Minato Namikaze was not confident he could kill Muzan either. According to their research, Man-Eating Demons could not be killed through physical means.
Left with no choice, they had resorted to sealing techniques.
Of course, Minato Namikaze possessed ninjutsu capable of dealing with him, such as the forbidden Dead Demon Consuming Seal. But given the current situation, if he died in battle, it would be a catastrophic blow to Konoha.
He had powerful means at his disposal, yet could not use them.
At the very least, he had to get Haku off the battlefield. He could not let the enemy use his abilities without restraint and turn Konoha into a frozen world.
A Flying Raijin brought him directly to Haku's side. Compared to the battle-hardened Pakura, Haku was somewhat inexperienced in this regard. At the very least, he was no match for Minato Namikaze.
But one must not forget that Muzan was beside him.
The instant Minato Namikaze appeared at Haku's side, Muzan reacted immediately, sweeping his ninja blade forward.
The blade passed through the air, preventing the kunai from landing on Haku.
Yet as the two brushed past each other, their gazes met. The moment Minato Namikaze threw out the first kunai, another kunai arrived before Haku at the same time.
"Flying Raijin: Second Stage!"
This kunai successfully pierced Haku's neck, and blood immediately flowed out. But Haku paid no attention to such a wound. He simply pulled out the kunai, and the wound healed at once.
"Just as expected, he has immortality too."
The Flying Raijin's use was not limited to assassination. Since he could not kill Haku, he could only send him away from the battlefield.
The mark on the kunai landed on Haku's shoulder. It was an imprint engraved into flesh and blood.
