This is the Cosmic People's "Black Curtain" plan.
They have now deciphered many oracles of the Cosmic Gods, learning of the mysteries and dangers within the cosmos, and they are deeply fearful, even going so far as to establish such a massive project in an attempt to completely wrap the entire Cosmic Star System in a black curtain.
However, while some choose to hide, others seek to uncover the mysteries of the cosmos.
At this moment, on the edge of the star system, several spaceships are rapidly navigating through space. These are all medium-sized ships equipped with curvature engines. Once they escape the "black curtain", they can quickly enter a state of curvature navigation, permanently leaving this closed and dark world.
Unfortunately, it's not that easy.
A thousand identical ships are in hot pursuit.
