Naruto continued to mix the two Energies, forming them into Chakra. He wanted to see what capacity of Chakra he had in his body, and prayed that it would not be too small. The more Chakra he can mix, the better it will be for his health. When he fills his entire capacity, only then will he try to increase it somehow.

He also noticed after a week that the time to replenish Physical Energy in his cells was reduced by less than ten minutes. It wasn't much, but for a long period of time it was really good, and on top of that he expected it could get even shorter in the future if he kept creating Chakra all the time.

He also has more than ten times more Spiritual Energy in his body than Physical Energy. On top of that, Spiritual Energy seems to be quite strong in him, but he is not yet able to determine how helpful it is for him.

If he is able to determine how many Chakra units he has, Naruto decided to translate Physical and Spiritual Energy into units as well. Physical Energy he has exactly 0.1 units, which is how many Chakra units he is able to create in less than three hours. For Spiritual Energy, on the other hand, he has more than 60 units, which is a colossal difference. This is even more than ten times more than he thought! For at least one thing, he even has a lot in him, come on, if you look at other Shinobi, it's still low.

To mix 0.1 units of Chakra, Naruto uses all of his Physical Energy, or 0.1 units, and combines it with 0.1 units of Spiritual Energy. To mix 0.1 units of Chakra, he has to use, up to twice as many units of Energy, which can be a bit confusing. However, these 0.2 units of Physical and Spiritual Energy are combined into "one" and they do not work by weight. Mixing the Energies looks in itself like trying to merge them, the two Energies naturally merge and the process is mostly automatic. Naruto simply has to focus and try to "mix" them in a vortex.

Despite the damaged Chakra Circulation System, Naruto can feel the Chakra moving throughout his body. For the most part, it resides in a place identified as the Chakra Core, but it likes to move to random places. It only enters the Chakra System when one concentrates and wishes to manipulate it to create some technique using hand seals. Chakra itself is not stored in the Chakra System, because that is not its job, but in the body, all the cells of the body, and it is constantly moving through them on an energetic level. The body is like a container for Chakra, the stronger the body, the more Physical Energy we have and the capacity of Chakra itself increases.

A few days passed as Naruto thought about how to hide his Chakra from Tsunade. He thought of a way to disperse the Chakra back into two individual Energies, but was unable to do so. It required incredible control over Chakra, and Naruto had almost none, even with such a small amount of Chakra. Because of his damaged Chakra System, he was not even able to practice Chakra control. Even if he had dispersed it into two individual Energies, he doesn't know how he would be able to hide the unlocked Tenketsu.

At one point, he suddenly widened his eyes in surprise, getting an idea. He left his room and walked slowly down the stairs to the kitchen, where Kushina was busy cleaning. She, seeing him coming down alone, was horrified immediately and shouted at him angrily.

- Naru-chan! You've gone mad! - within a second she appeared by his side and grabbed his shoulders, helping him.

Naruto sighed. Even if his best days are gone and he has "slight" mobility problems, he doesn't want to rely on anyone to keep his body strong for as long as possible. Otherwise, quickly, his already small amount of muscle will atrophy.

- Ka-chan...! - cried Naruto angrily - I'll be fine, don't fret...!

He had to listen to her tirade for a while and wait for her to calm down before asking her for a certain thing.

A few minutes later, sitting on a chair in the kitchen, he started a conversation with her - Ka-chan, I have a request...! He wants to contact Itachi-san, last time we talked for a while and even liked each other, so he wants to meet him...! - asked his mother, who seemed happy to hear this.

- Really? That would be great! You never brought friends home! - she exclaimed joyfully.

- I didn't say he wanted to meet him here.... - he said.

Kushina furrowed her eyebrows - I won't let you go alone to some place, we can only go together to visit them. I'll make friends with his Ka-chan and we could have dinner together - she suggested, but Naruto shook his head, rejecting this proposal.

- I'm sorry, but I'd rather just talk to Itachi-san for a while, I need some advice... - he explained to her.

- I understand... - she sighed sadly. Ever since she gave birth to Naruto, their contact with Mikoto had broken off and they hardly ever talked, so she thought it would be nice to get together for a family dinner.

Naruto felt bad, seeing the disappointment on his Ka-chan's face. For a moment he forgot himself and focused only on his needs.

He sighed in his heart - Sorry Ka-chan, let's do it some other time.... - he said quietly. Kushina looked at her son surprised and smiled softly.

- Sure...! I'll count on you!

....

The next evening in his room, Naruto talked with Itachi. It was the only place where they could talk in a good way.

- I understand, it's really... amazing...! - admitted the surprised Uchiha. He didn't expect Naruto to get around his illness in such a way.

- Yes, I thought about it for a long time and minimized the risk to the lowest level, however, I did not expect my amounts of Physical Energy to be so low.... - sighed Naruto.

- It's probably depressing, but I have a feeling something will find a way - admitted Itachi honestly - So what do you need me for now? Will I be doing something dangerous to your health...? - he asked cautiously.

- Dangerous no... - laughed Naruto - But illegal

Itachi sighed.

- I need you to cast an illusion on me with your Sharingan...! - announced Naruto seriously.

- For what specifically? - asked a surprised Itachi. He needed to know first what Naruto wanted to get out of it before he agreed.

- You see, I have my weekly checkup with Tsunade and don't want her to detect that I possess Chakra. I want you to cast an illusion to make it seem that my Tenketsu are blocked and my Chakra is hidden

Itachi nodded his head in understanding. It was a good move and not something he would disagree with.

- Okay, I am able to do this for you, how long should this illusion last?

Naruto mused. He wasn't sure how long he wanted to keep it hidden, but probably as long as possible.

- How much Chakra would you use for a period of.... six months? - He asked and heard a sigh from Itachi.

- Fortunately, it's a simple illusion, but in order for it to last that long, I would have to use almost half of my Chakra...! - he admitted, surprising Naruto with this.

- Oh... It was actually predictable.... - he sighed.

- Is there anything else I need to know before I start? - he asked Naruto about it. He preferred to know something if it was important and take it into account.

- No, you can start - he replied.

Itachi wordlessly activated his Sharingan possessing the Three Tomoe in each eye and formed several hand seals.

- Sharingan: Genjutsu!

He called out quietly, and the Sharingan in his eyes swirled several times. Naruto felt a few subtle changes in himself, but the sensations quickly disappeared and everything seemed normal to him.

If it weren't for Itachi's heavier breathing due to the exhaustion of a large amount of Chakra in an instant and a few drops of sweat on his forehead, he would have concluded that nothing happened.

- Here... - Naruto handed him a cloth to wipe his face.

- Thanks? - Itachi looked strangely at the pink cloth with green toads.

- You don't have to give it back, I'm disgusted by its appearance and I certainly wouldn't use it after you.... - he stated with clear disgust in his voice.

- Ah... Sure - replied Itachi awkwardly - Do you feel any change in yourself? - He asked changing the subject.

- No, but I hope it's working

- Of course - replied Itachi confidently - From now on Tsunade-sama won't be able to see the open Tenketsu and your Chakra, but be careful about the research being done. She herself may not notice the illusion and will think everything is fine, but on technology my illusion does not work - he explained warning him.

- Don't worry about it - Naruto waved his hand - I'm really grateful to you, I owe you a favor or even two...!

- I know, he doesn't risk for you for free - smiled Itachi slightly, which was quite a rare sight.

...

From now on, with the problem of hiding the changes in his body out of his mind, he could calmly increase his amount of Chakra without fear of anyone detecting it. He had already confirmed this, at his weekly checkup, Tsunade had not noticed any difference in his body, so he was absolutely calm.

In those two weeks since his Chakra awakening, Naruto has gained nearly 11.5 Chakra units. Definitely the rate of increasing its amount was too slow! He had to somehow increase his Physical Energy, which severely limits Chakra production, by its small amount.

He couldn't train in any particular way, because he risks detaching his muscles from the rest of his body. However, that was the only way he could think of for now. Nothing else really worked. Cold baths, saunas, a good night's sleep and many other things that are scientifically proven to increase Physical Energy in the body didn't really work much with him.

If he is to start any training, he must surely do it in secret, because even when he tried to train at the age of 6 and 7, his parents forbade it. But now they can't stop him, and his training can't be about building muscle mass, because that won't work out, but about increasing the endurance of his already minimal amount of muscle in his body!

- I need to increase the strength of not only the body and muscles, but also the bones! This must be my basis, now only to choose the right exercises....

And the best exercises are the most simple and basic ones that also won't arouse much suspicion in anyone, that way no one can accuse him of anything.

Since that day, Naruto increased the amount of his movement, he tried to walk alone, even if other household members shouted at him. In addition, he moved around his room a lot. He tried to stand on one leg while keeping his balance, and sometimes even did a plank on the floor. Unfortunately, he wasn't able to do a single push-up, and squats were quite challenging for him. He tried to increase the amount of time he spent outside to bring fresh air into his body, and also meditated in the field. He increased the appropriate amount of food in his diet, so that he also did not gain unnecessary fat. His diet was really healthy, unlike the likes of Himiko, who liked to overeat ramen. He ate a large amount of fatty fish and meat, nuts or legumes, and drank various herbal teas designed to improve his overall health.

Over the following weeks, not only did his Physical Energy increase, but even his Spiritual Energy increased! Maybe his body didn't return to the state where he was "the healthiest and fittest" in his entire eight-year life, that is, ages 6 and 7, but it was still really good. He felt much better than before!

His overall performance improved a bit, and his parents became more hopeful in their hearts.

As for his life energy, he's not sure if it increased thanks to Chakra, but it's possible that it did. Well, it's too early to tell anything for now anyway.

Now his Physical Energy regeneration time has decreased from almost three hours, to only two! In addition, it has increased from 0.1 units, to almost 0.3 units! As a result, he is able to increase his Chakra by slightly more than 25 Chakra units per week! It increased from 5.6 units to, as many as 25! This was several times more!

Naruto was truly satisfied and within 7 weeks of opening the Tenketsu, he had filled his entire Chakra capacity. He felt the Chakra limit when he reached the amount of 80 Chakra units in his reserves, which was quite a small result, because an ordinary civilian has between 100 and 120 Chakra units from his calculations. Come to think of it, with his weak body this result should have been, not at 80, but at 30 units of Chakra, if not for his genes of the two great Clans.

Naruto sighed to himself. Now he would have to look into increasing his Chakra capacity and at least get some sleep at night, since he wouldn't have to wake up every two hours to produce more Chakra. This kind of lifestyle was really tiring, and his regeneration and quality of sleep had decreased tremendously during this time.
