Chen Fan had seen quite a lot of planets that became barren in the universe. Many planets filled with life had existed for billions of years and their Spirit Qi had been used up by the Immortal Cultivators.
All of those planets had survived at least a few billion or even ten billion years. They were birthplaces of countless civilizations of Immortal Cultivation, and had plenty of Grand Cultivators and Saints, who were all famous across the universe.
But Earth was different.
Earth was a young planet. Its civilizations hadn't even existed for a few thousand years. It was quite energetic and should be able to be active for countless years, nurturing generations of Immortal Cultivators.
But at the moment, it seemed that the Spirit Qi on Earth would disappear forever in the span of a century. There wouldn't even be Foundation Establishment Cultivators, let alone Grand Cultivators.
These planets were known as "Eternal Sleeping Planets" in the universe.
