Nightmare Freakist: My Clients Are All Weird

[Traveling through a different world + system upgrade flow + no heroine + slow pace, not invincible] When he woke up, Lin Zimo, a modern high school student, traveled to a different world where weirdos and humans coexisted, steampunk and the occult intertwined. He was adopted by a mysterious and inhuman being and became his apprentice. For three years, he learned how to sneak into the dreams of insomniacs and nightmare-ridden people and weave peace for them. However, the peaceful life came to an abrupt end after the teacher went out for three months and did not return. In order to survive, and to find traces of his mentor, Lin Zimo had to carry the name alone and use the knowledge and props left by his teacher to become a wandering dream therapist. His clients are diverse: from insomniac nobles to monsters tortured by nightmares, word of mouth spreads quietly. Until he accepted the invitation and left the town for the first time to treat severe insomnia. It was here that he ran into six Blue Star fellows who behaved strangely and had names like game IDs suspended above their heads. After the mission at the Baron Manor ended, a brand new world opened up in front of Lin Zimo. He was not the first time traveler. He fully realized that this world was closely connected with the world he was in. In order to unlock the secrets about himself, he resolutely left the small town where he had lived for three years and embarked on a journey across the continent to find his master. "As someone who cannot be mentioned, cannot be described, cannot be looked at directly, and cannot be described, your mystery makes me yearn for it."
