Chapter 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.

It was just a pity that if he had met this monitor earlier, then his pace of exploring the galaxy would undoubtedly be much faster.

The root of everything was still the missing active purification agreement.
