Tang Yisheng saw that Quan Shaoqing's expression was frightening and thought something else must have gone wrong.
He immediately moved closer to Quan Shaoqing.
"Tang Yisheng, do you see anything wrong with these corners?" Quan Shaoqing asked.
"What could be wrong with the corners? You can't open a passage there!" Tang Yisheng's eyes darted about. All the corners showed signs of being carved, but nothing seemed amiss.
Suddenly, he noticed one wall was lower than the other three.
Clearly, Quan Shaoqing had already noticed this issue.
He stood in front of the wall, pondered for a moment, and beckoned to Tang Yisheng, "Come here!"
Tang Yisheng walked over, Quan Shaoqing grabbed his shoulder, and the next second they disappeared from the spot. Then they arrived in a pitch-black passage.
They walked through the passage for about fifteen minutes.
