Strengthening Karin

"Brother Yun Xi, are we there yet?"

Seeing Yun Xi come to a halt, a look of nervousness appeared on Karin's face.

Clearly, for Karin, the Root Division was still a terrifying place.

"Pika, Pika!"

Pikachu was equally tense, standing behind Yun Xi and preparing for battle.

Although Pikachu had been somewhat resistant to Yun Xi at first, after spending this time together, it had gradually realized that Yun Xi was not the person it had imagined him to be.

He wasn't just someone who used electricity to shock it.

On the contrary, Pikachu understood that Yun Xi's goal was merely to use Lightning Style ninjutsu to rapidly increase its strength.

Therefore, after learning the truth, Pikachu had gradually grown closer to Yun Xi.

"Yes, we've arrived, but we need to wait a moment before going in."

Facing Karin's question, Yun Xi nodded.

He also stopped in his tracks, standing right in front of the Root Division entrance.

He needed to bolster the strength of both Karin and Pikachu.

Although Yun Xi's true strength had already reached Kage-level, he decided to use the remaining Krypton Gold Points from last time to increase Karin's survivability, just in case of any accidents.

"Karin, your body might undergo some changes in a moment, but there's no need to worry."

To ensure Karin could accept the sudden system enhancement and to minimize the need for explanations, Yun Xi decided to communicate with her before the strengthening began.

"Okay, Brother Yun Xi."

Although Karin didn't understand why Yun Xi was suddenly telling her this, she knew that he would never harm her.

"System, open the partner cultivation interface."

Seeing that Karin had no unusual reaction, Yun Xi began to summon the system.

He was preparing to spend Krypton Gold Points to strengthen her!

Looking at the familiar interface, Yun Xi said slowly, "How many Krypton Gold Points for the cells of the First Hokage, Hashirama?"

"Ding! The system has successfully queried for the host. The price for the active cells of the First Hokage, Hashirama, is: 100 Krypton Gold Points."

Following Yun Xi's command, the purchase interface for the item quickly appeared on the screen.

"So cheap?"

Seeing the price of the active cells, Yun Xi was stunned.

He hadn't expected that the active cells he intended to transplant into Karin would only cost one hundred Krypton Gold Points.

Such a discounted price made Yun Xi briefly suspect that something was wrong with his system...

"Ding! The item price is correct, but a service fee of 10,000 Krypton Gold Points is required. If used by someone other than the host, the fee is doubled."

Faced with Yun Xi's question, a prompt appeared on the interface in response...

"That shouldn't be right. Why was the price as high as 200,000 Krypton Gold Points when I checked for the transplant earlier?"

Even though he saw that the system still required a service fee for the transplant, Yun Xi still felt it was cheap.

Previously, in order to further increase his own physical fitness, Yun Xi had checked the price of Hashirama's cells in the Shop.

It had required a full 200,000 Krypton Gold Points!

Since Yun Xi only had a little over 80,000 points on hand at the time, he had no choice but to give up.

He had planned to buy them once he had enough money.

But now, transplanting them into Karin, including the service fee, only cost a little over 20,000 points.

This left Yun Xi somewhat confused...

"Ding! This price is only available to those of the Senju Clan or the Uzumaki Clan; others must pay the original price."

Finally, as Yun Xi remained puzzled, the system explained the reason for the two different prices.

"In other words, the price of system items is determined based on each person's bloodline limit or physical constitution?"

From the system's previous explanation, Yun Xi realized that his system could be used in this way!

"System, are there any items that suit my own body?"

Realizing this new function of the system, Yun Xi asked directly.

After all, Krypton Gold Points were very hard to earn, and every bit saved was a bit gained.

"Yes."

Faced with Yun Xi's question, the system directly listed the items eligible for a discount.

"System! Get lost!"

However, after reading the product descriptions, Yun Xi couldn't help but curse out loud!

This was because Yun Xi discovered that the system had only listed one discounted item.

Although the price was only one Krypton Gold Point, making it extremely cheap.

Yun Xi still couldn't help but lash out...

Because the name of this item was...

One Thousand Years of Death...

That's right, it was the original ninjutsu that Kakashi used on Naruto during the bell-snatching test!

"System, if you don't give me a reasonable explanation today, I will absolutely not let you off!"

After closing the personal shop, a few black lines appeared on Yun Xi's face.

Although Yun Xi might have already realized that there probably weren't many items in the Shop that could be discounted.

But this One Thousand Years of Death was definitely beyond Yun Xi's expectations.

Yun Xi would have preferred the system to just tell him there were no suitable discounted items for him.

He would rather that thing not have appeared in the system Shop at all!

"Ding, since the host does not possess any Kekkei Genkai and does not have high talent for ninjutsu cultivation, the Shop cannot offer discounts to the host according to the rules."

"However, One Thousand Years of Death is an entry-level taijutsu, and under certain circumstances, the host can easily master it, which is why the system is offering it for the price of one Krypton Gold Point."

To appease Yun Xi's anger, the system explained in detail why the price of One Thousand Years of Death was so cheap.

"Forget it, I can't be bothered to argue with you. Transplant the Senju active cells into Karin."

Although he had prepared himself mentally, after hearing the explanation, Yun Xi could only comfort himself in his heart that the system didn't know quality when it saw it.

At the same time, he purchased Hashirama's active cells and transplanted them into Karin.

After all, an item that originally cost 200,000 points only required 22,000 Krypton Gold Points under the system's discount.

Although it was limited to Karin, who possessed the bloodline of the Uzumaki clan, Yun Xi still felt he had made a huge profit!

After all, Karin was a very powerful support ninja, capable of performing various tasks such as reconnaissance, healing, and auxiliary combat.

At critical moments, she could also use Sealing Jutsu to assist Yun Xi.

However, her own strength was too weak; although she possessed extremely strong healing abilities, her physical durability was not high.

If she were attacked first, she might even be severely injured and fall before she could heal her teammates.

After transplanting Hashirama's active cells, Karin's overall self-healing ability would inevitably increase significantly.

Yun Xi would also be able to focus all his attention on the battle.

Without needing to constantly check on Karin's situation.

"Congratulations to the host for successfully purchasing active cells (special edition) for a companion. Consumed 22,000 Krypton Gold Points."

As Yun Xi's Krypton Gold Points vanished, Karin's body immediately began to undergo some changes.

"It itches..."

At this moment, Karin also noticed the abnormality in her body, but fortunately, Yun Xi had warned her beforehand.

So she didn't panic too much.

About a minute later, the system enhancement ended, and a thick aura of life burst forth from Karin's body.

At the same time, Karin's entire appearance underwent a huge change!

Yun Xi: "Holy crap, the little buns got bigger!"

[Author's Note]: Let me clarify, Kakashi's master is Minato Namikaze! This idiot author made a mistake earlier and wrote that Kakashi's master was Jiraiya.

It has been corrected now. I hope the readers will forgive me; I am truly sorry!
