The middle-aged man had always suffered from kidney weakness, and his last name was Zhang, so everyone called him Zhang Laoxu.
Zhang Laoxu grunted, "Of course, it's true, haven't you noticed? I'm different now."
Zhang Laoxu straightened his back.
The crowd laughed, "What's different about you? Could it be that just by going in, your chronic kidney weakness was cured?"
Upon hearing this, Zhang Laoxu scolded, "Are you blind or something?"
"Have you ever seen me able to stand up like this in broad daylight?" Zhang Laoxu pointed at himself, seemingly boasting.
The crowd looked over, and he had indeed pitched a tent.
"For real?"
"Damn, I thought there was no such thing as a free lunch."
"Who would have thought Zhang Laoxu's kidney weakness could actually be cured."
"Shit, that's an old problem of his, right?"
"Isn't that so?"
"This can be cured too."
Zhang Laoxu snorted, "If I hear anyone call me Zhang Laoxu again, I'm going to lose it."
