239: Chapter 239 [Emperor's Edge Wields the Thunder-Slaying Heavenly Sword], Experiment

Countless souls were cast into the Reincarnation Lake, shedding their original forms and using their true spirits to be reincarnated as humans once again; even the infants born in these past few years have shown visible growth in their innate talent.

In his perception, the concepts of the netherworld, reincarnation, and rebirth within the original netherworld reincarnation lotus have grown rapidly since the appearance of Ghost Immortal cultivators.

Because a portion of the Ghost Immortal cultivators have returned to the mortal realm, concepts related to the netherworld, reincarnation, and rebirth have spread throughout the entire Human Federation.

Wang An's Yin Spirit, dressed in imperial robes, sat at the head of the Heavenly Palace, investigating the various newly born things within this Netherworld Realm.

"Reincarnation Stone, Yin Spirit Iron, Yellow Springs Water, Other Shore Flower..."

"It seems the perfection of these laws still relies on the wisdom of the infinite sentient beings."

Feeling that the seeds of the 'Law Nature' of the netherworld laws within the netherworld reincarnation lotus were already extremely luminous and plump, as if ready to burst forth at any moment and transform into Golden Nature.

Wang An felt a sense of joy in his heart.

The more Golden Nature he possessed, the faster his own cultivation and knowledge would grow, and the faster his cultivation speed would become.

Afterwards, he came to the third underground level, the Thunder Hell, and saw that the entire world of the Thunder Hell, once vast, had shrunk by a circle, and the earth had become denser, reaching a thousand miles.

In the center of the Thunder Heaven and Earth, a fire lotus was above, and a sea of thunder was below, intertwining with each other.

In the middle, a blinding light flickered at the core, sometimes transforming into a three-inch small sword, sometimes into a wisp of airflow; this was the flying sword that had been forged for five years, incorporated with nine types of metal ores possessing minor spatial attributes, and refined in shape and quality three times.

Sensing the arrival of Wang An's Yin Spirit, the flying sword flew up and down with great excitement, stirring up the thunder and fire of the great formation within the world.

It was evident that the "Thunder Fire Demon-Refining and Treasure-Nurturing Formation" set up by a Grandmaster-level expert could no longer refine it to a higher level.

With a movement of his mind, having established a close connection with the flying sword, the small black sword immediately received the command; the originally jet-black sword instantly turned transparent and gradually hid within this space.

Even his Yin Spirit thought could barely detect its flight trajectory; in an instant, it flew before him, circling happily.

"Stop for a moment and let me observe you properly."

A thought was transmitted.

The flying sword hovered in the air, its entire body black with no reflection, yet at the tip of the blade, there was a bright light condensed from extremely sharp sword energy and sword intent, which even Wang An dared not touch lightly.

Because that was the accumulation of the many sword intents Wang An had comprehended over these years, which, after years of tempering and forging, had transformed into a faint "Sword Edge Law Nature."

In the internal core, he had also added the "Autumn Emperor Blade" minor divine ability as a power augmentation; for general Tier 2 High-Grade defenses, this flying sword could shatter them instantly.

After observing for a while, Wang An proceeded to cast the refining Dharma seals, establishing a deeper mental connection.

"Hum."

The flying sword trembled slightly, and a bolt of black lightning was triggered, covering the blade.

Wang An did not feel any danger from this lightning, but the moment it appeared, even the demons outside the Thunder Hell seemed to sense a natural enemy; the chaos of their original onslaught immediately quieted down, as if they were afraid of something.

Seeing this, Wang An moved his mind, and the black lightning immediately retracted, causing the demons to rush back into the Thunder Hell.

His Yin Spirit thought entered the flying sword, and a feeling of mental communion arose spontaneously; from then on, this flying sword achieved a deep connection with him, where his thoughts were immediately followed by action.

At the same time, he also understood the abilities of this flying sword.

This flying sword had cost him numerous resources and time, forged with the most top-tier methods, and he had refined two Law Natures into it: "Sword Edge" and "Thunder Law."

"Sword Edge" could sever all defenses; unless the opponent possessed restrictive methods or higher-level laws, they would be decapitated in the blink of an eye.

"Thunder Law" used lightning to specifically judge all evil ghosts and spirits; it had an extremely strong restraining effect on souls, spiritual bodies, and Yin-attribute creatures, and all powers involving such would be suppressed in the face of this sword.

He admired the flying sword in detail.

Its entire body was dark, with a single point of light at the tip of the blade; it was about 10cm long and 3cm wide, yet it emitted the aura fluctuations of a Tier 2 High-Grade item.

Addressing the flying sword, Wang An said softly.

"From now on, I shall call you the 'Imperial Blade of Thunderous Demon-Slaying Heaven'."

The flying sword gently vibrated the space, emitting a buzzing sound in response to the name Wang An had given it.

After completing the naming, the Heavenly Sword, at his summons, escaped into his Violet Palace to be nurtured carefully.

Meanwhile, in the Bronze Human Race territory, Taiyi Yutian, East Sea, Island No. 17.

This place no longer felt as desolate as it did before he arrived; a Five Elements formation domain blocked the chaotic external energy one by one, smoothing and stabilizing it as it entered this place.

In the center of the island, the spatial law streams overflowing from the Heavenly Eye of the high-altitude world crystal wall, under the interception of the large energy formation domain, flowed into a 10m-sized celestial sphere in the center.

Below the celestial sphere were various forging tools; a pouch woven from the skin of a Void Serpent was placed on the platform beneath the celestial sphere, brown scales covering the entire pouch, with the opening of the pouch facing the celestial sphere.

"Experiment 230 record: Material, Void Serpent skin; Spatial Rune Module No. 1999; injecting 10 strands of spatial law streams; spatial energy, 5 base units."

"Experiment start."

As soon as Wang An finished speaking, the bronze-colored celestial sphere glowed with blue light, countless runes were activated, and mixed with the law streams and spatial energy, they instantly condensed into lines and were struck into the Void Serpent pouch below.

The detection machine on the side immediately reported based on the feedback.

"Spatial Rune Module No. 1999 operating normally."

"Spatial energy connection smooth."

"Law and Void Serpent skin solidification complete."

"Micro-space activation successful; measured spatial volume: 1 cubic meter."

"Spatial detection stable; self-sustainment started."

Having reached this step, Wang An did not relax; he had succeeded in maintaining micro-spaces more than once before.

But the space would collapse during the final step of retrieving or placing items, rendering the entire experiment a failure, requiring all rune modules to be redesigned and the entire experiment to be started over from scratch.

It was only by experiencing countless such material experiments that he could achieve the current results.

And this was the shortcoming of biological spatial materials: their spatial stability was extremely poor.

He could only test one material at a time.

However, to manufacture spatial equipment at a low cost, he could only use this method.

After all, the cost of spatial equipment made using spatial ores was at least 1 million Dharma Essence Crystals, which was 10 times more expensive than warships of the same level.

And even then, it was a seller's market where one couldn't even buy them.

Wang An used the power of his Yin Spirit to pick up this primary spatial storage pouch; after refining it, a one-cubic-meter space appeared in his Yin Spirit, and the surrounding spatial barriers were extremely stable.

A fist-sized stone was collected into it and left to rest in the space; there was only a slight fluctuation, which was automatically adjusted and calmed by the rune module.

Seeing this, Wang An let out a long sigh of relief, a look of joy appearing on his face.

"It is finally finished."
