Chapter 752: Momentum!
Orochimaru immediately flickered away while thinking, 'Whatever his weird jutsu is, it works by touching his opponents. I can't let him touch me! At least not until I figure out what it does.'
Hiruzen immediately chased after Orochimaru, intent clearly visible on his face. He resolved, 'Ten years ago, I made a grave mistake by letting my emotions cloud my judgment and letting you go. In all the decades I have led this village, that was my second biggest mistake. I can't fix my biggest mistake, but I'll fix this one!'
The Student-Master duo flickered at an intense speed inside the barrier. They were so fast that the Sound Four couldn't even track their movements! Overall, Orochimaru was faster. Unfortunately, he was restrained by the very barrier he raised to trap Hiruzen! Due to the confined space, Hiruzen made steady gains, reducing the distance between them every second!
As he appeared just a few steps away from Orochimaru, Orochimaru used the Hidden Shadow Snake jutsu and launched dozens of snakes at Hiruzen while shouting, "Old geezer! Do you think you can sustain that jutsu forever? How much chakra do you still have left? Just die!"
Orochimaru's prediction was on point. Even though Hiruzen had made a short work of the reanimated ninjas, it wasn't without cost. His chakra reserves had taken a major hit. Even so, Hiruzen grinned and said, "I can sustain it until I fix my mistake, my ignorant disciple! Let me educate you one last time!"
'Fire Release: Yang Demon jutsu'
Hiruzen's chakra suddenly flared and an intense Yang and Fire chakra exited from every chakra point in his body. It immediately transformed into black flames and covered his entire body!
The snakes hit the flames and hissed painfully as they were burnt alive! The fire rapidly spread through their bodies and moved towards Orochimaru, who cut them while retreating. He cursed, "Have you gone senile, old man? You dare to use that jutsu without any protection?"
The black flames around Hiruzen's body not only burnt the snakes but were also burning his flesh. After the Third Raikage created the Lightning Chakra Mode, Hiruzen was inspired to create a Fire Chakra Mode. He gained some successes initially, but soon reached a bottleneck.
