Mysterious, but Naruto

With Louis's experimentation, he easily created his first ninja tool.

It was called an "experiment," but it was more like a natural and logical practice.

He had already mentally rehearsed the process countless times, memorizing the properties of various materials, the flow path of chakra, and the arrangement and combination of sealing techniques.

Therefore, when it came to actually doing it, the movements were surprisingly smooth, as if it were just transferring a pre-drawn blueprint from the mind into reality.

At first glance, this ninja tool looks similar to Audrey's bracelet, or you could say it's a plus version of that bracelet.

Its main body looks like an inconspicuous matte dagger, with a blade no more than the length of an adult's palm. The handle is wrapped with non-slip dark leather, and the overall design is low-key and understated.

However, once the user infuses chakra into it, the dagger comes to life, its blade flowing, extending, and being reforged like mercury.

Ultimately, it will transform into all sorts of weapon forms: scimitars, short swords, battle axes, longbows, chains, and even some strange weapons whose names are unknown.

More importantly, Louis incorporated the extraordinary essence of Sequence 9 "Criminal" into it, an action that gave the ninja tool almost unbelievable abilities.

As soon as the user grasps the weapon, their spirit instantly establishes a hidden connection with the spirit world, and then obtains the corresponding weapon's usage skills from that vast and chaotic spirit world.

This is not simply the transmission of muscle memory, but an almost instinctive infusion: the person wielding the knife will know how to swing it with the least effort, and the person drawing the bow will know how to aim most accurately.

Simply put, by transforming this dagger into a longbow, the user can temporarily become a master archer for a very short period of time with the help of the spirit world.

While it may not be as exaggerated as making users hit the bullseye instantly or achieve perfect accuracy from a hundred paces away, its hit rate is far superior to that of ordinary people who have only undergone regular training, at least within normal combat distances.

If it becomes a longsword, the wielder will automatically master a series of sword techniques such as parrying, thrusting, and deflecting force, as if these actions have been practiced thousands of times.

Furthermore, with prolonged use of the same weapon, even when not using the ninja tool, one will subconsciously utilize the acquired memories, but due to the lack of real-time adjustments from the spirit world, the effect will be much weaker.

However, nothing in this world is perfect.

Correspondingly, there is also a small but not negligible problem—during the use of this ninja tool, the user's spirit will be continuously eroded and affected by the chaotic aura of the spirit world.

At first, the changes may not be obvious; people simply become calmer than usual, and their emotional fluctuations are greatly reduced, with fear, anger, and excitement all fading away.

This is actually very beneficial in combat, as it allows one to remain undisturbed by excessive emotions and maintain the most rational judgment at all times.

However, if used for too long, this "calmness" will gradually change.

Users will gradually lose normal emotions, stop caring about the people around them, lose interest in things they once loved, and even gradually stop valuing life, whether it is their enemy's or their own.

By then, the line between killing and mercy will become blurred, and the scales of ethics and morality will begin to tip.

Once this stage is passed, the true, and most terrifying, side effects of this ninja tool will be revealed without reservation:

Users will become utter slaves to their lust, and the primal urges that have been suppressed by civilization and education for so long will burst forth like water bursting its banks.

To satisfy their own evil desires, they will commit crimes without any scruples, robbing, harming, betraying... all the acts that were once despicable to them will become justified.

Louis was not actually satisfied with this.

He even suspected that he had made a mistake in the production process, so he repeatedly reforged the ninja tool several times, adjusted the structure of the internal seal, changed the embedding method of the crystal, and tried different chakra guidance paths.

However, after several attempts, he finally realized with dismay that this side effect could not be avoided—no matter how he modified the external techniques, as long as the core ability remained unchanged, the aftereffects were as stubborn as a bone-deep infection.

After all, this is not a design flaw in the weapon itself, but rather stems from a fundamental premise: if the user wants to acquire various weapon usage skills through this ninja tool, they must establish a connection with the spirit world.

Those aftereffects are not curses attached to the equipment, but rather the "aura" inherent in the spirit world itself—that chaotic realm filled with countless broken consciousnesses and primal desires, while opening its information database to you, will also quietly leave its mark on your heart.

Louis ultimately did not destroy it, but named it "Master of Weapons" and carefully stored it deep in his vault.

However, he did not stop there. Instead, he created several more ninja tools, purely ninja tools.

Each piece embodies different ideas and attempts; some focus on functionality, some explore new material combinations, and some try to bypass the "dead knot" of the spiritual connection.

Louis implanted an ingenious seal into all of these ninja tools that were later manufactured.

What's sealed inside isn't some extraordinary crystal, but a specific, complete memory.

It was a piece of pure information about the techniques for using a certain weapon, refined and organized by Louis himself.

Once the user injects chakra into the ninja tool, the seal will automatically activate, and that memory will appear in the user's mind like a brand, allowing them to instantly master how to use the corresponding weapon.

These ninja tools have no side effects that alter the user's temperament, and are safe and reliable to use.

However, compared to the "Weapon Master's" ability to transform at will, they cannot change their form at will.

Each ninja tool can only be used as one type of weapon; a dagger is a dagger, and a spear is a spear. They cannot be switched freely in battle like the former.

It's not that it's impossible to make a ninja tool have multiple forms.

For example, Louis could further seal a large number of memory fragments within Audrey's bracelet and set corresponding conditions.

When the ninja tool transforms into a longbow, it activates archery memory; when it transforms into a short sword, it activates swordsmanship memory; and when it transforms into a chain, it activates binding techniques.

Theoretically, it is possible to achieve this if the sealing technique is complex enough.

However, compared to directly injecting the "criminal's" extraordinary crystals into the weapon, this method is much more troublesome.

After all, extraordinary items are essentially the same as extraordinary individuals; they only grant the user the right to use the corresponding abilities. The actual abilities and knowledge are not stored inside the extraordinary items.

In other words, an extraordinary item is just a hyperlink. You only need to paste the link corresponding to the actual ability onto the item to complete the creation.

However, if Louis's ninja tools are to achieve the corresponding abilities, then all the linked content really needs to be copied into them.

It's not that it's impossible, but it's quite obvious which of the two methods is simpler and which is more difficult.

As for the remaining extraordinary crystal of Sequence 8 "Fallen Angel", Louis, having learned from his previous experience, crafted it into a fan.

This fan is similar in style to a European court fan, with a gorgeous ivory handle at the bottom and a row of peacock feathers on the fan surface.

When you wave the fan, you can blow out a large cloud of black mist, and this black mist is no ordinary thing.

It not only combines the slowing mist of the previous attacker, but also the illusion technique of Dark Walk.

In this way, those shrouded in black mist will immediately lose their vision and be unable to see any light.

After being deprived of sight, the lack of interaction with the outside world can cause the victim to ignore the fact that their own thinking and body are becoming sluggish.

By the time they realized what was happening, they were already severely poisoned and it would be difficult for them to recover in a short time.

Besides the black mist, the fan can also fan out a ball of flame, which is a ghostly green color.

At first, Louis was puzzled by the sudden appearance of the fire ability.

After his analysis, he discovered that this actually originated from the power of Sequence 8 "Fallen Angel".

Sequence 8 "Fallen Angel" can not only release black mist, but also grant people the ability to release poisonous fire and curse those who "speak ill of others".

These forces all have in common that they make people slow down, only the manifestations differ.

Like the previous attacker, who only gained the ability to create black smoke from it.

So Louis simply incorporated ninjutsu into it: Fire Release: Flame Bullet.

It's not about regenerating a flame, but rather using the first part of this ninjutsu, which is to create chakra oil using chakra.

The poisonous fire combined with the chakra oil not only intensifies the flames but also increases their adhesion. Once it lands on an enemy, unless a layer of skin is peeled off, it's impossible to easily get rid of the flames.

Moreover, the chakra oil itself can act as a fuel, making the flames even harder to extinguish.

Similarly, this fan also has a side effect: once you hold it in your hand, you'll unconsciously feel like you're going to be sarcastic or offensive to others.

At first, it might just be a few sarcastic remarks, but the words will become increasingly vicious, and eventually, the urge to curse will even surpass the desire to fight.

In contrast, Louis thought that the insults were easier to deal with, so he simply left a seal on it, preventing the holder from speaking.

In this way, the holder will be filled with the desire to confide, but because of the seal he left behind, he cannot say anything.

The conflict between the two factors will make the holder increasingly anxious and irritable, and their emotions will become more agitated, but at least they will not stand still and curse without taking action.

Before storing it in the vault, Louis gave it a name that he thought was very fitting—Silent.

Just as Louis had satisfied his desire to act and was preparing to leave the Divine Tree space...

One of his clones spontaneously disintegrated, transmitting the information into his mind.

It turned out that the saint Flora Jacob, whom he had used as a practice subject, had already woken up.

Louis felt a little guilty about this, after all, he might have been a little too rough when helping the other party recover, to the point that the other party's soul was torn into tens of thousands of pieces.

Not to mention, during this process, Louis also used fragments of the other person's soul to conduct numerous experiments.

It took Louis three days just to piece those soul fragments back together, so even Louis was surprised that the other party could still wake up.

However, since the other person has regained consciousness, it proves that Louis's treatment was effective.

Fortunately, the treatment was effective, so we can't say that there was anything wrong with the previous procedures; we can only say that his treatment method was rather special.

When Louis arrived in front of Flora Jacob, the latter had already been awake for some time and had naturally seen the sky of this divine tree space.

Unlike Audrey or Earl Hall, Flora Jacob had at least risen to the rank of Saint and was quite familiar with the spirit world.

She even entered the spirit world multiple times by stealing the abilities of others.

Sometimes it's to escape, and sometimes it's to come here for divination and to obtain resources.

It was precisely because of her understanding of the spirit world that she knew the incredible nature of the area she was in.

In her memory, she had never heard of anyone having such a world in the spirit realm.

Oh no, there are some, but for the moment she could only think of the underworld and the legendary kingdom of gods.

Therefore, although she noticed some changes in herself, she didn't make any big moves. She just quietly observed the place, avoiding any behavior that might disturb anything.

Louis approached Flora Jacob, who was looking around aimlessly in the meadow.

"You're awake. How do you feel? Is there anything that hurts you?"

You're lucky. I found a fight going on in a back alley in the West End, but all I found on the ground was a rat whose identity had been stolen.

Furthermore, the rat's condition was extremely poor, and it was on the verge of going completely out of control.

Originally, I wasn't planning to intervene, since I didn't know why you were fighting.

Nobody knows what kind of person you really are. What if you're a heinous criminal who came to punish you, and I end up saving you instead? Wouldn't I then become an accomplice?

But seeing you shaking your head on the ground, as if you couldn't take it anymore, I can't even imagine how much harm a saint could cause to the citizens in a short time if he really lost control.

That's why I brought you here and treated you.

While theoretically speaking, as long as you don't have any problems, this is my first time performing this procedure, and the soul is an extremely complex entity. The specific outcome, and whether you are truly cured, will depend on your own experience.

Flora Jacob immediately expressed her gratitude to Louis for saving her life and restoring her to human form.

It wasn't that Flora Jacob herself was easy to talk to. When Louis appeared, she had already subconsciously used her ability. However, instead of directly stealing him, she first activated her spiritual vision to investigate Louis's background.

As soon as Flora Jacob opened her spiritual perspective, she was terrified by what she saw.

Normally, she can sense various colors and brightness of light on the target.

Different colors represent different attributes and properties, while the degree of brightness represents intensity.

In Flora Jacob's eyes, Louis was terrifyingly bright, and in just a moment, it made her eyes water, forcing her to close them.
