Zhan Taiqing had a clear idea why he was summoned—it was no doubt that Hou Yuxiao was expected to contribute troops to the imminent large-scale battle between the two states!
When Huangfu Xing had left that day, he had issued a military decree, demanding the capture of Wanyang County within a month. Currently, Hou Yuxiao did not fully understand the battlefield situation and only knew that the army of Xingnan Prefecture had besieged Wanyang County. However, he had no clue about the specifics, including how many troops had been deployed.
The entire army of Xingnan Prefecture numbered two hundred thousand soldiers. To besiege a county, at least fifty thousand would be needed, which by the lowest estimate, meant Zhan Taiqing still had an army of one hundred and fifty thousand at his disposal—a not insubstantial force. However, with states engaging in warfare, who would ever complain of having too many men?
