Qin San Lang intended to take in Guo Daming and his group for the sake of Zhang Yan.
Zhang Yan is now following them, but after all, he is not a soldier from He'an Prefecture. Due to the pursuit by Mrs. Jiao, many of his soldiers have died. If they go to the Northwest Camp, and the generals see that Zhang Yan has too few soldiers and decide to split them up, he would lose this ally.
By taking in Guo Daming and his group, they could gather more soldiers, so even if they merge, it would be with soldiers from the same Prefecture, making any undertaken task more cohesive and convenient.
Zhang Yan said, "I want to help them, but you are the leader, and I have not asked your opinion yet. I did not immediately agree with Guo Daming and sent him back first, intending to reply after consulting with you."
