Spirit Ruins Realm, Zhongtian Continent!

Lin Yun and Qi Lin hugged each other under a big tree, only to see that this big tree was about a million zhang high, connected to the sky at the top and connected to the ground at the bottom!

The roots of the tree pass through the nine shades of the Yellow Spring, bordering the chaos!

The treetops pierce through the Endless Void to reach the Land of Chaos!

The body of the tree is majestic and upright, the branches are luxuriant, the crown is like a canopy, the roots are entrenched in intricacies, and the most bizarre thing is that the big tree presents a kind of color, which seems to encompass all the colors and blend them, and the mystery is unpredictable.

Under the majestic and huge body, there are endless laws and paths, and countless avenue runes are constantly evolving on the body of the tree, forming one after another laws of heaven and earth!

This is the World Tree, the product of the Three Thousand Great Dao Laws of the Spirit Ruins Realm!

The legendary World Tree is the ancestor of all trees, the source of all worlds, the world tree that has grown to the extreme, its fruit can evolve the world, and its branches and leaves can evolve the spiritual root of heaven and earth!

Of course, Lin Yun's world is far from reaching that level, it is just a seedling now!

Perhaps, after the Spirit Ruin Realm grows into a Middle Thousand World, this World Tree will have the ability to evolve into a small world, but now, it's still a little short!

Lin Ling'er once did an experiment and used the branches of the World Tree to cultivate a new World Tree!

She succeeded and failed, the second-generation World Tree does have the ability to town-bounded the world, but its growth speed and potential are not as good as the first-generation World Tree!

The ancient tree of life in the elven world is one of her experiments, even so, that ancient tree of life is also worshiped as a sacred tree by the elf clan, which shows how precious the world tree is!

"Chaos Furnace, Come!" Lin Yun shouted, and a simple black gold furnace fell from the top of the World Tree, on which flowers, birds, fish, insects, sun, moon and stars were carved, and there were mysterious avenue law lines appearing.

A trace of chaotic qi overflowed from the mouth of the furnace, although there was only a trace of it, but it was as heavy as a thousand pounds, crushing the earth cast by the dark iron!

The Chaos Flood Furnace is a strange thing to create, a treasure of the day after tomorrow, and it is the instrument of the town boundary of the spirit ruin world!

And this time, he needs to use the Chaos Flood Furnace to refine a furnace of Dao Dan, he can refine ordinary pills at his fingertips, but Dao Dan can't, Dao Dan is also known as the Dan of Laws, which can make people comprehend a law of heaven and earth, with an ordinary Dan furnace, he is not absolutely sure!

In the immortal world, those who have crossed the tribulation and become immortals are also called heavenly immortals, and those who have mastered the power of the law are called true immortals!

If you want to become a true immortal who has mastered the power of the law, there are two main ways, one is through the cultivation of various exercise books, and from the long years of cultivation, you will continue to comprehend all things in heaven and earth, and finally there may be a chance to comprehend the power of the law...... The second is to use spiritual materials containing the power of some laws of heaven and earth to refine them into Dao Dan suits, so as to comprehend them.

In fact, even in the immortal world, there are very few alchemists who can refine the Dao Pill, and a Dao Pill will even cause Taiyi Golden Immortal-level characters to go crazy!

At this time, his doppelganger Lin Tian was sleeping in the origin of the Spirit Ruins Realm, but Lin Yun had no intention of waking him up!

Because it's not time yet, he hasn't broken through the Da Luo Jin Immortal, the true spirit has not been unified, and the clone may not be able to be anti-guest-oriented, although the probability is negligible, but it can't be considered, he and the Heavenly Dao clone have been separated for too long, so long that the connection between the two has weakened!

As Lin Yun's mind moved, the chaotic fire in the chaotic oven began to ignite, and the chaotic-colored flame, as if it did not carry any temperature, could burn all things in heaven and earth!

Immediately afterwards, Lin Yun took out a large number of immortal elixirs, all of which were not less than ten thousand years old, and

Most of them are spatial attributes, and the most precious of them is the tens of millions of years of space spirit fruit picked in the Void Island!

Qi Lin on the side watched quietly, she was very curious about the alchemy refiners, but she was not an immortal cultivator, so she couldn't experience it herself!

Her physique is very special, or the human beings of the supergod universe have a very special physique, which is suitable for practicing martial arts, but not for cultivating immortals!

This time, Lin Yun brought her here just to change her physique and fulfill her dream of cultivating immortals!

Lin Yun threw the immortal elixir into the Chaos Furnace, and as soon as the Chaos Fire burned, all the impurities were burned out, leaving only a ball of crystal liquid!

Although these immortal elixirs are very precious, compared to the refining of Dao Dan, they are just dispensable auxiliary materials, and they are purified and cleaned as soon as they are mixed with pure fire!

In a short time, thousands of groups of medicinal liquid were purified, and Lin Yun stored them for later use!

Next is the main ingredient, tens of millions of years of space spirit fruit plus a piece of tea with the law of space enlightenment, these two heaven and earth spirit extracts, there are no impurities in themselves!

Especially that tens of millions of years of space spirit fruit, its own existence is a great miracle, if it weren't for the mysterious laws of space, coupled with the protection of Lin Tian, the Heavenly Dao, it would be impossible to cultivate it for so long!

What he needs to do is to use Chaos Fire to refine the spatial laws in these two spiritual creatures!

With a single movement of Lin Yun's hand, a fist-sized white fruit emerged, it was the space spirit fruit, flying into the Chaos Flood Furnace!

Under the refining of the chaotic fire, the surface of the white fruit gradually crystallized and became rounded.

Eventually, the white fruit melted, revealing the golden silk threads inside, emitting bursts of fluctuations in the power of the laws of space.

In this way, Lin Yun controlled the Chaos Fire and began to refine it in earnest!

In the end, all the golden threads were refined, and a magic decision was made, sealing it, and the liquid that the fruit melted into was also put into a jade bottle for later use!

He waved his hand to summon the tea with the law of space, and used the same method to refine the law of space inside, seal it for later use!

After the preparations were completed, Lin Yun's fingers moved slightly, and a stream of red light emerged, and thousands of balls of refined medicinal liquid flew up and entered the Chaos Flood Furnace!

When the liquid medicine entered the furnace, it immediately boiled, and some white smoke appeared inside.

Lin Yun's face was solemn, and he held the trick in his hand, controlling the chaotic fire in the furnace.

These liquids are not simple things, they are all refined from tens of thousands of years of immortal elixirs, each group of liquid medicine is a huge energy body, thousands of groups of liquid medicine react at the same time, even he has to be careful!

Fortunately, the Chaos Flood Furnace has a bonus to alchemy, and the success rate of using the Chaos Flood Furnace for alchemy is 100%, and there is a 50% chance of benign mutation!

Of course, this refers to ordinary pills, and the words of Dao Dan can't be counted like that!

A day later, thousands of balls of liquid medicine turned into a mass of white gelatinous substance, and at this time, Lin Yun put the prepared spatial laws into it!

Although the two spatial laws come from different materials, there are many overlaps, because these two materials are cultivated in the same world!

What Lin Yun has to do is to separate the overlapping parts and combine the different spatial laws into a new spatial law!

Fortunately, his comprehension of the laws of space is not bad, otherwise, he really can't complete this process, just like that, most of the days have passed!

Lin Yun didn't pause too much, raised his hand with one hand, and took out all kinds of spiritual fluids again

There are three light divine water, water of life, etc., all of which were thrown into the furnace by him!

In this way, time passed little by little, and most of the day passed in a blink of an eye.

The materials prepared by Lin Yun had all been put into the furnace, and at this moment there were ten white pills the size of a dragon's eye in the furnace, one of which was as smooth as jade, and the remaining nine had a somewhat uneven surface.

Under the scorching flames of chaos, the white pill turned slightly, emitting bursts of gray aura.

In front of the Chaos Flood Furnace, Lin Yun's face was solemn, sweat was faintly visible on his forehead, and his breathing seemed to be a little unsmooth.

He underestimated the difficulty of refining Dao Dan a little, and at this moment, he realized that he was a little wrong by refining it himself.

The refining of Dao Dan is completely different from ordinary pills.

Although the general pills are ever-changing, the process is basically to refine various medicinal materials to form a liquid medicine, and then condense these liquid medicines into a pill type, and finally come out of the oven.

But refining Dao Dan is different, refining Dao Dan lies in the control and fusion of laws, which happens to be what he lacks!

To be honest, he rarely controls the laws to fight, and he can comprehend so much of the power of the laws, all thanks to the experience of wandering in the chaos!

Although the chaos is dangerous, there are also countless opportunities, and the scene he sees in the chaos has turned into the foundation of his current cultivation!

……

Boom, boom, boom......!

The sound inside the Chaos Flood Furnace became louder and louder, and the thunder roared, and the various heaven and earth spiritual qi here were fused and stirred.

The various colors of light emitted from it also became more and more dazzling, and gradually merged into one, turning into pure gold.

Lin Yun's eyes lit up, and he knew that the scene in front of him was a sign of being about to become a Dan.

It took him three days to refine this furnace Dao Dan, and this was still when he used the Chaos Flood Furnace.

If you use an ordinary immortal alchemy furnace, I'm afraid it will take a few months!

The magic trick in Lin Yun's hand was like a raging storm, and the golden light in the oven became more and more brilliant, condensing into various shapes such as dragons and tigers and Caixia from time to time, but there was no trace of taste, not even a trace of aura overflowing.

Roar, roar, roar!

At this moment, the sound coming out of the furnace suddenly changed, as if a giant beast was roaring.

At this moment, a dazzling golden light suddenly bloomed in the furnace, and a large nine and ten small clusters of brilliant golden light flew out from the furnace, which were ten white pills the size of a dragon's eye, exuding a golden glow.

Flame-like golden rays of light bloomed from the elixir, condensing into a circle of golden light waves, rippling towards the surroundings.

The law dao pattern that appeared on the surface of the pill represented the grade of the dao pill, and it exuded an incomparably mysterious spatial law fluctuation, almost like the dao.

At this moment, under the World Tree, the originally clear sky suddenly surged, and countless smallpox emerged, quickly forming a huge golden cloud, tumbling endlessly.

The vast law fluctuations emanated from the ceiling, and one by one the ceiling fell, submerging into the ten Dao Pills, and the golden Dao Patterns on the Dao Pills became brighter and brighter!

And the Chaos Flood Furnace and the World Tree also shot out a golden light together, submerging into the largest Dao Pill!

After a while, ten pills slowly fell from the sky, and the largest of them was shining with nine golden lines, faintly ten golden lines were generated, and the remaining nine had three golden lines!

The Ten Pattern Dao Dan, also known as the Innate Dao Dan, can be refined by non-human beings, but the Chaos Flood Furnace has an ability called Qiankun Creation, which can create all things, restore the source, and the acquired anti-congenital!
