Shield of a Great Nation: Spies Forbidden Beyond This Point in Jiuzhou

After transmigrating to the Great Wu dynasty from the modern world, Yu Ji finally fulfills the conditions to activate the System after eighteen years. He joins the department responsible for national security: the Hundred Cavalry Bureau. Right from the start, he acquires the god-tier tracking skill, Bone Tracking. Thus is born a God of Death who strikes terror into the hearts of enemy spies and informants.

Bone Tracking: a trail as faint as a snake's tracks in ash, yet there's nowhere to hide!

Knife grappling: within arm's reach, I am invincible!

Bursting force: with a single step, I can shatter the heavens; concentrate all my power into one point and reach the pinnacle!

In the name of the Hundred Cavalry Bureau, he keeps traitors who collude with the enemy and endanger the nation awake with fear.

As a mere martial artist, he forces the entire martial world to keep its head down.

Someone once said, "The deeds of a good spy are all written on their tombstone."

But through his actions, Yu Ji makes one indisputable fact clear to the enemy:

"Great Wu lies ahead. Spies, keep out!"
