Lu Yi didn't know about Xie Rui's previous experience and only wanted to quickly bring him out.
Soon, the two of them arrived outside the prison.
From the map, there was a big door behind the prison. From there, one could leave the city.
However, this door was very well-hidden. Other than a few authoritative figures in the city, no one else knew about it.
The two of them ran for about one hour before they reached the back door indicated on the map.
It was a stone door that could not be pushed open at all.
Xie Rui was so tired that he leaned on the ground to catch his breath. He said in a low voice as he panted heavily, "There must be a mechanism around here. Look for it carefully."
Lu Yi searched around the exit and finally found a mechanism to release the trigger. She pressed the mechanism down. Rumble! A small crack suddenly appeared on the sturdy city wall in front of her and the stone door swung open.
