If Zhou Tian is to construct a large number of universal spatial teleportation arrays, his foundation can indeed be laid solid at that time. However, when it comes to establishing those spatial teleportation arrays, Zhou Tian still faces many difficulties. If Zhou Tian doesn't have a good strategy, it would be very difficult for him to construct those spatial teleportation arrays.
Of course, the reason as to why Zhou Tian has such an idea, naturally has its roots in his considerations.
At least at the beginning, Zhou Tian never thought of building spatial teleportation arrays himself. Although he possessed several spatial teleportation arrays, those were relics passed down from several epochs ago. More than half of them are now inoperable. For those operational ones, Zhou Tian has no way of moving them, hence, their usefulness is confined to his territory.
