There are also Jiang Ziya, King Wen and King Wu in the Romance of Gods. Why didn't he help the Duke of Zhou, who became king?

The Duke of Zhou was mentioned in the original work of Romance of the Gods. Duke Zhou is Zhou Wenwang's fourth son and Zhou Wuwang's younger brother. In the tenth time in the original book, there is a passage: Ji Chang arranged to sing a song in the imperial court the next day, and suddenly arrived at the scene, leading fifty followers. I saw Sanyisheng, Nangong General, Mao Gongxiang, Zhou Gongdan, Zhao Gong, Bi Gong, Rong Gong, Xin Jia, Xin Mian, Tai Dian, Yao Hong, Four Sages and Eight Commandments, Prince Boyi Kao, Ji Fa and other civil and military officials leading all the soldiers and civilians to Shili Pavilion to bid farewell and host a banquet in Kowloon (cited). In addition, it is also mentioned in the final data packet.

It's rarely mentioned in TV series, because the main content mentioned in "The List of Gods" is the battle among the Three Realms, which is about Jiang Ziya's destiny takes a hand to help and Zhou Wuwang to cut the Zhou Dynasty. The plot mainly tells the detailed process and cause and effect of cutting Zhou, which has nothing to do with Duke Zhou.

As we all know, Duke Zhou was famous for assisting Zhou Chengwang. After the establishment of the Western Zhou Dynasty, in order to consolidate the Western Zhou regime, he carried out a series of political and institutional reforms, determined the far-reaching eldest son inheritance system and the enfeoffment system, and carried forward the Zhou ceremony. These achievements were basically achieved after the establishment of the Western Zhou Dynasty, and the Romance of the Gods mainly talked about things before the establishment of the Western Zhou Dynasty, so it is normal to rarely mention the Duke of Zhou.
