Naruto: The Strongest Sage.

Aoba had long expected that Orochimaru would have some tricks on Sasuke. Naturally, he couldn't have been unprepared, so he directly prepared a scroll of the evil seal for Sasuke to prevent him from losing his fighting ability during the exam.

On the other side, Karin had already hung three Kusagakure ninjas on a tree and slowly bled them out. This action was seen by the Konoha high-ranking officials who were watching the battle. Suddenly, it seemed that this cheerful little girl seemed to have a dark heart.

Moreover, the Third Generation knew very well at this time that Aoba was the one who rescued Karin and her daughter from the Kusagakure ninja, not a bandit.

But how can I put it? At this time, let alone Karin is already a member of Team 7. Even for Aoba's sake, this matter cannot be admitted.

Fortunately, it is the Kusanagi's foreign policy and there is absolutely no way they will come to the door to hold him accountable. Therefore, it is best to let this matter go.

The second group exam was extremely bloody. Karin's revenge seemed to be the beginning. The subsequent fighting became even more brutal.

When Team 7 arrived at the destination, four teams were already waiting there.

They are Chino of Kurenai Yuhi, Hinata and Kiba. Apart from anything else, this exam is actually a highlight moment for Chino.

Because he used bugs to make traps, he killed a group of waterfall ninjas who were ambushing them at the beginning, and successfully collected the scrolls.

Afterwards, with the assistance of Hinata and Kiba, two perception ninjas, they avoided all possible dangers and arrived at the destination in the evening of the first day.

At that time, Gaara's group hadn't arrived yet.

At this point, we can see the position of the Byakugan, a bloodline limit, in actual combat. Unlike the eye technique of the Sharingan that directly increases combat ability, the Byakugan is mostly used as an auxiliary in actual combat. However, in team battles, its effect is still higher than that of the Sharingan.

In addition to the two groups of Hinata and Gaara, the other two groups are the group of Ningji, Tenten, and Rock Lee, and the group of Sound Ninjas.

This situation is actually very interesting. Because Orochimaru's original plan was to let the Sound Ninja stimulate Sasuke. As a result, Uchiha Sasuke directly used the Sealing Evil Seal to control the effect of the Curse Seal.

This made Orochimaru wary of Aoba again. He didn't believe Sasuke would prepare this thing by himself. The seal of evil is not an ordinary sealing technique. The one engraved on the scroll requires extremely high attainments in sealing techniques.

It is impossible for Sasuke to do this, unless Kamikawa Aoba prepared him in advance.

"Interesting." Orochimaru was not surprised that Aoba knew his plan. Because Aoba was always able to get all kinds of information, Orochimaru was already somewhat used to it.

What he was really interested in was that although Aoba knew that he might attack Sasuke, the other party did not stop him, but only asked him to take a scroll as insurance. Was he so confident in Sasuke, or in himself?

Orochimaru knew how powerful the curse seal was. This thing was born out of an immature fairy technique. It was not an exaggeration to say that it was the culmination of his research over the years. He absolutely did not believe that Aoba could easily break it.

Aoba really didn't care much about Orochimaru's actions, because he was currently testing the second version of the chakra battery to its limits.

"Continue to inject chakra."

About a minute later, the sealing technique around the flesh ball completely collapsed, and the flesh itself began to multiply crazily.

Qingye used a fire escape to burn the thing into ashes.

"Okay, let me record it now. After the chakra compression and the combination of sealing techniques, the maximum carrying capacity is about one thirtieth of yours, right?"

"Yes."

"Very good, that's about enough."

Don't think that Yumi's 1/30 of chakra is too little. She is competing against Hashirama's sage body. And when did Hashirama Senju ever lack chakra in his battles?

Qingye even felt that the other party had reached the level of a congenital master in martial arts novels. Chakra was endless and almost endless.

Even if Yumi is not as good as Hashirama Senju, one-thirtieth of her chakra is at least equivalent to more than ten cards. It is enough to deal with most situations.

"Great, now let's move on to step two. Shape this thing."

Qingye couldn't let anyone go out with a meatball. Apart from anything else, the style of the painting was a bit strange. Secondly, the meatball was not very convenient.

This thing is about the size of a child's fist. It needs to be worn close to the body.

It's not too big, but it wouldn't be comfortable if worn next to the skin. And this size is already a bit conspicuous.

"Do you have any other ideas?"

"There are many, but they all have many problems. The best one is that we can make it into a piece of clothing that people can wear directly. In this way, there will be no such obvious problem."

"But that would be too large an area, and it would be easy to be attacked in battle. And once it is damaged, the battery might go out of control, right?"

"That's right. This risk is a bit too great. We need to improve the sealing technique that binds the battery. Make it more stable, or at least not explode at the slightest touch."

In fact, the flesh and blood did not really explode. Instead, it multiplied rapidly and might even swallow up the user.

This risk is indeed a bit high. It is almost impossible to use it in actual combat outside the laboratory. Therefore, it still needs to be improved in the next version.

But Qingye was not depressed. Because he now realized the power of the sealing technique in this world. No wonder the major ninja villages had such a big opinion on the Uzumaki clan.

The more you study the sealing technique, the more you will understand the incredible power of this technique.

Before the five major ninja villages had mastered the five elements of ninjutsu, the Uzumaki clan had already begun to think about creating a god of death. This progress was indeed a bit beyond the scope.

However, the fact that they attracted the joint attack of multiple ninja villages at the same time was actually strange. Aoba had realized this before, but he did not choose to investigate the matter in depth.

One reason was that he didn't have time. Another reason was that he had a vague feeling that there might be some dangerous information hidden behind it. So, he didn't choose to touch it for the time being.

"Chakra battery, sealing technique enhancement and improvement, first experiment."

"…Experiment failed. Record the data and prepare for the second one."

Aoba's experiment was still going on, but he was startled by a chirping sound from above. It was Naruto's loud voice.

"Sakura, why are you here?"

"It's Aoba-sensei. She asked me to study here."

"Ah, I forgot. You are also a disciple of Mr. Aoba. Let's go and have barbecue together?"

"Ah, but..."

"No buts, we can just put it on Mr. Aoba's account. That guy promised to treat us to barbecue, but now we can't even find him. I'm going to bankrupt him this time!!!"

Listening to the little brats running away with their chattering, Qingye shook his head and continued his experiment.
