"You should just stay and develop new techniques for me. You are not an expert in this field at all."

"But once you leave, Lustful Immortal, there will be no one left to practice with me."

Naruto said without giving up.

"Well, that's true." Jiraiya thought for a moment, and then he thought of something and said to Naruto: "Wait for me here for a while."

After saying that, Jiraiya disappeared from the place.

About five minutes later, Jiraiya returned to his original position. Not only that, there was another person beside him.

"Nong, thick eyebrow teacher?"

Naruto was immediately surprised when he saw the person next to Jiraiya.

Wearing dark green tight-fitting clothes, Konoha's ninja forehead protector is tied around his waist, as well as the watermelon head that will make you care about it as long as you take a look at it, and the thick black eyebrows, it is Konoha's Jounin Matt

Kai.

"Naruto, good afternoon."

Kai greeted Naruto and subconsciously grinned, his white teeth shining.

"Jiraiya-sama has told me what happened. In the next few days, I will fight you one-on-one."

Kai continued to Naruto.

"Is Teacher Nongmei coming?"

There was hesitation on Naruto's face, as if he had a skeptical attitude.

As if he had seen through Naruto's inner thoughts, Jiraiya snorted and said: "Naruto, if you underestimate others too much, you will die. Although Kai's image is indeed a bit strange, but when he shows all his

In terms of strength, he may be the strongest ninja in Konoha. He is more than enough to be your opponent."

"Konoha...the strongest ninja?"

Naruto looked at Kai's thick black eyebrows, and his heart was still pounding.

The opponent didn't look like the strongest ninja in Konoha, and he didn't have the slightest bit of domineering power of a strong man.

"People should not be judged by their appearance. You still have a lot to learn. Now that the matter is settled, I still have things to be busy with."

Jiraiya didn't talk nonsense to Naruto. Before turning around and leaving, he quietly left a message in Kai's ear:

"It doesn't matter if you use the Eight Gate Dunjia. Let this kid suffer a lot and let him know what it means to have someone outside the world."

Kai was shocked. He thought it was just a relaxing sparring session, but he didn't expect Jirai to make these requests.

If he were allowed to use the Eight Gate Dunjia, it would not be a simple sparring exercise, but a real battle.

During the battle, it would be difficult for even him to control what would happen.

"I see."

Kai nodded seriously and took a very serious attitude.

Jiraiya patted Kai's shoulder, nodded, and left using the teleportation technique.

"Teacher Nongmei, let's start quickly."

Naruto couldn't wait to fight.

"There's no rush. I don't think there's much point in just fighting. Why don't we decide the lottery?"

Kai laughed.

"Luck?"

Naruto tilted his head and wondered what he meant.

Kai still smiled and said: "That's right. For example, the person who wins the battle can make a condition to the person who loses."

"Conditions? That's it. If that's the case, if I win, Teacher Nongmei, please treat me to Ichiraku Ramen and eat it to my heart's content."

Naruto's mouth drooled with appetite.

Kai nodded and did not refuse.

"Okay, but if I win, then, Naruto, you have to sprint a hundred times around the Leaf Village while standing on your head."

"..."

In late May, the weather was warm and pleasant, without the heat of summer.

The chill that blanketed the land of ghosts has long since dissipated, and the sun is shining everywhere, making it undoubtedly a perfect day for travel.

Located in the center of the huge sea of ​​trees in the northern part of the Kingdom of Ghosts, is a hollowed-out plain area of ​​more than ten kilometers.

Standing on top of the huge rock mountain, holding a military telescope, Ichiji could clearly see the rolling snow mountains in the north. That area belongs to the Snow Country. Like the Iron Country, it is a cold winter country with snow season all year round.

.

Then there was a buzzing sound in his ears, causing the earth to tremble.

Only then did Yi Ji move her gaze away from the snow-capped mountains in the distance, and instead turned to the huge plain area in front of her.

The rolling black steel is formed by armored artillery vehicles.

The flag engraved with aster flowers fluttered in the wind as the armored artillery vehicle began to run across the ground.

Next to each armored artillery vehicle, there will be three to five heavily armored ninjas from the Kingdom of Oni, marching forward together.

Compared to two years ago, the armored artillery vehicles were rolling faster. Even when encountering raised hills, they were running as if they were on flat ground, ready to launch an attack.

Opposite to the opposite side is a circular military fortress built.

From the fortress, flying ninja tools controlled by Ninja Shadow clones flew out, flying high in the sky, looking down at the earth from above, and the mechanical troops formed by hundreds of armored vehicles on the plains.

As bombs were thrown from the flying ninja tools and attacked the rolling steel on the ground, the ninjas from the Kingdom of Oni near the armored vehicle began to form seals, and as a group, chakra began to gather and condense.

A series of blue transparent walls covered the entire mechanical army, and an invisible shield wall was erected on top. After the reflection of the sunlight above the head, the blue transparent shield wall immediately emitted an illusive blue fluorescence.

boom!

The air-dropped bomb fell between the mechanical troops and made head-on contact with the blue shield wall.

The fire and shock waves generated by the explosion covered and surrounded everything in sight, and also dispersed the beautiful blue fluorescence.

As this life roared, more bombs were dropped from the sky again. Each detonation was like a heavy hammer, making the earth tremble and wail.

Among them, there are also flash bombs that block vision, poison gas bombs that can make a person incapacitated if inhaled, and incendiary bombs that turn the plains into a sea of ​​flames.

Then, a huge pit suddenly appeared in front of it. If the armored vehicle was not careful, it would fall directly into the pit, unable to climb out of the pit, and be buried deep underground.

Or build earthen walls around the armored vehicles to abruptly cut off the connections between them, thereby disrupting the offensive deployment of the mechanical troops.

Use various means to conduct indiscriminate attacks on the mechanical troops on the ground, and then impede their progress in various ways.

Even on the rocky mountain outside the battlefield, Ichiji could feel the strong hot wind coming from one side, blowing her long black hair and flying backwards.

Observed through military telescopes, this mechanical force was destroyed by nearly half before it reached the circular fortress where the 'target' was located.

Of the remaining half, many have reduced mobility.

The accompanying teams who used the protective barrier were also very tired.

Although the clothes they wore could withstand various extreme environments and had anti-virus effects, they still made them miserable and fell to the ground, greedily breathing air.

"We only lasted until the second round... The higher authorities asked us to persist until at least the third round. It seems there is still some way to go."

Yi Ji put down the military telescope. Although she was a little dissatisfied with the performance of the mechanical unit, she also knew that this could not be accomplished overnight.

"Let them clean up the battlefield quickly. It's the next batch of mechanical troops' turn to enter."

"yes."

The accompanying Jonin walked to the tent at the rear to notify the mechanical troops on the field to make changes.

As the next batch of mechanical troops entered the scene, they carried out dual attacks from the air and underground as before, constantly compressing the attack space of the mechanical troops in a tricky way.

A stream of hot wind blows from afar, making the place warm and pleasant, turning it into a summer-like heat.

Perhaps the local movement was too large, coupled with the excessive use of incendiary bombs, black clouds appeared in the upper levels of the sky, and the earth was shrouded in black shadow.

In the dark clouds, there were flashes of thunder, and fine raindrops began to fall on the sea of ​​trees.

Even so, the mechanical troops located on the plains did not stop training and persisted in carrying out this cruel exercise.

And this is just an exercise after all. Although the various ammunition dropped from the sky look bluffing, their power and attack frequency are deliberately reduced, and they are not fatal to ninjas.

"Lord Ichiji."

There was a voice coming from behind, and the messenger carrying a signal device came over.

"What's up?"

Yiji tilted her head slightly.

"Headquarters wants you to go back immediately with the members of the Thorn Team."

"now?"
