Although the departure of the goblin leaders considerably weakened the goblins' research capabilities, it was still not as neglected as the goblins' previous research into the spatial teleportation array had been. Zhou Tian speculated that if all his craftsmen were thrown into this research, backed by the data left by the goblin race, he should have no problem redeveloping the spatial teleportation array in a short period of time.
This was merely Zhou Tian's speculation, but he was willing to make an effort based on this conjecture.
Zhou Tian now occupied a lot of new territory and digesting these new lands required a considerable amount of time. Given this situation, even if it was only to assimilate these newly acquired lands, Zhou Tian still had plenty of time to wait for the research outcomes from his craftsmen.
