Yolohy

Ethan wakes up expecting to see the walls of a hospital room—only to find a system message blinking in front of him:
[Ding! You have killed a green worm]
[Ding! Green worm has been added to your summoning list]

Anything he kills becomes his to command?!

Ethan finds himself in a brand new world filled with magic and power. Awakened with an SSS-ranked class, he rises to power by conquering everything that stands in his path. While other summoners struggle with their dozens, he gathers millions as his army. There is no limit to how much he can grow, but he quickly realizes that forbidden power doesn't come without consequences.

Limitless Summoner: Rise of the Soul God

Ethan looked at his hands again, his grin widening. This was just the beginning. There was still fire, wind, earth, metal, blood, and whatnot. He was going to become the fucking avatar and he loved it.

"This is what I am talking about." He did a fist pump. What is the point of magically popping into another world if he couldn't summon fire or ice at command?

With renewed enthusiasm, he started practicing again and again. The water spell was easy enough but it was the spirit magic that was giving him the most trouble. He ended up staying awake late in the night and practicing.

By the time he was ready to sleep, it was already early morning. He dragged his tired body downstairs and headed for the morning chores. The old hag was surprisingly nowhere to be found so he walked into the study and started moving the dust flakes.

I am very bad at it. Trust me.
