Lin Shen bought a broken watch for ninety-nine yuan at the flea market. He thought he could just tell the time, but it started to display future news.
"Three days later, a blue car hit the guardrail on Donghua Road."
He thought it was an hallucination, but when he arrived at the scene, he saw the blue car rushing towards him out of control.
In order to save a little girl in red clothes, he changed the future for the first time - and heard the sound of "time splitting" for the first time.
From that day on, his life completely went astray.
The "time slot messenger system" behind the watch was activated, and he was forced to become a time courier traveling through ancient and modern times:
Send life-saving medicines to doctors in the Republic of China, deliver key blueprints to World War II scientists, and bring future warnings back to the past.
But every delivery is accompanied by the pursuit of time correctors, the backlash of time paradoxes, and more and more "foreign objects" swallowed by the cracks.
But Lin Shen gradually understood——
Time cracks are not natural disasters, but wounds left when humans try to control time in the future.
And he is the chosen "sewer".
When global cracks expand, the time plague spreads, and history is tampered with by multiple forces, Lin Shen must find a way to repair the structure of time without destroying the past and future.
But he doesn't know that the real enemy has always been hidden in the deepest part of time.
This is a story about time, choice and cost.
It is also a story about an ordinary person who bought the entire future of mankind with ninety-nine yuan.
