Sakonji Urokodaki stepped forward, his gaze fixed on the test tube, his breathing growing somewhat rapid beneath his mask.
"Will the injection be dangerous?" Sakonji Urokodaki asked.
"Arcana Power is extremely overbearing. It will force its way into her cells and clash violently with the demon blood in her body. Only under its suppression can the antidote truly take effect and break down Muzan's cellular structure." Rokuya pulled the protective cap off the front of the test tube, revealing a sharp needle.
Rokuya crouched down and took Nezuko's arm. Nezuko was asleep, but her muscles still retained a demon's toughness.
Rokuya's gaze sharpened, and he precisely inserted the needle into a vein in Nezuko's arm. He slowly depressed the plunger, injecting all the liquid in the test tube into her body.
The instant he withdrew the needle, Nezuko's body jolted.
Nezuko, whose eyes had been tightly shut, suddenly furrowed her brow and let out a muffled groan of pain. The veins on her arm bulged instantly, and black demon markings flickered beneath her skin, trying to resist the foreign power.
Pale blue light began to move across the surface of Nezuko's skin. The aura of Arcana Power erupted in an instant, firmly suppressing the black demon markings that tried to fight back. The two forces clashed fiercely within her body.
Nezuko's body began to convulse violently. Her hands clutched the wooden boards beneath her, her nails gouging deep scratches into them.
"Hold her down. Don't let her hurt herself," Rokuya said gravely.
Sakonji Urokodaki immediately stepped forward and pressed both hands firmly against Nezuko's shoulders, holding her in place.
The clash lasted a full ten minutes. Ultimately unable to withstand the absolute suppression of Arcana Power, the black demon markings began to recede bit by bit along her blood vessels.
