A sci-fi future story with a small amount of quick transmigration and System creation. A calm, powerful, ruthless top X a strong bottom who grows over time. HE, primarily from the bottom's perspective.
On the day Ji Yunshen arrived in the First Realm, Professor Jiang gave him a course list. It included Introduction to System Theory, Common Cultivation Techniques, and the Laws of Space and Time...
Ji Yunshen: "..."
He immediately turned left as he left the building and called the interstellar psychiatric hospital hotline.
"Hello, I've been kidnapped by a mental patient."
"All right. What is your exact location?"
"He says this is the First Realm."
Click. The other party hung up.
That idiot. The First Realm's infamous, terrifying Jiang Min, the great demon king who had countless Systems at his mercy, smiled at him. "Go on, try running away."
