Deep underground in the Ancient Books Restoration Center, there is an unknown "treasure room". Chen Wan's ink works with insects, water stains and torn pages every day, using the temperature of his fingertips to awaken the sleeping ink marks. She thought it was just a craft that was about to die out, until late one night, when she put a new green sandalwood paper cover on a incomplete "Collection of Heroes of Heyue Heroes" from the Tang Dynasty, a line of hidden bloody words on the back cover suddenly shone brightly, "Anxi Protector's Mansion, trapped."
The ink stains collapsed like chains, black air burst out carrying the smell of sand and rust outside the Great Wall, and a hoarse alien voice sounded in her head.
