School.
On the spacious school playground, many children were playing around, while an elder was cleaning.
This elder had a relatively short stature and a somewhat stooped posture, appearing quite old, as he silently went about his tasks.
At this moment, a white-clad man approached, and the elder slightly raised his head, smiling and nodding at the young man.
"Elder, are you new here?" the white-clad man asked with a smile.
"Been here a few days," the elder replied.
The white-clad man nodded: "A lot of newcomers lately. You're not young, take care of your health."
"I know, I know," the elder nodded, as the white-clad youth walked away. The elder glanced at his retreating figure before continuing with his cleaning.
Meanwhile, outside the school, a young man approached. When he saw the elder cleaning, he paused momentarily, but his gaze quickly shifted away, though his heart remained unsettled.
