As an ancient treasure-level Dan furnace, once the Bagua Dan Furnace is opened, the consumption of True Yuan Power is also very terrifying, almost double the consumption of True Yuan Power compared to the Purple Cloud Pill Furnace that Qin Lang used before.

Fortunately, Qin Lang is also different from the past, and his cultivation has recovered to the peak of the middle Yuan Infant period, so it is still not a big problem to use.

Before the Bagua Dan Furnace is opened, there are still some special rituals to be carried out, this ancient treasure has not been used for a long, long time, so Qin Lang needs to perform a blood sacrifice to the Dan Furnace, using his own essence and blood as a guide, and once again complete the whole sacrifice from the inside to the outside.

In this way, it can also strengthen the individual's control over the entire Dan furnace, after all, alchemy is a very delicate job, much more cumbersome than manipulating magic weapon battles, and there is no room for the slightest sloppiness.

Next, the huge Bagua Dan Furnace was already suspended in mid-air under the action of Qin Lang's True Yuan Force, and as his True Yuan Force continued to enter, the forbidden formation pattern on the surface of the entire Dan Furnace had already appeared misty.

And Qin Lang bit his middle finger while inputting the True Yuan Force, spilling his essence blood on the Dan furnace.

"Hurry!"

Qin Lang bypassed the sacrificial refining method and smashed the essence blood into the Dan furnace.

"Boom!"

The entire Dan Furnace shook, and with the process of refining the essence blood, Qin Lang's mastery of this Dan Furnace became deeper and deeper, and he slowly reached the level of mastering the Purple Cloud Pill Furnace before.

In this way, it also represents the complete success of the entire essence blood sacrifice.

After the refinement of the essence and blood, the original gray Bagua Dan furnace has been completely dirty, the surface is dusty, and not even a trace of patina has come out, it looks like a very delicate and simple Da Dan furnace.

It's a pity that this ancient treasure-level Bagua Dan furnace can't change in size freely like the Ziyun Dan furnace, and the Ziyun Dan furnace can be big or small, don't think about it on the Bagua Dan furnace.

This is also the biggest difference between the ancient treasure and the current magic weapon, so the Bagua Dan furnace in front of him, which seems to be one or two tons, needs to occupy a lot of Qin Lang's storage space.

But this is also a helpless thing, who made Qin Lang an alchemist, the Dan furnace is a guy who eats, no matter how heavy it is, it has to be always ready to occupy storage space.

Fortunately, the Bagua Dan Furnace is indeed a penny of weight, and the yield of alchemy is much higher than that of the Ziyun Dan Furnace, which is also a little comfort in Qin Lang's heart!

Alchemy has finally begun!

The first thing Qin Lang refined was the Blood Yuan Pill, which was a pill that was commonly prepared to replenish qi, blood and vitality during the cultivation process of the Yuan Infant Cultivators, and the medicinal effect of one Blood Yuan Pill was almost comparable to that of twenty Jing Yuan Pills, and the effect was very good.

At this time, Qin Lang took out all the materials needed to refine the "Blood Yuan Pill".

"Demon Beast Inner Dan" is the main material, and it needs to be at least the fifth order or above Demon Beast Inner Dan.

If the level of the demon beast inner pill is low, it needs to enter the processing and refining to improve the quality of the inner pill, just like the fourth-order demon beast inner pill, often three or four can be condensed into a fifth-order one.

There is a batch of demon beasts in Qin Lang's storage bag, worth more than five million, basically all of them are trophies obtained from Green Willow City, and there are second-order, third-order, fourth-order, and fifth-order products, which are very messy.

However, Qin Lang was not afraid of trouble, and was ready to process and refine all the demon beast meat pills below the fourth order.

In addition, there are more than a dozen other auxiliary materials, which are also needed in the process of refining the Blood Yuan Dan, and the most of these auxiliary materials are the essence blood of the demon beast, and the essence blood of the demon beast is also the basis of alchemy, and the higher the grade, the better.

First of all, the processing and refining of the Demon Beast Inner Pill of the Blood Yuan Pill, Qin Lang had already raised the fire of Kanli and appeared at the bottom of the Bagua Dan Furnace, calcining this newly obtained Gubao-level Dan Furnace little by little.

And all the demon beast inner pills whose quality has not reached the fourth order are now put into eight small grids in the Dan furnace by him, this Bagua Dan furnace is based on the innate eight trigrams, and the grid in the first Dan furnace corresponds to a different hexagram, and the flame temperature required is also different.

In this case, Qin Lang would need to have a more refined fire control ability than manipulating the Purple Cloud Pill Furnace, but fortunately, Qin Lang was already strong in this item, and the cultivation in the middle of the Yuan Infant was enough to support the current strength of the alchemy, so it was not a big problem.

After putting the demon beast inner pill into the Bagua Dan furnace, Qin Lang closed the lid of the Dan furnace and increased the firepower to enter the calcination, the condensation of the demon beast inner pill needs a fierce fire, only in this way can the impurities of the inner pill be quickly burned, so that the quality of the inner pill is purer.

In Qin Lang's divine sense control, all the processes were proceeding in an orderly manner, however, in the process of alchemy, this Dan furnace treasure was full of energy, and the sound was huge, but Qin Lang did not expect.

In the past, when the Purple Cloud Pill Furnace was used to refine the Dan, there was no such huge movement at all, and the treasure light diffused by the Dan Furnace almost impulsed Qin Lang to place the prohibitions around him, if Qin Lang did not place the prohibitions around, it is estimated that this treasure light could rise to the sky, and it could be sensed within a radius of hundreds of miles.

High-profile, using this kind of Dan furnace to refine the pill is too high-profile, this is the only feeling in Qin Lang's heart now.

However, now that the arrow is ready to be issued, although Qin Lang regrets a little that he did not deepen the layers of prohibitions around him before alchemy, but now it is too late to regret it, I hope that Baoguang did not reveal too many prohibitions he had laid down, and did not alarm those monks who walked by in the Western Desert.

Fortunately, the process of processing and refining the Demon Beast Inner Pill was not very long, it had been completed in about one or two hours, and Qin Lang had processed thousands of Demon Beast Inner Dan this time, but most of them were second- and third-order Demon Beast Inner Pills, so when all of them were condensed into fifth-order Demon Beast Inner Pills, there were actually more than two hundred of them.

Coupled with the more than 100 fifth-order demon beast inner pills in the original storage bag, Qin Lang now had a total of more than 300 fifth-order demon beast inner pills in his hands.

With more than 300 fifth-order demon beast inner pills, refining a thousand Blood Yuan Pills is no problem at all, and even with the arc increase of 20% of the Dan furnace, you should get more.

At this time, after Qin Lang cleaned up the impurities of the Dan furnace, he did not immediately enter the second step, but began to strengthen the environmental prohibition laid around.

There is no way, the movement of the Bagua Dan Furnace Alchemy is too big, Qin Lang doesn't want to be well-known, if it is discovered by a passing monk, it will be very bad.

After rearranging it, Qin Lang began to pour the blood of the demon beast into the Dan furnace, and used the fire of Kanli to burn it violently, condensing it little by little to the concentration he wanted, and seeing that the base liquid in the Dan furnace was boiling violently, he added the demon beast inner pill to it.

Then, it's time to add other auxiliary materials.

The other dozen or so materials all need special techniques and sequences to add them, Qin Lang has already designed the order of adding materials in his brain, so everything is going on in an orderly manner.

As the forbidden talismans on the Dan Furnace were stimulated, and all of them lit up, the entire Dan Furnace was wrapped in a circle of light that shimmered with mist.

This aperture does not appear simply, it is also a reflection of the alchemist's own strength, only high-level alchemists will appear when refining pills.

Although the consumption of the Bagua Dan Furnace on the True Yuan Power was sixty percent more than that of the ordinary Dan Furnace, it was not difficult for Qin Lang, and the current Qin Lang was completely at ease.

Seeing that the aperture was finally generated, Qin Lang also breathed a sigh of relief, and the next thing to do was simple, it was nothing more than to maintain this aperture from disappearing, insist on him for about half an hour, and wait until all the materials added in it were completely melted.

And when the material is completely fused with the base solution, the base solution also changes from the original blood red to dark red, just like cinnabar, which is a sign that the base liquid is fully cooked.

At this time, it is time to start pumping out the water in the base solution and start to shake out the pills one by one, which is also called "Zhendan".

In this process, Qin Lang constantly played the alchemy law prohibition, acting on the Dan furnace, and there were almost more than a hundred kinds of prohibitions in just three or five minutes.

This is also because the level of the Blood Yuan Dan Pill is not very high, although the Blood Yuan Pill is a medium-grade elixir, it is also the lowest category in the middle grade.

In Qin Lang's memory, most of the high-grade pills required cumbersome alchemy procedures, and some pills even required more than one or two thousand alchemy forbidden methods during the refining process.

The first time he operated this kind of ancient treasure-level Dan furnace, it was fake to say that he didn't give birth to his hands, Qin Lang's forehead was already sweating slightly, and now the consumption of true qi was still secondary, but the test of his mind was definitely huge.

Fortunately, there was nothing wrong in all aspects, Qin Lang was also an alchemy master who had gone through many alchemy tests, so he gritted his teeth and survived, and now what bothered him in alchemy was not cultivation, but mental pressure.

After all, alchemy is a complicated process, the first time you use a new Dan furnace for alchemy, and you get a mid-grade spirit pill like the Blood Yuan Dan that has never been refined before, just like a driver driving a new car, and the performance of the car needs to be remastered.

However, in addition to consuming some more mind and cultivation, Qin Lang did not make the slightest mistake in the entire process of alchemy, and the whole process persisted smoothly, and finally the entire Dan furnace began to vibrate again.

Inside the closed prohibition, there was even a Dan explosion in the Dan furnace, which could be full of spiritual power of the pill, which was formed by constantly hitting the wall of the Dan furnace when the pill was not completed.

Although the refining procedures of the basic materials were complicated, and the consumption of the True Yuan Power and Mind of the Ancient Treasure Grade Dan Furnace was also very large, the process was very fast, and it only took less than half an hour.

Now, it's time to harvest Dan! Peng!Peng!Peng!Peng!Peng......!Peng

The lid of the Bagua Dan furnace was directly washed open, and Qin Lang also pinched the Dan Harvesting Law at this time, and with a wave of his big hand, he directly collected the finished pill that Hulala kept gushing out of the Dan furnace, the Blood Yuan Dan.

This time, the pills were produced a lot, counting at least more than 1,300, it was not enough for Qin Lang to fill all the blood jade bottles on hand, and then he simply decided not to use the jade bottles, and directly vacated the jade bottles, and put a lot of them into the storage ring.

This is also the fact that all the pills refined by Qin Lang have reached the perfect level of quality, so he dares to expose the pills in the air.

If the elixir does not form a perfect level of quality and fails to form a forbidden pattern on the surface of the elixir, it would be foolish to do so, because the elixir's elixir aura will continue to escape, and eventually the entire elixir will disappear directly.
