Lai Min wanted to say something else, but Zhou Yu vetoed it. Without even confirming the enemy's strength, thinking of persecuting potential allies is not normal. It's better to wait until we've truly felt the strength of the Huns before discussing anything else.
Lai Min felt somewhat resentful, but once Zhou Yu makes a decision, apart from changing for Sun Ce, others hoping to alter it is wishful thinking.
Zhou Yu was completely unaware, because of the eagle scouting matter, he felt that after coming to the north, he knew himself but not the enemy, and did not agree with Lai Min's strategy. Otherwise, given the fighting power of the Wuhuan, they would be directly crushed by the Northern Huns Cavalry.
Similarly, given the combat power of the Eastern Wu Infantry, once without allies, even with Zhou Yu leading, the infantry would still lose to others. This is a practical combat power gap, and there's nothing more to say.
