First of all, it is the emperor's personal bodyguard who plays a protective role. These well-trained bodyguards only have eyes for the emperor. The emperor will try his best to make the personal bodyguard understand that as long as you follow me and be loyal to me, you will be popular and enjoy all the splendor. However, once the personal safety of the emperor is harmed, the life of these bodyguards will be difficult. Therefore, these bodyguards will try their best to protect the emperor in case of danger.
Secondly, there are strict rules and regulations in the military camp. The emperor was protected almost 24 hours a day. At night, the army often has generals patrolling. You are not allowed to walk around the barracks at night unless you have something important to deal with. There are often secret sentries around the barracks. If anything happens, the horn will sound, and all the soldiers will be ready to go, close to the camp where the emperor is.
Ministers and camp strategists often discuss together in the evening to ensure that the emperor is foolproof. Emperors who use personal expedition are often used to boost morale. The emperors who really came to power to kill the enemy were very few emperors immediately. To put it bluntly, the emperor's personal expedition is equivalent to improving his image in disguise and gilding himself, so that historical records can leave a great image for future generations. In that case, the emperor's safety will naturally be no problem.
