Xia Wei pondered for a moment before making a decision and raising his hand.
The colorful halo formed by the Gods Base behind him appeared, slowly rotating.
An invisible rhythm arose throughout the Heavenly Realm, and wisps of pure white airflow appeared in the sky above his head, forming a swirling cloud vortex in the blink of an eye.
This was World Power from the Demon Slayer World.
World Power is an energy higher than divine power, an omnipotent force formed by the fusion of all the world's powers.
Of course, this 'higher than divine power' refers to his current divine power; if his divinity were to ascend to Lv. 2, then his divine power would be on par with the Demon Slayer World's World Power.
If his divinity reached Lv. 3, the quality of his divine power would surpass the Demon Slayer World's World Power.
The 'surpass' here refers to a qualitative transcendence, not an omnipotent one, as World Power is the product of the fusion of all the world's powers, and also the world's life force.
"Overthinking is pointless for me. It's better to first transform the current environment; future matters can be 're-created' when needed."
The capabilities of low-level World Power are limited; it cannot achieve things beyond the Demon Slayer World's comprehension.
In short, a world's World Power can only accomplish what is possible within that world.
"Right... if I use World Power to activate an Authority..." Xia Wei's eyes lit up instantly as he thought of this.
Without hesitation, he directly injected World Power into 'Fantasy Materialization'.
Buzz!
The entire Authority seemed to come alive, and a rhomboid, colorful mark instantly appeared on Xia Wei's forehead.
An ancient and sacred mirror emerged above his head, and colorful light illuminated the entire Heavenly Realm, as if it had instantly transformed into a small sun.
"As expected of World Power, it directly maximized the Authority's power! Even things with some mystery can be permanently brought into reality."
World Power forcibly raised the power of a Lv. 1 Authority to Lv. 2, and a wisp of World Power was equivalent to the divine power stored in an entire Lv. 1 divinity.
"This way, I can bring the Heavenly Realm I imagine into reality."
With a thought from Xia Wei, the entire Heavenly Realm instantly transformed into a sea of flames.
Boom!
Except for the temple at the very center, which housed the "World Nexus," all the floating fragments of ruins in space melted into fiery red magma.
This magma then gathered together to form a floating island the size of Shikoku Island, the smallest of Japan's four main islands.
Xia Wei continuously squandered World Power, transforming the Heavenly Realm.
Since World Power comes from the world and is a renewable resource, and he doesn't have to pay anything to obtain it, he felt no remorse at all.
"In the future, various worlds will be incorporated into the Gods, and their cultures will differ, so architectural styles will need to be integrated."
The architectural characteristics of Christianity, Shintoism, Chinese mythology, Greek mythology, Norse mythology, and other mythologies were all integrated.
As a God, his thinking and aesthetics far surpassed those of humans; the architectural characteristics of all civilizations were integrated almost perfectly.
Human aesthetics are fundamentally universal; humans from any civilization coming here would find a sense of familiarity in these buildings.
The prototype of a massive sky island appeared in the center of the Heavenly Realm, and buildings of varying sizes, imbued with sacred colors, were rapidly materialized.
While constructing buildings, numerous smaller floating islands were also materialized.
These small floating islands would later serve different purposes.
For example, workshops for forging divine artifacts, or places to install 'gates' leading to other worlds.
Xia Wei hadn't forgotten that there were still many talented people in the Demon Slayer World, such as the swordsmiths in the Swordsmith Village. After being granted Blessing, they would likely acquire skills in forging weapons.
In the future, the weapons for the many dependents of the Gods would need to be custom-made by them.
He, as the Main God, couldn't possibly project weapons with his Authority for the dependents to use, could he? Wouldn't that make him a babysitter? That would be fatal for the development of the Gods.
While Xia Wei was constructing the Heavenly Realm, the Demon Slayer Corps swordsmen were also busily carrying out their tasks.
Yaozai Ubuyashiki had disbanded the Demon Slayer Corps; 'disbanded' was just a change of name. He had properly arranged for the swordsmen who desired a peaceful life, ensuring that each swordsman could live a prosperous life.
Those who wished to remain were temporarily arranged by him to serve as guards in the Shinto family's main house. This would certainly be useful in the future for tasks like journeying to various worlds to save humanity.
He also hoped that these swordsmen, who had contributed to slaying demons, could receive the Blessing of Lord Xia Wei.
He simply wished that the remaining swordsmen could contribute their strength to Lord Xia Wei; as for Lord Xia Wei bestowing Blessing upon the swordsmen, he dared not even imagine it.
He was well aware that Lord Xia Wei's ability to bestow Blessing upon him and his wife was due to the Hashira's good fortune.
Only true heroes could receive Blessing and become candidates for Godhood.
With his single skill, he was likely destined to not become a candidate for Godhood.
Therefore, he only hoped to do more for Lord Xia Wei in his lifetime, even if Lord Xia Wei didn't need him.
But if Lord Xia Wei doesn't need you, do you just not do it? That would be a great disrespect to Lord Xia Wei.
Ubuyashiki Residence's graveyard.
After Kibutsuji Muzan completely disappeared, Shinobu Kocho felt a pull in her heart urging her to come here.
She knew this must be Lord Xia Wei's guidance to her.
As soon as she entered the graveyard, she saw a familiar transparent figure standing before her sister's tombstone, looking at her gently.
"Sister..." Shinobu Kocho's nose stung, and hot tears instantly rolled down from her eyes.
"Eh? Can Shinobu see me now?" Butterfly Kanae was surprised.
After she died and was buried four years ago, she was so worried about her straightforward younger sister that she didn't reincarnate.
She also found that she couldn't leave the graveyard, becoming a localized spirit, only able to leave once her lingering attachment disappeared.
In these four years, Shinobu had shown obvious changes every time she visited her.
She had even forced herself to become gentle, which worried Kanae even more.
"Sister!" Shinobu Kocho cried as she ran over, not touching her transparent sister, knowing that her sister was a soul and could not be touched.
"Don't cry, don't cry, Shinobu, Sister is here." Kanae gently raised her hand to caress her sister's head, but stopped the next moment; she couldn't touch anyone.
"Sister, let me tell you, a lot has happened recently..." Shinobu Kocho wiped away her tears while sobbing, recounting Xia Wei's appearance, the Blessing, and Kibutsuji Muzan's eradication.
"So, the God last night was Lord Xia Wei? Shinobu is so lucky, I'm even envious, Sister," Kanae said gently.
She had clearly witnessed the descent of the Destiny Fantasy Great God last night.
She just never expected that her sister would become a dependent of that God.
Even as a soul, it stimulated her quite a bit.
