Chapter 4: Five-Second Man
"Yes, war is terrible."
Kosuke sighed, as if recalling something.
"It's a good thing you're a medical ninja now, so you don't have to worry about that anymore."
Generally speaking, medical ninjas choose to work at the Konoha Hospital.
Even if war breaks out again, the medical ninjas' mission is to provide support from the rear.
"On the battlefield, I witnessed my teacher and comrades die because they didn't receive timely treatment, which is why I wanted to become a medical ninja."
"Of course, it's also because my talent in combat isn't very good."
Looking at the sad and dejected Aosui, Kosuke felt even more empathetic.
Both of them had experienced the pain of losing comrades.
"Everyone has their own strengths. I believe your teacher and comrades in heaven would also be proud of you today."
"I hope so. But I won't give up on continuing my training. I'll work hard to become stronger so I can better protect everyone in the village!"
Having grown up in Konoha since childhood, Aosui naturally had feelings for this hometown where he had lived for eighteen years.
But he wasn't so benevolent as to want to protect everyone.
He wasn't some Great Love Immortal Venerable.
He just said that to gain more approval from Kosuke, and then he would have a reason to continue learning swordsmanship from Kosuke.
Even with the system, he couldn't truly stop cultivating himself.
Strength was the fundamental key to survival in the ninja world.
He had no choice before, but now he only wanted to secretly develop and quietly grow stronger.
"Good child. When I'm discharged from the hospital, you can continue training with me. It'll be a good chance for me to see if your swordsmanship has regressed."
Before Aosui could even speak, Kosuke proactively suggested it.
Aosui was pleasantly surprised.
"Really?"
"Of course, it's real."
"Thank you, Uncle Kosuke, but for now, you still need to rest well."
Back in his office, Aosui began to study the Water Release: Water Dragon Bullet he had just acquired.
This was a B-rank Water Release ninjutsu, and also the ninjutsu with the most hand seals in the ninja world, totaling 44 seals.
Of course, there was also a simplified version.
The Second Hokage, Tobirama Senju, who was highly skilled in Water Release, only needed three hand seals to use this technique.
Later, Tobirama Senju taught this technique to Maruboshi Kosuke.
However, he couldn't match Tobirama Senju and couldn't perform it with just three hand seals, but he only needed six hand seals.
And what Aosui received was the six-hand-seal version of the Water Dragon Bullet.
"It seems the ninjutsu rewarded by the system should be what the treated object itself mastered."
From this point, Aosui gained a greater understanding of the system's reward mechanism.
"And my luck is pretty good too; the first release technique I was rewarded with is compatible with me."
Aosui had once tested his chakra nature, and it was indeed water nature.
Under the guidance of his instructor, he naturally underwent training in water release nature transformation.
However, due to his less than ideal talent, he had never been able to complete this training, and as a result, he had yet to learn any water release ninjutsu.
But Aosui had never stopped training, and not long ago, he finally succeeded in mastering the nature transformation of Water Release.
This Water Dragon Bullet came just in time.
Of course, if the system had rewarded him with a release technique of another attribute, Aosui would still be able to use it.
Because the jutsu rewarded by the system was directly implanted.
It felt as if he had personally trained for several years.
However, since he hadn't truly mastered the corresponding nature transformation, his release of ninjutsu would definitely not be as fluid as Water Release ninjutsu, making it easy to expose weaknesses in combat.
And in ninja combat, even a one-second flaw is enough to decide the outcome.
That's why Aosui felt fortunate.
Next, Aosui completed five more treatments, acquiring a total of two white orbs and three blue orbs.
The two white orbs increased his chakra by a total of 30 points.
The three blue orbs increased his chakra by a total of 200 points.
Adding the previous 90 points, he had increased his chakra by a total of 320 points today, reaching 820 points.
He also gained one genjutsu and one ninjutsu.
After work, Aosui went to his usual training spot.
He quickly formed six hand seals, then released Water Release: Water Dragon Bullet.
A stream of water was spewed from his mouth and transformed into a giant water dragon. Under Aosui's control, the water dragon roared and crashed into a large tree.
Bang!
After an explosion, the large tree, which required two people to embrace, was instantly snapped in half.
Such terrifying power made Aosui very satisfied.
Now he finally had a powerful enough killing move.
The only problem was that he couldn't openly use the Water Dragon Bullet yet, as it was a B-rank Water Release ninjutsu.
Fortunately, it wasn't a big problem for Aosui; he could just ask Kosuke for guidance later.
Since he had the Water Release nature, the reason was also legitimate.
"But it truly lives up to its B-rank ninjutsu status; just that one use almost completely depleted my chakra."
"Indeed, I must continue to increase my chakra, otherwise I'll truly become a five-second man."
Since there was no target, Aosui decided not to test Demonic Illusion: Tree Binding Death.
After continuing his training for some time, he finally finished and went home.
As an orphan, Aosui grew up in the Konoha Orphanage until he graduated and became a ninja, gaining independence.
And a few years later, with the money he earned from missions, he acquired a home of his own on the outskirts of Konoha.
With his genin-level financial capabilities, he naturally couldn't afford a house in the main city area.
As for renting in the main city area? Aosui felt it wasn't necessary.
Anyway, with a ninja's leg strength, it wouldn't take long to run across the entire Konoha.
Commuting to and from work every day would only take a few extra minutes.
The night passed without incident, and morning arrived on the second day.
Aosui arrived at Konoha Hospital full of enthusiasm, not at all like a typical worker.
"Lord Hirakawa, a patient needs your treatment."
Just as Aosui was immersed in his work, Tsunade, who was still sleeping in the Senju clan compound, was woken up by Kushina.
"Lady Tsunade, don't forget you have to go to Konoha Hospital today to guide Aosui."
"It's only a little past nine, isn't it?"
Although she said that, Tsunade still got out of bed.
By the time she arrived at Konoha Hospital, it was already past ten.
As for Kushina, she didn't come along because she had to learn sealing jutsu from Mito.
"Lady Tsunade!"
Upon seeing Tsunade, Fukada Minako was very surprised and excited.
It had been a year since she last saw Tsunade at Konoha Hospital.
As a result, as the deputy head of the medical department, she had to take on the responsibility of managing Konoha Hospital.
And this was supposed to be Tsunade's job as the head of the medical department.
"Long time no see, Minako. Do you know Hirakawa Aosui?"
Tsunade got straight to the point.
