Challenge, Six-Tails and Tsunade's Integration

Senju Hashirama felt a pang of disappointment. He was somewhat lost in thought. His wife, brother, and grandchildren all sided with Uchiha Osamu. Could it be that he was wrong?

No! I am not wrong, my thinking is correct. War only brings hatred, and hatred can only breed war. The only right way is for villages to understand each other.

After a brief moment of confusion, Senju Hashirama reaffirmed his resolve. He looked at Uchiha Kō and said calmly, "If you want to prove that your ideal surpasses mine, then defeat me!"

Senju Hashirama challenged Uchiha Kō, betting their ideals and their beliefs on each other, determined to prove he was right!

"Heh, Lord Hashirama, aren't you also using force to coerce me into submission? What's the difference between us? Oh, right, there is a difference. I use force against external forces, while you use force against internal forces." Uchiha Kō's words made Uchiha look dazed. Recalling the past, it seemed to be true.

It was only because Izuna was dead that he couldn't defeat Izuna in a fight or argue with him, leaving him no one to take his place. Now, his eldest grandson has avenged him?

Senju Hashirama didn't reply. He no longer cared whether he was in the right or wrong. All he wanted now was to teach Uchiha Kō a lesson and make him understand that force was not the only way to solve problems!

Uchiha frowned. "Have you no shame?" he was about to speak when Uchiha Kō spoke up before him, "I accept this battle. The time is set for two days from now."

Senju Hashirama silent, nodded, gave Uchiha Kō a deep look, and turned to leave. This was the first time he had experienced such loneliness, with no one following him.

Uchiha Kō smiled and said, "Thank you all for today!" After saying that Uchiha Kō cupped his hands in thanks to his supporters.

Everyone waved their hands, indicating that they would support him regardless of victory or defeat! This warmed Uchiha Kō's heart; there were still more normal people than people like Senju Hashirama.

After everyone left, only Tsunade and Uchiha Kō remained at the door. Tsunade looked at Uchiha Kō with a worried expression and murmured, "Owl-kun, my grandfather's strength is unfathomable. Compared to him, I'm like a small river compared to the ocean. You..."

Uchiha Kō pinched Tsunade's cheek and smiled, "Don't worry, I'm fine."

"Hmm~ I didn't expect Grandpa to be such a stubborn person or an idealist. Maybe it's because of his unparalleled power that he felt war was nothing special and grew tired of it." Tsunade's face was being pinched, but she didn't struggle.

"Perhaps, Tsunade. I won't be coming for the next couple of days to prepare for this duel. You should also familiarize yourself with the Saiken's abilities as soon as possible. From now on, you'll be a Jinchūriki, with unlimited Chakra to use!" With that, Uchiha Kō smiled slightly.

Tsunade nodded, and then Uchiha Kō left. Tsunade couldn't help but blush as she watched Uchiha Kō's tall and straight back.

Her man was indeed handsome! Even the way he walked had a certain grace. Only after Tsunade could no longer see Uchiha Kō's back did she return to her room, feeling somewhat disappointed.

The voice of the Saiken suddenly rang out, "Tsunade, your boyfriend was just about to fight Senju Hashirama, right? Holy crap, he's really brave!"

"Sigh, I don't really want them to fight. It wouldn't look good if either of them lost, but Grandpa..." Tsunade stopped there, realizing it wasn't good to talk about her elders behind their backs.

"Tsunade... don't worry, these two are both Kage Level powerhouses, and they're from the same village, so they definitely won't go for the kill," Saiken reassured her, though it was also a little curious.

Whether the strongest of the previous era, Senju Hashirama, or the strongest of this era, Uchiha Kō, is more powerful, we'll surely find out in two days. It'll be a feast for the eyes!

Tsunade sighed and continued communicating with Saiken, trying to understand each other's hobbies, habits, and strength.

Saiken said it excels at Ninjutsu attacks, can grant Jinchūriki to spray acid and Bubble Techniques, and also has regenerative abilities and Chakra acquisition speed.

Tsunade lit up. She used to only know close-combat Taijutsu, but now she could also use Ninjutsu!

So Tsunade decided to give it a try and asked Saiken. Saiken nodded, since the two of them were now one and shared both honor and disgrace, so it was natural for them to give it a shot!

Then Tsunade first tested the strong acid spray in the training ground. She aimed her right hand at the wooden dummy, then circulated her Chakra, and the white strong acid liquid sprayed out. The moment it touched the Wood Golem, it corroded it and then burst into flames.

This power! Tsunade lit up. She had only tested it slightly and hadn't used much force, yet it had such an effect. If she used her full strength, wouldn't the area-of-effect damage be enormous?

"Saiken, you're amazing! You're incredible!" Tsunade exclaimed without reservation, completely bewildered by Saiken. "Ahem, it's nothing, it's just the beginning."

Although Saiken said that, the corners of his mouth unconsciously turned up. This was the first time he had been praised by Jinchūriki. Utakata, that guy, only knew how to borrow power and didn't even say thank you. Humph!

The bond between Saiken and Tsunade quickly intensified, and then Tsunade had a flash of inspiration. "Saiken, now that we're one entity, right? Does that mean I'm immune to strong acid liquid?"

"That's right, with me inside your body, you're immune to acidic and alkaline damage. But why are you asking this?" the Saiken, somewhat puzzled.

Tsunade smiled and said, "I've got a brilliant idea! I'll enchant my fists! Saiken, let the strong acid liquid cover my fists and feet, and automatically recharge it."

"Next, watch closely!" Tsunade moved in Body Flicker Technique and delivered a Heavenly Foot of Pain, breaking the Wood Golem. Even after the break, the Wood Golem dummy was still making a hissing sound!

Even the Saiken was stunned. Could strong acid liquid be used like this? Enchantment! So this is what enchantment is—massive physical damage plus Ninjutsu damage. Its master is quite something.

"Hehe, it's done!" Looking at the Wood Golem emitting white smoke, she felt a surge of joy. If it were a human, not only would they suffer physical damage from violence, but after being knocked away, they would also suffer secondary damage from the corrosion of their wounds!

"Tsunade, you're a true fighting genius!" Saiken didn't hold back his praise. In fact, only Tsunade could pull off this kind of fighting style because of her exceptionally high physical attributes. With her physical damage maximized and her Ninjutsu damage complemented by it, she truly deserves the title of the strongest female ninja!

Tsunade chuckled, clearly not one to back down from praise. Then, under Saiken's guidance, she began training in Bubble Techniques: the explosion and corrosion techniques for small bubbles, and the flight technique for large bubbles.

This made Tsunade extremely happy, and Saiken couldn't help but smile as he watched Tsunade's lively, cheerful, and energetic appearance. This little girl was much better than that Tenten who had a persecution complex and a cold, icy face!
