The fourth-tier civilization is the Civilization of Seekers, living and dying within a day, due to changes in time.
The fifth-tier civilization is the Space Realm Civilization, beginning to master space. This level of civilization has already begun to master the technology of space construction, space jumping, etc.?
The survivors' camp on Earth was in utter amazement.
However, thinking about it, it's reasonable. After mastering the time of the human body, next comes the space of the human body... the concretization of the mind's spatial awareness into a physical space?
Everyone secretly pondered, finding it very mysterious.
"So, what about the sixth tier?" Amiro asked unceremoniously.
Bailong hesitated for a moment. The fifth tier hadn't even been surpassed, and yet they were thinking about the next realm?
Nevertheless, he answered honestly,
"That was a true level only present when our ancient ancestors were alive."
