When it comes to alchemy, the control of fire is very important. Generally speaking, it can be divided into slow fire and vigorous fire. Once the heat is not properly controlled, the quality of the elixir may deteriorate, or the elixir cauldron may explode. The jade cauldron buzzed and trembled, and Yu Ming could not take his eyes away. After a quarter of an hour, misty white steam slowly rose from the cauldron. Yu Ming accurately grasped the opportunity, and immediately, with quick eyes and quick hands, poured the prepared seabass liver into the jade cauldron. . Hearing a crisp sound, a ball of blood rose up from the jade cauldron. Yu Hao opened his pupils wide and looked inside the jade tripod. The next moment, my eyes lit up. "Blood-Building Pill, successful." Yu Hao looked at the Blood-Building Pill lying quietly at the bottom of the jade cauldron, and couldn't help but raise the corner of his mouth. This blood-tonifying pill is about the size of a fingernail, slightly red, and exudes rich blood energy. "Refining blood-tonifying pills is very particular. First of all, the selection of medicinal materials is extremely strict. Secondly, the heat cannot be sloppy. The bass liver must be poured into the jade cauldron at the moment when the white steam rises, and then the bass liver can be locked. The internal medicinal power will not work even if it is one minute earlier or one minute later." Yu Ming smiled slightly, "After a period of training, my success rate in refining the blood-tonifying pill is now over 50%. However, this is still far from it! It¡¯s not enough. It¡¯s still far from being able to refine a second-grade elixir.¡± Shaking his head, Yu Ming stretched out his hand to twist the blood-tonifying elixir, put it on the tip of his nose and smelled it, and then continued to concentrate on refining the elixir with satisfaction Peng! About a quarter of an hour later, the jade tripod suddenly trembled, and thick black smoke billowed out. "Oops, failed!" Gritting his teeth, Yu Ming breathed out a breath with difficulty. He immediately kept moving and legs, adjusted his condition again, and began to continue refining the elixir. Right now, Yu Ming wants to improve his condition to its peak as soon as possible, and then attack the second-grade elixir. Otherwise, onerous debts will never be paid off. The deadline of half a month was like a sharp knife hanging on his neck, making Yu Ming unable to breathe. In the blink of an eye, the sky has darkened, the shadows of the trees are swaying back and forth outside the window, the birds are returning to their nests one after another, and the cold is getting heavier and heavier. In the house, Yu Ming lit an oil lamp and kept refining the elixir as if he was crazy. Ding! There was only a crisp sound, and a strong medicinal fragrance hit your mouth and nose. "Successful." Yu Ming smiled slightly. Ding! Ding! Three times in a row, Yu Ming successfully refined the Blood Replenishing Pill, which further improved the success rate. Finally, Yu Ming, who had been moving non-stop, stopped, his face as red as a red-hot iron. "Haha, I have succeeded in refining elixirs three times in a row. My current state has reached its best. It is the perfect time to attack the second-grade elixir." Yu Ming raised the corner of his mouth and immediately took out one from the sack on the side. Senbai's tiger bones, as well as caltrop, bezoar, snow lotus leaves these are the main medicinal materials for refining the second-grade tiger bone pill. The second-grade Tiger Bone Pill can strengthen the bones and nourish the internal organs. It is a rare panacea. It is a very important supplement for warriors who are new to the martial arts realm. If Yu Ming can successfully refine the second-grade Tiger Bone Pill, the huge profit will not be comparable to that of the first-grade Blood Replenishing Pill. "The cauldron fire, start." Yu Ming stretched out his hand and patted it, and the natal jade cauldron immediately buzzed and vibrated. Yu Ming concentrated on it and did not dare to be careless. On the table in front of him, tiger bones, caltrops, bezoars, snow lotus leaves and other medicinal materials were neatly placed. Suddenly, Yu Ming flipped his hand and threw the water chestnut and bezoar into the jade cauldron. A series of sounds were heard, and the water chestnuts and bezoars were gradually boiled into a thin layer of thick juice, which sank to the bottom of the alchemy cauldron. "Tiger bones, come here." Yu Ming observed the situation of the cauldron fire, picked the right moment, stretched out his hand, and threw the tiger bones into the alchemy cauldron. Immediately, the natal jade cauldron began to tremble, and a series of reactions took place in the thick juice and tiger bones inside the alchemy cauldron. "It must succeed." Yu Ming licked his chapped lips and prayed secretly. Finally, the Benming Jade Cauldron gradually stopped trembling. The thick juice in the alchemy cauldron had been completely absorbed by the tiger bones, and the tiger bones were condensed into a pill the size of a fingernail. Looking at the fiery red pills at the bottom of the pill cauldron, Yu Ming felt uneasy and hurriedly reached out and put the last medicine into the pill cauldron. "Snow lotus leaf." Yu Ming reached out and threw it, and the snow lotus leaf was thrown into the inside of the alchemy cauldron. Refining alchemy pays attention to the balance of yin and yang. Tiger bone is yang in nature and needs to be reconciled with yin and cold things. Snow lotus leaf is the most critical medicinal material used to temper the fire. Peng! ??????????????????????????????????????????????????????????????????????????????????????????????????????????????????? With a loud sound, the jade tripod of life trembled violently, and a stream of acrid black smoke arose, and the whole room was filled with filth. "Oops, failed" Looking at the scene in front of him, Yu Ming couldn't help but sigh and fell to the ground slumped. The continuous alchemy making has made Yu Ming very tired. Now, his nerves were tense again, and the impact of the second-grade Tiger Bone Pill greatly consumed Yu Ming's mental energy. Looking at the fine powder of the medicine in the cauldron, Yu Ming felt very regretful as he was exhausted. "I'm so tired. I have to recover as soon as possible." Yu Ming sat up with support, took out a blood-replenishing pill from his arms, and swallowed it in his mouth. He immediately began to sit cross-legged, absorbing the power of the medicine, and tried his best to restore his condition. The night was getting darker, and the entire Qiyun Castle was completely silent except for the occasional crow call. Suddenly, on the bluestone road under the moonlight, a thin figure was walking quickly towards Yu Ming's house, carrying a food box in his hand, and his pretty face was covered with beads of sweat as big as peas. Hongfu spent the whole day seeking medical advice for Niu Hao. When he returned to his residence, it was already late at night. He had worked hard all day and had no time to rest. He suddenly remembered that Yu Ming had not eaten dinner yet, so he hurriedly made some snacks overnight. , sent to Yu Ming. "It's late at night. I wonder if the young master is asleep?" Hongfu murmured to himself, feeling a little more self-blame in his heart. Arriving at the door, Hong Fu stopped and stood, looking into the house through the crack in the door in surprise. Under the dim light, Yu Ming was clearly refining elixirs. One person and one cauldron were still busy. The ground was covered with various herbs Hong Fu was startled, and he was stunned for a long time before he looked back in despair. After coming to his senses, he didn't dare to disturb Yu Ming. He just quietly placed the food box in front of the door. Then he listened secretly for a while, then sighed and left quickly. The next day, Hongfu delivered the food on time. Desserts are obviously much richer than before. The next ten days and ten nights will be non-stop! Yu Ming has not had a peaceful sleep for ten days and ten nights in a row. Both physically and mentally, he is on the verge of collapse. Physically, Yu Ming is as strong as an ox, and with blood-tonifying pills and sumptuous dishes, he can barely hold on. But the mental torture made Yu Ming very tortured. Today's Yu Ming is like a tight bowstring. Once loosened, it can no longer be tightened. Therefore, Yu Ming gritted his teeth, gritted his bones, and fought to the death to support him! ¡°Poof!¡± The jade cauldron shook, and puffs of black smoke filled the room. "Poof!" The jade tripod shook, and wisps of thick smoke slowly drifted out of the window. "Pfft!" "Pfft!" "Pfft" Yu Ming didn't know how many times he failed. He just felt like he was possessed, frantically improving his alchemy experience. This night, the bright moon was in the sky, and the faint silver light shone through the half-open window into the house, making the smoky room clear. "Snow lotus leaves." Yu Ming's eyes were bleeding, and he stared at the jade cauldron of his destiny. Suddenly, he stretched out his hand and threw the snow lotus leaves into the jade cauldron. Immediately afterwards, my whole body tensed up and I looked at the jade tripod anxiously Ding! After a while, the life jade tripod shook a few times, and finally stopped slowly, and wisps of medicinal fragrance overflowed out. "What, I succeeded?" Yu Ming's eyes lit up and he rushed forward in a hurry, staring at the jade tripod! In the jade cauldron, a fiery red tiger bone pill lay quietly, exuding an alluring medicinal fragrance "Haha, I finally succeeded! I refined this second-grade tiger bone pill. My alchemy skills, It¡¯s a step up!¡± At this moment, Yu Ming was almost ecstatic and dancing! After ten days and ten nights of almost sleepless elixir refining, finally at this moment, after all the hardships, I successfully refined a second-grade tiger bone elixir! This second-grade tiger bone elixir is the best among second-grade elixirs. It can nourish the internal organs and strengthen the bones. It is an indispensable panacea for warriors at the second and third levels of the martial arts realm! It can be said that the profit gained from selling just this Tiger Bone Pill is equivalent to the profit from twenty or thirty Blood Replenishing Pills! "This Tiger Bone Pill is a second-grade elixir. If I can refine more Tiger Bone Pills in the remaining five days, I will be able to collect enough silver to repay the debt. I am very confident." Yu Ming played with a fiery red tiger bone pill on his fingertips, feeling extremely happy. The emotions that had been suppressed for more than ten days were finally released perfectly at this moment! After taking a short rest, Yu Ming immediately stood up again and began to prepare medicinal materials such as water chestnuts, snow lotus leaves, bezoar, and tiger bones to continue refining the tiger bone pill. Now, Yu Ming's alchemy skills have undergone a dramatic transformation, and it is a good time to strike while the iron is hot. Five days later, it will be the deadline. At that time, Mo Ziqiao will bring people to demand the debt. Yu Ming must collect enough silver as soon as possible no matter what. "Fire, start." Yu Ming shouted low and used all his strength to activate the jade cauldron. Unexpectedly, the jade cauldron shook slightly, and the fire in the cauldron quickly went out. "What, my natal jade cauldron can't support it anymore?" Feeling the dire condition of his natal jade cauldron, Yu Ming's expression suddenly changed. He never expected that after more than ten days of sleepless elixir refining, he could actually The Jade Cauldron of Obtained Life has been damaged to the point where it is almost unsustainable! As the saying goes, a good woman cannot make a meal without rice. If Yu Ming loses his life jade tripod, he may never be able to recover! "No, I have persisted for ten days and ten nights, and I will never give up easily!" "Fire, start!" Yu Ming gritted his steel teeth, with blood in his eyes, and activated the fire in the jade cauldron again. Who would have thought that at this moment, Yu Ming's body swayed, and the fatigue accumulated over the past ten days suddenly surged into his heart, causing Yu Ming to scream miserably, opening his mouth to spurt out gurgling blood, and collapsed to the ground. With a loud bang, the table turned over, and all kinds of medicinal materials and jade tripods fell to the ground, stained scarlet with blood! ?¡ ?¡ ?¡
