There is such a group of people who wander in the darkness and protect the common people with their own abilities. Some of them can hide from the enemy, some can find the dragon's acupoints, and some can pinch and calculate. They are the unsung heroes behind the scenes, working silently without asking for anything in return. When you are in danger, they may appear in front of you immediately. When you enjoy the sunshine, they are fighting against the darkness. They only have one unified name: Ling Yi Ke.
