There are many methods of alchemy, and the common method is "direct refining", the so-called "direct refining", which is to put the ingredients required for alchemy into the ding at one time, and ignite the fire to directly refine the pill.

Another method is "qu refining", which is a technical work, first only a few main 'medicines' are loaded into the ding, and then every once in a while, one or several 'medicines' are added to it.

The advantage of this method is that it is simple, and the disadvantage is that it is difficult to master the heat, and it is easy to refine the pill 'medicine' if you are not careful.

The most important thing to pay attention to in alchemy is the heat, if the heat is not enough, the 'medicine' mud will not become a pill, and if the heat is too much, the pill 'medicine' will be burned to ashes, so refining some important pill 'medicine' generally does not need to be "directly practiced".

During this period of time, Yaqian, Sun Ruyun and Abu 'Hua' stayed in the alchemy room almost day and night, repeatedly figuring out the pill-making technique against the classics, and warming up for refining the "Nourishing Soul and Tranquility Pill".

Under the leadership of Yaqian, they tried while figuring out, and they practiced dozens of pills in total, and the hundreds of bundles of low-level spiritual 'medicines' sent by Guo Yan were all practiced into various pills by them.

I don't know how many days and nights have been spent, they have tried a variety of alchemy methods, and have accumulated enough experience in making pills, whether it is "qu refining" or "direct refining", they have reached the level of perfection.

Xu Dong asked the pots and shovels to arrange for guards to guard the practice pill room, and took more than 300 kinds of spiritual 'medicines' from the Horse Mansion, and after everything was ready, he and the three 'women' went up to the furnace for alchemy.

In addition to mastering complex techniques, refining the "Nourishing Soul Pill also requires the alchemist to have a certain amount of skill, and generally refining this kind of superb pill is refined by a professional alchemist.

Now, Xu Dong personally 'operated' the knife and took charge of the plate, and three 'women' took him as his deputy, and after two days and two nights of busy work, they pounded more than 300 kinds of spiritual 'medicines' into 'medicine' mud.

Xu Dong was about to use two alchemy furnaces to alchemy at the same time, and he recited the "fire initiation formula" in his mouth, using this formula to lead the earth fire, and then let the earth fire and the alchemy furnace be connected, and the bottom of the two alchemy furnaces ignited a whirring flame.

Xu Dong used "qu refining", he first put a part of the spiritual 'medicine' into the two Ding furnaces, and after these spiritual 'medicines' were refined into semi-finished products, he added the second batch of 'medicine' mud, and then added the third batch of 'medicine' mud.

During the refining process, he had to open the "Heavenly Eye" of the Purple Mansion to observe the color of the furnace fire, that is, to see if the fire was lacking or too much, and constantly worked towards the Ding furnace to control the temperature in the Ding furnace.

A few times the morning and dusk passed quietly, and all the 'medicine' mud had been refined to eight points of finished products, and only the three flavors of the top-grade spiritual 'medicine' were put in to refine, and the two furnaces of "Nourishing Soul and Tranquility Pills" were finally completed.

He took out the three flavors of the top-grade spiritual 'medicine' from the treasure bag, first tried to put Chi Jinlian into the furnace, gathered all the 'essence' and listened to the movement inside, this kind of peerless top-grade spiritual 'medicine' was a test for the Dan furnace.

Because any kind of peerless spirit grass is ten thousand times higher than the aura of other spiritual 'medicine', it suddenly increases the density of spiritual elements in the furnace, and if the quality of the furnace is not good, it will burst because it can't withstand the pressure.

For the Dan-making group, the "bursting furnace" is the last thing an alchemist wants to encounter, which can be scrapped if a furnace has been refined into a medium-ripe pill, or the tragic outcome of the furnace being destroyed and people dying.

Therefore, before Xu Dong added Chi Jinlian, he found an excuse to give Yaqian, Sun Ruyun and Abu 'flowers', not letting these three 'women' follow him into danger, and leaving the consequences to himself alone.

There was a light explosion sound from inside the furnace, and the two Dan furnaces began to tremble, even the foundation under their feet was shaking slightly, and the entire alchemy room seemed to be 'pumping' the wind.

Xu Dong was also secretly ready to escape, after all, this was the first time he had refined the best pill, and it was certain that there were some not very good factors, and he had thought of all the consequences in advance.

The good thing is that this 'pumping' wind quickly stopped, the light explosion sound in the furnace weakened little by little, and gradually changed from dense to loose, the two Ding furnaces recovered their previous stability, and a thick 'medicine' fragrance wafted from the alchemy room.

Xu Dong's hanging heart fell to the ground, he knew that the quality of these two Dan furnaces was extremely good, and he couldn't help but guess that Ma Wu and Xiong Pi must have used them to refine some high-level spirit pills before.

Now, he was no longer worried that the Ding Furnace would not be able to withstand the pressure, so he put the Old Death Immortal Grass into the Ding, and after the Old Death Grass was integrated into the pill 'medicine', he added another peerless top-level spiritual 'medicine': Baigu Sanxian 'Flower'.

After adding the three flavors of peerless top-level spiritual 'medicine', the Dan 'medicine' has become nine minutes cooked, and there is still one last process before the Dan pill refining is completed, which is to introduce the true fire into the Ding furnace.

True fire comes from the cultivation of Inner Dan in Taoism.

The superior takes heaven and earth as the furnace, the sun and the moon as the water and fire, the 'yin' and yang as the chemical machine, the lead, mercury and silver sand as the five elements, the 'nature' as the dragon and tiger, the thought as the true seed, the heart refining the thought as the fire, and the rest of the thought as the fire.

Hanguang is solid, subduing the inner demon is the field, the body and mind are the three essentials, the heart of heaven is the entrance, and the love comes to the 'sex' for Dancheng", which is called the best way to prolong life, which can prove the fairy fruit.

The top multiplication is the ether void as the tripod, the Tai Chi is the furnace, the purity is the Danji, the non-action is the dantian, the 'sex' life is lead and mercury, the determination and wisdom are the water and fire, the suffocation 'desire' and punishment are the water and fire 'intercourse', the 'sex' and the unity of the emotions are the gold and wood, and the heart is bathed.

Sincerity is determined to be solid, precepts, determination, and wisdom are the three essentials, the middle is the entrance, the clear heart is the fulfillment, the "sex" is condensation, the three elements are "mixed" for the holy womb, the "sex" life is a piece for Dancheng, and there is a body outside the body to be reborn, and the void is broken in order to be.

In the past, when he saw the Imperial Sword Master refining the Ji Dan, Xu Dong had seen him introduce the True Fire into the Ding Furnace, although he did not get the true inheritance of the Imperial Sword Master, but he also comprehended it in his future cultivation.

He extracted the true fire from the dantian, and confidently poured the three 'color' flames into the furnace, and the real fire burned coagulantly in the Ding furnace, and many tongues of fire were splashed from the inside of the Ding to the outside.

Xu Dong heard the sound of baking and burning coming from the furnace, and the blazing real fire was 'stirred' and 'swinged' out, like a liquid that could flow poured out of the Ding furnace, and the flowing flame completely enveloped the entire Ding furnace.

The pill that has been refined with real fire has taken off the mundane taste of the pill' 'medicine', making the aura in the 'medicine' tens of thousands of times purer than before, reaching the ultimate of "being wonderful in form and spirit, and true in harmony with the Tao".

Xu Dong planned to use half a month to refine the "Nourishing Soul and Tranquility Pill", but it only took ten days to complete, Dancheng opened the furnace three days later, opened the lid of the Dan furnace, and saw a pill 'medicine' fragrance overflowing.

After taking the "Nourishing Soul and Tranquility Pill", Xu Dong only felt that the whole body was comfortable, and the pulse was active and smooth, and on this day he watched with internal vision in the basement of the "Hua'jing' Palace", and found that there was an oval-shaped placenta in the body, and a fetus was sitting in it.

"It's not enough to only have 'Nourishing Soul Pills', the growth of the fetus also needs a variety of nutrients, not only vegetarian, but also meaty, you have to find a way to 'get' some meat to nourish the fetus. ”

Xu Dong was startled, and the Holy Infant turned into a golden body more than a foot long and floated in the air at some point, covered in gold, illuminating the dark underground dark room as bright as day.

"Master. Under the 'ray' of golden light, Xu Dong had to 'daze' his eyes, "What do you mean by meat, what does this mean." ”

Holy Infant said, "What do you mean, didn't I say that you need to take various nutrients during this period to help the development and growth of the Dao fetus in your body, such as tonic some demon pills or something." ”

"Tonic Demon Pill, where do you get this thing from, whether you have to buy it in the market, and how many grains you have to eat to make it work. ”

The Holy Infant said, "There is no public sale of this thing in the market, even the underground black market cannot have a high-quality demon pill, and the price will be ridiculously expensive, even you, the monarch of the Luo Tuo Kingdom, may not be willing to buy it." ”

"What do you say? ”

"Because it is very dangerous to hunt demon beasts, demon beasts are divided into twelve levels, starting from the third level and corresponding to the cultivation realm of human beings, that is to say, the fifth and sixth level demon beasts are equivalent to the monks of the Yudan realm. ”

The Holy Infant continued, "That is to say, there is no pill in the body of the demon beasts below the fifth level, and if you want to get a good quality demon pill, you have to hunt the seventh or eighth level demon beasts, and these demon beasts are equivalent to the Yuan Infant Realm and above." ”

Xu Dong said, "Then what should I do, you mean that if you want to 'get' the demon pill, you have to go out and kill the demon beast yourself." ”

The Holy Infant nodded approvingly, "You're right, you will have enough food and clothing by doing it yourself, besides, the process of hunting demon beasts is actually very enjoyable, there are both stabbing 'excitement' and fun, and more importantly, 'exciting' people's courage and wisdom." ”

Xu Dong thought about it and said, "It seems that there are not many demon beasts on land, and most of those high-level demon beasts live on the bottom of the sea, so I'd better go to Wuliang Island." ”

The Holy Infant waved his little hand again and again, "No, no, no, you don't have to go back to Wuliang Island now, just hunt some fifth- and sixth-level demon beasts in the Demon Beast Mountain, at this stage, it is too dangerous for you to hunt too high-level demon beasts." ”

"Moreover, even if you hunt a fifth- or sixth-level demon beast in the Demon Beast Mountain, you can't go alone, for the sake of safety, you must bring a few other people who are above the Yudan realm to hunt together. ”

Xu Dong knew that the name of the Demon Beast Mountain was Taishou Mountain, and in the place where the Luotuo Kingdom bordered the Longcheng Country, most of the demon beasts were driven to the sea during the pioneer period, and only a small number of demon beasts were entrenched in Taishou Mountain.

He said, "Cultivation is above the Jiedan Realm, there are only a few people in the Pure Yang Palace, except for a few national teachers, there are only a few Dharma Protector Elders, I can't transfer these old guys to help me hunt." ”

The Holy Infant said, "Who asked you to transfer those Dharma Protector Elders, I mean how many people should be taken to take care of them, I think, you can take the Great Master and the Three Kingdoms Teacher." ”

Xu Dong thought about it, and had no choice but to let the newly appointed Great Power Division, Xue Ying, the head of the Wind Chasing Dao, and the Three Kingdoms Division follow him to Taishou Mountain, and after making up his mind, he was ready to go out of the underground dark room and call Xue Ying and the Three Kingdoms Division to call Xue Ying and the Three Kingdoms Division.

"Before you go to Taishou Mountain, bring those pills refined with low-level spiritual 'medicine', because those demon beasts are usually hidden in 'holes' and 'holes', and they are not easy to be lured out, so you can use these pills as 'lure' bait. ”
