On the day of practicing the Tong Gu Pill, Long Chen asked Meng Qi, Chu Yao, Tang Wan'er, Lu Fang'er, and Gu Yang to take it as soon as possible, assisted by the medicinal power, and opened up the tendons of all bones.

The bones are connected by veins, but only the outer bones, and the bone marrow part of the bones is connected by blood vessels.

However, in order to refine bones, especially the whole sacrifice, it is far from enough to rely on the input of blood vessels, and it is necessary to reopen a channel in the tendons and veins, reaching the depths of the bone marrow.

The power of this kind of elixir can be directly injected into the bone marrow through the tendons and veins, nourishing the bones at the fastest speed and facilitating the absorption of the bones.

This speed is hundreds of times faster than the output speed of blood, so when they reach the powerhouse of the Bone Sacrifice Realm, they all open a channel on the tendons and veins to refine the bones.

Generally, the strong people in the Bone Sacrifice Realm are going to sacrifice their bones one by one, and it is enough to open up one tendon and vein each time, so the Tong Gu Pill they use, even if it is a relatively garbage lower grade pill, is enough.

And the dragon dust chose the whole sacrifice, to be one-time, open up all the meridians, connect all the bones, then gritted his teeth and used the unicorn fruit as the main medicine to refine the Tonggu Pill, otherwise the medicinal power could not be reached, and it could not be penetrated at one time, then it would be troublesome.

However, with the Phoenix Bird Purple Flame and the Qilin Fruit, the Tonggu Pill refined by dragon dust, although it is only a fourth-order mid-grade, it is also the best of the medium-grade, comparable to the fourth-order high-grade elixir, which is enough for them to open up the tendon and vein channel.

During the period when the four women took the pill and retreated, Longchen did not delay and began to practice.

A large amount of Sanhua Tongjin Pill is swallowed, and at the same time, the divine ring is opened, absorbing the aura of the outside world, and assisting in cultivation, both at the same time.

Three days later, when Meng Qi and the others finished refining the pill, and Long Chen also entered the Yijin Four Heavens, Long Chen found that while eating the pill and cultivating at the same time would make his cultivation twice as effective with half the effort, but it was a pity that he didn't have so much time to practice.

And Meng Qi and the others, without the slightest surprise, opened up the muscles and veins of the whole body, which must be thanks to the powerful medicinal power of the unicorn fruit.

In the past three days, Guo Ran has also broken through to the Bone Forging Realm, but he has only just broken through, so Long Chen needs to let him consolidate the realm before he can eat the Bone Pill, otherwise the foundation will be flawed.

And Ah Man, Long Chen secretly handed over the corpses of the Wind Barbarian Beast and the Purple Feather Phoenix Sparrow to him, and asked him to go far away, find a hidden place to eat them, and don't let the little Purple Feather Phoenix Sparrow see it.

Ah Man excitedly ran away with two huge corpses, and Longchen told him to eat the purple feather phoenix sparrow first, destroy all the evidence of the crime, and then deal with the wind brute beast.

These are two powerful fifth-order demonic beasts, and they have ancient bloodlines on their bodies, which are much more powerful than the fifth-order demonic beasts in the outside world, which is tantamount to sending charcoal in the snow for Aman.

Although time was relatively short, Longchen did not carefully examine Aman's body, but he still felt that some kind of power was slowly awakening in Aman's body.

This made Longchen more and more convinced that Ah Man was a barbarian person, and they didn't need to cultivate, they just needed to keep eating, and they could become the strongest warriors.

Such an anti-heaven race, I'm afraid there are only barbarians, when Longchen fought so desperately for two corpses, it was also for Aman, what he needed most was flesh and blood.

The flesh and blood of the two demonic beasts were handed over to Ah Man, but their bones were left behind by dragon dust, because their bone marrow was a necessary raw material for refining the Sacrificial Bone Pill.

In the bone marrow of the monster, there is a violent energy, and the dragon dust needs to remove the violent energy in the bone marrow, leaving the most essential part to make the raw materials for the sacrificial bone pill.

The quality of the Sacrificial Bone Pill is often related to the quality of the main medicine, and Longchen believes that the Sacrificial Bone Pill refined from the bone marrow of two ancient demonic beasts is definitely much stronger than the Sacrificial Bone Pill sold on the market.

During the time when Longchen was extracting bone marrow and refining marrow powder, Longchen arranged a task for Guo Ran, Tang Wan'er and others, and he gave six people seven pills, asking them to see which kind of pill they could get together with the medicinal materials in their hands.

These seven Dan prescriptions, all of them are the formulas of the Sacrificial Bone Pill, Longchen knows seven different formulas based on the memory of the Dan Emperor, if this news spreads, it will definitely make the outside world crazy.

Because in the outside world, there is only one prescription for sacrificial bone pills, so the medicinal materials for sacrificial bone pills are extremely scarce, and the major sects are desperately planting, but they are still in short supply, and the price of sacrificial bone pills has always remained high.

This is also the reason why countless Bone Forging Realm powerhouses can only sacrifice one or two bones, because the price of the Bone Sacrifice Pill is too expensive, so expensive that people can't afford it.

Just because there is only one kind of Danfang, the consumption of medicinal materials on it is too large, and it has become in short supply, even if it is planted desperately, it cannot meet such a large demand.

Because the medicinal materials on the sacrificial bone pill need to be at least more than 100 years old, otherwise the medicinal effect will not reach and will not meet the requirements.

And Long Chen wrote seven pill formulas in one go, and if he said it, it would definitely shock the entire alchemy world.

However, the five people in front of him are the most trusted people in Longchen, and Longchen is not afraid that this secret will be leaked to the outside world.

"Boss, seven Dan Fang, you can only make up three, according to the amount you said, I'm afraid it's less than a thousand. Guo Ran said with some concern.

Although Guo Ran didn't understand the art of alchemy, he knew the basic common sense, a pill, a normal Dan master, can refine two or three finished pills, which is already good.

There is only a master level, and you can refine four to five finished pills in one furnace, and it depends on a certain amount of luck.

And those so-called masters are all old guys who have been practicing Dan all their lives, and they are so experienced that they are scary, so they have such a high success rate.

Since there is a success rate, there is a failure rate, and once it fails, the entire furnace will be smashed away, and there will not be even a single hair left.

Therefore, even if it is a thousand medicinal herbs, if you can refine three thousand finished pills, it is already an incomparably amazing success rate.

Three thousand sacrificial bone pills are enough for one person to refine eight bones, but what Longchen wants everyone to choose is the whole sacrifice, this pill is obviously a drop in the bucket, so everyone's mood is extremely dignified.

"Hehe, you don't have to worry, I said that the matter of alchemy belongs to me, you just need to cultivate with peace of mind.

Three thousand ordinary pills are indeed nothing, but three thousand fourth-order high-grade pills are different. Longchen said with a smile.

"Fourth-order high-grade, boss, can you do it?" Guo Ran was taken aback.

"Boy, remember in the future, don't question whether I can do it or not, this is extremely insulting for a man," Longchen warned.

"This sacrificial bone pill, when it comes to refining techniques, is much simpler than the Tong Bone Pill, and I am sure that I can refine the top-grade sacrificial bone pill.

It's a pity that this Dan furnace is too rubbish, and I don't dare to use it with all my might, otherwise I have the ability to refine a high-grade Dan with gorgeous patterns" Long Chen sighed.

Although there are still some Dan furnaces in his hands, they are all garbage Dan furnaces, and he doesn't dare to use them with all his might, otherwise he will blow up the furnace.

And the dragon dust has not been done yet, it can be used as the realm of the Danhuo furnace, and without the Dan furnace, nothing can be done, so it can only be refined.

"During this time, I'm going to start alchemy, Mengqi and Gu Yang, the five of you will retreat with me, I have refined the sacrificial bone pill, you will immediately start refining the bones" Longchen said.

"Then what am I doing?" asked Guo Ran.

"You are responsible for guarding us, and during this time, there will be brothers from other courtyards coming one after another, and you are responsible for picking it up" Longchen said.

Gu Yang suddenly interjected: "Why don't I go with Guo Ran, in case an enemy comes, the two of them still have a care, I feel that someone is secretly peeping at us." ”

Longchen pondered for a moment, nodded and said: "It's okay, those people who are secretly peeping at us, I have long been aware of it, you don't have to pay attention to it, it should be the spies of some forces."

They just came to wait and see, and did not dare to really do it, if they dared to come out to provoke, remember one word - kill, kill mercilessly.

From today onwards, anyone who maliciously provokes us will be killed directly, regardless of good or evil, and I will be assured and bold to kill!"

"Okay, just wait for the boss's words, Made, these bastards, you should teach them a lesson, otherwise they will always treat us as soft persimmons" Guo Ran said with some gear.

Longchen glanced at Guo Ran and reminded: "Now don't mess around, don't go out to provoke others, and have time to quickly consolidate the realm." ”

"Hehe, boss, look at what you said, I, Guo Ran, am I such a person who doesn't know the severity" Guo Ran sneered.

However, Guo Ran was really a little weak-hearted, because he did have an idea just now, that is, after the dragon dust retreated, he would lead out the people who were secretly peeping at them one by one, either they were idle or idle, and they always wanted to find something to do, but they had to dispel their original thoughts when they were reminded by Long Chen.

"Gu Yang, look at this kid, now is not the time to talk nonsense, there will be a shocking battle soon, this is related to whether we can leave the secret realm alive" Longchen said to Gu Yang, compared to Guo Ran, Gu Yang is still more stable.

"Boss, don't worry, I'll watch him" Gu Yang nodded, and now Gu Yang, like Guo Ran, calls Longchen the boss, feeling that this title is more cordial.

"Well, I still have four Bone Pills here, and there are brothers who have broken through the Bone Forging Realm here, you let them open up the veins first.

At that time, Mengqi and the others should have sacrificed some of the bones, and then they came out to protect you, and everyone took turns to sacrifice the bones, so that there would be no waste of time," Long Chen advised.

"We understand," Guo Ran and Gu Yang said with serious faces.

After telling the two of them, Long Chen took the four girls and entered the tent, and the whole tent was ten zhang square, which was very spacious.

Tang Wan'er had previous experience with dragon dust alchemy, and told the three of them how to assist in dragon dust alchemy, and how to classify the refined powder into bottles.

With the assistance of four people, Dragon Dust doesn't need to care about anything, only needs to refine each piece of medicinal materials into medicinal powder.

Most of those herbs were fresh, and their own essence had not been lost much, and they were full of medicinal properties, coupled with the strength of the purple flame, all the medicinal properties were firmly locked in the medicinal powder, which made Long Chen's heart feel a lot more comfortable.

However, the workload is very large, nearly a thousand medicinal materials need to be refined, and the dragon dust is busy for a whole day before it is completed.

This is still with the help of Purple Flame, if it is the previous beast fire, it will not be completed at all in a month, and it will also lose a lot of medicinal properties, for Purple Flame, Dragon Dust likes it from the bottom of my heart.

After all the medicinal powders were refined, the dragon dust rested for half an hour, put his spirit at the peak, and began refining the Sacrificial Bone Pill. For mobile phone users, please visit http://m.piaotian.net
