"Let me see..."
A young man looked at the tablet in his hand and murmured, "The system shows that seven years ago, a cosmic landmine was shot down in this area, which means there was another civilization explosion."
"That's normal."
"The system is set so that the cosmic landmine only targets those whose radar range reaches 100,000 light-years. That's the hallmark of a third-level civilization. It won't bother a fourth-level civilization, and a third-level civilization shouldn't have the means to shoot down a cosmic landmine."
"Alright."
The young man looked at the progress bar on the tablet that was already completed and tapped the "Explore" button in the corner of the tablet. A virtual radar appeared on the screen and began to quickly explore all civilizations within a radius of 1 million light-years.
This process was relatively slow, taking several minutes.
The completed progress bar was him receiving the "travel log" of the cosmic landmine before its death.
