Time flies, seven days go by in a flash.

Ryuuji didn't wait for the red.

When she was passing through the border of Kawanokuni, she met Hakura, who was on a mission, and she pulled her to help.

A group of unknown origins have also set their sights on the Greel's Stone, pestering them on the other side of the Rift.

Although the other party also uses chakra, they have a power system that is clearly different from that of ninjas, and their appearance and characteristics do not match those of people from various countries in the ninja world.

It is suspected that he is from the opposite continent.

They seem to have information about the Stone of Grell and are extremely familiar with the Great Rift Valley.

The team led by Ye Cang was ambushed when they first arrived in the Great Rift Valley, and they did not understand the enemy's power system, so they suffered a big loss in the first battle, and three of the ten squads were killed.

This can be said to be a very serious loss.

Ryuuji didn't pay much attention to this.

Because, according to the news that came back from Hong, the strongest enemy is only the level of elite ninja.

The reason why Ye Cang was unfavorable in the first battle was completely because he was ambushed and did not understand the enemy's ability, and the next time they met, it was difficult to say who would win and who would lose.

And now with Red Assist, as long as the enemy is discovered, you can play GG.

He is now more focused on the research at hand.

The Yin Seal was successfully deduced by the Observatory last night.

However, the silver school will not.

The principle of this thing is to seal the chakra that is refined on a daily basis in the seal of the brain through the delicate operation of the chakra.

This requires extremely high chakra control.

Silver doesn't have this level of chakra control, and he can't refine chakra by himself.

Therefore, Ryuuji suspended the development of the follow-up super-speed regeneration and Baihao's technique.

Prepare to wait for the cultivation of the immortal cells to complete and make a new body for Silver before trying.

Now, he devotes himself to the study of crystal necklaces.

It is mainly the study of sealing techniques.

The sealing technique sealed in the necklace has a super inhibiting power on the chakra, which can sever the connection between the person and the chakra.

It's like in the original book, the four generations of Hokage used to block the contract seal between Obito and the Nine-Tails.

But there are some differences.

The seal of the fourth Hokage is to block the connection, and this seal is to completely seal the chakra, making it unusable.

If he can expand and strengthen the research on this seal, then he may be able to develop the tailed beast sealing technique that he has in mind.

Of course, Ryuuji has not forgotten his purpose.

So I didn't stay in the studio all the time to do research, and I would go to the ninja school and hospital every morning.

It's called inspecting the study abroad group.,It's actually looking for a suitable candidate to be replaced by the wooden ninja.。

Several suitable guys have been spotted so far, but further investigation and screening are needed to determine them.

……

Little by little, time passed.

The Third Shinobi War intensified.

Grass Hide, Rock Hide, Cloud Hide vs. Konoha Hide, Rain Hide vs. Iron Country, Sand Hide vs. Rain Hide, and the rest of the small and medium-sized ninja villages saw that the Great Ninja Village was in the war, and they didn't have time to take care of themselves, so they also participated in their own wars.

Except for the fact that the Fog Hidden Village seems to be still in civil strife, the entire ninja world is in the midst of war.

But in this piece of battlefield, the most fierce battle was not the war of the coalition forces against Konoha, but the surprise attack of Yuyin on the Land of Iron.

The Land of Rain is connected to three major powers at once, and it is possible to be invaded by other countries at any time. Hanzo had to end the war against the Iron Country as soon as possible, so he used all his strength to launch a full-scale attack.

The country of iron is not intimidated, and the samurai are dispatched, and the front is tough.

When Sha Yin sent troops to Yuyin, Hanzo fought more urgently and aggressively, wanting to end the war as soon as possible and return to the village.

And the war of the coalition forces against the Konoha side...... The combined forces of Iwakure and Kusakure are still facing off against the Konoha defenders on the border of the country of grass, and there are occasional skirmishes, and they are generally in a state of peace.

And in the country of Tano, Yunyin's battle line against Konoha ...... Although Yunyin Village has been launching a fierce attack, wanting to start a decisive battle with Konoha .

But Tuanzang has always avoided fighting.

He ordered his troops to take advantage of the forest and mountain environment to engage in guerrilla warfare with Yunyin, and they had been circling in circles. Although there are frequent battles, the Konoha side is never in love with war, and if it can kill the opponent in a short time, it will fight, and if it can't be withdrawn, there has been no large-scale battle.

But.

Because of the numerical inferiority, the troops of the group were forced back at an extremely slow pace that was visible to the naked eye, and it would not be long before the battlefield shifted to the land of fire.

Because of the war, there were very few ninjas in Konoha Village, and even the Uchiha, who was part of the garrison, were heavily involved in the front line.

Some of the shinobi who were supposed to perform chores were also assigned to logistics.

A large number of wounded people are sent back to Konoha every day, and even though Konoha Medical Ninja is the best in the ninja world, there is a shortage of manpower.

The Sand Hidden Ninjas who interned in the hospital became tool men, and were often pulled into major surgeries by the attending doctor as interns.

It's just a start, but you can learn a lot.

After committing more than a dozen medical accidents at first, the interns gradually became familiar with the role of a doctor's assistant.

After all, they are all puppeteers, and they are proficient in human body structure and pharmacology, and they have a very fine control over Chakra, and they are also very comfortable learning medical ninjutsu.

……

"It's finally done!"

In the carry-on space, Ryuuji, who was in a mess and had dark circles under his eyes, couldn't help but feel excited, and waved his hand excitedly.

After two months, he finally thoroughly studied the sealing technique sealed in the crystal necklace of the first generation, and expanded and strengthened it to study the tailed beast sealing technique without defects.

He had expected that with the help of the Observatory, he would be able to accomplish this task quickly, but when he really understood the specific composition of this seal, he realized that its complexity was heavenly.

It's not as good as an artificial soul, but it's almost half as good.

It's no wonder that the entire ninja world has been studying for decades and has not been able to come up with a seal of the same level, so they can only try to steal it from the Vortex National Fire or Konoha.

If it weren't for the crystal necklace, which can be deduced and analyzed in reverse, and developed from scratch, it would have taken years or even decades to complete with the help of an observatory.

It can only be said that it is worthy of being passed down by the six immortals.

"With this thing, you don't have to worry about the situation of my Airo, and when other tailed beasts attack, there are also countermeasures." Long Erqiang endured his fatigue, saved the research materials, and then left the carry-on space.

"Ayaki-sama, Ayaki-sama......"

As soon as I left the carry-on space, I immediately heard a sharp knock on the door, and I seemed to be very anxious.

Did something happen?

Ryuuji frowned slightly, and had a bad premonition in his heart.

"Please come in."

Hearing the sound, the door was suddenly opened.

A middle-aged ninja rushed in and knelt down on one knee in front of Ryuuji.

"Lady Ayuki, the third generation of Kazekage-sama, he unfortunately died."
