"Although I don't know why I feel so close to you like a family member, I feel good staying by your side, so I decided to accept your training and become a ninja." Ito Chengzai lowered his head and pondered for a moment. Finally, he looked up at the steel hand and said seriously.

"Okay." Steel Hand nodded slightly, turned to look at Shizune and said, "Shizune, start training him in basic physical skills from today."

"Yes, Lord Steelhand." Shizune agreed.

Afterwards, Gangtou returned to the room after finishing the matter, leaving Shizune to take Ito Cheng to the place where he practiced yesterday to train him in basic physical skills.

In this way, the day passed in the blink of an eye during training.

"Hey~" Back in the hotel, Shizune sighed helplessly after learning from the boss that Steel Hand had left the hotel again.

"Did Steelhand go gambling again?" Ito Cheng looked at Shizune and asked.

"Yes." Shizune sighed helplessly, and then said to Ito Cheng, "Okay, you go back and rest first, and I will go find Master Steelhand."

After saying that, Shizune walked out of the hotel and disappeared in the street under the yellow clouds in the sky. After Shizune left, Ito Cheng returned to the room and entered the Rubik's Cube world.

"I don't know how long the life of following the steel hand will last. During this period, there will definitely be few opportunities to enter the Rubik's Cube world. In this case, I'd better leave a shadow clone here." Standing in the house in the central area, Ito Cheng thought secretly.

Then Ito Cheng didn't see any movement, and then a figure who looked exactly like him suddenly walked out of a small cloud of smoke that dissipated after it appeared. Then Ito Cheng thought, and a small amount of rare world power suddenly fell from the void and entered the newly appeared Ito Cheng's body.

"This way, you don't have to worry about the shadow clone running out of energy and disappearing." After observing the energy status of the shadow clone's body with [Condensation], Ito Cheng nodded with satisfaction and said to himself.

Then Ito Cheng connected his thoughts with the Rubik's Cube and summoned the four resting people, including Karin, Uchiha Miko, Veretta and Kallen, to the house in the central area at the same time.

"Ito Cheng?" After Kallen's vision stabilized, she immediately shouted in surprise when she saw Ito Cheng. But just when she wanted to step forward, she suddenly found another figure standing next to Ito Cheng. Aki stopped hesitantly and looked at the two identical Ito Cheng with a confused expression.

"Acheng." After Kallen, Veretta also shouted happily, but she also showed a confused look after discovering the figure standing next to Itocheng.

"Sir," Uchiha Miko called next.

Kaoru, who did not say hello, looked at Kallen, Veretta and Uchiha Miko who appeared for the first time with a gossipy face. His eyes kept turning on the three of them and Ito Cheng. Of course, what she pays more attention to is the fact that Kallen's name is the same as hers. A girl with red hair.

Ito Cheng first smiled at Karen and Veretta and said hello, and then said to Uchiha Miko and Karin, "I have some things to do in the next period of time, so I can't ask you to go out for training anymore." . But working behind closed doors is not conducive to your cultivation, so I decided to leave a shadow clone to train you specifically."

"The reason why I called Kallen and Veretta here this time is because I hope you can learn and train together to enhance your own strength, okay?" Ito Chengzai said to Uchiha Miko and Karin. After that. He turned to look at Kallen and Veretta and said softly.

"Okay." Veretta agreed simply.

"Yes." Kallen nodded in agreement.

"Okay." Ito Cheng smiled and nodded to Kallen and Veretta, then turned to his shadow clone and said, "Please."

"Easy to say." The shadow clone smiled.

"Then I'll go now. See you next time." Ito Cheng looked back at the four people standing in front of him: Koso, Uchiha Miko, Kallen and Veretta. After saying that, his figure trembled and disappeared in front of several people.

"Hang Phosphorus, Miko, you two rest first, Kallen and Veretta, I will teach you the chakra extraction technique first." Shadow clone Ito Cheng said to the four of them respectively.

"Huh~ Shadow clones are really good things under certain circumstances." Ito Cheng sighed mentally when he reappeared in the Naruto World Hotel.

…………

More than a month later, in the evening, on the outskirts of another town. At this time, the clouds cover the moon, and two figures are fighting here, one meter apart and unable to see clearly.

"Ding~ding~ding~ding~" Several crisp sounds of gold and iron mingled in succession in the night sky.

"Okay, stop." At this time, another voice said.

"Very good. You have already mastered the basic physical skills. All that's left is to accumulate experience and figure out your own fighting rhythm." After a pause, the voice said to one of the figures again.

"Really? Does that mean I can practice ninjutsu?" In the sky, dark clouds gradually drifted away from under the moon. A handful of silver-white light shines on the ground, reflecting the face of the speaker. It was Ito Cheng.

"Yes." As the moonlight gradually expanded, two other figures were also reflected one after another, it was Steel Hand and Shizune. At this moment, Gang Hand said, "But are you sure you want to learn medical ninjutsu from me?"

"Of course." Ito Cheng nodded and confirmed, "You also said that my chakra attributes are yang due to your relationship. In addition to learning medical ninjutsu, it is very troublesome to practice other ninjutsu. In this case, there is You are such a ready-made medical master, why don't I learn medical ninjutsu from you instead of learning something else?"

"...That's fine." Steel Hand frowned slightly and agreed. Then he turned to Shizune who was standing aside and said, "Shizune, I will start instructing him in the practice of medical ninjutsu tomorrow."

"Yes, Lord Steelhand." Shizune, who had already put away the kunai in her hand, agreed.

Then Steel Hand, Shizune, and Ito Cheng left the suburbs together and returned to the hotel where they lived in the town to rest. Then starting from the next day, in addition to normal taijutsu practice, Shizune began to guide Ito Cheng in the practice of medical ninjutsu. Naturally, at the beginning, just like Sakura in the anime, she treated the dying fish and then tried to keep it alive.

This was no problem for Ito Shige, who was proficient in micro-control of energy and had a thorough understanding of life energy. Therefore, in less than two days, Ito Shige completed the initial introduction to medical ninjutsu and then started the next step. . Treat injured animals.

However, their route was either in a town or in the wild. Where would there be so many injured animals for Ito Cheng to treat, so in order to facilitate his practice, Ito Cheng simply captured the uninjured animals directly from the forest. Then create all kinds of injuries on them. For your own practice.

In this way, more than half a month later, Ito Cheng, who had mastered the treatment of injuries, was finally recognized by the steel hand and began to learn real medical ninjutsu. The first ninjutsu is the chakra scalpel.

…

More than half a year later, Ito Shige, who learned the medical ninjutsu - chakra scalpel, palm senjutsu, and the art of extracting minor troubles, and the ninjutsu - poison mist, and poisoned scalpel from Gangtou and Shizune, disguised himself as chakra. The strength was increased to a level stronger than that of ordinary chuunin, and then he began to learn Gangtou's original medical ninjutsu - the art of creation and regeneration and the medical ninjutsu - random rush.

As for the taijutsu - Kaili Fist, Tenshou Kick, etc., he had already mastered the basic taijutsu, and the medical ninjutsu - chakra scalpel and palm senjutsu were fully mastered, and the steel hand was taught to Ito Shige. And after more than half a year of hard practice. It has also reached the level of proficiency.

Of course, these are not the only things I learned. There are also the sealing techniques that Ito Cheng has been looking for, especially the sealing techniques used to make storage scrolls, which I also learned from Gangshou.

During this period, Ito Cheng also entered the Rubik's Cube world when he found an opportunity, and taught these medical ninjutsu and taijutsu to Karin, Kallen, and Veretta. As for Uchiha Miko, she continued her path of ninjutsu and illusion.

While wandering around, Ito Cheng followed Gang Hand and Shizune and wandered around the Land of Fire and the surrounding small countries for a whole year. I saw what it means to lose money and drink alcohol, but it also caused a lot of trouble. It added a lot of combat experience in medical ninjutsu to the new ninja disguised by Ito Cheng.

"I have taught you everything I can teach you. What you are missing now is just the accumulation of experience, but continuing to follow me will not allow you to gain much experience. So I decided to let you leave and practice alone." One night, Steele, who was eating and drinking in an izakaya, said to Ito Cheng, who was sitting opposite her.

"I understand." Ito Cheng said in a deep voice.

"Take this." Seeing Ito Cheng nodding in agreement, the steel hand took out an envelope that had been prepared for a long time and handed it to Ito Cheng and said, "If you think you can't gain much experience by practicing outside. Then take it Go to Konoha Village and give this letter to the Third Hokage."

Hear the words. Ito Cheng glanced at Gang Shou in surprise, but didn't say much. He nodded and took the envelope handed over by Gang Shou and carefully put it into his arms.

"Okay, let's go." Seeing Ito Cheng put the letter away, the steel hand suddenly became impatient and waved to him.

"Uh, okay." Ito Cheng glanced at Gang Hand with a look of displeasure, and said helplessly. Then he stood up from his seat, saluted Gang Hand and Shizune and said, "Thank you very much for this year. Thank you for your guidance.”

"Farewell." After Ito Cheng said this, he turned around and walked out of the izakaya, disappearing into the night after a while.

"Master Gangtou, can you let him leave like this?" After Ito Cheng left, Shizune looked at Gangtou beside her and asked.

Hearing Shizune's question, Steel Hand did not explain, but silently filled the wine glass in front of him and tasted it gently.

"It's been a year." Ito Cheng sighed softly as he gradually walked out of the town, and then thought to himself, "Although Steel Hand didn't teach me Wood Release in the end, these medical ninjutsu and taijutsu are also very good gains. "

Ito Cheng, who then walked out of the town, kicked off his feet and ran into the forest beside the street, quickly heading towards the place where the Kingdom of Fire and the Kingdom of Wind meet.

The town where Ito Cheng was previously located was in the southwest of the Kingdom of Fire, not far from the Kingdom of Wind, so within two days, Ito Cheng arrived at the junction of the Kingdom of Wind and the Kingdom of Fire. Then he took out the small black ball interrogator and determined the location of the three rebel ninjas who had gathered together half a year ago. He put away the small black ball and headed there at high speed.

More than twenty minutes later, Ito Cheng met the three rebel ninjas in a mountain forest.

"Sir." Seeing Itoge's appearance, the earth ninja rebel Matsushita Taro and the two grass ninjas came to Itoge's side at the same time and shouted respectfully.

"Take me to see those orphans." Ito Cheng waved his hand and said.

"Yes." Matsushita Taro responded, then turned around and walked into the forest with the other two grass ninjas, leading Ito Cheng.

However, just when they were about to enter the hillside where the orphans were, Matsushita Taro and the two grass ninjas jumped away from Ito Cheng, and then a loud noise broke out where Ito Cheng was, and a large group appeared gray and black outside. Smoke rose rapidly from the ground, and the blazing high temperature burned the ground into a piece of land in the blink of an eye.

"Is he dead?" A grass ninja asked nervously.

But as soon as he finished speaking, a black shadow suddenly appeared behind him and punched him away. Then there was a soft sound of "exposure", and the body of the Kusanagi flying into the air exploded violently. It came and flew out in all directions, a large amount of blood and internal organs spurted out from the split body at the same time, splashing onto the ground, making a "crash" sound.

"Run!" Seeing the tragic death of the grass ninja, Taro Matsushita, the traitorous earth ninja, shouted almost without thinking, and then activated the teleportation technique and rushed away. But just before Matsushita Taro and the grass ninja rushed out a few meters, their heads were dizzy at the same time and they fell from mid-air to the ground.

"Plop~" The body hit the ground and made a dull sound.

Then Ito Cheng walked up to the Kusanagi and Matsushita Taro and killed them on the spot.

"Hmph." Ito Cheng, who killed the three traitors on the spot and took back the small black ball consulter from them, snorted coldly and continued walking up the hillside. But what Ito Cheng saw next was an empty room, and he didn't see any orphans at all.

Knowing that he had been deceived, Ito Cheng suddenly raised his foot and stepped on the ground. A powerful force came out from the sole of his foot, and then he heard a loud "boom" and large cracks appeared on the ground. , the huge vibration force instantly collapsed the buildings standing on the ground, scattering them all over the ground with a chaotic "crackling" sound, and a large amount of smoke and dust rose from the ground.

"I didn't expect that the first time I used the castle foot would be to vent my anger." Looking at the messy ground, Ito Cheng said with a flash of self-deprecation on his face.
