Volume 6, Chapter 9: Signal Fires Blazing Everywhere

In the autumn of the seventh year of Great Yong’s Longsheng era, in the twenty-first year of the sixty-year cycle, the Yong Emperor denounced Southern Chu for going too long without paying tribute. He decreed that the King of Southern Chu present himself for an audience. When the King of Southern Chu heard, he became frightened out of his wits. He abdicated, citing illness, after many days not holding court. When the Yong Emperor heard, he was furious. He vowed to his troops to march south. The armies departed on three routes simultaneously, and war resumed.
