Doomsday Rebirth Evolution Crisis

When I was reborn before the end, I thought I had a head start. But they were shocked to find that the surviving humans in this life did not develop technology, but had a strange "symbiotic evolution" within their bodies? In panic, I looked at the strange lines gradually emerging on my arms, and a cold mechanical voice sounded in my head: "It was detected that the host is a secondary evolution, and the 'system' is forced to be loaded... The wrong evolutionary direction of human beings is being analyzed." "Warning: You have become the biggest heretic in the world."
