Thanks to Cheng Guang's advance warning, Duke Zhen Guo, Cheng Shiyuan, had long since made preparations. The vast majority of the soldiers in the Northern Expedition Army were arranged to patrol and guard near North City, without being dispatched deep into the Border Area battlefield.
Therefore, it was possible to call back all the soldiers of the Northern Expedition Army to the city at the first sign of trouble, preserving all of their combat strength.
The million-strong Northern Expedition Army was gathered within North City, a sight that was bustling, majestic, and awe-inspiring.
There was not a single person in North City who could not or would not fight.
Should hostilities break out, even an ordinary cook, responsible for making meals, would cast aside their apron, hang up their chef's hat, don armor, take up arms, and ascend the city walls to fight side by side with the Demon Beasts that might attack at any moment.
