Konoha Village.
Evening.
Hyuga Clan's residence.
Hinata, with short dark blue hair and Byakugan eyes, had just finished her sparring session with Hanabi.
Sweating profusely, she went to the bathroom as usual to wash off the sweat.
As the water drenched her fair skin, Hinata reached for the shower gel but felt something hard instead.
It was an exquisitely made diary with gold trim, and on its cover was written: [Takasaki's diary (Hyuga Hinata)]
...
Inside an ordinary single-story house.
Takasaki, lying on a wooden bed, looked at the translucent panel in front of him and the diary that had suddenly appeared on the table.
After confirming it several times, he finally let out a sigh of relief: "After three years of transmigration, the system has finally arrived."
There's no need to mention his past life; his current identity was that of an ordinary student at Konoha Village's Ninja Academy, in the same class as Naruto, Sasuke, and Sakura Haruno. His parents had died in the war long ago, leaving him with a house and just enough money to get by.
He surveyed his home environment again.
He lived in a single-story house on the outskirts of the city.
The walls were whitewashed plaster, showing some cracks due to age.
A low-wattage screw-in light bulb on the ceiling cast a dim yellow light, and the wiring was external.
Fortunately, the floor was covered with wooden planks, which Takasaki had mopped, making it relatively clean.
The bathroom mirror looked as if it had been punched, with many pitted cracks, unable to reflect a complete face.
A wooden bed, a solid wood table, a few folded high stools, and a wardrobe were basically all the presentable furniture in Takasaki's house.
Of course, the iron pot in the kitchen, which was too small for two people, could also fetch a few coins if sold.
In short, his family was very poor.
The good news was that his appearance was no less handsome than Sasuke's, and his length was enough to conquer all female Ninja in the Ninja World.
The bad news was that his talent was truly mediocre; currently, he couldn't fully master the Three Body Technique, making him a dead last in school, just like Naruto.
Next, it was time to understand the system's functions.
As long as he wrote a diary in the diary provided by the system, he would receive different rewards.
Furthermore, the diary could be recalled into his consciousness space at any time, so there was no need to worry about his diary content being seen by others. He could write whatever he wanted, freely and uninhibitedly.
It was a very simple function description; indeed, he could become stronger just by writing a diary.
Takasaki no longer wanted to be the dead last in his class, so he picked up his pen and began to write:
[Who writes a diary if they're a proper person? If I write one, it'll be about improper things.]
[Anyway, no one else can see my diary, so I'll just write freely.]
[Today, I borrowed Hinata's notebook. Hinata still blushes whenever she's shy. She's still developing and probably doesn't know how magnificent her figure will be in the future, right? If I marry her and bring her home, she'll easily be played out.]
[There are many beautiful women in the Ninja World. Kurenai Yuhi-sensei, the older sister type, I could play with those beautiful legs for a year.]
[Ino, the young lady of the Yamanaka Clan, will have a figure as good as Hinata's when she grows up. Of course, her personality is spicier than Hinata's. When I'm with her in the future, I can let her get on top and move herself.]
[The most outrageous figure still belongs to Tsunade. With that pair of snow-white, ample granaries, my children and I will definitely not go hungry in the future.]
[As for Sakura Haruno, she's good-looking, but unfortunately, she's Sasuke's simp. I don't care for her, unless she becomes my simp. She's so good at simping, her technique must be excellent.]
[And Mei Terumī, Temari, Konan, Karin, Tenten, Hanabi... they are all female Ninja of exceptional beauty. Who should I marry in the future?]
[Only children make choices. If I have the chance, of course, I want them all!]
[Luckily, they can't see these improper things in my diary, otherwise, it would be difficult for me to get by in the Ninja World in the future.]
[That's all for today's diary. I'll rest for a bit, then I have to return the notebook I borrowed from Hinata to her.]
After finishing the diary.
Takasaki put down his pen, waiting expectantly.
One minute, two minutes, five minutes passed, but no reward was received.
Takasaki was not in a hurry and continued to wait patiently. The system would not lie; presumably, the system had not yet determined whether his diary was finished.
Ten minutes passed.
The system's voice sounded in Takasaki's mind:
[First diary entry complete]
[Friendly reminder: As this is your first diary entry, no evaluation is required to receive a reward. Your subsequent diary entries will need to be evaluated to ensure they contain true and valid events.]
[Reward received: Chakra volume and stamina increased by 100%.]
[Basic Three Body Technique acquired: Clone Technique, Substitution Technique, Transformation Technique.]
The Three Body Technique was a skill he could never learn at the Ninja Academy. After all, he was just the child of a civilian Ninja, and compared to his classmates who possessed Bloodline Limits and family inheritances, his progress was truly slow.
This had led him to worry about the Ninja Academy's graduation exam three days later.
Now the situation was different.
Takasaki felt a warm current washing over his body, circulating within him in the form of Chakra, integrating into his cells.
His originally fatigued body became full of vitality.
His stamina was abundant throughout his body.
His physical condition was so good that he wanted to use Ninjutsu to find someone to fight right now!
Takasaki paid attention to the system's friendly reminder.
That is to say, the next diary entry must record true and valid events to receive a reward.
It didn't seem difficult.
However, Takasaki's attention was currently focused on the Ninjutsu he had acquired, eager to try them out.
"Clone Technique!"
Takasaki immediately formed the hand seals, and a puff of smoke appeared beside him.
As the smoke dissipated, a clone identical to him appeared.
Then he used the Substitution Technique and Transformation Technique, mastering them perfectly.
The Three Body Technique might not be a highly advanced Ninjutsu, but it was the foundation of many Ninjutsu and had strong practical combat capabilities.
Crucially, it would allow his grades to improve from being the dead last in class to being able to graduate smoothly.
After Takasaki's Chakra volume doubled, his current total Chakra was not abundant, but it could reach the average level in his class.
Of course, he couldn't compare to Naruto.
After all, Naruto had the Nine-Tailed as a cheat within him.
His cheat wasn't bad either.
This was only the first diary entry, and he believed that future rewards would become more and more numerous.
Although he had mastered the Three Body Technique now, he was not yet proficient.
He planned to practice the Three Body Technique more thoroughly today to solidify his foundation.
"Clone Technique!"
Takasaki formed the hand seals again, but found that his Clone Technique could not be smoothly performed. If he forced it, his head would feel dizzy.
"What's going on?"
"Where is the problem?"
Takasaki's mind moved, and he opened his character attribute page.
[Name: Takasaki]
[Age: 12 years old]
[Ninjutsu: Level 1 Clone Technique (1/100) (6 Chakra points), Level 1 Substitution Technique (1/100) (6 Chakra points), Level 1 Transformation Technique (1/100) (6 Chakra points)]
[Chakra volume: 2/20 (1 point recovered every 2 minutes)]
[Stamina: 20 (1 point recovered every 3 minutes)]
He understood.
His Chakra volume was insufficient to perform the Clone Technique again, otherwise, he would fall into a state of shock from Chakra exhaustion, which was life-threatening.
He had to say, this civilian Ninja's body was truly useless.
Since he was idle anyway, Takasaki decided to study his personal attributes.
"I don't understand the content in the first parentheses after each Ninjutsu, but I understand the second one, which means the amount of Chakra required to use that Ninjutsu."
"I just used the Three Body Technique one by one, consuming 18 Chakra points. Now I have 2 Chakra points left, which matches."
"By the way, what do the levels in front of each Ninjutsu mean?"
Takasaki focused his attention on the level of the Clone Technique, and the next second, a system prompt appeared.
[Friendly reminder: The base level for each Ninjutsu you learn is Level 1. You can increase its level by training to gain proficiency. A Level 2 Ninjutsu will consume half the Chakra, and its power will increase by 50%. A Level 3 Ninjutsu's casting speed will double, and its power will increase by 100%. A Level 4 Ninjutsu's power will increase by 200%. A Level 5 Ninjutsu will trigger an additional effect.]
[Each time you use a Ninjutsu, its proficiency increases by one.]
[When proficiency reaches 100 points, the corresponding Ninjutsu can be upgraded to Level 2. At 200 points, it can be upgraded to Level 3. At 500 points, it can be upgraded to Level 4. At 1000 points, it can be upgraded to Level 5.]
Understood.
It's about grinding proficiency, then.
Takasaki wasn't in a hurry to immediately grind proficiency. He planned to write another diary entry to see what rewards he could get.
The problem was that when he picked up his pen to write the second diary entry, the system's voice sounded in his mind:
[Friendly reminder: When the Clone Technique reaches Level 3, the permission to write the next diary entry will be unlocked.]
Takasaki understood.
It turned out that diary entries couldn't be written at any time; there was a Ninjutsu level restriction, requiring the corresponding Ninjutsu level to be reached.
Takasaki could, through his thoughts, see a progress bar on each Ninjutsu level. Currently, the progress bars for all three Three Body Technique were 1/100.
"Grind!"
"It's both to make my Ninjutsu stronger and to unlock the permission to write the next diary entry."
If he didn't become stronger quickly, when the Ninja World War broke out later, Pain could easily smash him to death with a sack of rice.
...
Hyuga Clan's residence.
In the bathroom, Hinata tilted her head, examining the diary in her hand: "Why is Takasaki-kun's diary in my house? And why does my name appear on it?"
