The battle between Amegakure and Sunagakure lasted for an entire night.
Not only were there no signs of the fighting subsiding, but more and more people were appearing in the canyon.
The situation grew increasingly severe.
This situation instinctively led Yuji to guess that Amegakure had launched a large-scale war, utilizing their initial dispersed vanguard to tear open Sunagakure's defensive line at the border... seizing the opportunity to escalate the conflict.
Yuji had anticipated Hanzou would start a war, but not this quickly!
"Amegakure must have already figured out the defensive strongholds on the frontline of the border, but the enemy probably hasn't grasped the specific routes and intelligence in the rear area where we are... Hanzou is likely afraid that Sunagakure is prepared, so he wants to launch a surprise attack."
Yuji and the others moved through the sandstorm. He looked at a hillside not far away where a thick plume of smoke rose from an exploding tag, and thought to himself.
"Yuji, over here!"
At that moment, another Medical Ninja from the squad spotted a casualty and shouted toward him.
Yuji immediately flashed over to check the injured person's condition.
"This one... can't be saved."
After just one look, Yuji said in a low voice.
The Sunagakure Chunin's injuries were too severe. Although he was still breathing... there was no need to waste antibiotics and nutrient fluids.
Before coming to execute the mission, he had thought it was just a regular border patrol assignment, so he hadn't brought many medical supplies. They were intended to last for a mission period of several months, but he hadn't expected the war to be so severe that their reserves were nearly depleted in just one night.
Therefore, Yuji was decisive; he couldn't waste important medical resources, but needed to use the supplies on comrades who could still be effectively helped.
Swish, swish, swish... Just then, several Kunai flew toward them.
They were about to strike the two of them.
At the critical moment, the Chunin escorting them immediately stepped forward and deflected the projectiles.
"Hurry up and go."
The Captain turned back and said to Yuji and the other person.
Several Amegakure Ninja had already appeared ahead.
"Sasori isn't here."
Yuji looked around and found that Sasori was nowhere to be seen.
More enemies entering the rear of the border meant that the enemy numbers were rapidly increasing, making it virtually impossible for them to move around as easily as before.
They encountered enemies almost every few minutes. In this situation, no matter how strong Sasori was, he couldn't look out for them.
The escalation of the war was a test for everyone.
Yuji and the other person immediately turned and ran, disengaging from the fight.
However, the Amegakure Ninja naturally wouldn't let them have their way.
The Chunin leading the team was only one person, but they had run into several Amegakure Ninja.
After one Amegakure Ninja tied up the Captain, the others immediately rushed toward Yuji and his companion.
With his fingertips twitching, the spinning scalpel was instantly gripped in Yuji's hand.
The figure that was running immediately stopped, turned around, and adopted a fighting stance.
"You go."
Yuji said to his teammate, who was also a Medical Ninja.
The latter hesitated for a moment, then quickly retreated.
"For a brat like this to still be alive... he's not simple."
In the blink of an eye, three Amegakure Ninja surrounded Yuji in a triangular formation.
The Amegakure Ninja directly in front of Yuji stared at the youth, his expression surprised.
One must know that it had been over a dozen hours since their Amegakure unit launched their surprise attack into the rear of the border... and their personnel numbers were continuously increasing.
In other words, this battle was no longer suitable for novices to survive.
"A Medical Ninja, huh..."
Another Amegakure Ninja sneered.
In his view, the combat power of Medical Ninja was generally weak. It wasn't that Medical Ninja were incapable, but their abilities were focused on things other than direct confrontation.
"Heh heh."
The Amegakure Ninja let out a sharp laugh, and with a wave of his hand, several Shuriken were flung out.
Yuji quickly dodged.
But as soon as he moved, one Amegakure Ninja flashed behind him.
Yuji immediately swung his blade in a backhand motion.
As if he had predicted the opponent's movement long ago.
The sharp edge of the scalpel was blocked by the enemy's Ninja Tool Gauntlet.
"Quick reaction, huh..."
The man was just about to offer a compliment.
The next second, his eyes widened in terror.
Yuji's seemingly small fist slammed into the Amegakure Ninja's abdomen, causing unbearable, intense pain.
"How is this possible?"
While losing his balance, the Amegakure Ninja couldn't understand how such a small brat could possess this kind of strength.
Wait... it wasn't raw explosive strength!
The Amegakure Ninja realized too late that the youth's punch had struck a vital point in his abdomen, a nerve-sensitive area.
Immediately, before the man could react, Yuji retreated to create distance.
The Amegakure Ninja who had been close behind Yuji tried to pursue, only to find that his lower body had lost all sensation.
He could only watch helplessly as the youth escaped.
Looking down, the Amegakure Ninja realized that his lower back had been pierced by the scalpel, leaving a bloody hole.
An injury to this area seemed to affect his limb control.
"Such a fast blade..."
What was terrifying was that he thought he had only been hit by the youth's fist, yet he hadn't felt anything at all when the blade stabbed him.
The blade was too small to notice, and the edge was thin and light, making it difficult to react immediately even when struck.
"Damn it!"
The Amegakure Ninja cursed aloud, vaguely realizing something.
Then, his legs gave out, and he collapsed onto the ground.
A pool of blood quickly spread beneath him.
"Miura!"
The remaining two Amegakure Ninja were shocked.
They had only seen the youth punch their teammate... why did their teammate suddenly fall?
"Chase him!"
The two gritted their teeth, showing fierce expressions, and seeing Yuji about to run, they immediately followed.
"Watch out!"
However, just as the two chased for about a hundred meters, one Amegakure Ninja's pupils contracted, and he urgently shouted.
But it was already too late.
The other person had already stepped into the small trap Yuji had set up beforehand, utilizing the sandstorm.
Above their heads, an exploding tag blew open a large section of the cliff face, and shattered rocks and dust crashed down.
The remaining Amegakure Ninja watched his companion's figure get swallowed by the falling rocks and dust, and was about to continue forward to chase the youth, because in his mind, the pre-set exploding tag was merely a means for the youth to escape.
Unbeknownst to him, utilizing the drifting dust, a nimble, ghostly figure had already crept up without a sound.
Yuji surmised the opponent's blind spot and did the opposite.
Swish!
Yuji flashed past the Amegakure Ninja and landed in a crouch.
The Amegakure Ninja's pupils dilated. He raised his hand and touched his neck; there was no wound, no blood.
But several seconds later, a bloody gash finally appeared, followed by spraying blood... "You..."
The Amegakure Ninja painfully uttered a single word before falling backward onto the ground.
All three of them had actually been defeated by an inexperienced brat... After killing them, Yuji stood up, didn't spare a glance for the corpses, and immediately jumped away.
"It seems the Amegakure Ninja haven't adapted yet to the weather and environment of the Land of Wind... especially in this canyon terrain, where swirling sand sometimes flies up due to the fierce winds, affecting visibility. There are also many crevices in the protruding cliffs on both sides... allowing for cover and launching attacks. But for myself, the biggest advantage is my young age, which causes enemies to subconsciously underestimate me. Likewise, my small stature makes it easy to hide in the rock walls and difficult to be discovered... it would be much harder for an adult."
Yuji followed the route back to the nearby stronghold.
The strength of these three Amegakure Ninja was far inferior to the one he fought last night... they weren't Amegakure's elite forces.
"Amegakure is attacking fiercely... Sunagakure's reinforcements are likely still en route. This means the Sunagakure Ninja in the rear border area must find a way to hold out until the Village's main force arrives."
The situation was very unfavorable for Sunagakure.
Hanzou's surprise attack plan was having some effect after all.
If the fighting in their rear border area was this severe... one could imagine how intense the fighting smoke must be on the frontline of the border right now.
"However..."
Yuji summoned the system interface, his eyes satisfied upon seeing his surging experience points.
Currently, his positive experience points, which are for healing, had increased from 126 to 307.
His negative experience points, which are for killing, had increased from 0 to 54.
One must know that when he was interning at the hospital, his experience points were usually only 1 or 2. Now, with the battlefield buff, the more severe the injury, the more experience points he gained.
Similarly, the negative experience points gained from killing were also considerable.
The two different types of experience points could be exchanged for different types of abilities and items.
"The medical supplies I brought are almost exhausted after just one night. If I want to save people and gain experience later, I can only rely on pure surgical procedures... and Medical Ninjutsu." Thinking this, Yuji moved his mind, and the system interface changed accordingly.
He scrolled through it.
He saw the abilities he wanted to exchange for.
Which were also the Medical Ninjutsu he could currently afford with his experience points.
Mystical Palm Technique: A-rank Medical Ninjutsu. It vitalizes all cells in a wound, offering remarkable effectiveness in treating external injuries.
Yin Healing Destruction: A-rank Medical Ninjutsu. The user must correctly judge where they will be struck before the opponent attacks and quickly concentrate a certain amount of Chakra at that spot; after being hit, the wound automatically heals.
Removal of Fine Filth Jutsu: B-rank Medical Ninjutsu. A highly advanced technique capable of extracting poisons or removing/transplanting organs.
Resurrection Life Reforming Technique: A-rank Medical Ninjutsu... A quick glance showed that the system displayed a considerable number of Medical Ninjutsu, including Tsunade's original Ninjutsu, the Hundred Seals Technique; as well as the S-rank Ninjutsu Dragon Life Reincarnation, which is the Kusagakure Bloodline Limit ability featured in the movie, and so on.
There was also the One's Own Life Reincarnation that Grandma Chiyo used when saving Gaara... but it required a lot of experience points, more than he could currently afford.
"I'll exchange for the Chakra Scalpel and Mystical Palm Technique first... I have enough experience points, and these two Ninjutsu are quite important."
Yuji checked, and confirmed.
