Tsunade had just become the Hokage after the death of her teacher.
Although she didn't respect him now, especially after she got to know about how her clan was sent to their death, along with her brother Nawaki.
He knew well that he was not ready for it, along with that he could easily dodge something as simple as a landmine.
But just after she held office, Sauske, the last Uchiha defected.
She had still not completely stabilized her position and this happened.
This made her more frustrated as he even went to the person who destroyed Konoha.
Konoha's higher power was already spread thin after the attack, and now failure to take back Sauske was just more to the pile of frustration she had especially due to the elders.
She was about to go out drinking after some more of signing documents, and a research paper regarding chakra extraction technique was interesting to say the least.
The current widespread chakra extraction technique taught in Konoha was made by her second grandpa.
Along with growing up under the man known for his forbidden techniques, she certainly had high standards.
When seeing that the report was of a chunin, her expectations dropped.
She had nothing against people of lower strength, but it was difficult for a chunin to make an improvement to the current technique to say the least.
So one can imagine her surprise when the research written was thorough, along with the technique being modified in a way she never though before.
Completing a cycle as is nature's rule huh. This is really an interesting concept, plus, his research ability seems very good.
If he can produce this level of skills even if they are up to chunin level, it will fundamentally increase the power of Konoha.
The more she thought, the more she was surprised by the simple concept used in the technique, but at the same time very unique and different perspective.
She then decided to try it for herself to test if it was really as good.
It was easy to start and understand so she was sure that even if unsuccessful, it will not harm her, especially with her chakra control and strength.
This... This is really much better. My body also feels much more energetic and feels as if rejuvenated.
I need to research and check this out soon. If it is really as good as I think, this will be a really big boon.
"Shizune, I am taking a break and doing some research. Don't let anyone disturb me. Especially those old fools."
"Ahaha... Yes Tsunade-sama."
Then she stormed off to her own lab, with the scroll.

The next day, at the Hokage office.
"Shizune, call Hiroshi Daigo from research department here."
"Yes Tsunade-sama."
---
I was roaming around Konoha, looking for relaxing spots for me to laze around when I am not researching, and finding new food spots which suit my taste.
Suddenly, Shizune and an anbu with a fox mask appeared on front of me.
"You are called by the Hokage to the office."
"Okay. Let's go."
Then we shunshined straight to the Hokage office from the forest behind Hokage mountain.
---
Me, Shizune, and Tsunade were the only ones in the office, at least visibly.
Not gonna lie, being with beautiful women never gets easier especially if you are a two life virgin and the said beauties are much stronger than you.
After a nervous stating contest between me and Tsunade, I gave I'm because I am uncomfortable under that piercing gaze.
I totally get how people sweat bullets in anime now. This is really intense.
"Um... Tsunade-sama, can you tell me why I am here?"
I was on my break! My hard earned two day break that I get after every technique submission.
I will not work overtime! I want to relax, not become a slave!
"The technique you created, for chakra cultivation as you call it, is very good, and easy to learn. It will be Konoha's new standard technique. You made a good contribution, so you will be rewarded 200,000 yen. Keep it up."
"Thank you very much Tsunade-sama, I only did it for the village."
Yes! My bonus is here! I can be financially independent soon if this continues. Woohoooo!
Was Hiroshi's internal monologue, while keeping a straight face.
"Okay. Keep up the good work. Even if your strength cannot improve much, you should focus on what you can do as no contribution is small."
"Yes Tsunade-sama."
Then I left to continue my exploring if good good and nice relaxing spots.
"Tsunade-sama, why did you take it so seriously? Is there anything that is special in the technique? As there have been many revisions to it since it was created but not all of then succeeded."
"This technique can help speed up chakra regeneration, increase the upper limit of chakra capacity, can be used by everyone and no matter how long they use it, it will not be harmful for their body.
It indirectly increases chakra control to be better, makes body adaptable for chakra usage quicker, along with anyone no matter how little chakra they have, can practice it easily.
The surprise in all this is that it doesn't tire out the body or eat up the potential, instead it increases it although only a little, along with increasing the vitality in the body bit by bit and passively purifying the bloodline.
Although in the initial stages it isn't noticeable, but what about after 5 years, 10 years, 15 years? This can qualitatively increase combat power of every Ninja in our village.
Even he might not have realized or noticed that as made it.
It also increases metabolism, gives better skin, has less chance of the user ever getting fat.
The only side effect is increased appetite.
Now what do you think Shizune?"
"Wha... This should be a top secret matter Master Tsunade."
"That is also what I think, so I will say that I developed the technique. Also, send a message to Hiroshi Daigo that all further techniques he develops should be directly submitted to me. If he needs some research materials, he can ask me directly provided he state the purpose."
"Yes, Hokage-sama."
