Alex looked at the teleportation array that Zwaka made just now with his new understanding of space. It looked like his Spatial Door. But she didn't need to cross the blue colored realm as he experienced previously when escaping from a Martial King.
It was like Zwaka shortened the distance in that blue colored realm and made it nonexistence. It gave him the ability to teleport people with zero time difference. It was a skill to make a teleportation array.
After Alex learned many things from that crystal, Alex could understand this principle and apply it too. Alex should be able to make a fifty meters teleportation array.
Although it was far from Zwaka's level, at the very least, Alex was in the right direction and could develop his ability with time. Alex thought about enhancing his array mastery. As soon as he could use a Rank 4 Array, he should register in the Array Master guild.
