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.

"Hot… but not hot enough." the knight said and flung it's sword towards Laser Ken, stabbing him right in his heart.

Before anyone could react, a black smoke rose out from the sword and it began to cover it's target. While this happened, the other two didn't sit quiet and got even more aggressive against the Knight but none of their efforts bore fruit.

The snake's fangs couldn't penetrate the armor and nor was there any gaps in the armor that it could take advantage of. As for the strings themselves, they were also pretty useless against the knight.

The knight then grabbed the snake with a speed that surprised the two of them. Contrary to it's size, it was extremely fast and the fate of the snake was sealed the moment it was caught.
