Shen Lang, executioner B-774 of the Space-Time Administration, is ordered to travel to the Tang dynasty and capture an illegal transmigrator whose path to wealth has been suspiciously abnormal.
But what seems like a straightforward arrest soon reveals a shocking conspiracy that could topple the Space-Time Administration, along with a terrifying source of corruption capable of making the world itself "sick."
When the law enforcer and the transmigrator are both marked for elimination by a higher-level group of "cleaners," and the wheels of history are about to fly off the tracks because of an unseen hand...
The former cat and mouse have no choice but to become teammates, fighting a silent war against enemies from the future on the real battleground of history.
This is a battle of wits spanning a thousand years.
My weapons are neither blades nor guns.
They are the rules themselves, engraved into the laws of time.
