"Spring and Autumn Wood was born on the only mountain peak connected to Kun Miao Prefecture and Gen Yuan Prefecture, Tianque Mountain, because of the particularity of the geographical location, when Kun Miao Prefecture is in spring, Gen Yuan Prefecture is autumn, so Spring and Autumn Wood is also called Yin and Yang Wood. Half spring wood, half autumn wood. It is the body of the lightning strike wood, and only the trees that have lived there for more than a hundred years can become lightning strike wood after being broken by the Nine Heavenly Thunder. Its nature is warm and bitter in taste, and it is mostly used in women's pills. ”

"Heavenly Phoenix Leaf!"

The second girl's expression has changed dramatically, the grass and trees that Chu Rui came out of are in the front position of Wan Mu, the grass and trees that Bi Xuan said are just the opposite, and Yu Si actually recited it well.

This day phoenix leaves are extremely rare, it is a plant and tree in ancient times, and now it is almost extinct, and it is included in the side story. The plants and trees that belong to the outside of ten thousand trees are generally just piggybacking on them.

"Heavenly phoenix leaves, legend has it that after the powerful monk of the Wind Clan turned into a snake, when he molted his skin, a leaf flew down and covered the snake skin, which was impregnated by sperm and aura, and had aura and spiritual sense. There is no way to verify the sexual taste and attributes, and Wan Muzhong only says that it is a thing that enhances divine consciousness. ”

"Youkai—"

The second daughter no longer asked questions, covered her mouth, and ran away.

"Come back, come back. Teach this monster alchemy tomorrow!" Yu Si chased a few steps and shouted loudly.

On the second day, the second daughter fulfilled the agreement and explained to Yu Si how to make alchemy: first, there are enough Dan materials, second, there is a strong Dan furnace, third, there is a controllable fire source, fourth, there is the correct means of application, and fifth, there is enough spiritual power.

These are the conditions that alchemy should have, and it is necessary to avoid the problems that are often encountered by Dan masters, such as violent furnaces, fried pills, and lack of fire, and deal with the state of the Dan materials that need to be put into the furnace. There are so many things to ask for.

"Fifth Senior Sister, Dan Furnace and Dan Fang are settled by you. Ninth Senior Sister, Dancai and Danhuo are yours to solve. When it is ready, we will refine the pill. ”

"You-"

"Once you say it——, admit that you will lose the bet!" Yu Si put his hands behind his back, shook his head, and pointed out.

"Hmph, let's go. Soon, the second daughter brought what she needed. These things are extremely simple for them, like searching for things, and they are inseparable from them almost every day. Bi Xuan pouted.

"Where are you going?"

"Idiot! ”

The three of them came to the majestic and magnificent hall that Yu Si had been to before, and entered the underground where the magma was tumbling, and Chu Rui opened an independent stone room. The second daughter then took out the Dan furnace and other things needed for alchemy.

"The Dan material is processed according to the requirements of the Dan Fang, and then the Dan furnace is placed in the ground fire to warm the furnace, according to the long-term use of the induction, the number burned on the Dan furnace is the position where it is placed in the ground fire, the depth of the ground fire is different, and the temperature is not the same. How much temperature is needed, the height of the Dan furnace is moved, and the temperature of each layer has a corresponding mechanism to fix the Dan furnace. Then step by step, the processed Dan materials are thrown into it, stirred one by one according to the refining process, and gradually heated. The plants and trees in the furnace can blend with each other and then condense into Dan. You first feel the Danfang. ”

Chu Rui explained in detail, in fact, she got Gu Yi's clear instructions, that is, to teach Yu Si the corresponding knowledge of alchemy, so that he could refine the pill independently, but she didn't imagine that Yu Si would have to refine the pill by herself so quickly.

Gu Yuan Dan, this pill is used by the monks of the Great Perfection in the late stage of the Dao Foundation when the impact of the embryonic stage is unsuccessful, in order to prevent the inertial fall of cultivation, this pill can offset the riot spiritual power on the monk's soul and cultivation above the backlash.

Ten thousand years of two heads of ginseng and one finger, four layers of fire into the furnace half incense. For thousands of years, the three pieces of Tianlian have been connected, and the five layers of fire have been put into the furnace. The hundred-year-old Tongyu branch is peeled off, and the twelve layers of fire are put into the furnace for twelve hours. Three hundred years of Hantan liquid seven jars of raw liquid, each melted material put a jar. Ten Thousand Year Green Spirit Beast Demon Pill Nine net cores, remove fishy glands, eighteen layers of fire into the furnace for twenty-four hours.

"Don't need to observe?" Chu Rui asked in disbelief as he looked at Yu Si's hands-on posture.

"Didn't you say that I should refine the pill?"

Yu Si said while dealing with Dancai. Taking into account the Dan furnace, the upper and lower heights are adjusted accordingly, and then the Dan materials are thrown into the Dan furnace one by one, and the time of the fusion of the Dan materials in the furnace is measured with an hourglass, and the temperature of the Dan furnace is increased and decreased by measuring the fire temperature.

Second daughter, look at me, let me look at you, I was actually shocked by Yu Si's accurate every step of the first alchemy, and they also had the first time, but they were all in a hurry.

In this way, two days passed, and Yu Si was refining this furnace of elixir step by step.

"Boom!" There was a loud bang in the medicine furnace, and the sound wave that shook the entire Danfeng was so true that almost all the monks could hear it clearly.

"It's hot. "It's almost an impeccable every step, but in the end, the heat of the Dan furnace was not grasped, and the success was successful. Chu Rui nodded.

Yu Si was not discouraged, and immediately cleaned up the Dan materials in the medicine furnace that were not completely fused, and these Dan materials were charred and black, and they looked like they were wasted.

Refining the pill repeatedly, and once again it was time to finally melt the pill, Yu Si carefully grasped the temperature of the pill furnace.

"Bang!" sounded like the furnace that destroyed the pill three days ago, and a huge sound wave sounded.

Yu Si looked at the remains of a furnace of Dancai blankly, and he was really speechless.

Seven days later, a pungent and strong smell wafted over all areas of Danfeng.

At this moment, Yu Si Shi is more casual, these pill materials, including the dosage and the corresponding need for fire, seem to have already been integrated into his sea of knowledge, and he doesn't need to think about it, he will naturally refine it according to his requirements.

After a stick of incense, wisps of medicinal fragrance overflowed from the Dan furnace.

Half an hour later, a brown mist began to form on the top of the Dan furnace.

Chu Rui and Bi Xuan have been staring at every step of Yu Si's alchemy, carefully observing whether he has missed anything and whether there is a mistake. Even so, I didn't find any opportunity to interject, because Yu Si seemed to be a seasoned Dan master, and the two of them only had to figure it out.

After an hour, the fire of the Dan furnace gradually went out, and the churning furnace began to subside as the temperature dropped.

Yu Si let out a sigh of relief, looked at the second daughter who was concentrated, and said, "Is it the junior brother who is here to remove the lid of the furnace, or the two senior sisters who are here to remove the lid of the furnace?"

The two girls didn't say anything, they approached the Dan furnace on the left and right, and each pointed out a finger tacitly, and the two lights gently lifted the lid of the furnace. Suddenly, a rich and strong medicinal fragrance came to the nostrils, and the reddish-brown round pill appeared in the Dan furnace. The second daughter was surprised and inexplicable, and at the same time, regardless of the existence of hot residual temperature on it, she immediately took it close to her and held it in her hand, feeling round and smooth.

While the second girl was dumbfounded, she carefully counted the two back and forth, there were actually seven pieces of this round object, and there were as many as five Dan patterns on it.

"Demon!" Bi declared, turning around and running out of the stone chamber.

Then Chu Rui looked at Yu Si, who was standing still, and also ran out with the round pill refined by Yu Si in his hand.

"Did it work out or not? ”

Yu Si also left the stone room stupidly. In the underground Dangu, looking at the ground of the hall that was thousands of feet high, there was no way. The Fifth Senior Sister and the Ninth Senior Sister can fly directly if they have cultivation, but they can't fly yet, not even the Imperial Sword or the Imperial Object.

"Master, this is the elixir refined by the tenth junior brother, and there are actually five pill patterns, and the ninth senior sister and I can confirm that he is refining the pill for the first time. The disciples have been in the beginner for twenty years, and they can't refine the five-grade spirit pill, the ten junior disciples are really geniuses, these pill disciples need to rush through the level, you see ....... Chu Rui handed the elixir refined to Gu Yi and said.

"Master, Lao Shi is a demon, and Wan Mu knows all of them in just one day. In the refining of this high-grade elixir, he almost didn't let me and the fifth senior sister interfere. Give this Gu Yuan Dan to the apprentice, and the apprentice may need it in a few days. Bi Xuan clenched the pill that was refined.

"It's no problem for you two, but you two have to do something for the teacher. ”

When Gu Yi saw the elixir in the hands of the second daughter, he was very happy in his heart, at first he thought that it was refined by the second daughter or other old disciples. Previously, including Senior Brother Qiao Liang, all the disciples who were still in the peak had refined the Four-Rank Spirit Pill at most. Hearing the second daughter's story, Fang knew that it was Yu Si who did it, and couldn't help but have another thought, and said: "You two are so ......."

"Senior sister, you all ran away and left me here alone, is this okay?" Looking at the second daughter who flew down from the Dan Palace, Yu Si asked aggrievedly.

"If you want to go out, we've been standing with you for ten days, right? Leave after refining. Bi Xuan was undoubted, grabbed Yu Si's neckline, pinched his ear, and walked to the deeper stone chamber of Dangu.

"Sister, spare your life, junior brother will leave by himself!" Bi Xuan and Yu Si are only three years old, and Yu Si's height is more than an inch taller than Bi Xuan. This pull made Yu Si almost unable to straighten his waist, and half-curled up behind the second daughter, looking very funny.

Pulling apart the stone room, which was hotter than before, the second daughter arranged an enchantment for Yu Si, isolated the hot roasting, and took out a large pile of Dan materials. After sensing the pill recipe on the jade slip, he deliberately left the jade slip near the si, and began to apply the specific alchemy steps.

Three days later, a loud "boom!" rang out in a stone room.

Bi Xuan said to himself: "Every step is done according to the requirements of the Dan Fang, but why is this happening? Although Xuan Yan participates in the medicinal properties of Bi Ting Xiang, I have already added enough Qianli Fang to blend it, why do I still fry the furnace?"

"Senior sister is here!" This time Chu Rui personally refined it, and started it one by one from scratch.

"Bang!" The result was the same, three days later, Chu Rui's Dan was also scrapped.

Yu Si had already secretly sensed the Dan Fang, out of respect for the second daughter, he didn't point fingers, and couldn't help but say at this time: "Xuan Yan's participation in Bi Tingxiang was originally a fire attribute, and the other was a thing of the Yin. Senior Sister used Qianli Fang to forcibly blend the two Dan materials that were the same as water and fire, not only the chance of becoming a Dan was extremely slim, even if it was refined into a pill, it was also a low-grade Fan Dan, it was better to replace this Xuanyan ginseng with a moon vine fruit. ”

"Moon vine fruit?" Chu Rui pondered for a long time and said, "This Dan effect is much weaker, right?"

Yu Si explained: "How is it possible, the moon vine fruit is originally of the same family as Bitingxiang, and it has the effect of embryonic transformation, and the result is bound to be more prominent than Xuanyan ginseng. When it is paired with Qianlifang, Qianlifang is not an auxiliary material, so that the medicinal power of these two main materials can be doubled at the same time, and it can exert its own medicinal properties, and it will definitely be several layers higher than the Dan power refined by the original Xuanyan ginseng. ”

"Do you see this is Dodiran's Dan Fang?"
