What Lei Luo didn't expect was that the sword killing relics this time were completely different from before.

At this moment, he was standing on a floating island, and this floating island was the Medicine Heart Island of the Sword Killing Ruins.

For some reason, after he teleported into this place, he came to Medicine Heart Island, but the place where this Medicine Heart Island was located was not the Sword Killing Ruins, and there were no other two islands next to it.

Around this huge floating island, there is a desert-like area, and there is a canopy above me who knows how high.

If it weren't for the fact that he had stepped on Yaoxin Island, he would have suspected that he had come to the wrong place and returned to the outside of the sandbar city in Nanhongzhou, which was a suspended desert oasis.

Looking at the endless desert area below, he hurriedly called out Lu Linglong, and then asked this woman to go to the neighborhood to investigate one or two, while he looked for clues in Yaoxin Island.

Medicine Heart Island has always been a place to grow elixirs, but there is not a single elixir field on this island, only a desolate, dry land, and a large hall in the center.

The three big characters of "Medicine Heart Palace" are still on the main hall, which shows that this place is really the remains of the sword killing.

And he also saw that under the island of Yaoxin Island, there were countless stones piled up in the desert, faintly looking like a magic circle, but those stones were just ordinary stones.

Lei Luo flew around the floating island, and did not find any clues, although the surrounding space is desert and desolate, but the vitality of heaven and earth is very strong.

But when he looked closely at the desert, he found that under the endless sand, there were countless corpses piled up.

Lei Luo's mind turned a few times, and he guessed whether there was a big war here, which is why it caused such desolation, but what was the purpose of the other party's war.

After he couldn't figure it out, he didn't plan to think about it, but glanced back at the direction where Lu Linglong left, and then walked into the Medicine Heart Palace.

Next, he was going to retreat and refine the Humane Five Elements Pill, and this refining might take a long time.

The vitality of heaven and earth here is quite strong, and there is no one to disturb around, so it is a good place to alchemy.

A few days later, Lu Linglong returned to Yaoxin Island and told Lei Luo a bad news.

This place seems to be an ancient battlefield, and under this desert land, there are countless bones of buried people, and even a few places in the desert where death qi erupts, forming a dangerous place.

After hearing this, Lei Luo felt that he could let Lu Xiao come out for a move or two, but he didn't know if the other party had digested the treasures he had bought before, and he still didn't choose to call her.

After he learned about this, he asked Lu Linglong to check the prohibition on Yaoxin Island, and he started the great cause of alchemy.

A few days later, Lei Luo calmed down and took out all the five jade boxes kept in the storage bag.

Among these five jade boxes, there are ten level peak demon pills containing five different attributes, which correspond to the power of the five elements of gold, wood, water, fire, and earth, and are the main medicinal materials for refining the humane five elements pills.

The metal demon pill is obtained from the overlord of the three islands overseas, the golden dragon king, the wood attribute demon pill is obtained from the ruler of the Holy Heavenly Emperor's Wood King Domain, the water attribute demon pill is obtained from the master of the East China Sea demon clan, Kun King, and the fire attribute and earth attribute demon pills are all from the Ten Thousand Demon Valley, respectively from the Flame True Man and the Earth Bear King.

Then he took out three acquired things, which were the primers for refining the Five Elements of Humanity, guiding the medicinal properties and divinity in the innate things, so they were indispensable for refining.

The Acquired Essence Yuan Essence Stone was also obtained from the Valley of Ten Thousand Demons, but it was snatched from the barbarians by the Earth Bear King.

The acquired qi came from the Tiansha Sect, and the two generations of great elders of the Tiansha Sect plotted against him, calculated their own plans, and finally all fell into his hands, and this Yuan Qi Stone naturally made him laugh.

The Yuan Shen Stone of the Acquired God was obtained from the Western Barbarian Domain next to the Nanjue Kingdom, and the Yuan Shen Crystals were obtained from the Li family, and then refined, and Lei Luo easily destroyed the Li Grand Master and slaughtered the entire Li family.

In the end, he took out three more innate objects, and three divine objects that shimmered with golden light and were surrounded by vast coercion appeared in front of him.

The innate essence was also obtained from the Valley of Ten Thousand Demons, which was obtained from within the Heavenly Demon Emperor Dynasty back then, and of course the process of obtaining this thing was more dangerous.

He easily slaughtered more than half of the great demons in the Valley of Ten Thousand Demons, and also slaughtered all the high-level leaders sent by the Yellow Sand Sect, the Black Wind Sect and the Imperial Spirit Sect.

The innate qi came from the underground dragon vein of the Imperial City of the Holy Heavenly Emperor Dynasty, and this time he didn't make a move, but stole it, and it didn't cause any turmoil.

The innate god was obtained from the inheritor of the Xuanyin Sect back then, the Huangquan Ghost Mother, and he also slaughtered the entire Huangquan Gate and sent those ghosts to the real Netherworld.

Although the process of retrieving the treasure is very dangerous, it is all worth it, and now it is time for alchemy.

Lei Luo carefully checked the Dan Fangzai of the Humane Five Elements Pill several times, and after confirming that there was no mistake in a word, he sacrificed the Danwang Ding, and then put the three acquired things into the medicine Ding first.

He opened his mouth and spat out, and a milky white baby fire flew out of his body again, and then flew into the medicine pod.

Soon, Lei Luo took out the five demon pills in turn, and then put the wood attribute demon pill into it first, and then the fire attribute demon pill, which was placed according to the rules of formless coexistence.

Wood gives birth to fire, fire gives birth to earth, earth gives birth to gold, gold gives birth to water, and water produces wood, and the five pills gradually turn into five kinds of medicinal liquids with different attributes, and they are intertwined and fused together.

But at this moment, a mutation suddenly occurred.

When the five demon pills with different attributes dissolved, there was a trace of rejection when they fused with each other, and then the five medicinal liquids all boiled in an instant, and finally a scorched smell came from the Dan furnace.

"Sure enough, these five different materials of demon pills require meticulous control to keep them from repelling, no wonder it takes a god-transforming stage monk to be able to refine it, and this operation is not something that a Yuan Infant stage monk can do!" Lei Luo had already predicted.

He didn't have the slightest worry about the loss of the only alchemy material, but calmly sacrificed his natal magic weapon Heavenly Dao Wheel.

When the Heavenly Dao Wheel was able to restore the innate god, he knew that he only needed time, and this elixir would definitely be successfully refined.

Because the Heavenly Dao Wheel can restore the innate divine objects, then it must also be able to recover the medicinal residue that has been refined by itself.

Sure enough, in a layer of golden light, the residue of the five pills mixed together was slowly separated, and gradually returned to the original appearance of the demon pill.

It's just that after more than a dozen breaths, the Dao pattern dissipates into nothingness, and the golden light in the Dan furnace is extinguished, and there are five demon pills of different colors lying in the furnace again.

Seeing this situation, Lei Luo breathed a sigh of relief, and then began to think about the gains and losses just now, and his body sat quietly and waited.

Because there is no way to continue refining today, I can only wait for the recovery of the Dao pattern tomorrow.

The next day, the alchemy began again.

This time, compared with yesterday, the process of alchemy took a few breaths more, but in the process of mixing the power of the five elements, a trace of flaw appeared again, and finally fell short.

Wrapped in golden light, the five demon pills returned to their pre-refining state, and Lei Luo meditated again, beginning to think about which step had gone wrong just now.

In the blink of an eye, a month has passed.

Outside Yaoxin Island, Lu Linglong took Lu Xiaozheng to fly away in this boundless desert, and their goal was the place where the dead qi broke out here.

The corpses here have formed corpse transformations, and there are even many Yuan Infant Stage refining corpses with not low strength, and in this dangerous place, these refining corpses are all in groups.

Even if Lu Xiao made a move, it would take a quarter of an hour to fight with these refining corpse groups before he could clean them up.

And Lu Linglong couldn't make a move, because the corpse refining was not affected by the ghost qi, and the illusionary powers of the ghost things were also ineffective for these dead things that had no senses and acted on instinct.

However, Lu Xiao ate a lot, and devoured these strange-looking refining corpses, including both humanoid and unknown monsters, and some tall and abnormal demons with dark bodies.

Especially when he saw those demons, a trace of surprise flashed in Lu Linglong's eyes, obviously sensing some clues here.

"Here, could it be the ruins of the ancient demon clan in the legendary Minan Prefecture, but isn't this the ruins of the Sword Killing Sect, how can this be, is it the handiwork of the Venerable Master Chen Lin again?" the woman guessed.

Inside the Medicine Heart Island.

In front of Lei Luo, the Danwang Ding flew up in the air, and the flames in the medicine tripod soared into the sky, and the five-colored medicinal liquid intertwined in the air, and faintly formed a multicolored ring.

"After a month, I finally completed the fusion of the power of the five elements, and the next thing is the order in which the three divine objects are placed one after another, which is another troublesome matter!"

He took out three artifacts from his storage bag, and then chose the Innate Essence first.

Looking at the golden artifact in his hand, he sighed, because this fusion must have taken a long time.

The Innate Spirit flew into the Danwang Ding under his control, but soon there was a rejection reaction, and a violent explosion was heard.

"Bang" The medicine pod smashed to the ground, the liquid of the power of the five elements spilled to the ground, and the innate essence also shattered into countless golden fragments.

As if he knew that this would be the case, Lei Luo summoned with one hand, and the Heavenly Dao Wheel slowly flew out, and the golden Dao pattern flew towards the vicinity of the Danwang Ding in the distance under his control.

Soon, the golden light disappeared, and the innate essence in his hands, the Five Elements Pill, and the Danwang Ding all recovered as before.

"Go on!" a resolute shout sounded, and the alchemy continued.

Five months later, inside the island of Yaoxin.

Lei Luo slowly looked at the Danwang Ding spinning in front of him, and the five different attributes of the medicinal liquid in the Danwang Ding had gradually fused and formed a colorless ring.

And in the ring, the golden liquid flows, which is precisely the reason why the innate essence, the innate qi and the innate god have reached a delicate balance.

After more than a hundred refining in five months, after day and night reflection, and repeated verification, he finally came to this point, completely fusing the power of the five elements and the three innate divine objects.

However, this is only the first big step in alchemy, because these medicinal powers have not yet hit together, and they have only reached a delicate balance.

Lei Luo controlled the Danwang Ding, as well as the infant fire in his body, so that the power of the five elements fused with the three innate divine objects slowly flew into the Ding, and then wrapped this thing and began the next step of refining.

Half a year later, Lu Linglong returned to Yaoxin Island and told Lei Luo that there were traces of monks nearby.

Lei Luo, who was concentrating on alchemy, naturally couldn't be distracted by the monks who appeared around him, so he could only let this woman watch it.

Lu Linglong took the little white fox and Lu Xiao together to arrange a very high-grade phantom array outside the Medicine Heart Island, and did not skimp on materials, and arranged many defensive magic arrays one after another to ensure that the Medicine Heart Island would not be disturbed by others.

Another half a year passed, during which one after another monks discovered the phantom array near Yaoxin Island, and some of them were so strong that they actually discovered the island in the phantom array.

But after a few attempts, none of them broke through the phantom array and the defensive array, and finally had to leave this place and go elsewhere to find opportunities or treasures.

And in the Medicine Heart Island, Lei Luo finally came to a critical step for Cheng Dan.

It took more than a year before and after, and he finally completely fused the power of the five elements, and the prototype of the elixir had been formed.

At this moment, within the Danwang Ding, there were three fluorescent and flickering multicolored pills emitting a golden light, as if they could echo with the surrounding heaven and earth vitality.

And after the elixir appeared, a spiritual energy vortex was rapidly forming in the sky, and countless spiritual powers around it were converging towards this place, which was actually Cheng Dan's celestial phenomenon.
