A translucent, faintly glowing window appeared in front of me the moment I clicked.
A smaller panel unfolded inside it, words written neatly across the top.
Welcome to the Multiverse Shop
Below it was a simple arrow and a scrolling interface.
Items I recognized. Items I didn't. Items whose names alone carried weight.
I frowned slightly.
If I browsed everything randomly, I would surely miss something truly powerful.
So instead of relying on luck, I filtered.
I dragged the price range slider.
[0 → 150,000 points]
Then I moved to categories and clicked on Barrier, Skills, Items and magic option.
After taking a deep breath, I clicked Confirm.
The screen flickered.
Hundreds of options appeared instantly, overlapping and rearranging themselves.
Too many. Far too many.
But only a few truly caught my attention.
---
[1. Limitless (Infinity)
World: Jujutsu Kaisen
Description: The neutral form of Limitless. It creates infinite space between the user and any incoming attack. Nothing can ever truly reach the user, as all movement is slowed infinitely before contact.
Price: 150,000 points]
It is powerful but I shook my head.
It didn't increase physical strength.
And more importantly—it couldn't isolate space itself.
I needed something that could separate this room from the outside world completely.
---
[2. ROOM (Ope Ope no Mi)
World: One Piece
Description: Creates a spherical domain where the user controls space freely—swapping positions, severing objects, or teleporting anything inside instantly.
Price: 140,000 points]
Tempting.
But ROOM was an active domain.
It wasn't meant to be a permanent barrier.
And maintaining it constantly would drain me dry.
Rejected and i moved to next item.

[3. Kamui
World: Naruto Shippuden
Description: A Mangekyō Sharingan ability that transfers objects or parts of the body into a separate pocket dimension, effectively phasing through reality.
Price: 120,000 points]
I dismissed it immediately.
Kamui was an eye technique.
More importantly, I would never place a portal inside the Kamui dimension.
What if something powerful escaped and occupied it?
I would be sealing my own strongest cheat.
That would be shooting myself in the foot.

[4. Mana Zone: Black Cocoon
World: Black Clover
Description: A spatial mana barrier that severs inside space from the outside, erasing anything that touches its boundary.
Price: 90,000 points]
I hesitated… then ignored it.
I didn't know enough about Black Clover's power system and even with Devil Fruit vitality, my physical stats were still closer to a ninja's. That's why I need something which can also increase my defence.

[5. Multi-Layer Barrier / Universal Barrier
World: That Time I Got Reincarnated as a Slime
• Multi-Layer Barrier – 100,000 points
• Universal Barrier – 150,000 points]
My heartbeat quickens seeing this skills. After all this skill can be used to cover the whole body as a defence and can be used to create powerful barrier which can even stop teleportation. Universal Barrier was clearly stronger—and cheaper in the long run.
But I paused.
If I put everything into one ultimate defense and later faced a dangerous Transmigrator…
I would regret having no flexibility.
I thought for only a second.
Then I made my choice.
Multi-Layer Barrier — Purchased
The moment the purchase completed, a strange energy surged through my body.
I instinctively guided it with chakra—and succeeded.
I wrapped myself in the barrier but instantly frowned.
"…Damn it."
The consumption was absurd.
[Isn't it obvious? It's a powerful skill.]
"Then how does Rimuru use it like breathing?" I muttered, then stopped myself.
Right.
Rimuru absorbed Veldora.
A being far stronger than even the Ten-Tails.
I exhaled slowly.
At my current level, I could only maintain this barrier for five minutes—and only at its most basic output.
[Why not replenish chakra using surrounding energy? Or better—natural energy.]
I stared at the system with narrowed eyes.
This thing really was designed to squeeze every drop out of me.
Calming myself, I scrolled again—this time through items from alternate ninja worlds.
One caught my attention immediately.
[Natural Energy & Chakra Supply Device – NECS for short.
World: Naruto (Alternate World)
Description: A specialized device designed by Orochimaru that supplies chakra and natural energy for scientific Ninja tools.
Price: 4,500 points]
I bought it instantly.
The moment I connected it to the barrier, relief washed over me.
The drain stabilized.
Now the barrier covered the entire room—and could even withstand a Tailed Beast Bomb.
Iafter doing this I also used multiple layer barrier on myself. An extremely thin barrier cover me.
Now, even if someone stabbed my eye with a kunai—it wouldn't matter.
Satisfied, I relaxed.
Then—
Rustle.
I froze and turned my head towards the sound.
A small rabbit stood inside the room, blinking innocently.
"…What?"
Before I could react, a much larger rabbit burst through the portal, grabbed the smaller one by the scruff, and leapt back inside.
The blue portal rippled once… then stabilized.
I stared.
Slowly.
My face darkened.
"…Don't tell me," I muttered, "this portal needs protection from both side"
