Sometimes people think that lies are easier to be understood than truths, therefore, love becomes contradictory. Because of the chapter "LORD in the forest", PAI ZHI's class arranged an out door activity 'a walk in Spirit Mountain with parents.' But PAI ZHI's mother refuses, as Spirit Mountain is where PAI ZHI's father died. So PAI ZHI secretly plans to go with her best friend XUE YU, and go into the Spirit Mountain. She hopes to find LORD, so she can ask LORD to find her dad that has been missing for a long time.
