While Kirito is tirelessly improving his strength and sorting out his combat system, his two good teammates, Chizuru Uchiha and Senju Rope, are also working hard to improve their strength.

As ninjas who have reached their strength at a young age, the two of them have long lacked their heritage, and what they lack is the opportunity to fully tap this heritage, which is also a hard actual battle.

On the battlefield, there is nothing like actual combat to quickly improve the strength of a ninja, as long as you don't die, there will always be something to gain.

Chizuru and Rope Tree were undoubtedly stimulated by Kirito's strong strength, and in order to quickly improve their strength, both of them decisively chose to start a life-and-death battle with the enemy.

Seven or eight kilometers away from the Shata where Kirito is located, there is a small oasis, which is a war camp in Konoha deep into the Land of Wind, and after the transformation of some Konoha ninjas who are good at earth escape, a small earth city has appeared here.

The most conspicuous building in the earthen castle is a gladiatorial arena made entirely of sand.

This gladiatorial arena was built by Kirito with the ability of Moritsuru to handle sand, and the construction process used the ninjutsu of the sand binding machine, which uses a huge pressure to compress the sand together, and finally forms a solid gladiatorial arena.

This gladiatorial arena is a place where Kiritto specially uses to improve the strength of the Konoha ninjas on the battlefield.

Here, they can take on some powerful sand ninja captives.

In the past few days, Kirito has not done nothing, he has relied on his strong strength to single-handedly rush into the camp of Sha Yin many times and wreak havoc, forcing the people of Sha Yin to take the initiative to abandon the camp and retreat.

And in the process, Kirito easily captured some ninjas with good strength.

These ninjas are all shinobi without exception.

Kiritto didn't kill these Sand Hidden Ninja, of course, not because he was soft-hearted, but simply wanted to use these Sand Hidden Ninja to practice some Konoha ninjas who were optimistic about him.

There are no restrictions on the captives in the gladiatorial arena except for the curse mark planted in their bodies, and Kirito also has the medical ninja heal their injuries and give them weapons to take advantage of, so that these captive ninjas can fight in the gladiatorial arena in the best condition.

At the same time, in order to motivate these captive ninjas to fight, Kirito gave them a promise to set them free as long as they achieved ten victories, and also told them that they could kill.

As for whether the Konoha ninja is willing to risk their lives to fight in the gladiatorial arena, it is all voluntary.

If you want to use actual combat to improve your strength, how can you not take risks?

Kirito became a shadow-level powerhouse at the age of 11, and the news of killing Ebizo and capturing Ichio not only greatly boosted the hearts of the Konoha ninjas, but also seriously stimulated their competitive spirit.

Therefore, it is not only Chizuru and Rope who are keen to enter the gladiatorial arena to fight these captive ninjas with the strength of the upper ninja, but also many young Konoha ninjas.

For example, Hinata Hanari and Bo Feng Shuimen, the two are also the nearest regulars in the gladiatorial arena.

Sand Xing, who is over forty years old, is a veteran puppeteer in Shayin, although his strength does not reach the elite upper ninja, but he is also the best among ordinary upper ninjas.

In fact, the reason why he was not able to reach the elite level of ninja was that he did not have enough wealth to build an excellent puppet.

If he can have a ninja-level puppet in his hand, he can control two puppets at the same time to use ninjutsu combat ability, and the strength of the elite ninja is not enough.

It's a pity that he was born in a civilian family, and he was able to stand out among many Sand Hidden civilian ninjas, learn excellent puppet techniques, and successfully build three elite mid-ninja level puppets on his own, and finally become a ninja-level puppeteer, which is already very remarkable.

In this war between Sand Hide and Konoha , he made a lot of contributions to Sand Hide, and the Konoha Shinobu and Shimoshinobi who were killed by him with a puppet are no longer rememberable, but he always remembers that there are three Konoha Shinobi who died in his hands.

Now, the Konoha imp in front of him, who has the strength to endure at a young age, will be the fourth.

He remembered the name of this Konoha imp, a person from the Uchiha clan of the Konoha clan, called Uchiha Chizuru, and the other party was the teammate of the devil named Kirito Tosaka.

As a person with the blood of Konoha ninjas on his hands, Sand Hoshi certainly didn't think that the devil would really keep his promise, and his only thought now was to kill a few more Konoha ninjas and pull a few more backs before being silently executed by the devil.

"Little ghost, for the devil's sake, if you don't want to die, you'd better surrender immediately."

Before the battle, Sand Star looked at the Uchiha Chizuru who was staring at him coldly in front of him, subconsciously staggered with the other party's eyes, and said coldly.

If he could, he would love to kill a few more Konoha ninjas.

It's a pity that his first opponent after being captured was this Konoha imp named Uchiha Chizuru, and once he succeeded in killing this Konoha imp, he would definitely not survive.

As soon as the words fell, he quietly connected the two puppets around him with chakra wires, letting them protect him one left and one right, and then a strong self-confidence surged in his heart.

He dared to threaten an Uchiha Shinobi so confidently, not because he knew that he was going to die, but because of the two puppets around him.

These two puppets were lent to him by the devil, and they were both ninja-level puppets.

It can only be said that they are puppets created by the devil, although these two puppets are obviously inferior to the two puppets used by the devil on the battlefield, but they are still rare boutique puppets.

It was the first time for him to use such a high-level puppet, and he didn't expect the devil to lend such a good puppet to him as a captive to use.

Life is wonderful.

Before he was captured, his greatest wish was to have a ninja-level puppet, but after being captured, this wish was easily achieved.

As a puppeteer, he can clearly feel the gap between his original puppet and these two puppets, and the biggest gap is undoubtedly Chakra's conductivity.

Compared to the two golems that clearly used chakra metal inside, the two golems he had built before were nothing short of a pile of garbage.

After he used the chakra line to control the two puppets, he immediately found that his chakra could pass very smoothly through the artificial chakra meridians inside the two puppets, which greatly reduced the chakra consumption of the puppets he controlled, and allowed him to control the puppets more easily and delicately.

In addition, it is the physical strength of these two puppets that is very good, comparable to the physical ninja of the upper ninja level.

Because of this, they can easily withstand his chakra output of various frequencies, so as to burst out with speed and strength no less than the upper ninja level, and with full burst, they can even reach the speed and strength of the elite upper ninja level in a short period of time.

With these two puppets, Sand Star can confidently say that he is now a veritable elite upper ninja level puppeteer.

When Chizuru heard Sand Star's warning, she was completely indifferent, and silently put her hand on the hilt of the famous sword Thunder Light Fierce Fight on her waist, and then opened the Sharingan.

Sha Xing had already seen Chizuru's movements through the mechanical eyes on the puppet's body, and knew that this Uchiha ninja would not back down, and his heart suddenly gave birth to a thick killing intention.

At the same time, he couldn't help but marvel at the two puppets he was now controlling.

The mechanical eyes installed on these two puppets are really fantastic, not only does he not need to use the third eye arcane technique to directly look at the Uchiha ninja's writing wheel eye without using his eyes, but it also has the function of zooming in and out, allowing him to clearly notice his opponent's movements from a distance.

"Damn, this devil is really rich."

Sand Star was jealous of this, and his heart deepened the idea of using the devil's puppet to kill the devil's companions.

The next moment, a blue-white electric light appeared in the field of vision of the sand star.

He knew it was his opponent's shot.

But he didn't panic, his left index finger moved, and a mechanism instantly popped out of the chest of a puppet on the left, and a blue chakra shield instantly protected him and the puppet.

"Keng~"

A long sword covered in Thunder Chakra slashed at the shield behind Sand Star.

"Little girl, your strength is good, but it is impossible for you to break through the defense of my puppet technique and machine light shield seal, if you want to blame it, the puppet that your companion gave me is too good."

Sand Star sneered when he saw that Chakra's shield easily blocked Chizuru's sneak attack.

As he spoke, the other puppet he controlled had already burst out with a speed comparable to that of an elite shinobi using all his strength to rush to Chizuru, and slammed his fist covered with chakra at Chizuru's head.

In order to successfully kill Chizuru, Sand Star did not hesitate to carry out the maximum frequency of chakra output to the puppet as soon as he came up, so that it could become a powerful elite ninja level physical ninja in a short period of time.

Chizuru didn't expect that the puppet that Kirito handed over to the captive Sand Shinobi could burst out at such an astonishing speed, and she suddenly opened her eyes slightly, and instantly smelled the breath of death.

But that's exactly what she wants.

Looking at the fist that was approaching quickly, she subconsciously injected the curse mark chakra in her body into her writing wheel eye, causing the three magatama in the writing wheel eye to rotate rapidly and connect together.

In an instant, she noticed that the fist of the puppet in front of her had slowed down.

Chizuru is very smart, since she discovered that the curse mark can fuse chakra with natural energy to form a spell mark chakra that can strengthen ninjutsu, she secretly went to look through some of the family's books related to natural energy, and then understood that these spell marks formed by the spell mark chakra are immortal chakra.

At the same time, she finally understands that the chakra that Kirito injected into her spell mark is the fairy chakra, and she also discovers that Kirito's fairy chakra is obviously much higher in quality than the fairy chakra she formed with the spell mark.

In this regard, of course, she is unwilling, and wants to make her immortal chakra quality catch up with Kirito's immortal chakra.

For this reason, Chizuru began to continue to study the curse mark chakra, and after nearly a year of hard work, although she was not able to successfully create the fairy chakra on her own, she found out that she could use the spell mark to create the spell mark chakra without opening the spell mark.

Moreover, she also found that the Sharingan would continue to be strengthened under the long-term nourishment of the Curse Seal Chakra.

This enhancement is not only reflected in the pupil strength, but also in the observation ability of the writing wheel.

If you use the Chakra to open the Sharingan, the Sharingan will also be temporarily strengthened.

Like now.

She was temporarily strengthened by a large number of curse seal chakras, and she was confident that her dynamic vision of her chakra was not white at all, and even surpassed that of ordinary white-eyed ninjas of the upper ninja level.

The enemy's movements have already been seen through by her.

Next, all she needs is to improve her nervous reflexes and movement speed.

Spell: Thunder Thrill!

Black lightning suddenly appeared on Chizuru.

Sand Star's puppet finally punched Chizuru on the afterimage left in place.

"So fast!"

Seeing this, Sha Xing was shocked in his heart, and finally realized that Chizuru's strength was even stronger than he imagined.

Before he could react, the puppet he controlled was circled by a thousand cranes that seemed to turn into a black lightning bolt, and then the head and limbs were all cut off and directly scrapped.

Sword Skill: Thunderbolt!

"That's it?"

Chizuru stepped on the puppet's body, staring at the sand star who was swallowing saliva in the chakra shield at this time, and said disdainfully.

The puppet is the embodiment of the puppeteer's strength, and the loss of a ninja-level puppet in Sand Star is equivalent to cutting off an arm.

Soon, Sand Star was hit by a black, high-temperature fireball and burned to ashes.

Spells, Fire Escapes, and Howe Fireball Techniques!

"It's too weak."

Chizuru looked at the ashes on the ground in front of him and said dissatisfied.

Then, her eyes looked at a blonde boy on the viewing platform, with a defiant look in her eyes.

The blonde boy is Bo Feng Shuimen, and now that he is being looked at like this by Chizuru, he can't help but have a strong fighting spirit in his heart.

He had just seen the whole battle between Chizuru and Sand Star, and knew that this girl from the Uchiha clan who was on the same team as Kirito's monster was also a monster, but the monster level was not as big as Kirito's.

But judging from the battle just now, Uchiha Chizuru's strength has surpassed that of ordinary elites and shinobi a lot.

"It's so fast, and the reaction is also very fast, I don't know if my Flying Thunder God Technique can successfully sneak up on her."

Bo Feng Shuimen muttered to himself in his heart.

Just as he was about to stand up and accept Chizuru's invitation to fight, Hua Ren beside him stood up, and then without waiting for him to speak, Hua Ren quickly formed a seal, using the technique of water instantaneousness, and instantly appeared on the battlefield of the gladiatorial arena.

"Uchiha Chizuru, I, Hinata, want to challenge you."

Hua Ren looked at Chizuru with a dissatisfied expression on her face in front of her, took a deep breath, and then put on a soft fist starting gesture and said solemnly.

As soon as the words fell, she opened her eyes, and at the same time, a large number of flame-like spells appeared on Hua Lian's body, causing her aura to rise steadily, and the appearance of her whole person was also changing rapidly.

"I accept your challenge."

When Chizuru saw this familiar scene, a deep murderous intent suddenly erupted in his eyes, and he said coldly.
