Even Kazuki had to admit that Lightning Chakra was very troublesome, and this Bee, in particular, was probably no weaker than the future Fourth Raikage.

His speed might not be as good as the Fourth Raikage's, but in terms of defense, he was stronger than the Fourth Raikage.

Kazuki knew how to deal with this so-called strongest shield.

His Sharingan's observation ability was not inferior to Naruto's when he used Sage Mode.

It was just that his strength was not comparable to Naruto's at that time.

He could try to replicate Naruto's fighting style against the Third Raikage, but it wasn't a sure thing.

Chidori was useless, and as for Rasengan, it hadn't been "developed" by him yet.

It wasn't that Kazuki didn't know how to create Rasengan. In reality, the "development" of Rasengan was much simpler than Chidori's.

The training process of Rasengan appeared in the anime. With Kazuki's current understanding of ninjutsu, it wouldn't be difficult to develop Rasengan, but it didn't have a proper origin.

Minato developed Rasengan based on the Tailed Beast Bomb, but Kazuki had never seen a Tailed Beast Bomb, so how could he develop Rasengan?

Could it be that the Uchiha ancestors had information about the Tailed Beast Bomb?

Before, Kazuki was too busy researching other Ninjutsu, how could he have time to research Rasengan?

After returning this time, he would need to research Rasengan.

Just as Kazuki was hesitating whether to help Tsunade and the others deal with Bee or to fight the Kumo ninjas with Root, he sensed a familiar Chakra rapidly approaching them.

This Chakra made him pause. As he pondered, a golden, petite figure had already appeared not far from them.

Is this Nine-Tails Chakra Mode?

Kazuki's heart was in a daze as he looked at the golden Kushina.

Then, his expression changed again. This was not Kushina, but Mito.

Good heavens, Mito had possessed Kushina!

Kushina's physical condition was not good, but there was a way to temporarily enhance her strength. Nine-Tails Chakra Mode allowed her to possess strength surpassing Tsunade's.

Kushina's combat experience was insufficient, but now that the old grandmother had possessed her, how could that experience be compared to that of an ordinary ninja?

Mito had also fought her way through the Sengoku era, even clashing with Hashirama.

During the First Great Ninja War, she played a huge role, and it could even be said that she suppressed many strong individuals.

Using Kushina's body, even if she couldn't match Bee, she probably wasn't far off.

Mito arrived at the scene and first looked at Kazuki, finding that he was displaying ease.

This little fellow's strength had already reached Jonin level, and he was probably not far from an ordinary elite Jonin.

Letting him experience such a battle had its benefits.

Then, she turned her gaze to Tsunade, who was being suppressed, and a hint of disappointment flashed in her eyes.

Clearly, at this moment, Tsunade was fighting for her life, but with the massive consumption of Chakra, her condition was slowly declining. If it went on for too long, she might be in danger.

Mito didn't know much about Bee, but she was very familiar with Lightning Release Chakra Mode.

She had beaten the Second Raikage herself back then.

Fighting a Raikage in Lightning Release Chakra Mode wasn't that difficult.

Once Nine-Tails Chakra Mode was activated, she would slowly find the opponent's weak points during the battle, then slap them, use Sealing Jutsu, and the opponent wouldn't even be able to use Lightning Release Chakra Mode.

As long as they couldn't use Lightning Release Chakra Mode, the opponent would no longer be a threat.

Just like that, the opponent could be easily dealt with.

As Hashirama's wife and a super genius of the Uzumaki clan, even without the Nine-Tails, Mito's strength was not inferior to Tobirama's, and with the Nine-Tails, her strength had already surpassed the Five Kage level.

In the public eye, Mito was currently the strongest person in the Ninja World.

She naturally had the right to say such words.

Unfortunately, Tsunade usually hadn't studied Sealing Jutsu properly. Otherwise, a Taijutsu ninja like Bee would be very easy to deal with.

"Kushina" transformed into a golden light and arrived in front of Tsunade, clasping her arms together to block the attack for Tsunade.

Bee's massive fist landed on "Kushina", causing both sides to retreat several steps, but this time, Bee's retreat steps were no less than "Kushina".

"Kushina!"

Tsunade saw "Kushina" arrive and immediately became anxious.

"This is not a battle you can participate in."

"Tsunade, watch closely."

However, "Kushina" had no intention of leaving and instead transformed into a golden light, engaging Bee in battle.

Bee and "Kushina" fought, and the more they fought, the more shocked Bee became.

What was going on with this little girl?

Her physical condition was clearly not as good as his, yet she was making him tremble with fear.

What exactly was going on in Konoha? Where did all these geniuses come from?

"Grandma?"

Tsunade looked blankly at Kushina fighting Bee, muttering.

She was very sure that this was definitely not Kushina, but her grandmother, Mito.

"Tsunade, what's going on?"

Sakumo, with his left arm dangling, quickly retreated to Tsunade's side and asked anxiously.

In the previous battle, he had also fought desperately.

If nothing unexpected happened, he would probably have to lie down for a few months after returning to Konoha.

But how could that girl named Kushina be so powerful?

"This isn't Kushina, it's my grandma acting as a substitute." Tsunade smiled.

It was true that she couldn't defeat Bee, but she had her grandma.

Grandma was indeed grandma. Even when using Kushina's body, she still subtly held the upper hand against Bee.

"Mito-sama?"

Sakumo was startled by the words. He thought of how Mito had turned the tide in a previous battle.

Apparently, she also emitted such golden light at that time.

Then he also let out a sigh of relief. Since Mito had arrived, he no longer needed to worry, and an unprecedented sense of exhaustion permeated his entire body.

"Mm, Grandma left a contingency plan on Kushina's body, and I guess this is it." Tsunade smiled, sat down casually, and began to heal herself.

After the Mitotic Regeneration ended, she felt an unprecedented throbbing pain in her chakra pathways. It would be better not to use it if possible in the future.
