The huge ancient texts seem to be suppressed by mountains in the sea of Niu Er's knowledge, Niu Er comprehended for a while, and found that there was also an auxiliary method, which was the inspiration that the immortal found another way and got from alchemy.

As we all know, the method of alchemy is to quench and extract the essence of plants and trees, and mix various spiritual substances together, and the medicinal properties interact with each other, which greatly stimulates its own properties, and becomes another unique property, which is of great benefit to the monks.

And the last method is to use the demon cultivation itself as a main medicine, assisting more than a dozen precious plants and trees, penetrating the bone marrow, giving birth to blood, and forcing the body to excrete excess impurities.

However, this method is not something that everyone can bear, but it needs to be soaked in the furnace and tempered with real fire, and the pain and suffering can be imagined, and it is unbearable for people who are not determined and persevered.

Grandma drops, Niu Er scolded secretly, I didn't expect to find a way to be so difficult, this is obviously torturous. Have the heart to give up, but it is difficult to give up the strength after success.

Gritting his teeth, Niu Er finally decided to give it a try, but he couldn't help it.

For three days in a row, Niu Er took two major servants and ran through more than 1,000 large pharmacies in Pengwang City, and even Long Xiaohai came to help, and turned over the medicine depot in Longfu, barely enough of most of the medicinal materials.

There is only one thing called Holy Blood Wood that cannot be found, not that this thing is too precious, but that there is no one in Pengwang City, or that there are not necessarily a few in the entire Pengwang Demon Domain.

Because the Holy Blood Wood is produced from a bloodthirsty demon tree, this tree does not cultivate human form, has no soul reason, only knows how to kill blindly, suck the blood of monks and grow vigorously.

At the end of antiquity, the mighty monk seemed to disappear overnight, and the bloodthirsty demon tree had no restrictions, and the seeds were all over the world.

Later, the anger of the people was aroused, and the monks of the world resisted together, using the great magic power to burn the branches of the demon tree, and countless formations sealed the heavens and the earth, and trapped and killed the demon seed to scatter, so as to completely eradicate this demon tree.

Until now, only in some desolate and barren places will there be a few remnants of the bloodthirsty demon tree, and after its main trunk is refined, it is the holy blood tree, which contains a large amount of pure blood qi. However, because it is too messy and impure, it is rarely used by monks.

"Brother Niu should be in a hurry, there will be an auction in the city in a few days, and there will be countless treasures and strange things displayed every year, and there will be an auction of this wood at that time. "Long Xiaokaido.

"It's a good opportunity. Niu Er groaned, the auction meeting of Pengwang City is incomparable every time, and the demon kings of all ethnic groups from Tiannan and Haibei take the opportunity to celebrate the birthday of King Peng, they can sell mountain specialties and buy some treasures they need.

"Brother Long, can you help Brother Niu get an admission post?" Niu Er asked, because there were too many people paying attention to the auction, and the tickets for admission were hot, and they were often noisy to a sky-high price, eager but unavailable.

"It's a trivial matter, Brother Niu can rest assured, this matter is on the younger brother. ”

Long Xiaohai patted his chest and said loudly, and then suddenly lowered his voice again, his eyes rolled around, seeing that no one was paying attention, his expression was extremely cautious, and he whispered: "Brother Niu, my little brother has an important matter to ask you." ”

"Oh, what's the matter?" said Niu Er in surprise.

"Hehe, on my last trip to Xianfu, my father found a few ancient prescriptions in the Xianzun Dan room, and the day before yesterday I had nothing to do and took a few random glances, and found that one of them turned out to be the legendary Zhuyan Danfang. ”

Long Xiaohai took two more steps, his face flashed a hint of redness, and he said excitedly: "Brother Niu, do you know that kind of elixir that can make people stay young forever, I know that Brother Niu is proficient in alchemy, so junior brother begs you to refine a few for me." ”...

"Don't worry, I have prepared ten medicinal materials for alchemy, and I ask Brother Niu to be merciful and help me with this. Long Xiaohai looked pitiful, pulling Niu Er's sleeve and begging, for fear that he would not agree.

Niu Er was shocked, he had heard of this thing, although it was not beneficial to cultivation, but it also made countless demon cultivators go crazy, every time one or two pieces were unearthed in the ancient cave mansion, they were all noisy to a sky-high price, comparable to a hundred thousand years of elixir.

This Chinese elixir has only one effect, that is, it makes the person who takes it look unchanged, and can stay youthful forever, even if it dies of old age, it will not change half a point, and it is a treasure that hundreds of millions of banshees dream of.

Demon cultivators and human beings in general, there are birth, old age, sickness and death, even if they achieve immortality of demon immortals, most of them are dying and old, looking old, and they need to protect their appearance with ** force. Thinking about the top beauties on those beauty pictures, once they grow old and are disgusted by the world, I am afraid it is enough to make them miserable, and even kill themselves.

This is a treasure, Niu Er's eyes flashed away, and suddenly gave birth to a way to make a fortune, and he couldn't help but swallow his saliva.

However, when he swept over Long Xiaohai, he found that there was a bit of strange flickering in the depths of his eyes, and he must have made his own little calculations, but it had nothing to do with him, so he frowned and said: "Every ancient Danfang is extremely difficult to refine, you give me the Danfang first, I will study it for a few days, and then I will open the furnace for you to refine the medicine." ”

"Thank you, Brother Niu, the medicinal herbs and the pill are here. Long Xiaohai couldn't wait to take out a storage bag, stuff it directly into the second-hand cow, and then say hello and run away.

"The younger brother will go back to the mansion first, don't disturb your alchemy, and come back to visit Wushan Pavilion the next day. ”

Niu Er looked at the direction in which Long Xiaohai disappeared, the corners of his mouth turned up slightly, this was not the direction of going to Longfu at all, and he thought that he was reporting the good news to the beauties of a certain big clan.

Back in Wushan Pavilion, Niu Er took out the storage bag given by Long Xiaohai, which contained ten square jade boxes, each of which contained a variety of herbs and trees elixirs, and the quality belonged to the best spiritual objects.

There are also a few jade slips in the corner, Niu Eryi looked at them one by one, and found that these are ancient Danfang, and they are very valuable. According to its efficacy, Zhu Yan Danfang is still the lowest storage zài among them, and it is estimated that this kid does not know the value, so he sent it all to him.

After all, the Dragon Mansion helped a lot, and Niu Er didn't delay, picked up the Danfang and began to study it carefully. Then for the next few days, the roar of the furnace was heard from time to time in the stone chamber, and the smell of burnt smoke came out, which frightened a group of little demons into a detour, and they did not dare to approach at all.

In the early morning of the fifth day, a strange fragrance spread for dozens of miles, and the monks of half the street flocked to it, thinking that Wushan Pavilion had added new delicious dishes.

But in the backyard, Niu Yu, Long Xiaohai and others all gathered outside the door of the Dan room, staring at the door with blank eyes, not daring to make a sound, for fear of affecting Niu Er inside.

"Click-"

The half-zhang wide stone door opened, and Niu Er, who was full of tiredness, strode out of the Dan room, holding a white jade porcelain bottle in his hand, although his expression was slightly sluggish, his pupils were shining.

"Brother Niu, did you succeed?" Long Xiaohai asked excitedly, holding the jade fan in both hands, almost twisting it into two pieces.

Niu Er nodded and said, "In the end, I lived up to my brother's expectations, and I barely succeeded in a furnace and took it." ”

Taking the jade bottle, Long Xiaohai opened the bottle with trembling hands, and found that there were a total of six soybean-sized pills, all of which were crystal clear, colorful and glowing, and the spiritual light was shining non-stop, and a rich fragrance penetrated deep into the heart and spleen, and at first glance, it was not ordinary.

"Thank you Brother Niu, Brother Niu's great kindness and little brother are unforgettable, and there will be a good reward in the future. Long Xiaohai bowed solemnly, his expression was quite strict, but it made Niu Er confused, isn't it just a pickle girl, why is it so strict. ...

"Don't say anything, you will be my brother in the future. This is your invitation, I still have important things to do, so let's go first. ”

Throwing a storage bag from Niu Er, a green cloud rose at Long Xiaohai's feet, and it disappeared in the blink of an eye, leaving the Niu family's uncle and nephew staring at each other speechlessly.

"Ahem...... , the second son, you can also give the second uncle two of those things. Niu Yu coughed, his face showed a little twist, and he pretended to be very strict.

"Ah, why didn't the second uncle say it earlier, I gave it to Brother Long. Niu Er spread out his two big hands, his big black eyes turned around, and he said very sincerely.

"Fart. ”

Niu Yu glanced at it and said disdainfully: "Second Uncle doesn't understand your skinny nature, that is, the iron rooster has to hang a few catties of iron filings in your hands, do you dare to say that there is no private collection?"

Niu Er was speechless, this is really the second uncle, even this little trick is clear, in desperation, he had to take out another jade bottle, and said painfully: "The little nephew only left three grains, give one to the second uncle, I wish the uncle eternal youth." ”

"No, two, otherwise you kid will want to take away half more elixir in the future. Niu Yu spread out his big hand, stretched out directly in front of Niu Er, and raised two thick fingers, which frightened his eyes and almost fainted.

This is a naked robbery, Niu Er wants to cry without tears, who let this be his own uncle, the power in the mountains is in his hands.

Seeing Niu Er's hesitation, Niu Yu raised the corners of his eyebrows slightly, and said very casually: "The spider is not small, it's time to find a suitable Taoist partner for her." ”

"Don't, don't worry, second uncle, nephew will give it to you. Niu Er was so frightened that his heart jumped, and he hurriedly sent the two Zhuyan Pills to Niu Yu's palm with a sad face.

I sighed again and again in my heart, this second uncle is really dark! The original plan to leave it to Spider and himself is gone, and it is estimated that I can only open another furnace, but those medicinal materials are really expensive.

Three days later, the annual auction of Peng Wang City began grandly, and it was said that the Quartet Guards under the Peng Demon General sat in the venue to prevent accidents. In addition, all the top wealthy families have high-level figures, and the atmosphere of the whole auction is quite warm.

Originally, Niu Er planned to take the three brothers of Yuan Kong with him, but he never thought that the three of them were hot-blooded young people, and he didn't know what stimulation he had, so they all went to the martial arts arena to compete, and they had to leave a name on the hero list before they stopped.

And Niu Yu disappeared early in the morning, Xiang Yusheng and Niu Dahei were also sent out of the city by Niu Yu, and in desperation, they had to take the spider and the rat demon to go.
