QIANG JIN JIU

During the Xiande period of the Great Zhou Dynasty, Lord Shen Wei of Jianxing was defeated at the Chashi River in the northeast, which nearly resulted in the loss of six central provinces. His son Shen Zechuan was taken to the capital in disgrace, despised as the son of a loser. Xiao Chiye, the youngest son of the Lord of Libei, rushed to the capital at the news, and nearly beat Shen Zechuan to death. However, the weak-looking Shen Zechuan fought back fiercely, and even bit Xiao Chiye until he bled. It was the start of a fierce feud between the two. Unexpectedly, during their endless conflict, they accidentally discover the real reason for Shen Wei's defeat.
