It's not impossible to use this city as a permanent base; Chen Ming can use it as a bridgehead for communication with the Empire.
If something goes wrong and they get attacked, at worst he can just run and abandon this place.
After all, he found the city in the first place, so losing it wouldn't be painful.
Besides the Mechanical Race, the Insect Queen should also continue to stay on the planet to grow.
Such a large habitable planet with no inhabitants means its entire resources can be utilized.
With more time for the Thorn Insect Race to grow, Chen Ming doesn't know how far they can develop.
And there was another reason that led Chen Ming to this decision.
When the Insect Queen was recasting the Insect Nest a few days ago, he discovered something extremely unique about the Hive Mind.
All individual consciousnesses in the Hive Mind do not only exist within their bodies but also within the Hive Mind Network.
