"Life Index?"
Facing Lin Chen's confusion, Ning Xiuzhu smiled and explained: "The Life Index is a comprehensive evaluation parameter used to measure the evolutionary extent of life forms on a planet."
"This index includes many aspects, such as the degree of form evolution, wisdom evolution, level of technology, and so on. In short, the higher this Life Index is, the higher the evolutionary level of the indigenous inhabitants on this planet, and the stronger their combat power."
Lin Chen heard this, and his heart suddenly moved, his gaze expectantly asked: "Dr. Ning, the Heavenly God Clan in the Heavenly God Realm, the human and demon races in the Immortal and Demon Worlds, though their appearances may have slight differences, they are not much different from the Federation human clan. I think there must be some reasons for this."
