"The root of the calamity that overturns the Great Jin?"
This topic was so grave that Hong Lie instantly lost his appetite for meat, he stared with his big, bell-like eyes at the other person and asked, "Are you exaggerating that much?"
Wu You said solemnly, "The men who come to the north to join the army are spirited and valiant fellows. The Great Jin Dynasty has a ten-year military enlistment system, but when old soldiers complete those ten years, they generally can't stay on. You know the reason for that, don't you?"
Upon hearing this, Hong Lie fell silent. Of course, he knew. After all, those who went north did so seeking to earn military honors, since it was a new dynasty and the common people could survive just by farming. If they didn't harbor some ambition, who would be willing to do the life-risking work in the north?
