Sure enough, it is worthy of being an alchemy laboratory that only a fourth-order alchemist can use. Dongfang Xiao couldn't help but sigh, he thought that the third-order alchemy laboratory he used was already quite good, but compared to the current fourth-order alchemy laboratory, it was a drop in the bucket.

After taking a brief look at the alchemy tools, Dongfang Xiao no longer hesitated, took out his own materials, and began the refining of the alchemy potion.

"The materials he took out were a little peculiar, it seemed to be a very special alchemy formula, at least I had never seen it." An alchemist was a little surprised when he saw the materials that Dongfang Xiao had taken out, the formula of the fourth-order alchemy potion was very rare, a brand-new alchemy formula was very important to the guild, for most alchemists, the alchemy formula they learned was basically the same, but some key materials were different.

"That's true, I've never seen this recipe before." The other alchemists also whispered, because of the formation shielding, Dongfang Xiao naturally didn't know the reaction of these alchemists, and he was already immersed in the world of alchemy, so he didn't have the heart to pay attention to anything else.

Gu Ling observed more carefully, and said after a while: "Not only is the formula a little different, but his alchemy technique is also a little different from that of an ordinary alchemist. ”

Many alchemists also paid attention to Dongfang Xiao when they heard this, alchemy has developed so far, alchemy techniques have basically been completely finalized, only some ancient inheritances will use some unique alchemy techniques, these unique alchemy techniques generally have a very unique effect, and have a very strong attraction for high-level alchemists, even if they just watch this unique technique, it has great reference significance for their alchemy.

"It seems that it is the right decision to participate in this assessment today." Many alchemists sighed secretly in their hearts, the originally whispered discussion had completely disappeared at this moment, and all the alchemists, including Gu Ling, set their eyes on Dongfang Xiao's body.

The potion that Dongfang Xiao intends to refine this time is not just one, although it is said that as long as he can refine one elixir, he can meet the requirements for promotion, but he can only look at the promotion to the fourth-order alchemist, if he can refine a variety of fourth-order elixirs, then he can be promoted to a fourth-order intermediate or high-level alchemist. And Dongfang Xiao chose to refine the first HP and MP elixirs at the human level, although these two elixirs can also be regarded as reaching the category of fourth-order elixirs, but the level in alchemy is only lv2, and the difficulty of refining is also slightly lower, just used to practice hands first. There are three main materials required for human-level HP elixirs, namely wild ginseng, breath of life and gold powder, as well as dozens of other various auxiliary materials, these materials may not be very precious, but there is a characteristic that is very unique, and some people are surprised that such materials can be integrated into alchemy.

"Can daffodils still be used in alchemy? It's unexpected. ”

"Yes, there are also firefly wings, which are actually a kind of alchemy material."

The alchemists began to whisper again, each alchemical material has its own properties, but no one dares to say that the properties of a material have been fully studied. There was once an alchemist who wanted to improve a fourth-order potion, but after experimenting with thousands of materials, he was unsuccessful, and he himself believed that the improvement of this potion had reached the extreme, and there was no room for improvement. By chance, when refining the potion, he accidentally refined the petals of a morning glory into this potion, he thought that this bottle of elixir should have failed, but he never expected that the effect of this elixir not only did not weaken in the slightest, but became a lot stronger, and later after the research of this alchemy master, he finally researched a more powerful fifth-order elixir on the basis of this fourth-order elixir, which became a beautiful talk in the history of alchemy. Alchemy is like this, some seemingly ordinary materials, sometimes in alchemy, can play an effect that other rare materials can't achieve.

Dongfang Xiao felt that the alchemy state this time was very good, about half an hour later, a tube of bright red elixir was refined for him, this is the master HP elixir he successfully refined, this time he did not go through any failure, and directly succeeded in refining this elixir, which made him very happy, if this state can continue, the success rate of the next elixir refining will be much higher.

Dongfang Xiao carefully took out a bottle with a strange shape from the space bag, different from ordinary potion bottles, the potion bottle taken out this time was a cross, which looked very peculiar, Dongfang Xiao poured the potion into the bottle, and then put the bottle on a small magic array on the realization platform, the silver light flashed, and the bottle was teleported to several alchemists, and Dongfang Xiao had no intention of leaving, ready to start refining the next potion.

"Are you ready to start refining the next potion?" Everyone is not surprised by Dongfang Xiao's behavior, for many alchemists who participate in the promotion exam, most of them will refine all the potions that they can refine that can be used for promotion, but this is not easy for most alchemists, it is not easy to be able to refine two or three, and some alchemists will first refine some low-level potions for practice when they are promoted, and only then will they start refining high-level potions until the end, However, now that Dongfang Xiao has chosen to teleport this bottle of elixir, this means that Dongfang Xiao thinks that this elixir has reached the level of a fourth-order elixir.

"Human-grade HP potion."

Several alchemists were a little surprised to see the name of this potion, since this bottle of potion has different grades, it means that this potion should be a series of potions, and this potion is also something they have never seen before, and the meaning of this is somewhat extraordinary.

And Belus was no stranger to this kind of potion, and hurriedly began to explain the effects of this kind of potion to all the alchemists.

"Is it a medicine that can quickly replenish vitality without any side effects? Among the elixirs that can restore vitality, this elixir is also very precious. Gu Ling's eyes showed a hint of solemnity, and said, "Don't waste any more time, let's start the determination of the potion immediately." ”

For such a group of fourth-order alchemists and a fifth-order alchemist, it was still very easy to determine a potion, and it only took ten minutes to determine that this elixir had indeed met the requirements of a fourth-order elixir.

Gu Ling looked at Dongfang Xiao, who was still refining the potion, and let out a long sigh, no matter whether Dongfang Xiao's next refining of the potion was successful or failed, he could be sure that he had been able to successfully advance to the fourth-order alchemist.
