With Mortal Bones, I Reverse-Engineer the Secrets of Heaven

Lu Yifan, a child from an ordinary family, missed the chance to go to college due to a 2-point gap in the college entrance examination. He was bound by the word "difficulty": family trouble, money trouble, and road (future) trouble. Because of a fragment of the "Book of Changes" left to him by his grandfather, he met his master by chance. On the tea beach, the master gave him advice on the word "trap" written by him. Hexagrams are not used to tell fortunes. "The hexagrams heal the heart, and daily use is the way." Can he get out of trouble? What kind of life path will he embark on? "Gather your strength when you are sleepy and wait for the breakthrough."
