Because...
He will soon be welcoming Mining Star No. 2.
378 light-years away, another mining star is waiting for him.
It's just too far away.
His "wormhole generator" is Level 10, with a detection range of only 10 light-years, so it can only determine within a 10-light-year range which space is relatively stable for wormhole creation.
Before departing.
He needs to upgrade first.
Theoretically, upgrading this accessory to Level 200 extends the detection range to only 200 light-years, but based on his experience, once it reaches Level 200, there will be a qualitative change from "Mortal" to "God," with the detection range definitely exceeding 378 light-years.
The upgrade cost for different Seven-Colored Accessories varies.
Upgrading this accessory costs much less compared to the "Akanon Light Energy Main Cannon," and part of the accessories upgrade up to Level 100 cost the same, only after Level 100 the costs gradually increase.
Upgrade!
