The transplant did not go smoothly, and although it took a long time, Tsunade perfectly exchanged the circulatory systems of the two, and also transplanted a new sansho fish poison sac to Shin by the way. Fastest updates

Relying on his superb chakra control and professional medical knowledge, Tsunade used a chakra scalpel to accurately strip and transplant the circulatory system of the two men, and then treated it with medical ninjutsu, and after the operation was completed, there was not even any wound.

This kind of chakra manipulation force rope tree can also do it, but it is extremely difficult for him to find a circulatory system from the complex internal tissues, and even if he does, it is impossible for him to complete the operation within the stipulated time.

Therefore, this transplant operation would not have been successful without Tsunade.

The wound of the operation has been perfectly healed by medical ninjutsu, so the two of them can get out of bed and walk freely after the operation, but due to the large amount of blood loss and the system that the internal organs need time to adapt, the two need a period of admiration and cannot go through strenuous exercise.

Of course, the daily activities were not affected at all, so Yahiko continued to conduct the investigation work in Konoha as usual in the following days, without arousing anyone's suspicion. Except for a few people involved, no one knew that an operation was performed that night that could change the pattern of the entire ninja world.

Yahiko then spent more than a month in Konoha, during which time he took time to learn Hanzo's secret art while cultivating.

The circulatory system of self-belief is more perfect for the control of the poison sac, and during this period, Yahiko has not had any accidents of poison gas leakage, and can communicate with everyone normally, and does not need to wear a gas mask for a long time like Hanzo. In addition, Yahiko's external control of the Sansho fish toxin is also more refined, in addition to using chakra to create toxins to increase the virulence, he can even integrate the toxin into the chakra to issue a poisonous attack, which is more powerful if combined with the six types. In this way, even enemies who have taken the antidote in advance will be able to use the corrosive effect of the toxin to deal damage.

A month later, Yahiko's body fully recovered and mastered the abilities of the toxin. Moreover, in this month, with the assistance of a large number of Qi Cultivation Pills provided by the Rope Tree, the chakra amount of Yahiko and the three of them has increased from the upper ninja to the shadow-level realm! The secret techniques mastered by the three of them can completely compete with the shadow level, and after having the matching chakra, the combat power has officially entered the shadow level, especially Yahiko, who has reached the shadow level standard in terms of physical attributes, coupled with a wide range of toxin attacks, is already a young version of Hanzo, and what is lacking is only combat experience.

At the beginning of February of Konoha 44, the three Yahiko, who had greatly increased their strength, ended their two-month visit and returned to Yuyin Village with the mission.

On the day of the mission's departure, Konoha held a grand farewell ceremony under the leadership of Rope Tree, and the alliance between the two sides ended perfectly, if it had not been for an unexpected ambush behind.

…………

After bidding farewell to Konoha ......, the three of Yahiko led the mission through the forests of the Fire Country.

Seeing that he was about to reach the border of the Land of Rain, Yahiko suddenly let out a low shout: "Stop! ”

Hearing Yahiko's order, all the rain shinobi stopped in place.

"What's wrong? Yahiko?" Nagato asked, a little confused.

The other rain ninjas also looked at their leader with puzzled expressions.

"Be on your guard! Don't you think this forest is too quiet? Not to mention the beasts along the way, not even a single bird call?" Yahiko said cautiously to everyone while looking around.

After being reminded by Yahiko, Yunin quickly set up a defensive formation and surrounded the three of Yahiko in the center.

As soon as the formation of the rain shinobi was completed, the attacks followed! "Whoosh...... A large number of ninja equipment burst out from all directions like raindrops. This kind of covering attack can't be dodged at all, and the three of Yahiko may be able to resist with their shadow-level strength, and the other rain ninjas in the mission will inevitably suffer heavy losses.

"Nagato!" Seeing that the attack was imminent, Yahiko stood still and did not make a move, but shouted Nagato's name loudly.

I saw Nagato raise his right hand, and all the ninja equipment in the sky stopped in the air as if time had been frozen, and then it burst out in all directions.

For Nagato, who had mastered the Shinra Celestial Sign, any physical attacks did not work, and after Chakra reached the shadow level, Nagato's use of the Reincarnation Eye became more relaxed. If it was used in the past, it would have caused a great load on his body, but now it only consumes a large amount of chakra.

The ninja that bounced off the "chop chop ......" shot on the surrounding trees, making a muffled sound, and the rain ninja who was attacked by the sneak attack was unscathed.

"What people! Come out! Yahiko let out a loud shout at the surrounding forest.

"Huh! The leader of Yuyin Village is really not simple, but I didn't expect that red-haired guy to be the strongest among you! A gloomy voice rang out.

A large number of ninjas appeared from the shadows, on the trees and on the ground, completely surrounding the rain ninja in the center.

These ninjas were dressed in gray vests, with various masks on their faces, and exuded a gloomy and cold aura all over their bodies, and at least a few hundred people looked at the past.

"Konoha Shadows?" Yahiko looked at the ninjas around him and said with a serious face, "Why did you attack us?" Aren't you afraid that the alliance between the two countries will be destroyed?"

Yahiko used words to attract the attention of the roots, and at the same time secretly made a gesture to the surrounding rain shinobi.

"Humph! Ally? You don't deserve that title at all! The root of the leader said in a cold voice: "What qualifications does the country of rain have to be on an equal footing with Konoha?" Completely integrating into Konoha like the country of the sky and the country of the river is the fate of you small countries! Destroy the leader of the Land of Rain and annex the Land of Rain on the orders of Lord Joshu-sama! ”

"Hehehe!" Hearing this, Yahiko sneered, "I'm afraid you are not some dark department, but the notorious root of Danzang's subordinates, right?" How can any shadow department foolishly reveal their mission to their target? Is Tuanzang trying to plant a rope tree? Rope-sama wouldn't do such an unwise thing. ”

The root of the leader stiffened when he heard this, and then said coldly: "Hmph! Don't know what you're talking about? Anyway, none of you can escape today, even if you tell you the truth, what can you do? For the sake of Konoha, how could Lord Rope Tree take care of that little relationship between you?"

"Hey! That masked man with a hidden head and tail, don't be hard-mouthed! Our relationship with the rope tree is not something you can understand! How could he have sent someone to ambush us?

If we don't stabilize the situation, Konoha will soon be besieged by the major powers, right?

This kind of idiotic thing, only that old guy from Tuanzang would do it, right? No wonder the rope tree said he liked to die. Xiao Nan said with a sneer.
