Zane had decided to head west into China proper. Rather than attempt to make his way to North America. Which at the moment was an impossibility for him. However, there was just one problem with this goal of his. He was currently in South Korea. Or what was South Korea prior to the collapse of human civilization?
If he wanted to enter China, there were really only two options. First, he could go back through North Korea. But considering the stir he had caused when he escaped from Pyongyang, walking through the entirety of North Korea without getting caught.
Well, that was easier said than done. Which left one other option for Zane and his merry band of misfits. He had to go west, through the Yellow Sea in order to reach the shores of China. There were, of course obvious risks involved with this.
