Earlier Lu Yuan was concerned about his reputation and didn't want to forcibly conscript local Liang citizens to be cannon fodder, driving them to swarm and attack the city.
But now the Liang people had themselves gathered the individuals together, even turning the original Liang citizens into Liang soldiers, switching from a production unit to a military unit.
With this change of status, everything was fine.
Driving citizens to attack a city was inhumane, the act of a tyrant, and contravened his own reputation for benevolence and righteousness.
But driving prisoners of war to attack a city, that was surely not a problem, right?
Even if the news got out, nobody could really fault him for it.
Over there, there were 240,000 Liang prisoners, and by sending them to the front line to fill the trenches, the Chu State could have 240,000 fewer casualties.
