The next morning, Shi Chui and the others woke up early. They wanted to see how the main camp would react today. However, to their surprise, there was no reaction at all. Nian Yijiu didn't give the order to attack and everything was normal at the main camp. Furthermore, the people at the main camp woke up late and their training was average. Seeing this, Shi Chui knew that Nian Yijiu wanted to let the people in the main camp rest and recover their strength.
Sieging a city was a physically demanding matter. Even for the soldiers who did not attack, just standing there for a day would consume a lot of their physical strength. After all, they were wearing armor. Standing there for a day without doing anything was a huge test of their physical strength.
