My Experience Is Actually the Player's Sanity

After traveling back in time to the game he made, Gu Yuan originally thought that the situation was stable. As the chief planner, he can pass levels with his eyes closed. Until he discovered three things: 1. His upgrade experience = the player's San value consumption. 2. Players think they are playing the ninth art, but they are actually being cut off by him. 3. Something is tampering with his game - the plot is heading towards an ending he never designed. In order to survive, Gu Yuan raised the sickle with tears in his eyes.
