On the night of the Nine-Tails, I shattered the Tailed Beast Ball with a single punch.

After being infused with chakra, it became unusually excited.

"It's gone, it's gone," Tsunade said, shaking her hand.

"Didn't you say you wanted to eat?" Shizune asked, scratching her head.

"Eat my ass! Who would want to eat a fish used for practicing medical ninjutsu, especially one that's been sealed with a jutsu? Throw it away right now!" Tsunade rolled her eyes.

She was just saying it casually, but she didn't expect Shizune to actually believe it.

"Okay." Shizune obediently threw away the black fish as Tsunade had instructed.

Chapter 140 The Role Played Again

After learning the Yin Seal, Nagasawa created a shadow clone and had it use the Yin Seal. Finally, his main body transferred chakra to the shadow clone and stored it within the Yin Seal.

In this way, the Shadow Clone's chakra problem is guaranteed. As long as it is not attacked, it can be maintained for a long time, enough for him to properly impersonate Whitebeard.

With his Observation Haki, those in the ninja world who can attack his shadow clones are all top-tier ninjas from the five great ninja villages, and those are not easy to encounter.

He only planned to visit various small countries, not large countries like the Land of Wind.

A simple shadow clone is too much of a stretch, since it's not the real body that's involved.

Losing a shadow clone is a trivial matter; that Murakumogiri sword is not cheap, as it contains a large amount of chakra metal.

It may be the largest chakra metal weapon in the Naruto world.

After all, normal people wouldn't use such a large weapon, and chakra metal weapons themselves have the function of extension.

Having resolved the issue of the Yin Seal, Yongze devoted more of his energy to two other matters.

One is the development and research of breathing techniques.

Sun Breathing is very powerful.

Having acquired the talents of Yoriichi Tsugikuni and the knowledge of both pirates and ninjas, he pushed the power of Sun Breathing to a terrifying level.

Even with his strong physique, he could feel his stamina rapidly depleting and the pressure his body was under when using the modified Sun Breathing.

Furthermore, the experiment on Kabuto has indeed proven that Sun Breathing is truly difficult to master.

Therefore, it is necessary to develop other breathing methods.

The breathing technique should not be underestimated. An ordinary person, holding a knife, can easily cut a three- or four-meter-high boulder, while the knife will remain intact.

However, a swordsman who knows breathing techniques can cleanly and efficiently slice through a three- or four-meter-long boulder with his sword.

This level is the same level Tanjiro was at when he first went to participate in the Demon Slayer Corps auditions at the beginning of the story.

This is Tanjiro before he mastered the Complete Concentration Breathing Technique.

Once you master the common method, you'll see a significant improvement.

Gathering together ninjas with swordsmanship talent to form a swordsman squad, and having them all learn breathing techniques, would make them a formidable force.

It's important to know that his breathing technique is an enhanced version incorporating the chakra system, and when combined with chakra, it has an even more terrifying improvement than the original.

Furthermore, long-term use of breathing techniques can effectively strengthen the body, allowing practitioners to accumulate more chakra.

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

Although Yoriichi Tsugikuni is proficient in Sun Breathing, the five basic breathing techniques actually originated from him.

Yoriichi Tsugikuni originally intended to pass on all his swordsmanship and breathing techniques to the Demon Slayer Corps, but no one was able to learn his Sun Breathing.

Therefore, Yoriichi Tsugikuni modified the breathing techniques according to each person's area of ​​expertise and provided guidance, which led to the creation of the five basic breathing techniques.

The five basic breathing techniques each have their own merits. Although water breathing is not very powerful, it can be as continuous and enduring as a trickle of water. It is also the basic breathing technique with the most derivative breathing techniques, and it is also the easiest breathing technique to master.

Thunder Breathing's greatest strength lies in its explosive power; it is the fastest and most explosive breathing technique among the basic breathing methods.

Flame Breathing is a powerful attack technique and is the basic breathing method that is closest to the characteristics of Sun Breathing.

Considering the versatility of Water Breathing, Nagasawa developed it first. Sure enough, Kabuto, who had previously been unable to master Sun Breathing, quickly mastered Water Breathing.

Next, he will develop the Breath of Thunder and the Breath of Wind.

Rock Breathing and Flame Breathing are two different techniques. Rock Breathing is difficult to master, and probably only someone like Might Guy can achieve it. As for Flame Breathing, since there are no demons in Naruto, its characteristics, which are similar to Sun Breathing, are not as powerful.

Another matter is the research on secondary Hashirama cells and the Sharingan.

After their previous experiment was successful, they brought the first test subject back to Konoha and conducted a series of tests.

For example, tests on wound healing speed, chakra recovery speed, and the ability to regenerate severed limbs...

The conclusion was that the wound healing speed was much faster than that of an ordinary ninja, but it still couldn't achieve the level of limb regeneration.

After completing these tests, Orochimaru removed the Sharingan from the first test subject and began experimenting on the second test subject.

An experiment cannot, of course, be conducted on only one person; in fact, it's only because the conditions don't allow it, otherwise they might have conducted the experiment on five people at the same time.

However, since there is only one pair of Sharingan, they can only be tested one by one.

Unfortunately, even after the Sharingan was installed, the second test subject couldn't withstand the erosion of the secondary Hashirama cells and eventually died in the culture tank.

Although Orochimaru and Nagasawa were somewhat disappointed, they quickly moved on to the third experiment.

The third experiment was a success, and the third test subject also possessed pseudo-Kage level strength. He only needed to adapt to and learn Wood Release to become a true Kage level.

However, the fourth experiment failed again, and the fourth test subject died.

Orochimaru frowned deeply. A 50% mortality rate, with only four deaths in total, and a large margin of error, was not the result he wanted.

Those results will ultimately be used on him. If secondary interstitial cells have a 50% mortality rate, what will happen to the interstitial cells?

Orochimaru didn't want to gamble on matters of life and death; he wanted to be 100% certain of success.

So when conducting the fifth experiment, both of them were trying to find a solution to this problem.

At that moment, Nagasawa's shadow clone had also stored up a month's worth of chakra.

Over the past month, because Yongze has been supplying the shadow clones with a large amount of chakra every day, the chakra in the shadow clones' Yin seal has accumulated to a huge amount.

Nagasawa thought, since we're going to send out shadow clones to play the role of improving fusion, why not just let the shadow clones do something useful while playing the role?

During the Third Shinobi World War, the war between Iwagakure and Konoha took place within the Land of Grass and on the border between the Land of Fire and Konoha.

Therefore, Madara's base should also be located within the Land of Grass.

Although Madara should have been dead by then, Obito probably took everything from the base with him.

But it's also possible that Obito abandoned that base, and some Sharingan might still be stored inside.

Then he could go see if he could find the base and steal some Sharingan.

Conducting experiments one by one is too time-consuming and slows down progress.

With that in mind, Nagasawa had his shadow clone pick up the Kumogiri and head to the Land of Grass.

……

……

On the border of the Land of Fire, a man of unusually tall stature, with a peculiar white crescent-shaped beard, walked along the road, wielding a naginata even longer than his imposing frame.

This time, Nagasawa did not choose to transform into the younger version of Whitebeard, but instead became the older version of Whitebeard, adjusting his height to 2.3 meters.

Since it's based on the Marineford War era, it needs to conform to the appearance of the Marineford War era.

His clothes were the same white coat and yellow trousers he wore during the Marineford War.

In terms of appearance, Nagasawa looks extremely similar this time.

Pedestrians on the street, seeing the large muscles exposed on Nagasawa's chest and the large naginata in his hand, all kept a distance of more than five meters from him, fearing that he might suddenly slash at them with his sword.

After walking for a while, Yongze saw a small settlement and went into it.

Within the settlement, Nagasawa spotted a tavern with several carriages parked in front, suggesting that there might be quite a few people inside. After a moment's thought, Nagasawa entered the tavern.

Whitebeard loved to drink, so it was unacceptable for him to not go into a tavern when he came across one.

This time he's going to play the role the whole time, unlike last time.

Yongze bent slightly and walked into the tavern.

Because it's located near the border, the tavern is filled with all sorts of strange and unsavory characters.

Inside, Nagasawa saw people dressed in various ways, including bandits with a bandit-like air about them, knives beside them, and loud talking and drinking.

There was also a wandering ninja with a calm expression, no headband, but chakra, drinking alone from a small cup.

There was also a large group of people who were probably from a caravan, drinking together.

Nagasawa's arrival attracted the attention of a large number of people.

There's no other reason than his outstanding height of 2.3 meters, not to mention that Nagasawa is wielding a naginata that's even taller than him.

Yongze randomly picked a seat, and soon someone ran up to him, smiling obsequiously:

"Sir, what do you need?"

"Gulp gulp gulp, bring out your best wine, and bring out big bowls. If you don't have any, just bring out the wine itself!" Yongze laughed loudly.

"The best wine, yes, is there anything else you need, sir?" the waiter continued.

At this point, the waiter already felt that the person in front of him was a sucker he could rip off, so he didn't even bother to ask the price.

But after looking at Nagasawa's physique and muscles, the waiter ultimately decided it was best not to tempt fate.

"Let's serve the drinks first," Yongze said.

"Please wait a moment, sir, I'll go get it right away." The waiter, with a fawning smile, jogged away.

Soon, the waiter came up with three small white bottles and a bowl.

Yongze picked up a small white bottle, which looked like an oral liquid in his large palm.

Nagasawa downed the small white bottle of wine in one gulp, shook his head, and said it wasn't as good as the wine he had in the Kingdom of Rivers last time.

However, since it was a border area, it was good that there was anything to sell, so Yongze didn't say anything, but just told the waiters to serve more.

At this moment, a young man with a slightly flushed face walked up to Yongze and asked:

"Grandpa, you look so old, yet you can still drink so much. Do you have some secret?"

The young man's action startled those around him. A middle-aged man who looked somewhat weathered quickly walked over to the young man, covered his mouth, and apologized to Yongze:
