Mortal blood!

Lin Fan was shocked.

If the natal sword magic weapon he had worked so hard to refine was just a blank, it would not be of any help to him.

Only refining a truly powerful natal magic weapon was Lin Fan's ultimate goal.

"Hmm?"

Lin Fan raised his eyebrows, his expression was extremely solemn.

Seeing that Lin Fan was on the verge of exploding with anger at this moment, Shuhun naturally did not dare to be negligent.

"Master, ordinary cultivators refine their own natal magic weapons by just hammering the refining materials step by step, and then cultivating them in the dantian. This method is very time-consuming and cannot be done without great perseverance."

"I do know a formation that can allow you, the master, to cultivate a real spiritual magic weapon in the shortest time!"

Shuhun hurriedly explained with a smile.

Lin Fan thought carefully for a while and finally understood what Shuhun meant.

"Ordinary life magic weapons are like scrap metal before spiritual communication. Their power is only slightly stronger than that of ordinary spiritual tools. Only those truly powerful spiritual magic weapons are the most terrifying existence!"

"I spent more than ten years to comprehend the "Xuanhuang Refining Technique" and collect top materials for refining the Five Elements Sword. Isn't it just for the purpose of cultivating spiritual magic weapons? If it weren't for the timely reminder of the book soul, I'm afraid I would have to follow the old path of cultivating magic weapons like others!"

Thinking of this, Lin Fan looked at the book soul curiously again.

"I didn't expect you to be of some use. If so, why don't you tell me the spiritual formation you know?" Lin Fan said.

Seeing the expression on Lin Fan's face, it finally relaxed a little.

The pressure on the book soul was also reduced a lot at this moment.

"Yes, master!"

The book soul agreed and then told the story.

"The spiritual formation I'm talking about originated from the True Immortal Realm. It was created by a famous sword cultivator. I can't remember who created it. However, I remember the method very clearly."

"Master, before you refine your life magic weapon, you need to blend your essence and blood into the purified refining materials. Then, outline a simple spiritual formation. Repeat this three times to succeed."

"The magic weapon refined by this method is naturally connected to your mind. After careful training, it will be even more powerful!"

Lin Fan looked ecstatic.

"Leave the matter of purifying the refining materials to the mysterious copper bottle. Although it takes time, it is worth it."

"In this way, as the quality of the materials improves, my success rate in refining my life magic weapon with the "Xuanhuang Refining Technique" will also be greatly increased."

"As for blending your own essence and blood into the refining materials, it is much simpler!"

After thinking carefully for a while, Lin Fan suddenly realized that the refining method mentioned by Shuhun, although it seemed not difficult for him.

But for other immortal cultivators, it is as difficult as ascending to heaven.

First of all, the purification of refining materials is a long-standing problem.

Not only does it take a lot of time, but it is also very easy to go wrong.

It is even very common to spend decades purifying refining materials and get nothing.

Thinking of this, Lin Fan confirmed the matter of the spiritual formation with Shuhun again, and only after he had thoroughly figured it out, he sealed Shuhun in "Shuhun's Self-cultivation".

And he himself began to purify the refining materials.

Wow!

Lin Fan flipped his palm, and all the refining materials he collected were completely presented in front of him.

Sanyang Xuantie for refining gold-attributed natal magic weapons, Wannian Lightning Struck Wood for refining wood-attributed natal magic weapons, Xuanbing Heavy Water for refining water-attributed natal magic weapons, and Wanzai Chenni for refining earth-attributed natal magic weapons.

Each of these things is the top material among refining materials.

Even so, Lin Fan also planned to use the mysterious copper bottle to strengthen and purify these things first.

"Refining the life magic weapon is no small matter. I must always stay in peak condition. So, in the next period of time, I'd better go to the refining room for retreat!" Lin Fan said.

While speaking, Lin Fan's mind moved, summoned Mu Yan and gave her some instructions, and then went directly into the refining secret room.

Buzz!

As the array light curtain in the refining secret room was completely closed.

Lin Fan immediately calmed down and took out the mysterious copper bottle.

Then, he took out a lot of low-level talismans and kept putting them into the mysterious copper bottle for strengthening.

Only when the super strengthening was about to start, Lin Fan put the three-yang black iron into the mysterious copper bottle.

Boom!

A powerful spiritual light gushed out.

In an instant, a white light column dozens of feet high appeared in the air.

On the surface of the copper bottle, the complicated scratches quickly connected together, forming a emerald green entangled flower.

At the same time, the mini dragon soared up from the mysterious copper bottle, and when it appeared at the top of the light column, it opened its mouth.

All the spiritual energy of the heaven and earth nearby was sucked out by the mini dragon in the blink of an eye, and then sent into the mysterious copper bottle.

At this moment, Lin Fan was surprised to find that the Sanyang Black Iron in the mysterious copper bottle had become extremely transparent.

The red light continued to bloom from the mysterious copper bottle, and the impurities inside were also squeezed out little by little at this moment.

In just a few breaths, the quality of the Sanyang Black Iron was improved at a speed visible to the naked eye.

"It is worthy of being super-enhanced, even the quality of the Sanyang Black Iron has improved a lot. If so, I should be able to use it to refine the gold-attributed life magic weapon with excellent results!" Lin Fan said happily.

Next, Lin Fan spent another half a month patiently super-strengthening all the materials with the mysterious copper bottle. Then, according to the book soul, he dripped his own blood into each refining material and carved the spiritual array.

This was repeated three times. After everything was ready, Lin Fan confirmed again and again that there was no problem with the spiritual array he carved. Then he began to refine the Five Elements Sword.

"The Five Elements Sword has different properties, but it is a whole. Therefore, each natal sword with different properties seems to be independent, but it needs to be refined at the same time."

"This requires a very high level of refining. Especially when the five attributes of the natal magic weapon need to be refined at the same time, it is even more necessary to concentrate on five things."

"If it weren't for this period of time, I strictly practiced refining according to the requirements of "Xuanhuang Refining Technique", I'm afraid I wouldn't dare to try to refine the Five Elements Sword."

Lin Fan muttered and took out all the reinforced refining materials.

The next moment, he casually made a move, and a refining cauldron about ten feet in size was immediately placed on the mouth of the ground fire.

Boom!

In an instant, a fire dragon several feet thick rushed out of the ground fire and kept licking the refining cauldron.

The red flames emitted a terrifying temperature. In just a few breaths, the temperature in the refining cauldron reached the level of refining.

"The temperature is almost right, it's time to refine."

Lin Fan did not hesitate and quickly threw five refining materials of different properties into the refining cauldron at the same time.

Whoosh!

A stream of hot water vapor rose from the refining cauldron.

Xuanbing heavy water was refined at the first time.

The volume was obviously reduced, but it seemed more refined than other materials. Lin Fan looked happy, and used his mind to pull the Xuanbing heavy water to the lower temperature in the refining cauldron to continue refining.

However, the Sanyang Xuantie, which required a higher temperature, was placed by Lin Fan in the center of the refining cauldron with the highest temperature.

At this moment, Lin Fan's attention was highly focused.

His clear eyes and divine thoughts had been pushed to the extreme by him.

He could easily detect any slight movement in the refining cauldron.

However, at this moment, Lin Fan did not dare to be careless at all. He patiently paid attention to the changes in the ground fire and controlled the fire temperature at any time.

In a flash, a full six months had passed.

In the refining chamber where Lin Fan was, there was a sudden sound of metal collision.

Not long after, five kinds of dazzling light rushed out of the refining chamber and fell on the protective formation of the refining chamber, causing the protective formation to shake violently.

Lin Fan, who was controlling the refining cauldron, could not help but look ecstatic.

"Five-color spiritual light suddenly appeared. Has my Five Elements Sword, my life-long magic weapon, finally been refined?"
