During the three months when Jiang Lu led his troops in person, Yan Country was destroyed, but the resistance was particularly fierce throughout the process.
Those loyalists summoned by Zhou Ding not only refused to surrender but also attacked brutally; one could indeed describe them as truly loyal, and the solution was quite simple—kill them all.
Otherwise, what was the point of keeping them?
After the annexation of Yan Country, naturally, it was time to set sights on Xi Country and Zhou Country.
Many families from within Xi Country came forward wanting to surrender, but Jiang Lu's attitude was ambiguous, mostly just dragging his feet.
For Jiang Lu, preparing to take action did not mean immediate action; at the very least, he had to fully assimilate all the territories of Yan Country first.
Otherwise, it was very easy for rebellion to ensue.
