，得罪了眾多巫師，于是這些巫師醜化了他的形象，編造出「武乙射天遭雷劈」的謊言。有些學者推測，武乙是在渭河、洛水之間戰死或病死的。
