章節 208: Silver Heart Passage

The exploration of the Observation Terminal was nearing its end. It had a very special background.

From the looks of it, there were civilizations that had built such a monitoring device in the Milky Way before humans had made their mark.

Their purpose was unknown, and it was also unknown whether they were still a civilization. The only thing that was known was that they did come from beyond the Milky Way.

However, the humans managed to hack into the surveillance camera and left a backup plan.

Now, Li Wenyuan could use this planetary machine to monitor the entire Milky Way, which was something that the giant sentinel array with similar effects could not do.
