Naruto, this is called Kuuga, not White Zetsu

"Let me see what task my sister has given me..."

Shizune suddenly paused when she heard Seto Chihiro's tone, and thought to herself that there was clearly no information about Uchiha Itachi revealed above, so could it be that the junior brother had discovered something again?

But just when she thought she might have taken the wrong scroll, Seto Chihiro's tone began to return to normal.

"Go to the Land of Rain...Visit Hanzo of the Salamander...Protect Jiraiya and Hatake Kakashi..."

"Investigate the leader of Akatsuki... feel whether Nagato has ill will towards Konoha... try to negotiate..."

Seto Chihiro summarized the important contents of the scroll, his tone gradually becoming dull. His attention was now entirely focused on the system, and he was abnormally excited.

[Xiao (Phase 1): In order to make the other party understand the pain of war, it may not be necessary to use force. Perhaps dialogue can also achieve understanding?

Mission objective: Join Akatsuki

Mission Reward: Akatsuki exclusive matching clothing, 3000 points]

[Scarecrow in the Rye Field (Character Mission, Stage 1): A ninja who cannot complete a mission is a waste, but a ninja who doesn't even care about his companions is even worse than waste... I will inherit your will and protect my companions until my death, Obito!

Mission objective: Help Kakashi find the real culprit of the Nine-Tails Night.

Mission Reward: Ice Escape. White Whale]

[Eye of the Moon (Advanced Mission): Someone is very interested in your Wood Release Technique. Perhaps you can learn some secrets of the ninja world from it.

Mission Objective: Understand the entire plan of the Moon Eye

Mission Reward: Yin Yang Escape]

Seto Chihiro's eyes widened involuntarily, but luckily he was lowering his head now, otherwise it would have aroused Shizune's curiosity.

Yin and Yang Escape!

Even after Konoha collected the secret techniques of each family, only the Nara clan had a clear Yin-Tun ninjutsu. Most of the Yin-Yang secret techniques of other families were just rough applications of the Yin-Yang chakras.

There are not many records about Yin-Yang Escape from the Thousand Hands Clan.

And now...

This escape technique, which only those with the Rinnegan and Six Paths level could access, actually appeared in the system's rewards. It was also guaranteed to teach you until you master it, so there was no need to worry about not being able to learn it.

but...

Seto Chihiro had some doubts in her heart, is this reward authentic?

This is not to say that he does not believe in the system. After the system gave him the Aguru Belt, he was a firm believer in the theory of the different world system.

But the rewards of the system this time are indeed a bit strange. One is Kakashi's Ice Release, and the other is Yin-Yang Release. It seems that the gains and efforts are completely disproportionate.

It is no exaggeration to say that Kakashi can use ice escape? Is a plan worth Yin Yang escape?

After adjusting her breathing, Seto Chihiro suppressed her inner excitement and looked up at Shizune calmly.

"By the way, are there only three of us on this mission, Jiraiya, Kakashi, and me?"

"what?"

Jingyin was thinking, whether the junior brother was so smart, he might have figured out the clues from somewhere, but when he was suddenly asked the question, he was stunned for a moment, then nodded quickly.

"Yes, there are only three of you on this mission."

Seto Chihiro rubbed her chin with her palm, feeling a little strange. This task did not appear earlier or later, but appeared three months later. Moreover, there was no specific time for carrying out the task on this scroll.

He is not very qualified as an Anbu. Although he is given special treatment by Tsunade every day, he is still very clear about some task procedures.

Danzo has been dead for almost three months. How could the work of finding the truth only begin now?

Seto Chihiro was a little distressed. This was the disadvantage of not having White Zetsu around. She had to obtain all the information on her own.

Fortunately, his senior sister is the Hokage's secretary. If there are some questions that he cannot ask the Hokage, he can go directly to his senior sister.

"Senior Sister, what does the Rain Village look like?"

"I haven't been to the Rain Village either, but I heard it rains all year round."

Seto Chihiro's eyes lit up: "It rains all year round, I really want to see it, but are we leaving now?"

Jingyin found it funny, patted her junior brother's shoulder, and moved closer to him, pretending to be sad.

"Do you really want to leave Senior Sister?"

Seto Chihiro was startled and shook her head: "How is it possible? I just think that this mission has no departure time. Senior Sister is so kind, how could I possibly want to leave her?"

"You'll say things I like to hear."

Shizune smiled, rubbed her brows and said, "Because Kakashi practiced a ninjutsu that put a lot of strain on the body, he needs to rest for a few days before he can set off."

Chapter 3 Uchiha Izumi's Changes

Kakashi practiced ninjutsu hard for the mission, and even let Seto Chihiro herself participate in the mission in the Rain Country. In addition to the system task that has just been triggered, if he still can't guess that Kakashi has now mastered Kamui, then his life in the Anbu for the past few months may have been in vain.

Every day, you can see an earth clone with less than 1/20 of Kakashi's chakra sitting in the Anbu office handling official business. His humorous appearance cannot hide his irritable heart.

Moreover, given Kakashi's current age and workload, it is impossible for him to develop new ninjutsu, let alone research the changes in the lightning attribute of the Rasengan.

Being able to spend three months to rapidly enhance one's own strength, it can be said that there is no other possibility except divine power.

However, Seto Chihiro did not think about this matter for long. After all, these were just guesses. So he put the scroll back into the ninja tool bag and followed Shizune.

Leaving the Death Forest, a familiar figure walked over from a distance. The pair of eyes under the mask were as lifeless as dead water, and a heavy aura surrounded the person.

Seto Chihiro subconsciously froze where he was. After two or three seconds, he realized that Black Zetsu had already left Konoha, and there was no need to pretend like this anymore.

"Let's go. What are you still doing here?"

"Nothing, I just thought of something."

Shizune looked at Uchiha Izumi who was walking by her side, and only said slowly after he was far away: "Let's go, go back and have a good rest. I can't go with you this time."

"Ah."

Time passes quietly and the summer nights are irritating.

Mosquitoes were buzzing around, and even if the windows were closed, you couldn't tell from which corner they would appear in the room.

Seto Chihiro also got bitten one or two times. His physical condition would recover in no time, but losing some blood for no reason would still make people feel uncomfortable.

Unfortunately, not only did he not have time to find trouble with mosquitoes, he also had to sit there obediently.

"Chihiro, this is your first time leaving Konoha for a mission. I am still very confident in your strength, but you have practiced Wood Release too many times in Konoha. It is very likely that spies from other villages have known about it. Be careful of ninjas from other ninja villages when you are outside..."

"Konoha's new barrier has indeed isolated some spies from the outside, but there is no guarantee that some spies may have not left Konoha before."

"Kakashi is recovering right now. I will find time in the next few nights to explain the mission process to you. I will also tell you some information about the Sage's Eyes - the Samsara Eyes. Although most of it comes from myths and legends, we may be able to deduce from them what abilities these eyes have."

Seto Chihiro raised her head and secretly glanced at Tsunade who was sitting on the chair. She usually came back around 10 o'clock in the evening, but today she returned to the Senju clan early.

He really didn't know the exact procedure for the mission, but with Kakashi and Jiraiya, he didn't need to think about it at all.

However, he still remembered a lot about what kind of abilities the Rinnegan had.

"That's all for tonight."

Tsunade also heard about the Forest of Death from Shizune, and the boy was exhausted today.

She left Seto Chihiro's room, and as soon as she came out, she saw Shizune standing at the door with a midnight snack in her hand.

"Lady Tsunade, are you planning to take a break?"

"This kid is already a little absent-minded."

Tsunade picked up a bunch of meatballs, evaluated them and then said, "They taste good. I'll leave the rest of the work for today to Jiraiya, and I plan to take a good rest."

Shizune nodded, "Then I'll give Lady Tsunade a massage later."

In the next few days, Tsunade would leave the Hokage Building early every day like she did today and return to the Senju clan. She would hand over all the information about the Sage's Eye that was gradually analyzed and sorted out by the Anbu to Seto Chihiro, and would also record the ninjutsu that Jiraiya taught Nagato and Konan on the scroll in his hand.

At the same time, the news that Seto Chihiro was going out on a mission also reached the ears of Uchiha Mikoto and Uchiha Izumi.

During these three months, with the help of Tsunade, Uchiha Mikoto successfully took back her own clan land and built a laboratory underground.

Of course, Uchiha's bloodline limit is already the pinnacle of the ninja world, so this laboratory is not aimed at the bloodline limit, but the chakra that every ninja cannot do without.

Most of the ninja clans in Konoha have very different research directions regarding chakra, and there is absolutely no general and reliable statement.

Although they all have Yang-attribute chakra, the Akimichi clan can develop Yang-attribute chakra properties to strengthen their bodies, but the Aburame and Inuzuka clans can develop into raising parasitic insects and training ninja dogs.

If you cannot summarize some advantages from these secret techniques and use them directly, you won't achieve much.

As various family documents were burned, Uchiha Mikoto stayed at home to train her clan members. It can be said that she has plenty of time and is the perfect choice for this job.

After hearing Seto Chihiro's suggestion, the other party used summoning techniques to ask the Ninja Cat Clan to help purchase a batch of experimental equipment in the Ninja World.

Considering that Uchiha Mikoto was not a serious scientific researcher, Seto Chihiro used the 'Bubble Helmet' to record all the experiments in her mind on paper, and also gave the general experimental hypotheses to Uchiha Mikoto, who then conducted the experiments step by step.

Building a laboratory does not actually bring much improvement to Seto Chihiro, but for Kurama Yakumo and the Uchiha clan, it is an excellent way to become stronger.

Both ninja clans have extremely high requirements for the changes in the nature of Yin-attribute chakra.

Just building a laboratory or something, naturally there is no way to escape Black Zetsu's sight, but many families in Konoha have laboratories similar to this one for chakra research. As long as other people don't find out that the initiator of the establishment of this laboratory is Seto Chihiro, there will be no other major problems.

The night before the mission.

Seto Chihiro's clone appeared in the Uchiha clan's underground laboratory.

The entire laboratory is divided into four sections. There is a heavy computer on the east side. On the tables on the west and south sides, the liquids in various test tubes and vessels are sparkling under the lights. The north side is very empty, and the ground is pitch black. It is a place used for experiments. In the center of the four sections are two pitch-black passages, one leading to Uchiha Mikoto's room, and the other leading to Uchiha Izumi's room.

Under the bright light, Uchiha Mikoto was wearing a snow-white chemical protective suit, and the subtitles on the computer monitor were shining on her mask.

Although there are already cameras in the ninja world, every time Seto Chihiro sees this scene, he always feels like he has returned to the production line in his previous life.

"You're here, Chihiro."

Uchiha Mikoto, who was recording experimental data, sensed a figure appearing in her peripheral vision and greeted him without even raising her head.

"Good evening, Mikoto-san."

The 'clone' looked around, walked to the lab table, skillfully picked up the chakra test paper, and began the experiment that was not completed last night.

The learning process of Flying Thunder God is easier than imagined. It can also be said that with the "Bubble Helmet", the efficiency of doing a thing is greatly increased. As long as Black Zetsu does not appear on the ground, he will not be discovered wearing the helmet and learning Flying Thunder God.

And ever since he learned Flying Thunder God, he came over every night in the few days after Black Zetsu left. Sometimes he helped Uchiha Mikoto, and sometimes he studied Ice Release by himself.

But I was exhausted after a long day, and I had a mission tomorrow, so I went to bed early.

"Are you alone tonight too? Isn't Sister Quan here?"

"Uchiha Mihui's written test results were not good. Izumi has a day off tomorrow and I am tutoring Mihui tonight."

"Meihui? I remember she was very serious in class, wasn't she?"

"Ah... I don't know either. She's obviously a very smart child. Her talent in Fire Style is terrifying. But she got such a simple question wrong. It's really hard to understand. Maybe, just like what you said, it was the awakening of the Sharingan that caused her personality to change."

While the two were talking, there was a whistling sound from the exit above their heads. In less than two seconds, a figure fell directly from the top of the passage, splashing some dust.

"Mikoto-san, huh? Chihiro, why are you here too?"

Uchiha Izumi turned his head slightly, looking confused.

She was curious about Seto Chihiro's appearance, as the latter would have to go out on a very difficult mission tomorrow.

"The main body is a little tired today and is sleeping, so let me come over and complete this experiment."

Seeing that the 'clone' didn't even raise his head, staring intently at the chakra test paper in his hand, Uchiha Izumi walked over, becoming more and more curious about the other party's experimental results.

"Are you still researching Ice Escape?"

"Yes."

Uchiha Izumi lay on the table, not caring about his image at all. His delicate face looked a little tired, and his pair of brown eyes twinkled.

Although she is only 13 years old, she exudes a youthful aura, which is completely inconsistent with her cold image in the past few days.

"Can Ice Release be performed by fusing the two chakras of wind and water? Obviously, most wind-attribute ninjutsu cannot control the temperature."

"Uh...there shouldn't be any problem, right?"

The clone hesitated, but if he couldn't synthesize ice escape in this world, then there would be no ninja who could synthesize ice escape. He thought about it and continued:

"The reason why the wind in nature has cold and warm temperatures is because of the different air pressures. Although the wind created by chakra is called wind, it is just the wind-attribute chakra that is ground into a thin layer, which can form cutting and sharp edges. Changing the wind-attribute chakra in the direction of cold and warm, expanding and contracting, should be able to affect the temperature of the water, and directly synthesize ice escape when releasing water escape."
