He took a deep breath, Zhang Yuan manipulated the screen, and saw the next data point: this star domain was a dense intersection area of Cosmic Strings, essentially the central location of a spider-web distribution of Cosmic Strings.
This meant that near the Dyson Sphere, it was possible to use gravity-assisted travel.
If you think about it, it isn't surprising; the locations chosen for the interstellar trading markets are almost always areas with very convenient transportation.
Not only must the Fourth-level Civilizations, which have achieved warp speed, be able to reach the trading market, but you also have to consider the Second-level Civilizations and Third-level Civilizations that can only travel via Cosmic Strings. Only when these lower-level civilizations are able to come here is it considered a successful market.
"Using Cosmic Strings for interstellar travel is considered a basic method, right?"
