The commander of the city noticed the two old men from a distance and immediately stepped forward to stop them: "Hey! What are you two doing? Why do you want to leave the city?"

The two elderly men stopped in their tracks, tears welling in their eyes. The old woman spoke first, her voice trembling with sobs, "Sir, please be kind and let us out! My youngest daughter married far away in Yishui City, and today we suddenly received a letter from her saying she's seriously ill and bedridden. We're so worried, we just want to get out of town and see her!"

The commander frowned upon hearing this, but he still took the bundle from their hands and carefully examined it. Inside were nothing more than some ordinary clothes and dry food, and he found nothing unusual. He tossed the bundle aside and returned it to the two elderly men.

Then the general defending the city called a disguise artist and ordered: "Check carefully whether these two old men and women have disguised themselves!" At this moment, one of the old men inadvertently glanced at the soldier standing next to him and then quickly looked away, but all of this was seen by the general defending the city.

Seeing this, the commander guarding the city became suspicious and turned to question the soldier, "What were you looking at so stealthily just now? Could it be that you know these two people?"

The soldier hesitated for a moment before finally mustering the courage to answer, "Your Excellency, it is true. These two elderly men and I are neighbors, so we usually see each other every day. Today, I felt they looked familiar, so I glanced a few more times. I hope your Excellency will forgive me."

The general defending the city's face darkened and he cursed: "Damn it, if you knew them, why didn't you tell me earlier? I wasted so much effort in vain and I'm so tired!" After that, he waved his hand to let the two old people leave the city to visit their sick daughter.

He said to the two old men with disgust: "Get out!"
