The Fall of Ejaculate

On a cold winter morning,when everyone in the city of Ejaculate was still falling asleep,a young soldier,who tied a piece of string around his left arm,has already set off to the wall from home.
The city has been not peace yet.Though the enemies had gone for about one month,the leader of Ejaculate,was still being cautions to it,perhaps he just afraid of the next attack,so he asked the army to protect the wall instead of making them relaxed.
When the soldier arrived at the wall,another one came to him.
