Forging a World-Destroying Demon Weapon, Starting with Dragon Clan

Li Ye was dumbfounded. One second, he was clinking glasses and eating hot pot with his girlfriend; the next, the world spun, and when he opened his eyes, he had become Tanjiro in the Demon Slayer world!

Before he could process the shock of changing identities, the [Strongest Demon Blade System] slammed straight into his mind:

"Ding! Host successfully bound! Kill demons to earn emotion points and grow infinitely stronger! Draw any ability from the myriad worlds!"

From the start, he drew the god-tier template "A-Ju-Ra-Maru," and a demon blade that amplified his strength appeared in his hand!

Li Ye gripped the hilt, his gaze instantly turning cold. So what if this was the Demon Slayer world? Anyone who dared ruin his date was going to pay. He'd cut down every demon here to vent his anger!

"Tanjiro's body? Perfect, just right for killing demons." He whispered to the air. "Let me borrow your determination to save Nezuko and your burning desire for revenge!"

From that day on, the Demon Slayer world gained a rampaging "Tanjiro":

Every swing of his sword rang out like Chidori, and he pursued demons with Flying Thunder God teleportation;

He unleashed One-Sword Asura at full power, filling the blood mist with demons' screams;

The Thousand Demon Blade shattered into a rain of light, while Bankai, Domain Expansion, and Unlimited Blade Works took turns crashing down on his foes. Even the Hashira stared in shock!

Kibutsuji Muzan was hacked full of holes, his blood running cold with terror. Clutching his head, he howled, "You're not Tanjiro! You're a demon blade wearing human skin! Stay back!"

Li Ye sneered and spun the demon blade in his hand. "Scared now? Too late. Today, you'll learn what it feels like to be hunted from the myriad worlds all the way into the Demon Slayer world!"
