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.

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!”
