In the 21st year of his reign, the
Zhou leader
Koufu () died. According to the
Bamboo Annals, in the 24th year of the regime of Wu Yi, Zhou attacked Cheng () at Bi () and defeated Bi. According to the
Bamboo Annals, in the 30th year, Zhou attacked
Yiqu () and captured the king of Yiqu. According to
Sima Qian, the King of Yiqu had two sons by different mothers; after the king died, they fought each other for the 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 () at Xiluo (). 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. Wu Yi's death is still a mystery; it has been speculated that Wu Yi may have been a reformer who wanted to separate church and state, and
priests as a retaliatory action scandalized his image and made a fabricated record that "Wu Yi was struck by lightning when he shot Heaven". Some scholars speculate that Wu Yi died in battle or died of illness between the Wei River and Luoshui. According to the
Records of the Grand Historian, he was supposed to have carved a wooden statue () of "the
God of Heaven" and had one of the people throw dice to represent it. He played
liubo with the
idol and if the idol lost the game, he humiliated 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". ==References==
