There is one thing I don't understand. Why do soldiers leave the company to send messages?

Because the recruits have gone through three months, as long as they have experienced it, they will sigh, and the daily training tasks are fully arranged, because this is the beginning of the soldiers and the first foothold when they first arrived in the army. And I'm about to join the job, and I can't bear to be separated from my classmates. These three months' life is full, with joys and sorrows. So, send it back.
