Masterful Application of the Domain

In the Light Source Star System, an orange-red star releases endless light and heat.

Countless planets, large and small, orbit this massive celestial body, the most eye-catching of which is a blue-green life-bearing planet.

Suddenly, a strange cloud of atoms spreads out from that life-bearing planet.

The atomic cloud is hazy, shimmering with flowing, brilliant colors under the sunlight. Centered on the Light Source Star, it rapidly diffuses in all directions, forming a spherical region with a diameter of 100,000 kilometers.

A moment later, the mist-like atomic cloud gradually turns transparent, entering a stealth standby state.

Light Source Star, Civilization Temple.

The core of the "energy shield," resembling a sapphire, floats in mid-air within the temple, rotating in sync with the planet while emitting a faint blue glow.

"Universe technology is truly miraculous."

A look of deep emotion appears on the aged face of Master Zhen Li.

When inactive, this energy shield is merely a cloud of atoms dispersed in space, having absolutely no impact on the Light Source Star. Normal spacecraft entering or leaving will face no issues at all.

"The price is quite high, after all. If we were to buy a spaceship, an A9-level one would cost less than 10,000 Chilian Coins."

Yu Duan stands beside Master Zhen Li, followed by Kun Zhu and Shen Jian. He looks hesitant, as if there is something he wants to say.

Master Zhen Li smiles and looks at Yu Duan: "It seems your trip into the universe was quite fruitful this time; otherwise, Kun Zhu and Shen Jian wouldn't be acting like this."

"To be honest, Master, I have joined a faction in the universe..."

Yu Duan briefly explains his situation regarding joining the Beiming Sacred Land to Master Zhen Li.

"According to the agreement, in about 90 universe days, personnel from the Sacred Land will arrive at the Light Source Star to pick me up."

The Light Source Star is not Earth; it is just a very ordinary life-bearing planet, so there is no need to hide things. Thus, Yu Duan will depart directly from the Light Source Star to head to the Beiming Sacred Land.

"A genius sacred land of a high-level universe nation—this is a good thing, a very good thing!" Master Zhen Li nods repeatedly, looking quite excited.

As long as Yu Duan himself does not run into trouble, the Light Source Star and all his kin will benefit from this in ways beyond measure. A civilization that could previously be destroyed by a single supernova can now truly join the society of universe civilizations.

"Competition in the Sacred Land is fierce. I certainly won't be able to attend to internal affairs of our people, so I leave everything to you, Master, and my two brothers."

Yu Duan certainly won't leave the Light Source Star to fend for itself.

After all, since transmigrating, he started with the standard "parents sacrificed to the heavens" opening, and his ability to grow and rise smoothly was due to the civilization's social welfare system.

Humans are not unfeeling creatures; how could he have no heart?

Therefore, after careful consideration, Yu Duan intends to provide 1 million Universe Coins as a development fund for the civilization, to be managed by Master Zhen Li and the other two.

Moving forward, tasks such as purchasing planets will not require Yu Duan to run errands personally, giving Master Zhen Li and the others a chance to have more contact with the universe.

It takes three months for the Beiming Sacred Land's ship to reach the Light Source Star, and the same amount of time to take Yu Duan to the Sacred Land.

With a round trip taking about half a year, he can use this time for cultivation.

Previously, when Yu Duan was grinding the progress bar of the Book of Causality, he was forced to be confined within a cramped single-person spacecraft.

Beyond simply grinding the progress, he could only try to comprehend and ponder the mysteries and techniques of his domain and combat skills, without even having the chance for live combat practice.

But now that he has upgraded his equipment, while grinding progress, he can log into the Virtual Universe to study and engage in combat training.

During the Beiming Sacred Land's Planetary Level assessment, Yu Duan felt that his actual combat skills were far too poor.

If not for his Domain Level foundation, he would have been at the very bottom among the Planetary Level Fighters of major factions.

After all, the combat experience of an Apprentice Level and the combat techniques of a Planetary Level capable of flight are in completely different dimensions.

Furthermore, Yu Duan's own combat skills are lacking; the Dawn Blade is simply too inferior.

Fortunately, purchasing combat skills and secret techniques from the Virtual Universe is very convenient.

Virtual Universe, Killing Field.

The vast hall seems endless, its dome resembling a vast sea of blood, with a brilliant "blood drop" shining brightly within it.

Inside the hall, there are only about ten thousand people scattered about, and Yu Duan's figure in the corner is completely inconspicuous.

"As for the realm, I'll just set it according to my own parameters. However, the force exertion technique must reach 10 times, and the combat experience should be maxed out."

"For combat skills, I'll use the Morning Dawn Nine Blades and the Floating Light Glancing Shadow movement technique I just bought."

A light screen visible only to him floats before Yu Duan, displaying the interface for customizing his opponent.

The Morning Dawn Nine Blades and the Floating Light Glancing Shadow movement technique are third-tier Fighter combat skills Yu Duan just purchased.

Among third-tier Fighter combat skills, these two belong to the most common level, costing a total of over 70 billion Chilian Coins, about the same as a Force Weapon of the same level.

"Boom!"

After Yu Duan finishes his settings, the original Killing Field instantly transforms into a vast, boundless desert. Yu Duan, clad in red and gold-patterned armor, floats in mid-air holding a golden curved blade.

At the same time, a figure similar to Yu Duan emerges, holding the same long blade and wearing the same armor.

"Whoosh!"

A brilliant golden-white domain instantly spreads out from that figure, and then, in the next instant, it vanishes abruptly.

To be precise, it hadn't disappeared; rather, it had ceased to maintain its spherical shape, transforming into a brilliant white-gold "aura" that swirled around that figure.

Whoosh!

A radiant golden glow tore through the sky, vaguely leaving behind a trail of blurred golden afterimages in mid-air.

The speed was too fast—so fast that Yu Duan barely had time to react before he was instantly defeated.

"A domain... can be used like this?"

Yu Duan's figure condensed and reappeared, a look of shock surfacing in his eyes.

Is this what it means to have the "combat experience" option maxed out in terms of domain application?

The essence of a domain is actually the perfect resonance of the soul, body, will, and origin energy, entering an incredibly marvelous state of harmony.

In this state of harmony, different energies fuse together to form a brand-new power.

When this power radiates outward, it can influence space-time and subsequently suppress enemies—that is a domain!

Yet, this is only the most superficial and common application of a domain; it works well for bullying the weak, but when facing an existence of the same level, that is not necessarily the case.

The opponent just simulated by the Virtual Universe had pushed domain application to the limit.

It utilized this fused power perfectly within its own attacks and movement techniques, without a single shred of extra power leaking out—it could be called divine.

"Very good, this is my goal."

The Book of Causality is used to "grind" insights into domains, laws, and the like.

As for Yu Duan himself, he will focus on comprehending application techniques, as well as the training and mastery of secret arts.

Both of these are key factors in increasing combat power.
