The secret item!

The group had made a decision, and it was to head back to the Reborn group, which was run by Sarah Bain, one of the two creators of the zombie apocalypse. It was one of the safest places for the group currently, and on top of that it was the place that would most likely help them find the whereabouts of Zain.

Getting there was no easy task though, since they would have to travel through multiple territories. As time went on, zombies of higher stages were being seen more frequently, but it also meant that the group could also grow stronger.

As they travelled through multiple areas, they defeated the high stage beast with their teamwork, and with the crystals they continued to absorb their power through the technique that Zain had shown them.

All of them could feel themselves getting stronger, this included Skittle as well. He too was able to absorb crystals, so he increased his strength and power even without Zain's use of the system.
