I often read war novels. Many war horses cannot be killed. It should be that war horses and weapons were the most important things of the ancients at that time. For example, if there is a knife, if it breaks, people will die, if the horse is there, people will die if the horse dies. These two things belong to the most precious things of soldiers and also to the closest comrades. This should be understood. Do you think you won by losing all your guns in modern warfare? Life-saving things are scattered, so are ancient times and ancient people.
