Zhang Bin shook his head, a glint of wisdom in his eyes, and said, "Dragon Vein Elder, you just mentioned the reasons for the extinction of most intelligent civilizations. What about the others? How did they become extinct?"
"As for the minority of intelligent civilizations, I only have a vague sense that they evolved too slowly to adapt to the changes of Heaven and Earth, and thus perished. After all, the universe itself is changing rapidly. Of course, there were also a few intelligent civilizations that evolved quickly and grew strong swiftly. When disaster struck, they steered their Cosmic Spaceships away from their home planet. Hopefully, they learned their lesson and won't destroy nature after reaching new planets. It seems some of the Three Eyes civilization left this planet aboard Cosmic Spaceships."
"Isn't there a single intelligent civilization that doesn't destroy nature? If so, how did they become extinct?" Zhang Bin asked again, his curiosity piqued.
