Lin Mo was an ordinary food delivery boy until he discovered that he could see the "qi" in others. The Qi of a rich person is golden, the Qi of a sick person is gray, and the Qi of a dying person is almost completely black.

It turns out that there is another side of this world that ordinary people cannot access.
