Corridor.
This was indeed a long corridor, its destination unknown.
The earth dog wagged its tail and sniffed around.
"Strange... I always feel like the secret is right here, and we don't need to keep walking along the corridor," it said, puzzled.
"Is that so? Why do you feel this way?" Wu Xiaode asked.
"I can smell the scent of secrets, born into the world as a special form of knowledge, akin to the highest circulating medium in knowledge and information, like gold," the earth dog explained.
Wu Xiaode pondered for a few moments, took out the disk Zhao Congnan had given him, and held it in his hand.
Drip!
A faint sound.
The walls of the corridor flipped over, revealing a narrow passage.
This passage seemed to have sustained some damage and could not open fully, leaving only a slight gap.
Wu Xiaode didn't need to try; he knew he couldn't fit through.
The earth dog tried.
It could pass through.
