Ying Si pondered that his slender fingers brushed over the mechanism, and the spiritual power was instilled, and the orange-red flames slowly rose.

"Three golden flowers, two joint branches, five blue snake grasses, and one nectar flower......"

In the past few days, after more than ten attempts, Ying Si has already been familiar with the steps of refining medicine. Ying Si finished recalling the materials and steps of alchemy, controlling the fire and calming down, he wiped out the Tibetan ring, and three golden patterns and green stamens flew out. Ying Si grasped it, and the spiritual power moved the lid of the Dan furnace and threw the golden flowers into it. Ying Si skillfully controlled the fire, his eyes were fixed on the golden flowers in the Ding furnace, under the scorching orange flames, the golden flowers gradually dried up, oozing out a light green liquid, mixed with a little gold. These are the medicinal essence of Jinbi Flower, but they are still mixed with some impurities, and the liquid needs to be completely purified into gold before it can be counted.

A quarter of an hour later, the essence of the golden sap was finally refined, forming a bright golden liquid the size of an apricot. With a wave of his left hand, Ying Si removed the bright golden liquid from the center of the flame of the Dan Furnace and threw the joint branch into the Dan Furnace. Ying Si concentrated on controlling the flames, and after the bone joint branch was invested, it increased the injection of spiritual power. The texture of the bone joint branch is like white bone, and under the continuous burning of the flames, it can still maintain its original shape, this type of spiritual material can only be refined by water grinding kung fu.

Click, click.

The orange-red flames burned violently under the Dan furnace, and the knuckles were cauterized, and there was a clattering sound, and some of the tiny branches began to fall off and turn into white powder. You should think about the heart method at this time, it is no longer the heart method of the sect of Ling Xiao Pavilion, which controls the nine heavens, but the Purple Mansion Heart Sutra that was exchanged before. Although the cultivation was not completely completed, the intensity of the spiritual power was by no means comparable to what it was before.

The two exercises have their own merits. The Purple Mansion Heart Sutra is different from the Qi Control Nine Heavens, which is to control the Qi with spiritual power and manipulate and refine foreign objects, which is said to be a practice that refers to the Nine Heavens. Qi controls the nine heavens, and among the hundred laws of the immortal gate of the five domains, it ranks eighty-ninth. And the Purple Mansion Heart Sutra, with its grade, generally speaking, can also be ranked in the top fifty. However, what is stronger about it is that through cultivation, Huachi can be gradually transformed and expanded into a space called "Purple Mansion". The Purple Mansion is one of the ascending branches of the "Huachi", which can warm the spiritual artifacts and store and plant spiritual materials. It can be called a blessed land occupied by those immortals, a miniature version of the cave sky.

This time to quench the joint branches, it takes an hour of time, and you should think about constantly instilling spiritual power, and when the joint branches are about to turn into powder, they will intersect with the juice of the yellow ginseng fruit. In this way, the embarrassing situation of turning into ashes before is avoided, and after a pillar of incense is quenched, a silvery-white powder is formed.

[Host, you better take a rest, your spiritual power has been consumed seven or eight times out of ten, and if you forcibly refine the medicine, it will cause great damage to the body's "essence and spirit". ]

Thinking about it in the past few days, he has been refining pills without sleep, and the dark circles under his eyes are now fighting with the national treasure. To be honest, Ying Si didn't want to refine it day and night, but he really couldn't help it, refining a second-order pill to wash the marrow pill by himself, it would take a lot of effort. Look at the protagonists of other novels, every day I practice a pill, build a weapon, practice a skill, and drink water. This can't be endured, although I'm a villain, but, I can't lose it. Not to mention that refining the pill is easy to make, but at least you can't waste too much effort, right?

"No need, people like me are still more suitable for stupid birds to fly first. If you want to rest, you still wait for me to refine this furnace of elixir first. ”

[Feel free to do so, as long as you don't die, I won't care.] ]

After thinking about refusal, he began to continue refining other materials, and from the blue snake grass, several smaller blue crystal crystals were extracted, and this blue crystal, taken alone, has the effect of sewage and descaling. However, there is a high probability that eating alone will cause diarrhea.

What is extracted from the Danyang fruit is a red liquid. This liquid has the effect of sweating and refreshing, and can be used for occasional wind chills.

Of course, in refining the elixir, there are always some strange things. For example, these fluorescent luminous sand obtained from the cave of big-eared bats, this luminous sand has the effect of invigorating blood and removing blood stasis. After some burning, they were refined into tiny gray particles.

There are also some dried earth dragons, which were also bought in the previous store, and have the effect of soothing the meridians. After passing through the Dan furnace, it is burned into a gray powder.

Ying Si looked at these, breathed a sigh of relief, skillfully threw the silver-white powder into the Dan furnace, and continued to burn a stick of incense with medium heat. After that, Ying Sili added the essence of the flowers and the powder of the earth dragon, and they blended together, and under the scorching of the flames, they gradually formed a slimy green paste. Immediately after that, you should think about firing the gray particles made of luminous sand and put them into it.

At this time, Ying Si's mind moved, and he constantly adjusted the temperature of the orange-red flame. He suffered a lot of losses here before, this is a small bottleneck in refining the marrow cleansing pill, after here, the next steps, it will be smooth sailing. Consideration should be given to maintaining the temperature of the green paste on the one hand, and the temperature of the other side of the material on the other. Single-mindedly and diligently, it really took a lot of effort, and wisps of cold sweat gradually appeared on his forehead.

Even if Ying Si had already tried several times, there were still one or two dangers, but fortunately, his eyes were quick and he was in danger. After that, Ying Sili added the juice of the Danyang fruit to the Dan furnace, and after the quenching of the flame, a round prototype of the Dan medicine had been produced. Ying Si saw this, his heart was slightly happy, he knew that the pill had been refined eight or nine times out of ten.

With a wave of his hand, the crystals of the Blue Snake Grass were thrown into the Dan Furnace, turning into a layer of light blue energy cover, enveloping the rudiments of the Dan. Immediately after, Ying Si manipulated the flames, forming a long snake, and swallowed the rudimentary form of the elixir in one gulp. The blazing orange-red flame erupted, and then condensed down, pressing the abundant medicinal power into the elixir. A moment later, the flames were extinguished, and three milky white pills appeared in the Dan furnace, emitting a white light, which was beautiful.

Seeing the success of the refining of the pill, Ying Si was slightly happy in his heart, and with a move of his palm, several pills flew into his hand. Immediately after, Ying Si took out a white jade bottle from the Tibetan ring and filled it with the elixir. And the orange-red flame of the Dan furnace, because of the withdrawal of spiritual power, gradually faded until it was extinguished. The original reddish furnace gradually returned to its original color, as if nothing had happened.

Ying Si thought that his forehead was full of beads of sweat, and the young man's face was even paler, he had not rested for three days and three nights, and the reason why he persevered until now was still a gamble. The spiritual power is the combination of the monk's spirit, energy, and spirit, and he has consumed a lot of thoughts in the past three days and three nights, and even his body has lost a lot of weight. However, the results are still obvious, after two days and one night of failed attempts, Ying Si has refined a total of eight furnaces of marrow washing pills and three furnaces of bone cutting pills. Among them, there are only three furnaces with a relatively high-quality color of the marrow washing pill, and only one furnace is more high-grade from the bone cutting pill. The Danfang that should be considered is not the popular Danfang in the Dan Palace, there are three in one furnace of his marrow washing pill, and four in one furnace of bone cutting pill.

After Ying Si put the white jade bottle into the Tibetan ring, it was as if all his strength had been drained, and his figure, which he had worked so hard to maintain, collapsed on his back, and breathed in a big gulp of air, like a fish that had left the water. His solid chest continued to rise and fall, his body could no longer feel a trace of strength, and his whole body was sore, as if there were countless ants gnawing at his bones, as long as he moved slightly, he would pull his whole body. Now, he was lying on the ground like mud, and the only thought in his mind was to get some rest, and wake up with a feast. But alas, you should consider whether it is a villain or a villain who may become an experience pack at any time. He definitely can't tolerate wasting his time, especially when the protagonist he may face in the future keeps hanging up.

Ying Si gritted his teeth fiercely, endured the violent soreness and sleepiness, and with a touch of his fingers on the Tibetan ring, the light flickered, and a bottle of Bone Cutting Pill appeared in his hand. He uncorked the bottle, and a pungent smell of medicine came out, which lifted his spirits slightly. This is the most outstanding furnace of Bone Cutting Pill that should be considered, and the color is even better, he took out two light cyan Bone Cutting Pills and swallowed them in one gulp. The Bone Cutting Pill fell into the belly, and after a while, the cyan energy turned into the medicinal power rushed up from the lower abdomen.

"Ahh

Ying Si screamed in pain, he had also taken a bone cutting pill before, and the medicinal power was not so strong? The cyan medicinal power was constantly shuttling along his bones one by one, and this feeling that brought Ying Si Li was like a small steel hammer beating every bone, every inch of bone. This pain was ten times that of the previous Bone Cutting Pill, and it was no less than the feeling of piercing the bone marrow with a steel needle.

At this time, you should think about sweating, if the cold sweat that overdrew the spiritual power before was raindrops, then the cold sweat now is simply a river. His teeth kept rubbing against his mouth, making a clicking sound, and a few words popped out from between his teeth: "This, in the end, in fact, yes, how, what, back, what?"

[That's right, the Danfang obtained by the host here in the system belongs to the long history, and the demon monk who has long been lost has created it.] They have a characteristic, that is, they have high yield and high medicinal efficacy, and they are a must-have pill for demon monks to travel at home. However, there are gains and losses, and compared to other pills, it is more difficult to refine. The most important thing is that after taking it, it will break out with ordinary pills, twice as many side effects. The side effect of vasteoedan is severe pain. ]

"System, but how do I feel when I step on the horse, the pain caused by the two Bone Cutting Pills I took this time doesn't look like it's only twice as much?" Ying Si's eyes were bloodshot, and the originally abyss-like pupils were stretched out very much because of the severe pain at this time, and the upper teeth bit their lips, and bright red blood flowed out.

[Maybe it's because the host ate two pills in a row and the sore spot turned over?] Now, the host may be ten times more painful.] The system replied solemnly.

"Two-two-ten-system, your math is taught by a physical education teacher, right?"
