Geng Di left three bottles of solid pills, which was more than enough to satisfy Lin Yunyue's cultivation for a long time.

Lin Yun looked at the pill in his hand, and felt a little emotion in his heart, how many people think that it will take a lot of hardships to get one, but he has it at his fingertips.

If he didn't have a strange experience at the beginning, he would have been struggling to accumulate military merits somewhere at this time.

Although I don't know where the tiger shape in my consciousness comes from, it must not be a bad thing.

"Tiger and Leopard Thunder Sound" forging bones, for Lin Yun, he can consume a solid pill in one day, and he has never thought about replacing the pill with military merit.

Normally, it takes five to seven days for ordinary qi and blood martial artists to refine the solid pill effect in their bodies, only with the more bones refined, the faster the refining pill will be, and it can even be refined in two to three days in the later stage of bone refining.

The prohibition at the entrance of the cave requires holding this token to enter and exit, Lin Yun can't wait to try the effect of this spirit gathering array at this moment, the stronger the power of qi and blood, the faster the speed of bone refining, until the bone refining is completed, the qi and blood burst out, forming wolf smoke.

The Blood Spirit Stone, with the powerful power of qi and blood, resists the refining of the earth fire, and it takes several hours to condense into the blood spirit essence, and it takes several hours to condense into the blood spirit essence, and in the comprehensive medicinal properties of the ice rain grass, with the petals of the three-eyed flower, in addition to the spiritual materials such as yellow essence and Xingquan leaves, it is refined by the earth fire to become the blood spirit pill.

Among them, the most important is the blood spirit essence, the purer the condensed blood spirit essence, the higher the number of pills, and the stronger the effect.

If it is a blood essence that reaches sixty percent purity, Cheng Dan can also reach at least three pills.

The effect of the Blood Spirit Pill is naturally far greater than the blood quenching pill commonly used in the army, not only playing the function of refining the strength of qi and blood, but also directly improving the magic elixir of qi and blood bottlenecks.

One of the most important points is that it can make up for the loss of the human body's essence blood, which is not like ordinary blood, which involves the origin of the human body, and it is extremely difficult to replenish the essence blood consumed, and even affects the foundation.

"I don't know if my father will be able to renew his muscles and bones after taking the Blood Spirit Pill, and the codex doesn't say it clearly, so it seems that he still has to find an opportunity to ask Elder Geng. ”

......

Lin Yun could feel the blood aura in the air, this aura was much milder, and it was suitable for him to condense the strength of qi and blood, and he should barely be able to bear it when he absorbed it.

......

Lin Yun approached the stone, so that he did not rush to urge the Spirit Gathering Array, but first opened the alchemy handbook and recorded the method of controlling the Spirit Gathering Array.

The alchemy notes are different from the previous set of plants and trees, and it is more about the control of earth and fire, the refining of spiritual materials and refining techniques, and the essentials of becoming a dan, which also includes the refining of solid pills and quenching body pills, which are not so demanding on the fire, but there are many requirements for the extraction and refining of spiritual material essence.

Each kind of pill has a main functional main material, and other auxiliary materials are used for comprehensive and conditioning according to different situations, and in order to achieve the corresponding function, there must be a corresponding heat.

Lin Yunke only skimmed through the contents of the codex, and finally decided to learn to control this Spirit Gathering Array first.

The guidance method of the Spirit Gathering Array was not much difficult, it had been properly prepared by Elder Geng in advance, and Lin Yun only needed to follow the guidance on the codex to control the Spirit Gathering Array.

After Lin Yun was skilled in his heart a few times, he didn't hesitate, and opened the Spirit Gathering Array with qi and blood according to the records in the codex, and in an instant, the blood and qi permeating the entire space seemed to be attracted by the mysterious power on the stone platform, and quickly formed a cyclone visible to the naked eye in the space.

The speed was not fast, but this vision was quite amazing, and the pale red aura seemed to form a funnel, which penetrated into the entire body from Lin Yun's Baihui acupoint under the guidance of the formation.

Lin Yun only felt that the blood in his whole body seemed to be boiling, the speed of blood flow suddenly increased a lot, the frequency of his heartbeat also increased greatly, and the breath that seeped into his body was quite mild, just enough for Lin Yun to bear.

Lin Yun closed his eyes tightly, and a murmuring sound like a stream flowing came from his meridians.

There are a total of 60 human leg bones, and Lin Yun has completed 8 leg bones, 24 toe bones, and 32 bones have been tempered.

Therefore, Lin Yun decided to take the lead in refining the last 28 metatarsal bones on his feet.

......

"Whew......"

"Boom ......"

The sound of tiger and thunder came from the closed cave, but fortunately, it was recorded in the codex, and the prohibition at the door isolated the sound, so there was no need to worry about the "tiger and leopard thunder sound" alarming others outside.

The tiger roared, and the sky thundered.

The dull sound of tiger roar and thunder shook his whole body from Lin Yun's mouthpiece.

The powerful sound power caused the aura of the Spirit Gathering Array to fluctuate slightly.

Lin Yun sank his mind and gathered all the vibration power on his feet, and the hairs on the pores on his legs stood up with every breath.

There are constant red blood beads expelling from the pores.

Half an hour later, Lin Yun's consciousness came back to his senses, and he felt that the qi and blood in his body were still strong, and there was constantly blood and qi to replenish it, according to his previous experience, his muscles and bones would inevitably not be able to withstand this "Tiger and Leopard Thunder Sound" for half an hour, so he needed solid pills to generate blood and strengthen his bones, and he could continue to refine it the next day.

However, at this moment, Lin Yunzhi couldn't feel the discomfort in his legs, and the bloody aura gathered by this Spirit Gathering Array had already been reflected.

Lin Yun was overjoyed in his heart, so he didn't dare to slack off, and seized the time to continue refining his bones.

......

The aura in the air was still stable, and the cyclone on Lin Yun's head slowly turned.

When Lin Yun sank down again, he didn't notice that the small pot on his chest suddenly emitted a faint blue light.

The small pot was buried in Lin Yun's chest, and it was naturally impossible for him to detect it.

When the blood spirit cyclone continued to pour into Lin Yun's body, at this time, a subtle blood spirit aura seemed to be out of the control of the Spirit Gathering Array, and another force seemed to be dragging the blood-colored aura above his head into the spout.

One person and one pot were like this, and at the same time, they began to absorb the breath of blood above their heads.

......

Lin Yun didn't feel the discomfort of his metatarsal bones until two hours later, and this time he had completed four exercises with the help of the Blood Spirit Stone and the phalanges of the Spirit Gathering Array, and he could feel that his strength was even stronger.

When he opened his eyes and looked around, he found that the blood on the top of his head had actually turned into a small breath and drilled into his chest.

Lin Yun was shocked, thinking that something had changed.

Before, he clearly remembered that this breath entered his body from the Baihui acupoint on the top of his head, how could it be in his pocket at this moment.

Lin Yun hurriedly untied the belt in front of his armor, only to find that this breath had penetrated into the small pot, and at this moment, there was a blood line connected to the spout, and at the end was the cyclone overhead.

This small pot Lin Yun has always been regarded as a small ornament, and he carried it closely, and the changes of the small pot several times before were all coincidences, so Lin Yun saw the vision of the small pot for the first time.

Lin Yun immediately stopped the operation of the Spirit Gathering Array, and the cyclone above his head instantly dissipated, and the blood line linked to the small pot naturally dispersed.

Lin Yun hurriedly took off the rope tied to the ear of the kettle from his neck.

Pinch the small cyan pot in your hand and examine it carefully.

At the bottom of the small pot, Lin Yun saw two words, 'mend the sky'

The others are just like ordinary teapots, but they are very small, and they can't be used to hold tea at all, but are more like objects to play with.

The cyan lid of the pot attracted Lin Yun's attention, and this small pot obviously absorbed the blood aura on his head.

Lin Yun opened the lid of the pot, and what caught his eye was a crystal clear, bright red liquid the size of a fingernail, and the liquid exuded an extremely rich aura, this breath is aura, an aura that only extremely rare heavenly and earthly treasures can have.

"It's ...... Blood Essence. Lin Yun exclaimed in surprise.

The essence of plants and trees has been mentioned more than once in the collection of plants and trees and the alchemy codex, and if you want to refine the essence of spiritual materials, the requirements are extremely complicated, and the requirements for earth fire and refining people are extremely harsh.

The codex records that the essence of the four layers of purity is considered to be successfully refined, and the essence of the purity of the quenching is the ultimate quality, as for judging the purity of the extraction of the essence, it can be distinguished by the aura and color, the higher the purity of the extraction, the darker the color.

The four-layer purity essence is generally transparent, with the color of the spiritual material itself, while the six-layer purity blood essence is like the faint red in this diffuse aura.

And the blood essence in front of Lin Yun's eyes was not only surging with aura that went straight to the top of the cave, but also crystal bright and bright like blood.

In terms of aura and color, even if Lin Yun didn't know it well, he knew that the purity of this blood essence was far greater than that of the sixth-layer upper grade.

The essence aura was extremely strong, and Lin Yun knew that if he took a drop, he would definitely die of a violent body, and he could only take it if he refined it into an elixir.

......

Lin Yun's heart was beating wildly at the moment, and the small pot in his hand was shaking a little because of excitement.

If it weren't for the records in the Codex, no one would have been able to purify ten layers, at most eight or nine layers, because it would be impossible for any spiritual material to completely refine useless impurities.

If it weren't for such a sentence, he would have thought that what this pot contained was ten layers and ten purities of blood essence.

The purer the aura, the more abundant the aura.

Alchemy is to maximize the effectiveness of spiritual materials, how erysipelas is produced, that is, the impure essence in the refining process, the dross is combined with other auxiliary materials......

......

The blood essence in the pot was only a lump the size of a fingernail, Lin Yun was still uneasy, and with the meager blood essence in the air, it could be condensed into essence, this small pot could be regarded as a treasure.

Thinking of this, Lin Yun's hands suddenly felt a little hot.

"If anyone finds out the effect of this little pot, it will be very bad, think that this little thing is a treasure!
