Guo Jing was originally an ordinary senior high school student. When his grandfather passed away, he inherited an ancient sword and an ancient book on "Spiritual Art". It turns out that grandpa's true identity is a spiritual craftsman who walks in yin and yang.
From then on, the supernatural world hidden in the shadow of the city opened its door to him.
On the first and fifteenth day of the lunar month, hundreds of ghosts walk at night;

While other spirit craftsmen were still attaching plush toys to the souls of cats and dogs, the ancient sword in his hand was sleeping with two ancient sword spirits that shocked the entire spiritual world - the pair of white eagles who followed Beixia Guo Jing back then.
"With your level of cultivation, do you deserve the name Guo Jing?"
As mysterious weapon spirits and thousand-year-old fox demons appeared one after another, Guo Jing gradually discovered that a mysterious power was sleeping within his body. While dealing with evil spirits that kill innocent people indiscriminately, and at the same time trying to find out the truth about his grandfather's death, can this young man named "Guo Jing" truly become a "great knight" in this yin and yang world full of treachery and conspiracy?
