Naruto's strongest doctor

A large amount of chakra surged in Tōsen's body, like a surging sea, beating Tōsen's blood.

The subtle changes brought about by the earth attribute ninjutsu one after another were undetectable to Dongxian before, but the accumulation of countless quantitative changes in his body will cause the final qualitative change!

rumbling...

Standing up, Dongxian's jet-black broken hair moved without wind, completely blending into the night behind him.

The aura of the whole person is undisturbed, full of explosive power, and the uninterrupted practice before has brought Dongxian not only the refinement of the art of different veins, but also the advancement of his level.

Clenching fists with both hands, feeling the chakra in the body become more and more full, and the number has increased a lot. Taking a deep breath, Dongxian's eyes flashed, "A second-level ninja!"

"call……"

Slowly controlling the momentum of the whole body, the Chakra between heaven and earth rushed towards Dongxian's body quickly, filling the space in his body that had been expanded due to advancement.

Raising his hand slowly, there was nothing in Dongxian's wide and white palm.

However, if someone can take a closer look, they will find that in his palm, there are actually extremely small black particles, whirling and circling, like dust and sand.

"This is... the embryonic form of me, Blood Successor Boundary...?"

Squinting his eyes slightly, Dongxian looked at the black particles in his hand, which were the acquired blood inheritance boundary created by him with the help of the different vein technique.

It is actually not accurate to say that it is the limit of blood inheritance, because this is just the beginning, and it may not even be considered the real prototype.

However, Dongxian was excited at the moment, looking at the black particles flying in the palm of his hand, this at least proved that the art of divergent veins is not a dead end, perhaps, the acquired blood successor boundary can really be realized!

"Come again..."

The whole person's spirit was greatly lifted, and Dongxian's chakra flowed rapidly, and he was once again devoted to the selfless earth escape practice.

Repeatedly practiced all the newly learned earth attribute ninjutsu dozens of times, and when Dongxian spread his palm again, the black particles that had never been seen had swelled a lot, and the number also increased.

Looking from a distance, one could already vaguely see a cloud of faint black mist in Dongxian's palm.

This is what Dongxian created by practicing earth attribute ninjutsu with the help of different veins.

"Black grains of dirt...but harder...sharper..."

With a shake of his left foot, Dongxian's body turned [-] degrees on the spot, and he slapped out with a palm without using any force, and it hit the trunk of a big tree next to him accurately.

"Crackling..."

The palm hit the tree trunk without much force, but the sawdust splashed and produced a friction sound, which was the additional effect produced by the whirling cutting of the black particles.

Quickly withdrew his hands, and glanced at the attacking position, Dongxian's pupils shrank, and a palm print was clearly visible, and it sank into the tree trunk shallowly!

His face was filled with joy, and seeing the black mist circling in the palm of his hand, Dong Xian's eyes were bright, "Is it hard and sharp black soil...then I will call you, Hei Jin!"

Black gold, the mutated soil initially produced by Dongxian's practice of divergent veins, has a hardness beyond that of rocks, and at the same time, it has extra sharpness due to its extremely small size.

With five fingers bent and fists clenched tightly, Dongxian took a deep breath, suppressing the uncontrollable joy in his heart, "My... the day after tomorrow... Blood Successor Boundary!"

Knees bent, and then exerted a sudden force, Dongxian's figure swayed, and he galloped forward at an extremely fast speed, turning into an afterimage, rushing towards the root.

……

In the training ground, the boy and the [-]th-rank ninja were trembling and fiercely fighting.

The ninth-level ninja tried his best to deal with the opponent's swift and fierce attack.Without using the slightest ninjutsu, the opponent just held a kunai, which forced him to retreat a bit.

The boy was very familiar with using kunai, and from the eyesight of the ninth-level ninja, it was very similar to Konoha Anbe's usual technique, but more importantly, the boy's kunai was extremely hard and sharp.

"Ding ding ding..."

Holding the ninja knife and colliding with the opponent continuously, there are many gaps in the original white blade.

"It's not enough... come again!"

As if dissatisfied, the boy shouted at the ninth-level ninja.The latter's eyes grew angry, when had he ever been underestimated by a second-order brat?

Immediately, he jumped back a few steps, opened the distance, formed seals with both hands, and performed a fire escape ninjutsu.

However, the boy on the other side still only used a kunai, and unexpectedly cut through a fireball, and came close to him again.

"hateful……"

Gritting his teeth secretly, the ninth-level ninja looked solemn and could not use high-level ninjutsu. It was really difficult to defeat the young man in front of him, and a trace of panic finally began to show on his face.

Around the training ground, a group of ninjas huddled together, watching the boy's increasingly proficient and swift skills, looking at each other in blank dismay.Let the ninth-level ninja act as a training partner for the second-level ninja?No matter who it is, it is too extravagant.

However, the young man in the field did it, not for any reason, just because he had the Fuxue Pill and the capital to make the ninth-level ninja willing to practice with him.

It didn't take long for the battle in the training ground to end when the ninth-level ninja's ninja broke.

Grinning at the other party, Dongxian threw a blood recovery pill at him, then turned his head and shouted, "Who's coming next?"

Everyone glanced away, and before they could speak, they were preempted by a second-rank ninja.

"I come……"

In the training ground, the sound of fierce fighting broke out again.Relying on the allure of Fuxuewan, Dongxian openly recruited ninjas as his training objects in this root headquarters.

This kind of treatment, I am afraid that even the big families like Hinata and Uchiha, few people can bear it.

In the arena, Dongxian held a kunai and attacked fiercely.Time was running out, and one person would not achieve much by working behind closed doors, so he chose to go to the roots and hone himself in real combat.

Although the opponent's level is extremely high, if the use of high-level ninjutsu is restricted, Dongxian will have to fight.

At present, Dongxian can only convert very little soil into black gold, and the black gold can't be too far away from his body, almost only a few fingers wide.

It is Dongsen's unique idea to cover black gold on Kunai, so that he can not only practice his precise control over it, but also improve the hardness and sharpness of Kunai's own material.

"Next!"

"It's been replaced!"

"Who wants to come?!"

……

Tireless, the young man in the training ground, like a complete fighting machine, actually replaced five training partners in a row, and the highest one even reached the fifth rank of ninja!

"boom!"

The chakra fluctuated all over his body, and Dongxian was overjoyed, and whispered: "Okay! Advance again!"

At this moment, a root ninja suddenly moved quickly from the passage, flashed to Dongsen's side in an instant, and whispered: "Master Hokage is calling for you! Please go quickly!"

With a raised eyebrow, Dongxian's mind moved slightly, and he threw the last blood recovery pill to the opponent, and then rushed towards Hokage's office without stopping.

"Is it finally time to reveal the answer?"

The reasons for Jiu Liyu's serious illness and the unusual final exam will all be revealed in the summoning of Hokage.

With his body shaking, Dongxian's speed suddenly increased, and he turned into an afterimage and left!
