As Uchiha You puffed up his chest, a line of hot fire came out of his mouth and passed through the strange hand seals formed by his hands.

At the moment the handprint passed through, the fire line suddenly expanded and widened, spreading out like a horn.

But when the super-powerful fairy chakra was filled in, the temperature of the flame did not drop at all, but became even stronger and more fierce.

The thin line of fire expanded into a raging sea of ​​fire dozens of meters high a hundred meters away, with a width of thousands of meters, and it was still extending to both sides.

Under Uchiha Yu's control, the front of the flame remained a wide plane without any obvious protrusions.

From the perspective of the Sand Village ninjas, the sea of ​​fire looked more like a huge wall of fire, advancing towards them at high speed.

The huge wall of fire contained immeasurable heat, and the radiated light distorted the air, creating a mirage-like scene.

Looking from behind Uchiha You, the Sand Village ninja became shadowy and even twisted like a snake, which was extremely weird.

But soon the flames spread further, and the Konoha ninjas' vision was completely occupied by the huge wall of flames, and they could no longer see the Sand Village ninjas.

They immediately felt the heat radiation coming towards them, which instantly evaporated the water vapor and caused the air temperature to suddenly rise by 40 to 50 degrees.

The Konoha ninjas all felt uncomfortable, as if they had entered an oven, and their breathing was completely messed up.

Inhaling hot air would cause burning pain in my nostrils, so I had to switch to mouth breathing, but each time my mouth would be completely dried out and it was not an comfortable feeling.

The exhaled waste gas is cooled in the lungs and exchanged with water vapor in the blood, making the nose and mouth feel comfortably cool and moist.

Aburame Shiwei took a breath of the burning air and felt that he had to quickly recycle the parasitic bugs that had spread out into his body to prevent them from being ignited as the temperature continued to rise.

The wall of sea of ​​fire advanced forward, its speed seemingly slow, but in fact it was far beyond the limit of ordinary ninjas, and it soon swept across the area of ​​the Sand Ninja.

Uchiha You's spitting lasted for a full three minutes, until he used up the senjutsu chakra he had synthesized this time, and then he closed his mouth.

Without the constant supply of chakra, the fire lasted only 30 seconds before being quickly extinguished.

When the sea of ​​fire disappeared and vision was restored, the Konoha ninjas were all stunned.

In front of them, the earth was burned so thoroughly by the sea of ​​fire that any protruding objects on the earth disappeared, the trees turned into ashes, and the rocks turned into lava.

The ground was covered with cracks, through which flowed red magma and emitted billowing hot steam.

On the rock remnants between the cracks, crystals that had begun to condense were sparkling, as if they had been forged into glass.

Most importantly, all the Sand Village ninjas disappeared.

The sea of ​​fire covered a very large area, and except for the ninja at the back, most ninjas could not escape by using the technique of instant body movement.

As long as they cannot fly or have not mastered the space-time ninjutsu, they can only endure the burning of flames.

Obviously, none of the trapped Sand Ninjas could withstand such violent flames, and they didn't even leave the slightest trace.

Clothes themselves are flammable, and the human body is also flammable in high temperatures. Various weapons, ninja tools and other metal objects have melted in the lava.

Uchiha Fugaku stared at the scene in front of him in amazement.

He couldn't believe that someone could defeat a ninja army of more than 4,500 people with just one ninjutsu, with thousands of ninjas either dead or escaping.

This is exactly like the legendary Uchiha Madara.

Uchiha Fugaku swallowed hard, but found that there was no saliva in his mouth. The hot air and nervous mood made his saliva completely dry up.

Now he was finally completely convinced.

Not only Uchiha Fugaku was convinced, but basically all the Konoha ninjas present were also completely convinced and full of admiration for Uchiha Yu's power.

At this time, only Minato Namikaze still had the fighting spirit to catch up with or even surpass Uchiha Yu.

Soon, another ninja appeared who shared the same belief as Minato.

"Fourth Hokage-sama!"

Orochimaru walked over with his hands folded and a depressed look on his face. When he heard the shouts of the Konoha jonin, he just nodded lazily.

He walked up to Uchiha You and complained to him, "I know You-kun is very powerful, but if you want to make such a big scene, shouldn't you tell me first?"

Uchiha You asked curiously: "What went wrong?"

Orochimaru pointed to both sides of the battlefield and said dissatisfiedly: "You know I am here to outflank us, the snake troops must be deployed to the sides of the battlefield."

"You actually started such a big fire. My people were almost dragged into it."

Uchiha You looked in the direction Orochimaru pointed, and sure enough, he saw some ninjas dressed as snake troops. They seemed to be cleaning the battlefield.

He didn't care about the Hokage, and naturally he wouldn't indulge Orochimaru, so he immediately retorted: "You can't blame me for this, this distance is not the right distance for a ninja to ambush and outflank."

"Orochimaru, you actually made the snake troops advance for a full 4 kilometers, almost reaching the feet of the Sand Ninja. Isn't it natural that I accidentally injured them?"

Who knew that Orochimaru suddenly acted like a rogue and said to Uchiha You: "I am the Hokage, I am the most powerful in Konoha Village! It is your fault that you did not tell me in advance, so you have to compensate me."

Uchiha You was so angry that he laughed, and said with great joy: "How can there be a Hokage who plays rogue like you?"

Orochimaru smiled and replied, "You were the first to act rogue."

"And it's really dangerous. If I hadn't done it myself, your fire would have definitely caused many casualties. Don't you appreciate it?"

Uchiha You patted his head. He knew that Orochimaru was playing a trick of two steps forward and one step back, but he was not completely without fault in this matter, so he was indeed a little embarrassed.

So Uchiha You asked, "Fourth Hokage, what exactly do you want?"

Orochimaru said with a serious expression: "I want your experience in practicing Wood Release, and your techniques for practicing Senjutsu."

Uchiha You knew it as soon as he heard it. The experience gained from practicing Wood Release was for Tenzo, and the skills of practicing Senjutsu were for himself.

"Fourth generation, do you think you will be free soon?"

"Well, with your performance, I am confident that I can destroy the Sand Village Ninja Army here, and then I can talk to the Fourth Kazekage and the Wind Daimyo."

"Soon, the west side of Konoha Village will be completely peaceful, and I will have more time. Of course, I will continue to study fairy arts, and I will also formally accept disciples."

"This time I will take in Uchiha Shisui, Mitarashi Anko, and the Wood Release kid from the Root."

Orochimaru looked at Uchiha Yuu and added, "It is the formal fulfillment of the previous agreement."

Uchiha You nodded and said, "I am very happy that you can fulfill the agreement seriously, Fourth Generation. But I have to be honest, you are asking too much."

Orochimaru heard the hidden meaning in Uchiha You's words and asked curiously: "So...what do you mean?"

Uchiha You smiled and said, "It costs extra money."

Orochimaru was amused: "Haha, Yu-kun's words are really interesting, what do you want?"

Uchiha You restrained his smile and said seriously: "I want Myoboku Mountain or Ryuchi Cave, and the Wet Bone Forest is not out of the question."

Orochimaru also became serious and said, "You-kun, you are asking for too much. According to your words, now you... have to pay more."

Uchiha You shook his head and said, "Fourth Generation, if I only want clues, that is, to sign my name on the contract book, I don't have to pay extra, right?"

Orochimaru denied, "You-kun, you and I both know that you can use the Flying Thunder God Technique."

"No matter which of the three holy places, as long as they give you the Book of Contract, it is equivalent to handing over this holy place to you."

“So, you have to pay more.”

Uchiha You nodded, agreeing with Orochimaru's inference.

Because they are both smart people, he never makes excuses in front of Orochimaru, and Orochimaru never lies in front of him, but simply does not tell the whole truth.

Since the truth that he didn't tell was guessed by Orochimaru, Uchiha You would never deny it.

He asked, "Does the Fourth Hokage want the secret of immortality, or the secret of the ninja world?"

Uchiha You's question hit Orochimaru's sore spot directly, and his heart even stopped for a moment. He wanted the secret of immortality and the secret of the ninja world.

Unfortunately, Orochimaru knew that the only bargaining chip he had was the Ryuchi Cave, and he could not exchange two secrets at the same time.

Whether it is Tsunade's Book of Contract of the Wet Bone Forest or Jiraiya's Book of Contract of Mount Myoboku, Orochimaru can actually get them.

But Orochimaru knew Uchiha Yu's true nature, and knew that when it came to something he cared about, the first thing he would consider was eating.

When he sees anything, his first thought is whether it can be eaten, his second thought is whether it tastes good, and the last thought is what benefits can be gained from eating it.

Now that Uchiha You gets the chance to enter the holy land, the destruction of the holy land is only a matter of time.

The best outcome for the immortals would be like that giant octopus in the East China Sea, kept in captivity and harvested regularly.

If this really happened, Tsunade and Jiraiya would hate themselves to death.

Therefore, the only thing Orochimaru could offer for exchange was the Ryuchi Cave.

So which secret should be changed?

Orochimaru was unable to make a decision until the second wave of Sunagakure ninjas rushed over.

The long period of struggle made Orochimaru irritable. Looking at the Fourth Kazekage, Chiyo and Yekura walking in front of the Sand Ninja team, he stuck out his tongue and licked his cheek.

[Let’s kill someone first to have some fun, and then decide. ]

Orochimaru looked at the dark mass of Sand Village ninjas on the opposite side and asked, "Yu-kun, can you use the Fire Release just now to clear the field again?"

Uchiha You shook his head and replied: "Fire escape is not possible. My fire escape chakra has been exhausted. The most suitable ninjutsu now is wood escape."

"Um?"

Orochimaru turned around in surprise and looked at him carefully from head to toe. After a long moment, he confirmed in surprise, "Wooden clone?"

Uchiha Yu nodded.

"It's amazing." Orochimaru took a deep breath and exhaled slowly: "I always thought I knew you very well, but now it seems that I have always underestimated You-kun."

"I've decided. I want to know the secrets of the ninja world. I can also study the secrets of longevity myself."

"If You-kun can do it, so can I."

Uchiha You smiled and said: "Okay, then it's settled. After the matter of Sand Village is over, you, the Fourth Hokage, will make a deal with the original body."

"As for me, I'll just open the show for everyone."

The essence of the Wood Clone is Wood Release. Once Wood Release is used with all one's strength, the result will inevitably lead to the disintegration of one's own existence.

After the usual prelude, Konoha Village's signature ninjutsu was activated.

Wood Style: Advent of the Tree World

Along with the rumbling of the earth, countless big trees grew on the charred, lava-flowing, and devastated land.

Driven by Uchiha Yu's consciousness, the tree awakened its hunting instinct and actively sought out Sand Village ninjas to hunt and kill.

Once entangled, it will be dragged underground and tightly tied up in the layers of tree roots. Then, like wringing a towel, all the blood in the body will be squeezed out and become nutrients to nourish the continued development of the tree.

Among the ninjas present, only Orochimaru and Uchiha Fugaku had seen this scene, but they were still shocked by the brutality of the Tree World.

It turned out that last time, Uchiha You held back and did not deliberately drive the forest to kill people. The death of the Anbu and Root ninjas was just an instinctive reaction of the trees.

It turns out that the first Hokage who founded Konoha Village was so terrifying. No wonder the four major ninja villages would endure no matter how difficult it was.

It was not until the death of the first Hokage that the ninja village dared to start a war.

As the big trees swayed, the forest made a sound like waves in the sea, completely drowning out the screams of the Sand Village ninjas.

But the terror, despair, helplessness and other emotions of so many people being strangled to death had already been felt by the watching Konoha ninjas.

The sky seemed to be a little gloomy.

But Uchiha You, who had caused such a huge massacre with his own hands, didn't care at all. He was never afraid of dead people, but only worried about the powerful cause and effect and the disgust of heaven and earth.

But he had already confirmed that when fighting against hostile ninjas who actively entered the battlefield, no matter how exaggerated the killing was, it would not be despised by heaven and earth.

Because Heaven’s heart is the heart of everyone.

Of course, human hearts cannot determine the will of heaven. Human hearts are fickle and changeable, making them the most chaotic existence in the world.

Even any two people will have different thoughts and ideas.

Even the same person may have different thoughts from one second to the next.

A single person is chaotic and changeable, so it is even more impossible for a large number of people to be of one mind.

But the amazing thing is that there is always a faint and consistent thought in everyone's heart, and those thoughts that come from the heart are always in line with the will of heaven.

The hearts of the people are the direct reflection of Heaven’s will.

Therefore, human hearts hate killing, hate chaos, and hate abnormal deaths, which means that the will of heaven is the same.

But war is an exception.

Because, my hero is his enemy.

As long as the killing is confined to the battlefield and the target is the main participants in the battle, Tianxin will not despise the killer.

A few minutes passed, and the body of Uchiha Yuuki's clone collapsed, and the ninjutsu ended completely.

As the ninjutsu ended, the big tree stopped moving and turned into a real big tree. The sound of the waves in the sea of ​​trees also subsided, and the battlefield fell into absolute calm.

This is true silence.

There are no animals in the newly born forest yet, and the absolute silence without the chirping of insects or birds does not make people feel quiet, but only scary and eerie.

But this feeling of horror soon disappeared from the hearts of the Konoha ninjas.

This is the Wood Release of our Konoha Village, this is the ninjutsu performed by our companions, and it is our miracle!

Why should you be afraid?

Suddenly, a young Snake Ninja on the right side shouted, "This is Wood Release! Long live Wood Release! Long live Konoha Village!"

The cheers spread quickly and reached the entire battlefield in a very short time. The cheers of the Konoha ninjas resounded through the sky.

Seeing the huge forest created by Wood Release, even the dullest Konoha ninja realized that victory was coming.

No ninja village can resist such ninjutsu, and victory has already belonged to Konoha Village.

The war has entered its third year.

For most of the Konoha ninjas, they did not have the opportunity to return to the village to rest like Uchiha You. Unless they were seriously injured or disabled, they had to stay on the front line.

Their longing for peace and their families had already accumulated to the extreme, and all turned into a desire for victory.

How can you not go crazy when you see the hope of victory?

…

The land of grass.

Uchiha Madara's excitement only lasted for a few seconds before he realized something was wrong.

Uchiha You was pierced by dozens of black thorns of various sizes, but not a drop of blood came out. This is impossible.

Realizing that something was wrong, Black Zetsu instantly broke away and rushed towards the shadow under Uchiha Madara's feet.

During this process, a hand stretched out from the injured Uchiha Yu and grabbed the Black Zetsu in the air.

Uchiha Madara also jumped back far away with a serious expression.

In the battle just now where he was 1 against 15 wood clones, Uchiha You fully demonstrated his strength in close combat, which is definitely not something that the current Uchiha Madara can deal with.

If he were entangled with Uchiha Yu, Uchiha Madara might be killed instantly.

Uchiha You did not pursue. He looked at his empty hands and said regretfully: "I really can't touch it."

"I never thought that the principle of being invincible due to the gap between two classes would actually work in the ninja world."

"It seems that one must have the power of the Six Paths level to come into contact with the products of the Bloodline Network."

Uchiha Madara widened his eyes and asked, "What is the Bloodline Network? What is the product of the Bloodline Network?"

Uchiha You smiled slightly and replied: "The Bloodline Net is above the Bloodline Limit and Bloodline Elimination. It is a super power formed by the seven types of chakras, fire, wind, earth, water, lightning, yin and yang, which have undergone changes in nature and perfect fusion."

He raised a finger and continued, "There's only one word I can think of to describe the Bloodline Network, and that's 'invincible'."

"As for the product of the bloodline network..."

Uchiha You looked at the nervous Uchiha Madara, suddenly smiled and said: "I won't tell you!"

Uchiha Madara's whole body shook. He lowered his head and saw a bloody hand extending from his chest, and in that hand was holding a beating heart.

He raised his head and looked at Uchiha You in front of him, and Uchiha You who was full of black thorns, all turned into wooden textures.

Uchiha Madara said with difficulty: "They are all wooden clones. When did it happen?"

Uchiha You behind him said: "My ancestor of Yuchun, in this ninja world where even death cannot keep secrets, it is better for you to be a confused ghost."

Then, he used his five fingers to crush the heart that had left the body but was still beating.
