As he advanced, Jiang Chen found the passage was becoming more and more narrow. In the end, he had to walk sideways.
If he hadn't heard the wind, he would have thought he had arrived at the end of the world.
When arriving at the narrowest part, he had to inhale to move his belly inward to make it through the space, but fortunately, after that, it opened up.
He kept walking. Soon, he saw lights glittering.
He saw a timber bridge leading to a palace, the lights coming from that palace.
Jiang Chen walked to the bridge and looked down. It was too dark to see the bottom. He kicked a stone down and didn't hear it hit the bottom for half a minute.
What an underground world!
Jiang Chen walked to the palace carefully. He released his holy awareness and found there were people in it.
