Isekai Adventure in the Dimensional Cube

But just as this thought arose, when the magical array of the super magic [Wishing Upon a Star] was about to unfold before Reiger, he immediately received feedback from the magic.

This feedback told Reiger that even the seemingly omnipotent wish magic [Wishing Upon a Star] could not summon Beluti’s soul back from the dimensional rift.

Although this was an extremely unbelievable situation that left Reiger quite surprised, upon reconsidering, it actually wasn’t surprising at all.

[Wishing Upon a Star] also has its limits; not every wish can be fulfilled.

In the game "YGGDRASIL", the super magic [Wishing Upon a Star] is introduced as requiring, depending on the difficulty of the wish, up to the equivalent of level 5 experience points to realize a wish.

In other words, if the cost of the wish exceeds the level 5 experience points, then that wish cannot be realized.

The cost required to call back Beluti’s soul exceeds this limit.

It could be because the barriers between planes are so strong that even the Abyss requires a huge cost to penetrate, or because Beluti sacrificed not only her body but also her soul to close the Abyss Gate, leading to some deficit in the soul, or perhaps it’s the unique mechanics of this main world interfering in some way...

Various possible factors result in the difficulty of calling back Beluti’s soul exceeding the effects of [Wishing Upon a Star].

Thus, Reiger had to accept this reality and return to Melo and Naisa.

Otherwise, he would have tried to resurrect Beluti long ago, so why would he return empty-handed?

"How could this happen..."

Upon learning this reality, Melo and Naisa found it hard to accept.

They still refused to believe that the girl, as pure and sacred as an angel, like a white lotus, wouldn’t come back.

"Is there really no way?"

Melo’s lips were about to tighten.

To this, Reiger offered an explanation.

"I don’t have one." Reiger still calmly said: "But my lack doesn’t mean others don’t have one."

This was also why Reiger could remain calm.

At this moment, what Reiger thought of was not someone else, but that in his knowledge, the person with the highest achievement in magic and mystical arts — Morgan Le Fay.

She is a rare witch, a Paradise Fairy from the Inner Sea of the Star, a former savior who achieved many miracles solely by her talents.

She was able to recreate the Light Tower, Star Anchor, and Storm Spear that fixed the planet’s surface in the form of magic, establishing the power of the Holy Spear as a grand magic, allowing one to release a blow of the Holy Spear just by mastering this magic.

She also created a grand magic that could send anything back in time, achieving the miracle of time and space travel by personal power alone.

"Mirror", "Tower", "Court", "Coffin"... Morgan developed more than one grand magic, even spending two thousand years to develop the "Pile" that could bypass his skill immunity to work on Reiger.

And Reiger also knew that the witch had indeed deciphered Chaldea’s Heroic Spirit summoning system and spirit particle transfer system in an extremely short time, altering history to some extent.

The reason the Fairy Country Britain’s Lostbelt is currently known by Reiger to be as it is, like in the original works, is mainly due to this point.

If it weren’t for this, the Fairy Country Britain’s Lostbelt might have already become desolate, Morgan would have long perished and wouldn’t have turned into what it is now.

"If it’s her, there should be a way to do something."

This is not Reiger blindly pursuing a hope that should not exist.

If Morgan completely unlocked the secrets of the Heroic Spirit summoning system and could perform spirit particle transfer, then bringing Beluti’s soul back from the dimensional rift is entirely possible.

What is called Heroic Spirit summoning, in fact, is a ceremony to summon heroes originally existing on the "Heroic Spirit’s Throne" to the real world, allowing them to incarnate and resurrect.

And the "Heroic Spirit’s Throne" is located outside the world, a place free from time constraints, and spirit particle transfer allows adapted individuals to travel through history to singularities. If Morgan can completely analyze both, and make certain adjustments, then even if unable to directly summon Beluti’s soul back, it should allow Reiger to enter the dimensional rift to find Beluti’s soul.

At least, Reiger can have Morgan use "Water Mirror" to send himself back in time, to the point when Beluti’s soul hadn’t fallen into the dimensional rift yet.

And so, Reiger would have a chance to rescue Beluti.

That is to say...

"To revive Beluti, I must find her."

Reiger directed his gaze at Melo and Naisa.

"Before that, I will send you back to the Source."

...

The teleportation magic array for returning to the Source is in a mountain cave near the Nanierga Giant Wall.

Reiger had been there for reconnaissance during the days of repelling Abyss creatures.

Since the Abyss Gate was already closed and Reiger’s transfer abilities could be used again, he activated the [Portal], sending Melo and Naisa directly there, temporarily entrusting the Holy Sword Marfa to them to take back.

He will soon leave this world, so he cannot let the Source, having already lost a Holy Sword, lose another one, to prevent any issues with sealing the Abyss.

After doing all this, Reiger issued commands to the Dimensional Cube to initiate return.

"Accept command, this Dimensional Travel will soon end, beginning inspection."

"Detected user possesses world-specific power, can dissolve and return with the body."

"Detected user holds world-specific items, which can be brought back consuming energy."

"Unique item list has been listed; please choose accordingly."

"1: Library·Zambia (100)"

"2:..."

In his mind, a series of item lists began appearing continuously.

Apart from the Library·Zambia, the rest were mostly gifts received from various forces and races of the Source.

Though these gifts were precious, Reiger didn’t plan to take them.

Firstly, their quantity was enormous, hauling them all would undeniably require spending a lot of Dimension Energy.

Secondly, they weren’t precious enough for Reiger to need to take them with him.

Therefore, Reiger only prepared to take a few items worth taking, including the Library·Zambia, with the rest packed to be sent back to the Source, entrusted to Melo and Naisa.

"Speaking of... Just the Library·Zambia alone costs 100 units of Dimension Energy?"

This is definitely the most Dimension Energy Reiger has spent so far on assimilating items, and who knows how many valuable books are in there, leading the Dimensional Cube to list such an outrageous price.

Reiger glanced at his remaining Dimension Energy.

"Dimension Energy: 548"

Before the Dimensional Travel to the Jujutsu World, Reiger had 232 units of Dimension Energy remaining.

After staying in the Jujutsu World for 300 days without assimilating any items to take away, Reiger accumulated 300 units of Dimension Energy.

While in the Source World, Reiger stayed for about half a month.

All in all, he accumulated 548 units of Dimension Energy.

With so much Dimension Energy, Reiger wasn’t hesitant; he directly spent more than 100 units of Dimension Energy to choose several items worth taking, including the Library·Zambia, with the rest sent back to the Source.

"Selection complete, commencing execution."

"Item assimilation successful."

"Dimensional Travel ended, beginning return."
