Before he even entered the room, a strange smell had already entered his nose.

"Senior Brother Lin, I won't accompany you in!" Wang Feng seemed to be prepared, and as soon as he retreated, he was about to exit the big house.

Lin Shan nodded, walked into the room alone, and immediately frowned, the room was very large, but he didn't know how many years it hadn't been tidied up, it was full of all kinds of thick smells, dust, musty smells, and peculiar smells emitted after the decay of the magic weapon, which made it difficult to breathe.

The room is full of all kinds of Dan furnaces, triangular four-legged, large and small, densely piled up, it seems that the Dan furnaces that have been eliminated in Fengling Valley for thousands of years have been piled up here, but it is obvious that no one has been to this Dan furnace room for a long time, these Dan furnaces are covered by thick dust, and they can no longer see the original shape.

The light in the room was dark and damp, Lin Shan was quite disappointed, in such an environment, could there still be a usable Dan furnace left? He really wanted to leave, this is not a waste of time, but after thinking about it, it is safe, the main thing is that there are too few spirit stones in the pocket, if you can find the most barely usable one here, it should be able to afford its price.

On the ground, one by one Dan furnaces are placed horizontally and vertically, many Dan furnaces can be seen to be broken, missing a corner or a hole, Lin Shan held his breath, gently opened these dusty Dan furnaces, and carefully checked them one by one, and the room raised pieces of dust and mist from time to time.

He was speechless, there were several Dan furnaces, as soon as his hand touched it, he actually hit a hole, the age was too old, the furnaces with poor refining materials were rotten, and after a long while, he saw that he was about to finish searching, and he hadn't seen a barely usable Dan furnace.

Lin Shan was basically dead, and there were still a few Dan furnaces piled up in the corner, he cheered up, cleaned them up one by one, and finally found a Dan furnace covered in dust, rust, and brown hard lumps at the bottom, the Dan furnace is not big, it is estimated to be more than two feet high, but now due to dust, hard lumps, etc., it is mixed into a mess, but it is vaguely identified as a Dan furnace according to the shape.

Lin Shan first carefully wiped the dust it indicated, revealing the hard lump inside, and then took out the Huoyun Sword, and carefully scraped off the brown hard lump with the Huoyun Sword in his hand, the hard lump was quite hard, he tossed for a long time, scraped down the ground layer by layer, and was already sweating profusely, and he didn't know how long this Dan furnace had been stored here to accumulate such a thick hard lump.

After these tosses, he finally vaguely saw the shape of this Dan furnace, and charcoal-like black, has scraped off a lot of hard pieces of the furnace body, vaguely visible a lot of patterns, there are landscapes, valleys, and people, etc., in the middle of the furnace, carved a few words, but unfortunately wrapped in hard blocks, it is difficult to see what it is.

In terms of appearance, there is a hole in the furnace lid that can be opened controllably, but this hole is covered by a black lid, and the furnace body is equipped with two big ears, and there are many strange beasts depicted on the ears, and he doesn't know any of them.

There are three transparent mirrors on the furnace body, two of which are mostly covered by hard blocks, and it is not known what kind of material they are made of, through which you can clearly see the situation inside the furnace.

Under a mirror, there are two large holes, each of which is exactly the size of an adult's palm, right opposite the bottom of the furnace, slightly above the bottom of the furnace, and there is a bulge, and there is a small black bowl that can be removed next to it, but for some reason, it is the base, it is equipped with three horns, but it also looks simple and generous.

When the lid of the furnace was opened, the furnace was already stuffed with dust, and there were a lot of hard lumps, Lin Shan carefully removed the dust, because there were still hard lumps, and he could only vaguely see the concave structure of the black bottom of the furnace, and there was a tray composed of many small nets lying flat, except for that, there was nothing else in the furnace.

Lin Shan didn't know what this tray was for, he tried to press the bulge that he found on the stove body below, but it was stuck out here, and he tossed for a long time before he could press it down.

As the bulge was pressed, there was a change, the mesh tray in the furnace stood upright, but it happened to be on the black bowl outside the furnace body, it seemed that the black tray poured the things it held into the bowl, and the bottom of the furnace concave actually popped out a small distance, it seemed to be to facilitate the alchemist to take out the bottom of the furnace, seeing this, Lin Shan was secretly frightened, what a delicate design.

He closed the lid of the furnace and flicked it lightly with his fingers, but he didn't hear the sound of the metal, and picked up the furnace again, and found that it was not as heavy as he imagined, but it was a little heavier than ordinary fine iron, and it seemed that it should still be relatively strong and durable.

He carefully checked it again, except for the place covered by the hard lump, everything else was naked, so he walked out of the room with the black Dan furnace in his arms.

Senior Brother Zhao had been waiting for a long time, walking around, and seeing Lin Shan coming out with something, his eyes lit up, he just simply looked at the Dan furnace in Lin Shan's hand, and said: "Senior Brother Lin, here are all items left over from the early years of the sect, because of the age, so there are often problems, let me tell you first, once the delivery is completed, if there is a problem, you can't go back!"

When Lin Shan heard this, his heart beat fiercely, and he felt a little uneasy in his heart, it seems that there are often problems with all kinds of stocks here, no wonder no one has come for a long time, the dust is all over the ground, and the smell is smoky, if it weren't for the monk's body being different from ordinary people, it is estimated that he would have been smoked inside.

Although there was a little uneasiness in his heart, Lin Shan finally gritted his teeth and nodded, Senior Brother Zhao was silent for a moment, and said as if he was a little painful: "Then I will accept you thirty low-level spirit stones." ”

Lin Shan was very happy when he heard this, and directly took out thirty low-grade spirit stones from the aura bag and handed them to him, but the corner of his eye found that the moment Senior Brother Zhao took the spirit stone, the corner of his mouth actually showed a smile of joy, which made Lin Shan's heart feel a pimple, could it be that he was cheated by this old man?

"Senior Brother Lin, you are really refreshing, thirty low-level spirit stones! Senior Brother Zhao can give as much as he asks, you won't bargain?" After paying the spirit stones, he and Wang Feng left the attic, and seeing that the distance was far enough, Wang Feng spoke.

Lin Shan's eyes kept on his feet, and he suddenly stopped, and after a while, he stared at his two big eyes, and said with an unwilling expression: "Can you still make a bargain?" Senior Brother Wang, why didn't you tell me earlier?"

"Ahem. I thought that you were born in the scattered cultivation circle, you must know the difficulty of earning spirit stones, this Dan furnace has a maximum of twenty spirit stones, Senior Brother Zhao should be happy to death, he has never sold more than twenty low-level spirit stones there. ”

Seeing Lin Shan's blushing face, the green tendons on his head exposed, and the look of desperate desire to go back to find Senior Brother Zhao, Wang Feng hurriedly grabbed Lin Shan and said: "I have already bought it, Senior Brother Zhao's items are often problematic, but maybe your Dan furnace is good, then it will make a lot of money, and our Xiaoxianfang around us, a low-grade ordinary Dan furnace will also cost hundreds of low-grade spirit stones!"

When Lin Shan heard this, he gradually quieted down, he thought that this Dan furnace had been carefully inspected, and he really didn't find any problems, it should be good, so his heart calmed down a little.

Thanks to Wang Feng, all the way back to the West Mountain Peak, Lin Shan hurriedly took out the black pimple Dan furnace from the aura bag, first carefully cleaned the mud on the Dan furnace with clean water, the lumpy color rust and other stains several times, and then took out the Huoyun Sword to carefully scrape off the remaining hard lumps, and was busy for most of the day, before cleaning this Dan furnace.

I carefully checked it from top to bottom, and found that there was indeed no corruption and hollowness caused by too much age, so I was relieved.

After his careful cleaning, the black Dan furnace finally regained a little of its true color, but it was like charcoal.

Black is black, as long as it can be used, Lin Shan exhaled, looked at it carefully and thought about the use of this Dan furnace, there is a lid on the hole in the furnace lid, remove the lid, expose the hole, look into the furnace from the hole, and find that this hole is facing the bottom of the furnace, think about it slightly, and figure it out, this should be used to deliver medicinal materials.

Lifting the lid of the stove, he took a closer look at the tray made up of many small black meshes, and found that although it had passed for an unknown amount of time, the mesh mouth was still very smooth.

"Could it be that this tray is used to hold medicinal herbs?" Lin Shan thought to himself.

"What is the net shape of the tray for?" Lin Shan secretly had a headache.

Gently close the lid of the furnace, the three transparent mirrors on the furnace body have been cleaned, through these three mirrors, you can clearly see the situation at the bottom of the furnace and the tray, I thought it was right, it should be used to observe the situation in the furnace during the alchemy process.

As for the two holes the size of an adult's palm, Lin Shan pondered for a long time, and suddenly remembered the stove where he cooked rice in the mountain village, which was also like a hole in the same way.

"Oh my God, does alchemy have to burn wood. Lin Shan had a smirk on his face, and he was speechless for a moment.

"Alas, it's hard to have a child with no one. He let out a long sigh.

Sitting in front of the Dan furnace, suddenly he gritted his teeth, stretched out his right hand, and generated a fire spirit bullet the size of a thumb head, and then gently hit the Dan furnace, the Dan furnace did not react at all, the fire bullet did not splash, and it was silently extinguished, and then Lin Shan generated a slightly larger fire spirit bullet, and hit the Dan furnace again, still no response, so after several times, Lin Shan violently attacked the Dan furnace with the largest fire spirit bullet he could generate now, and the Dan furnace still did not move at all.

After the fire spirit bullet was tested, Lin Shan used the wooden spear technique on the Dan Furnace again, but no matter how Lin Shan attacked, this Dan Furnace was still intact.

Now Lin Shan is finally completely relieved of the thirty low-level spirit stones, this Dan furnace has a very strong ability to absorb flames, has the most basic characteristics of a good Dan furnace, can resist his own wooden spear attack, and the defense is also good, the big deal is that he can't really refine the Dan in the end, so it is also a good choice to use it as a shield, fortunately, he can still accept the weight of this Dan furnace.

The problem of the Dan furnace has finally been solved, and the next step is to start learning alchemy.

Wang Feng said, Shimen Academy can consult the information, but to spend spirit stones, when I think of the spirit stone forest mountain, I have a headache, this wind spirit valley, is a money bag, everywhere has to be charged, no wonder many monks are not optimistic about it, get everything to get a spirit stone, if it is not for his trip to the Xuanbing area that almost died, after coming here, he can only meditate and watch the sky every day.

Lin Shan took out the remaining thirty low-level spirit stones from the spiritual qi bag and lined them up one by one, he couldn't wait to break these spirit stones into three or four pieces one by one, and only after a long time did he sigh, these thirty low-level spirit stones should be used well on the blade.
