Naruto, this is called Kuuga, not White Zetsu

"Qing, can you see how much chakra is left in Chihiro's Chuunin body?"

Tsunade was a little worried. Although the thick fog disappeared quickly under Chihiro's Fire and Wind Styles, it was still very difficult to maintain such a large-scale Fire Style with only the chakra of a senior ninja.

A member of the Hyuga clan named Qing hurriedly checked, and after repeatedly opening his Byakugan several times, he confirmed: "Tsunade-sama, Chihiro's chakra did not decrease due to the use of Fire Release... On the contrary, it is slowly increasing!"

"What did you say? The chakra has not decreased, but is still increasing!" Tsunade's pupils suddenly widened, and Shikaku beside her also looked unbelievable.

"Yes, Lady Tsunade, I opened my Byakugan several times, and I am sure I saw it correctly."

At this moment, Tsunade frowned as she looked at the Fire Style in front of her. The chakra did not decrease but increased, and was still increasing. Even the Flame Pillar had a tendency to expand.

Is there really such a ninjutsu in this world? Or is this the bloodline limit of that kid?

The slug's soft voice sounded on Tsunade's shoulder: "Lady Tsunade, this fire escape may not be released by chakra, but by using natural energy."

Tsunade asked back, "Natural energy? Are you talking about fairy arts? Which fairy arts among the three holy places?"

Shikaku and Kiyoshi on the side did not say anything, but just listened quietly to the conversation between Tsunade and the slug.

"No, Lady Tsunade, what I meant is that Lady Chihiro directly used natural energy to create such a powerful fire jutsu. There is no trace of chakra used in it."

Although it was the first time he saw a human using natural energy, the slug believed that he was not mistaken.

The moment she was summoned by Tsunade, she felt that the natural energy in this environment was extremely active, and she could even form a fire escape of this scale.

It was not until the thick chakra fog continued to dilute that she realized that humans were using natural energy to release ninjutsu.

Tsunade was silent for a while: "Simply using natural energy, I remember that pervert Jiraiya said that it is very dangerous to rashly use natural energy without formal channels and a large amount of chakra!"

The mini slug nodded. "I can feel that the chakra in Chihiro's body has gradually transformed into fairy chakra, but it has not yet been completely transformed. Now that natural energy is used on a large scale and frequently, it will eventually become a part of nature."

Natural energy exists everywhere in the ninja world. It exists gently in this world, but once it enters the body of a living organism without natural energy, it will become violent.

Slug was very curious about Chihiro. This was the first time she had seen a human being who could integrate natural energy into his body and use it directly.

“Becoming part of nature?”

"Yes, the body will gradually turn into various things such as stone, tree, etc., and once it becomes part of nature, there is no way to recover."

After hearing the slug's explanation, Tsunade felt disappointed. In her early years, she also hoped to learn fairy techniques from the slug to keep herself young.

But despite the slug's careful teaching, she just couldn't learn it, and couldn't even sense the first stage of natural energy. The slug's words just now reminded her of the place full of swollen slug stone statues when she was learning fairy arts.

If I'm not mistaken, those are the slug stone statues that were transformed because of failure in learning the "Wet Bone Forest" magic.

If she had known from the beginning that Chihiro would use natural energy to disturb the fog in the basin, she would never have let him enter the basin.

Tsunade now feels a little guilty, as her new disciple is likely to leave her.

"Sir Slug, Chihiro hasn't completely turned into a stone statue yet. If, as you said, he completely masters the immortal technique, can this be avoided?"

Shikaku noticed Tsunade's emotional change and hurriedly asked her a question that he was also concerned about.

The Nara clan also had records of magical arts, but they had no channels to learn them. Now there happened to be an opportunity to learn about natural energy and magical arts.

Tsunade's eyes lit up and she looked up at the slug on her shoulder.

The slug shook his head: "I'm sorry, Master Tsunade, most humans first sense natural energy, then master the Sage Mode step by step, and finally use Sage Chakra. Even after going through so many steps, they only use natural energy indirectly by combining chakra with natural energy."

"but..."

"Master Chihiro is different. He doesn't have complicated steps and directly uses natural energy. I don't know if practicing Sage Mode is useless to him. If I hadn't seen it with my own eyes, I wouldn't even believe that such a human being exists..."

Qing interrupted the slug's speech and reported the situation on the battlefield: "Tsunade-sama, the Mizukage is heading in the direction of Chihiro-sama,"

Tsunade looked stunned, took a deep breath, and rushed towards the battlefield holding two slugs...

Tsunade was not the only one who noticed the Mizukage's actions. Seto Chihiro also sensed a huge amount of chakra coming towards them. He had not stopped using Tower Blast during this period.

Natural energy continuously enters the body, and the Tower of Blast continuously requires natural energy, and the two form a subtle relationship.

He felt that the power of the tower's explosion could be further increased by actively drawing on the natural energy deep within the earth.

But he didn't. Compared to last time, after his chakra amount increased, the natural energy contained in his body was also slowly increasing. If he rashly used natural energy beyond the limit of his body, he would most likely turn into stone.

Seto Chihiro did not forget that he had the Aguru Belt which made him immune to petrification, but now was not the time to just use Tower Blast and end it.

"Um?!"

Seto Chihiro sensed a large amount of chakra rushing towards him from the direction of the Mist Ninja, and then Tsunade also ran towards him.

It is not difficult to guess that the person coming from the opposite side is the Mizukage. On the entire battlefield, the only one who can attract Tsunade's attention is Yagura.

After canceling the 'Arc of the Great Tree' and applying the last bit of natural energy in her body to the Tower Explosion, Seto Chihiro shouted loudly in the direction of Mikoto: "Captain Mikoto, the Mizukage is coming, move back quickly."

As soon as he finished speaking, Tsunade appeared behind him.

"Chihiro, this is for you. Go back to Shikaku and get some rest."

"what?"

Before Seto Chihiro could react, something soft fell on his head.

He used the moonlight to take a closer look and saw a blue and white creature the size of a palm, shaped like a slug. A cheerful female voice also rang in his ears.

"Hello, Master Chihiro. I am Master Tsunade's summoning beast."

"Hello, I..."

boom!

Before Seto Chihiro had the chance to introduce himself, a familiar voice rang out, it was the sound of someone being knocked away by a fist.

Under the moonlight, Mikoto was running towards the fallen Tsunade, while the 'Tsunade' beside Yagura turned into vapor and disappeared.

Chapter 45: Fighting (4300 words)

Inside the basin, the Mist Ninja and Konoha Ninja all joined in the battle, screams, wails, and roars were heard one after another.

In the first round of the battle between Tsunade and Yagura, Tsunade was knocked away by Yagura's "Water Mirror Technique".

"Lady Tsunade, you are not hurt, are you?"

"I am fine."

Tsunade slowly stood up with the help of Mikoto. She was covered in dust and her clothes were tattered from being worn by the ground. She looked much more disheveled. She moved her eyes from Yagura to the Uchiha member beside Mikoto.

"Mikoto, ask the Uchiha members around you to support other ninjas, and you will be in charge of holding my hand..."

"Water escape. Big blast of water!"

It was obvious that Tsunade wanted to change her tactics, but the Mizukage did not give her this opportunity.

Yagura raised his hand and pressed the end of the stick with the flower on it to the ground.

Under the gaze of Seto Chihiro, after a simple hand seal, the power called Great Explosion Water Wave was released from the end of the stick.

A large amount of water flowed out from the end of the stick, lifting Yagura off the ground like a fountain and floating on the huge column of water.

Layers of waves continued to emerge from the bottom of the water column and rushed towards Tsunade.

"Earth Escape. Earth Flow Wall."

Seto Chihiro concentrated her chakra on her legs, leaped in front of Tsunade and Mikoto, and quickly formed seals with her hands.

After a tremor under the feet, the ground continued to rise, and the tall walls successfully resisted the attack of the waves, but the Goji Yagura above the water column was also constantly attacking this side.

A green light appeared at Seto Chihiro's feet, attracting the attention of the slug and Tsunade above his head, and he stretched out his right hand and condensed natural energy in his hand.

"Fire Style. Great Fire Dragon Technique!"

"Star Explosion!"

Using the fire dragon head released by Mikoto as cover, white balls of light kept flying out of Chihiro's hands and followed behind the fire dragon head, and the distance of a hundred meters was fleeting.

"Water escape. Water formation wall!"

The water escape technique of this Mizukage can be said to be perfect. After a simple hand seal, a curtain of water rose from the waves under his feet.

Chi~~Chi~~Bang! Bang! Bang! ...

The huge fire dragon head hit the water curtain, and a large amount of water vapor appeared in the center of the battlefield, followed by an explosion.

The thick water column swayed in the explosion, and a figure emerged from the white mist and stood on the water. However, after losing Yagura's control, the water column collapsed in less than two seconds.

"What a terrifying water jutsu! He can even use the Water Array Wall while continuously using the Great Explosion Water Wave. If it weren't for the ninjutsu that Chihiro used later, I'm afraid there would be no way to stop the water jutsu of this Mizukage. It's not hard to imagine that a small lake would form later."

Mikoto stood there looking at the water that was flowing toward the center of the basin due to the terrain, and she still felt a lingering fear.

In the face of such a powerful water jutsu, her fire jutsu had no way of breaking through the water curtain.

The slug on Chihiro's head suddenly brought Kakashi's battle report: "Tsunade-sama, Kakashi-sama sent a message that some Mist Ninjas, with the help of the Kaguya clan, are about to break through their defenses. I hope you will be prepared and be careful."

After Seto Chihiro used the Tower Blast, Kakashi, Yamanaka Inoichi, and Akimichi Choza led the ninjas who could participate in the battle to prevent the Mist Ninja from releasing the Mist Hidden Technique, and at the same time divided the battlefield.

Tsunade stared at the water, at the Mizukage who was panting because of the star blast, and turned her attention back to Chihiro, a look of worry crossing her face.

This kind of ninjutsu that releases natural energy continuously is unheard of. Ignoring the side effects, it is simply a perfect ninjutsu.

However...if this side effect doesn't disappear within a day, it will become a forbidden technique.

"Chihiro, stop it."

"But teacher..."

"Stop, Chihiro..." Tsunade's voice was a little strong.

"I understand, teacher..."

When Mikoto heard the word "teacher", she opened her eyes wide and said nothing.

Tsunade looked at the environment created by the huge water shock wave, which indirectly enhanced the output of the Mist Ninja, and for the first time she felt extremely disgusted with her hemophobia.

Whether he is fighting the Mizukage alone or a group of Mist Ninjas alone, as long as he doesn't see blood, he won't have any big problems.

But...the Tailed Beast Balls had already left some of the Konoha ninjas with very little chakra in their bodies. Judging from the water jutsu attainments of this unknown Mizukage, it is absolutely impossible for the Mist Ninjas and the Mizukage to meet up, not to mention that those who will be meeting up are all elites among the Mist Ninjas.

If the Mizukage cannot be defeated in a short period of time, and if various Mist Ninjas appear later, things will definitely become more complicated.

Tsunade handed the slug in her hand to Mikoto, and put her hands on Chihiro's shoulders, forcing the two pairs of eyes to look at each other: "Don't use this forbidden technique again. For you, this forbidden technique will endanger your life. Leave it to me from now on. You and Mikoto will hold back these Mist Ninjas, and I will intercept the Mizukage here by myself and defeat him."

Seto Chihiro couldn't help but raise her voice: "But, given your condition, can you really defeat the Mizukage? You were just knocked away by your own ninjutsu."

Tsunade heard the hidden meaning in Chihiro's words and knew that her disciple was concerned about her, but she still couldn't help but look dark.

Seto Chihiro placed the slug on her head on Tsunade's body, shifted her sights from Yagura who was nearby to the Mist Ninja in the distance, and nodded seriously: "But forget it, since you said so, Teacher Tsunade, I will do as you say."

"Tsunade-sensei, if my guess is correct, the figure that looks exactly like you and turned into a splash of water after attacking you may be able to copy your attack and disappear after using it once, especially against a Taijutsu type ninja like you."

Tsunade muttered to herself: "Will it disappear after being copied once..."

Her disciple's words reminded Tsunade of the scene just now.

A water mirror appeared in front of the Mizukage, and her figure seemed to appear on the water surface, and then she was knocked away by "herself".

"Tsunade-sensei, if possible, I hope you can lead the Mizukage to the woods. Only in this way can I support you and my ninjutsu will have a real effect."

After saying that, Seto Chihiro pulled Mikoto around Yagura and ran towards the four Mist Ninjas running towards them in the distance.

"Is it really...effective?" Tsunade was a little hesitant. She had originally planned to lead Yagura to the woods, but after hearing what her own disciple said, she suddenly didn't know what to do...

What if the disciple I just accepted becomes depressed because of her...

Glancing at Yagura who was moving slowly, Tsunade whispered to the slug in her arms, "Living slug, do you feel any changes happening inside Chihiro's body?"

One of the important reasons for giving the slug to Chihiro was to let the slug check his vital signs.

"Lady Tsunade, the natural energy doesn't seem to have any effect on Lady Chihiro's body..."

A doubtful voice came out of the slug's mouth, which was completely different from her previous guess.

Ordinary creatures, even those favored by natural energy, will be petrified when natural energy is used intensively.

But Tsunade's disciple not only did not suffer any negative effects, but seemed to have become stronger due to the effects of natural energy.
