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.

[You have only undergone a primary awakening. Secondary awakening is possible, but your body will need some time to properly adapt to the strong primary awakening that you were subjected to.]

[If you undergo a secondary awakening while your body hasn't adapted, the results will be not be optimal. In other words, the secondary awakening will be weak.]

'Hmm... how long will it take for my body to adapt to the awakening?'

[Three years for your body to adapt. Four Years to get the best results from the secondary awakening.]

'Didn't you say that I'll get better results if my body adapts to the awakening? Why would I need more?' he asked mentally and a new message popped up.

[Better than not adapting, but it's not the most optimal.]

Keith understood and nodded to himself. He waited silently for a few hours until Vincent got into an inn with Miya.
