Science Fiction Evolution: I Am the Only Loophole in Civilization

Rebirth is Li Tanxi's daily life. Relying on the technology of the Civilized Federation, he put his consciousness into the body of every reborn person and traveled around the world. While making money to live, he also discovered something unusual. The world he lives in seems to be false, including himself. The data points given by the system, each person's own abilities, and the bound specialties all look like game characters. The more Li Tanxi delved deeper, the closer he got to his conjecture. I hope it's me who's crazy, not the world. In short, Li Tanxi came to a fork in the road, truth and falsehood. Am I an avatar? Are you a virtual character?
