I practice martial arts in Konoha

seven days later.

"Master Neji, I have brought you the things you ordered at the ninja shop."

Tatsuya handed over a sealing scroll.

The white clone didn't pick it up.

"Open it!"

Tatsuya followed the orders.

"How is Tenten's training in nintaijutsu?"

"The body-tempering secret medicine provided by Neji-sama is very effective. Miss Tiantian has learned the moves of the Five-Shaped Fist and found some feelings in the Crane-shaped Fist. I asked her to concentrate on practicing the Crane-shaped Fist for a while in the future. Observe the posture of the crane and try to understand the shape and meaning of the crane..."

Tatsuya said, forming seals with his hands and pressing them on the seal scroll.

boom!

The smoke dissipated.

There is a large iron pot on the ground.

There was more than half a pot of black iron sand inside.

The white clone grabbed a handful of iron sand and rubbed it a few times.

The iron sand is only the size of sesame seeds, with plump and rounded grains. It feels heavy to the touch, with softness in the hardness and hardness in the softness, making it hard to put it down.

"Old Chunguang's craftsmanship is pretty good..."

The white clone stretched out his hand and slapped it on the ground, causing earth escape chakra to flow out.

The soil under the iron pot rose rapidly and solidified into a rock column more than one meter high, firmly fixing the iron pot at the top.

"Lord Neji, what are you doing?"

Tatsuya expressed his confusion.

White clone: ​​"Tatsuya, I said before that I want you to be my experimental assistant... Next, we will start the first experiment."

Tatsuya: "What about the five-shaped fist from before?"

"The Five-Shaped Fist is only used to quickly improve your control over your body, mind and chakra, allowing you to reach the minimum standard of the experiment in a short period of time."

"Didn't you find that your abilities have been improved in all aspects?"

"The amount of chakra has been greatly increased, and the Earth Release Ninjutsu that was impossible to practice before can now be used easily."

"The practice of Five-Shaped Quan cannot be accomplished overnight. It must be practiced over many years and with perseverance. You can leave it to practice slowly in the future."

"In these days, you have to focus all your energy on our first experiment."

The white clone said, taking out a test tube and throwing it to Tatsuya.

"Apply the potion evenly on both hands!"

Tatsuya took a look and saw that the medicine in the test tube was light blue, as charming as embodied chakra, with dots of green light emerging from inside.

"Isn't this the body-tempering potion you gave me and Miss Tiantian before?"

"Yes, but the body tempering potion I gave you before was diluted, and the concentration of this one is ten times higher than that one. The quantity is scarce, so you must use it sparingly."

Of course the white clone wouldn't say it. In fact, this one is also diluted, but the degree of dilution is different.

Tatsuya nodded, carefully poured out one-tenth of the amount from the test tube, and barely spread it evenly on his hands.

Under the icy cool feeling, a warm energy slowly penetrates into the skin.

The hands seemed to come alive all of a sudden, every cell greedily absorbing this energy.

"Quick, use fire escape to heat up the iron sand in the pot!"

After hearing the command from the white clone, Tatsuya did not hesitate, quickly formed a seal, opened his mouth and sprayed a large fireball into the pot.

boom!

The flames dissipated.

The iron sand was burned until it shone slightly, and the heat filled the air.

Seeing this, Tatsuya prepared to spit another fireball.

"enough!"

The white clone stopped in time.

“It doesn’t have to be too hot at first!”

"You first apply a thin layer of earth attribute chakra evenly on your palms, and then maintain this state, put your hands into the iron sand, and rub every centimeter of skin on your hands with the hot iron sand!"

When Tatsuya heard such a perverted request, he almost broke into a cold sweat when he thought about his stupid move of adding another fireball just now.

Even now, the temperature of the iron sand is three to five hundred degrees.

It's definitely not something a pair of fleshy palms can bear!

There was a hint of fear in Tatsuya's eyes.

"Do it soon!"

"Yes!"

Tatsuya responded loudly.

Take a deep breath and let go of your fears and distracting thoughts.

Release the chakra from your hands to change the earth attribute, and then rub your hands together like rubbing mud, kneading the earth attribute chakra evenly on your palms.

Waited for a while.

He felt that he could output chakra at a constant speed for a long time and maintain the stability of the earth attribute changes, so he slowly extended his palm into the hot iron sand.

laugh!

Tatsuya bared his teeth for a moment.

The iron sand at three to five hundred degrees was so hot that even with the protection of earth chakra, his palms were burned immediately.

Tatsuya ignored it and endured the severe pain. He grabbed the hot iron sand and rubbed it against each other.

in a blink.

He was sweating profusely and falling down.

I don't know if it's hot or painful.

at this time.

The potion applied previously began to take effect.

That warm energy keeps emerging, and the injured cells are repaired, injured again, and repaired again...

In this process of repeated burns and repeated healing, the heat resistance of cell tissues increases little by little.

"You have to forget the pain, or even the existence of your hands, and imagine that your hands are two red-hot irons. Every time they are rubbed, a stream of sparks can be generated..."

"Yes, Neji-sama!"

Tatsuya shouted loudly.

The white clone nodded slightly. Tatsuya's qualifications were not very good. He was only considered to be at an upper-middle level. He was more successful because of his perseverance, perseverance, willingness to obey orders and endure hardships.

In fact, this experiment.

His initial idea was that Tatsuya would output fire attribute chakra with one hand and earth attribute chakra with the other.

The chakra of fire and earth comes from the same root.

Through the medium of iron sand, they collide with each other and stimulate each other.

The various effects produced by collisions and stimulation will be fed back to his hands, inducing wonderful changes in the cells of his hands.

However, it was too difficult for Tatsuya to control chakra to change two properties at the same time.

There's no way he could do it.

So the white clone changed the plan and went to a ninja tool shop to order special iron sand containing a trace amount of fire-attribute chakra metal.

Tatsuya first used Fire Release to burn the iron sand.

The iron sand will not only absorb and preserve heat, but the chakra metal in the iron sand will also absorb and preserve his fire attribute chakra.

Tatsuya then used the earth attribute chakra to attach to his hand and touch the iron sand, which also allowed the chakra of the two attributes to merge into one furnace to achieve the same effect.

It's just that Tatsuya has to work hard. Every few minutes, he has to spray fireballs to heat the iron sand.

after an hour.

Tatsuya was sweating profusely, and his hands had lost all feeling. Just when he was about to be cooked, the white clone finally announced the end.

"For the next period of time, you should take a long vacation and do not go on missions again. Other training such as five-shaped boxing and ninjutsu will also be temporarily suspended."

The white clone carefully examined Tatsuya's hands, applied medicine to him again, and wrapped a medical bandage on him.

"Our teams have planned to conduct special training these days to prepare for the Chunin Exams in a month's time."

"The Chunin Examination will be held in one month..."

The white clone rolled his eyes and seemed to have another idea.

Tatsuya hesitated and asked, "Ningji-sama, is our experiment developing a new ninjutsu?"

"Yes and no."

"what?"

"The specific technique depends on the final results of your practice."

"Then what's the name of this technique?"

"The name of this technique is..."
