"Not much experience points..."
After killing several Hidden Mist Ninjas, Yubi opened the System panel and glanced at it.
Although he adhered to the philosophy that even a mosquito's leg is meat and had been accumulating negative experience points, he realized during the Late Stage of the battlefield against Iwagakure that as his strength increased, the rewards for killing ordinary enemies were decreasing.
Of course, as long as there was enough time, the small amounts would still become quite considerable once they added up.
It was just that these small skirmishes weren't as easy to 'earn' from as a large-scale battlefield.
If he killed all the enemies himself... Pakura and the others wouldn't have anything to do.
The main goal of this mission was to train and temper them.
Coincidentally, Yubi also wanted to take this time to properly Cultivate his Hand Seals and research some Ninjutsu, so he was content to be a hands-off mentor, allowing the four students to act independently.
Otherwise, trying to train them, complete missions, and study all at once... time would be a bit tight.
He couldn't quite manage it all... Later, the five-man squad's daily missions turned into Yubi always hiding in the shadows with a book or notes in hand, while Yashamaru and the other three searched the Hidden Mist activity zones according to the map's intelligence.
Even if a battle broke out, Yubi wouldn't intervene immediately.
Even when several of them were wounded, he didn't make a Move, letting the students personally go through and experience life and death.
With his current abilities, even if the four of them were heavily injured, as long as it wasn't life-threatening, he could save them.
If it were life-threatening, then he would have to use his 'trump card'.
Under normal circumstances, Yubi wouldn't let such a thing happen.
This ability of his wasn't a conventional Medical Ninjutsu... but a means converted into Ninjutsu that he had exchanged from the System using positive experience points after being busy on the battlefield against Iwagakure for over a year.
Saving Sakamoto was also thanks to this ability.
Originally, Yubi intended to purchase Tsunade's two S-rank forbidden techniques, namely Creation Rebirth and the Hundred Seals Technique.
However... he discovered an ability that covered almost all the effects of both forbidden techniques, and it could be applied not only to himself but also to others.
In terms of price, it was also cheaper than both Ninjutsu combined.
It was extremely cost-effective.
So, he decisively changed his mind.
He would no longer learn Tsunade's two forbidden techniques.
This also left some surplus positive experience points.
One must know that on the battlefield against Iwagakure, the subjects he had to treat weren't just his squad, but the wounded from the entire main force... Therefore, the positive experience points he gained over that year were particularly substantial, but... his newly acquired ability was also quite Heaven-Defying; although it was cost-effective, it was also staggeringly expensive.
It originated from the Advanced technique of Jujutsu Sorcerers in Jujutsu Kaisen, the Reverse Cursed Technique.
It could promote cell regeneration and repair damage... when operated to the extreme, even if brain tissue was destroyed, it could be restored.
Of course, the specific effects it could present depended on personal strength.
In the original work, although some characters could use the Reverse Cursed Technique, they could only use it on themselves and couldn't treat others.
But there were a few exceptions.
Yubi not only purchased the Reverse Cursed Technique... but also unlocked the subsequent effect of being able to use it on others.
Like Blood Release, this ability required him to slowly develop and improve it later... or, he could directly spend experience points to max it out, but the price... was out of reach for now.
With the Reverse Cursed Technique, it meant that as long as it wasn't an extremely 'dominating' power that caused massive destruction and damage to his physical body in a short time—such as being cut in half at the waist or having his entire head destroyed—he could drive the Reverse Cursed Technique with his remaining consciousness, unleashing terrifying vitality and self-healing properties.
Another point... even if this ability was assimilated into a Ninjutsu, it was a seal-less Ninjutsu that didn't require Hand Seals... it could be activated at any time.
One could see how broken it was... otherwise, Yubi wouldn't have painfully spent all the experience points he had earned over a year of risking his life.
Mastering the Reverse Cursed Technique didn't mean he was absolutely safe; there were still many ways to kill him in the Ninja World... besides, some special Bloodline Limits or individuals also had similar Moves.
For Yubi, it just meant he could have relatively less pressure and be more at ease when facing enemies or dealing with troublesome situations.
However, if he ran into some truly tough characters... that would be another story.
Yubi only used the Reverse Cursed Technique once on Sakamoto and wasn't worried about this ability being exposed because... including Yashamaru, with their vision and knowledge, they couldn't see anything amiss at all.
Relying solely on his pure medical skills and several other types of Medical Ninjutsu, as long as the students' injuries weren't too severe, he was confident in making them recover in a short time.
Therefore, regarding the mission content, he completely let the few of them do as they pleased, only providing some combat ideas or suggestions.
In Yubi's eyes, what the few of them needed to hone most right now, besides practical combat experience, was clearly their mindset.
The psychological fortitude of several students was a bit too weak.
To be honest, this training method of his was a bit 'cruel' for the other three besides Yashamaru.
But Pakura, Fukushima Taki, and Sakamoto adapted well.
The reason was simple: Yubi's medical skills gave them a full sense of security.
Even if they were injured, they could receive excellent treatment... and recover quickly; they just had to endure some physical pain.
This also allowed them to let loose and fight the enemy.
At the same time, it was the best way to temper their fighting will.
The best way to solve fear... is to face it, keep it company, and make this feeling the norm.
Everything else would then follow naturally.
This was Yubi's teaching method... Swoosh, swoosh, swoosh... One night, in a depression, Yashamaru was leading Pakura and the other two in a desperate escape, moving at high speed.
His expression was exhausted, and he was covered in sweat.
Beside him, Pakura and the other two were also wounded.
The situation was not optimistic.
During the day, they had discovered a Hidden Mist hiding spot nearby, but they didn't act immediately. Instead, after careful observation and gathering information on the enemy, they prepared to launch a surprise attack at night, taking advantage of the darkness to catch the opponent off guard.
But the plan was good... when it came time to actually do it, the situation was different again.
They thought there were four enemies, and there were four of them... plus they had gained some experience from fighting the Hidden Mist during this period, so they thought about feinting to the east and attacking the west, using one person to draw the opponent's attention and disperse the target personnel, then taking them down one by one.
As a result... luring the tiger away from the mountain failed, and the enemy even discovered the three who were hidden.
Not only that, there was actually another Hidden Mist squad active around here that they hadn't searched out.
This time, the consequences... went without saying.
The four began to flee in a sorry state.
But they could never shake the opponent.
"Where's the teacher... isn't he coming out yet?"
Sakamoto panted heavily while running wildly, looking blankly at the dark night around him.
Being Yubi's student was both a blessing and a torment.
The blessing was that the sense of security was total; they weren't afraid of dying.
The torment was... every time they were in such a critical moment, they couldn't tell exactly when Yubi would make a Move, let alone where the teacher was hiding.
"You guys go first, I'll cover the rear!"
The only girl in the team, Pakura, gritted her teeth, stopped her pace instantly, turned around, and formed Hand Seals with both hands.
"Scorch Release: Steaming Swelter."
After speaking, several fist-sized fireballs appeared around her. They didn't look like ordinary flames, but more like a pure fire energy.
Formed from the Fusion of wind and fire Chakra natures.
Several fireballs flew toward the pursuing Hidden Mist Ninjas, not hitting their bodies, but just exploding in the space where they were.
In an instant, the Hidden Mist Ninjas felt a wave of dry heat fill the surroundings, rushing toward them.
Unlike the direct destruction of a typical Fire Release, this wasn't simple burning, but more like roasting under high temperature.
Even their breathing caused intense pain in their lungs, and as soon as their eyes touched the air, it felt as if the moisture in their sockets was evaporated in an instant.
"A Bloodline Limit... kill her!"
Fortunately, this young girl's Ninjutsu power wasn't that great; although it made the Hidden Mist side feel uncomfortable and pained, it was bearable for them.
The Hidden Mist captain stared intently at Pakura and said sharply.
Immediately, several Kunai with exploding tags attached fell toward Pakura's position.
Detonating the ground.
The range of the explosion was large, and Pakura couldn't avoid it in time; although she tried her best to dodge, she was still sent flying by the blast.
"Pakura!"
Yashamaru leapt into the air and caught Pakura, landing on the ground.
In just that blink of an eye, six Hidden Mist Ninjas had already surrounded the four in the field.
"Interesting... the Hidden Sand Village is actually willing to let such a young Bloodline Limit Ninja out to do missions."
The Hidden Mist leader said coldly, "This little girl must be captured and taken back; the other three can be slaughtered!"
They had already injured these four Hidden Sand Ninjas during the pursuit, and looking at their state, it was impossible for them to mount any decent counterattack.
"Teacher... Teacher!"
Sakamoto licked his dry lips and shouted loudly.
This time, it wasn't just a crisis... it was truly possible that their lives would be lost.
If Teacher Yubi didn't make a Move soon, they were going to die.
"Teacher?"
The Hidden Mist captain heard this and gave a cold snort.
He wasn't surprised... it seemed to be a rookie squad from the Hidden Sand Village out for training on this battlefield.
No wonder... he was wondering how the Hidden Sand Village could be so stupid as to let someone with a Bloodline Limit come here to die.
Using them as training targets?
Seeking death!
"Teacher..."
After shouting a few times, Sakamoto's voice even carried a bit of a sob.
"Stop yelling, I heard you... I heard you."
"Sigh... it's not a life-or-death moment yet, don't be so scared..."
Suddenly, a figure dashed from the shadows and instantly landed in the field.
The speed was so fast that the expressions of the Hidden Mist Ninjas changed.
Then, looking closely, their eyes were filled with surprise.
They thought the person who came would be some expert from the Hidden Sand Village.
"What... another youth?"
This guy is the leading teacher?
The Hidden Mist leader remained silent.
Coming beside the four, Yubi sighed and stared at Sakamoto, "This time there are only slightly more people, you've clearly fought so many times, you need to be braver."
"Teacher Yubi... no, I really don't have any stamina left."
Sakamoto explained.
"If you don't push yourself, how will you know where your limit is? Never underestimate yourself."
Yubi smiled.
He actually started teaching his students right in front of the Hidden Mist Ninjas.
Yubi?
"Hmm?... No... this guy looks a bit familiar..."
Suddenly, the Hidden Mist captain's pupils constricted.
As if he finally remembered... who the youth in front of him was.
"The Hidden Sand Village's Blood Medic... Yubi!"
"Retreat!"
The Hidden Mist leader's voice suddenly carried a hint of panic, no longer as calm as before, as he immediately shouted.
If it really was that guy... the six of them were no match for him at all.
Rumor had it that the Blood Medic Yubi went deep into the Iwagakure combat zone alone and killed nearly a hundred Iwagakure Ninjas by himself.
He was beyond terrifying!
Swoosh!
The other five Hidden Mist Ninjas received the order, their hearts trembling, and they retreated explosively in an instant.
But only the Hidden Mist captain stopped in place. It wasn't that he didn't want to run, but he suddenly found that his torso was out of control.
Yubi, who was clearly in front of him just a second ago, was now... eerily standing beside him.
Ninjutsu: Body Pathway Derangement.
Converts Chakra into electrical waves, interfering with the brain's transmission of commands to the body, making the target unable to control their body normally.
"Retreat?"
Yubi curled his lips, "That won't do... You are enemies. If I just let you leave like this, I would be a very neglectful teacher... Besides, you even injured my students."
"By the way, am I that famous now? This is the first time I've been recognized... Haha."
