In the thirty-second year of Konoha, war broke out.

The ninja world has been peaceful for more than ten years, and every country and every ninja village is developing.

However, the land of the country of wind and the country of earth is barren, the resources are scarce, and the economic development is slow, so we can only watch the country of thunder, the country of fire and the country of water become stronger step by step.

At this time, the two brothers were reluctant and directly asked each other country to give them a little territory, otherwise they would invade and expand their territory by force.

The three kingdoms of fire, thunder, and water all ignored them, and the leader of the Land of Rain, known as the "demigod" Sanshoyu Hanzo, was dissatisfied with the environment of the Land of Rain and wanted to expand his country's territory, and war was on the verge of breaking out.

First of all, the country of wind, the country of earth, and the country of fire declared war, and the two major ninja villages directly sent troops to the country of fire.

The two countries want to use the Land of Rain as a battlefield to fight Konoha.

Not to be outdone, Konoha entered a state of war, directly gathered an army of ninjas, and marched towards the Land of Rain.

In the course of the war between the three great powers, Sanshoyu Hanzo took this opportunity to invade the Land of Iron and officially opened the prelude to the Second Shinobi War.

As the war heats up, Hanzo's ambitions grow, and he aspires to become the sixth great nation in the ninja world.

So, on behalf of the Land of Rain, he declared war on the Land of Fire, the Land of Wind, and the Land of Earth at the same time.

Although the ninjas in the Land of Rain are all weak chickens, Hanzo was able to release a large amount of biochemical poison gas, resulting in heavy casualties among the ninjas in the three villages.

For a time, Hanzo single-handedly suppressed the three major ninja villages, and the name of "demigod" also spread to the ninja world.

At the same time, Tsunade, Jiraiya, and Orochimaru are also sent to the Land of Rain to fight in the war.

Although the war broke out and the village went into a state of alert, Natsu and Kushina were not affected in any way.

For ninja school students, it is still necessary to go to school as usual.

Nothing has changed in school life, except that some students, stimulated by the war, want to graduate early.

Yu Furukawa came in from outside the classroom and began the lesson.

For someone like Xia Wu, who had already been able to graduate from self-study, the ninja school curriculum had long been meaningless.

He pondered the question of natural energy.

It's been a month since he entered the Wet Bone Forest and knew how to absorb the energy of nature.

In the past month, he has absorbed natural energy every day to warm his body, and every inch of flesh and blood in his body has absorbed natural energy, and his body has undergone another transformation.

However, he found that the natural energy was too violent and unstable, and it was much more difficult to manipulate the natural energy than the chakra.

Xia Wu can be easily controlled because his soul is strong, and it is still difficult for others to do it.

And how to use natural energy to release ninjutsu is also a question.

If there is no means to do so, the natural energy will soon overflow and disappear and return to heaven and earth.

At present, Xia Wu's idea is to fuse the natural energy and the qi and blood in the body and turn it into a seed.

The seeds can absorb the energy of heaven and earth and transform it into true qi, and then create meridians within the body.

In this way, the true qi will not dissipate on the spot even if it leaves the body.

Moreover, the operation of true qi is also washing the body, which can promote the transformation of the body.

It can not only enhance the physical body, but also cast spells in place of chakra.

And it's even more powerful, it's so much easier to use than a chakra!

As for the cultivation above the qi veins, Xia Wu didn't have time to deduce it for the time being.

Time passed quietly.

Except for Konoha Hospital, Konoha has not changed much, just a little deserted.

Many seriously injured patients have returned from the battlefield one after another, and Konoha Hospital is very busy every day, and even Xia Wu has been assigned several treatment tasks.

The battle in the Land of Rain is extremely fierce, and the situation is changing rapidly.

After several months of fierce fighting, just as the main force of Iwakure was fighting with the troops of Yuyin Village led by Hanzo, the three generations of Thunder Shadow suddenly poured out the power of Yunyin Village and led an army of tens of thousands of ninjas to attack the territory of the Land of Earth.

The main force of Iwakuin in the Land of Rain immediately returned to defense, but when the follow-up troops retreated, they were severely damaged by the troops of Yuyin Village led by Hanzo.

And the war between Konoha and Sand Hide has also entered a white heat, originally both sides thought that Iwakure would be able to hold off Hanzo, but they didn't expect the three generations of Thunder Shadow to sneak attack Iwa Shinobi, causing Hanzo to free up his hand.

Just as Konoha and Sand Shinobi were fighting hotly, Hanzo suddenly led his army into the battlefield.

The poisonous gas of the Sansho Fish was released, and the ninjas of the Land of Fire and the Land of Wind were almost killed and wounded.

Only Tsunade, Orochimaru, and Jiraiya survived.

But Hanzo did not kill the three, but was given the title of "Three Shinobi".

Tsunade, Orochimaru, and Jiraiya have also been known in the ninja world since then.

Although he failed to defeat Hanzo, Konoha was better than Yuyin Village in terms of overall strength, and Yugakure also faced two strong opponents, the Land of Wind and the Land of Earth.

In the end, the two countries signed an armistice with Konoha winning, and the Konoha ninja withdrew from the battlefield of the Land of Rain.

In the process of the evacuation of the Konoha ninja one after another, the three ninjas also met the leaders of the largest terrorist organization in the future ninja world, three orphans, Nagato, Yahiko, and Konan.

Out of regret and pity, Jiraiya decided to leave them alone to take care of them and teach them.

Tsunade and Orochimaru led the troops back to Konoha, and the villagers all went to the gate to greet the triumphant team.

However, Xia Wu did not go.

"Xia Wu, Sister Tsunade is back, aren't you going to greet you at the entrance of the village?"

Jiu Sinai came to Xia Wu's house and wanted to call Xia Wu to go with her.

"No, my parents have died a long time ago, and this kind of thing doesn't matter to me at all."

Xia Wu replied calmly.

"By the way, Xia Wu, I don't know about your parents yet?"

"But they're just ordinary ninjas, there's nothing to say."

After Xia Wu finished speaking, he continued to practice.

All his thoughts now are on martial arts cultivation.

He had successfully fused natural energy and qi and blood to form a true qi seed.

Then there is the condensation of meridians, and it just so happens that in his previous life, Xia Wu had understood the large and small meridians in the human body.

To condense all the meridians is a big project that takes a long time.

But ordinary people don't need to be so complicated.

Seeing Xia Wu immersed in cultivation again, Jiu Sinai also stepped aside to practice turtle and snake fist.

She sighed in her heart, feeling that the gap between herself and Xia Wu was getting bigger and bigger.

Kushina came to the sealing space and shouted at the Nine-Tails:

"Nine-Tails, how are you thinking about it?"

Nine-Tails said impatiently:

"Stinky little ghost, you have to ask several times a day, you're so annoying!"

Then it closed its eyes and ignored Kushina.

"Kushina, don't be distracted."

At this moment, Xia Wu's voice sounded in Jiu Xinnai's ears.

As soon as she turned around, she saw Xia Wu standing behind her.

Jiu Sinai exclaimed: "That, I ....."

Xia Wu said softly:

"Don't worry, Jiu Sinai, with your talent, you will soon catch up with me, martial arts such a thing, the more impatient you are, the slower its entry will be, just let it be."

"yes, I see."
