From ancient times to today, there have always been many young people, raised in luxury and never having experienced the harshness of war, who harbor unrealistic and naive fantasies about the brutal combat between individuals.
After reading a couple of military books and practicing martial arts for two years, they think they are a reincarnation of Sun Wu or Lv Bu, invincible in the world...
When large quantities of firearms are deployed on the battlefield, many old age armies often initially hold a disdainful attitude toward them; they prefer to trust the swords in their hands and the armor on their bodies.
Then they realize that the issue is not whether their swords are sharp or their armor is heavy, but rather that they cannot see the trajectory of bullets with the naked eye, nor can they touch the people shooting beside them.
Inexplicably, suddenly dead, like crops harvested in batches.
