Advertising Space for Rent in All Worlds

I can see everyone's ads. But they didn't know that the thing that placed the ads... Was also staring at me. When I woke up, I was lying in a pile of corpses with 7 personalities living in my head. I don't know who I am, I just remember looking for someone. Then I met a madman. He piled a mountain of corpses, sang folk songs, and held a silent bell—— When the senior sister died, "Killing the master and attaining enlightenment will reward +100 years of cultivation" popped up in the sky. He said that the advertisement was placed by the system. I met a 600-year-old mage, a 300-year-old demon, a broken god, and a tombkeeper who remembered hundreds of names. They are all awakened ones. They are all people who are "stared at" by the same thing. But I saw it written on my medical record: The spiritual fragments of 7 people are put together to form one person. My name is Lin Shen. I'm looking for someone. But recently I started thinking: That thing that's been staring at me—could it be looking for me too?
