Nightmare Oddity Master: All My Clients Are Supernatural

[Transmigrated to Another World + System Progression + No Female Lead + Slow-Paced, Not Overpowered]

After waking up one morning, modern high school student Lin Zimo found himself transmigrated to another world where humans and the uncanny coexisted, and steampunk intertwined with the occult.

He was taken in by a mysterious, inhuman entity and became its apprentice.

For three whole years, he learned how to enter the dreams of insomniacs and those plagued by nightmares, and weave them a sense of peace.

But his peaceful life came to an abrupt end when his teacher went away and failed to return for three months.

To survive, and more importantly, to find his mentor, Lin Zimo had no choice but to take over the signboard himself. Using the knowledge and tools his teacher had left behind, he became a traveling dream therapist.

His clients came from all walks of life, from sleepless nobles to monsters tormented by nightmares. His reputation quietly spread by word of mouth.

Then he accepted an invitation to leave town for the first time and treat a severe case of insomnia.

There, he encountered six Blue Star compatriots behaving strangely, with names floating above their heads like game IDs.

After the mission at the baron's manor was over, a brand-new world opened up before Lin Zimo. He wasn't the first person to transmigrate, and he realized completely that this world was closely connected to the one he came from.

To uncover the secrets surrounding himself, he resolutely left the town where he had lived for three years and set off on a journey across the continent to find his mentor.
