After learning the yin seal, Yongze separated out a shadow avatar, let the shadow avatar use the yin seal, and finally delivered the chakra to the shadow avatar from the main body and stored it in the yin seal.

In this way, the Chakra problem of the shadow clone is guaranteed. As long as it is not attacked, it will last for a long time, enough for him to play Whitebeard well.

It is known that the domineering and domineering, the ninja world can attack his shadow clone, all of them are the top powerhouses of the five major ninja villages, and those people are not easy to meet.

He is also going to visit various small countries, not going to the big country like the land of the wind.

An ordinary shadow clone is still too reluctant, and it is not the main body.

Losing a shadow clone is a trivial matter, and the cloud cutter is not cheap, adding a lot of chakra metal.

Possibly the largest chakra metal weapon in the Naruto world.

After all, normal people won't use such big weapons, and the Chakra metal weapon itself has an extended function.

After solving the problem of the Yin seal, Yongze devoted more energy to two other things.

One is the development and research of breathing methods.

The breath of the sun is powerful.

After gaining the knowledge of pirates and ninjas at the same time under the talent of Jiguoyuan, it pushed the power of the breath of the sun to a terrifying level.

Even with such a strong physique, using the improved Sun's Breath, he can feel the rapid passing of physical strength and the pressure on his body.

Coupled with the attempt on the pocket, it has indeed proved that the breath of the sun is really not easy to practice.

Therefore, it is necessary to develop other breathing methods.

Breathing method should not be underestimated. Ordinary people, holding a knife, chopped a big stone three or four meters high, it would definitely be broken by the knife, and the stone would be safe and sound.

But if it is a swordsman who knows how to breathe, he can cut three or four meters of stone cleanly with a knife.

And this level is Tanjiro's level at the beginning of the plot to participate in the ghost killing team assessment.

Is this still not practicing full concentration breathing? Tanjiro before Changzhong.

After learning Changzhong, there will be a big improvement.

Gathering the ninjas with sword skills together to form a swordsman team, all of whom learn breathing techniques, is also a strong force.

You know, his breathing method is still an enhanced version of the Chakra system, and when combined with Chakra, it has a more terrifying improvement than the original version.

Moreover, due to the long-term use of breathing method, it can strengthen the body very well, which can make people who practice breathing method have more chakra.

Because chakra is an energy produced by the combination of spiritual energy and physical energy.

Although Jiguoyuanyi is the breath of the sun, in fact, the five basic breathing methods also come from Jiguoyuanyi.

At the beginning, Jiguo Yuanyi wanted to give all his swordsmanship and breathing techniques to the ghost killer team, but no one could learn his breathing of the sun.

Therefore, Jiguoyuan changed the breathing method according to each person's field of expertise, and gave guidance, and then the five basic breathing methods appeared.

The five basic breathing methods have their own merits. Although the water breathing is not strong, it can continue like a trickle of water.

The strongest breath of thunder is the explosion, which is the fastest and most explosive breathing method among the basic breathing methods.

Breath of Fire has a powerful attack and is the closest basic breathing technique to the characteristics of Breath of the Sun.

Taking into account the versatility of water breathing, Yongze first developed water breathing. Sure enough, Kao, who had been unable to enter Japanese breathing before, quickly mastered water breathing.

Next, what he wants to develop is the breath of thunder and the breath of wind.

Breath of the Rock and Breath of Fire, among which the Breath of Rock is difficult to cultivate, and I am afraid that only people like Matekai can cultivate it, and Breath of Fire, because there are no ghosts in Hokage, the characteristics of close to the breath of the sun become not so. powerful.

Another thing is the research on the secondary intercolumnar cells and the writing wheel eye.

The last experiment was successful, and they brought back the No. 1 experiment to Konoha and conducted a series of tests.

For example, the test of the speed of wound healing, the test of recovery chakra speed, the test of whether the broken limb can be reborn...

In the end, it was concluded that the speed of wound healing was much faster than that of ordinary ninjas, but it still could not achieve the level of rebirth from severed limbs.

After testing these, Orochimaru buttoned the writing wheel eye of the No. 1 subject and began to test the No. 2 subject.

Experiments, of course, can't only test one person, in fact, the conditions are not allowed, otherwise they may conduct experiments on five people at the same time.

But there is only one pair of writing wheel eyes, so naturally we can only experiment one by one.

But unfortunately, after the second experiment body was equipped with a writing wheel, it was not able to resist the erosion of the cells between the secondary columns, and finally died in the culture tank.

Although Orochimaru and Yongze were a little disappointed, they quickly entered the third experiment.

The third experiment was a success, and the No. 3 experimental body also possessed the strength of the artifact level. It only needs to adapt and learn the wood escape to become the real shadow level.

But the fourth experiment failed again, and Subject No. 4 died.

Orochimaru frowned. The 50% mortality rate was still only four in total. There might be a big error. This was not the result he wanted.

Those results were ultimately used on him. The secondary column cells had a 50% mortality rate, and the column cells were still worth it.

For the matter of life and death, Orochimaru doesn't want to gamble, he wants to be 100% successful.

So in the fifth experiment, both of them were trying to figure out how to solve this problem.

At this time, it happened that Yongze's shadow clone also stored Chakra for a month.

This month, because Yongze sends a large amount of Chakra to the shadow clone every day, the chakra in the shadow seal of the shadow clone has accumulated to a huge amount.

Yongze thought, since you want to send shadow clones to play roles to improve integration, why not just let shadow clones do something useful at the same time.

During the Third Ninja World War, the war between Iwa Ninja and Konoha was fought on the border between Kusano and Fire.

So Madara's base should also be in the country of grass.

Although Madara should be dead at this time, it is possible that the things in the base were taken away by Obito.

But it is also possible that Obito gave up that base, and these writing wheels are still stored in it.

Then he can see if he can find the base and steal some sketches.

Experimenting one by one is too time-consuming and the progress is slow.

Thinking of this, Yongze let the shadow clone pick up Cong Yunqie and head to the country of grass.

………………

………………

On the border of the country of fire, an unusually tall man with a peculiar white crescent beard walked on the road holding a naginata that was longer than his tall stature.

This time, Yongze did not choose to transform into a younger version of the white beard, and he was also an old white beard, but the height was still adjusted, still 2.3 meters.

It is still the template of the top war period, then it must conform to the appearance of the top war period.

The clothes are also the white coats and yellow pants worn during the war.

In terms of image, Yongze is extremely similar this time.

Pedestrians on the road saw the large muscles exposed on Yongze's chest, and the large Naginata sword in his hand, and kept a distance of more than five meters from Yongze, lest Yongze suddenly slash at them with a knife.

After walking for a while, Yongze saw a small settlement and walked into the settlement.

In the settlement, Yongze saw a tavern. There were many carriages parked in front of the tavern. It seemed that there might be a lot of people inside. Yongze thought about it and walked into the tavern.

Whitebeard is a big drinker, and if he doesn't go into a tavern when he encounters it, of course not.

This time, he was going to act the whole time, not the last time.

Yongze bent slightly and walked into the tavern.

Because it is next to the national border, there are all kinds of bulls, ghosts, snakes and gods in the tavern.

Yongze saw people in various costumes inside, with a bandit look, a bandit with a knife next to him, talking loudly and drinking.

There is also a look of indifference, no forehead guard, but a wandering ninja with chakra and a small cup of drinking alone.

There is also a large group of people who may indeed be caravans, gathering to drink.

Yongze's entry attracted the attention of a large number of people.

Without him, the height of 2.3 meters is really outstanding, not to mention that Yongze still holds a Naginata that is taller than him.

Yongze picked a seat at random, and soon someone trotted in front of Yongze and said with a flattering smile:

"My lord, do you need anything?"

"Gu la la la, bring up the best wine you have here, the bowl needs to be bigger, if you don't have it, just bring up the wine!" Yongze laughed loudly.

"The best wine, okay, do you need anything else, sir?" The hall-runner continued to ask.

At this moment, the runners already feel that this person in front of him is a fool who can be cheated, and the price is not asked.

But after looking at Yongze's body shape and muscles, the running hall finally felt that it was better not to die.

"Put the wine on first," Yongze said.

"Guests wait a moment, I'll get it right away." Paotang trotted away with a flattering smile.

Soon, the walker came up with three white vials and a bowl.

Yongze picked up a white vial, and the white vial was on his wide palm, as if it were an oral liquid.

Yongze directly drank the small white bottle of wine in one gulp and shook his head, which was not as good as the one he drank last time in the Kingdom of Chuan.

But after all, it is in the border area, and some of them sell well. Yongze didn't say anything, just let more people go to the hall.

At this time, a young man with a blushing face walked to Yongze's side and asked:

"Grandpa, you look so old, and you can still drink so much, is there any secret?"

The young man's action frightened the people who were with him enough. A middle-aged man who looked a little vicissitudes of life quickly walked to the side of the young man, covered the young man's mouth, and apologized to Yongze:

"Sir, I'm sorry, he drank a little too much and bumped into you."
