The night they reached the war zone, the Emperor had dinner with the soldiers that improved his favour among the troops. That day their troops had suffered some losses and the Emperor sitting with them eating the same food they eat with the same cutlery they use helped them quell some of the doubts they had about this war.
They had realised that the moment the Emperor had stepped foot in this place, the rain had stopped and there wasn't a single drop of rain from then on. Usually, most of the soldiers in their kingdom are superstitious and believed a lot of sentiments. At first they were skeptical about the Emperor's presence because there was a firm belief that the presence of the Emperor in the battlefield will bring disasters with the Tianshi Emperor as the exception.
But this Emperor who is said to be coronated by the God of Wind himself seems to be different and has good fortune following him. They really felt good about the battle tomorrow.
