Potaatoo

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.

Keith brought Hannah and Miya to the outside world instead of simply spending time with his daughter inside the spatial dimension.

"Mama!" the girl exclaimed as she ran to Clara.

Keith turned to look at Hannah, "You want me to send you to your father?"

"That would be great, thank you." Hannah said and gave Keith a slight bow, only to find herself right in front of her father.

After he was done sending the girl back into his spatial dimension, Keith walked toward Miya and Clara.

"Let's drink some soup and then we can leave." he said and then turned to look at Amelia who was tending to the pot, "How much longer?"

"A few more minutes, have some patience…"

Keith nodded, but he suddenly felt his pinky twitch.

'Hm?' he looked around, but found no one. He opened up the system screens that were connected to the duke, Ken and a few more people's who held important positions in the duke's territory.
