In the alchemy room, a dozen alchemists sat together, staring at the boy intently.

  These alchemists were not young anymore, most of them were over 40, and the youngest was in his 30s.

  Now seeing a 15- or 16-year-old boy claiming to make an elixir, everyone was surprised and couldn't help but be a little unbelievable. Some people even shook their heads secretly, with a hint of mockery in their eyes.

  However, they were all clear-sighted people. They had heard that Master Yunqi had specially given a young man an alchemist nameplate. Although they didn't know whether it was true or not, no one would be stupid enough to mock him rashly.

  "Long Chen, although I am the president, I can't break the rules. If you want to advance the medicinal materials, you need to make the elixir in front of all the alchemists, and then we will decide the amount you can withdraw each time based on the quality of the elixir," said Master Yunqi with a serious face.

  "I understand, kid."

  Long Chen expressed his understanding of this matter. After all, the Alchemist Guild is not a personal industry. With Master Yunqi's style, he will never give him special treatment.

  "Here are 187 recipes for first-level elixirs. You can choose any one." An alchemist handed over a piece of animal skin paper, with a little gloating in his eyes.

  The elixirs recorded on that piece of animal skin paper are not ordinary first-level elixirs. The difficulty is in the middle and upper level among first-level elixirs. The success rate of ordinary alchemists is not high.

  What's more, refining elixirs in front of all the alchemists, and there is a master like Yunqi present, it would be strange if you are not nervous. In such an atmosphere, it is very difficult to successfully refine a finished elixir.

  The man who handed Long Chen the animal skin paper was also an alchemist. He was in his forties. When he was assessed for the advance quota, he failed seventeen times before passing.

  Everyone present was not much stronger than him, and basically they had to use it more than ten times before they passed the test.

  It can be seen that it is not an easy task to advance medicinal materials from the union, but once it succeeds, it will be much more convenient.

  Long Chen looked at the animal skin and pointed to the last pill recipe and said, "Let's take this one."

  "What? Are you sure?"

  The man said with a strange look on his face that the pill Long Chen chose was called the Violent Pill, which is an extremely domineering pill.

  It can make people burst out with powerful combat power in a short period of time, and it can almost increase people's combat power by nearly 30%.

  The Violent Pill is the most beloved thing for adventurers, although after using the Violent Pill, people will enter a weak state for a long time and leave a lot of sequelae.

  However, for them who live under the claws and mouths of monsters all day long, the Violent Pill is undoubtedly a life-saving treasure.

  However, it is very difficult to refine the Violent Qi Pill, which contains several extremely powerful medicinal materials. Even experienced alchemists rarely refine such pills.

  After all, refining pills is risky. Although the price of pills is extremely high, the materials are not given for free. They are all money.

  Moreover, the medicinal materials of the Violent Qi Pill are extremely expensive. If the refining fails for three consecutive times, the alchemist will lose money.

  So there are not many people who refine this kind of pill. After all, the adventurers cannot afford the high price of medicinal materials. If the adventurers are really rich, who would be willing to take risks?

  "Yes, it is this one," Long Chen said lightly, ignoring the gloating in the man's eyes.

  Master Yun Qi smiled slightly and asked a medicine boy to prepare three sets of medicinal materials. This is the rule of the assessment. There are only three sets. As long as one set is successfully refined, it will be considered passed.

  When the three medicinal materials were neatly placed in front of Long Chen, Long Chen took out his alchemy cauldron without any hesitation, and a light yellow flame rose in his palm.

  After a breath of time, Long Chen slowly moved the power of the alchemy fire under the medicine cauldron to heat the cauldron. After heating the cauldron, it was time to open the cauldron. The so-called opening of the cauldron means that after the cauldron is heated, the alchemy fire is driven by the power of the soul and wanders around in the cauldron.

  The advantage of this method is that the medicine cauldron can be completely put into the alchemy state, which can reduce the risk of the cauldron exploding and warm the medicine cauldron.

  You could be reading stolen content. Head to Royal Road for the genuine story.

  In fact, Long Chen has more advanced methods, but he has to use the most basic techniques learned in the Alchemist Guild.

  He doesn't want to make himself too amazing, which will be detrimental to his future. If someone secretly has bad intentions, it will be purely troublesome for himself.

  Everyone originally looked down on Long Chen, but seeing Long Chen's actions, which were very standard and mature, the contempt on everyone's faces gradually decreased.

  After all the preparations were done, Long Chen did not hesitate and directly put a piece of iron wire grass into the cauldron to start refining.

  Long Chen's action immediately turned the interest that had just risen in many people into ridicule.

  It takes the longest time to refine the iron wire grass, and it is usually placed in the middle and late stages, and then refined after the medicine cauldron is completely heated.

  However, only Master Yunqi had a strange look in his eyes and nodded secretly.

  What surprised everyone was that the iron wire grass had just been refined halfway and had not yet completely formed into powder. Long Chen took it out of the cauldron and put it aside, and began to refine other medicinal materials.

  When the sixth medicinal material was refined, Long Chen continued to refine the iron wire grass, but it was still not completely refined, and began to refine other herbs.

  This move puzzled everyone, but seeing the admiration in Master Yunqi's eyes, everyone couldn't help but be shocked. Could it be that this kid had some tricks in his method?

  Long Chen's iron wire grass was refined thirteen times before it was considered complete. At this time, more than twenty kinds of medicinal materials had been refined.

  Under normal circumstances, ordinary alchemists would adjust their breathing at this time to relieve their nervous spirit.

  But Long Chen didn't have that time to waste. After refining the essence of the herbs, he started to refine the pill directly, putting one medicinal material after another into the pill furnace.

  What everyone couldn't figure out was that Long Chen pressed the essence of the iron wire grass several times before putting it into the medicine cauldron.

  "Huh"

  The soul power was running, the pill fire rose rapidly, a scorching air wave came, and Long Chen began to refine the pill.

  "What a powerful soul power"

  Everyone couldn't help but be shocked, but at the same time they shook their heads secretly. If they started to increase the firepower at this time, what would they use to gather the pill when the pill was formed? Young people are young people after all, and they are too impatient.

  Master Yunqi looked at the young man with great interest. He was the only one who understood the meaning of Long Chen's actions. He liked Long Chen even more. A strong soul and hard work would make it easier to achieve results.

  What everyone didn't expect was that after half an hour, Long Chen's soul power did not stop at all. Instead, it became more and more powerful.

  "Bang"

  With a sound, the medicine cauldron vibrated slightly, and a strong wave came. Everyone's heart tightened. They all knew that this was the critical moment.

  The medicine cauldron kept making noises. Logically, at this time, the alchemist should slow down the power of the pill fire and stabilize the medicine cauldron.

  But Long Chen did not slow down. Instead, his soul power increased, the pill fire became hotter, and the noise in the medicine cauldron became more intense.

  "What is he doing?"

  Some people couldn't help but change their faces. This was not alchemy. He was doing this to blow up the furnace. This was clearly intentional.

  "Boom"

  Another explosion sounded, and the medicine cauldron was lifted. Long Chen suddenly put a big hand and pressed tightly on the lid of the cauldron. Suddenly, a powerful soul force broke out with all his strength.

  "Bang"

  The violent cauldron stopped violently, fell to the ground, and returned to calm.

  "This lousy method is really hard."

  Long Chen wiped his sweat. It was so tiring to refine the elixir with this method. The main thing was that he couldn't reveal his strength. He could only do it in a rigid manner. Long Chen had no words to say.

  Pop!

  The lid of the cauldron was gently lifted, and a strong fragrance of elixir instantly filled the whole hall. Everyone was shocked.

  "It actually succeeded."

  All the people present were experts. They didn't need to look inside the cauldron. Just smelling the fragrance of the elixir, they knew that Long Chen succeeded. Many people were shocked.

  "Very good, there should be at least one medium-grade pill inside"

  Master Yunqi looked at Long Chen with admiration in his eyes. Long Chen was beyond his expectation this time.

  He knew that with Long Chen's soul power, it should not be difficult to successfully refine pills, but he really wanted to know what Long Chen's foundation was.

  Today, he saw that Long Chen's basic skills were extremely solid, and he was not inferior to some alchemists who had practiced for many years.

  The most valuable thing is that Long Chen knows pharmacology very well and understands that the strong medicine of iron wire grass needs to be refined several times. Reducing its fierceness will make the pill more effective and have a higher success rate.

  This refining method is not known in the current Alchemist Guild, but some predecessors in the Guild's secret book library have recorded this experience.

  Unfortunately, the record there is very vague, and it only expresses a theory: after repeated refining of iron wire grass, its fierceness should be reduced.

  However, most of those experiences were very common methods, or some immature ideas. How many alchemists are so great that they would share their hard work with others for free?

  No one else would tell him, even Master Yunqi knew the way to extract the iron wire grass, but he never mentioned it to anyone.

  One is that he has no obligation to teach others, and the other is that as an alchemist, if he doesn't even dare to innovate, he won't be able to achieve anything great in his life.

  When everyone heard what Master Yunqi said, they were shocked: middle-grade elixir? Is this possible?

  Seeing everyone looking at him, Long Chen smiled slightly, waved his hand, and with his soul power, five full and round elixir appeared in his hand.

  Two of the elixir had very eye-catching patterns printed on them - elixir patterns, which are the characteristics of middle-grade elixir.

  For a while, the whole audience was silent. Except for Master Yunqi, everyone's eyes were full of shock, envy, and of course a hint of jealousy.

  Looking at the five pills in his hand, Long Chen breathed a sigh of relief. At this moment, Master Yunqi said: "Long Chen succeeded in refining the pill, and was granted the second-level credit."

  Master Yunqi's words made everyone's eyes change suddenly. The second-level credit, that is the right to advance the second-level pill, which makes people jealous.

  From the complicated eyes of the crowd, Long Chen followed Master Yunqi and left the hall. Master Yunqi suddenly said to Long Chen seriously:

  "Long Chen, be careful of that woman"
