The next morning, Longwang arrives at his dormitory. He is very ill, and the doctor, Mr. Qu, has brought him back to Longwang's dormitory to find out what is wrong. Longwang tells the doctor that he has come to the future because he is longing for the past, and that the earth is on the brink of extinction. The doctor tells Longwang that the best thing to do is not to eat for three days, because the iron in the body will starve him to death.
