Lu Yuan naturally didn't know that the people in the Safe Zone were filled with envy, jealousy, and resentment.
He simply spent a full month becoming familiar with the robust body endowed by "Extraordinary Level 2."
Lu Yuan also sincerely cultivated the "Extraordinary Spark" left from the Meida Civilization.
One of the benefits of possessing a civilization's heritage was that he didn't need to painstakingly conduct his research; it could be used readily—even though the Meida people and humans have very different body structures, many principles were actually the same.
The Meida Civilization had evolved for over three hundred years and possessed a well-established system for talent education and scientific research.
This information was enough for Lu Yuan to study for a very long time.
The Level 2 Extraordinary Spark was even more powerful, being able to partially release Ideal Energy externally and thus evolving many more application techniques.
