Juelong Stream is a place name in the forbidden land. This place name is marked by the four major families, however, the four major families are only marked with a name, and nothing else. However, the Absolute Dragon Stream itself is a place with a vast area that is almost equal to a tenth of the Broken Cang Mountain Range.

The place where Wang Yilong found the flying sword was in the central area of the Juelong Stream, a place that even the four major families had never visited. Lin Feng hugged the little girl, and after a day and a night of rapid travel, he finally came to the place where Wang Yilong found the flying sword.

The flying sword is in a cave in a hidden mountain stream, and there are Dan furnaces for alchemy, Ding furnaces for refining, and all kinds of rare heavenly and earthly treasures, but these heavenly and earthly treasures have completely lost their essence of heaven and earth because of too much time, and they have turned into nothingness when they touch it.

The Dan furnace used for alchemy and the Ding furnace used for refining are also quite corroded, obviously, it has lost any value of alchemy and refining. Probably, the only treasure here is the flying sword found by Wang Yilong.

Speaking from the heart, the flying sword that Wang Yilong found can only be said to be a low-grade flying sword, and it requires the cultivator to inject internal strength into it before it can fly with the cultivator. A truly top-grade or top-grade flying sword does not require a cultivator to inject internal strength at all. Thousands of miles away, in an instant. There are also a variety of super features. For example, it has its own flame, as long as the owner's internal strength is injected into it, the flame can explode three feet to hurt people.

Wang Yilong's flying sword, among the flying swords, is really not a good thing. However, no matter how bad it is, it is still a flying sword. For the Shushan Sect, where the method of refining the flying sword has been lost, any flying sword has a very extraordinary significance. Of course, for the four major sects, it doesn't matter whether this flying sword can fly or not, the important thing is that any flying sword has an extremely rare metal: Jiuyang Flame Copper.

Legend has it that in ancient times, a genius disciple of Shushan painstakingly refined weapons in order to be able to fly with a sword. He wanted to forge a sword that could fly with him. He had spent nearly a thousand years trying all kinds of known metals, but there was no way to make the flying sword fly. Later, in a forbidden place, he stumbled upon an ancient scroll, which said that the light of the nine suns was used to shine on the bronze, and when the bronze was burned in the flames, only the copper essence remained, and the refining vessel was taken to great effect.

Although he didn't know what the 'miracle' was, he decided to get his hands on it. But in the sky, there is only one sun, and it is impossible to have nine suns. This Shushan disciple thought that the so-called nine suns should be so that the bronze is exposed to the same heat as the nine suns for a certain period of time. To this end, he invented a magical formation that could turn bronze into Nine Sun Flame Copper at extremely high temperatures.

When he made the first flying sword out of Jiuyang Flame Copper and took him to soar into the sky, the flying sword officially became the lifelong pursuit of every Shushan disciple.

Later, after the improvement of the successive masters of the Shushan faction, the flying sword is no longer only able to lead people to fly. It also has many other benefits. In order to give greater play to the role of flying swords, the ancestors of Shushan invented the sword trick. Every Shushan disciple who practices the Imperial Sword Technique will exchange his life for a flying sword, and this flying sword has either just been refined or has been successfully refined. In short, the only function of the Imperial Sword Technique is to let the Shushan disciples find the flying sword that belongs to him.

Originally, Shushan himself would refine the flying sword, and it was very easy to let the disciples find the flying sword, just let the disciples enter the 'sword hall', and which flying sword made a light groan, then which flying sword belonged to the disciples of Shushan. Moreover, once this disciple dies, the flying sword will lose its effect, and from now on, he will not recognize the Lord again. Of course, there are people with super strength who can change the life of the flying sword, but even if it is changed, the ability of this flying sword is only one percent of the original flying sword. Therefore, no one, especially the people of the Shushan faction, was willing to change the fate of the flying sword.

However, in the battle of the ancient gods and demons, the Shushan faction was almost wiped out, countless masters fell, and the Shushan faction also changed from the first major sect in the cultivation world to a small sect that was not even a fourth-rate.

Although the heads of the Shushan faction in the past generations have worked hard to restore the sect's former glory. However, the Shushan faction, which has lost almost all the masters above the Immortal Realm and almost all the classics of the sect, is not easy to revitalize.

Fortunately, the Shushan faction still has the flying swords left by the ancestors for the disciples to choose, otherwise the Shushan faction can almost seal itself as a mountain gate. However, the Shushan faction had lost the method of refining the flying sword, and even more so the method of refining the Jiuyang Flame Copper. Therefore, the Shushan faction spread to 5,000 years ago, and it directly closed the mountain gate. Because the Shushan faction no longer has a flying sword for disciples to choose from.

Wang Yilong traveled to countless famous mountains and rivers, in order to see if he could get the opportunity to find a flying sword that had been lost.

He found it in the Absolute Dragon Stream, but he didn't expect it, but it brought him death.

Although the people of the four major families do not know how to use flying swords, the Nine Yang Flame Copper on the flying sword is a superb heavenly and earthly treasure for refining magic weapons. If it weren't for the fact that Shushan sealed the mountain gate five thousand years ago, the world would have no way of knowing the location of the Shushan faction. I am afraid that the people of the four major families would have killed the Shushan faction a long time ago and snatched all the flying swords whose masters were dead from the sword mound.

Therefore, after Wang Yilong came to the Forbidden Land of the Flood Desolation and resonated with the flying sword, he was immediately discovered by the people of the four major families, and the next thing was to snatch it, but the hunting team with heavy losses did not expect that he met Lin Feng halfway.

Lin Feng took a turn in the cave and found that the cave had been turned upside down, and it was obvious that the people of the four major families wanted to look inside to see if there were any good things in it. But the results obtained are not very good. Otherwise, they wouldn't have cut down the corpse sitting in the innermost part of the cave in order to vent their anger.

Lin Feng found a corner and put the little girl who was asleep, and then took out the dry food and ate it. He had to wait for the little girl to wake up, and then go up the mountain to find the 'phantom flowers'. After eating, Zhao Fei went to look at the rusty Dan furnace. After finding the 'Phantom Flower Grass', he also had to find a Dan furnace to refine the 'Heavenly Phantom Pill', if this Dan furnace could still be used, he wouldn't have to go outside to find the Dan Furnace.

The Dan furnace is full of traces of rust, and if you touch it with your hands, you will continue to drop some metal slag, but the main body is not damaged, if there are no other dark wounds, it can be used to refine the 'Heavenly Illusion Pill'. Of course, the premise is to clean up the inside and out first.

While the little girl hadn't woken up yet, Lin Feng began to clean up the Dan furnace. The Dan furnace was too badly corroded, and in some places, when Lin Feng cleaned up all the corroded locations, the original furnace wall that was more than twenty centimeters thick was like a blank piece of paper. Lin Feng doubted whether this thing could be alchemized. But if Zhao Fei didn't want to run outside to find the Dan furnace, then he couldn't give up this thing.

Lin Feng cleaned up all night, and when the day was dark, the little girl woke up from her deep sleep.

"Hug ......"

The first words of the little girl when she woke up made Lin Feng find that the sky was bright.

The little girl pointed to the Dan furnace that had been cleaned up by Lin Feng.

Lin Feng was a little strange, looked at the position of the little girl's point, and couldn't help but be taken aback when he saw it. Because, the position of the little girl's finger was actually cracked, and Lin Feng didn't notice it at night. Through the sunlight, you can see it very clearly.

Lin Feng hurriedly passed, if the bottom cracked, there would be no way for this Dan furnace to be used anymore.

The fact made Lin Feng extremely depressed, not only was the bottom cracked, but there was also a place that was exposed.

Lin Feng slapped the Dan furnace on top of it, and the Dan furnace couldn't bear it, and it turned into a pile of scrap iron and rotten iron. Just when Lin Feng was extremely disappointed, he was stunned to find that among the pile of scrap copper and rotten iron, there was actually a black Dan furnace the size of a sea bowl.

Lin Feng hurriedly took the Dan furnace to the entrance of the cave, and with the help of the sun, Lin Feng was pleasantly surprised.

This Dan furnace is not an ornament, but a real Dan furnace.

A standard Dan furnace is three meters high, and the volume is at least seven or eight cubic meters. Therefore, it is very inconvenient to carry the Dan furnace. Although the weight is nothing for a cultivator, the volume is too large, and even if there is a storage ring, such a large volume is a very big challenge for the space of the storage ring.

Therefore, any alchemist wants to miniaturize the Dan furnace, but if it is miniaturized, there is no way to engrave the alchemy array talismans, various control runes, and various cleaning runes on the Dan furnace. And without these Dan furnaces, there is no way to refine any good pills at all. At the same time, even if it is refined, the rate of Cheng Dan is too much lower.

Therefore, the standard Dan furnace can almost be said to be the smallest Dan furnace with complete functions.

Of course, there are also simplified versions of the Dan Furnace, which have more than doubled in size, but they can only refine some pills that are not used by cultivators. Therefore, among the cultivators, no one will use a simplified version of the Dan furnace.

There is also a palm-sized Dan furnace, which is just an ornament, and it cannot be alchemized.

And this Dan furnace in Lin Feng's hand actually placed a huge number of control runes, cleaning runes, and alchemy array runes together in an almost dreamlike combination, although Lin Feng hadn't tried it, but he had an intuition. Lin Feng knew that this Dan furnace was the best Dan furnace.

In order to verify his thoughts, Lin Feng personally refined a furnace of 'Heavenly Spirit Pill', which Lin Feng had all the heavenly materials and earth treasures needed for the Heavenly Spirit Pill, and he also got the flame essence in the head of the Red Flame Nine-headed Bird, which was the best furnace fire. The excellent Dan Furnace, coupled with Lin Feng's proficient alchemy techniques, this Furnace Heavenly Spirit Pill actually achieved an almost 100% success rate. In other words, there is not a little bit of heaven and earth essence qi in the heavenly and earthly treasures wasted.

In addition to this, this Dan furnace is only the size of a sea bowl, and it doesn't take up much space at all when placed in the storage ring, so it can be said that anytime, anywhere, as long as other conditions allow, Lin Feng can refine the pill.

"Great!"

Lin Feng couldn't help but exclaim excitedly, put away the Dan Furnace and the Pill, and Lin Feng destroyed the Ding Furnace of the refining weapon again. However, a small furnace was not found in the furnace, but a palm-sized square piece of metal. The metal sheet is very thin, and many ancient characters are densely engraved on it. The top few words are: Apocalypse Flying Sword Refining Method.
