Late at night, inside the cat house.

  "General, that Extreme Realm Pill makes me feel so weird!"

  Su Qiluo sat on Duke's cat kennel, holding Xiao Ha Thirteen in his arms, and Su Qiluo was scratching Xiao Ha's stomach.

  Xiao Ha, who was facing the sky on his back, lay on his back in Su Qiluo's arms, because his stomach was tickled by Su Qiluo, his calves were also shaking, and his dog face was even more smiling.

  "What's weird?"

  Duke took a pen and wrote a line of words, and Su Qiluo also paused the action of scratching Xiao Ha's stomach, recalling the process of refining his body after taking the pill.

  "It's like wearing a fishing net on your body, not to mention that your skin and flesh are shackled, but in the process of deepening and refining, your skin and flesh are squeezed."

  Speaking of this, Su Qiluo also shuddered.

  "It hurts!"

  Duke stopped writing when he heard Su Qiluo say this, although Su Qiluo was pampered, but he was not a princess disease, and he was not squeamish.

  When the Extreme Realm Pill was effective, the pain it produced made Su Qiluo say this, and it was really painful to think about it.

  "Hundreds of tempered into steel, boil it and it will pass."

  Duke took a pen and wrote down a line of words to comfort Su Qiluo, and Su Qiluo nodded vigorously, "I know, only by suffering hardship can you become a master!"

  As soon as Sukiro said this, Duke smiled helplessly, this girl was already in Rome as soon as she was born.

  To say this sentence again is really not to give others a way to live.

  The rich second generation is not terrible, the terrible thing is that the rich second generation works harder than you, Duke really understands this sentence.

  "I told Aunt Yun about the Extreme Realm Pill, and Aunt Yun will find a way to help the general intercept some of it."

  Su Qiluo looked like he was inviting credit, and when Duke saw this, he didn't hesitate to praise him.

  "It's still my girl who is the best for me."

  Seeing this, Su Qiluo's eyes suddenly narrowed with laughter.

  "However, the Extreme Realm Pill needs the Skin and Flesh Realm Dacheng to take it, General, you have to cultivate well and advance to the Skin and Flesh Realm Dacheng as soon as possible!"

  Su Qiongluo didn't forget the point that Yun Yi had told her, and Duke nodded suddenly, "I have my own arrangements, you don't need to worry."

  "Just give me the pill to prepare."

  "Okay, I'll prepare the pill for you, General."

  Su Qiluo nodded vigorously, and Duke also continued: "At this stage, what we have to do is to continue to improve our strength and become stronger.

  "I know."

  "It's good that you know, it's not early, let's go to bed early."

  When Duke wrote this, he also put down the brush in his hand, and when Su Qiluo saw this, he put down Xiao Ha in his arms.

  "Then I'll go to sleep, general, you should rest early."

  Duke nodded silently and watched Sukiro leave.

  After the girl left, Duke threw the rice paper she had just written on into the black space, and turned her head to see Xiao Ha squatting in front of her.

  Looking at this little husky, Duke tilted his head, what do you want to do?

  Xiao Ha Thirteen tilted his body, and while lying on the ground, he also exposed his belly, whined twice, and motioned for Duke to scratch his stomach.

  This stupid dog!

  The corners of Duke's mouth twitched slightly, and he slapped it into a rolling gourd with one paw.

  Let's play!

  Xiao Ha, who rolled all the way back to his kennel, turned over and sat up, his eyes squeezed into cross-eyed, and at the same time, he shook his head, and then fell into his kennel.

  After settling Xiao Ha, Duke also jumped onto the platform where he practiced on weekdays, looking at the blood and qi pill in the wooden box.

  For these elixirs, he had a bold idea.

  And this bold idea was born because he had a basic understanding of the Dan Dao of this world after he had refined all the Dan books that Zhao Danshi had obtained and had been refined into Shu Dan and swallowed them.

  Before I talk about this idea, let's talk about the Dan Dao of this world.

  The book of Dan points out: If you want to make alchemy, you must first understand the medicinal properties of medicinal materials, medicinal materials are like beauties, different medicinal materials have their own temper and ability, and it generally takes ordinary people to understand the medicinal properties It takes ordinary people to take three to five years.

  However, for Duke, it is also a matter of medical books related to refining and chemistry.

  Secondly, there is the problem of collocation between various medicinal materials.

  Within the Dan Dao, it is called the monarch and the minister auxiliary demon.

  If it is simply said, it corresponds to the five fingers of the human palm.

  Among the five fingers, the thumb has the greatest role and is in the position of the king, while the index finger, middle finger and little finger are listed as ministers, auxiliaries and assistants respectively.

  As for the demon at the end, it's the little thumb.

  Because the little thumb is useless, the demon is also useless in alchemy.

  In alchemy, it is necessary to consider the four auxiliary of the monarch and the minister, the main medicine is the king, the secondary medicine is the minister, the second is the auxiliary, and the last medicine is the adjuvant.

  The story has been taken without consent; if you see it on Amazon, report the incident.

  The combination of the four can refine the best elixir.

  As for the last demon, it is not mentioned in detail in the Dan book, but it is just a mouthful, and the left Taoist is mainly demonic.

  When the alchemy apprentice understands the medicinal properties and understands the truth of the monarch and the minister assisting the demon, he can start to learn the pill formula.

  As the saying goes, it is difficult for a good woman to cook without rice.

  Without Danfang, no matter how powerful an alchemist is, he is a fool who goes to the battlefield with a gun and no bullets.

  In addition to the above three points, the most important thing in the Dan Dao is refining. In the process of alchemy, the alchemist needs to consider the situation of the Dan furnace, the heat of the alchemy, the combination of medicinal materials, and even the weather have an impact on the Dan.

  Moreover, after the elixir is refined, the medicinal properties are even more important.

  After all, it is a medicine with three points of poison, even if it is an elixir to improve cultivation, it is also a little toxic.

  This poison is collectively known as erysipelas.

  Cultivators who take pills for a long time will accumulate erysipelas in their bodies, and erysipelas is only bad for cultivation and not beneficial.

  Therefore, the medicinal properties of the elixir are the most important means to test an alchemist.

  Three points of medicine are the last, six points are medium, eight points are superior, and eight and a half to nine points are the grandmaster.

  As for the medicinal properties, there is only one sentence recorded in the Dan book, and no one can reach it.

  Dan Dao four points, for Duke, it is precisely the first three points that are important.

  As for the last and most important point, it is not so important to Duke.

  After all, he has the Black Ding.

  Heiding can even refine moonlight into Dan, let alone others.

  As for the medicinal properties of the elixir he refined in Heiding, Duke estimated that it should be ten, because he had not noticed the existence of the so-called erysipelas from the beginning to the present.

  And after reading these theories, Duke also gave birth to a novel and bold idea in his heart.

  Ordinary pills have erysipelas because of the alchemist, so if you refine the pills of other alchemists through Heiding for the second time, will the erysipelas still exist?

  How strong will the efficacy of the drug be?

  The pills he eats at this stage are all pills refined by other Dan masters.

  Duke's dependence on these pills is not strong, after all, kryptonite becomes stronger, and there are only zero and countless times.

  Duke, who is already accustomed to drug cultivation, if you ask him to honestly go back and rely on his own efforts, it is simply impossible.

  And there is erysipelas in the pills, and in the past period of time, he swallowed not a thousand, but hundreds.

  As the saying goes, a small amount adds up to a lot, the water drops and stones wear, and the rope saws the wood.

  So much erysipelas accumulated in his body was a problem he had to consider.

  Therefore, he had to find a way to find a way to reprocess other people's pills.

  Therefore, the idea of refining the pill for the second time was born.

  "Try it!"

  Duke, who has a strong sense of action, immediately included all the Blood Qi Pills in his Black Ding space.

  In the Black Ding space, dozens of soybean-sized pills appeared at the same time, Duke let out a low sigh in his heart.

  "Lian!!"

  In the next second,

  several pills were thrown into the black tripod at the same time, and the flames in the tripod jumped up violently, devouring the pill while also fusing the blood qi pill into a ball of liquid medicine.

  While the liquid medicine was agitated in the flames, wisps of black smoke rose from the flames.

  These are black smoke that forms when impurities are burned.

  When the impurities were removed, the liquid medicine was closed to each other, and it was quickly pinched into a ball by the flames, turning into a blood-red pill the size of a grain of rice.

  Not long after, Hei Ding was shocked, and the blood-red pill flew out of it and was embedded in the void.

  "That's it?"

  Duke stared at the pill the size of a grain of rice and couldn't help but blink.

  "Try it!"

  As soon as he thought of this, the pill the size of a grain of rice was taken out of the Black Ding Space by Duke and swallowed into his stomach.

  Then,

  boom!!

  Duke's mouth was wide open, and his eyes were also round, this medicine was more than ten times stronger than before, and a cloud of rich, fiery medicinal power exploded in his body almost instantly.

  "Damn, this method really works, but this potent effect is too exaggerated!"

  While Duke was secretly scolding in his heart, he also quickly put on a posture and began to mobilize qi and blood and absorb the power of medicine.

  The berserk power swept through Duke's body, causing a little blood to ooze from his fur, and the blood soaked outward along his hair, quickly dyeing his dustless hair into a blood-red clump.

  At the same time, in the cat house, there is a hidden beast roar echoing, although immature, it has already shown its grandeur.
