"Don't move"
Gu Qing Shan hugged Su Xue Er closely and slowly walked from the side of the rail towards the middle part.
He sighed in relief and let Su Xue Er down gently.
-------the area on both sides of the rail were occupied with patches of bottomless darkness, he couldn't infer the distance, nor could he deduce the depth of this darkness.
As for the area above the rail, he could see that the secret passage that guided them to this place gradually extending upwards and leading them further away.
The secret passage and the railway led to completely different locations.
Gu Qing Shan was a bit surprised to see this.
Who could've thought that there was a turning point in the secret passage?
This way no one would be able to reach this place during the same method I did.
