Under the strict surveillance of the quantum satellite, Yan Fei firmly grasped all movements within a radius of nearly eight light years centered on Earth. As soon as there's a stir within this range, the artificial intelligence "Dream" will immediately know and transmit the intelligence to Yan Fei.
In the universe one light year outside Earth, at a position 100 million kilometers from the outer edge of the Solar System's Oort Cloud, there was a quantum satellite launched by Yan Fei. This quantum satellite had been stationary for a long time, with its detection capabilities activated, scanning the starry sky within a radius of 100 billion kilometers and constantly monitoring all movements in this area.
