Yu Guihai arranged his family affairs, said goodbye to his family, left a lot of cultivation resources, and rushed back to his sect.

The Yu family has taken over the affairs of Beicang Mansion, and with the help of the Yun family, they are not afraid of any problems.

When passing the Tianyun Pass, Yu Guihai passed directly over the pass, not wanting to go to see True Lord Fenyan to see how unlucky he was.

It was too naive to do that, and now he just wanted to rush back to the sect as soon as possible, refine the Demon Heart Seed Pregnancy Pill, and then break through the Yuan Fei stage.

During the long journey, he did not stop at all. He flew all the way without even taking a break. He rushed back to the sect in only two days.

When Yu Guihai returned to the sect, he immediately summoned Xu Qinghe and Zhang Jinbao and inquired about the affairs of the peak. He had only been away for a mere month, and nothing major happened at all.

Then, he asked about Zhao Jianming's news and learned that this person had left the sect a few days ago and was ordered to go to the Blood Demon Prison to transport supplies.

He then ordered the two of them to inform Zhao Jianming to come back to see him as soon as possible.

Later, he told the two of them that he would go into seclusion and not be disturbed by anything. When Zhao Jianming came, he would wait in the peak.

After the two left, Yu Guihai immediately sealed the cave and placed the giant ape Wukong outside the peak master's hall to help him protect him.

In the cave, the Yin Gathering Formation was opened, and the strong Yin Qi was drawn in, forming a gray-black smoke that could not be seen. There were countless ice-cold droplets in the smoke, and it fell on the ground and splashed a piece of frost.

This is Yin Qi that is so strong that it turns into Yin water.

Yu Guihai suddenly opened his eyes. His condition had been adjusted to the best and he was ready to take action.

With a solemn look on his face, he placed all kinds of elixirs and spiritual materials in front of him one by one. There were many of these things, and they were of different varieties, but each one of them was quite precious when placed outside.

The most precious among them is the Heart of the Blood Demon King and its accompanying Blood God Flower.

In addition, it is the small bottle of soul tears.

Yu Guihai touched every elixir with his own hands and confirmed that there was no difference in its variety, quantity, and quality. Then he stretched out his hand and threw the still beating heart of the Blood Demon King into the air.

The cube-shaped demon heart exudes a strong bloody aura, which is extremely filthy. Generally, monks in the Zifu period will be assimilated by it immediately upon smelling it, and thus become a blood slave and be controlled by it.

Moreover, just hearing the sound of its beating, ordinary monks will be triggered by it and their hearts will burst and die soon.

However, this kind of power was like a breeze blowing on Yu Guihai's face, having no effect.

On top of the devil's heart, a bright and beautiful flower grows.

The flower is the size of a human head and is blood red, like a blood-stained peony, with layers of petals open. There are no branches and leaves under the petals, only a thin stem connected to a clump of slender roots, tied tightly like blood vessels.

Into the heart of the devil.

This is the Blood God Flower.

Yu Guihai looked at it for a moment, but without stopping, he fired countless spells one after another, and a pale yin fire rose out of the air, wrapping the demon heart and the Blood God Flower in it, burning fiercely.

He has already learned the first half of the Netherworld Refining Art to a perfect level, and is very familiar with the method of refining the Devil's Heart Seed Pill. Although he has not practiced it before, he has already reached the level of perfection and is fully confident.

The Yin Fire burned, and powerful bloody demonic energy immediately erupted from the Demon Heart and the Blood God Flower to resist the Yin Fire.

The collision between the two did not create a sensation like a thunderous explosion, only a gentle breeze and drizzle.

This is due to Yu Guihai's incomparable power of control. The Yin Fire he manipulates is just right, and he can refine the bloody demonic energy in the Demonic Heart and the Blood God Flower.

Time passed little by little, and Yu Guihai maintained the same posture, constantly wielding various mysterious spells with his hands, patiently refining the Demonic Heart and the Blood God Flower.

This process cannot be rushed. Once the refining speed is too fast, the demonic energy in it will not be completely eliminated, which will ultimately affect the quality of the finished elixir.

And a low-quality elixir was definitely not what Yu Guihai wanted.

The effect of the Devil's Heart Pregnancy Pill depends on its quality, and what Yu Guihai wants is the highest quality and perfect pill.

One day, two days, half a month, one month

Yu Guihai has been refining the Demon Heart and Blood God Flower.

This process is quite arduous and consumes a lot of money. An ordinary monk of the same level would definitely not be able to endure it. Both his spiritual thoughts and spiritual power need to be replenished many times.

But Yu Guihai is different. His spiritual thoughts and spiritual power are far stronger than those of the same level. Not only can he persevere easily, but he also has the energy to upgrade and add points every day, using the elixirs and spiritual elixirs he learned from the second half of Netherworld Alchemy.

The refining methods such as magic weapons are upgraded to perfection.

On this day, Yu Guihai suddenly opened his eyes and stared into the void in front of him.

The demon heart has now shrunk to the size of an egg yolk, and the Blood God Flower has also shrunk to the length of a finger. The flower that was originally the size of a human head is now only the size of a fingertip.

An extremely weak bloody mist emits from the demon heart, which is constantly annihilated by a layer of imperceptible pale flames wrapped around it.

Finally, there was a moment of void, and the weak beating of the devil's heart stopped completely. The last trace of bloody devilish energy rose out, and was immediately burned into the void by the pale yin fire.

There seemed to be an unwilling wailing sound coming from the void, and then the roots of the bright red Blood God Flower squirmed, and actually penetrated into the Demonic Heart.

"Finally done!"

Yu Guihai breathed a sigh of relief. The hard work of sitting around these days was not in vain. He had completely eliminated the bloody demonic aura from the Demonic Heart and Blood God Flower, and they were ready for the next step of refining.

Then, he waved his hands and cast countless mysterious spells. The yin fire in the void skyrocketed and burned violently. Spirit materials flew into the yin fire like moths flying into the fire. In an instant, they were refined with impurities, leaving only one

Pour a little bit of essence medicine into the devil's heart.

The devil's heart does not reject anyone who comes, absorbing all the essence, its size gradually increases, and even resumes its slow beating.

Dong Dong Dong~

Every time it beats, a trace of bloody demonic energy will be produced.

This shows how strange the devil's heart is and how powerful its desire for survival is. Even if its own devilish energy is completely refined, it will be reborn once it is nourished.

Moreover, the elixir refining was in the middle at this time, and all the newly generated bloody demonic energy was contained in the demon heart. Yu Guihai could not activate the Yin Fire to directly refine it, otherwise all the previous efforts would be wasted.

However, Yu Guihai was not in a hurry, and just kept putting various spiritual materials and elixirs into it, supplying a large amount of medicinal essence to the demon heart for it to absorb.

As the demon heart absorbed the essence of the medicinal power, the bloody demonic energy it transformed skyrocketed, and soon even exceeded the demonic energy it carried before.

All these demonic energies are concentrated in the Blood God Flower. The Blood God Flower shrinks in the Demonic Heart and is constantly transforming. The petals bloom one after another, slowly revealing the stamen hidden in the center.

Yu Guihai's eyes were like lightning, his senses were fully opened, and he was constantly staring at the movement of the Blood God Flower.

The moment the Blood God Flower fully bloomed, a small blood-red human figure emerged from the stamens.

This villain only has humanoid limbs, but no facial features. It exudes an extremely powerful bloody demonic aura, and its aura has risen to its peak.

Suddenly, a small opening opened at the top of the devil's heart, and the villain seemed to be born from it.

"This is the moment!"

With a thought in his mind, Yu Guihai stretched out his hand like lightning, grabbed a small jade bottle, and poured it towards the devil's heart!

A wisp of transparent water fell gently, instantly passed through the small opening, and poured down along the head of the blood-red villain.

Soul Tears, specially designed to cleanse and neutralize bloody evil spirits.

Chichi~

A large amount of blood-red aura rose from the place where the villain's body was washed with water, and was immediately burned into nothingness by the violent Yin Fire.

squeak squeak

The villain let out a vague scream, and the body washed by the water turned into a pure white color!

When the clear water flows over the little man's body, the whole little man has completely transformed into a pure white man.

The demon heart, which had absorbed countless medicinal essences, was completely transformed into a square, transparent object.

Yu Guihai's face was filled with joy, he had successfully refined the perfect quality Devil's Heart Embryo Pill!
Chapter completed!
