As for the Three Bodies, who destroyed such a powerful civilization?

The Three Bodies was a Chinese story about the exchange and conflict between the civilizations of Earth and the Three Bodies Galaxy. The Three Bodies Civilization was believed to have been destroyed by the Earth Civilization. In the novel, the Earth civilization and the Three-Body Civilization gradually discovered each other's strengths and weaknesses through communication and gradually established mutual trust and friendship. However, by the time the leaders of the Three Body Galaxy decided to invade Earth, Earth's civilization had already begun to develop its own technology and military strength, and it had sufficient defense capabilities. In the end, the Earth civilization defeated the invaders of the Three-Body Galaxy in the space war and ended the conflict with the Three-Body Civilization. Although the novel did not explicitly mention which specific country or race destroyed the Tri-body Civilization, it could be speculated that the development and powerful strength of Earth's civilization might have led to conflict and war with the Tri-body Civilization, which eventually destroyed the Tri-body Civilization.
