"This guy wants to me......"

Lei Ren groaned slightly, he was no longer the alchemy rookie who didn't understand anything at the beginning. Pen & Fun & Pavilion www.biquge.info

On the contrary, at that time, in order to find a suitable Dan prescription to earn spirit stones, the Dan prescriptions he had studied were all difficult to write, although those were all pills in the Qi Condensation Period, but in principle, they were no different from those in the Foundation Building Period.

So after seeing Ye Xiao's first three materials, he thought about it for a while in his mind, and he thought of at least thirty combinations.

Merely...... When the last Qingxu Immortal Grass came out, the feasibility of his thirty kinds of Dan recipes was all greeted with a hello.

After all, this Qingxu Immortal Grass is generally regarded as a poisonous weed, and is used to refine some elixirs that tame spirit beasts.

"Hmph, boy, what are you still grinding, the competition hasn't started yet, you have to admit defeat?"

Ye Xiao laughed contemptuously, the strategic nature of the duel battle is reflected in this kind of place, different from the usual refining medicine, as an opponent, it is the best way to win by making some tricky materials difficult for the other party.

And he knows a lot about this Clear Void Immortal Grass, and he is completely sure to eliminate the negative impact, and this time he took it out just to disgust Lei Ren.

"Hehe, don't be complacent, you still have to think about what kind of Dan you want to practice later, these are my materials. ”

Lei Ren smiled indifferently, there is a strategy for the duel battle, but the materials are fair to both sides, so although he doesn't have a clue for the time being, it's not very empty.

As for the previous Xianyin Mountain group, there was not much else in his storage bag, but the second-order top-grade spirit grass had collected hundreds of kinds, and after a little consideration, he took out his own four materials.

It's just that his shot made the entire second-floor onlookers stunned!

"Dragon Fruit, Sword Flower, Purple Blood Vine...... It's all rare, and all of them are second-order best training materials, hmm, and the last one is ?......."

In the second layer, everyone is in the foundation building period, even if they are not alchemists, they often take pills, naturally all of them are knowledgeable, but as soon as Lei Ren's last material was taken out, everyone was stunned.

A group of people, you look at me, I look at you, after a long time, since I haven't been able to recognize what this is.

"Leyline Source Crystal?"

The white-eyed elder was also stunned, because the thing was still in Lei Ren's hands, so he also sensed it in the air for a while before he dared to be sure.

But the earth vein source crystal is really too rare, and it is generally like the six major sects use the resources of the sect to refine, and they can't refine much at all, so the people present didn't think about this aspect at all at first.

After hearing the elder speak, everyone looked suddenly enlightened, but the next moment, their expressions became longing.

"Obediently, it's really the leyline source crystal, I went to the spiritual abyss back then, and felt the earth's leyline aura, that's what it felt! It's just that this source crystal gives me the feeling that it is countless times more refined! If this can be used for cultivation, my foundation can definitely be strengthened. ”

In the crowd, there was a disciple of the fivefold leyline foundation who said enviously, the leyline source crystal was not only expensive, but also a rare resource that could not be found, they never thought that Lei Ren would actually take it out and use it for the decisive battle.

"Although it is rare, this source crystal is not big, but even so, I am afraid that if you ask for a hundred thousand tributes, there will be a lot of people who want it. ”

The other person said, and Lei Ren listened to it in his ears, and he also slightly approved.

In fact, he only picked off a small piece of fragment from a piece of source crystal in his storage bag, and in general, it was only one-twentieth of the piece he obtained in the Yinyue Sword Sect, even if it was a complete source crystal, he still had dozens of pieces.

But this is enough, although he doesn't care, but he only refines two pills, there is no need to take out a whole pill.

“...... Are you, boy, crazy?"

Ye Xiao was stunned, after all, this ambergris grass was only worth a total of how many tributes, although they said that they could use half of the materials they took out for themselves, and they could also get half of the opponent's, and only a fraction of the spirit grass was needed for a refining of medicine, so in fact, the total cost of a decisive battle was only tens of thousands of tributes.

And these tens of thousands of tributes have the opportunity to practice hands, and if the refining is successful, not only will they be appreciated by the elders, but the elixirs they have practiced can also be sold, so they will not lose money.

But Lei Ren took out such a precious material...... It looks like it's a solid loss.

"Earth Vein Source Crystal Alchemy, it's rare, how much do you want to use this piece?"

The white-eyed elder raised his eyebrows slightly, he was not surprised by the value, but the leyline source crystal is a kind of spar, although it is not said that it cannot be used in medicine, but the difficulty is definitely higher than that of ordinary medicinal materials, so much so that he doesn't know where to go, but he didn't expect that after Ye Xiao made a ruthless move, Lei Ren actually continued to increase the difficulty without fear.

If this continued, he even felt that this duel battle might be beyond the control of the second-order supreme alchemist.

"This piece is all used, Brother Ye has taken out the Qingxu Immortal Grass, I can't be stingy, anyway, no matter what, I will become a Dan in the end, and I won't lose anything." ”

Lei Ren said confidently, looking at Ye Xiao with a relaxed smile, but let Ye Xiao snort coldly.

It's just that he no longer has the composure he had before, because this leyline source crystal, he is in contact with it for the first time, and he is not sure that he will be able to become a Dan at all, and since Lei Ren dares to say this, he must be very familiar with this source crystal, but he didn't expect that he fell into a disadvantage before the battle of the decisive battle began.

On the other side, the white-eyed elder reached out and took the materials of the two of them, and handed them to the two of them after dividing out two copies of exactly the same amount of materials, but just before starting the alchemy, he found that Lei Ren's chest was still empty.

"By the way, Lei Ren, since it's a Dan Dao duel, hang out your badge as a sign of respect. ”

The elder said, but when Lei Ren heard this, his face turned dark......

"Hahaha, boy, don't be afraid, you are only in the middle stage of foundation building, everyone can understand the low level, and I will use these materials to refine the second-order best elixir, if you say, reduce the weight a little, refine a second-order high-grade, or medium-grade, and no one will laugh at you." ”

Ye Xiao's eyes lit up, he was still worried about how to refine the pill before, but when this elder mentioned it, he remembered that the other party's cultivation was lower than his own, and he should not be a second-order supreme alchemist, so in this decisive battle, he still had a lot of advantages.

"Uh...... There's no need to reduce the amount, just hang it up......"

Lei Ren's face flushed slightly, and he turned his hand and took out a small badge from the storage bag, which was the same as Ye Xiao's badge, and there were four marks, but the difference was ......

Ye Xiao is four green stars, while Lei Ren's is a four-leaf grass......

"Poof!-"
