In a quiet room that was two meters square, Chu Yao sat cross-legged with his eyes closed.

A variety of rings shone around her. This was a magic circle that Bai Yuejian had set up in advance, with various effects, such as calming the mind, gathering spirits, warding off evil spirits, and so on.

There were four things in front of Chu Yao: a storage bag, two small jade bottles containing elixirs, a small bone shield, and a leather robe.

There is no need to mention the storage bag, as it contains all the demon pills that Chu Yao has collected in the past three years.

The two bottles of pills were refined in advance to assist the golden elixir in overcoming tribulations.

The shield and the robe, these two items are top-grade magic weapons that Chu Yao made using the bones and furs of countless alien insects, used to resist thunder tribulations.

According to past experience, it would be great if there were top-grade Tribulation Pills.

However, it was obviously not easy to find the materials for refining the Tribulation Pill on Lingyuan Star. Given the limited conditions, these were the best things Chu Yao could prepare.

The Golden Core Realm is the second major hurdle in cultivation. Even though Chu Yao has passed it once before, he still has to be cautious.

Our ancestors spoke of the Golden Elixir Great Dao. If foundation building is the threshold to spiritual practice, then the Golden Elixir is the threshold to the Great Dao. Stepping into the Golden Elixir is a true transformation, a true immortal-like being.

She sat in meditation for a long time, her spiritual energy circulating in her body, her essence, energy and spirit gradually becoming full, and her momentum gradually rising.

The moment his condition reached its peak, Chu Yao's eyes suddenly opened wide, like a sword drawn from its sheath, ready to strike.

With a flick of his fingers, two pills, one blue and one white, flew out of two small jade bottles and were held in Chu Yao's mouth.

The Dark Spirit Technique was activated, and the cold spiritual energy that filled the limbs and meridians gathered towards a point in the body.

Within the quiet room, a gust of spiritual wind surged like a hurricane. The spiritual energy of heaven and earth swirled around Chu Yao.

Bai Yuejian, who was guarding outside, saw his eyes move and whispered to Xiaoye who was also waiting beside him: "It has begun."

Watching the Jindan tribulation at such a close distance was a rare opportunity for her, which would be beneficial to Xiaoye's future practice, so Bai Yuejian called her out of seclusion.

The spiritual wind within the quiet room grew stronger, but the spiritual energy within it seemed to be drying up. Chu Yao's body seemed to have turned into a black hole, greedily devouring everything it could.

The golden elixir can also be called the holy fetus.

Gold is a hard and indestructible substance; elixir is a perfect, bright and pure substance without any flaws.

Condensing the Golden Elixir is both easy and difficult. The ease lies in simply gathering a little bit of spiritual energy, but the difficulty also lies at this stage.

This pitiful amount of spiritual energy from heaven and earth is not enough.

The two pills that Chu Yao had held in his mouth before had been used up, so he took out two more and put them in his mouth.

Then she waved her hand, and hundreds of demon pills flew out from the storage bag.

These demon pills of various shapes and colors, which had long been refined by the spiritual fire, floated in the air, as if turning into a river of pills, circling above her head.

As soon as Xiu spitted out a word, a large amount of spiritual fire covered the Dan River. The densely packed demon pills turned into a dazzling glow, which contained a terrifying and powerful spiritual power.

With a wave of her hand, the "river" of spiritual power surged towards the spiritual platform in Chu Yao's body, and her whole body seemed to be coated with a layer of golden light.

Chu Yao frowned, her body trembling slightly due to the impact of the massive spiritual power.

This process is very painful. Although the pill in her mouth can reduce the pain a little, she still has to bear the majority of it herself.

She could only bear it. At this moment, Chu Yao had to concentrate on guiding this huge spiritual power. If she was not careful, the consequences would be disastrous.

The Nether Spirit Art was running at its peak. The spiritual power surged into the three fields in the body, and was poured into the acupuncture points and meridians throughout the body. Then it returned to the Dantian and turned into the original spiritual power needed to make the elixir, repeating over and over again.

Under the impact of spiritual power, his limbs and bones seemed to be wailing, shaking and unable to bear the weight.

But Chu Yao knew that this was a necessary hurdle. So far, everything was under her control and she was handling it with ease.

There was a strong wind blowing in the quiet room. If the spiritual vortex just now was a breeze, it could be called a storm now.

The spiritual power storm spread wildly on the hill. Lu Xiaoye's face turned pale under the sweep of this huge force. Bai Yuejian waved her hand to summon a ray of spiritual light, and her complexion looked better.

In the Dantian, above the Lingtai, the rolling cyclone gradually condensed into shape, and a clear purple golden pill had taken shape.

But something strange happened.

A black shadow appeared beside the golden elixir that was gradually condensing into shape!

Chu Yao's heart skipped a beat; the thing she didn't want to see happened.

She had actually anticipated this kind of thing, because of the special nature of the Nether Spirit Art.

Before Chu Yao established his foundation, formed his elixir, and formed his infant, he had practiced the Netherworld Technique passed down by his master. Even if he practiced again, he would just be going through the old path again.

But the Mingling Jue was created by her by combining the Cunling Jue! She also didn't know what variables would appear in this technique.

Moreover, the change came so suddenly that no suspicious signs were found when he was refining Qi and building the foundation. But at the critical moment of forming the pill, such a thing happened.

But Chu Yao didn't panic. Since she had chosen this path, this disaster was inevitable.

She separated a wisp of her spiritual consciousness and probed towards the "black shadow".

It is about the size of a thumb, like a wandering soul in a transformed form, and seems to have been born with the golden elixir.

Wandering soul? Remnant spirit? Little ghost?

Chu Yao fell into a brief thought, but he had never heard of anyone who had a ghost accompanying him after forming a pill.

She stared at the little ghost with her spiritual sense for a long time.

This thing has the shape of an earthly ghost, but it seems to have the potential to be a sky ghost - because Chu Yao felt a certain consciousness coming from it, but this consciousness was confused, like a newborn baby.

It seemed to have no ill intentions, just wandering around the golden elixir, absorbing some of the scattered spiritual power to strengthen itself.

This little ghost looked extremely fragile. Chu Yao felt that he didn't even need to use any strength. A single push of his spiritual sense would make it disappear into thin air.

Uh...why not just let it go for now.

Since this little guy doesn't pose much of a threat to me for the time being, I might as well keep him in my body.

Anyway, I have plenty of ways to deal with it. Maybe raising it up will be a good thing?

Chu Yao felt relieved and devoted herself to the condensation and growth of the golden elixir.

In the blink of an eye, three days and three nights passed. The fluctuations of spiritual power circulating outside began to become smaller and smaller, and the cave became much calmer.

But Chu Yao knew that this was the "calm before the storm."

As the technique was practiced, the golden elixir took shape. A thumb-sized round purple pill floated up and down in the dantian with the breath, shining brightly.

The black shadow grew bigger and bigger, and Chu Yao felt that there seemed to be a mysterious connection between the two of them.

As soon as she thought about it, the little guy would travel around in her body, just like another kind of life-saving magic weapon was born in her body, except that this magic weapon was alive.

Just when the golden elixir was about to be completed, an indescribable sense of oppression rolled in from all directions, as if to crush it.

The highlight is coming.
