"Get ready to be purged by the Will of Fire." Nagasawa's momentum exploded, and a huge golden flame began to gather around him, melting the ice and causing the temperature to rise rapidly.
"Impossible, how did you suddenly become so powerful?" Kaguya no longer had her indifferent look on his face as it was replaced with astonishment.
She couldn't fathom how Nagasawa suddenly became so powerful. As an ordinary person, reaching that level was considered impossible. And now, Nagasawa had gotten even stronger. His strength increased dramatically to the point of surpassing her in terms of raw power.
This shouldn't happen, and it couldn't happen.
Without Otsutsuki bloodline or becoming Ten-Tails Jinchuriki, just an ordinary person—why was he stronger than her, a member of Otsutsuki Clan who had consumed Chakra Fruit?
At this moment, Kaguya was shocked, jealous, a bit afraid as well.
She was shocked by Nagasawa's sudden change, jealous that an ordinary person like Nagasawa could become so strong that he could reach a level she couldn't achieve even after consuming Chakra Fruit, and afraid of being sealed again, and this time, it might be forever.
"So strong!" Upon sensing the intense aura from Nagasawa, Naruto was also shocked. He didn't expect Nagasawa to still have another trick up his sleeve even after his battle with Madara.
As expected of the Fourth Hokage!
"This momentum, could it be..." Unlike Naruto and Sasuke, who were surprised at Nagasawa's immense strength, Kakashi thought of something else.
He used Nagasawa's Chakra to open other dimensions, and they had already opened four dimensions. Logically, Nagasawa's Chakra should be almost depleted, so why was it even stronger than before?
Kakashi speculated that Nagasawa had used some sort of a Forbidden Technique similar to Eight Gates, judging from the powerful effect. The side effects could be extremely severe, possibly even leading to death.
At this moment, Nagasawa became a person worthy of Kakashi's respect.
The Fourth Hokage from another world had come to their world for unknown reasons. Because this world also had Konoha, he was willing to fight for Konoha of this world even though it wasn't his own world.
To achieve the ultimate victory and protect this world, he was willing to use Forbidden Technique with potentially severe consequences as long as he could keep fighting.
"Lord Nagasawa, you are a great Hokage," Kakashi said respectfully.
Even though Nagasawa looked very young, even younger than Kakashi, he still addressed him with "lord" because Nagasawa deserved his respect.
Nagasawa realized that Kakashi had good eyes. Kakashi saw through him with just a glance. It was a pity that he couldn't bring in recording devices to teach Kakashi from his world a thing or two.
Whoosh!
Suddenly, enormous ice spikes emerged from all directions, surrounding Nagasawa.
Facing such power from Nagasawa, Kaguya set aside her sense of superiority over ordinary humans and exerted full control over this world.
As the master of her dimension, Kaguya possessed the power to manipulate all the natural forces inside it.
"Using ice against my fire?" Nagasawa asked with a mocking smile. It seemed that his previous punch wasn't enough to show Kaguya how strong he was; it was necessary to show her the power of his Supernova Mode.
Ignoring the ice spikes from all directions, Nagasawa floated calmly in the air, looking down on Kaguya, just like how Kaguya looked down on mortals.
Being looked at by Nagasawa like this, Kaguya felt uncomfortable. Refusing to be outdone, she floated into the air, surpassing Nagasawa in height, and used her abilities to manipulate this dimension again, and countless ice spikes bombarded Nagasawa.
Naruto wanted to go help Nagasawa, but he was stopped by Nagasawa.
"You and Sasuke should focus on finding an opportunity to seal Kaguya. No need to help me. A mere Kaguya Ōtsutsuki can't possibly harm me," Nagasawa said lightly as he ignored the incoming ice spikes.
Whoosh, whoosh, whoosh!
The next moment, the golden flames surrounding Nagasawa suddenly surged and rapidly spread in all directions, forming a golden sea of fire.
The barrage of ice spikes collided with the sea of fire. The ice spikes were evaporated in an instant.
Kaguya continued to create ice spikes and even expending a large amount of Chakra to create a gigantic iceberg in an attempt to seal Nagasawa inside it.
However, this couldn't stop Nagasawa's golden flames. Just as Kaguya sealed him in ice, the next moment, the massive iceberg disappeared.
"Mother, that guy's flames are too powerful. We can't fight him in this world," Black Zetsu warned Kaguya from Kaguya's sleeve.
He feared that Kaguya's stubbornness to fight Nagasawa in this world. If that really happened, the whole ice in this world might melt, but Nagasawa would be completely unharmed.
"Your ice is too fragile. It can't even cool me down. Why don't you try my flame instead? I guarantee they will make you feel warm," Nagasawa made his move while Black Zetsu was advising Kaguya.
"Reduce everything to ashes!" Nagasawa gripped his sword made of golden flames, compressing all the surrounding golden sea of fire into the sword and pumped a large amount of Senjutsu Chakra into it before swinging it at Kaguya!
The moment Nagasawa swung his sword, the temperature, which had slightly decreased because his golden flame was absorbed into the sword, rapidly increased once again.
In order to prevent Kakashi and the others from being caught in by his own flame, Nagasawa intentionally created three flame shields to protect them.
The moment Nagasawa swung his sword, the temperature in this Ice Dimension was even higher than in the Lava Dimension. Due to the high temperature, all the ice in this dimension began to melt.
As the master of the dimension, Kaguya was clearly aware of this. She stared in disbelief at Nagasawa. This man actually possessed the power to destroy an entire world with a single slash!
The flame that was sealed in the golden sword gushed out all at once, and the overwhelming golden flame engulfed the entire Ice Dimension, causing countless iceberg to melt in an instant.
"If I get hit by this, I'll be severely injured for sure!" Kaguya could immediately tell the horror of Nagasawa's attack.
Hadn't she consumed Chakra Fruit and attained immortality because of that, this attack would be enough to kill her.
The attack came too fast, and Kaguya felt that even if she used Yomotsu Hirasaka to escape to another dimension now, she might still suffer a fraction of the damage.
Kaguya didn't want to risk injuring himself because Naruto and Sasuke were around. If she got injured, she would be sealed for sure.
In that case, she had no choice but to use that move!
Kaguya also possessed a move that could destroy the whole world!
Kaguya utilized the Chakra from the people that fell victim to Infinite Tsukuyomi, and a black sphere appeared in front of Kaguya.
