Enemy Of An Enemy Is A Friend (4)

The tunnel was just a front to conceal the real staircase leading to the basement. From the outside, it looked like an abandoned mine or something similar, but as Zaen kept walking he saw a light at the end of the tunnel. It took Zaen five minutes of speed walking to reach the end of the tunnel. 

As soon as he walked down the last step, Zaen realised there was another door there. Similar to the one he had seen in the other basement and to the one Zaen had to protect his vault. But it lacked the DNA verification protocol as a security measure.

Instead, the bulletproof door had a scanner attached to it. Zaen immediately took Dr Ravenshaw's keycard and scanned the door. The next moment the door opened with a loud hissing sound, almost as if the door was announcing that someone had arrived there.
