Bab 109: 109, Autumn Hunt

Having left Prison No. 18, Qing Chen followed Uncle Li Dong through a long tunnel, traversing the prison's surveillance perimeter and walking deep into the mountain.

Qing Chen once asked: why is there a secret passage inside the prison?

Uncle Li Dong explained to Qing Chen: Prison No. 18 was constructed by the Li Corporation.

When the Li Family built the prison, they left a lifeline in case one day their own clan members became prisoners, to prevent dying within its walls.

At that time, the corporation's influence over the Federation wasn't as substantial, and it was possible they could become the victims of power struggles.

Afterwards, the workers responsible for constructing the tunnel, on their way to City No. 10 for another project, all died in a landslide.

Thus, the secret of the tunnel remained known only to a select few within the Li Family.
