He needed to complete Zhuge Liang's Northern Expedition under the requirements of the system. However, he had a problem at the first step, and the system asked him to continue to divide his troops on the mountain! He originally thought this was another cycle of failure, but the barrage in front of him told him that he seemed to have a way to win, so everything changed!
