Hidden Inheritance Ground

A light rain pattered down.

In the distance, Hokage Rock was shrouded in mist.

Chiye Jun ran to the valley at the outermost edge of Konoha, where a river and waterfall came into view.

On either bank stood two enormous ninja statues.

Hashirama Senju and Madara Uchiha formed the "Reconciliation Seal," symbolizing the complete end of Indra and Asura's fated battle.

But...

Thinking of the battle Sasuke and Naruto would fight here in the future, Chiye Jun could not help but sigh...

Then, he summoned the check-in panel.

[Ding! Congratulations, Host, on completing the check-in mission. Reward: antidote ninjutsu—Ten Thousand Poisons Yellow Springs.]

Ten Thousand Poisons Yellow Springs?

Chiye Jun remembered that, in the Naruto world, detoxification could be done by using the "Delicate Illness Extraction Technique" to identify the source of the poison.

Then, one could cut open the affected area with a "Chakra Scalpel" and draw out the toxin.

Finally, the antidote would be prepared.

He had wondered back then why there was no ninjutsu that could directly detoxify someone.

And now, it had really appeared!

What excited him even more was that this skill was actually an S-rank forbidden technique...

But why was it called Yellow Springs?

Then he discovered that checking in at the Valley of the End was merely one link in a mission chain!

Two new missions would appear one after another.

[Ten Thousand Poisons Yellow Springs is an S-rank forbidden technique capable of neutralizing all poisons in this world.]

All poisons?

That was freaking awesome!

Chiye Jun thought of Black Salamander's poison sac, Torune Aburame's poison insects, that snake guy's curse mark toxins, and the poisons concocted by Sasori of the Red Sand...

All of them could be cured!

Then, a thought suddenly struck him.

"Why is it a forbidden technique? Could it harm the body...?"

[Frequent use of Ten Thousand Poisons Yellow Springs will cause poison backlash to the caster, damaging the nervous system and resulting in dizziness, memory loss, or even dementia. It is therefore classified as a forbidden technique.]

"Then what the hell is the point of detoxifying anyone..."

[However, Host, rest assured. Under the Clear-Sound Bodhi Constitution, poison backlash will be blocked, preventing neural damage.]

Holy shit!

The Clear-Sound Bodhi Constitution could not only immunize him against genjutsu, but also block poison backlash?

Did that mean he was immune to all poisons?

[Not exactly. They are two different concepts...]

All right...

It seemed true poison immunity required another constitution.

Just as he was about to leave, the system issued another mission.

[Ding! Check-in mission issued. Please follow the instructions and arrive at an unknown location to check in.]

An unknown location?

Where could that be...

At that moment, the drizzle abruptly stopped, and sunlight flooded the land.

Chiye Jun sprinted along the riverbank.

A rainbow arched out from the river valley, its colors dazzlingly intertwined.

Chiye Jun had no time to admire the scenery. Following the system's instructions, he reached the river and dove in.

Only then did he discover a cave opening in the valley wall.

It was exactly the entrance indicated by the system!

Filled with curiosity, he swam inside.

After diving several meters, the narrow passage suddenly opened up at its end.

He surfaced, took several deep breaths, activated Super Sensory Technique, and used its night vision to look ahead.

Before him was a massive cave, as large as a training ground!

After climbing ashore, something suddenly landed on his shoulder...

Chiye Jun focused his eyes and looked.

Holy shit!

It was a pale arm bone!

That scared the hell out of him...

What kind of place was this?

Chiye Jun flung the bone away. It landed in a huge pit ahead, making a crisp cracking sound as it shattered.

He cautiously stepped forward and looked inside.

What the hell!

A burial pit...

Bones were piled up inside like mountains. Judging from their shapes, there were livestock and humans alike.

"Konoha hasn't heard of any missing people or livestock. Where did these bones come from...?"

Deep within the cave, Chiye Jun found that the ground was covered by a layer of fine sand.

He bent down and brushed it aside, only to reveal a dark, gleaming stone slab beneath it!

There was even a handle set into the groove on the slab!

"A hidden door!"

Curiosity stirred within Chiye Jun. He grabbed the handle and pulled with all his strength.

With a click!

The stone slab was lifted open.

A powerful stench of mold rushed into his nostrils, and he hurriedly covered his mouth and nose.

He passed through a dark passage covered in moss and arrived at the exit.

A dense forest appeared before him.

It was gloomy and eerie, utterly lifeless.

Chiye Jun continued forward until he approached a house built from piled-up white bones!

Around the house were jars and bottles filled with insects.

They were covered in dense spiderwebs...

Inside the house sat a young woman.

Her clear eyes shone like stars. Her long white hair draped over her shoulders, giving her an air of softness and nobility.

Her thin lips were as tender and alluring as rose petals.

What a breathtaking beauty!

But her skin was far too pale, like that of a corpse.

Even more frighteningly, the beauty was feeding an ugly toad with her own mouth...

"Come closer, little one."

Chiye Jun secretly summoned Blackie, then walked forward.

Only then did he smell the rotten corpse stench coming from the beauty's body...

"Hehe, what a cute black cat."

Chiye Jun was stunned!

She could actually see the invisible Blackie!

Who the hell was this woman?

"Little one, don't be afraid. This is Poison Nether Forest."

"Poison Nether Forest?" Chiye Jun froze. He had never heard of this place in the Naruto world.

"Poison Nether Forest is an inheritance ground like Ryuchi Cave, Mount Myoboku, and Shikkotsu Forest."

An inheritance ground!

Sage Mode!!

Then was the person before him a sage like the White Snake Sage, Great Toad Sage, and Slug Sage?

No wonder she could see Blackie.

The beauty seemed to understand his thoughts and smiled.

"That's right. I am the Spider Sage."

As soon as she finished speaking, she transformed into her true form!

A giant widow spider appeared, except its head was a terrifying skull with two little braids tied on top...

"Poison Nether Forest..."

Chiye Jun murmured.

Judging by the name, it should have something to do with bones, insects, and gu arts.

As he pondered this, the system popped up.

[Ding! Congratulations, Host, on completing the check-in mission and discovering a secret realm. Reward: unlock the passage to Poison Nether Forest.]

"A passage? Shouldn't you be rewarding me with some badass sage techniques?"

Fuck...

That was it?

Before his words had even faded!

The system popped up again.

"Uh... Today's mission is actually a mission chain! That's awesome!"

[Ding! Check-in mission issued. Use Ten Thousand Poisons Yellow Springs to detoxify someone within two days.]

"This one's easy. I'll go to Konoha Hospital!"

Just then, Sister Spider crawled over.

Two beams of white light suddenly shot out from the hollow eye sockets of her skull head.

Chiye Jun's mind went blank, and he passed out.

When he woke again, he was lying by the river.

Chiye Jun rubbed his eyes and recalled what had just happened.

"Unlock the passage? So where exactly is that passage?"

Suddenly!

He thought of Doraemon.

He immediately entered Universal Space with his mind.

Sure enough!

Not far from the library, a white arched gate had appeared, bearing the mark of a spider.

But the gate was tightly shut, and he could not enter for now.

"This should be the passage to Poison Nether Forest. I just wonder what sage techniques I'll be rewarded with in the future..."

Chiye Jun left the space.

Outside, the sun shone brilliantly.

When he had watched the anime before, he had noticed that Konoha Village seemed to enjoy spring all year round, with everyone wearing short sleeves every day...

Only after arriving did he learn that the Land of Fire was near this world's tropical region.

That was why even autumn carried no trace of chill.

The sunlight was pleasantly warm.

Ahead lay a sea of colorful flowers that soothed the heart and refreshed the mind.

"Huh, why do I smell so bad?"

Chiye Jun sniffed like a hound. The smell seemed to be coming from his own body.

"It must be the rotten stench I picked up in that forest."

Thinking so, he decided to wash himself in the river.

So he jumped into the river again and began washing.

Afterward, he tried to find the cave entrance leading to the secret realm, but it had already vanished.

On the other side of the river was a lush, dense bed of reeds.

Chiye Jun swam all the way to the shore.

Just as he was about to climb out, he accidentally caught sight of a shadow moving among the reeds across from him...

Who was that!

The King of Field Battles...
