Song Changming is a Fire Patrolman in the Patrol Armor Bureau. He has a special system which enables his Lifespan to increase everyday. Initially, he had no great ambitions. After accumulating a hundred years of lifespan while lying low, he only wanted to rise step by step in the Patrol Armor Bureau, to live better in glory and wealth.

As for practicing martial arts or pursuing the Tao, all these began when he threw away that ring in which lives an old spirit.
