Although the Overseas Continent offered significant benefits, Zhou Tian was very clear that even with potential advantages, they were not easily seized. From his observations, Emperor-level forces already existed in the Main Plane, and contact with them suggested that annexing their territories might be even more challenging than taking over Ancient Ruins Space.
The Demigod that appeared before Zhou Tian indeed possessed considerable strength, but in his view, that strength amounted to no more than a leader without troops. Unlike Monsters whose clans' strength would increase altogether with an upgrade, for the remnants of the previous Epoch, being powerful merely meant personal strength. Theoretically speaking, even a Demigod leading a group of ordinary living beings was a possibility if there were no special reasons and the beings themselves were unambitious.
