After Rebirth, I Started to Become Stronger

This is a world where aura and technology coexist. Ordinary humans rely on technology to live ordinary lives. However, some people can awaken their supernatural powers at the age of 16 and become leaders in various industries, especially as demon hunters and soldiers who are active on the front line against the invasion of alien beasts. Due to their abundant spiritual energy, alien beasts have been relying on their powerful bodies and inheritance derived from blood to continue to grow and evolve, invading human living space for generations. In 2020 AD, the male protagonist is reborn with a golden finger: he comes from 30 years later. The battle between humans and alien beasts was originally evenly matched, but 10 years later, alien armies suddenly emerged from the space channel and joined forces with the alien beasts to defeat humans and occupy most of human territory.
