I'm doing Jujutsu Kaisen in the ninja world.

It was as if it wasn't a person's shadow at all, but a symbiotic alien hidden inside.

As time went on, the three became more and more efficient in their killings, and more and more skilled in using their new abilities.

Moreover, they all retain their original human thinking and some of the instincts of cursed spirits.

Even during the fighting, this instinct is being amplified little by little.

Finally, all the monsters were killed.

The red in the eyes of survivors #1 and #2 faded slightly, and they knew they had passed the test.

However, before they could feel relieved, a black shadow quietly approached, then suddenly pounced and bit off the head of Survivor Number 1!

"What are you doing? Are you crazy?"

Survivor #2 stared incredulously at Survivor #3, who was laughing maniacally, before disappearing into the shadows without hesitation.

But this new ability couldn't save his life this time.

Since the ghost of Survivor 3 is itself a type of shadow, it can naturally enter it.

"No! Please let me go, ah!"

When screams and chewing sounds came from the shadows at the same time, the fate of Survivor No. 2 was sealed.

"Kill! Kill! Kill!"

At this moment, Survivor Number 3 was filled with thoughts of killing, completely controlled by instinct.

However, there were no other living beings in the entire space except for himself, and it was unclear how it had been treated. No one inside could get out, and even the second survivor from before couldn't escape using the power of the shadows.

Then Survivor #3 began to unleash a violent outburst...

The final outcome was that the ghost bit off the head of survivor number 3, which brought the matter to an end.

Since there's no one else to kill, I'll kill myself!

That's a terrible idea.

After the experiment was completed, the goat monster, having received the order, opened the special space and began cleaning up the severed limbs inside.

Because another batch of experimental subjects will be coming in here soon.

In fact, no one knew what the owner of this place wanted to do. All that was known was that from the beginning of the experiment, the initial mortality rate was extremely high.

But with repeated experiments, it is now possible to mass-produce those stupid monsters with low intelligence with 100% accuracy.

Furthermore, the number of humans gaining new powers is increasing, and stability is also improving.

This is undoubtedly a terrible thing.

. . . . . . . .

Outside, the killings continued.

After unleashing their full potential, Shinji and Hidan completely entered Musou-style mowing down of enemies.

It's a mode that completely abandons defense and only pursues maximum efficiency in killing.

It's not a big deal that Hidan always does this.

However, when Shinji goes all out, his destructive power is astonishing.

Without the blood limit, the Crimson Blood Manipulation Technique is like a meat grinder. No matter how far or near, anyone who enters Shinji's field of vision will be killed instantly!

A dozen bloody arms were attached to his back, each arm gripping a bloody blade, slicing the surrounding cursed spirits into pieces!

Countless bullets sprayed blood as if they were free!

At this moment, in Sasuke and Tamamo's eyes, he was a complete monster.

The first wave of hundreds of cursed spirits that jumped out were all wiped out.

To cover the rear?

There's absolutely no need for that.

It's more like watching a play.

Sasuke couldn't help but wonder when he would be able to become as strong as his older brother Shinji.

They pushed their way through like that.

Shinji was completely immersed in the thrill of mowing down enemies, especially the satisfaction of watching his 'savings' keep increasing, a happiness he couldn't share with anyone else.

If he could, he really wanted to keep grinding until he reached 20 Cursed Soul Points.

"The entrance is this way."

At this moment, Ah Fei suddenly shouted.

When everyone went over to take a look, they discovered that the mountain had actually been hollowed out, revealing a hidden world inside.

Are we just going to barge in like this?

Tamamo Hotaru swallowed hard, wondering how someone as small as her could possibly get involved in something like this.

The first wave of attacks already had so many monsters; now, entering the monsters' lair—even a fool could tell how dangerous that would be.

"Then you wait for us outside."

Shinji didn't care what she thought; after saying that, he went straight inside.

Even if the Sage of Six Paths came today, he wouldn't be able to stop him from clearing this dungeon!

Hidan, Sasuke, and Tobi, who was still saying he was scared, all went inside.

Yuzao Hotaru was completely flustered while holding Jiaoyue.

Especially after she began to feel that it was even more terrifying for her to be left outside alone, she shuddered and quickly chased after him.

"Wait for me..."

Waiting is of course impossible; Tamamo Hotaru doesn't have that kind of influence.

Fortunately, Shinji and the others hadn't gone too far, otherwise they would have really left her there.

[Chapter 304: Survival]

When the goat monster learned that the first batch of cursed spirits he sent had all been killed, he was stunned on the spot!

Then my heart started pounding!

If his owner finds out, he's doomed.

So he immediately put down his work and hurriedly left with a large group of modified spirits.

He had to deal with the intruder as quickly as possible, without delaying the experiment's progress, and even more importantly, without letting his master know about his dereliction of duty.

But is it really possible to do that?

. . . . . . .

"Such a big mountain, could it just be those shrimp soldiers and crab generals from before?"

Shinji walked in but didn't see any cursed spirits, and he was starting to wonder.

Then they saw a goat monster leading at least several hundred humanoid monsters surrounding them, and they were immediately overjoyed!

Good thing you came!

While the goat monster was surprised by the number of intruders, it didn't pay much attention to them.

"Kill them!"

Hundreds of humanoid monsters immediately charged forward in a massive wave.

Shinji raised the guillotine sword briefly, then lowered it again.

The blood flowing rapidly around his body showed a slight tendency to coagulate, but it quickly returned to its original state.

The main reason was that the opponent's formation and the environment here were very favorable to him.

If you don't yell it out, you'll definitely regret it!

He immediately concentrated a large amount of magical power in his throat, then activated the incantation, shouting, "Die!"

The word "death," imbued with terrifying curse power, began to echo.

Then hundreds of humanoid monsters suddenly stopped, then fell to the ground in unison, and were silent ever since!

Such a terrifying scene left Tamamo Hotaru with an expression of disbelief.

The power of a single word was enough to instantly kill so many monsters?!

Is this really something a human being can do?

What kind of ninjutsu is this?

Not only her, but everyone else was also taken aback.

At first, it was still within the realm of barely understandable, but what is it now?

"This guy is getting stronger and stronger..."

Ah Fei felt conflicted and didn't know what to do. His initial goal kept changing.

Shinji was prepared to die, but when he realized that the backlash was not as strong as he had imagined, his expression immediately changed!

Despite the deaths of so many monsters, his curse points didn't increase at all.

This is how the same thing?

Could it be that these monsters aren't cursed spirits at all?

Seemingly realizing something, Shinji frowned and immediately fixed his gaze on the goat-headed monster that was trying to sneak away.

Bang!

With one foot, the goat-headed monster was stomped to the ground, and the decapitation blade was pressed against his neck.

"What exactly are you? Humans, cursed spirits, or something else?"

"Don't kill me! Don't kill me! I'm a human being! I'm a human being!"

The goat-headed monster immediately begged for mercy and said something utterly absurd.
