The Difference Between Soul and Yin and Yang

My name is Li Tian and I am a rural Feng Shui master. Since I was a child, I have been able to see things that others cannot see - the souls that wander at the intersection of yin and yang. The car accident three years ago should have killed me, but the Lord of Hell said that my yang life was not over yet, so he gave me a pair of yin and yang eyes to make me a yin and yang. From then on, I showed people Feng Shui during the day and collected Yang Qi from the underworld at night. The last breath of every dying person will turn into a wisp of smoke in the copper bell around my waist.
