What does my ancestor's pregnancy have to do with me, a mere servant?

After sending the message, Lin Yuan stood up and stretched.

He turned and walked towards the weapon-refining room.

On the bluestone platform, there are still four sets of materials for the Profound Yin Extinction Thunder.

Lin Yuan took a deep breath and formed a hand seal.

The Earthly Fiend Netherfire surged from his palm, spreading out above the stone platform with dark flames and swirling blue halos around its edges, instantly lowering the temperature of the entire weapon-refining room to freezing point.

One day later.

Lin Yuan put away the Earthly Fiend Netherfire.

On the refining platform, four jet-black orbs floated silently, their surfaces occasionally flashing with dark red lightning patterns. An aura of extreme cold and volatile energy intertwined, as if they were about to explode at any moment.

The four Xuan Yin Extinction Thunderbolts have all taken shape.

Each of the five Profound Yin Extinction Lightning Bolts was equivalent to a full-force attack from a late-stage Golden Core cultivator.

The simultaneous explosion of all three would cripple even a top-tier Golden Core cultivator, if not kill them.

Five detonated simultaneously—

He carefully placed the five thunder pearls into a specially made jade box, and then sealed it with three layers of restrictions.

Although this thing won't explode on its own, he doesn't want to experience the feeling of "self-production and self-consumption" if it gets damaged in the storage bag.

Lin Feilu came by that day.

After spending two hours on the bluestone bed, Lin Yuan ruthlessly drove the person away.

It wasn't that he didn't want to stay longer, but time was of the essence. The secret realm was about to open, and he still had a lot of things to refine, cultivate, and prepare.

When Lin Feilu left, her clear, cold eyes were filled with grievance.

Just then—

A subtle fluctuation emanated from the Six Yin Soul-Locking Array.

It wasn't triggered by human intervention, but rather by a living creature that intruded into the array's sensing range.

Lin Yuan raised an eyebrow. He formed a hand seal and extended his divine sense.

Outside the formation, a small, crimson figure was squatting on a rock, its tail swaying leisurely from side to side.

Lin Yuan opened a gap in the formation.

A moment later, a bright red fox darted in.

It's not very big, only about a size larger than a typical house cat.

But its fiery red fur gleamed eerily in the moonlight, and the demonic energy emanating from its body was extremely strong, clearly indicating that it was a demonic beast comparable to a mid-stage Golden Core cultivator.

The fox had a bulging storage bag in its mouth, and its vertical pupils were unusually lively as it stared at Lin Yuan for a couple of seconds.

His eyes held a condescending, scrutinizing gaze.

The next instant, Shen Guiyan's cold voice came from the fox's mouth.

"Don't let me down."

The fox tossed its neck and threw the storage bag on the ground.

Then, with a gust of wind, it turned and darted into the forest. Its bushy, crimson tail flashed in the night and disappeared in the blink of an eye.

Lin Yuan stared at the direction the fox had disappeared in, his lips twitching.

He raised his hand and took the storage bag into his palm.

Divine sense probed in.

Good guy.

The three pieces of Netherworld Ghost Bone were each the size of a human head, and their surfaces were filled with a ghostly aura so dense it was almost tangible.

The two pieces of the lightning-struck wood in the Yinyuan Abyss are dark red, and one can vaguely hear the deep roar of the lightning sealed within them.

Various high-grade ores were piled up like small mountains—Frost Iron Essence, Mysterious Yin Stone, Soul-Devouring Silver Sand, Netherworld Mysterious Crystal…

There are also dozens of excellent spiritual materials for refining Body Tempering Pills and Spirit Feeding Pills.

Finally, there was a blood-red jade slip.

Lin Yuan took out the jade slip and placed it between his eyebrows.

Information flooded into my mind.

Nine Netherworld Locking Heaven Formation.

A simplified version of the ancient formation.

To fully set up this formation, twelve formation flags and one core formation plate are required.

A complete arrangement of this formation can trap and kill late-stage Golden Core cultivators.

Even if a Nascent Soul cultivator is trapped inside, it will take a lot of effort and time to escape.

However, the requirements for crafting array flags and array plates are extremely demanding—array flags require the crafting skills of a fifth-grade weapon craftsman, and array plates require the array formation expertise of a fifth-grade array master to complete.

Both are indispensable.

"Not bad, not bad. Old Granny Shen is quite generous." Lin Yuan put away the jade slip, rubbed his chin, and started planning his schedule for the next two weeks.

Refine the Body Tempering Pill. Combined with the Hundred Refinements of Mortal Bones Technique, push the physical body's strength to the mid-stage of the Mortal Transformation Realm. Shen Guiyan still needs to inspect the goods; this is the bottom line.

Simultaneously, refine Spirit-Feeding Pills to feed the Spirit-Devouring Demonic Insects. During breaks in cultivation, refine the array flags and array plates for the Nine Netherworld Locking Heaven Array. Also, draw several stacks of high-level talismans.

Li Yang will likely come to face her for arduous training. She took drugs to break through her cultivation level, which will definitely cause problems with her foundation. He will have to take responsibility for cleaning up the mess.

Li Yang will likely come to train with her face-to-face. Since she's using drugs to break through to a higher realm, her magical power will definitely be unstable, and her foundation will certainly be in trouble.

He has to clean up the mess and, incidentally, farm some attribute points.

Kill two birds with one stone.

Clarify your thoughts.

Lin Yuan took out the alchemy furnace and placed it in the center of the stone platform.

The materials for the five Body Tempering Pills were added into the mixture in batches.

The body tempering pill is not difficult to refine. With his level of fifth-grade alchemist, refining multiple batches at the same time is a piece of cake.

Black flames rose.

The Earthly Fiend Netherfire completely enveloped the alchemy furnace, casting eerie shadows on the stone wall with its ghostly blue halo.

Lin Yuan closed his eyes and let his consciousness sink into the alchemy furnace.

The tedious yet fulfilling period of seclusion began.

Time flies.

For the next seven days, Lin Yuan's life was compressed into an extremely simple cycle—

Alchemy. Consuming elixirs. Cultivating the Hundred Refinements of Mortal Bones Technique. Feeding insects. Crafting array flags. Drawing talismans.

Lin Feilu would come almost every day.

Seven days later.

Black Crow Mountain Training Room.

Lin Yuan sat cross-legged in the center of the bluestone floor.

His body was enveloped in thick, dark, earth-fiend fire.

The Hundred Refinements of Mortal Bones Technique was running wildly.

A layer of dark golden metallic sheen appeared on the surface of her skin. That sheen flickered, rising and falling dramatically with the rhythm of her breathing.

The muscles bulged and contracted under the skin, producing a dull rumble, as if something inside was struggling to break free.

He had already completely refined the medicinal power of the Body Tempering Pill, transforming it into streams of pure essence of heaven and earth that merged into his body.

Lin Yuan suddenly opened his eyes.

The black fire receded into his body.

He exhaled a breath of stale air.

Only one final obstacle remains to reach the mid-stage of the Transcendent Realm.

If one's Qi and blood become even more abundant, a breakthrough can be achieved in a maximum of two days.

Lin Yuan stood up. His bones made a crisp cracking sound.

He stretched his shoulders and neck, feeling the surging, almost overflowing, energy within his body.

He walked out of the training room and pushed open the stone door of the spirit beast room.

A faint buzzing sound wafted over.

The Soul-Devouring Demon Worm, which was originally only the size of a grain of rice, has now grown to the size of a soybean.

Feeding with the Lingling Pill for seven days yielded immediate results.

Its outer shell is jet black and shiny, gleaming with a cold metallic sheen under the light of the lamp.

Its edges were as sharp as knives, as if they could slice through the air. The fangs on its mouthparts were clearly visible, small yet terrifyingly sharp, exuding a ferocious aura.

Lin Yuan took out a handful of refined Spirit Feeding Pills from his storage bag.

Raise your hand and scatter it.

Hundreds of spirit-devouring demonic insects instantly went berserk. The cacophony of flapping wings created a continuous din.

They gathered together and swarmed forward. In less than three breaths, more than a dozen top-grade Spirit Feeding Pills were completely devoured.

Lin Yuan looked at the group of insects who were still not satisfied.

"He ate quite a lot."

Seven days is still too short. Two months would be enough to mature them to adulthood. Once released, even Golden Core cultivators would have to give way.

But in its current state, coupled with the Blood-Inducing Pill, it can barely be considered a trump card once it enters the Taixu Secret Realm.
