Night Vision Perk Activated!

Whoosh.

Sarutobi Ryo began the technique, and chakra slowly woke up the barrier.

The many lines of magical symbols glowed one after another, and each layer of defense was broken through.

This was a display of strength, but also a battle of smarts.

As the oldest son, Sarutobi Ryo inherited Sarutobi Hiruzen's skills as a Ninjutsu Doctor. He was incredibly talented.

Being a Ninjutsu Doctor meant he was skilled in all of Konoha's ninjutsu, except for those passed down through families or secret techniques.

This meant he could find a solution to any problem.

Sarutobi Ryo was still young, and his strength was only at the Jonin level. Naturally, he wasn't as strong as his father, Sarutobi Hiruzen, yet.

But this also showed that Sarutobi Ryo had huge potential. He was likely to achieve great things in the future. Mastering all seven chakra types and reaching his father's level was only a matter of time.

Soon, footsteps echoed again, and Yamanaka Hui and Hakumo Hayama ran back.

"Young Master, the enemies are strong... They're definitely from the Blood Mist Village!"

Kirigakure, also known as the Blood Mist Village, was known for its extremely cruel and bloody methods.

This cruelty wasn't just for enemies, but for their own people, too.

Rumor had it that ninjas from Kirigakure had to kill their close friends from the Ninja Academy - those they slept and ate with - during the graduation exam. Only the survivors became official ninjas.

These harsh rules created the bloodthirsty and crazy Blood Mist Village.

In a one-on-one fight, a ninja from the Blood Mist Village was probably better than ninjas from the other Great Shinobi Villages.

"..."

Sarutobi Ryo didn't answer Yamanaka Hui.

He was focused on breaking the barrier trap.

As he concentrated, Sarutobi Ryo felt himself entering a strange state.

He saw...

Sarutobi Ryo's right eye pupil shrinking and growing.

The effect was amazing. The many lines of barrier symbols were now perfectly clear.

Even the most hidden symbols were easy to see without a magnifying glass.

"Amazing..."

Sarutobi Ryo felt the changes in his right eye. This Will of Fire System is more than it seems.

Whoosh, whoosh!

The sound of kunai being thrown filled the air as Yamanaka Hui and Hakumo Hayama began to fight back.

The sounds of battle echoed in the hallway.

"It's no use, there are too many enemies!"

With a shua sound, Hakumo Hayama drew his sword.

He swung the long sword, and invisible wind gathered on the blade before being released.

"Wind Release: Vacuum Sword!"

The invisible air currents vibrated as several crescent-shaped blades of wind flew down the hallway.

This was Hakumo Hayama's special move, turning chakra into wind release, moving it along the blade, and then sending it out.

Chichichichi!

The first Kirigakure ninja blocked a few times, barely stopping the first two wind blades.

But when the third wind blade hit, the blade in his hand snapped with a crack , and a deep wound appeared on his chest.

Thump.

The body fell to the ground.

The ninjas from the Blood Mist Village behind him didn't even look at him. They stepped over his body as they charged forward.

Their wildness and brutality were greater than that of any ninja from any other village.

Ninjas from other villages would usually avoid the bodies of their fallen comrades.

But these guys treated their comrades' bodies like trash, using them as stepping stones.

Chih!

A sharp whistling sound rang out.

The kunai thrown casually by the enemy made Yamanaka Hui and Hakumo Hayama jump.

Hiss, hiss, hiss!

Smoke hissed from the end of the kunai with a loud hiss.

"It's an exploding tag! Get away!"

Yamanaka Hui, with her sharp senses, shouted and ran first.

Hakumo Hayama barely dodged, but because the hallway was narrow, he was hit by the blast and covered in dirt.

Rumble!

The underground passage shook from the explosion. Years of neglect had weakened it, and it began to collapse.

Cracks appeared on the walls and ceiling.

Stones and dust fell like rain.

Soon, the light dimmed, and darkness quickly took over the light from the ventilation shaft.

"Damn it! These madmen, aren't they afraid of collapsing this place?!"

Yamanaka Hui coughed a few times, complaining.

In the darkness, they couldn't see each other.

Sarutobi Ryo's progress in breaking the barrier wasn't affected at all.

At that moment, even Ruri, who had been quiet, curiously looked up at Sarutobi Ryo in the darkness.

Sarutobi Ryo wasn't just pretending. He had discovered some strange changes in his right eye.

[Fallen leaves return to their roots... the true Will of Fire!]

A message suddenly appeared on his right retina.

In the pitch-black underground, this line of text was very noticeable.

[Will of Fire System... loading new function!]

[Loading successful!]

[Night Vision module... activated!]

The darkness before his eyes suddenly disappeared.

In his right eye's vision, everything suddenly became incredibly clear, as if it were daytime.

"Interesting."

Sarutobi Ryo felt that this Will of Fire System, while called a system, seemed more like... a very advanced piece of technology.

"Then..."

Buzz!

All the symbols on the stone coffin flickered slightly, and the black spells disappeared. The stone coffin's barrier trap was gone.

While Yamanaka Hui was still sensing, she saw that the Young Master had already left the stone coffin, turned around, and walked outside.

In the pitch-black, the Young Master walked as if it were daytime, directly leaving the tomb chamber and heading outside.

"Young Master?"

Not only this tomb chamber, but also the hallway outside, was plunged into darkness.

The ninjas from the Blood Mist Village in the darkness didn't know an attack was coming.

Just as they were about to light the torches they carried, a dark figure silently stood before them.

He glanced at them.

The night vision ability of his right eye clearly saw the number of enemies.

Different objects and creatures gave off different amounts of heat, like a thermal camera. The shaking little mouse in the corner, for example, glowed in Sarutobi Ryo's vision with rainbow-colored heat patterns.

"1, 2, 3..."

In the narrow underground passage, Sarutobi Ryo's voice sounded.

"?!"

The Kirigakure ninjas who were reaching for their torches felt a chill. Before they could react, Sarutobi Ryo's right fist had already exploded like an angry dragon.

With a loud bang, the Blood Mist ninja at the front was sent flying.

But the sight of a fist blasting through flesh didn't happen.

As expected of Blood Mist ninjas... Their skills are much better than those from small villages like Soragakure...

After a quick thought, Sarutobi Ryo stepped forward, this time... without holding back.

With a full-force attack, Sarutobi Ryo's right arm cracked and popped.

His muscles suddenly grew and tightened to the extreme.

The attack wasn't aimed at the chest or other areas, but... directly at the side of the head!

Like a large iron hammer, a haymaker slammed into the side of the next person's head.

The power of this punch was so strong that it would shatter a 1-meter square rock.

And a rock with a 1-meter diameter falling from a height of about 6-10 meters could kill an average Chunin.

So, with a bang,

The enemy's face shook, his eyes rolled, and blood flowed from his face. He looked like he had been shot in the head, and he flew sideways.

"!!"

However, the death of their comrade only made the remaining Blood Mist ninjas even more brutal.

They had already used the chaos to light their torches, putting them into the cracks in the wall, and the firelight instantly lit up the entire hallway.

Then, they all gripped their blades tightly.

Sarutobi Ryo retreated calmly, while making hand signs with both hands.

"Water Release: Water Disruption!"

The most basic Water Release, the C-rank Water Disruption, had no attack power.

It was a basic technique that every Water Release ninja had to practice.

Normally, this technique was only for practice and training, or to put out fires, or to trigger certain devices as a helper.

However, this seemingly harmless technique directly put out the torches on the wall.

As the passage fell into darkness again, the underground once again became Sarutobi Ryo's home ground...
