Tanaka could no longer feel his chakra. This was not a big surprise when he realized that instead of chakra, he began to use MP when performing a jutsu.
And that's not all, using MP instead of chakra was much more fluid and powerful.
'Is this a similar version to natural energy?' He thought.
In this sense, it was as if he was always in Sage Mode.
His thoughts were interrupted when he made a new shuriken throw, and holographic pages appeared before him.
══════

[The skill: [Throwing Mastery] has been created.]
[[Throwing Mastery] (Passive) Lv1 EXP: 0.0%]
[Increases throwing damage by 15%]
[Increases throwing speed by 10%]
══════
'Is something like this possible?'
However, his mind cleared as he took a deep breath.
'So... Continuous actions can trigger a skill?'
It was an obvious question after seeing the descriptions of the created skills.
'And, if I use the created skill continuously, even without a living target, will it increase the skill level?'
A valid question. To test if he was right or not, he continued throwing shurikens while murmuring in his mind: 'Precise Throw.'
Only when he murmured out loud or in his mind was the skill activated. If he simply threw it, it would just be a normal shuriken throw.
"Whoosh!"
The sound of Tanaka's throws echoed as he had already made 50 throws.
On the 51st throw, a blue line appeared before him saying: [Throwing Mastery] level increased.
'Fascinating!' He murmured in his mind: 'Just as I thought, it is possible to level up the skill this way.'
Having discovered this, he did not stop his actions and continued throwing the shuriken.
On the 56th throw, another blue holographic line appeared: [Precise Throw] level increased.
Stopping his actions, Tanaka thought joyfully as he looked at the shuriken lodged in the targets.
If before he was at an acceptable level in shuriken use like any other Chunin ninja, now he felt he had become even more talented in shuriken use.
After a few hours of training with shuriken and kunai throws, Tanaka ran out of MP due to the constant use of 'Precise Throw.'
Opening the skill page, he clicked on the skill icon.
(A/N: I will only show what changed.)
══════
[[Precise Throw] (Active) Lv4 EXP: 11.6% / 2MP]
[Increases speed by 28%.]
[Increases critical chance by 28%.]
[Increases accuracy by 43%.]

══════
[[Throwing Mastery] (Passive) Lv5 EXP: 18.12%]
[Increases throwing damage by 35%]
[Increases throwing speed by 30%]
══════
'It increased a lot in just a few hours of throwing training...' he smiled while picking up the ninja tools he had used.
After doing that, he sat on the ground to meditate, to see if, like chakra, meditation would accelerate the speed of MP recovery.
Before, he had some difficulty focusing; however, now when he began to meditate, he felt more focused than ever.
Ten minutes later, he opened his eyes and murmured: 'Status'. Seeing that the MP bar was rising faster, unlike before when it only increased by 1 MP per minute, it now increased by 10 per minute.
40 minutes later...
══════
[A skill has been created by continuously performing an action!]
[The skill: [Meditation] has been created.]
[[Meditation] (Passive/Active) Lv1 EXP: 0.0%]
[A basic technique for chakra recovery and permanent chakra expansion.]
[The permanent chakra (MP) size depends on the amount of chakra (MP) when meditating.]
[The current chakra (MP) meditation yields 0 permanent MP.]
[Passively increases INT by 5%.]
[Passively increases WIS by 5%.]
[Passively increases VIT by 5%.]
[Passively recovers an additional 2MP per minute.]
[Actively recovers an additional 10MP per minute.]
══════
"Mm?" Tanaka opened his eyes upon hearing a bell sound in his mind.
Tanaka remained silent for a few seconds. He was in a state of great surprise.
Tanaka smiled shortly after thinking: 'Even while meditating, a skill was created and... This is a very good skill!'
No matter how much he looked, such a skill was far beyond an ordinary skill. Even if the emphasis was correct to say that it could do everything it described, like a permanent increase in chakra... Still, it didn't have such a significant number, and still being level 1.
It might seem that the MP recovery continues at the same amount, but the reality is that passively, he already recovers 2 MP, along with the 10 while meditating, making it 13 if you count the 1 per minute passively from his own MP.
34 minutes later...
Tanaka opened his eyes upon hearing a bell sound in his mind, and when he opened his eyes, he saw that the skill: [Meditation] leveled up.
══════
[[Meditation] (Passive/Active) Lv2 EXP: 0.1%]
[The current chakra (MP) training yields 11 permanent MP.]
[Passively recovers an additional 3MP per minute.]
[Actively recovers an additional 12MP per minute.]
══════
MP: [949/1,197]
Closing his eyes once again upon realizing that he still needed to restore 248 MP, he resumed meditating.
16 minutes later...
Opening his eyes, Tanaka stood up. His MP was fully restored.
As he looked at the sky, although he didn't have a watch, he judged it to be around noon.
'I'm starting to feel hungry.' He thought.
══════
In his room, after lunch, his continuous training resulted in two other skills.
══════
[[Transformation] (Active) Lv1 EXP: 0.0% / 20MP]
[A basic transformation technique that allows the user to alter their appearance to look like another person, object, or animal.]
[The duration and accuracy of the transformation depend on the skill level and chakra (MP) used.]
[Additional cost: 10MP per minute while the skill is active.]
[Reduces execution time by 15%.]
[Increases seal accuracy by 30%.]
══════
[[Clone] (Active) Lv1 EXP: 0.0% / 10MP per clone]
[A basic cloning technique that creates an illusory copy of the user.]
[The clones have no substance and disappear when hit.]
[The number of clones and their durability depend on the skill level and chakra (MP) used.]
[Maximum number of clones you can create at the same time: 5.]
[Additional cost per clone: 5MP per minute while the skill is active.]
[Reduces execution time by 15%.]
[Increases seal accuracy by 30%.]
══════
He felt disappointed to see these abilities. Perhaps they seemed too simple? Especially compared to [Meditation].
'No, I shouldn't lament,' he thought. 'If the properties of these skills increase, they will also become a triumph for me!'
Putting this aside for now, he went to the corner of the room, and when he picked up a scroll to store, something happened.
══════
[You have obtained the skill scroll: [Sealing Technique]]
[Would you like to learn the skill?]
[Confirm]-[Deny]
══════
Without thinking twice, mainly because this scroll belonged to him, he clicked on [Confirm].
══════
[You have obtained the skill: [Sealing]]
The Sealing Technique is a standard ninja skill that allows you to seal a variety of items using space-time ninjutsu.
[[Sealing] (Active) Lv1 EXP: 0.0% / 5MP]
[Increases sealing capacity by 10%.]
[Reduces execution time by 5%.]
[Increases seal accuracy by 15%.]
Range: Up to 5 meters
══════
'I still need to make the seals, but I feel I can execute with more speed and precision, which is a good thing.' He thought.
There were other scrolls in his room. For him who belonged to the Uzumaki Clan and, although orphaned, his aunt Akane was Ashina's granddaughter, and as a distant cousin living under her care, such scrolls were accessible to him.
When he picked up the next one, a new page appeared.
══════
[You have obtained the skill scroll: [Unsealing Technique]]
[Would you like to learn the skill?]
[Confirm] – [Deny]
══════
He confirmed.
══════
[You have obtained the skill: [Unsealing]]
The Unsealing Technique is a standard ninja skill that allows a ninja to summon a variety of items that have been stored using space-time ninjutsu.
[[Unsealing] (Active) Lv1 EXP: 0.0% / 3MP]
[Increases unsealing efficiency by 20%.]
[Reduces execution time by 15%.]
[Increases unsealing accuracy by 25%.]
[Allows undoing basic and intermediate sealings.]
[Range: Direct contact.]
══════
He had many doubts and questions, but for now, he set everything aside as he went to his secret safe, opening it and taking out a scroll.
══════
[You have obtained the skill scroll: [Adamantine Sealing Chains]]
[Would you like to learn the skill?]
[Confirm] – [Deny]
══════
His heart pounded hard. With a trembling hand, he clicked on 'confirm.'
"Vrrr!"
The screen shook, emitting a sound resembling a bell, and soon a message in red overlapped the holographic skill learning screen.
══════
[You cannot learn this skill. Prerequisites: 121 INT, 100 VIT, and 50 WIS]
══════
"Urgh..." He groaned softly.
Although he felt a bit frustrated, there was also a hint of joy in his eyes.
Instead of putting the scroll back in the safe, he murmured: 'Inventory.'
When he did that, a large holographic page appeared divided into two parts. On the left side was a tab similar to equipping items on a game character, with slots for a weapon, shield, armor, accessories, etc. On the other side, there was another window divided into grids of 4 slots by 5 slots, totaling 20 free slots.
When he thought of storing the scroll in his hand, the scroll seemed to disintegrate into golden flower petals, and soon it appeared in the first slot of the inventory.
'Such a thing really existed.' It was just a test, something that should have been obvious to test before, but he simply forgot and only now tried to see if there was something like an inventory.
Grabbing a ninja pouch with several shurikens and kunai, instead of thinking about placing it in the inventory, he simply tried to pass it through the inventory window, and as he imagined, it also worked and occupied the second slot.
'So, if they are all in a pouch or something like that, even if they are different items, it's still possible to occupy a single slot...'
This confirmation also expanded the way he could use the inventory. Something that would be more useful than using sealing scrolls.
'Maybe I should start thinking about using something like a sword?' He thought.
Although the strength of the Uzumaki lineage is seals, now that he had a growth system, there was no way he wouldn't want to take advantage of it.
Another thing he only speculated on given everything that happened. The fact that continuous actions could trigger skills, even making a skill from those he had learned before, even meditation, made him believe that continuous physical training could create a skill or even yield attribute points.
With that in mind, he left the house again.
══════
In the training area, Tanaka began doing push-ups.
"211!"
══════
[You have obtained 1 STR by continuously doing push-ups]
══════
'Something really happened and... Just as I expected, it was an increase in the attribute point!' A smile adorned his lips as he continued to do push-ups until he couldn't take it anymore.
He wasn't afraid of getting injured or anything like that. Since he had a player's body, such a thing shouldn't exist. At most, he would lose a bit of HP from getting hurt, but as long as he gained points, he felt it was worth it.
An hour later...
══════
[You have obtained 2 STR by continuously doing push-ups]
══════
Dripping with sweat, he stopped his actions, lying on his back, looking at the sky while breathing softly.
