Rumble.
A massive roar echoed endlessly inside the Four Violet Flames Formation!
At times, the tremendous force of the explosions even made the barrier walls of the Four Violet Flames Formation bulge and warp!
Kabuto Yakushi, Jugo, Guren, and Tayuya, the four people maintaining the Four Violet Flames Formation, had long since lost the ease they had shown earlier.
At first, they had kept their doubts to themselves, but in their hearts, they had wondered if Orochimaru was making too much of a fuss over one demon by going to such lengths to target it.
But once the four Hokage truly engaged Tanjiro, they understood the reasoning behind Orochimaru's elaborate preparations.
They even felt that these preparations might not be enough!
Inside the barrier.
With a swish, the Third's body was sliced in two by the Scarlet Blade in Tanjiro's hand. Yet almost immediately, the Third, an Impure World Body, began to recover.
The Scarlet Blade in Tanjiro's hand could indeed suppress the body's ability to heal. Even with immediate treatment using Medical Ninjutsu, wounds inflicted by the Scarlet Blade were extremely difficult to heal.
Unfortunately, though, none of those Tanjiro faced now had flesh-and-blood bodies.
They were merely Impure World Bodies that could continually regenerate. So although the Scarlet Blade in Tanjiro's hand remained sharp, it had lost the terrifying lethality it had shown against ordinary shinobi.
Rumble.
The next moment, a violent explosion erupted on Tanjiro's body.
As it turned out, the Third had deliberately let himself be cut apart.
As the Ninjutsu Professor, he was exceptionally skilled at taking advantage of every opportunity. So he exploited the fact that an Impure World Body had no fear of injury, deliberately closing in on his opponent and sticking Explosive Tags to Tanjiro while Tanjiro was cutting his body apart.
