Morale was one of the most important factors, whether it was for marching or fighting. It was impossible to win any battle with low morale.
Wei Kang also understood this logic and therefore did not plead for He He. He advised, "Xiao He, the conditions are really hard, but you should think about it. How many people can experience this? The situation is not so bad. You have just come to the wilderness and are currently not used to it. That is all. I have experienced difficult situations before, and I have endured them. With time, you will get used to it. After we get back, we will definitely have a great celebration."
Gao Ke also chipped in. "Xiao He, you saw it too. The road conditions when entering the desert are very poor. Even if someone drives you out, you will be the only vehicle in the desert. What if the car breaks down? What if you roll the car? What will you do if you get lost? Who will save you? It is too dangerous! It's safer to stay with everyone!"
