When human geological energy detection technology broke through to a depth of 20,172 meters underground for the first time, achieving a historic record of exceeding 20,000 meters, a new energy source, later named "earth core", appeared in front of the world. With the continuous exploration and research on the unknown substance "earth core", humans have discovered that "earth core" diluted to a certain extent can be easily absorbed by the human body. Compared with water, the human body craves "earth core" more. When the first batch of people who took "Earth Core" destroyed a heavy armored vehicle with their individual strength, proving that "Earth Core" can fully develop the potential of the human body, the whole world was shocked... When a large number of people over 150 years old appeared in the human race, and the number continued to increase, people began to realize that this world was different. Later, at a special time point, the Vita Alliance officially faced the world, confirmed that potential development has a leap-forward effect on extending human lifespan, and announced its preliminary system concept to all mankind. At that moment, the world went crazy... At this point, human society entered a new era.
