Six hundred years ago, Emperor Yongtai of Dayao launched the "Big Dream Project", integrating his consciousness into the dragon veins and covering the world with twenty-seven air cave nodes, in an attempt to make the Ming Dynasty - no, make the territory of Dayao eternal.
Six hundred years later, Zhou Yu, a young local reporter, removed a dusty cardboard box in a museum that had been converted from an abandoned granary, and discovered a false wall that should not have existed.
Behind the wall is a skeleton that has been kneeling for four hundred years, with a short sword "made in Yongtai" embedded in its chest. The walls are covered with dying words, and the same word is written repeatedly——
"The visitor is inhuman."
A mysterious man who claimed to be from the National Research Institute came to the door: "Your grandfather is the only one who came back alive. You have the blood of the Shadow Guard flowing on your body. The air pocket is about to burst. There are three million people in a radius of hundreds of miles... You are the only hope."
Zhou Yu opened his grandfather's belongings and found a line of words written on it:
"Remember: you are a descendant of the Shadow Guard."
On the more ancient genealogy, cinnabar writing states that only one person in every five generations of the Zhou family can "hear it speak."
Next time, it's Zhou Yu's turn.
That thing had been waiting for him underground for six hundred years.
Now, it's awake.
