Alex was alone going toward the central city. Actually he could use the teleportation device to directly go to the central city but he decided to take the long road to reach the central city. Well, actually he wanted to explore the danger zone and those safe zones before reaching the central city. But there was one main issue. He also wanted to play his game while traveling, but it will be very hard because he won't be able to do both of the thing at the same time.
But fortunately he created a clone and sent him toward the central city. So he is clone already went to the central city but the clone Alex lay low, until the main body didn't arrive.
