Chen Xi rubbed his chin and said first that his long-standing assessment was that the Huns were relatively intelligent this time, so they knew the gravity of the situation. Because of this, Chen Xi's assessment was that the Northern Huns would significantly increase the defense of their own tribe.
Similarly, based on this, Chen Xi had not considered the possibility of the Northern Hun's main tribal defense being bolstered by other tribes. However, after Zhou Yu brought it up, Chen Xi started pondering the idea.
"Indeed, it was my oversight. I only considered the Northern Hun's caution but ignored their current weakness in military power. Though using other tribal forces to guard their tribe carries the risk of exposure, it's a more practical approach," Chen Xi said, tapping his finger lightly as he spoke slowly.
