Zhang Gong was somewhat surprised in his heart when Prince Chu said this, but he didn't say much. Of course, he also did not tell Prince Chu how to win the first battle in recovering Shu land. If Prince Chu asked him for advice, he would naturally tell him.
Prince Chu did not consult Zhang Gong on how to win the first battle. He devised the battle plan himself and arranged everything. From start to finish, he did not ask Zhang Gong whether he was doing the right thing.
Zhang Gong was not angry about this, nor did he think Prince Chu was being presumptuous. He also was not worried about it. To him, it didn't matter if Prince Chu lost the first battle because he would eventually win it back. Of course, if Prince Chu won the first battle, that would be even better.
