The awakening of a world is simply the world facing a great catastrophe that cannot be easily overcome. This was like a trial of passage where, if you survive, your world will be added to the universe.
The current earth has yet to become part of the universe. So, for now, if it were to be discovered by an alien race, they would call it an Outer world.
But the moment it awakens, it will be known as a True World.
Old Lu had read about this awakening and even heard of it many times in the past, so when he received his memories, the first thing that came to mind was the awakening.
It usually happens within the first 100 years of the apocalypse. Earth is still young in this regard, but he knew deep within that the rules wouldn't apply much this time.
But instead of panicking, he instead started placing all his dreams and aspirations on the one person the Ancient Monks back in the day spoke highly of.
The one they called the Paragon.
