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

"Fuck yes!" Ethan calmed down and took a few deep breaths to recover. He still tightly held on to Luna and Lia, ready to get the hell out of there any time now but he did not do that just yet.

Soon, another minute passed by, and another one of his minions reached level 25. Ethan kept glancing at the portal entrance repeatedly, fully expecting someone to burst through it but nothing of that sort happened.

Yet he did not let his guard down. There was too much at stake here. He gripped the two tightly as his minions continued their slaughter. Finally, after twenty more minutes the last of his minions hit level 25, that damn freaking worm.

The bastard took its sweet time to get there. But in the end, he managed to pull it off.

You won't slip away again
