153 - The First River War

Chapter 153 — The First River War

The morning after the flood was spent assessing the damage.

The settlement had survived, but the road connecting it to the neighboring towns had been partially destroyed, several buildings near the river had suffered structural damage, and the original riverbank no longer existed in some places. Fortunately, the evacuation had been completed before the worst of the flooding, and the casualties remained limited to several injured workers and a few damaged vehicles.

For the Association, however, the more important discovery was what had happened upstream.

The monsters had not been attacking the settlement.

They had been trying to escape the changing river.

That distinction changed the mission plan.

Instead of sending the team directly toward the dungeon, the South American authorities requested that they accompany a group of local Awakeners farther upstream. Their objective was to determine whether the creatures were continuing to move away from unstable sections of the river or whether another change was approaching.

Subin, Yerin, Min-seok, Jae-hyun, Ara, Ethan, Liu Wei, Mateus, and Camila departed shortly after sunrise.

They traveled by vehicle until the road ended and then continued through the forest on foot. The deeper they went, the more obvious the changes became. Several old channels had dried completely while new streams had appeared between the trees. Animal tracks covered the muddy ground, but the direction of movement was inconsistent. Some creatures were heading toward higher ground, while others were moving toward the main river.

Camila studied the tracks.

"They're scattered now."

Subin crouched beside a large footprint.

"They're responding to different conditions."

Mateus looked around. "Can you tell what is happening?"

"Not yet."

Min-seok smiled. "At least you're honest."

Subin stood and continued walking.

By midday, the group reached a broad valley where the forest opened around the river. Hundreds of monsters had gathered along the slopes.

The scene was unlike the previous day's migration.

There was no single direction.

The creatures were separated into groups according to their strength and type. Large herbivores occupied the upper slopes, smaller creatures stayed near the trees, and several predators remained close to the river.

The strongest creatures had taken positions near the water.

"They're waiting," Yerin said.

Subin nodded.

"For what?"

"Something."

The answer came less than ten minutes later.

A deep rumble passed beneath their feet.

The ground shook lightly.

The monsters reacted immediately.

Every creature near the river turned toward the same direction.

Then the river rose.

Not gradually.

A wall of water surged around the bend, carrying trees, rocks, and pieces of broken earth downstream.

The team moved back instinctively.

Mateus looked at the valley.

"That's not a normal flood."

"No," Subin said.

The wave struck the opposite bank and spread across the lower forest.

The monsters began moving uphill.

This time, however, they weren't panicking.

They were following established routes.

The larger creatures moved first, creating paths through the vegetation, while the smaller creatures followed behind them.

Subin watched carefully.

"They've done this before."

Camila looked at him.

"You mean they've experienced the flooding already?"

"Not necessarily these exact creatures. But their behavior is learned."

The group followed the migration toward higher ground.

Then they heard a roar from the opposite side of the valley.

A massive creature emerged from the forest.

It was larger than the River Tyrant from the previous day, with six powerful legs and a thick body covered in dark armor.

The creature's level appeared on their scanners.

Level 134 — A+

It charged toward the migrating monsters.

Min-seok immediately raised his axe.

"That one doesn't look interested in running."

Subin watched the creature.

It wasn't attacking randomly.

It was driving the other monsters away from the upper valley.

"That's not an attack."

Min-seok looked at him.

"What?"

"It's controlling the movement."

The creature roared again and charged toward a group of horned beasts.

They scattered toward the western slope.

The A+ monster followed them, forcing them away from the river.

Jae-hyun understood.

"It's herding them."

Subin nodded.

The realization was short-lived.

A second roar came from the forest.

Then another.

Three more high-level creatures emerged.

All of them were moving toward the same valley.

The situation changed immediately.

The monsters were no longer simply responding to the flood.

The strongest creatures were competing for control over the safer territory.

Mateus drew his weapon.

"That's going to become a battle."

Subin nodded.

"Yes."

The first A+ creature charged another.

The collision shook the ground.

Their fight was enormous. Neither appeared interested in the humans, but the valley was too small for such creatures to fight without affecting everything around them.

Trees snapped under their weight.

Several monsters fled.

The two creatures collided again, and a wave of displaced earth rolled toward the lower slopes.

Subin looked at the migrating creatures.

"If they keep fighting here, they'll crush half the valley."

Min-seok smiled grimly.

"So we stop them?"

"Yes."

The team moved.

Yerin and Camila took the left side, guiding smaller monsters away from the battlefield. Ethan and Liu Wei moved toward the right flank, preventing the creatures from being trapped against the cliffs. Jae-hyun and Mateus concentrated on clearing the path ahead.

Subin approached the two A+ monsters.

The first noticed him.

It turned immediately.

Its massive foreleg came down.

Subin jumped aside, the impact sending soil into the air. He landed on the creature's shoulder, ran along the armored surface, and struck between two plates.

The monster roared and twisted violently.

Subin jumped clear.

His first strike had barely penetrated.

The creature was stronger than the River Tyrant, and its armor was significantly denser.

Subin didn't attack again immediately.

Instead, he watched.

The monster was protecting a narrow stretch of higher ground.

Every time another creature approached, it drove it away.

It wasn't trying to kill the others.

It was defending the territory.

Subin understood.

He changed his approach.

Rather than attacking the creature directly, he moved toward the second A+ monster.

The second creature immediately turned toward him.

Subin deliberately entered its attack range.

It charged.

At the final moment, he stepped aside.

The monster's body slammed into the first creature.

The two giants collided.

The first roared and pushed the second backward.

Subin moved between them.

His sword flashed.

The strike landed against the ground between the two creatures, splitting the soil and forcing both to separate.

They turned toward him.

For several seconds, the entire valley seemed to freeze.

Subin stood alone between them.

Then both monsters attacked.

The first came from the left.

The second from the right.

Subin didn't attempt to overpower either.

He moved through the narrow space between their attacks, using their enormous bodies against each other. One creature's strike forced the other to change direction, while every movement created another opening.

His sword moved repeatedly, not to kill but to redirect.

A cut against one leg.

A strike against the armored shoulder.

A shallow line across the side.

The creatures became increasingly frustrated.

Then the first monster made a mistake.

It committed too heavily to a forward attack.

Subin stepped inside its reach.

Simple Edge moved once.

The sword pierced through the gap between its armor plates.

The creature stumbled.

Before it could recover, Subin struck the same location again.

The monster collapsed onto its side.

The second creature roared and charged.

Subin turned toward it.

This time, he didn't move away.

The creature's head came directly toward him.

At the last moment, Subin stepped forward and cut upward.

The strike opened a deep wound beneath its jaw.

The creature staggered.

Subin followed with a second cut across its front leg.

The monster collapsed.

The battlefield became silent.

Subin stood between the two fallen A+ creatures, breathing steadily.

The remaining monsters stopped moving.

Then something unexpected happened.

The largest herbivores began descending from the higher ground.

They passed the fallen predators without attacking them.

Instead, they moved toward the newly cleared valley.

Yerin approached Subin.

"You didn't kill them."

"They weren't attacking humans."

Min-seok looked at the two wounded creatures.

"They'll survive."

"Probably."

Jae-hyun walked over.

"You deliberately fought them without killing them."

Subin nodded.

"They were fighting over territory. Removing both would create another problem."

Mateus understood.

"If we kill every powerful creature, weaker monsters will occupy the area."

"And the ecosystem changes again," Ara said.

Subin nodded.

The team watched as the monsters gradually settled into the valley.

The strongest creatures had been defeated, but the others didn't flee.

Instead, they spread throughout the newly available territory.

The immediate conflict was over.

But the mission had revealed something more important.

The dungeon was no longer the only source of change.

The creatures themselves were beginning to organize their behavior around the changing environment.

That evening, the team established camp on higher ground.

The atmosphere was noticeably more relaxed.

Min-seok sat beside the fire, cleaning his axe.

"You know, you're getting annoyingly good at fighting without killing everything."

Subin looked at him.

"Is that a compliment?"

"No."

Yerin laughed.

Jae-hyun shook his head.

"You were disappointed when the monsters ignored us. Now you're complaining because Subin didn't kill them."

Min-seok looked offended.

"I'm consistent."

"No, you're not."

The argument continued for several minutes until even Liu Wei joined in.

Subin sat slightly apart from them, listening.

He had become accustomed to being surrounded by people who challenged him in different ways.

Min-seok challenged him through strength.

Jae-hyun through tactical thinking.

Liu Wei through swordsmanship.

Yerin through understanding him better than most people did.

Even Ara and the younger Awakeners he had trained had begun developing their own identities rather than simply following stronger people.

That mattered to him.

Strength had never been difficult for him to pursue.

Finding people who could walk beside him was much harder.

Later, Yerin joined him near the edge of the camp.

"You were smiling."

"When?"

"Earlier."

Subin looked toward the others.

"They're getting stronger."

"That's why?"

"Yes."

Yerin smiled.

"You really are a teacher now."

"I don't know about that."

"You are."

She looked at him.

"And you're enjoying it."

Subin considered denying it, then decided against it.

"Maybe."

Yerin leaned against the tree beside him.

"You've changed."

"I know."

"Do you miss the way things were?"

Subin looked across the valley.

"No."

The answer came naturally.

"There was a time when becoming stronger was the only thing I thought about. Now there are people I don't want to leave behind."

Yerin smiled.

"That's a good thing."

"Probably."

She looked at him.

"Definitely."

The next morning, the team received a message from the Association.

The situation had changed again.

Satellite monitoring showed that the South American dungeon had expanded toward the river by nearly four kilometers overnight.

More importantly, several new monster territories had appeared along the water system.

Director Kang's message was brief.

The river is becoming a permanent migration route.

A second message followed.

International authorities are requesting a permanent joint response team.

Subin read both messages.

This was no longer a temporary dungeon expedition.

A new kind of battlefield was forming.

Not between humans and monsters, but between human settlements and an environment that was changing faster than existing systems could adapt.

Subin looked toward the valley.

The monsters were already moving again.

This time, they weren't fleeing.

They were establishing territories.

He closed the message.

"We'll stay."

Yerin looked at him.

"How long?"

"Until we know where they're going."

The team began preparing for another journey upstream.

Behind them, the defeated A+ creatures were slowly recovering, while the other monsters settled into the valley they had fought over.

The river continued toward the distant dungeon.

And for the first time, humanity had encountered something that could not be solved simply by clearing a dungeon.

The world was developing new territories.

Humanity would have to learn how to claim its place within them.
