I only know the golden light spell, I am a ninja in Konoha

Tsunade took out a scroll from the drawer next to her and threw it into Xu Hong's hand, saying: "Look, this is how I improve Konoha's overall strength!"

Xu Hong spread out the scroll in his hand and found that it was the method of accelerating the movement of qi and blood that he had created originally, but there were great changes in the details.

Tsunade smiled and said: "I found this in the root information. I heard that you created it yourself. I relied on my own medical knowledge to make some improvements. As long as I practice no more than one hour a day, it will not affect my lifespan. .”

Xu Hong studied it carefully and said with a smile: "As expected, he is the strongest medical ninja in the ninja world. His research on the human body is probably not matched by many in the ninja world.

It just so happens that I am researching ways to strengthen the human body during this period. Once successful, combined with the method of qi and blood, I should be able to improve the physique of Konoha ninjas a lot.

But those who can learn it, Tsunade-sama, should think carefully about it. The method of qi and blood is still very easy to learn. If it goes to other ninja villages, it will not be good for Konoha! "

Tsunade smiled and said: "I don't need you to worry about this. Practicing this secret technique still requires certain physical fitness. Those who are able to practice it, I choose jounin, they know the appropriateness!!"

He handed the scroll to Tsunade again and said, "Then I will continue to create ways to improve the physique. Count your money slowly!"

After coming out of the Hokage's office, Xu Hong went to the back mountain and continued his practice, looking for a breathing frequency that could absorb natural energy.

Xu Hong had no tricks. He could only constantly sense the frequency of natural energy with his mind, constantly adjust his breathing rhythm, and try to absorb natural energy.

Soon Weasel came to the back mountain, holding a few game meats in his hand, and consciously put them on the barbecue grill next to him, and started to barbecue with flames coming out of his mouth.

Feeling the qi and blood in Weasel's body, Xu Hong smiled and said, "You practice my qi and blood method!"

After he stopped breathing fire, Itachi said with a smile: "The burden of turning on the kaleidoscope is really big. I also have to find ways to improve my physique, otherwise I guess I won't be able to keep up with your growth rate."

Xu Hong smiled and said: "It just so happens that I have recently been creating my own method of absorbing natural energy based on the rhythm of breathing. Come over and help me!"

Itachi said in shock: "Absorbing natural energy, are you creating your own magic?!"

Xu Hong: "It's not an immortal technique, it can't be compared with an immortal technique. The breathing method I created absorbs only a trace of natural energy. At most, it regulates the body with breathing. It has no effect of magical techniques. It's just a method to relieve the qi and blood. The sequelae can slightly increase a person’s lifespan!”

Itachi: "That's awesome, what exactly should I do?!"

Xu Hong looked at the barbecue on the grill and said with a smile: "Let's eat first, and then we'll talk after we finish!"

Itachi shook his head helplessly, and the seasoning appeared in his hand, and he began to brush it on the barbecue, and the fragrance slowly spread out.

After simply eating barbecue, Xu Hong began to teach Itachi how to breathe. After a long time, Xu Hong also felt that with a special frequency, wisps of natural energy were absorbed by Itachi, slowly improving his body.

But I don't feel it. This is a constant thing, and it takes time to get results.

Itachi kept it up for a while, then couldn't hold on anymore, and began to breathe heavily, murmuring: "I didn't expect that it is really difficult to maintain this kind of breathing rate. I have never stopped meditating in these years, and I can't do it like this." It only lasted less than half an hour!”

Xu Hong said with a smile: "Seeing your state, I know that the breathing method has been successfully created. If I make a few changes, it should be popularized!"

Itachi also laughed. After finishing this set of breathing, he also felt an inexplicable relaxation in his body. Knowing that this method was very useful, he was also happy for Xu Hong.

With Itachi's help, Xu Hong finally perfected the breathing method in the next half month.

Looking at Itachi, Xu Hong said seriously: "This breathing method cannot be taught to too many people. Only those you truly trust can teach it, otherwise it will cause chaos!!"

Itachi nodded and said seriously: "I know how to do it. At most, I will pass it on to my brother!"

Xu Hong rolled his eyes. He was just a disciple and didn't want to say anything more.

He stood up and ran towards Konoha, and soon arrived at the Senju clan's territory, where now besides Tsunade, Uzumaki Shiori's family lived.

Uzumaki Shiori was also discharged from the hospital during this time, and Tsunade personally found a job as a nurse in the hospital to earn money and raise her. She was enjoying her current life.

After getting closer, he saw that Xiang Lu was helping his mother dry clothes. Xu Hong smiled and said: "Xiao Xiang Lu, how are you doing at school during this time?!"

Xiang Lian showed a helpless expression and said with a bitter smile: "There is an Uzumaki Naruto with the same surname as me in the class. Like an idiot, he pesters me every day, thinking that we are related!"

Xu Hong smiled and said: "Your ancestors are indeed related, his mother is the princess of the Uzumaki clan.

Not to mention these, how many sealing techniques have you learned from the Uzumaki clan? This is the most suitable for you! "

Xiang Lian showed a wry smile and said: "Although Granny Tsunade has become my teacher, the sealing technique is too troublesome, and it took such a long time for a warlock to learn the sealing technique. As for the sealing technique, I haven't learned it yet!

However, the Vajra Blockade inherited from the bloodline can be used reluctantly! "

As soon as he finished speaking, the thin golden chains slowly came out of Xiang Ling's body, and eight chains less than half a meter were waved wantonly.

Xiang Ling showed a proud expression and said: "By the way, Brother Xu Hong, why are you coming to my house?!"

Xu Hong gently rubbed Xiang Lu's head, "I'll teach your mother a way to regulate her body. As long as she persists, she should have no problem living for more than twenty years. Then Xiang Lu will have to supervise her mother's studies. ah!"

Xiang Ling's eyes were also full of excitement, and he said happily: "I will supervise my mother!"

After entering the house, Xu Hong taught Uzumaki Shiori the rhythm of the breathing method, and also taught Xiang Lian, and asked her to supervise her mother to practice well after returning home every day.

In fact, there was no need for supervision. When Uzumaki Shiori heard that he could live for a few more years, he took it very seriously and studied very seriously.

After teaching the two breathing techniques, Xu Hong said goodbye and returned home, where he saw Naruto holding a paint bucket and getting ready to go out.

The moment Naruto saw Xu Hong again, he also hid the paint bucket behind his back. He looked at Xu Hong with some tact and said in a trembling voice: "Brother Xu Hong, why did you come back?!"

Xu Hong stretched out his hand and said sternly: "Hand it over! Don't always think about pranks at a young age. This will only make everyone hate you more, Naruto!"
