"Why can't I see the flow of chakra or any hand seals?"
Kakashi's expression turned grave. After throwing three kunai, he did not immediately throw the remaining few. Instead, he stood below and calmly observed Haku.
In Kakashi's established understanding, Hand-Seal-less Ninjutsu did exist, but such techniques still required the flow of chakra.
"It's as if they appeared out of thin air."
As one of Konoha Anbu's elite, Kakashi possessed exceptional battlefield analysis skills. With just a brief exchange, he could estimate his opponent's strength and the powers they excelled in.
There was never any shortage of geniuses in this world. Muzan had already begun to make a name for himself at that age, and Haku before him had the same potential.
With Muzan's help, Haku's growth rate might even surpass his own.
Standing in the snow, Kakashi felt a biting chill slowly creeping over him. As time passed, the situation would only worsen. He had to end this quickly.
"Phew!"
The breath he exhaled carried white mist. Kakashi rapidly formed hand seals, gathering chakra together.
"Fire Release: Great Fireball Technique!"
The flames drove away the wind and snow. Haku, standing ahead, did not panic as the massive Fireball Jutsu drew near.
As the distance closed, the flames gradually shrank until they vanished completely, without stirring even the slightest ripple.
"It's useless. My ice and snow cannot be dispersed by flames."
"I only need to kill the target of my mission. I don't want to kill you."
The wind and snow once again concealed Haku's figure. This time, Kakashi felt immense pressure. His opponent was even stronger than he had imagined.
Merely relying on the surrounding temperature was enough to extinguish flames.
"What kind of power is this?"
Perhaps his flames simply were not strong enough to reach the opponent.
