With his previous experience of shuttling back and forth, it took Chu Nan even less time to pass through the teleportation door. He only used three minutes to successfully pass through the teleportation door and arrive at the Dark Star Field again.
Of course, the difficulty was what to do after this.
From the star map, this Dark Star Field was not especially large. It was roughly an ellipse on the star map, and the longest was less than a hundred light-years. The difference between the top and bottom of the sky was only a mere 30 light-years, and the widest crossing was only 48 light-years. It was almost negligible in an extremely vast Star Field like the Milky Way.
However, to his personal strength, this area was too huge. It was impossible for Chu Nan to search the entire area alone.
