Eternity: God Mechanic

Kraynnor, a genius who appears once every thousand years, was subjected to ridicule due to his obsession with attaining immortality, an obsession that seemed to squander his innate talent. Finally, at the age of eighty, he managed to double his lifespan. However, his desire to share this achievement was thwarted by a devastating alien invasion that wiped out humanity. Aware that there was no turning back, Kraynnor decided to take possession of the genetic information of billions of humans, as well as the corpse of a fallen alien in combat... He took refuge in an undetectable underwater laboratory, where he spent five hundred years perfecting a new body that fused human DNA, alien DNA, and advanced technology. Now, with the genetic information of billions of humans, his new body, and his unparalleled intellect, he was determined to extract the life essence from every invading alien to create a new species, which he called 'Superior Humans'. Of course, he was not willing to forget or forgive anyone involved! He was ready to take revenge, even if it meant erasing all forms of life in the universe!
