There were tens of thousands of drones, some of which were drawing star charts tens of billions of light years away, some building bases on desolate dark planets, others setting up posts and factories in space. Now, except keeping their fundamental functions going, they all stopped what they were doing and reorganize themselves to lay a massive communication network in the vast space.
