Kazuki rarely displayed his Body Flicker Technique. To be precise, he almost never revealed his Body Flicker Technique in front of outsiders.
Compared to Fire Release, Lightning Release, and a series of Uchiha-style methods, Kazuki dedicated more energy to researching the Body Flicker Technique.
Kazuki's talent in the Body Flicker Technique was quite good. After all, his son, Shisui, had the nickname "Shisui of the Body Flicker."
Kagami's Body Flicker Technique was also quite famous. It was a Body Flicker Technique that Kagami had improved based on his own circumstances, under the guidance of the Ninja World's fastest, Senju Tobirama.
Kazuki had already learned and integrated the Body Flicker Technique into his daily combat a year ago.
He rarely showed it outside, but in the combat arena, he had no such reservations. The explosive power brought by the terrifying Body Flicker Technique, combined with Uchiha-style swordsmanship, was all about suddenness.
Under Nawaki's slightly stunned gaze, Kazuki's longsword pierced through his abdomen.
However, Kazuki was quickly dumbfounded. Before he could pull the longsword out of Nawaki's abdomen, Nawaki suddenly exerted force, making the sword pierce further into his abdomen.
Nawaki's arms tightly embraced Kazuki, and at the same time, he was clutching several ignited Explosive Tags in his hands.
Is he that ruthless?
Kazuki was shocked. An ordinary Ninja, if pierced through the abdomen like this, would certainly lose their combat ability.
But Nawaki, relying on the terrifying vitality of the Senju and Uzumaki clan, stubbornly held him back, wanting to engage in a mutually destructive battle.
Fortunately, in this past month, Kazuki had grown considerably. He decisively abandoned his longsword and quickly formed hand signs.
"Although I'll never see my sister again, and I can't become Hokage, even if I die, I'll send you to the Pure Land." Nawaki whispered softly as he leaned close to Kazuki.
???
At this moment, Kazuki really wanted to curse Nawaki for not playing fair.
What deep-seated hatred was this?
I just wanted to kill you once to get a reward. Do you need to fight so desperately?
Boom!
The explosion of the Explosive Tags engulfed both Kazuki and Nawaki.
At the same time, Kazuki's figure turned into mud, and his true body appeared not far away, gasping for breath.
Earth Release: Earth Clone, one of the few Earth Release Ninjutsu that Kazuki used well.
In such a scenario, it was very useful.
Afterward, Kazuki's consciousness returned to his body.
[Ding, congratulations to the Host for defeating Nawaki. You have obtained Nawaki's Senju and Uzumaki mixed-blood physique. Do you wish to merge?]
Merge!
As Kazuki's thoughts moved, he felt as if his body was being torn apart, and a terrifying energy was reshaping his body.
Acquiring Nawaki's physique made Kazuki very happy as even without Asura Chakra, this would provide him with a huge boost.
But this cellular tearing caused him unbearable pain. Just as he was about to faint, a warm sensation surged from his eyes, quickly neutralizing the pain.
His Sharingan activated unknowingly. The single tomoe in his eyes spun rapidly, and soon, the single tomoe in those eyes quickly split, with two tomoe appearing in each eye.
Under the influence of Nawaki's physique, Kazuki's Sharingan upgraded once again, becoming a two-tomoe Sharingan.
Just as Kazuki thought the Sharingan might advance further, upgrading to three tomoe in one go, the tearing sensation on his body subsided, and the rapidly spinning two-tomoe also stopped rotating.
"Hoo hoo hoo!"
The merging process was short yet long, leaving Kazuki looking as if he had just been pulled out of a bathtub.
However, this merger significantly boosted his strength. His Chakra doubled, his physique also improved considerably, and with the two-tomoe Sharingan, Kazuki was confident in facing Kotetsu again and thought he could win.
The combination of Uchiha bloodline with the Senju and Uzumaki bloodlines was not as simple as one plus one equals two.
"The improvement is significant but the process is brutal."
Kazuki covered his eyes. He did not continue to challenge others.
With his current strength, challenging young Asuma should not be difficult, but he needed to summarize the previous battle.
Before the battle, his strength was already superior to Nawaki's, and he successfully killed Nawaki in the end.
But his combat experience was still a bit lacking, unlike Nawaki, who had probably been active on the battlefield for some time and was a seasoned veteran.
If Nawaki wasn't too important, Kazuki wouldn't mind dying together with him. He wanted to know if dying together could bring him rewards.
If that were the case, he could use some extreme methods to defeat opponents in the future, such as strapping Explosive Tags to himself to blow up the opponent.
Next, he needed to pay more attention to this aspect. Before he can activate Susanoo, he will be a glass cannon, and he needs to be cautious when necessary.
Potential is ultimately just potential. Sometimes, a single Explosive Tag is enough to be fatal.
In Ninja combat, it's quite normal for the weak to defeat the strong.
This summary lasted for over an hour. Kazuki then challenged Asuma. This young Asuma, probably around fourteen or fifteen years old, had a similar strength to Nawaki and was quickly dealt with by the upgraded Kazuki.
After the battle, Kazuki also gained Asuma's Wind Release mastery at that stage.
Kazuki hadn't really studied Wind Release before. He usually focused on Fire Release and Lightning Release, which were his innate Chakra natures.
But after merging Asuma's Wind Release mastery, Kazuki's proficiency in Wind Release immediately improved, in no way inferior to his current Fire Release and Lightning Release.
Indeed, he still had to rely on the combat arena to cheat.
Unfortunately, Chiyo was unbeatable right now. If he could obtain Chiyo's poisoning techniques and combat experience, that would be awesome.
...
For the next few days, Kazuki was constantly familiarizing himself with and adapting to his newly surged strength.
"Kazuki, do you know? Something big happened at school today."
That day, just as Kazuki sat down, Kushina mysteriously said to Kazuki.
Not long ago, Kushina managed to move her seat next to Kazuki, which made Kazuki feel helpless.
"What happened?"
Not only Kazuki, but even Minato and others in front turned to look at Kushina.
