Demon Slayer: Nuclear Breathing, Every Draw of the Blade Is a Nuclear Blast

[System + scheming + dimensional outclassing + lighthearted comedy + never takes things lying down]

Lin Xuan transmigrates into the world of Demon Slayer and becomes Tanjiro Kamado's good-for-nothing senior apprentice from the start.

He slacks off and sleeps every day, and can't even be bothered to do the basic training of a thousand sword swings.

Sakonji Urokodaki cries out in anguish: “If you go down the mountain like this, the demons will eat you!”

Tanjiro's imagination runs wild: “Senior Brother is so lazy, he must be secretly testing me!”

Lin Xuan rolls his eyes and silently summons the [Atomic Breathing Style System].

As long as he collects other people's emotion points, he can unlock nuclear-physics superpowers without limit!

Other people train in Water Breathing or Flame Breathing and nearly die just to cut off a demon's head.

Lin Xuan simply activates [Nuclear Breathing] and gives this backward world a little taste of physics!

[First Form: Critical Slash]: The blade is coated in fusion heat of over ten thousand degrees. He doesn't even need to draw it. He merely pushes the blade out half an inch, and a Lower Rank demon instantly vaporizes!

[Second Form: Nuclear Blast Surge]: With a casual swing of his axe, a miniature nuclear blast plows the ground, leveling a mountain peak dozens of meters high and leaving behind a crater of molten glass!

[Nuclear Radiation Field]: Standing still with his hands in his pockets, he creates a high-pressure radiation field within a five-meter radius. The demons that approach can't even touch the hem of his clothes before disintegrating at the atomic level!

And that's not all: [Isotope Mark Tracking], [Microscopic Atomic Manipulation]... Killing demons is like crushing an ant. Whether he grinds them to dust or makes them explode on the spot is all up to a snap of his fingers!

And so, the entire world of Demon Slayer goes completely off the rails.

Shinobu Kocho: “My poison-coated Nichirin Blade was held between two of his fingers and burned into steam?!”
