Local Netizen Elf's Life In Another World - Case 108: Almost smartphones.

On an ordinary day, Lucius stumbled upon a strange, run-down shop. At first, he assumed it was abandoned—until he stepped inside.[You have entered the Universal Alchemy Store.][Congratulations! You are now the store’s owner.][Please craft your first potion.]Lucius blinked. 'What kind of joke is this?' But as if guided by an unseen force, he followed the instructions. Minutes later, his first creation was complete.[Love Potion: The drinker will fall in love with the first person they lay eyes on.]Lucius swallowed hard. 'Wait… does this actually work?'Before he could process it, the shop’s door swung open.Standing in the entrance was no ordinary customer—she was an elf. Long, pointed ears, mesmerizing green eyes, and a body sculpted by the gods. A visitor from another world.A dangerous thought crept into his mind.'Should I test it on her?'

I had to take him home and raise him. There was no bathtub or a large basin at home, so I had to put him in the washing machine for the time being.

It was an hour later before I remembered it again, by which he had been washed extremely clean.

Kellen Woods grew up never knowing a normal world. By the time he could walk, his mother and father had already sealed several serious gates that threatened the safety of his hometown. By the time his sister was born, they were famous worldwide.So the world held their breath for when Kellen and his sister came of age, waiting to see what kind of power they would awaken.His sister was just like his mom, same power, same class, while Kellen, woke up one day to find out what it meant to be special in a family the world watched. But in the worst way.Awakening weaker then your powerful parents wasn’t unheard of, but when your younger sister awakened at the same class as your parent, anyone would feel inferior. And Kellen, never one to ask for hand outs, left the comfort and safety of his hometown to become better than the weak brat everyone thought he was.Kellen went to the front lines, to where the gates normally broke out. From there, Kellen worked hard, and then worked some more until no one could doubt that he was good at his job. He got so good that even with his lower class, people would still hire him to help. But Kellen never took it to heart. He had learned a valuable lesson on the front lines. Classification only meant shit if you walked back out of the gate. Otherwise, shut your mouth and listen to those with more experience. They determined who made it out alive or not.But Kellen was tired now. He had gotten everything out of his system, and the fast paced life on the front lines didn’t suit him anymore. Now, he wanted to go home, buy a house, maybe find a nice man to settle down with, and live a normal life.All the while, the yellow eyes he’d met on the front lines haunted him, no matter how much he tried to forget about them.Especially since the Esper they were attached to refused to let him go.
