The eight peerless geniuses who cultivated 'Primordial Star Conjecture' in the Hunter Cosmic Sector mainly talked about evolution during their gathering.
"Senior Brother Gu Shan, is it really that difficult to increase one's mental strength?" Kabuya asked. "I'm 155 years old, but my mental strength index has exceeded 5,000."
"In the early stages of cultivation, there are all kinds of weak areas in your mind that allow you to improve by leaps and bounds." Gu Shan sat there and smiled. "But the further you go, as your mind becomes closer to perfection, it becomes harder to improve. When I was 500 years old, my mental strength index was already 9123. This year, my mental strength index only reached 9985. It only increased by this much in 500 years."
"It does get slower." Moyu nodded. "After I broke through 9,000, my improvement became slower and slower."
