C125(1)

"You are really generous. Such a precious thing was given to Kushina so easily."

Tsunade hiccupped and spoke to Kain without any ladylike restraint. If it weren't for her beautiful appearance and proud figure, it would be hard for Kain to connect Tsunade with being a woman.

Then, Tsunade poured herself another glass of wine and continued, her expression slightly solemn after drinking, "Are you interested in Kushina?"

However, Tsunade's solemnity wasn't intimidating to Kain. With a flushed face and slightly blurry eyes, the drunk Tsunade should be considered the number one beauty in the ninja world—at least, as long as she didn't speak.

"Kushina should be very important in Konoha, but she comes to me, an outsider, after being wronged. Tsunade, you really should reflect on that."

Kain didn't answer Tsunade's question directly but instead criticized her: "Although the Extremis virus potion is expensive, I'm not stingy when it comes to friends. The key is that this friend should truly care about me."

"You're talking about me, aren't you?"

Tsunade picked up on the meaning behind Kain's words and, dissatisfied, said to him like a kitten who had been scolded. He wondered why, at thirty, she still had such a great charm.

"I also quarreled with the old man, but they…"

Seeing Tsunade suddenly becoming lonely, Kain couldn't help but shake his head and gently persuaded, "Forget it, Tsunade. Since you feel bothered, then don't get involved in this kind of thing."

"Anyway, there's nothing wrong with Kushina improving her strength. At least it gives her the ability to protect herself."

"Well, actually, I came to you for something else—the potion from last time."

Tsunade changed the subject, a little embarrassed. The palliative potion she researched was quite interesting, and it had a special power, but there were too few samples. 

Recently, she had been busy promoting medical ninjutsu and preparations, so she hadn't come to Kain sooner.

"You came here for this? The potion can be given to you, but when are you going to pay me back the gambling debt? The casinos in other places in the Land of Fire are making profits, but the casino in Konoha doesn't even make a fraction of what others do. What do you think is the reason for that?"

Kain said, taking out a few bottles of medicine and placing them on the table. Tsunade was beginning to waver now. With a little more pressure, she might not side with Sarutobi Hiruzen in the future. 

The group led by Orochimaru could also represent Konoha, and the old rot could be swept into the trash.

"I'll pay it back. When I go to a few nobles for medical treatment, I'll have the money to pay you back."

Tsunade said sheepishly, scratching her hair, before turning her attention to the potions Kain had brought out.

"Healing Potion, Blood Potion, and Beauty Potion. The first two potions do exactly what their names imply, but the last one is a bit more magical. It can make the user more beautiful, or rather, more attractive."

After Tsunade heard the words, a look of disbelief suddenly appeared on her face, and she said, "This is too fake. How could there be such a medicine?"

Kain rolled his eyes and said, "Don't be so ignorant. The farthest place you've been to is probably the Land of Rain. You haven't visited the whole ninja world, let alone the world outside of it."

He still has more powerful veritaserum and love potion; otherwise, he would... Hey, do you want to try it?

After thinking for a while, Kain shook his head. Although the potion has incredible abilities, if a ninja could crack it, he'd be embarrassed and offend an enemy for nothing.

"I don't have much time, and I'm going to the battlefield soon. Let me study these first, and I owe you."

Tsunade was so happy that she was ready to take the potions back to Konoha Hospital to study for a while. But just as she was about to get up, Kain grabbed her by the wrist.

"Wait a minute, write an IOU."

After Kain finished speaking, he directly took out a roll of parchment. He wrote down the time and event, indicating that she would return it within five years. Otherwise, she would pay back the amount of money Kain stipulated. 

Of course, the money amount was not written on it.

Because Tsunade was in a hurry, she didn't pay attention. After Kain finished writing, she pressed a handprint and then rushed to Konoha Hospital in a hurry, showing no signs of drunkenness at all.

And she was the one who wanted to treat guests, but now she was the one fleeing from the order.

"This is the lesson of evading orders, Tsunade. Remember not to sign an unfamiliar contract next time."

Kain shook his head and said, but it was a pity Tsunade couldn't hear him. Then he tapped lightly on the parchment, and a cumbersome rune appeared on it. This was a magical contract. If Tsunade couldn't fulfill it, she might have to pay a big price.

This type of magical contract is quite special, similar to an unbreakable oath. However, it's not that serious—one party can break it as long as they're stronger than the other. 

It was used by wizards to collect servants in the past but was later banned by the Ministry of Magic.

Kushina recently wanted to practice Tailed Beast Bomb and Tailed Beast Mode, so she reduced the number of times she came to Kain. The news that she could enter Nine-Tails Chakra Mode had already reached the ears of Sarutobi Hiruzen and other high-ranking officials.

Upon hearing this, it was a mix of joy and sorrow for them—A Nine-Tails Jinchūriki who couldn't be controlled but had taken control of the power of Nine-Tails.
