Chapter 1743 The Secret of the Black Demon Embryo Body

Zhang Xuan pondered for a moment, then nodded and said, "Now is certainly not the best time to explore such a vague and dangerous mystery. The most urgent task is to digest the existing gains, consolidate and improve our strength, in order to deal with the imminent external enemies. The matter of the Immortal Path can be listed as a long-term goal. When our Nine Domains have a stronger foundation and a deeper understanding of the outside world, we may be able to find a more reliable way to explore it."

Ancestor Tian Shi agreed, saying, "Instead of wasting our strength on the unpredictable mysteries of the Holy Ancient, it's better to concentrate our efforts on crushing the visible enemies that are about to appear. Once we've eliminated external threats, stabilized our territory, and eased resource pressures, we can then consider other options."

The three reached a consensus.

In the Immortal Gourd Realm, there is Hei Zi's exclusive Nine Netherworld Demon Palace.

Located at the eye of the convergence of Yin energy in the Immortal Gourd Realm, this place was transformed by Zhang Dawu through a personal array, perfectly blending the original Yin energy and death energy with the rich demonic essence, forming an excellent holy land for demonic cultivation.

The mansion is shrouded in darkness, with only nine ancient ghostly flames floating in the air, reflecting the eerie patterns on the cave walls that resemble the worship of countless demons.

Hei Zi sat cross-legged at the core of the Ten Thousand Demons Returning to Origin Array at the deepest part of the mansion, surrounded by black mist, with ferocious demonic shadows faintly visible floating and appearing on his body.

His face still retained some of the dark, chubby features of his childhood, but the childishness in his eyes had long been worn away by time and magical powers, replaced by a deep, reserved, and complex temperament.

His path to growth was, in the eyes of the cultivators in the Immortal Gourd Realm, strangely smooth.

With a top-grade spiritual root, a demonic physique, the strong support of the realm lord, the heavy water weapon at his side, and the hidden fragments of the Demon Emperor's scroll pointing directly to the Great Dao.

All resources and opportunities seem to be readily available.

Easily break through to the Nascent Soul and Divine Transformation stages.

Then, after the great battle eight hundred years ago, she quietly stepped into the Fusion Realm in just seven hundred years, becoming the first of Zhang Xuan's many children, besides Mengmeng, to break through to the Fusion Realm, and seemingly the easiest one at that.

His cultivation speed even puts some veteran cultivators to shame.

Only Kuroko himself knew that beneath his seemingly smooth path lay a shocking secret that had accompanied his growth.

This secret originated from the demonic fetus that coexisted with his demonic body and was connected across endless dimensional barriers.

From the moment he fused with that drop of black, high-level true spirit blood in his childhood and awakened his demonic avatar, an extremely faint passage opened deep within his soul.

This passage connects to a distant and unfamiliar interface.

At first, the passage only transmitted fragments of thoughts intermittently, like the deepest nightmare, often disturbing the mind of young Hei Zi, making him unable to sleep at night, and his temperament became increasingly gloomy and withdrawn.

The situation only changed when he entered the Foundation Establishment stage and began to formally cultivate the True Demon Spirit Forging Technique.

He remembers that day clearly.

When he circulated his cultivation technique and drew upon the first wisp of pure demonic energy within his body, the long-dormant passage deep within his soul suddenly trembled!

A surge of true demonic energy, purer and more domineering than his own demonic essence, rushed in, instantly cleansing his limbs and bones, washing away all the impurities in his hard-won demonic essence, and forcibly correcting the operating path of the True Demon Spirit Forging Technique to a track closer to its origin.

At the same time, a weak and confused consciousness, yet filled with a natural sense of closeness, like the first cry of a newborn baby, clearly rang in his mind: "Hungry... in pain... it's dark outside..."

That was the first time the demonic fetus had a true spiritual connection with him.

Since then, Hei Zi has realized that his Demonic Embryo Body is not just a simple innate physique.

He and that demonic fetus seemed to have always been in a state of symbiosis in a foreign land.

As Hei Zi's cultivation improved, his connection with the demonic fetus became clearer, and their communication became smoother.

They share an understanding of the true path of the demon.

Hei Zi transmitted the insights from the "Fragment of the Hidden Demon Emperor" he received from his father, the true meaning of the Four Symbols Demon Palace he comprehended from the Boundless Heavenly Scroll of the Heavenly Demon Abyss, and the essence of various demonic scriptures collected from the Immortal Gourd Realm to the Demon Fetus through the mental channel.

Meanwhile, the Demon Embryo fed back to Hei Zi the incredibly pure and ancient true demonic essence he possessed from that realm, as well as an extremely efficient method for tempering the true demonic body.

Even more incredibly, this cross-interface connection can actually achieve a certain degree of material exchange.

Although the cost is enormous, each exchange requires a massive amount of soul power and magic essence.

Hei Zi once passed on a wisp of demonic essence that he had painstakingly condensed.

Upon receiving the demonic fetus, the demon was overjoyed and sent back a pure essence of primordial demonic energy, which directly loosened the bottleneck in Hei Zi's cultivation that had been stagnant for a long time.

The demonic fetus also passed on a piece of dark gold bone fragment the size of a fingernail but as heavy as a mountain. Kuroko integrated it into his own bones, and his physical strength immediately soared.

They were like two prisoners trapped in different cages, separated by endless void, warming and supporting each other, exchanging insignificant items from their respective worlds.

Kuroko sees the Demon Embryo as her only kindred spirit.

This is his deepest secret and reliance.

At least half of his superior magical understanding, pure magical energy, and powerful physique compared to others of his level can be attributed to this gift and exchange across interfaces.

The demonic fetus provides very little description of its own situation, only repeatedly mentioning darkness, a cage, an endless supply of materials, and regularly distributed cultivation resources.

All Kuroko knew was that the demonic fetus seemed to have been imprisoned in a fixed place since it became conscious, and was forced to perform some kind of monotonous and bloody work.

Process the corpses of various powerful demons and extract useful materials from them.

"Brother Hei, I dealt with a big one today."

The demonic fetus's telepathic communication was always intermittent, tinged with weariness and numbness.

"His bones were so hard, with strange patterns on them, like they were breathing. I followed the rules, picked out the bones, and carefully separated them. A lot of blood flowed out; it was golden and burned my hands. But I secretly saved a tiny drop of essence for you."

Kuroko felt a pang of pity, but she also knew that this was the only way the demon fetus could obtain extra resources.

He could only cultivate even harder, passing on more insights into the demonic path, hoping to help the demonic fetus become stronger and escape that terrible predicament as soon as possible.

Time passed in this clandestine exchange and mutual assistance.

Hei Zi successfully formed his core, became an infant, and transformed into a deity. Moreover, thanks to the pure true demonic essence and body tempering methods provided by the demonic fetus, his foundation was incredibly solid, and he encountered almost no major obstacles when undergoing tribulation.

When he returned from the Heavenly Demon Abyss, he comprehended the deeper meaning of the "Fragment of the Hidden Demon Emperor's Scroll," and with the help of a special demonic soul resonance from the demonic fetus, he successfully fused the Heavy Water Weapon with his own demonic power, and his strength increased by leaps and bounds.

However, just a hundred years ago, Kuroko successfully passed the Heavenly Tribulation of Integration and officially entered the Integration Stage. Not long after, the previously stable communication suddenly experienced violent fluctuations.

"Brother Hei, it seems I'm about to advance." For the first time, the Demon Fetus's voice trembled noticeably, not with joy, but with boundless fear.

"I can feel the rules of the cage changing, making the materials I'm given stronger and stronger. Yesterday, I peeled off the inner world of a complete magical immortal from a material, and it was still faintly glowing."
