At this moment, more than fifty kilometers away from the Yun Family.

On top of a desolate mountain, there was an unremarkable cave. Fang Ling was sitting inside it, slowly adjusting his breathing.

When fighting with the black bearded middle-aged man, Fang Ling was caught off guard and killed him easily. And because the other three did not share the same mind, they fled the moment they revealed their defeat. Therefore, Fang Ling did not waste any energy. However, the battle with the Yun Family's Grand Elder was quite dangerous.

If Fang Ling didn't use the True Essence Cauldron and Chi You in his battle, just the Cloudfinch Fire alone would have made it difficult for Fang Ling to deal with him. Moreover, the Skylark Fire was a flame the Yun Family's Grand Elder had meticulously trained for over a hundred years.

This method was quickly broken by Fang Ling, causing the Yun Family's Head Elder to be shocked, but he still used the item he had obtained at the auction, the talisman that produced the fog.

This talisman was called the Heaven Decaying Rune, and was worth thousands of Spirit Stones. It could create a fog that blocked one's spiritual awareness for a period of time, but it was immune to the user, allowing the user to sneak attack or escape.

The Yun Family's Grand Elder was very unlucky, thinking that he could kill Fang Ling with a single strike. However, he did not expect that Fang Ling's physical body was strong, and that refining the Baleful Yin Heaven Technique had increased by a lot.

Although the Yun Family's Great Elder injured Fang Ling with a single strike, it was not a fatal blow. Fang Ling had dealt with it and killed him with a lightning-like method.

Half a day later, Fang Ling slowly opened his eyes. The injuries he had suffered previously were now completely fine, and his internal force had recovered.

With a tug on his waist, several storage bags appeared before him. Picking them up and inspecting them one by one, Fang Ling revealed a faint smile between his brows.

In Yun Zizai's storage bag, Fang Ling obtained dozens of low grade spirit stones, a few mid-grade spirit stones, and a bottle of pills that could help to increase his mana.

As for the black sideburns middle-aged man, he only had a few low-grade spirit stones in his storage bag. As for the other three, they were not too different from each other.

Just looking at the Spirit Grasses, Fang Ling could tell that these Spirit Grasses still had a hint of moisture in them. It was obvious that they had just been picked, and the years of these Spirit Grasses were hundreds or even hundreds of years old. Amongst them was an extremely rare medicinal pill for Fang Lingkang to break through to the Foundation Establishment stage, one of the most precious spiritual herbs recorded in his Spiritual Arts. With these main ingredients, Fang Ling only needed to find a few supplementary spiritual herbs and he would be able to refine such a pill.

Even though Fang Ling did not attempt to break through his Taoist foundation until he reached the second level, it was still possible for him to make preparations in advance.

In addition to these spiritual herbs, the Yun Family's Great Elder's storage bag also contained thousands of low-grade spirit stones and dozens of mid-grade spirit stones. Fang Ling also found a piece of stone that seemed to have bright spots on it.

He quickly flipped his hand and a book appeared in his palm. The book was made from demon beast skin and was obtained from Daoist Master Hao Yun's cave. At that time, he had obtained a hundred thousand different types of books, and even though he did not read them all, he had read more than half of them.

Flipping the book to one of the pages, there was what seemed to be a piece of ore, speckled with bright spots. It was extremely similar to the object in Fang Ling's hand. Fang Ling compared it over and over again and finally determined that this piece of ore before him was indeed an extremely rare and precious treasure.

This ore was several times more precious than the Sky Falling Divine Iron. If those existences who had surpassed the Pure Yang level were to find out that this ore existed in the Haoyun World, they would definitely cross over to fight for it.

It was because this piece of ore was actually the Sun God's Core!

The items were all condensed after the sun had fallen, and the appearance of such items meant the death of a divine sun. This item was more than enough to refine a top quality dao tool, and if there was enough celestial spiritual energy, it was possible to even refine a celestial item!

Although the True Essence Cauldron had recovered some of its power through the repair process of the Meteorite Divine Iron, it was useless for Fang Ling right now. After all, right now, Fang Ling was facing the existence of the Fa Li realm, and these existences had a higher level of existence. At this moment, the True Essence Cauldron was already unable to purify the energy essence of the other party.

The Sun God's Core in front of him was without a doubt the best material!

The Sun God's core turned into a stream of light and merged into the flames, floating up and down. After continuously using the flames to refine it for a day, even Fang Ling's face was pale. Only then did the Sun God's Pill emit a thread of energy that contained a large amount of fire energy.

As this wisp of energy entered the broken true essence array, in the next moment, the true essence furnace suddenly shook. Chi You, who was secretly refining the lark fire, was startled. After he checked for a while, he was shocked to see the Sun God's core floating in the air.

Back then, Chi You and the War God had fought for eighty thousand rounds, shattering countless small worlds and even destroying countless suns. Therefore, Chi You naturally knew what was in front of him.

To Chi You, the Sun God's core was nothing. However, with Fang Ling's current cultivation level, it was beyond his expectations.

A strange light flashed across Chi You's eyes, and a thought suddenly emerged in his mind. This brat might really be able to help him quickly recover his cultivation.

Under the pale face of Fang Ling, the True Essence Cauldron suddenly trembled and floated in the air. It was completely red on the surface, like a red-hot iron, and the runes engraved on it seemed to be alive, as it continuously rotated and moved about.

In the blink of an eye, the aura of a primary treasure was emitted, and then this aura rapidly rose. In a short period of time, it had reached the high-grade treasure rank!

"This!" "I never thought that I would underestimate the power of the Sun God's Core. It took me an entire day to refine it with the aura of the Sky Opening Demon God, and only then did it release a sliver of my aura. But it was this sliver of aura that caused the True Essence Cauldron to undergo such a change!"

Looking at the True Essence cauldron, Fang Ling could not help but exclaim.

"Haha …" Brat, do you think the Sun God's Nuclei are cheap? If it wasn't for the fact that you're cultivating this Demon God's Heaven Opening Technique, the Sun God's Divine Core wouldn't have changed even if you used fire to refine it for hundreds of years.

It has to be said that even for those Pure Yang Juniors, to refine a piece of Sun God's Core, would require a hundred years of hard work. "

Chi You sneered when he heard Fang Ling's words. Hearing this, Fang Ling chuckled. He did not know this point, even Spiritual Master Hao Yun would not understand it, as he had only recorded down some heavenly and earthly treasures. As for physical items, he had never seen them before.

And this book was called the Universal List of Heavenly Mystical Materials. The Sun God's Pill was ranked third among them. It was a rare heavenly material in the world!

The first was actually a demonic insect called the Heaven Travelling Insect. It was a demonic insect that was constantly travelling between the heavens and earth. It usually lived together with two extremely powerful and terrifying insects that could enslave the strong. This was similar to Fang Ling's slave imprint. This demonic insect was said to be able to refine the Primaltwin and was something that all powerhouses would want.

And the second was the Five Elements Spirit Pearl.

There were several hundred types of spirit materials on the top of the Heavenly Ranking, and not only there were ores, spirit herbs, demon beasts, and even human cultivators! These cultivators were all favored by the heavens and possessed an extremely unique cultivation system. In front of these systems, their bodies such as Qin Yuyan's Three Yang Body and Qin Yuqin's Nine Yin Body were extremely ordinary.

For example, Fang Ling remembered that there was a type of person with a body that was born with a Supreme Bone in their body. As a cultivator continued to grow, the bone would increase its power, and in the end, it would be able to contain the laws of heaven and earth!
