Dao of the Bizarre Immortal

Story:

High school student Li Huowang possesses an ability: whenever he closes his eyes, he enters a bizarre cultivation world. In that strange world, he is captured by someone who calls him "Master" and is made into a living medicine—a human cauldron that could be turned into a pill at any moment. In the real world, however, Li Huowang is a mentally ill patient living in a psychiatric hospital, unable to attend school. The doctors tell him that the bizarre cultivation world is nothing but a hallucination. Now, caught between reality and illusion, truth and lies, Li Huowang breaks down, crying and shouting: "Mom, I really can’t tell what’s real anymore!"
