Understanding the intentions of their originals, Minato Namikaze immediately activated the Nine-Tails Chakra Mode upon his appearance.
Swish~!! A brilliant golden aura enveloped Minato, covering him entirely in a shimmering golden hue, even his cloak turned translucent gold.
Simultaneously, a heavy aura emanated from Minato, spreading outward in all directions.
Noticing this, Minato frowned slightly and suppressed his aura, retracting the Nine-Tails Chakra Mode, causing the pressure to dissipate.
Similarly, Kakashi Hatake did the same. Sporting his new look with a black and red cloud-patterned robe, his mask was not the previous yellow-black striped one nor the single-eye swirl mask worn by Obito, but the three-toothed Sharingan mask from the Fourth Great Ninja War.
It was the one with both eyes visible, able to cover the entire head, leaving only the back exposed.
After all, the Sharingan wasn't like the Byakugan; a mask would obstruct vision, affecting combat effectiveness.
At this moment, the Eternal Mangekyou Sharingan in Kakashi's two eyes slowly revolved. Upon closer inspection, besides the original scythes, there were three additional smaller scythes.
Evidently, this was the appearance of the Eternal Mangekyou Sharingan after the fusion of two pairs of the same source. Facing this pair of Eternal Mangekyou Sharingan, Wu Chen's original body felt the pressure as though it were a rising tide, dense and heavy.
Not only that, but the eyes also seemed to possess a sort of charm, irresistibly drawing others to meet their gaze.
At this moment, as long as Kakashi activated his genjutsu, his hit rate would be one hundred percent.
As for Deidara, his appearance was unique, just like the picture shown at the time of his extraction.
With his blonde ponytail and handsome appearance, the mouths on his hands were somewhat eerie.
Seeing the three shadow clones each assuming the role of the three individuals, Wu Chen's original body once again assumed the role of Pain, the Deva Path.
In an instant, with Minato Namikaze, Kakashi Hatake, Deidara, and Pain's Deva Path along with Nagato Uzumaki's Deva Path, ten people in total crowded into the already small bedroom.
Suddenly, the bedroom became even smaller and more crowded.
Fortunately, at this moment, Kakashi activated his ability, summoning a whirlpool and sucking everyone in.
In order to test the strength of the upgraded Minato, Kakashi, as well as the newly summoned Deidara and Pain's Deva Path, there was no suitable training ground other than Kakashi's Kamui space.
This space had been used by Wu Chen like this before, so it naturally didn't change now.
However, as soon as they entered the Kamui space, Wu Chen, playing the role of the Deva Path, found that the Kamui space seemed a bit different.
Originally, the Kamui space consisted of islands floating in the void, but now those islands were all connected, forming a whole.
"Is it because all the Sharingan have gathered and formed the Eternal Mangekyou?" Wu Chen looked at Kakashi, who nodded.
"In that case, let's spread out a bit to avoid affecting each other," Wu Chen said.
So, except for Nagato, the other nine people dispersed around and began the ninjutsu bombardment test.
Minato Namikaze directly activated the Nine-Tails Chakra Mode and, under this mode, unleashed his ultimate move, the Spiralling Flash Super Round Dance Howl Four.
He first scattered the Tri-Pronged Kunai like a shower of flowers, then used the Shadow Clone Technique to create shadow clones that continuously flashed and attacked between the Tri-Pronged Kunai.
Meanwhile, Minato, the original, gathered a Giant Rasengan, and finally, together with the shadow clone Minato, used the Giant Rasengan to attack the airborne enemy!
The advantage of this move was its speed and sufficient power; the enemy didn't even have time to react and was knocked out by Minato's combo, then killed directly.
The downside, however, was the need for very high reaction speed.
Only after activating the Nine-Tails Chakra Mode could Minato achieve this. Otherwise, even he himself couldn't perform this move in his normal state.
It could be said that after activating the Nine-Tails Chakra Mode, Minato's reaction speed had reached the limit of human capabilities.
What's even more remarkable was that under this mode, his body could keep up with his reaction speed.
Compared to Minato's conspicuous actions, Kakashi Hatake's side was much simpler.
None of his other abilities changed much; the only change was the completion of the Susanoo and the upgrade of his Sharingan to the Eternal Mangekyou.
So, Kakashi first experimented with long-distance Susanoo attacks.
These were attacks directly caused by distorting space.
How powerful was space? In Avengers: Infinity War, one of Thanos' powerful subordinates had his hand cut off by a teleportation portal created by Doctor Strange, which directly severed it.
This example illustrated the power of space.
Whoosh~ A whirlpool appeared in the distance, directly tearing apart the boundaries of the Kamui space!
After the Susanoo experiment, Kakashi's eyes narrowed, and then he activated the Susano'o.
Whoosh~ A greenish half-skeletal figure appeared, enveloping Kakashi, and then the skeleton fleshed out, gradually turning into a stern warrior clad in clothes.
At this point, there was no further action.
Kakashi had just activated the Susano'o with the Eternal Mangekyou Sharingan, and he wasn't very proficient yet. It was expected that he could fully activate the Perfect Susanoo with a height of a hundred meters in the future.
