"I came today to deliver notice," Orochimaru said, arms folded across his chest, "and to give you something else besides."
His slightly hoarse voice fell over the three of them like a blade laid flat against the skin. He looked down at each of his disciples in turn, silently reading their expressions. Sarutobi Enjun was excited. Uzuki Ruri was tense. Uchiha Gen alone lowered his eyes and thought quietly, as if he had been expecting this moment all along.
In truth, Gen had been prepared from the day he graduated. In this era, a ninja's path always led to the battlefield sooner or later. No one truly forged themselves in peace. For people born into a time like this, war was not an exception. It was a gate every shinobi had to pass through.
"Because the village is under tremendous pressure on three fronts," Orochimaru said, "the Third Hokage and the council have decided to incorporate your graduating class into the combat structure. Five days from now, you will assemble and depart for the front in batches."
No one interrupted him. Even Enjun, who had looked ready to blurt something out, held himself back.
Gen's first thought was not fear, but calculation. Which battlefield? Which command structure? With Enjun in the team, and Nawaki's death still hanging over Konoha like a warning no one dared speak too loudly, the Third Hokage would never throw them into the most dangerous meat grinder without reason. Not unless something had gone terribly wrong.
"Orochimaru-sensei," Gen asked, lifting his head, "which front are we being assigned to? And which unit are we joining?"
"The Land of Rain." Orochimaru answered without hesitation. "You'll be attached to the strategic support force. You won't be stationed at the very front, but it is still the front line. The danger there is not less than it is inside the village. When I am absent, Gen will hold tactical command of your team and coordinate with other squads."
Ruri's fingers tightened at her sides. Enjun straightened slightly, his expression turning more serious. As for Gen, the answer only confirmed what he had suspected. They would not be used as expendable shock troops, but neither would they be sheltered. A support force at the Rain front still meant blood, ambushes, supply lines, and sudden death under gray skies.
Orochimaru formed a seal with one hand. A snake appeared, slithered forward, and spat out a scroll onto the ground. He bent to pick it up and held it out toward them.
"This is a contract scroll from Ryuchi Cave," he said. "Use your blood to leave your names on it. Once you do, I will notify the Snake Sage there and have the Reverse Summoning Technique bring you in."
At that, even Gen's expression changed slightly.
Ryuchi Cave.
Mount Myoboku. Shikkotsu Forest. Ryuchi Cave. Of the three great summoning lands, Ryuchi Cave was easily the least gentle of them. The toads of Mount Myoboku were eccentric, but still belonged to the righteous side of the world. The snakes of Ryuchi Cave were different. Cruel, predatory, arrogant—some of them were less like summoning beasts and more like old monsters wearing serpentine skin.
Orochimaru seemed to understand what all three of them were thinking. His golden eyes narrowed a fraction.
"Before you go, remember this clearly. Do not trust what you see there. Stay vigilant at all times. That place is not friendly to those who lack willpower, intelligence, or caution. Once you step into Ryuchi Cave, it becomes very easy to lose your way—and much harder to return."
The warning was not delivered with emotion. That only made it more convincing.
Compared to Mount Myoboku or Shikkotsu Forest, the serpents of Ryuchi Cave were far more vicious. Even those who survived the trial did not necessarily leave with warmth in their hearts. Gen had no doubt Orochimaru was not exaggerating. If anything, he was probably understating the danger for Enjun and Ruri's sake.
Still, danger or not, an opportunity like this was impossible to dismiss. A true contract with one of the three great summoning lands was a foundation powerful enough to change a ninja's path for life.
"If you pass the Snake Sage's test," Orochimaru continued, "you will be qualified to form a true contract with Ryuchi Cave. But unlike ordinary summoning contracts, signing the scroll does not mean the snakes there will serve you obediently."
He drew out a second scroll and held it between two fingers as he spoke.
"Common snakes are simple enough. They can be tamed by conventional methods. Or, as I have done, you can modify the body to become more snake-like. That increases flexibility, elasticity, physical resilience, and your ability to intimidate and command lesser serpents. But the larger snakes with real strength are different. To win them, you must defeat them yourself."
He let the words sink in before adding, "And even if you defeat them, the strongest among them may still refuse to submit. At best, they will accept an equal contract. To command them, you will have to offer a price."
Then he handed them the second scroll.
"This contains the formula and process for the snake-body modification."
The scroll passed from hand to hand. Ruri opened it first, then Enjun, then Gen. Inside were dense notes on several stages of transformation—medicinal materials, preparation methods, bodily adaptation, risk factors, and the signs of failure. Even a quick glance was enough to reveal how complicated the procedure was.
It was not some crude surgery or reckless forbidden technique. It was painstaking. Layered. Expensive. Orochimaru had clearly perfected it over many iterations, and not alone.
"The early stages are manageable," Orochimaru said. "They require resources, but not an impossible amount. If your families are willing to support it, they can be completed in time. The real difficulty comes later. This technique places demands on chakra quality, on pain tolerance, and on the ninja's own will. If your foundation is not good enough, the modification will fail."
His gaze lingered for a heartbeat on each of them in turn. "Even I have not completed the process fully."
That line carried more weight than any threat could have. Orochimaru was not the sort of man who admitted limitation casually. If even he said the technique was not yet complete, then the road ahead was not something any of them could treat lightly.
Gen studied the formulas more carefully as the scroll sat in his hands. He could already see the logic in it. Increased elasticity. Improved flexibility. Better resistance to poison. Stronger explosiveness and agility. It was exactly the kind of brutal, efficient enhancement one would expect from Orochimaru—practical, unnerving, and extremely useful.
But it also carried Orochimaru's signature danger. Not the obvious kind. The quieter kind. The kind that smiled at you and handed you strength one layer at a time until you had already stepped too far to retreat.
He rolled the scroll back up and passed it on without saying anything.
"It's almost time," Orochimaru said suddenly.
Ruri blinked. Enjun frowned. "Time for what?"
Gen felt it before Orochimaru answered. A strange tug pulled at his chakra and body at the same time, like a hook catching beneath his ribs. Reverse Summoning.
"Ready yourselves," Orochimaru said. "If you hesitate once you arrive, you may not get a second chance."
The pull intensified immediately after that. It was not a request. It was a force.
"Orochimaru-sama, farewe—"
The rest of Enjun's words vanished into a burst of smoke.
Gen's own body lurched. He resisted instinctively, and for the briefest instant, he felt the difference between himself and his teammates. His strength was higher now than theirs. His chakra was denser. For a tiny moment, he could actually push back against the call. Then the force on the other end swelled sharply, and his resistance shattered.
"Bang!"
White smoke burst around him. When it thinned, Uchiha Gen already had one hand on the hilt of his ninja sword.
Fog. Thick, cold, and unnatural.
He scanned his surroundings at once. Ordinary sight was nearly useless here. He opened the Sharingan without hesitation, the single tomoe in each eye spinning into place, and at the same time spread his sensory ninjutsu outward in a thin, cautious wave.
Within moments, he located Sarutobi Enjun and Uzuki Ruri not far away. They had arrived slightly earlier than he had, and the difference irritated him less than it interested him. It meant exactly what he had suspected. The stronger the target, the more difficult reverse summoning became. He had actually forced the summoning side to exert more strength before it dragged him all the way through.
That realization was useful—and a little chilling.
If the one calling them had been an ordinary snake, perhaps he could have resisted longer. Perhaps even broken free altogether. But the presence hidden in this fog was no ordinary serpent.
The Snake Sage of Ryuchi Cave.
A creature old enough to stand above the other snakes, old enough to summon them directly despite distance and resistance, old enough that even Orochimaru himself had not formed an equal contract with it. Compared to Gen and the others, it was less a living thing than a force of nature wearing scales.
Somewhere in the mist, it was watching.
Gen could not see it. He could not sense its exact location, either. That alone told him enough. The fog did not merely obscure vision. It concealed intent. Aura. Movement. If the Snake Sage wished to remain hidden, then three genin were not going to uncover it by force.
Orochimaru's warning echoed in his mind with renewed clarity. Don't trust what you see. Stay vigilant. That place is not friendly.
Gen exhaled slowly and adjusted his footing, angling his body so he could reach both his sword and his tool pouch without hesitation. Beside him, Enjun had already gone stiff, jaw clenched despite his attempt to look brave. Ruri, for all the tension in her face, had not lost her composure either. She was watching the fog just as carefully as he was.
Good. No one had panicked yet.
The fog moved.
Not much. Just enough to make the world feel alive in the wrong way. A shift in the whiteness. A drag of something vast through damp ground. A whisper of scale on stone. Every sense in Gen's body tightened.
He had entered the place once in memory, through the original story and everything he knew from the game systems of his previous life. But memory was not experience. Reading about monsters and standing inside their den were two very different things.
Still, fear was only useful if it sharpened thought. So Gen held onto it and forced it into order.
Ryuchi Cave was not a place for hesitation. It was a place that measured appetite, nerve, cunning, and strength. The snakes here did not care about village titles, clan prestige, or the softness of children. If they found weakness, they would bite. If they found confusion, they would coil around it until the bones cracked.
And yet Gen's heart beat a little faster for another reason as well.
Opportunity.
A true contract with Ryuchi Cave. Snake-body modification. Larger summons. A summoning land that answered to power rather than sentiment. Everything about it was dangerous. Everything about it was useful. In a world heading deeper into war, usefulness mattered more than comfort ever would.
He tightened his grip on the sword hilt, then finally spoke, keeping his voice low and steady so it would not carry carelessly into the white around them.
"Stay sharp," he said to his teammates. "Don't trust the fog, and don't trust anything that tries to rush you into a decision. If something appears, we observe first."
Enjun swallowed, then nodded. Ruri gave one quick, wordless tilt of her chin.
Good enough.
The mist thickened again, and the air seemed to grow colder around their ankles. Somewhere ahead, something breathed—slowly, deeply, as if it had all the time in the world.
Uchiha Gen let the Sharingan drink in every ripple it could catch, and let his perception spread just a little farther despite the danger of overextending himself.
Whatever trial Ryuchi Cave had prepared for them, it had already begun.
