"Woke up?"

"Hmm. Stretching, Naruto wiped his sleepy eyes and prepared to get out of bed and wash.

"It's already done early, so come and eat it when you wash your face." The girl said to Naruto, but the pen in her hand didn't stop, and it seemed that she was dealing with some official documents.

Sensing that the boat was rocking a little today, Naruto asked her his own question as he brushed his teeth.

"It's raining outside, it's going to be a long time coming, so don't go out if you're okay during this time, stay in your room." The girl's expression was focused, holding a pen to review the official document, showing a different style, and the hair on the left forehead was simply tied with a headband, adding a little softness to her.

After washing, Naruto picked up the bread on the table that was still warm, ate it with milk, and asked casually, "Do you get up so early every day?"

The girl stopped her pen and tapped Naruto's head lightly with the barrel of her pen, emphasizing once again what she addressed herself, "Call me sister." I'm also the leader of this team, so I have a lot to do. ”

It seems that a lot of pressure has accumulated.,In order to relieve the mood, the girl stretched a lazy waist.。 Although believing that the girl didn't mean it, Naruto felt that the girl's inadvertent actions always tugged at his heartstrings.

Three or two bites settled the rest of the bread, and Naruto also returned to the bed, ready to start the cultivation he had stopped for a long time.

"What are you going to do?" the girl asked with some curiosity as she watched Naruto quickly solve her breakfast.

"It's kind of finding something to do for yourself, it's too boring to do nothing all the time. Naruto sat cross-legged on the bed and began to refine the chakra. Since Chakra's refining practice had not been going on for too long before he was forced to stop, now when he was refining again, Naruto actually felt that his meridians were slightly blocked.

Looking at Naruto refining the chakra, the girl put down the pen and looked at it for a while, then interrupted, "Stop, the refining method of chakra is wrong." ”

Naruto never had doubts about the correctness of his chakra's refining method, if he wanted to ask why, after all, this was what Naruto learned from the scroll given by the three generations, Naruto didn't believe that the three generations would give him a wrong scroll to cultivate, but he still stopped and wanted to hear what she had to say.

"I shouldn't be wrong with the method of refining, right?" asked Naruto as he stopped refining.

"Indeed, there is nothing wrong with your method of refining in the ordinary sense," said the girl, pausing and organizing her words to explain in more accurate language, "but this method is too inefficient. ”

"Too inefficient?" For this method, Naruto had heard for the first time, is there still a high ground in the efficiency of the chakra refining method?

"Hmm. The girl made a vase-shaped seal with both hands and said to Naruto, "Follow me." ”

After watching Naruto obediently make the same seal, the girl nodded in satisfaction and told him in detail about her method of refining chakra.

"Chakra's refining is to gather physical energy and spiritual energy at a place about three inches below the umbilicus, and after converging, it seems that spiritual energy and physical energy have been fused together, but in fact, it is not. After they are refined, they are simply poured into a 'container' under the umbilicus, and when using ninjutsu, the caster extracts the two separately and spins and fuses them together, which forms ninjutsu. Because the physical energy and spiritual energy stored separately are easy to dissipate without a stable form, a large part of it will be lost in vain.

The method I teach you is different from the ordinary refining method, it requires the node of refining inside one's body to open other 'containers', and the extracted physical energy and spiritual energy are preliminarily fused at the nodes in advance, and then stored in the subumbilicus 'container' for further fusion. Because it has a stable form, the refined chakra is not easy to dissipate. This not only reduces the proportion of natural dissipation and increases the capacity of chakra, but in case of emergency, you can also extract chakra directly from these nodes to achieve the effect of quickly releasing ninjutsu. However, if you do this, you will put too much burden on your own meridians, and you should never use it unless you do it.

Another benefit of this chakra refining method is that it can increase your affinity for water attributes, and the effect of practicing in places with dense water vapor will be doubled, and the sea you are in now is undoubtedly the best place to practice. ”

After listening to the girl's words, although she wanted to learn in her heart, she knew that this method must be very precious, and hesitated and said, "This method must be very precious, right?

The girl just laughed at this and said with relief: "Don't worry, this method can be done by everyone on my side, and it is not a big deal." Within my family. The last sentence the girl didn't say, she didn't want Naruto to be too burdened by it.

Naruto is not a hypocritical person, and he is also quite interested in ways to make himself stronger, and when he heard the girl say this, he accepted it with gratitude. I tried to refine the chakra according to the method that the girl said, but I felt that the condensation of the chakra became more difficult, especially at several points almost stagnant, as if something was blocking there.

Looking at Naruto's furrowed brow, the girl smiled and asked, "Do you feel that the refining of chakra has become difficult, and it feels like something is blocking the node?"

Naruto stopped refining the chakra and nodded, waiting for the girl's answer.

Looking at Naruto's well-behaved baby who humbly asked for advice, the girl's vanity was greatly satisfied, and she explained to Naruto, "Of course. It's your first time doing this kind of practice, and the node has not yet been developed, so what you have to do now is to carve out a warehouse in the originally small cave where you can store items, and of course you feel difficult. But when the warehouse is dug out, you can store things in it, so the bigger your warehouse is, the more things you can store, and the stronger you will be!"

Nodding, Naruto calmed down again, and with his huge spiritual power, he entered the state of inner vision. According to the girl, each person's node position is different, and if you want to practice this method of refinement, you must find the node that suits you most and develop it. The higher the degree of development, the greater the quantity, the stronger that person will be.

His first node was located in the middle of the body, and according to the cultivation method that the girl said, Naruto saw that the two air currents that were originally going straight began to circle and entangle at that position, gradually forming a spiral of air flow towards the dantian. However, the formation of the air currents did not go smoothly, and due to the narrow space of the passages, they would often hit the walls and scatter, leaving Naruto to have to struggle to maintain their rotation.

Naruto could roughly guess that these two air currents were physical energy and spiritual energy, according to the girl's method, with the help of the experience of his previous life, Naruto controlled the two air currents to accelerate and rotate, and with the help of the power of rotation, they collided fiercely with the surrounding walls.

At the moment of the collision, Naruto only felt a sharp pain coming from the acupuncture point in his body, but fortunately, Naruto had a similar experience in rushing acupoints in his previous life, which allowed Naruto to grit his teeth and not make a sound. Although no sound came out, the pain caused by the rush made the sweat soak the clothes, and the spin that was barely maintained dissipated.

The girl not far away was in a hurry when she saw this scene, and hurriedly ran over to support Naruto, who was about to fall, and scolded: "Are you stupid? You have only been practicing for a long time before you rush the acupoints, don't you want to die! The method of cultivation emphasizes gradual and gradual progress, do not rush to the acupoints, and the acupuncture points must be skillfully controlled by the fusion of physical energy and spiritual energy, and the acupuncture points can only be carried out after a long period of warmth, didn't I warn you again and again!"

Naruto, who had been lying in the girl's arms for a while, recovered a little, but his face was still pale. In fact, Naruto's injury was far less serious than the girl thought, Naruto has a strong spiritual control ability and martial arts practice experience in his previous life to learn from, so although it seems that Naruto's injury is not light on the surface, Naruto knows that this is just caused by the success of the acupuncture point and the depletion of qi and blood.

Smiling weakly, Naruto made a triumphant gesture to the girl who held him in his arms.

"You guy...... Could it be ......" The girl asked Naruto in disbelief for her unbelievable guess.

"The first step has been successful, although it is small, but all that remains is to slowly expand it. "Naruto's physique is already special, and with the help of the Nine-Tails Chakra, Naruto has recovered a lot after resting for a while.

Naruto's words obviously had a big impact on the girl, and when she remembered the time when she first rushed to the hole, she felt a little embarrassed.

This kid is a genius.

"Don't move!"

Seeing Naruto sit up cross-legged again, in a posture with his heart facing the sky, the girl next to him tightened his heart, thinking that he was going to make some dangerous move, and hurriedly pulled him over and pressed him in his arms.

"Whew, what are you doing? Naruto, who had finally struggled out, looked at his sister who had launched an offensive inexplicably, and said helplessly.

The girl put on a reasonable look, glared at Naruto and accused, "You want to continue to rush the cave again, don't you? No matter how talented you are, your body can't withstand such an impact, you will only destroy yourself like this!"

Naruto looked at his sister with a smile and a smile, so as not to disturb her, he had to explain, "It's not a punch, it's just a way for me to adjust my body's breathing." ”

"Not a punch?"

Faced with the girl's undisguised suspicions, Naruto had to carefully explain his behavior to her, as well as its principles and benefits. After listening to Naruto's explanation, the girl was still a little unconvinced, and decided to try it herself.

Naruto wasn't worried at all, although this world couldn't feel the qi of martial arts, but ordinary meditation could still be done, and meditation was just a way to calm his mind and relax his body more efficiently.

After a short while, the girl opened her eyes, looked at Naruto with bright eyes, and asked excitedly, "How ...... this method?"

Looking at the girl who wanted to speak, Naruto smiled and said, "In my hometown, it's just a trick that everyone can do. ”
