Midnight.
John was going to sleep when suddenly, Evelyn came and said in a serious tone," John I can sense a huge number of undead are approaching us. At most within ten minutes they will come to our location."
As soon as he heard her words, he immediately rushed out and said in a loud tone," Everyone Alert. Take your position."
John's loud voice is enough to make his soldiers awake. Knowing that they would face a night attack the soldiers didn't dare to sleep. Moreover, they had also done such drills. So they immediately got up and climbed on the wall. As for those walls, John always felt unsafe so he built them before sleeping.
Fortunately, he did so, or else they might be in trouble now.
John climbed on the wall and he waved his hand. Suddenly the Night Lit plant began to grow all over the wall. The whole place was illuminated. This made the soldiers relieved. At least they won't have to worry about the sneak attack.
