The outpost was situated in the undulating mountains. Zhang Jinglin and Ren Xiaosu followed the sentry and walked along the patrol route. As they stood on a mountain peak along the way, they got a sense of magnificence.
The sentry said to the two of them, "Commander, Future Commander, I can only see you two off to here. Follow the mountain path that I pointed out for 30 kilometers, and you'll reach the next outpost."
Zhang Jinglin and Ren Xiaosu respectively shook hands with the sentry and said, "It's been tough on you."
The sentry smiled and said, "It's nothing."
Zhang Jinglin patted the young sentry on the shoulder and said, "How can it not be tough?"
After that, they parted ways.
