"Pan'er, why do you insist on exploring this tunnel so deeply?"
Why?
"Actually, I don't really know why."
Su Pan'er grits her teeth, stepping unevenly as she moves deeper.
They quickly reach a crossroads, the two of them standing still and looking at each other. They finally choose to continue straight ahead.
When they come across another crossroads, they once again choose the middle path. This is repeated over and over.
"Wait!"
Su Pan'er suddenly stops.
"What's wrong?"
"We've been here before."
"We have? How can you be sure?" Qin Yi looks around and doesn't detect any issues.
"Look at the ground."
Following Su Pan'er's indication, in one corner near the wall, they spot a noticeably dried-up wet stain.
"This is the urine of that rascal pig. It urinated here, and I stared at it. But now…"
Su Pan'er didn't continue her sentence.
