In the early morning of the next day, after Zhao Sheng finished his daily homework, he flew the sword and skillfully flew to the foot of the sunset peak.

The sword light dissipated, and Zhao Sheng entered the belly of the mountain from the cave at the foot of the mountain, walked through a long road, and came to the front of the Earth Fire Room area.

Today, the guards at the door changed a group of people, and as soon as Zhao Sheng wanted to enter, he was blocked by a tall armored man next to him.

"What about passpasses? You can't get in without a token! ”

This armored man was obviously not smart, and he didn't even see the Keqing token deliberately worn by Zhao Sheng's waist.

Zhao Sheng shook his head secretly, and then released his foundation building realm momentum.

"I made an appointment to meet in the fire room. Get out of the way! ”

"Building the foundation... Seniors, please! ”

When the armored man sensed Zhao Sheng's momentum of building the foundation, he was immediately startled, and hurriedly claimed that it was.

He just took two steps back, but he suddenly hesitated, and his expression was twisted and he wanted to stop but didn't dare to stop, so he had to look at Zhao Sheng with a tangled gaze.

Seeing this, Zhao Sheng felt quite funny in his heart, so he took off the Keqing token and handed it to this person: "Do you recognize this?"

Dahan scratched his head and said embarrassedly: "Yes, this is the Keqing token." Seniors, please! The juniors have only been here for two days. If you have just offended your seniors, please forgive your sins! ”

Zhao Sheng saw the other party's witty apology, so he nodded lightly at the big man and walked into the corridor.

Walking through a passage paved with fire-sheltered bricks for several hundred meters, Zhao Sheng appeared in a very spacious circular grotto.

The temperature in the grotto is very high, with an average of more than 40 degrees, and the hot air is mixed with all kinds of medicinal smells and incense.

This grotto is built entirely by precious flint stones, with a diameter of nearly thirty or forty zhang and a height of five or six zhang.

On the stone walls around the grotto, there are eight almost identical, two zhang high and wide black Yongdao, and the top of the Yongdao entrance is engraved with A, B, C, D and so on.

At this time, there was no one in the grotto, but from time to time there were one or two muffled sounds in the depths of the tunnel, and occasionally there would be a faint sound of scolding coming from the fire room.

According to Jin Dancheng, the alchemy room of Sunset Peak has opened up a total of eight pillars of earth-centered fire, which are divided into sixty-four earth-fire eyes, that is, there are sixty-four earth-fire rooms.

The further the serial number of the earth fire chamber of each corridor, the better and more stable the quality of the earth fire, and the higher the success rate of the corresponding alchemy.

The D Earth Fire Room on Jiazi Road is Jin Ming's special alchemy room, and Zhao Sheng's destination is also here.

In front of the Jiading Earth Fire Room, after Zhao Sheng's divine sense transmitted the sound inside, the stone door quickly opened automatically.

Zhao Sheng walked into the room, Jin Ming stood up from the futon, shook his head with a wry smile and said, "Zhao Daoyou, you really gave me a big surprise!" If I knew that your basic skills were so solid, I wouldn't let the apprentice be ugly. ”

Waving his hand to close the stone door, Zhao Sheng walked closer in two steps, and said with a smile: "Jin Daoyou, don't blame me." Zhao didn't expect the noble disciple to teach so simple and simple. ”

Jin Ming stretched out his hand to signal Zhao Sheng to sit down, and said depressedly: "It's also because I didn't figure it out in advance!" However, have you ever heard the ancient proverb that 'everything can be turned into medicine, and everything can be alchemy'. ”

Zhao Sheng nodded when he heard this, and said with a smile: "I understand what Jin Daoyou means. Of course, I don't take this step lightly. ”

"That's right! When Taoist friends first set foot in Dan Dao, they can understand the true meaning of this, which is really gratifying. Ordinary alchemists will only use the concocted elixir to alchemy, but they don't know that a real alchemist will concoct the elixir by himself, so as to be familiar with and accurately control every penny of the elixir, so that the elixir refined is not only more in quantity, but also three points higher in quality.

As for the alchemy masters and even the Dan Dao Grandmasters, they are the beings who turn decay into magic. The birth of each new elixir is often accompanied by more explanations of the medicinal properties and pharmacology of unknown elixirs, which also means that the way of alchemy has a new development.

Zhao Daoyou, have you ever heard of the elixir of "marrow elixir"? ”

Zhao Sheng bowed his head slightly and said, "The Marrow Spirit Pill is so famous, of course I've heard of it."

Jin Mingtan's expression was slightly excited: "Daoist friends can know that five thousand years ago, there was no marrow elixir in the Heavenly Pillar Realm. At that time, no one thought that the brain marrow fluid of the demon beast could be used for alchemy.

It wasn't until the appearance of Grandmaster Chen Mo, when he was still an alchemy apprentice, that this idea came to mind. After nearly a Jiazi's painstaking exploration, Grandmaster Chen Mo finally succeeded in refining the first marrow elixir: the dragon whisker fish marrow pill. ”

Without Zhao Sheng's support, Jin Ming's speed of speech became faster and faster, "The Fish Marrow Pill can actually improve the spiritual power of immortal cultivators, and the price is very cheap. This is simply contrary to normal Dan theory. As soon as the dragon whisker fish marrow pill was born, it immediately triggered an unprecedented discussion. There were very few people in the entire Shattered Star Sea Alchemy Realm who supported Sect Master Chen Mo, most of them were criticism and ridicule, and some even thought that the Dragon Whisker Fish Marrow Pill had great hidden dangers and must be destroyed as soon as possible.

At this critical time, Sect Master Chen Mo actually refined the second kind of marrow elixir: the marrow pill refined with the brain essence of the deformed sea chapter. The Chapter Essence Pill is still an elixir that can improve the spiritual power of immortal cultivators. ”

At this time, Jin Ming spread his hands with a mocking expression, and said with a wicked smile: "After the Chapter Myelin Pill is the Golden Crystal Beast Myelin Pill, and then a series of Myelin Pills. Grandmaster Chen Mo used iron-clad facts to refute the world's doubts about him. The faces of the alchemists who mocked him were swollen. Today, after thousands of years of expansion and improvement, the elixir has grown into a well-known category of elixir. ”

After listening to his words, Zhao Sheng touched his chin and suddenly said, "Daoyou said so much, does it mean that the first spirit pill you taught me to refine today is the marrow spirit pill?"

"That's right! Zhao Daoyou is really smart, no wonder he succeeded in building the foundation at such a young age. Today I am going to ask you to refine the Dragon Whisker Fish Marrow Pill. It is a first-order elixir, and the difficulty of refining is not high, so it is very suitable for practice. Jin Ming couldn't help but praise.

With that, he took out twelve bottles and cans from the storage bag, and finally took out a square porcelain box.

When the porcelain box was opened, there were nine fist-sized transparent glass bottles, which contained a slurry half a finger deep and clear like jelly.

Zhao Sheng looked down, and Jin Ming also opened the other bottles and cans one by one, and asked, "Do you remember the Dan prescription of the Dragon Whisker Fish Marrow Pill?"

"Remember! One piece of dragon whisker fish marrow liquid, three coins of Zhilan stone powder, three taels and six coins of five leaves, and one corpse of thirty-year-old insects......" Zhao Sheng said skillfully.

Jin Ming smiled happily when he heard this, and praised: "Zhao Daoyou, you are really very attentive. However, alchemy is an extremely practical skill, and no matter how much Dan Fang knows, it is better to try refining a spirit pill. ”

"Come, let me introduce you to the facilities of this fire chamber first."

With that, Jin Ming stood up from the futon and walked to the center of the stone room, and Zhao Sheng also walked behind him and carefully observed the surroundings.

I saw that the whole fire room was roughly circular, with an area of about four or five zhang, and the surrounding stone walls were all flintstones. In the middle of the stone chamber, a one-foot-high stone platform was built, and in the center of the stone platform there was a circular pit the size of a bucket and a depression.

On the outside of the pit, the whole circle is inlaid with eight arm-thick earth fire pipes, and the mouth of the pipe is a red clam head, and the red clam's big mouth is open. And the mouth is tilted up, just above the center of the pothole, and the spitting posture is very realistic.

At this time, Jin Ming had already taken the initiative to explain to Zhao Sheng, pointed to the pit and said: "This is the mouth of the earth fire, and the earth fire is spewing out from here." However, refining a first-order elixir generally does not require the main fire port, and it is enough to use these eight fire vents.

You see, this red clam has a fire adjustment array embedded in its mouth, and it can use its spiritual power to adjust the size and height of the earth fire. Of course. Fellow Daoists, it is more convenient for you to use your divine sense. ”

Speaking of this, Jin Ming changed his words and said: "Although the Earth Fire Alchemy Pill is convenient, it is not as good as using the Heaven and Earth Spiritual Fire after all. Daoist friends must try their best to refine a heaven and earth spiritual fire when they have the opportunity in the future. Otherwise, it will not be able to give full play to the potential of Jiulong Ding. ”

Zhao Sheng nodded silently after listening.

At this time, Jin Ming briefly said a few precautions for alchemy, as well as the rules for the use of the earth fire room.

The use time of the earth fire room is calculated as one day, and fifty merits are required in one day, which is eighty yuan a day in exchange for spirit stones.

If you don't have enough merit points, you can also rent them for a few hours. But it takes at least three hours to start.

"Okay, for the time being, let's start alchemy!"

After Jin Ming finished speaking, he turned around and returned to the futon and sat down cross-legged. When Zhao Sheng saw this scene, he rarely felt a little excited and nervous in his heart.

He immediately sat down next to Jin Ming, released his divine sense, and watched Jin Ming's every move with all his attention.

"Go"

After a low drink, a silver-white three-legged Danding suddenly swelled several times, turned into a Dan furnace the size of a water tank, and flew down to the pit, and the bottom of the furnace covered the pit tightly.

"First of all, the first step, warm the Dan furnace!"

With this explanation, Jin Ming pinched the magic technique with both hands, and eight spiritual lights flew out of his fingertips one after another, shooting into the mouth of the red clam, and disappeared in a flash.

In the next second, eight clams spewed out eight thick cyan flames, and the flames converged to the bottom of the Dan furnace, and suddenly a large area of cyan earth fire burned fiercely.

After a few breaths, the temperature in the earth fire chamber rose rapidly, the air became hot, and the silver and white pill furnace quickly became hot.

Jin Ming continuously played one alchemy trick after another and hit the alchemy furnace.

After a while, the walls of the furnace began to redden.

At this time, Jin Ming's expression was serious, and he said in a low voice: "There are countless alchemy techniques, but they are roughly divided into fire refining and water refining, and now the mainstream of Dan Dao is mainly fire refining. You see, I'll start adding elixir right now. ”

As soon as the words fell, the lid of the silver-white Dan furnace suddenly opened a gap, and Jin Ming pointed to the bottles and cans on the ground in front of him with his hand.

I saw a four-foot-long, arm-thick, and light-blue scaled insect corpse suddenly flying out of a clay pot with a thin top and a thick bottom.

The insect corpse flew high, flew over a distance of more than a zhang, and fell into the Dan furnace.

At the same time, Jin Ming hooked his fingers, only to see the gray powder in a transparent glass bottle flying out and quickly submerging into the alchemy furnace.

Bang!

The furnace lid suddenly returned to its original position, and Jin Ming continuously played the spiritual light spell, and the ground fire of the eight red clams weakened a lot, becoming finger thick.

While observing the Dan furnace carefully, Jin Ming did not forget to explain to Zhao Sheng: "Now this step is to refine the Danji, and the time is about two quarters of an hour."

Zhao Sheng touched his chin, and his heart gradually became excited.

In the past two lives, although he had not tried alchemy, he had spent a lot of time studying alchemy in his spare time.

Therefore, he is not unfamiliar with the way of alchemy.

Zhao Sheng knew that the success of the elixir mainly lay in the refining heat of the elixir during alchemy, the degree of fusion of medicinal properties, and the most crucial grasp of the time of becoming a pill.

The time is early, the elixir has not yet been fused, and the elixir has not been formed.

When the time is late, the pill will burn into a pile of dregs.

As for the ingredients and quantity of the elixir put in, after countless practical summaries of the predecessors, it is clear what is said on the Danfang, and there is generally no need to worry about these.

Of course, if you want to improve an elixir and appropriately increase or decrease the quantity or purity of certain elixir ingredients, it is not impossible, as long as you can afford the loss of alchemy failure.

But when it comes to simplicity, it is really difficult to put it into practice!

There is a saying in the world of cultivating immortals: "Poor talismans are rich in refiners, and there are mineral alchemists at home." ”，

There is a saying that "the sun and the moon are a few years of instruments, and only one life of alchemy is bitter." ”

It is said that the cost of resources and time spent on cultivating an alchemist is too high.

There are only two difficulties, one is to accurately control the heat of the Dan furnace, and the other is to accurately grasp the opening time.

These two difficulties can be called the nightmare of any alchemist, and even the alchemy master will inevitably admit that the success rate of alchemy is really not high. If you have a success rate of more than half of the refining of the rank elixir, you can celebrate it in a big way.

It is recognized in the immortal cultivation world that alchemy is an extremely experience-based and highly practical skill.

In terms of difficulty coefficient, in the hundred arts of cultivating immortals, it is only under the divination and formation, which is completely difficult to learn and master, and difficult to advance.

Thinking like this, two quarters of an hour flew by.

"Next, smelt the medicinal properties!"

Jin Ming let out a low snort, and several auxiliary elixirs flew out of the bottles and cans in front of him one after another, and at the same time as the lid of the furnace was opened, they fell into the Dan furnace just right.

"Fire! Three quarters of an hour, pay attention! "The more concentrated Jin Ming's spirit, the more concise he becomes.

As several spiritual light spells were played out by him, the ground fire spewed out by the eight red clam's mouths suddenly thickened, and the temperature in the room rose rapidly.

At this moment, Zhao Sheng's expression changed, and a look of shock flashed on his face.

He is the foundation building realm, and he has already given birth to divine consciousness.

Compared with Jin Ming, who only relied on observation and experience, Zhao Sheng's divine sense had already penetrated into the alchemy furnace, and he used his divine sense to accurately observe the smelting of the elixir in the furnace and the many phenomena of medicinal precipitation and mutual reaction.

It's intuitive and shocking!

Divine consciousness can be called an alchemy weapon, and it is also the advantage of the foundation building monk.

When Zhao Sheng observed the reaction changes of the elixir in the furnace little by little, and secretly remembered all the reaction phenomena, time passed little by little.

Three quarters of an hour later, a fist-sized, light-brown semi-solidified pill liquid floated up and down in the center of the alchemy furnace, and under the invisible high temperature, the medicinal properties in the pill liquid were about to completely merge.

In the earth fire room, Jin Ming occasionally played a pill trick, and controlled the intensity of the fire at all times, and a few drops of sweat oozed from his forehead.

But at this time, he didn't care about wiping it at all, and estimated that the fire was almost over.
