Demon Slayer: I Hand Over the Breathing Style, and the Nation Helps Me Slay Demons

Lin Mo, a first-year university student from Huaxia, wakes up to find that he has transmigrated to the demon-haunted Taisho era, becoming an ordinary person struggling to survive in the world of Demon Slayer.

Demons devour people, and human lives are as worthless as grass. With no talent for Breathing Style and no exceptional swordsmanship, Lin Mo is about to die in a demon's jaws when he unexpectedly activates a "Cross-Dimensional Beacon" connected to modern Huaxia!

"What? You say you encountered a 'demon' that only exists in manga?"

"The Taisho era? Breathing Style is real? The Demon King is called Muzan?"

When Lin Mo reports the brutal truth of this world to his country, including Breathing Style, demons, the Twelve Kizuki, and the existence of the Demon King Muzan, the entire Huaxia leadership is shaken!

A top-secret project, codenamed "Mending the Heavens," is launched in an emergency.

From that day on, the Demon Slayer Corps takes a completely different turn!

While other swordsmen are still training hard in Breathing Style, Lin Mo has already received the optimal training plan from "Dragon's Nest," specially tailored with biomechanical analysis.

While the Swordsmith Village is still researching Nichirin Blades, "special tungsten-steel Nichirin Blades," made with modern metallurgy, are already rolling off the line, far surpassing tempered steel in sharpness and conductivity.

While the Demon Slayer Corps still relies on "Kasugai Crows" for communication, Lin Mo has already equipped the Hashira with "military-grade encrypted walkie-talkies," enabling real-time battlefield command.

Facing the Twelve Kizuki, Lin Mo has the wisdom of an entire nation behind him: "Lin Mo, this is Command. The target, Upper Rank Three, Akaza. The supercomputer has deciphered his Destructive Death: Compass Needle. Evasive maneuvers have been sent to your tactical visor!"

Muzan: "In this era, who exactly is the demon?!"
