If the first palace test is danxiu''s courage to face difficulties, then the second palace test is danxiu''s foundation of making Dan in various realms, and the third palace test is danxiu''s accumulation of understanding of plant properties.


    Brush! Just as ye Lingfeng thought about it, the light on the stone suddenly flashed, and the tiny stone marks raised, and a red square appeared.


    "Seven back to Dan!" Seeing the shape of the elixir, ye Lingfeng''s eyes flashed, and the smile on his face disappeared instantly.


    As the name suggests, this herb needs to be returned to the furnace seven times to become a medicine. Each time it is returned to the furnace, it needs to be re refined with several different kinds of miraculous drugs. In this way, the kinds of miraculous drugs needed to become a pill can be described as very few.


    In this way, there is no doubt that it greatly increases the difficulty for ye Lingfeng to find out the mistakes from Dan Fang.


    "Seven times of going back to Dan is closely related to each other. If it''s a tiny difference, it will be a thousand miles away. It seems that Beiling also thinks that the test of the former two palaces is too simple for this boy, so this time it was qihuidan at the beginning. " Looking over the stone tablet, Liu mingjue joked.


    Bei Qiuzhen also smiles and nods, looking at Ye Lingfeng with interest. At the beginning, when he entered the third palace, it was not until the last ten kinds of pills that he met the complex pills of qihuidan. But this time ye Lingfeng met this very difficult pill at the beginning, which shows the difficulty of this test and the expectation of Beiling to Ye Lingfeng.


    "To return to Dan seven times, you need to add more than ten kinds of elixirs each time. It''s not just that the elixir needed for each return to Dan is closely linked, but the elixir for different return to Dan also needs to be closely linked In this way, we are not analyzing one kind of Dan prescription, but dozens of Dan prescriptions. It''s so difficult. It''s really a good start... "


    After staring at Dan Fang for a long time and imprinting the content in his mind, ye Lingfeng slowly closed his eyes and constantly deliberated on Dan Fang in his mind. Starting from the most subtle changes of vegetation, he found out where the deviation of Dan Fang was.


    After several breath''s deliberation, ye Lingfeng''s eyes suddenly open. At the same time, his hand is extremely fast. He gently strokes toward the stone tablet, erasing the "blue and white grass" in the dense elixir category.


    "So fast!" This move, Bei Qiuzhen can''t help but stare at Ye Lingfeng.


    He just also deliberated in the heart what is the fault of seven return Dan, but at this moment, it is just a little eyebrow. But in such a short time, ye Lingfeng has found out the mistake.


    Not only is Bei Qiuzhen, but Liu mingjue also looks at Ye Lingfeng in disbelief. She just has some eyes at the moment.


    Susu! With the spalling of the stone powder, the onlookers held their breath and wanted to see whether the mistakes Ye Lingfeng found in such a short time were correct.


    Brush! When all the stone powder fell to the ground, the stone tablet flashed, and the next red square appeared quickly.


    "It''s really a lot of blue and white grass!" Bei Qiuzhen was stunned and looked at Ye Lingfeng in disbelief.


    Although he knew that ye Lingfeng''s talent of Dandao was very strong, even more than him, he still didn''t expect that ye Lingfeng could find the mistakes and omissions of this danfang in such a short time.


    What does this fast and accurate result show? It shows that ye Lingfeng has a profound insight into the nature of the elixir.


    Only with such familiarity can we find out the mistakes and omissions of qihuidan in such a short time.


    Brush! But when Bei Qiuzhen sighs, he finds that the stone tablet is shining again. It''s obvious that ye Lingfeng has found out the mistakes and omissions of a piece of Dan Fang in this short video.


    "Incredible Incredible What''s the extent of the boy''s understanding of the medicine? " Bei Qiuzhen sighed with emotion that the development of things had become more and more unexpected.


    He thought that this third Palace should bring some pressure to Ye Lingfeng, but he did not expect that in this case, ye Lingfeng would still go straight up like chopping melons and vegetables.


    Liu mingjue''s eyes are also flashing, and his eyes are also full of incredible colors. She asked herself, even with her Dan Dao attainments, although she could find out the mistakes and omissions of Dan Fang, she was definitely not as fast as ye Lingfeng.


    "The transformation of vegetation is really extensive and profound. If it is not for this skill, which knows the characteristics of the elixir like the palm of the hand, can understand the characteristics of the elixir in the Dan prescription, and find a mistake, the third palace will really take some time."


    Ye Lingfeng''s eyes are shining, and he is constantly deliberating one by one the constantly appearing danfang, feeling in his heart.


    Liu mingjue and Bei Qiuzhen thought that he had made mistakes with the help of herbal medicine, but only he knew it. In fact, he was just as opportunistic as the first one in this stage, using the analysis of the characteristics of herbal medicine.


    Different from other alchemy methods, plants and plants attach the most importance to the characteristics of the elixir. In this way, we don''t need to analyze the characteristics of Lingye at all.


    Boom! Time goes by, an hour later, along the stele suddenly there is a roar, and then, the magnificent light rises, in the bright light, the stele which was blocked in front of us slowly lax."Qian Zhang danfang, it''s a miracle to find out all the mistakes and omissions In such a short time, it''s a miracle that we can do this step... " Seeing that ye Lingfeng has gone to the fourth palace, Bei Qiuzhen sighs.


    As he said, it is a miracle to be able to find out all the mistakes and omissions in such a complex thousand prescriptions. However, it only takes such a little time to achieve all this. This is not a miracle, but an absolute miracle.


    The first three tests are courage, foundation and accumulation. I don''t know what the last test is!


    After taking a deep breath, ye Lingfeng reaches out his hand and pushes open the door of the fourth palace. He wants to see what the test is.


    What''s this? As soon as he stepped into the palace, ye Lingfeng was intoxicated and took a deep breath.


    Boom! Not only Ye Lingfeng, but also the monks who gathered in the square of the trial Monument and paid close attention to Ye Lingfeng through the water mirror. They also kept pumping air, and their eyes were all burning with greed.


    I saw that the fourth palace was not like a palace at all, but more like a huge pharmacy, and it was also an all inclusive pharmacy. Whether it is the most common elixir or the elixir that has disappeared in the world, it all exists.
