Only half a day later, Yi Chengcheng found Hei Biao and handed him a bottle of elixir.

Hei Biao looked at the jade bottle in his hand, so many precious medicinal materials, can he exchange it for such a bottle of elixir, hey, what else can he do except endure it.

Without opening the jade bottle to check, Hei Biao reluctantly squeezed out a smile and said, "Thank you, uncle, for helping me refine the pill, there are still some materials for refining magic weapons here, and I have to trouble uncle!" ”

Although Hei Biao was 10,000 unwilling, he still took out some refining materials that were not of bad quality.

Looking at Hei Biao's smile that was more ugly than crying, Yi Cheng couldn't help but shake his head and smile, even if this demon beast gave birth to spiritual intelligence, it would no longer hide its emotions.

Facing humans looking at it is laughing, maybe the next moment it will stab you, but this demon beast can't hide its dissatisfaction.

Yi Cheng didn't care about Hei Biao's attitude, and dealing with demon beasts at least made Yi Cheng feel more relaxed than humans.

"Why don't you open it and take a look? Can't you trust my skills? Yi Cheng didn't care about Hei Biao's ugly face at all.

"This uncle, you don't need to look at it, your refining must not be bad." Hei Biao was about to cry by Yi Cheng's words, if he saw the pill, he couldn't help but scold it, and he wouldn't be picked up by this evil star.

"Grinding and chirping, it's really ridiculous!" Yi Cheng said a word, and the elixir was in his hands.

Then Yi Cheng opened the medicine bottle, and immediately a burst of fragrance filled his nose, Hei Biao couldn't help but take a deep breath, could this pill really reach the fourth grade, this human being did not lie to himself?

Hei Biao was thinking about it, but he heard Yi Cheng's voice ringing in his ears: "Innocent Pill, a fourth-order high-grade elixir, taking one pill a month, can remove impurities in the body, increase the absorption rate of spiritual power, and have some effect of refining the body." ”

"Fourth-order high-grade?" Hei Biao could barely believe his ears.

He snatched the bottle of elixir from Yi Cheng's hand, poured out one, and stuffed it into his mouth, and the elixir immediately turned into a warm current and entered his abdomen.

"This is really a fourth-order top-grade, great" Hei Biao showed an ecstatic expression, although he hadn't taken many pills, he wouldn't be wrong about this quality.

For so many years, Yi Cheng has been an uninterrupted alchemy refiner, studying formations, although this desolate ancient forest is full of hidden dangers, but it cannot be denied that this is definitely a paradise for alchemists, all kinds of herbs can be found, Yi Cheng has to refine several kinds of pills almost every month, and his rich experience cannot be compared even to those alchemy masters of the Great Gate School.

"Okay, what other materials are there, I will stay here for ten days, and I want to refine a batch of pills, and I will also practice for you what you need to refine, so as not to run to the holy land to beg for people. However, let me explain in advance that I charge one-third of all the pill materials as a fee! "Although Yi Cheng has something to do, he will not do a loss-making business.

The few times he has helped the demon beast refine the pill refining tool in these years, the price he charged is the same.

"Yes, yes, later, I'll show it to you." Hei Biao showed ecstasy, this was simply an alchemist falling from the sky, and he just hit himself.

Even when he arrived at the Holy Land, he asked those alchemists to refine the pills for himself, and it was not bad to be able to get half of the finished pills, and it was only a fourth-order middle grade or even a lower grade.

And what Yi Cheng refined turned out to be a fourth-order high-grade product, and he only charged one-third of the fee, and he would be a fool if he didn't take out his own precious materials, and this human didn't look like a person who would be greedy for his own materials.

I saw that this Hei Biao went to several courtyards in his cave mansion again, and when he came back, he handed over dozens of medicinal herbs to Yi Cheng, all of which were on top of the previous elixir.

Then he took out dozens of precious refining materials in his storage ring, although he didn't see the magic weapon of Yi Cheng's refining, but from the perspective of Yi Cheng's alchemy level, it shouldn't be too bad, even if it was really wasted, this Hei Biao also felt that he was not a loss, at least this pill was really high-grade.

"Hehe, it seems that you have a lot of good things, I will help you refine these things, you should be able to refine a set of full-body defense magic weapons, plus a pair of weapons, by the way, what are you used to?" Yi Cheng saw that this Hei Biao really regarded himself as a coolie, and he didn't care, there were so many good things for him to practice, he was naturally happy.

Hei Biao was a little embarrassed by Yi Cheng's words, how could he hide Yi Cheng's careful thinking before, so he took out a pair of plate axes from the storage ring, although the quality was not good, he had just reached the level of spiritual weapons, but he was powerful, and the three-foot-wide axe blade seemed to have a minimum of five or six hundred catties, which was powerful and heavy, and people did not dare to underestimate it.

Yi Cheng looked at this pair of plate axes, and also sighed secretly, looking at this material, it should be refined with Wanjun iron as the main material, Wanjun iron is a rare material, and the weight is extremely heavy, not to mention refining the lower grade spirit weapon, it is enough to refine the upper grade spirit weapon, but the refining level of this axe really makes Yi Cheng feel a little violent.

"Okay, if I refine this pair of axes, it should be able to reach the top grade." Yi Cheng looked at the axe and spoke.

Hei Biao showed an ecstatic expression: "Shangpin, thank you uncle, thank you uncle." ”

"Okay, don't call me uncle, as if I'm very old, my name is Yi Cheng, just call me by my name, before I get to the Divine Ape Clan, I don't want anyone to know my strength, you know how to do it!"

"Knowing the way, knowing the way, Uncle Yi is no, no, no, Yi Cheng!" Hei Biao was busy.

Seeing that Yi Cheng turned around to leave, Hei Biao said with some embarrassment: "Uncle Yi Cheng, I still have some medicinal materials, I haven't planted them in the cave again, I'll go get them now, I can get them back in three days, can you refine them into pills for me." ”

"Oh, and, well, you can just give it to me in three days." This black biao seems to be really moisturized by the king of the mountain, and good things are splashed one after another, and some of these are even Yi Chengcheng's eyes hot.

Back in the secret room, Yi Cheng sorted and placed the medicinal materials, refining the pills was already too ripe for Yi Cheng to be ripe, because there were a lot of them, Yi Cheng added and subtracted these pills, and it took a day for Yi Cheng to complete the refining of all the pills, a total of no less than ten kinds, all of which were pills that increased spiritual power or supplemented spiritual power by practicing on weekdays.

After doing this, Yi Cheng began to refine magic weapons again, because demon beasts are a little different from humans, they can not only turn into human form, but most of the time, they still have to fight with their own body.

Therefore, to refine magic weapons for demon beasts, it is necessary to make these magic weapons able to change their size and form.

The size of the change can be done even with ordinary magic weapons, but if you want to change the form, then it is more complicated.

However, Yi Cheng learned a method from the true solution of Tianyi Refining, that is, to add a very flexible metal when refining, thousand-tough steel.

This thousand-tough steel is extremely rare, and Yi Cheng only got a piece of half a zhang size after he looted the Kunwu Treasure House, which has long been used up over the years.

But in the Ancient Forest, not only are the demon beast elixirs abundant, but even the mineral deposits can be found everywhere, plus most of the demon beasts can't be mined, with the help of Xiao Jin, Yi Cheng really found a few good mineral deposits, and the Thousand Toughness Steel is one of them, Yi Cheng got hundreds of square meters of Thousand Toughness Steel there, so now there is no difficulty in refining this magic weapon.

On the third day, Yi Cheng not only finished refining this set of defensive magic weapons, but the pair of axes was also re-smelted by Yi Cheng, adding some other materials, and the quality had almost reached the peak of the spirit weapon.

And the materials given by Hei Biao, Yi Cheng only used less than half, even if he counted the things he added, there was still a small half of the balance, Yi Cheng naturally smiled unceremoniously, this thing given by Hei Biao, if it was put in the vast cultivation realm, it would all make those Yuan Infant Stage monks snatch their heads.

At this time, Hei Biao also returned to the cave, and when he saw the elixir magic weapon that Yi Cheng had refined for himself, he shouted with satisfaction, and he was a little unclever at Yi Cheng.

Immediately afterwards, without hesitation, he took out more than a dozen medicinal herbs for Yi Cheng, looking at their quality, all of them were 10,000-year-old elixirs, 10,000-year-old snow ginseng, Tianxin flower, and Agni Guts Yi Cheng looked a little excited.

And when Yi Cheng saw a purple spirit grass, he immediately showed a happy expression, for no other reason, because Yi Cheng got a pill in the Tianyi Dan Sutra, which could refine a cherished pill called Creation Pill.

The effect of this Creation Pill is miraculous, and it does have the effect of skillfully seizing the Creation of Chemistry.

Taking one pill, you can instantly replenish your spiritual power, and it does have the effect of creating the world.

It's just that Yi Cheng hasn't seen a single plant gather a material in the past ten years, because one of the main materials, the Nine Heavens Immortal Spirit Grass, has never been found.

This Nine Heavens Immortal Spirit Grass is said to be a thing in the spirit world, and it is extremely rare in the human world, almost a thousand years old.

However, the magical spiritual power contained in the Nine Heavens Immortal Spirit Grass can allow monks in the Transformation Stage and below to instantly replenish their spiritual power, and it can be said that it is definitely the top elixir in the human world.

Yi Cheng didn't hide his expression, and said to Hei Biao: "This spirit grass is of great use to me, I need to refine a pill, and I haven't found this main material, even if this herb is the cost of refining the pill for you, I'll give you one-third of the pill, okay?" ”

"Give me all the pills, just this one herb? Yes, of course! Hearing this, Hei Biao hurriedly agreed.

He didn't know this elixir, even if it was something precious, he wouldn't refine the elixir, but he had seen Yi Cheng's alchemy level, he didn't charge any fees for these elixirs, wouldn't it be that he could have one-third more pills, so the fool didn't agree.

Yi Cheng smiled and nodded, and gave Hei Biao the one-third of the pill he left behind.

Then Yi Cheng put away the Nine Heavens Immortal Spirit Grass and asked Hei Biao to take the rest of the pills a day later.
