The people of the Dajing Dynasty all have a jade cocoon embedded in their spines. Some people spend their whole lives in a cocoon shell like a stone, and some people see the afterimage of their past life when they break out of the cocoon.
The cocoon of Yu Ru, the subjugated princess, is cracked - on the night when she was seventeen, the national master predicted that the shattered cocoon would cause the heavens to collapse, and the cracks in her spine were spreading silently along with the cocoon patterns on the palms of the Ninth Prince.
Under the bronze palace, glowing vines eat history books. All "accidents" are the threads of fate carefully woven by someone a hundred years ago.
When her cocoon shell completely burst, what came out was not memories, but a rusty key, and three thousand suspended in the middle of the court...
Empty cocoon.
Intention: Those who break the cocoon will eventually become the one who binds the cocoon.
