Seven days remained until the countdown to genetic mutation. Seven days later, all creatures on Earth would undergo mutations. Giant mutated creatures would swarm and attack humanity, putting their fate in jeopardy. The entire Earth would be ruled by these mutated beings! Yang Xiao accidentally walked into a genetic store where various gene potions were sold, capable of altering human body functions. From that moment on, he embarked on a crazy journey of genetic evolution.

Keith, a regular office worker from Earth, suddenly transmigrates to the world of the novel he had been reading for the past decade. The new world, which was also called Earth, was slightly different. People with various powers existed who were called awakeners, making this world comparatively dangerous and also mysterious. While he was thrown into the novel's world, he was also given a mystical ability to grant systems to other people. Armed with his special ability, he slowly climbs up the power ladder by taking "taxes" from the people he would give systems to. The only question that remained, was what would a realistic normal man, when faced with a similar minded protagonist, do when their goals opposed each other.
