PS: This book is purely fictitious and any similarity is purely coincidental.
Relaxed and humorous, the plot is slow-burning, so proceed with caution!
Have you ever thought that there are a group of invisible and intangible "things" around you?
Have you ever thought that when you are sleeping soundly at night, there is someone beside you silently guarding you;
Have you ever thought that there are some people who are invisible to you, fighting various powerful "enemies" in order to maintain world order?

Luonan was originally a very ordinary college student, but due to an accident, he opened another door to the world. From then on, he was a student during the day and a warrior at night, fighting against various "powerful enemies" just to protect the beauty in his heart.
Who says those who stand in the dark are not heroes!
