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 spent the next two days adjusting his mindset. Not that it helped. He eventually gave up and moved on, deciding instead to start building himself back up again from scratch. He had advanced to the next rank, and now it was time to explore exactly what he could do.

"Arcane Synthesis…" he muttered thoughtfully, raising his hand. With a mental command, he summoned Shadow, who materialized from a swirl of dark mist, its sleek black fur shimmering under the daylight.

Ethan studied his cat carefully, anticipation building in his chest. This was the first skill he intended to test—a skill capable of inducing mutations. The potential excited him. If this worked, his minions could evolve beyond their current limits, unlocking new strengths and abilities.

He took a deep breath, focusing on the skill. Mana surged through him and he could feel a deep connection to the cat. But at the last moment, he disrupted the skill and did not allow it to activate fully.
