The one who had arrived was Minato Namikaze.
"I didn't expect you not to pursue Orochimaru. Now it's two against one. This is getting troublesome."
Minato did not know what had caused Muzan's change in mindset, but mistakes had to be punished.
Having witnessed Muzan use A-rank ninjutsu before, and with Sakumo being Muzan's father, Minato knew it would be difficult to make him surrender through Sakumo alone.
"Flying Raijin!"
Several kunai sealed off Muzan's path, each marked with the Flying Raijin formula. The instant one of them reached Muzan, Minato's figure appeared before him.
"Rasengan!"
Hand-Seal-less Ninjutsu combined with that ghostly speed meant that even Muzan had to face it cautiously. When the attack struck his body, he immediately felt the pressure behind it.
"As expected of the Yellow Flash of the Shinobi World."
"Blood Demon Art! Flesh-Eating Devour!"
The area struck by the Rasengan rapidly healed. At the same time, a hideous, terrifying giant mouth opened, its grim teeth trying to devour Minato's arm.
At the critical moment, Minato used Flying Raijin: Second Stage to leave Muzan's attack range.
After narrowly avoiding it, Minato could not help but be shocked by Muzan's body. Looking at that bizarre form, he asked in surprise,
"Is this one of Orochimaru's human experiments? Or an ability of the Bloodline Limit?"
His gaze fell on Sakumo Hatake, hoping the man knew about Muzan's strange ability. Otherwise, dealing with him would be far too troublesome.
"It is a Bloodline Limit ability, but I do not know the specifics either."
Sakumo was usually away on missions. By the time the war had ended, Muzan had already begun training under Orochimaru. Apart from what he had known during Muzan's childhood, even Sakumo did not know Muzan's true strength now.
A ball of fire descended from afar.
