Knowing the information on the last jade slip, Lin Han was very sure that the Flood Desolation World Refining Furnace could not have been created by the Flood Desolation Old Man, because combining the information on the two jade slips, he knew that the Flood Desolation Old Man had only cultivated the World Refining Furnace to the level of a top-grade royal Dao divine soldier.

And his desolate body has only only cultivated to the realm of Xiaocheng.

This last jade slip completely records the detailed steps of building the Flood Desolation Refining World Furnace, but if you want to create this treasure, it is only possible to have several bloodlines against the sky.

And the power of dissolution in the Valley of Death is to screen cultivators who have the bloodline that can refine the Flood Desolation Refining World Furnace.

There are thousands of bloodlines in the world, what kind of bloodline can match the Flood Desolation Furnace, even the old man himself doesn't know, so he left such a test and waited for someone who was destined.

Lin Han was very happy, thanks to his devouring bloodline, otherwise, he would not have been able to come here at all, and he would inevitably die on the way to here like the bones he saw along the way.

However, it is not without conditions to build the Flood Desolation Furnace, the only condition for the old man of the Flood Desolation is that if he wants to create this treasure, he must first make a demon oath, and in his lifetime, help him destroy the body of the Holy Demon Ancient Buddha on the Burial Mountain.

This is the obsession of the old man of the wilderness, and it is also the only condition.

Lin Han weighed it, gritted his teeth in the end, and made a demon oath in front of the body of the old man in the wilderness.

In fact, he had no choice at all, because if he didn't follow the words of the old man of the Flood Desolation and build the Flood Desolation Furnace, then he would have no way to get out of here at all.

The main materials for building the Alchemy Furnace were all prepared, however, the process of building it was not so easy to complete.

According to the message left on the jade slip, as long as the bloodline meets the requirements, then it is not difficult to refine the Flood Desolation Refining World Furnace itself, but the difficult thing is to raise the level of the Supreme Treasure.

The treasure that has just been created needs a large number of spiritual things to devour and refine, the more energy it refines, the higher its level will be, and this is the opportunity to directly improve the level of the refining furnace, only this time, after that, as the refining furnace continues to refine everything in the world, the level will slowly increase, but the speed of improvement will be tens of thousands of times slower than the first time.

Lin Han didn't rush to make a move, he pondered for a long time, thinking about the things on his body that could provide the refining furnace to improve the level.

First of all, it was the massive amount of spirit crystals that he had obtained in three years, which was a huge amount of money, originally Lin Han was going to keep it for cultivating the Hell Fire God Burning Method, but now, he took them all out without hesitation.

The second is the various elixirs in the Lingmu space, after nearly two hundred years, the Lingmu space has completely become a boundless elixir world.

How much elixir there was, it was difficult for Lin Han to estimate it himself.

With just these two things, Lin Han has a great advantage over ordinary people, in addition to the Supreme Treasure Divine Soldiers, as well as a large number of corpses of strong people.

Now in Lin Han's hands, he has just obtained two ninth-level bloodline treasures, Wuluo Qingyu Yarn and Extreme Ice Streamer Cover, and when necessary, these two treasures can be completely discarded.

In addition to these, he also had dozens of Demon God Cores on his body, as well as the few Star Stones that were left.

"Almost!" Lin Han nodded with satisfaction, and with confidence in his heart, he began to forge the Flood Desolation Refining World Furnace according to the method on the jade slip.

Half a year later, a loud noise suddenly came from the Valley of Death, which alarmed the outer areas of the entire Battlefield of Gods and Demons, and a coercion full of ancient aura rushed straight into the sky, and in the thousands of miles centered on the Valley of Death, all the vitality gathered crazily.

The momentum caused this time was far above Lin Han's breakthrough Tianzun, and those vitality were like a long whale absorbing water, converging into a half-human-high copper furnace in front of Lin Han.

"It's done!" Lin Han was overjoyed.

"I didn't expect this treasure to be born, it actually caused such a big movement, this time, I'm afraid it will attract a large number of people again!" Lin Han thought to himself.

It took half a year for him to finally build the Flood Desolation Refining Furnace, but this was only the prototype of the Refining World Furnace, and the level had only reached the level of the Inferior Bloodline Treasure.

However, as a large amount of Heaven and Earth Yuan Qi was refined by it, this supreme treasure was rapidly ascending at a speed visible to the naked eye.

Half a day later, the Flood Desolation World Refining Furnace was upgraded to the middle grade, and after another day, the level broke through to the top grade.

In this way, half a month later, almost all of the Heaven and Earth Yuan Qi in a radius of thousands of miles was refined into the World Refining Furnace, and the level of the World Refining Furnace had also reached the level of a sixth-level half-step royal Dao divine soldier.

"Not enough, far from enough!" Lin Han shook his head, waved his hand, and threw all the hundreds of billions of spirit crystals in his hand into the refining furnace.

With the addition of these spirit crystals, the speed of the refining furnace increased rapidly.

Three days later, hundreds of billions of spirit crystals were exhausted, and the level of the World Refining Furnace had reached level eight.

Lin Han was greatly satisfied, waved his hand again, and the endless elixir was sent into the furnace by him.

Three months later, Lin Han frowned and stopped, now, the refining furnace has reached the peak of the ninth level, and there are still many elixirs, but Lin Han found that no matter how many elixirs he puts in, although the refining furnace is still refining, it will not help to improve its level.

Lin Han immediately realized that the vast majority of the elixirs in the Spirit Wood Space were of the Saint Rank, and they were obviously unable to meet the level of the Refining Furnace.

After hesitating for a moment, Lin Han threw the two ninth-level bloodline supreme treasures Wuluo Qingyu Yarn and Extreme Ice Streamer Mask in his hand, and at the same time put all the Demon God Cores and Star Stones into it.

In addition, there are hundreds of corpses of strong people, most of these corpses are strong people he killed on the way to the demon capital, originally Lin Han planned to use these corpses to summon phantom beasts after the six origins were unsealed, so these hundred corpses, the worst in life also had the strength of a fifth-level half-step king.

The addition of two ninth-level supreme treasures and the corpses of so many powerhouses caused the aura of the Dehong Desolate World Refining Furnace to skyrocket again, but until all the energy was hidden in the furnace, it still did not break through the level of the Royal Dao Divine Weapon.

"Oops!" Lin Han's heart tightened, and he miscalculated in the secret way!

He didn't expect that it would be so difficult for the Supreme Treasure to break through the Royal Dao Divine Weapon, and seeing that the aura of the Flood Desolation World Refining Furnace had stabilized, Lin Han was anxious.

He knew that once the aura of the refining furnace was completely stabilized, this once-in-a-lifetime opportunity would no longer exist, Lin Han looked at the giant copper furnace behind the old man of the Hong Desolation, and suddenly his heart moved, and he stretched out his hand towards the copper furnace from afar, and performed the fusion technique.

He wants to extract the essence of the bloodline treasure of the old man of the Flood Desolation and integrate it into his refining furnace!

This kind of idea is really a bit crazy, however, it has to be said that this is the only way for Lin Han to raise the refining furnace to the level of the royal path divine soldier at present.

With all his strength in the fusion technique, Lin Han extracted a wisp of pure energy essence with difficulty.

"Is it really possible?" Lin Han was overjoyed and immediately sent this group of Supreme Treasure Essence into the refining furnace.

The bloodline treasure of the old man of the flood wilderness is a high-grade royal road divine weapon, even if the fusion weapon technique is against the sky, it can only extract one-ten-thousandth of the essence of the treasure once when he uses it with all his might.

Even so, Lin Han was greatly satisfied, which meant that he could continuously deliver energy to the refining furnace.

Lin Han opened the Blood Sea Netherworld, and in an instant, his essence blood recovery speed more than doubled, and at the same time, he took out various elixirs that could restore the power of his bloodline and swallowed it.

A supreme treasure essence, the refining furnace takes several hours to completely refine, which also gives Lin Han a chance to breathe, otherwise, with his current strength, even with the assistance of the Blood Sea Netherworld and a large number of elixirs, he can only continuously perform more than a hundred fusion techniques at most.

A month later, the speed at which the refining furnace was refining the essence of the Treasure was getting faster and faster, and Lin Han was already a little unable to keep up with the rhythm, and the refining furnace had devoured so many Essence of the Treasure, and the aura was already infinitely close to the level of the Divine Soldier of the Royal Dao.

Another month passed, Lin Han sat cross-legged on the ground with a pale face, and frequently used the magic power of military fusion for more than two months, and by now, he had completely exhausted the essence and blood in his body, and the power of his bloodline was gone.

Just now, he sent the last wisp of the Supreme Treasure Essence to the Refining Furnace, and whether he succeeded or not, he could only resign himself to fate.

When Lin Han was thinking like this, suddenly, an ancient and majestic aura rose from the refining furnace, and Lin Han's colorless face suddenly showed a look of surprise.

"It worked!" Lin Han was excited, the refining furnace was his bloodline treasure, and it was connected to his heart, so the moment the refining furnace broke through, he sensed it.

"Finally have a royal weapon of your own!" Lin Han showed an excited expression.

It would take a moment for the refining furnace to stabilize its breath, so Lin Han had no choice but to hold back his excitement and wait with peace of mind.

This refining furnace is actually an auxiliary bloodline treasure, in addition to assisting Lin Han to continuously improve the strength of his physical body, cultivate into a desolate body, and reach the royal path divine soldier, it also has an additional attribute, that is, by refining the heaven and earth vitality, or something with spirituality, the recovery speed of Lin Han's essence blood can be greatly improved.

Ever since he had the second realm, the Blood Sea Netherworld, Lin Han's speed of recovering his essence and blood was already much faster than that of ordinary people, and if he added the refining furnace, it would be terrifying just thinking about it.

Choosing to build the World Refining Furnace as his bloodline treasure, although it only had auxiliary effects, Lin Han didn't feel that there was anything wrong.

The World Refining Furnace was completely integrated with his Devouring Bloodline, and in this way, it naturally avoided the biggest drawback of the Bloodline Treasure, and it was impossible for anyone to take it away!

What's more, Lin Han's strongest method now is melee combat, and the body of the desolation is an ability that is very suitable for him.

The aura of the World Refining Furnace finally stabilized, and with a wave of Lin Han's hand, the Flood Desolate World Refining Furnace turned into a streamer of light and drilled into his body.

Lin Han looked at himself and saw that the Refining World Furnace was just perched directly below the Devouring Bloodline, and the black hole formed by Devouring the Bloodline was always rotating at the mouth of the Refining Furnace.

By absorbing the thin heaven and earth vitality in the refining air, the power of the wisps of blood gathered in his body, Lin Han's heart moved, and he took the initiative to absorb a large amount of blood in the sea of blood, this time, Lin Han suddenly changed color, a few minutes later, Lin Han's face was no longer a trace of pale, and the majestic essence blood in his body had all recovered as before.

"Haha......" Lin Han was stunned for a long time about the changes that had occurred in himself, and then he immediately burst out laughing.

"The refining furnace combined with the Blood Sea Netherworld has such a miraculous effect, combined with the blood rebirth supernatural power, from now on, the world is so big, no one will want to kill me!" In the long whistle, Lin Han's strong self-confidence was revealed.
