Dongwu City.

In the City Lord’s Mansion, apart from the entire underground being hollowed out, the Tree of Life in the middle is also isolated by a huge glass dome, and at the far west, there is currently a rift filled with an undead aura.

Since the space of the City Lord’s Mansion is still limited, only the ravine representing the world’s entrance from Diane’s valley was brought in.

And this ravine looks like a crack leading to another dimension, giving a sense of oppression.

Yuan Tang glanced at the Tree of Life shrouded in alchemy materials, feeling somewhat satisfied.

"As you said, the gods might descend at any moment, the world could recover, and the True Gods might not necessarily return, so... Diane cannot be indulgent, many times, a little more effort might be what keeps you alive."

He looked at the Tree of Life with some sentiment in his eyes: "The current prosperity... seems somewhat false, when facing gods, we... are nothing..."

"Things depend on people, we are all still young." Baiyi smiled and said: "Maybe, beyond the taboo lies the path to the Ancient Gods?"

"Difficult..." Yuan Tang glanced at the Undead Celestial Abyss, space fluctuations flickering around him: "Be careful."

As if thinking of something, his magic power surged, leaving a book in the void: "Your spatial ability is quite good, perhaps this can help you with something."

Baiyi caught the book, and then paused for a moment, it contained Yuan Tang’s understanding of space, this top-notch genius.

Baiyi flipped through it, deep in thought, as if... he had the intention to specialize.

After putting it away, Baiyi looked towards the entrance of the City Lord’s Mansion, where Luoning had brought back many men and women, all with trepidation and unease in their eyes, but more so with curiosity.

These people, numbering around three hundred at a glance, were those who helped manage and take care of Diane’s daily life at Diane Manor.

With the appearance of Lady Alena, the trepidation in these people’s eyes vanished, and they eagerly asked questions.

Baiyi did not pay much attention, knowing the rooms in the City Lord’s Mansion were probably insufficient, but they could expand it slightly, as the surrounding official buildings were also planned to be rebuilt.

Compared to the current Inner City, the two streets outside the City Lord’s Mansion had become somewhat outdated, making rebuilding necessary.

Issuing some orders to the construction department via Zero, Baiyi entered the laboratory and began his busy work.

About two days later, another glass-like dome covered the Celestial Abyss representing the Undead World.

This kind of glass is called [Elemental Layer], a somewhat advanced alchemy material, capable of isolating single or multiple types of magic power.

In other words, if the layer contains the auras of life and undead, then this dome would only isolate life and undead elements, allowing other elements to move freely through this material.

Alchemists like to use them to create unique environments for experiments or to cultivate certain alchemy materials.

After finishing these tasks, Baiyi took some equipment and left Dongwu City, arriving at a towering mountain nearly ten thousand kilometers away.

He glanced at the sky, and from the Demon Realm, took out a radiant Sun Crystal Core.

This was the final version of the Sun Crystal Core after four enhancements, with a diameter reaching one meter. 𝙛𝓻𝒆𝒆𝒘𝙚𝓫𝙣𝙤𝒗𝙚𝓵.𝙘𝙤𝙢

Its mere appearance turned the night sky into day, as if a sudden sun had appeared, causing unease.

Baiyi didn’t pay much mind; this one-meter Sun Crystal Core would eventually become a ten-centimeter Solar Hymn.

This would be the fifth compression, and the explosion diameter of this Solar Hymn would reach ten thousand meters, not counting the shockwave.

The energy tier might have reached the level of a High-Tier Legendary, or even higher.

He had promised Metheus to accomplish this, but Baiyi never intended to disclose the creation method to the Federation.

The reason is simple, the conditions for forming the Sun Crystal Core are too stringent.

Sunlight—extracted into liquid—compressed into crystal—higher purity liquid extracted—inserted with inert substances for further compression—transformed under the Heart of the Fierce Sun for over five hundred years—to obtain the Sun Crystal Core.

The Heart of the Fierce Sun is crucial, and he never intended to give it to the Federation, so there was no need to provide the creation method.

As Baiyi activated the instruments to start creating the Solar Hymn.

Buzz~

A special wave began to spread madly, causing animals throughout the mountain range to shudder, and the night insects’ chirping suddenly halted.

The surrounding silence was terrifying.

This silence only lasted for three seconds before animal roars, insect cries, flapping wings of birds, and chaotic footsteps resounded through the night.

They fled frantically from this tallest mountain peak, running madly into the distance, with tigers and deer running side by side, eyes devoid of each other, filled only with unyielding fear.

Baiyi ignored the chaos and continued his creation, pondering why he had to travel so far instead of making the Solar Hymn in his own laboratory?

A common Solar Hymn is just an explosive, which can be made anywhere.

But with a special skill point and a Sun Crystal Core, the collision of top knowledge and materials would make anyone within the explosion or shockwave radius experience a destiny-level sting.

It is a fear that is hard to isolate.

In Baiyi’s Demon Realm, there is a common Solar Hymn with a diameter exceeding thirty meters, and even creating that had ignited such a destiny-related crisis.

No matter how much he reined in his aura at that time, it still made people in the Kingdom of the Dark Night World feel sheer terror.
