Zain and Skittle followed Kun without knowing where he was taking them. Along the way, they hunted any mutated zombies they came across, and at the same time, Zain was also experimenting.
Through killing Zombies, or at least mutated ones, he found out that if he or Skittle were involved in killing a mutated Zombie, he would gain exp, and there would be no crystal. However, if Kun killed the mutated zombie, there would always be a crystal.
Zain did want to analyse the crystal, but Kun seemed to be quite possessive of the crystals he gained and placed them in a little pouch inside his suit's blazer. Zain had a thought, or more like a theory, that maybe if he touched the crystal, it would tell him what he needed to do with it to gain exp or at least a new set of information.
