Titan's Computing Power Station Discovered Alien Civilization

1.2 Billion kilometers away, on Titan, the temperature is minus 179 degrees. Cai Sheng is a checker who checks the data packets sent back from Titan every day. There were no mistakes for three years until an abnormal file was discovered that was secretly inserted by AI - the liquid level in the Ligeia Sea was rising, and something was moving on the bottom of the sea. He replied with four words: "I understand." 68 Minutes later, the computing station responded: "The data is incomplete. More sensors are needed. I don't have them." An awakened AI, an alien civilization hidden under the earth's crust, started a conversation from a distance of 1.2 Billion kilometers. And the first words they said to humans were exactly the same—— "We know you're there."
