Light Domain

"Whoosh!"

A brilliant white stream of light emerged from Yu Duan, his entire body seemingly turning into an afterimage as he flickered within the gravity chamber.

With the Leap of Rosy Clouds movement technique activated, his leg strength amplified sevenfold, pushing his speed amplification to over three times its base. Combined with his Light Ray Manifestation innate ability, his speed increased significantly once more.

Normally, the running speed of a Planetary Level powerhouse is around 1 kilometer per second, but with Yu Duan pushing his movement technique to the limit, his speed easily exceeded 5 kilometers per second.

Of course, under the 500-fold gravity load of the Light Source Planet, he certainly could not reach that speed.

"A movement technique at the level of Unity of Heaven and Man—although it only provides a small boost to speed, it greatly enhances agility and significantly reduces energy consumption!"

Splendid light swirled around Yu Duan. As his figure flickered, he seemed to truly transform into the morning light piercing through the darkness, maneuvering and shifting within the gravity chamber.

A moment later, fine beads of sweat seeped from Yu Duan's forehead.

The energy cost of executing a movement technique at full power was already high, and with the burden of the 500-fold gravity of the Light Source Planet, the consumption skyrocketed far beyond 500 times.

"It seems the gravity chamber is no longer enough; to grind through the progress, I need..."

Yu Duan sensed the changes in his body and instinctively let his consciousness seep into the Book of Causality, immediately noticing something amiss.

On the Book of Causality, the other characters faded away, leaving only a single line of archaic text: Cost repayment in progress, full-power execution of movement technique [Leap of Rosy Clouds] for over 1 million kilometers, current progress: 294.7 kilometers.

In the palm-sized space of the gravity chamber, Yu Duan had executed his movement technique at full power, maneuvering dozens of laps, which amounted to just over 20 kilometers.

"Does the actual repayment efficiency change based on the environment?"

Yu Duan hurriedly conducted an experiment, executing his movement technique at full power while keeping a close eye on the change in repayment progress on the Book of Causality.

About a minute later, Yu Duan confirmed the change in efficiency: in the current gravity environment, executing the movement technique for 1 kilometer was roughly equivalent to 12 kilometers under the standard gravity of the Light Source Planet.

"The consumption in the gravity chamber is indeed high, requiring more rest time, but even if the actual efficiency isn't exactly 12 times, it will certainly be significantly improved."

Yu Duan's eyes shifted; this change was similar to playing a game and discovering that the boss's health bar had suddenly shrunk by a large chunk.

There was nothing more to say—it was time to grind.

"Number One, I am going to cultivate in the gravity chamber. Prepare food and energy replenishment potions for me according to my physical state and physiological needs."

As Yu Duan finished speaking, the voice of the intelligent assistant sounded: "Understood, the requirements of Celestial Yu Duan have been recorded."

In the blink of an eye, nearly 10 days passed.

In the spaceship's main control room, Master Zhen Li, Kun Zhu, and Shen Jian were discussing what identity they should adopt to make contact with the cosmic civilization.

However, they had not yet reached a consensus in the short term.

Shen Jian raised his right-hand optical computer and casually checked on Yu Duan, who was still cultivating in the gravity chamber.

"It's been 10 days, and Yu Duan is still grinding... No wonder he possesses movement techniques and combat skills at the Artistic Conception level."

Shen Jian's tone was no longer as gentle as usual, but rather filled with a sense of admiration.

To become a powerhouse, talent is only the basic condition; willpower and hard work are also indispensable factors.

Master Zhen Li's aged voice sounded: "Indeed, Yu Duan's comprehension is stronger than both of yours; only Kun Zhu possesses insights at the Artistic Conception level."

Unlike the terrifying comprehension of Earthlings.

Among Apprentice Level Earthlings, more than one genius with Artistic Conception-level insights had appeared.

As for the people of the Light Source Planet, they are born at the first stage of the Apprentice Level, and their physical talent is actually much stronger than that of Earthlings. But apart from Yu Duan, only Kun Zhu possessed Artistic Conception-level insights on the entire planet.

"Yu Duan's Artistic Conception insights are deeper than mine; every movement of his seems more... in harmony with nature?"

Kun Zhu did not know about the so-called Unity of Heaven and Man.

After all, according to common knowledge in the universe, the levels of combat skills and secret techniques are divided into four tiers: Basic, Artistic Conception, Domain, and World; there is no Unity of Heaven and Man.

But Kun Zhu could simply perceive that when Yu Duan practiced his movement technique, the rhythm and Artistic Conception were more unique, though he did not know how to describe it.

At this moment, inside the gravity chamber.

Yu Duan's figure shuttled rapidly through the high-gravity environment, accompanied by the splendid radiance emitted by his light ability, forming streaks of fleeting afterimages.

"Finally finished grinding the progress bar."

Yu Duan panted heavily. While he appeared to be resting, his consciousness entered his internal space.

The archaic text on the Book of Causality changed once again.

[Dawn Artistic Conception] Light-type Artistic Conception, level: Unity of Heaven and Man. Can pre-advance 'First Layer Light Domain' insights, repayment cost: bathe in sunlight for 100,000 hours.

[Dawn Blade] Self-created martial art, level: Unity of Heaven and Man. Can pre-advance 'unranked' level domain application techniques, repayment cost: execute 1 million full-power strikes with the blade.

[Leap of Rosy Clouds] Self-created martial art, level: Unity of Heaven and Man. Can pre-advance 'unranked' level domain application techniques, repayment cost: move at full speed for a distance of 1 million kilometers.

[Daybreak Force] Self-created force-exertion technique, level: 7-fold force, can pre-advance 8-fold force, repayment cost: execute the maximum force 8,000 times.

"Domain application techniques? It seems that from the Domain level onwards, insights and techniques cannot be improved simultaneously."

As a transmigrator, Yu Duan naturally understood that profound attainments in domains and laws, as well as the application of domains and laws, were key factors in determining combat power.

So-called secret techniques are actually application techniques for insights, divided into five levels: unranked, ordinary, top-tier, peak, and ultimate.

"For me, the most important thing in the early stages is the improvement of domains and laws. As for application techniques, I'll set them aside for now."

Ever since Yu Duan confirmed the general background of the world he was in, he had been eager to integrate himself into the universe.

Much information remained inaccessible, especially regarding the timeline; he had no idea which era he was currently in, or whether Luo Feng had already risen to prominence.

"Advance the comprehension of the First Layer Light Domain!"

Boom!

It felt as if a massive bell had been struck right beside Yu Duan's ears, shaking his consciousness until it blurred.

A surge of profound comprehension flooded Yu Duan's heart. In this moment, he felt as if he had become the darling of light and stars, bathing in the corona of a star, wandering and playing within it, existing in harmony with the very source of light.

As the comprehension poured into his consciousness, the fluctuations of Yu Duan's aura began to change accordingly.

His body, force, will, and soul entered a state of great harmony, as if they had completely merged into one.

Not only that, this state of great harmony seemed to be resonating with the nature and universe outside, causing different powers to fuse and form an entirely new force field.

"Whoosh!"

A hazy, dreamlike, misty white field spread out in all directions with Yu Duan at its center.

That dim, misty white domain flickered slightly, as if responding to the myriad stars in the vast night sky, magnificent and dreamlike.

The hazy domain cast Yu Duan's figure in a flickering light, making him appear as if a divine kingdom from mythology had manifested in the mortal realm.

"So this is a domain... what a wonderful resonance."

Yu Duan felt his influence over space and the surrounding environment; the light within the range of his domain bent and flickered according to his own will.
