Bab 202: Chapter 201: Tunnel Of Death.

*Step* *Step* *Step* *Step* *Step* 

Countless hasty footsteps echoed throughout the underground subway tunnels. 

Gray ran across the tracks with Violet on his back and Aurora followed after. Violet still hadn't woken up as an after effect of over exerting her energy. 

Gray too was out of juice, he had drained out quite a lot of his own energy in order to find the two. 

The method he used lacked rationality, he stopped time and used X-Ray to search across every nook and cranny of the city. 

He ended up collapsing from exhaustion countless times but even in that situation he'd use it as an opportunity to look around with [X-Ray]. 

Fortunately it ended up working and he ended up finding them. 

But now... 

They had another bigger problem on their hand. 

*Slash!* *Swoosh!* 

Gray passed by a mutated zombie swinging his Katana in the process.
