The Multiversal Travel System

It was already morning, and I was sitting in the kitchen, enjoying my breakfast.

Suddenly, an idea crossed my mind: there was something I hadn't tried in the system shop.

"System, can I buy anything from this world in the shop? Like bloodlines and Kekkei Genkai?"

[Host, the system can provide you with anything from this world that you desire.]

"Then, system, open the shop."

[Shop opened]

Advanced Random Box → 15,000 P.S

Epic Random Box → 25,000 P.S

Legendary Random Box → 50,000 P.S

"Random Box"… I have a suspicion of what it is, but I'd better ask the system to confirm it."

"System, can you explain the types of random boxes?"

[Of course, host. Detailed explanation below:]

Standard Random Box: Contains two rewards from this world, one of Normal category and one Special.

Advanced Random Box: Contains two rewards, one of Special category and one Rare.

Epic Random Box: Contains two rewards, one of Rare category and one Epic.

Legendary Random Box: Contains two rewards, one of Epic category and one Legendary.

"Interesting… very interesting."

"System, show me my current points."

[P.S = 25,000 P.S]

"I don't have many, but with the 50% discount in the shop, it's enough for a legendary box."

My mother would say I should save, but the thrill of gambling outweighs reason.

"System, use the discount and buy a legendary box."

[Confirmed. P.S = 0. Legendary Box acquired. Would you like to open it now?]

"Yes."

[Opening the box…]

Epic Reward: Sage Mode of the Six Paths Lv 1

Grants absolute control over natural chakra and the power of the Rikudō Sennin. Doubles all statistics and increases as the skill levels up.

Allows flight and the use of techniques without seals (blocked until max level).

Grants access to the True Spheres of the Path (blocked until max level).

Improves control of any other power you possess (blocked until level 5).

"This is insane… and it's only an epic category!"

Suddenly, I feel a strange chakra around me.

"I guess this is natural chakra. If I absorb it and mix it with mine, I should activate the Sage Mode of the Six Paths. But since I've never done it before, I'd better wait until I learn Natsumi's Shadow Clones… I don't want to risk messing up and ending up in trouble."

"Let's see what the legendary reward is.

Primordial Ascension of the True God (EX-Universal)

"Eh?"

[Description:] "You have been chosen to transcend all that exists. Your being will no longer be bound by the laws of reality, becoming an omnipotent entity."

Effects:

Infinite and Absolute Chakra.

Total Dominion over Time, Space, and Reality.

True Immortality and Indestructibility.

Unlimited Creation and Destruction.

My heart races. "This is too much… even for me."

Suddenly, unbearable pain pierces my body. My chakra goes out of control. My skin begins to crack as if I am disintegrating.

—"AGHHHHH!"

[SYSTEM ERROR: YOUR BODY CANNOT WITHSTAND THIS REWARD...][CANCELLING TRANSFER...]

My vision blurs. I feel my entire being being torn apart.

[ACTIVATING COMPENSATION AND HEALING...]

[CONGRATULATIONS: YOU HAVE OBTAINED THE FOLLOWING REWARDS:]

Jubi Chakra (Legendary)

God Tree Fruit (Legendary)

Suddenly, the pain disappears. Although my body is exhausted, I remain intact.

—"Haa… haa…"

I look at my hands and feel a completely new energy flowing inside me. The Jubi chakra… the God Tree Fruit…

—"I couldn't obtain the 'Primordial Ascension'… but this is still insane."

The system displays a final message:

[COMPENSATION COMPLETED: YOU NOW POSSESS A POWER SUPERIOR TO ANY ŌTSUTSUKI, YOU JUST NEED TO TRAIN TO FULLY GAIN IT.]

I clench my fists. "My goal remains intact."

Well, let's stop thinking like Sasuke.

Wait a moment… if Naruto in this world is female, could Sasuke be too?

Although, thinking better, I don't want as a partner someone capable of slicing my neck while I sleep just to gain more power and kill his brother. Sure, if in this world he remains male, it's out of the question.

Now I have a question, system. Since I already have the Jubi chakra, what will happen if I eat the God Tree Fruit?

[Upon obtaining the Jubi chakra in its complete form (Level 1), you will fuse the power of all Tailed Beasts inside you. However, consuming the God Tree Fruit will evolve you beyond any being in the shinobi world.]

[Your chakra will become unlimited, you will gain absolute resistance and instant regeneration, even if your body is destroyed. Your power will surpass that of Kaguya, and you will gain abilities such as:]

Biological Immortality.

Creation and manipulation of dimensions.

Absolute control of reality within your chakra.

[Additionally, by becoming a pure Ōtsutsuki, you will obtain the Byakugan and Rinne Sharingan, along with all of their less powerful variations.]

—"Less powerful variations? Can you explain which ones they are and their abilities, including those of the Rinne Sharingan, system?"

[Of course, host. The variations would be as follows:]

Sharingan – "Spinning Copy Eye"

The Sharingan is the most primitive version of the Rinne Sharingan. It is a powerful dōjutsu but limited compared to its evolutions.

Abilities:

Jutsu Copying: Can imitate ninjutsu, taijutsu, and genjutsu.

Enhanced Perception: Allows seeing movements in slow motion.

Movement Prediction: Anticipates attacks by reading the opponent's muscle tension.

Low-Level Genjutsu: Can hypnotize or confuse enemies.

Evolution: The Sharingan can evolve into the Mangekyō Sharingan if the user experiences significant emotional loss.

Eternal Mangekyō Sharingan

The Eternal Mangekyō Sharingan is extremely powerful, though it still has certain limits compared to the Rinnegan or Rinne Sharingan.

Each user develops unique abilities. However, since your Mangekyō Sharingan comes from the Rinne Sharingan, you will have access to ALL abilities of almost all known Mangekyō Sharingan.

Abilities:

Greater Duration and Lower Chakra Consumption.

Amaterasu: Unquenchable black flames.

Kagutsuchi: Control and manipulation of Amaterasu.

Tsukuyomi: Extremely realistic torture genjutsu.

Kamui: Teleportation and access to a personal dimension.

Kotoamatsukami: Absolute mental control without the victim realizing it.

Susanoo: Chakra avatar with armor and divine weapons.

Perfect Susanoo: Comparable to the power of Ōtsutsuki.

Unique Technique:

"Kurami no Shisen" - "Gaze of Darkness"

Completely erases the user's presence, making them invisible even to dōjutsu.

Totally nullifies sound, smell, and chakra, rendering you undetectable.

Lasts only 30 seconds, but during that time, even the Rinnegan cannot detect you.

Rinnegan – "Reincarnation Eye"

The Rinnegan is more powerful than the Mangekyō Sharingan but still does not reach the level of the Rinne Sharingan.

Abilities:

Six Paths of Pain:

Gravitational control

Chakra absorption

Summonings

Mechanical transformation

Soul extraction

Resurrection (at the cost of your vitality, though this does not affect you due to your immortality).

Control over all chakra natures.

Rinne Sharingan – "Reincarnation Spinning Eye"

The Rinne Sharingan is the supreme version of all previous dōjutsu.

Abilities:

Infinite Tsukuyomi: Ability to immerse the entire world in an eternal illusion.

Total Access to Space-Time: Can move between dimensions without restrictions.

Global Genjutsu: Allows control of masses of people without the need for visual contact.

Amplification of all techniques of the Sharingan, Mangekyō Sharingan, and Rinnegan.

—"God! I have all the dōjutsu of the ninja world except for the Tenseigan! But… I think I can get it by evolving the Byakugan with system points when I have them," I said almost shouting with excitement.

System, can you tell me the bonuses of the Jubi chakra?

[Of course, host. They are as follows:]

Infinite Chakra – The user gains virtually unlimited chakra reserves, capable of sustaining techniques at a divine level without exhaustion. (Unlocked)

Absolute Regeneration – Can regenerate any damage, even amputated limbs or fatal wounds, in seconds. Immunity to diseases and aging. (Locked until Level 2)

Divine Strength and Speed – The user's physical ability exponentially increases, surpassing any living being. Even without techniques, their punches can destroy mountains. (Locked until Level 9)

Connection with Nature – Allows the user to absorb and manipulate natural chakra without limits, accessing Sage Mode without preparation or restriction. (Locked until Level 5)

Control of Gudōdama (Truth Spheres) – Allows the creation and manipulation of these spheres with absolute destructive properties capable of disintegrating anything on a molecular level. (Locked until maximum level)

Total Chakra Manipulation – Can control, absorb, and redirect any type of chakra, even that of other people, Bijūs, or enemy techniques. (Locked until Level 3)

Functional Immortality – As long as the user possesses the Jubi Chakra, they cannot die from natural causes. Even if their body is destroyed, they can regenerate completely. (Locked until Level 4)

Access to Bijū Form – Can adopt any of the Bijūs' forms, including Perfect Tailed Beast Mode and Jubi Chakra Mode, gaining all their abilities. (Locked until maximum level)

Enhanced Rinne Sharingan – If the user possesses the Rinne Sharingan, their power increases, allowing them to cast Infinite Tsukuyomi without limitations and distort reality. (Locked until maximum level)

Creation of Life and Matter – Can use chakra to create living organisms or matter out of nothing, similar to Hagoromo Otsutsuki's ability. (Locked until maximum level)

Universal Destruction Energy – In its final form, the user can destroy entire continents or planets with a single attack. (Locked until maximum level)

Wait a moment... One of the bonuses says "final form," so I fear I will have to learn to control it to transform into the Jubi. But the bonuses of infinite chakra and regeneration will remain.

[Yes, you are correct, host.]

Damn… System, tell me what the control percentage is.

[10%]

Okay, I guess I can use one tail of power and that with each level I will gain an additional 10% control, allowing me to access an extra tail.

In addition to a power boost for each tail, right, system?

[That's right, host. For each tail, you will receive a x2 boost, and when you reach 100% control, you will obtain a chakra mode and a Bijū transformation.]

(Chakra Mode)

(Bijū Transformation)

Then let's eat the fruit. System, open the inventory.

[Inventory]

In the top left, there is a spherical fruit, a bright white color with a slight golden hue. Its surface is smooth and reflects light, giving it an almost ethereal appearance.

It then appears in my hand. If someone else saw it, they would think it's a ball of light.

Without thinking too much, I take a bite. Immediately, the fruit disappears and begins to fuse with me. Suddenly, a great pain shakes my body, and I can't help but scream.

I feel like my muscles are tearing apart and reforming, as if my bones are breaking and regenerating instantly.

The pain is unbearable. I'm about to pass out, but before I lose consciousness, I see someone breaking down the door and rushing into my apartment.

The last thing I distinguish is hair like the sun… and then, I fall into unconsciousness.

To be continued...
