"It seems that this stone should be the Heavenly Fire Stone! I didn't expect that I could have such a great opportunity. Yuan Fei glanced at the strange flint for a few moments, and finally whispered with a glint in his eyes.

The celestial flint he spoke of was something he had seen in a classical book.

It is said that this stone is not only extremely hard, but also emits a powerful alien flame on its own, and it is permanently inextinguishable.

And because of the magic of this stone, countless monks are expecting to integrate this stone into their magic weapons, so as to increase the power of the magic weapons, especially those monks with fire attribute spiritual veins are crazy about this stone.

But even in ancient times, the celestial flint was extremely rare, and it was often in an extremely hidden place, and it was even rarer to be found.

However, once a monk really finds this stone and refines the magic weapon, the magic weapon is absolutely amazingly powerful.

In fact, when the Heavenly Fire Stone was submerged into the black dragon's body, Yuan Fei had already noticed it, and immediately thought of this possibility in his heart, so even though he faced great danger in the end, he still resolutely took this stone into his hands.

Speaking of which, the black dragon is really strange, because according to the classics, although this heavenly flint is a rare heavenly treasure, I haven't heard of the rumors of conjuring a fire spirit, not to mention that a real dragon exists!

Of course, none of this is something that Yuan Fei can understand. The most important thing for it now is how to use this celestial flint.

After the thought moved, Yuan Fei's sleeve robe shook, and two jade boxes appeared in front of him, with a piece of gold-colored pebble-shaped ore and a thumb-sized blood-colored ore inside.

These two items were exactly what he had found from a pile of treasures, the 'Essence of Ugin' and the 'Blood Crystal' needed to refine the Fire Devouring True Demon Sword.

When Yuan Fei had just discovered the two materials, he was extremely excited, because as long as he found another spiritual material, he could refine the magic sword for the second time.

But with Yuan Fei's current situation, it is a little too late to look for it.

At most, it will be more than ten years before it will enter the Guangling Realm. And there are many dangers inside, even if the existence of the God Refining Period goes deep into it, it is very likely to fall, not to mention that he is a monk of the Yuan God Period.

Therefore, no matter what the method is, as long as it can increase the means of life preservation in a short period of time, it will be completed as much as possible.

Although so far, the second refining magic sword is still one material short of being collected, but whether it is the material or the degree of cherishment, the Heavenly Fire Stone is much higher. If you want to use this stone instead of the original refining materials, even if you can't reach the point recorded in the secret canon, you won't be far behind.

Anyway, he didn't know when he wanted to advance to refine the gods, and now he had to try his best to save his life first.

As for the remnant soul of the black dragon, Yuan Fei also thought of a way to deal with it. But whether it can be as he thinks can only wait until the second refinement of the real magic sword is successful.

Thinking of this, Yuan Fei slapped his waist with one hand, took out a jade slip, and then put it on his forehead, and looked at it with his eyes closed.

......

Time passed, and ten years passed in a blink of an eye.

In the cave, Yuan Fei sat on the futon with his eyes slightly closed, and his body was motionless, as if he was carved from wood and stone.

Not far from the opposite side, a huge purple Ding furnace had already turned red and purple under the scorching of a black flame, and bursts of "snort" piercing sounds continued to come, making the nearby void illusory and abnormal.

And in the giant ding, there is also a black flame, sometimes strong and sometimes weak, tumbling and surging, and from it there is a strange sound like a dragon roaring and a tiger.

After a while, Yuan Fei's eyes suddenly opened, and at the same time, his hands were separated by a little in the air.

Suddenly, after a burst of black flames in the Ding Furnace, it suddenly rose into the sky, and then condensed in mid-air, turning into a black dragon with a length of feet.

The black dragon looked vicious and abnormal, hovering with fangs and claws, it was very similar to the huge 'black dragon' in the cave back then, but it was much smaller, but the aura it exuded was equally powerful.

Moreover, the scales on the black dragon's body transformed by flames are extremely realistic, and a pair of copper bell-like eyes are flashing, as if they are not small in spirit.

Yuan Fei raised his head and looked at the black dragon floating in mid-air, with a very satisfied expression on his face.

Then he grabbed it with one hand, and the black dragon's body shrank rapidly, and finally turned into a flying sword with black flames on the surface, and appeared in Yuan Fei's hand in a flash.

Since Yuan Fei returned to the secret room, he has been in retreat, studying the refining method of the Fire Devouring True Demon Sword as if he was obsessed.

And the final result not only made him breathe a sigh of relief, but even rejoiced in his original decision.

Speaking of which, the process of refining the magic sword is extremely difficult, and the other materials are not a big problem, but the only thing that is troublesome is the heavenly fire stone.

The Heavenly Fire Stone has been calcined by a different fire for an unknown amount of time, and it is not afraid of ordinary flame incineration, let alone refining it.

Even though the Nine Yuan True Fire is now quite powerful, it is not very impressive in refining this stone. Although Yuan Fei tried various methods, he still had little success.

However, once Yuan Fei inadvertently dripped a drop of essence blood on it, the Heavenly Fire Stone actually began to melt slowly.

This discovery naturally made Yuan Fei overjoyed.

It's just that this method of depleting essence and blood can hurt the monk's vitality, so Yuan Fei only forced out a small amount to help the refining of the Heavenly Fire Stone, and he didn't dare to be sloppy, so he quickly took the pill to recover.

And just refining all the materials, it took almost five years, and then the refining of the real magic weapon began.

In the end, the second refining of the magic sword was finally completed, and even though Yuan Fei changed the original refining materials, the magic sword was not affected at all, but was sharper than before, and the grade reached the level of a high-level magic weapon.

Although it was only a high-end mid-grade, it was enough to make Yuan Fei excited.

You must know that the magic weapons used by ordinary cultivators in the God Refining Period are also above and below the high-level magic weapons, not to mention that the magic sword in their hands is still of medium grade.

Moreover, under the continuous cultivation of Yuan Fei's Yuan Shen in the future, or after his advanced refining of the gods, the power of this magic sword will definitely increase significantly.

In addition, during this period, Yuan Fei also completely refined the remnant soul of the black dragon's head into the Nine Yuan True Fire.

What he didn't expect was that at first he just wanted to increase the power of some true fire, but who knew that after integrating it into the remnant soul of the black dragon, the power of the Nine Yuan True Fire not only increased greatly, but also increased a lot of spiritual intelligence.

If the Nine Yuan True Fire was only a baby before, it was almost equivalent to a two- or three-year-old child at this time, although it was also weak, but there was a huge difference between the two.

Of course, in addition to refining the magic sword and refining the black dragon soul, Yuan Fei did not forget to meditate and cultivate, and further enhance his cultivation, so that he could break through the next realm before the secret realm opened, which was naturally the best

But it backfired, although he had been cultivating diligently and his cultivation was becoming more and more profound, he was always stuck at the peak level of the middle stage, and he was unable to break through for a long time.

In this regard, Yuan Fei only had a slight regret in his heart.

Over the years, his cultivation has been so smooth that he is now in a hurry to achieve quick success. In fact, not being able to advance to the later stage may not be a bad thing, so it is a good opportunity to take advantage of the precipitation over the years, which will also have many benefits for the future.

After figuring it out, Yuan Fei was no longer obsessed with it. In his spare time, he reads some ancient books and secret anecdotes, and studies exercises, secret techniques, and so on.

In addition, not long ago, Jian Fei's daughter brought her good news. The set of silver light soul extinguishing array flags, with the efforts of this woman for many years, was finally repaired.

Moreover, according to what this woman said, she originally expected that with her own strength, she could restore the power of the array flag at most. But he didn't expect that the process of repairing the array flag this time was extremely smooth, and in the end, the array flag was able to exert almost two percent of the power of the original array.

You must know that this array is a super large array that is claimed to be enough to trap and kill the existence of the Tribulation Period, even if it is only less than two percent, it is more than enough to besiege a mid-stage cultivator of God Refining.

It's just that if you want to exert such great power, you must use high-grade spirit stones to stimulate it, otherwise the power will inevitably be greatly weakened.

Yuan Fei was not worried about this, he originally had some high-grade spirit stones, plus the income from the Luo family, it was completely enough.

Therefore, Yuan Fei was overjoyed in his heart, and did not hesitate to hand over a large sum of spirit stones to Jian Fei, and also gave this woman a lot of magic weapons and pills.

She knew in her heart that this woman had spent a lot of energy in order to repair the formation flag over the years, and of course she had to make up for it.

In addition, Yuan Fei handed this woman a special token unique to Jin Jiawei.

As long as the monk holds this token, whoever he is, he can be protected by the Golden Guard, and this is also Huang Jiulong's intention to buy people's hearts.

Generally, monks will have one or two descendants, but most of them are mortals who are not high in cultivation, or do not have spiritual veins at all, if there is such a powerful backer as Huang Jiulong, naturally no one dares to provoke them.

As a golden armor guard, it is not surprising that Yuan Fei has one or two pieces.

And after receiving the token, Jian Fei was dumbfounded. Originally, he just thought that Yuan Fei's strength was extremely strong and he definitely had a great background, but he never thought that the other party was actually the golden armor guard under the waiting seat of the East King.

While this woman was horrified in her heart, she couldn't help but thank her.

It's no wonder that getting this token is equivalent to having the powerful backer of Dongwang Hou, and the Jian family will no longer have to worry about swallowing their anger in the future.

In addition, this woman still has something that she has been thinking about for a long time, and she was about to open her mouth as soon as she looked up, but as soon as she raised her head, Yuan Fei was already nowhere to be found.

Seeing this scene, the woman couldn't help but sigh, stared at the door and stood for a long time before leaving with a disappointed face.

Yuan Fei has been experienced for a long time, so he has naturally guessed this woman's thoughts.

However, now he is too busy to take care of himself, but he has no leisure to pay attention to these children's affections. What's more, he and this woman can only be regarded as confidantes at most, and there is no affection at all.
