The alchemy rooms at the foot of the mountain are all of the most common kind. There are only two different grades of alchemy rooms, flame and furnace. However, most alchemists choose the alchemy room to make elixirs, which is nothing more than a plan. The tranquility, the flames and the cauldron were all prepared by myself. The same was true for Ye Yu. He directly ignored the bronze cauldron in the alchemy room and took out the big cauldron brought from the back mountain. He took a deep breath and sat cross-legged in silence for several hours, adjusting his energy and spirit. Only when you are in the best condition can you start preparing to take action. In order to refine the elixir, he has spent a lot of effort on it these days. Of course, the elixir recipe of Juqi Powder cannot only have clover. In addition to clover, there are other ingredients, but these medicinal materials are not of high value. It is enough to get these things from the sect's warehouse with the contribution points gained from killing monsters. Ye Yu looked at the big cauldron in front of him, his eyes flashing. To be honest, he didn't have full confidence in this big cauldron. After all, Mu Yue's statement was just speculation and had not been confirmed, and he only had this piece of information at hand. , If you fail to practice, you will really want to cry without tears. Looking at the bronze cauldron on the side, Ye Yu sighed. The effect of alchemy in the bronze cauldron was not very good. Even if he controlled the earth fire more skillfully, with his first alchemy method, he had no idea about the alchemy process. If you are not familiar with it, it will be difficult to refine elixirs with pure spiritual power. Even it is not impossible to blow up the furnace! When monks make alchemy, furnace explosion is a common occurrence. The temperature in the furnace is too high, or the spiritual energy of the medicinal materials are gathered together but cannot blend with each other, which may cause the furnace to explode, especially for novice alchemists. The most normal thing. Ye Yu struggled for a while, gritted his teeth, and chose his own cauldron. With a bronze cauldron, it was difficult for him to guarantee success, so he might as well give it a try. Ye Yu rolled up the sleeves of his robe, and various medicinal materials were rolled up by his true energy and automatically thrown into the furnace. At the same time, he exhaled the true energy from both hands, and the earth fire heated the alchemy furnace with the true energy, and the magical power of the earth fire was immediately revealed. Showed up everywhere! Under this ultra-high-temperature flame calcination, various medicinal materials are quickly refined, and the impurities in them are incinerated into ashes. The medicinal power in the alchemy furnace becomes increasingly pure! The advantage of flames was fully revealed at this moment. If it were just ordinary flames, it would take longer to refine the medicinal materials. Moreover, with his cultivation level, even using all his true energy might not be able to refine the first-level medicine. Clover refining, because it takes a long time, his true energy is insufficient, which is also the main reason why many low-level alchemists cannot refine high-level elixirs. Generally, ordinary flames are used to refine the first-level Qi Gathering Powder. It requires at least five levels of Qi training to refine it, but with Earth Fire, this problem is easily solved. And because the temperature of the ground fire is high, the impurities in the medicinal materials are quickly separated. The fewer impurities in the medicinal materials, the purer the potency of the elixir, which means that the higher the grade of the elixir. "Although the temperature of the earth fire is high, it is not pure. It is unrealistic to remove all impurities. It would be good if a furnace of middle-grade elixirs could be produced. I only hope that this cauldron can be powerful." After a series of processes, The situation was excellent, and Ye Yu's worries were a little relieved. This alchemy was not as difficult as imagined. As long as the flames were controlled, the chance of success was still high. He didn't know that just controlling the flames had stumped many alchemists since ancient times. Others didn't have his natural sensitivity to flames. Sometimes the temperature was high and sometimes it was low in the blink of an eye. He was the only one with such a natural sensitivity. Only those with the power to control fire can play with flames so freely. The earth fire rolled in his hands, and as the situation in the cauldron continued to adjust, it was often the case that there was some minor situation in the cauldron, and he would be able to respond well the next moment. In this regard, he has even surpassed many immersed people. An alchemist who has practiced alchemy for many years. The sound of refining the elixir in the cauldron gradually turned into silence. Ye Yu took a deep breath. This was the most critical moment when the medicinal power was condensed and ready to be turned into elixir. The scorching Qi in his body quickly gathered, and all the Qi in his body poured into his palms. Under the stimulation of the Burning Heaven Technique, the temperature of the earth fire suddenly rose, and with a cry, a fire snake several meters high jumped up. Ye Yu felt nervous after firing out this last burst of energy. If refining medicinal materials is the stage where the furnace is most likely to explode, then making pills is the stage where waste pills are most likely to be produced. After waiting for a moment, I heard the crisp sound of beads falling on the jade plate from the alchemy furnace, so I opened the alchemy furnace, and a fragrance hit my nose. I saw more than ten pieces of concentrated energy scattered in the alchemy furnace, rolling back and forth, crystal clear. , bright color. "It's done!" Ye Yu was overjoyed and picked up a Qi Gathering Powder. Feeling the power of the medicine, he suddenly felt a shock in his heart: "High-grade elixir?" Ye Yu was deeply shocked. For ordinary people, the probability of an explosion in the alchemy furnace for the first time was extremely high. Big, very few people can defecate for the first timeThe finished product, even if it is refined, is low-grade elixir with extremely high impurity content, medium-grade elixirs are rare, and high-grade elixirs are simply rare. If other people knew that he had made a high-grade elixir without any impurities for the first time, they would definitely exclaim and call him a monster! The classification of elixirs is generally that if the elixir contains 50% to 60% of impurities, it is considered a low-grade elixir, 30% to 40% of impurities is considered a middle-grade elixir, and 10% to 20% of impurities is considered a high-grade elixir. If there are no impurities, it is considered a top-grade elixir. As for the elixir containing more than 60% impurities, then the elixir is useless, which means that the alchemy has failed. Although the difference is only 10% or 20% of impurities, the effect of the refined elixir is completely different. Every time it goes up a grade, the efficacy of the elixir is at least 50% higher, and if it is the best grade Dan, that value has soared. Ye Yu woke up from the shock, and immediately felt ecstatic. The high-grade pills were not only powerful, but also valuable. Thinking about it, six high-grade pills allowed him to break through from the second level of Qi training to the peak of the third level. This furnace Twelve high-grade elixirs were enough for him to move toward the fifth level of Qi training. "This is still too little clover. If it is a clover that is more than a hundred years old, the number of pills in this furnace will be at least doubled. The public price of a high-grade Qi Gathering Powder is ten contribution points. If you exchange it for a spirit The stone is ten pieces, that is to say, I only used it for a while and harvested one hundred and twenty spiritual stones?" Ye Yu looked at the spiritual pill in front of him with some dizziness. This wealth is really huge, so huge. He couldn't believe it was true. He had heard that the alchemist was the richest person in the world of cultivation before, but he didn't have an intuitive concept. Only now did he know how rich the alchemist could be. Qi Gathering Powder is a first-grade elixir. In terms of value, it ranks second to last among all elixirs in the world of cultivation. Even a boy like him, who is on the third level of Qi training, can make it. It shows that the value is not high. If it were higher The value of elixirs at this level will inevitably increase exponentially, and the amount of spiritual stones earned by then will be an astronomical figure. Ye Yu carefully put the elixir into the jade bottle that he had prepared in advance, for fear of making any mistakes. Only after everything was prepared, he was in the mood to check the cauldron in front of him. There are still some white powder residues in the cauldron, which should be where the impurities are. Looking at this situation, the earth fire has indeed not refined all the impurities in the medicinal materials. Thinking of the scene in the dense forest at the back of the mountain where the Butterfly advanced, Ye Yu's heart was shaken, knowing that Mu Yue's speculation had come true. This cauldron must have the function of gathering medicinal power, gathering the pure medicinal power together, and then mixing it. Only after using his Earth Fire did he develop the high-grade elixir. When thinking of this, Ye Yu was ecstatic!
