After the full level, my soft rice system is long overdue

And Renata in front of him has been quietly listening to Ciel's explanation.

During the days when the legendary necromancer trained her into a sacrilegious weapon, he taught Renata a lot of knowledge about wizards.

In addition to what Renata left behind after his death, the last large library in the entire world that records arcane knowledge...

All these years, the only thing that Renata, who was sealed away and in this cage, could do was to read the ancient books left in the great library.

After 200 years of reading and accumulation..

Although Renata is not a wizard in the traditional sense, and she who is in charge of the authority of God has been able to do almost everything without the help of magic——

However, when it comes to the understanding of arcane and magic——

Carrying this world, Renata, the last inheritance of the once brilliant wizard civilization, is actually not inferior to ordinary legendary wizards.

Because of this, even though Shire's explanation is not very easy to understand, and has a strong jumping, if it is replaced by ordinary people, I am afraid that it will be no different from listening to heaven after a few words..

But Renata can also rely on her accumulated knowledge to easily follow Ciel's train of thought.

And this evening witch with black hair and golden pupils is indeed a qualified listener, and has been listening quietly.

It was not until Charles' explanation stopped that he obediently raised the small notebook.

"What you created.. This spell reproduces the principle of the internal reaction of the sun.."

"What's its name?"

"It has many names, such as "Controlled Nuclear Fusion", "Solar Furnace", "Fusion Reactor", "Planetary Engine".."

"However, if such a spell is to be applied to this world, a new sun will be lit in the endless night."

"Then I prefer to call it—"

Charles' voice paused slightly.

""Pseudo-Stellar""

..

"Frankly speaking, this forbidden curse is the most difficult existence among the dozens of forbidden curses I have created. Even the previous two forbidden curses for mythology are far from being comparable to it."

"And, until now, even if the surgical model itself has undergone countless improvements and verifications..."

"However, in actual operation, there is still a considerable degree of difficulty. I am afraid it will be difficult to succeed in one go..."

Ciel looked into Renata's eyes, and spoke word by word.

This was the first time he used such a cautious tone to describe a forbidden spell or magic.

Even if it was the previous "Sword of Damocles", or the nuclear explosion magic that wiped out the fallen sun god in one blow...

Although there was a lot of movement when it was released, in fact, Shire didn't really pay attention to it.

Those are all forbidden spells that have undergone countless field experiments and are too mature to mature.

In the process of releasing the forbidden spell, all the variables were completely understood by the caster Charr, and there was no possibility of any mistakes.

It's as if it was made from the branches of the world tree in ancient mythology. It can reverse cause and effect, and it will penetrate the target's heart just by throwing it.

The moment the forbidden spell was launched, the outcome of the second prince and the fallen sun god was already doomed.

but--

Compared with space-based kinetic energy weapons or nuclear explosions, the difficulty of controllable nuclear fusion exists in another world.

The principle of space-based kinetic energy weapons is not complicated. The difficulty lies in how to transport the launcher to low-earth orbit, the selection of arrows, and the precise calculation of the falling trajectory.

And from the "nuclear explosion" of the hydrogen bomb.

Although it has a similar principle to Shire's goal at the moment - the fusion reactor.

But as a purely destructive forbidden spell, you don't need to pay attention to it after triggering the chained collapse. You just need to wait for the internal magic power crystal to be exhausted and the magic power collapse chain to end.

And creation is always much more difficult than destruction.

To give an inappropriate example, it is the difference between killing an ancient dragon and taming an ancient dragon to make it as obedient as a pet cat, the difficulty is more than several orders of magnitude higher.

"It's not too difficult to simply let this technique run correctly and output light and heat for a few seconds...or tens of seconds."

"Let's not talk about this world where there are gods, extraordinary and magic—"

"Even in the world abandoned by the gods and cut off from the extraordinary, it can be done successfully for a short time."

"but.."

Charles' words were very quiet, but carried a heavy weight.

"What the civilization of this world really needs is not a few seconds or even tens of seconds of light..."

"It's—"

"Like a real star, burning steadily for decades, hundreds or even thousands of years—"

"Bring real hope and light to this world that has been silent in darkness for 200 years."

..

"The completion of this technique will be difficult...the process may also be very long."

"Take the triggering conditions of the fusion reaction as an example. The pressure inside the star is millions of times that of the real atmosphere, so the reaction can be carried out at a lower temperature—"

"However, we can't reproduce that high-pressure environment in reality, so we can only continue to increase the temperature—"

"The breath of the pure-blooded red dragon is already the hottest existence that most people have ever come into contact with—"

"However, only by increasing the temperature inside the quasi-star to hundreds of times that of the red dragon's hottest breath, can the reaction be carried out in a non-high pressure environment."

"And at such a high temperature, matter will enter a plasma state that is difficult to confine. If you want to confine it in a certain area, then you can only confine it with a magic magnetic field..."

"However, the magic power required to create such a magnetic field can be counted in massive quantities, and it cannot be maintained for a long time at all, and the efficiency must be improved."

"But if the efficiency is to be increased, it is necessary to allow the magic power to be transmitted in the form of zero-loss superconductivity in the medium. This in turn requires reducing the temperature of the outer confinement device to an absolute ultra-low temperature."

"The extreme high temperature and the extreme low temperature need to be compatible and stable in the same model, and the difficulty can be imagined."

"And all of the above are just the tip of the iceberg that allows this technique to survive stably for a long time..."

"If you want to complete the entire technique perfectly, you cannot allow the slightest error in every detail."

Ciel explained the difficulties to Renata.

And Renata also listened very carefully, keeping Ciel's statement in mind.

She knew very well in her heart——

Even in Shire's mouth, there are still many problems in the completion of this technique, and there are quite a lot of difficulties in completing it.

However, this is the last straw for this broken world.

For other worlds, people will pursue such a spell, because it itself represents an almost endless energy source, which can instantly boost the civilization process of the entire world to several steps.

However, if it cannot be achieved in a short period of time, it does not matter.

After all, the existing energy reserves of other worlds are enough to maintain the most basic development of civilization.

However, this world is different.

If there is not enough light, even if the disaster of no light at this moment has been eliminated, it cannot really solve the problem.

Perhaps, the size of the gathering place of the remaining survivors in this world will expand a little bit after losing the constraints of the dusk creatures and the lightless disaster, and the population of each gathering place will also slowly increase.

but--

That's all.

In a world without the sun, maintaining the existence of several gathering points is already the limit of the limit.

Rebuilding civilization in the true sense..

Even before the cataclysm was restored, the vibrant and beautiful world was nothing short of a fantasy.

..

Listening to Shire's words, the complex brilliance fluctuated in the beautiful pale golden eyes of the Twilight Witch.

After a long time, she slowly stared at Charles with those pale golden eyes.

"Creating that spell, even with your extraordinary spiritual power, is definitely not an easy task..."

"But you... are not actually a resident of this world, but a visitor from another plane... To you, this world is just a passing relationship."

In that small and exquisite diary, pale gold text slowly emerged.

"Why do you help me..."

"Helping the world so much..."

As the Twilight Witch who holds the power of the gods in this world, even though she is trapped in a self-seal, she still has a considerable degree of control over the world.

Looking back a bit, she knew about Shire's short past in this world.

From the moment they first came to this world, the so-called "divine magic. Atom lamp" was lowered for Aurora City, giving them a long-lasting and stable light source..

Later, the fallen sun god was destroyed with an unimaginable forbidden spell.

Even Renata, because of the self-seal, has no time to care about the lightless disaster and the creatures of the dusk, and completely solve them from the root to the tail.

At this moment.. to light up a new star for this world.

No matter from what point of view.

What Charles did..

They have already surpassed the scope of a traveler on a dimensional plane or a passer-by in this world.

..

"why?"

Charles could not help but smile.

He can understand the other party's doubts.

There has never been a free lunch in the world, and for the residents of this world, it was during the catastrophe that they deeply understood this truth.

Coupled with her own background that is too mysterious for this world, it is only natural for Renata to worry about her motives.

After all, when the gods in this world established churches and bestowed blessings, and they looked extremely stalwart and kind, no one knew that they would drag so many believers into the abyss of loss of control and madness in the catastrophe.

This suspicion—

Whether it's Aize and Anna in the City of Silver, Francis, or the legendary bone demon, in fact, they have all happened in their hearts more or less.

It's just because the strength gap between the two sides is too great, and Charles is their last straw, so they have never expressed their doubts, and they dare not speak out.

however--

As the Twilight Witch and the last protector of this world civilization, Renata directly pointed it out.

Because she knew that this dilapidated world could no longer bear the slightest accident.

..

It seems that, on the contrary, I underestimated the Twilight Witch earlier...

Charles thought inwardly.

Even though Renata's life is incomplete, and even her cognition of the world can only be imagined through a few words in books.

However, this girl sleeping in the sea of ​​stars really used her weak shoulders to bear the weight of the world's civilization and destiny.

So, what about myself——

With the spiritual power of a legendary mage, Charles examines his own heart.

"Why am I doing this?"

"On the one hand, as a human and a wizard, after witnessing the tragic fate of humans in this world and the heroic past of wizard civilization—"

"Empathy and empathy produced subconsciously."

Charles spoke slowly.

Although at the beginning of time travel, I had more of myself, in fact, I held a mentality similar to that of a game player in the game world..

However, after being brought back to the Extremely Black Tower by Weimosi, as a Black Tower wizard, after so many years of people and events——

I really have a real sense of identity and belonging to the Black Tower, to the identity of a wizard, and to this world.
