The thread-twisting artisan Luo Nian is accused by the Broken Bridge's main tendon of being the tendon-pulling culprit, and line-patrol inspector He Jiao is ordered to investigate. Guided by the second-hand line dealer Cao Chou, the two enter the Weaving Heart Tower, discovering that the light-silk memories of the entire city are being rewritten. In the bright weaving city, light-silk records everything and can also be tampered with. From opposition to alliance, Luo Nian and He Jiao fight against the automatically operating Weaving Heart Tower. Three main tendons, future memories, the taken-away father—clues twist layer upon layer. Seven days later, the reboot is approaching, and Luo Nian must choose between forgetting and the truth. Who pulled away the names of the entire city, and who pulled the bridge's tendon?
