"Fire Release: Great Fireball Technique!"
Uchiha Ryun swiftly formed hand seals, launching a massive fireball directly into the Rain-nin camp. Alongside several Konoha jonin, he charged into the enemy camp, his skills gradually honed through intense combat. His mastery of various abilities became increasingly fluid.
The battlefield was an excellent place for tempering oneself, but it was also an extremely perilous zone of death. After exhausting his strength to kill a jonin, Ryun suffered a deep slash on his left arm from the enemy's tanto.
The wound itself wasn't severe, but the real danger lay in the fact that the blade was coated with salamander poison. Within a minute of being injured, Ryun immediately realized the gravity of the situation.
Clenching the chakra blade between his teeth, he used his right hand to forcefully squeeze out a large amount of poisoned blood. He then applied Chidori Current to the wound, intending to use the high temperature to neutralize the salamander poison.
Salamander poison was an animal-based toxin, composed of various proteins and enzymes, similar in composition to snake venom. This type of poison was highly susceptible to heat. Ryun's chakra current could disrupt the toxin's activity, significantly reducing its potency.
Once his arm showed signs of charring, Ryun switched to medical ninjutsu to treat the wound. However, just as he was healing himself, a Rain-nin chunin charged at him with a tanto raised high.
Ryun coldly watched his approach. The enemy locked onto him, swinging his tanto in an attempt to decapitate Ryun.
At the critical moment when the chunin believed he was about to succeed, the young boy's eyes suddenly glowed red. The crimson three-tomoe Sharingan appeared without warning.
The three black tomoe trembled faintly, the pupils completely focused on the chunin. The moment the eyes manifested, the Rain-nin chunin froze mid-action. His mind was filled with nothing but those bright crimson three-tomoe Sharingan eyes.
In reality, the Rain-nin chunin collapsed straight to the ground. Ryun didn't spare him another glance. His trembling hand reached for a pouch, retrieving a small vial of antidote. After removing the cap, he drank the green liquid in one gulp.
This was the latest antidote developed by Tsunade. The supply was limited, and Orochimaru had acquired some, giving Ryun a small vial for emergencies. Ryun never expected he would need to use it so soon.
Salamander poison was terrifying. Ryun personally experienced its lethal effects. Despite his quick response, a tiny amount of the toxin had already spread, and the negative symptoms of poisoning couldn't be eliminated in a short time.
At this moment, he exhibited many signs of poisoning: accelerated heartbeat, body tremors, excessive saliva production (commonly known as drooling), and difficulty breathing.
Ryun picked up the chakra longsword and plunged it into the fallen chunin's heart, ending his life. After this, he found a relatively safe corner, sat down, and began panting heavily. He accelerated the flow of chakra in his body, trying to quickly counteract the effects of the poison.
At this point, he was no longer fit for high-intensity combat.
Besides, he wasn't the type to sacrifice his life for Konoha. Being poisoned and injured meant he needed to rest. After all, with only a meager monthly salary, why should he risk his life?
After resting for nearly ten minutes, the battle gradually came to an end.
"Burn all supplies on-site. The entire unit will withdraw in three minutes. No delays!"
An elite jonin issued clear orders.
They couldn't take so many supplies with them. Moreover, Rain-nin reinforcements had already begun arriving. If they didn't retreat now, getting entangled would be fatal.
The real Hanzō of the Salamander might already be on his way. If they were caught by him at this critical moment, these Konoha ninja would either die or suffer heavy losses.
No matter how valuable the supplies were, they wouldn't take them or linger here.
A small, blockaded country like the Land of Rain might lack supplies, but the Land of Fire was prosperous and resource-rich. They weren't short on materials.
Ryun patted his cheeks to stay alert. He had mostly recovered by now. Sheathing the chakra longsword on his back, he prepared to "clock out" on time.
After returning to the base camp, Ryun removed his blood-stained armor and collapsed onto a moisture-proof mat without even bothering to bathe, falling into a deep sleep.
The effects of the salamander poison hadn't completely dissipated. His body's struggle against the residual toxins left him exhausted. He needed ample rest to fully recover.
In his drowsy state, he felt someone removing his clothes and wiping his body with a warm towel. Ryun could vaguely sense his surroundings, but opening his eyes completely was difficult.
Through his half-lidded gaze, he saw the gentle Tsunade—and her signature ample bust.
"How is he now?" Orochimaru's hoarse voice sounded quietly.
"Starting to run a high fever. It's his body fighting the remaining toxins. It shouldn't be a major issue," Tsunade replied.
The wound on Ryun's arm had only been roughly treated earlier. After Tsunade arrived, she fully healed it using the Mystical Palm Technique.
The high-level medical ninjutsu—Mystical Palm Technique—healed wounds at the cellular level, leaving no scars behind.
"This kid is really tough. Even after being poisoned by salamander venom, he endured until returning to camp without making a sound or letting anyone know. If Orochimaru hadn't come looking for him, no one would have realized he was poisoned," Jiraiya couldn't help but praise.
After handling the aftermath of the battle, Orochimaru came to check if his beloved student was injured. Seeing Ryun sleeping without bathing and unable to be woken, he immediately sensed something was wrong and hurried to fetch Tsunade.
Through the blackened arm, the missing antidote, and the feverish symptoms after detoxification, Tsunade confirmed he had been poisoned by common salamander venom.
What surprised her was how well Ryun had handled it on his own. The salamander poison had almost no major effect on him, a fact that left Tsunade deeply impressed.
"Even if I hadn't come, this kid would have been fine after waking up. He already neutralized the salamander poison himself. He might be the fastest and most effective among all poison victims in handling it."
"What a clever little guy!" Tsunade chuckled, pinching his handsome cheeks.
Ryun's method of using electricity to disrupt the poison's activity left even Tsunade in admiration. For someone so young to independently resolve such a deadly crisis, this boy's adaptability was frighteningly strong.
