In a future city where time is accurately synchronized and "personal standard time" is displayed on everyone's wrist, a hidden price quietly emerges - extreme concentration will consume "concentration time", forming a "lag zone" where time flows slowly, and burdening the parties involved with "time debt".
"Clock corrector" Lu Yun's daily job is to deal with these abnormal areas and rescue debtors. Until he was ordered to step into a giant time lag area that continued to expand and cover several buildings. The core debtor is Chen Lao, an old painter who suffers from Alzheimer's disease and is frantically applying messy colors. The system determines that the old man has fallen into meaningless consumption due to confusion and is on the verge of a permanent "time stop".
However, in the depths of almost frozen time, Lu Yun gradually deciphered the truth: every chaotic color of Chen Lao was using the most primitive way of the human brain to perform a huge calculation - he was reversely deducing the baseline loopholes of the global time system, looking for everyone's original time flow that was quietly "corrected" and "stolen" by the system.
