Treasure Gathering Immortal Furnace

Although there are many lightning or flames with special abilities in the cultivation world, most of them are difficult to find.

The flame that was born from the third eye of the Three-Eyed Raven was naturally an extremely domineering flame.

"Don't be too happy yet. Although the Netherworld Fire is extremely powerful and specializes in attacking the soul, the Three-Eyed Raven, which has just reached the fifth rank, cannot breed too many," Zi Yuan said.

"It's alright. With more training, it will eventually become inexhaustible in its usefulness," Lu Fan said without any rush. After all, one must eat one bite at a time and walk one step at a time.

He didn't expect the Three-Eyed Raven to be invincible right after it opened its eyes; that would be unrealistic.

"Since they're about to break through, there's no need to feed them anymore. Let them break through slowly in the spirit beast pouch. The ancestor should also take a rest," Lu Fan said slowly.

"At least you still have a conscience. At this rate, my remnant soul won't last long," Zi Yuan complained irritably.

Lu Fan also looked embarrassed. Then he waved his hand, and the Three-Eyed Raven and the Purple Iris were put away.

Now that my cultivation is stable, it's time to refine my natal magic weapon.

Most cultivators need to use a refining furnace to maintain the temperature when refining magical artifacts or their natal magical artifacts.

However, Lu Fan can skip this step, since he has the molten attribute, which has a much higher temperature than ordinary fire attribute.

With the addition of one's own internal fire, it can be easily refined.

"A natal magic weapon is a crucial item that accompanies a cultivator throughout their growth, and it cannot be taken lightly. I need to concentrate fully from now on," Lu Fan thought to himself as he raised his hand and took out the Azure Nether Profound Iron.

"Well then... let's begin!"

Lu Fan made a hand seal with one hand, then slowly opened his mouth and suddenly spat out a mouthful of scorching lava, instantly enveloping the Azure Nether Black Iron.

Under the intensely hot and molten conditions, the Azure Nether Iron gradually heats up, but the process is extremely slow.

Because Azure Nether Iron has a dark attribute, it has inherent high-temperature resistance and extremely high hardness.

The calcination process alone took Lu Fan more than five months. During this time, he consumed a large number of Qi-restoring pills and absorbed a lot of spirit stones in order to maintain the temperature of the lava.

After five months of continuous forging, the entire piece of Azure Dark Iron was completely transformed into a red-hot iron block.

"It should be ready by now," Lu Fan said, seeing that it was about time. He immediately formed hand seals and began to activate the inner fire.

Huff...

As Lu Fan opened his mouth and spat out a large ball of golden flame, it immediately enveloped the Azure Nether Black Iron. The intense heat of the alchemical fire was extremely high, and in just a short while, the black iron, which had been forged for five months, began to melt into molten iron.

Then, it was shaped according to the appearance of the Azure Netherworld Devouring Light Sword recorded in the Five Extremes Yuan Hunting Sword Formation.

Under Lu Fan's control, the molten iron gradually took shape, becoming the form of a sword blank.

"Next is to remove impurities," Lu Fan then raised two fingers and continuously injected spiritual power into the sword embryo.

Gradually, the impurities mixed in with the sword blank were removed one by one.

This is a delicate task that allows for almost no carelessness, because even the slightest impurity inside will affect the strength of the natal magic weapon.

Therefore, during the process of removing impurities, Lu Fan almost pushed his mid-stage Core Formation divine sense to its limit, leaving no stone unturned, not even a speck of dust.

Such intense refining requires a double strain on both spiritual power and divine sense.

If he hadn't taken the Soul Nourishing Pill to raise his spiritual sense to the mid-stage of Core Formation, he probably wouldn't have been able to withstand it.

Five months have passed in the blink of an eye.

After five months of continuous impurity removal, there was almost no dust left in the entire sword blank, turning it into a completely pure sword blank.

At this point, Lu Fan was nearly exhausted. He had used up more than two hundred Qi-restoring pills in the past ten months and absorbed four or five hundred spirit stones.

However, he still couldn't make ends meet. Keep in mind that this was even with his mutated spirit possessing abundant spiritual energy. If it were any other cultivator, they probably wouldn't have been able to refine it without help.

For example, Ye Lingxi was able to refine her natal magic weapon only with the help of Shi Fengtian, a Nascent Soul expert.

"The final step!" Lu Fan took a deep breath, enduring his weakened state, and once again unleashed the pill fire for the final tempering.

Then another two months passed.

The sword embryo, enveloped in the cinnabar fire, began to take shape, becoming a long sword with a slender design and radiating a strong dark light.

Then Lu Fan raised his hand, flicked his finger, and a drop of essence blood containing the origin of his soul instantly disappeared into the Devouring Light Sword.

This also means that the natal magic weapon he personally crafted is deeply bound to his soul, and once the Azure Netherworld Devouring Light Sword is damaged, he himself will suffer a considerable backlash.

"Finally done!" Lu Fan was overjoyed. After a year of hard work, he finally saw the results!

hum!

As the Azure Devouring Light Sword emitted a sword cry, Lu Fan immediately waved his hand, and after circling in mid-air a few times, the sword landed steadily in his hand.

Lu Fan held it in his hands and examined it repeatedly, as if it were a priceless treasure, and the more he looked at it, the more he liked it.

Huff...

With a casual wave of his hand, Lu Fan created a jet-black sword aura, as if a basin of ink had been poured forward.

Boom!

A loud bang rang out, and a sword mark half a meter deep was cleaved in the wall in front!

"The Azure Devouring Light Sword is indeed domineering. With a casual swing, it can create such a powerful slash. If I were to face the golden corpse in the underground palace with my current strength, I would probably be able to cut it into powder with just a few sword strikes." Lu Fan stroked the sword and couldn't help but feel proud.

After all, he now possesses a natal magic weapon, and his strength is vastly different from what it used to be!

Then, Lu Fan raised his hand, and the Azure Netherworld Devouring Light Sword was immediately absorbed into his Qi Sea, circling around the Golden Core.

A natal magic weapon is far superior to an ordinary magic weapon. It moves at will and is continuously nourished by the golden elixir in the dantian, only growing stronger with each passing moment.

Although he had been in seclusion for four years, his cultivation had become stable, and he had even refined his natal magic weapon, Lu Fan was not in a hurry to come out of seclusion.

He plans to continue his seclusion for a few more years, to cultivate the Sword Shadow Splitting Light Technique to the fifth level, and at the same time, to cultivate the True Qi Gong to the third level.

In the following period, Lu Fan practiced the Sword Shadow Splitting Light Technique and the True Qi Technique alternately, without feeling tired. Instead, he was immersed in the pleasure of improving his strength.

In the sixth year of his seclusion, the Sword Shadow Splitting Technique successfully reached the fifth level. At this moment, it can now split into seven or eight hundred sword shadows, covering a terrifyingly large area.

This also allowed him to dedicate time to practicing the True Qi Gong.

Three more springs and winters have passed, and he has been in seclusion for a total of nine years.

Lu Fan also successfully cultivated the True Qi Gong to the third level, a level that had reached the level that Song Zhiyuan had reached back then.

However, Song Zhiyuan was a late-stage Core Formation cultivator, while Lu Fan, although he had reached the third level, was still somewhat inferior to Song Zhiyuan in reality.

He originally planned to continue his seclusion for another year, making it a total of ten years before emerging to go to the Li Huo Cave.

However, his overall strength has now grown to the maximum that the early stage of Core Formation can withstand, and if he wants to continue his seclusion, he must take Core Formation stage pills.

However, Lu Fan doesn't have any Golden Essence Pills for Core Formation stage cultivators right now, so he can only leave seclusion to find the two Supreme Elders to see if he can get a few for free so he can make a batch.
