In 2500 AD, as scientists endlessly explored the universe, advanced creatures in the depths of the universe became aware of the existence of the Earth. For unknown reasons, alien creatures launched a massive attack on the Earth, resulting in heavy human deaths. After the war, the Earth's star core erupted with a magical gas that could make Earth species stronger. Scientists named this gas Tianqi, but humans' ability to absorb Tianqi is very limited. Therefore, scientists developed a nanochip called Qixin, which can make people Humans absorb Tianqi at a faster rate, and can also rely on this chip to extend human lifespan. However, human scientists are not satisfied with this. They once again combined with alien species to create a combat nanochip that can possess the special abilities of alien species. Relying on this type of combat chip, humans finally defeated alien creatures, and humans were able to survive. However, alien creatures did not stop attacking humans, so the earth abolished the national system, and the Qixin warriors took the lead in creating an organization called the Dimension Federation to resist alien creatures.
Purpose: Save humanity and fight high-dimensional creatures
