Yang Mu had long been aware of the charging standard of the Fire Vein Land from the mouth of the Spirit Guide, and the price was not low, ranging from fifty to two hundred spirit stones.

There is only one miniature fire vein in the Land of Fire Veins, which was established into fifteen secret chambers by the monks of the Flying Moon Sect, similar to the division of spirit stone grades, divided into four grades, the middle and upper poles.

Yang Mu has a heaven and earth spiritual fire, and after a year of refining, he has mastered one-third of his power, so he chose a medium-grade secret room, which is exactly ten days and a thousand spirit stones.

"Just during this time, no one came to the fire room below the top grade, Taoist friends, please put away the token, this is the second fire room control token in the middle grade, this token can control the prohibition of the fire room, but also control the supply of firepower. After ten days, the fire chamber will automatically open, and then the Taoist friends must come out. If the fee is less than 10 days, the fee for the remaining days will be refunded. If you don't open the fire chamber within three days, the timer will start automatically. Do you understand?"

"Understood...... Yang Mu took the token and walked in the direction the caretaker had pointed out.

The fire room is built underground with special fire attribute stones, and the interior is an empty square space, in the innermost position of the fire room, a blue spiritual light seals that small area, from the left section of the fire room to the right end, under the spiritual light, is the fire vein, and the token can be used to open the blue spiritual light, borrowing the power of the underground fire vein.

Yang Mu entered the secret room, but did not immediately refine the pill, but hurriedly took out the formation diagram of Xiao Kui Ming's Six Spirit Array, and laid out the formation according to the diagram.

The formation diagram has the formation layout method, as well as the position of the formation base. The position of the base of the formation can determine the area covered by the formation.

Yang Mu slightly changed the arrangement of the formation base, attracted the spiritual power in the fire room, and operated this set of formations, which only took more than three hours in total, and it was just arranged and running at dawn.

"With this formation, you can rest assured that you can refine the elixir. Yang Mu was still very satisfied, so he started alchemy with peace of mind.

He took out the alchemy furnace of the Venerable Master Ban Ling, opened the seal and prohibition of the fire vein, and the flame ignited in an instant, presenting a light blue flame, an extremely gentle flame.

The aura in the fire room is very good, it should be one of the best locations in Fang City, so Yang Mu dares to exhaust all the spirit stones, of course, he still has twelve drops of spiritual liquid to use, so he doesn't have to worry about running out of mana.

Yang Mu first took out the Lan Yan True Flame from the alchemy furnace and put it on the second layer, and then took out the Jade Slip of the Zhuling Pill Pill and put it aside, so that you can see the process recorded by the Danfang at any time.

Heiyuan Ganoderma lucidum, Qianjue root, honeysuckle ...... The elixirs were taken out one by one and put into the alchemy furnace respectively. The order and time of the medicine are recorded in detail on the Danfang, and Yang Mu himself has experience, so he can use his divine sense to explore the situation inside the alchemy furnace, and according to the refining of the elixir inside, combined with the Danfang method, put the elixir in order.

In the process of alchemy, it is necessary to constantly use mana to urge the flame, so that the temperature inside the alchemy furnace is constant and changes at any time, because in the process of alchemy, the situation of elixir refining is different, and the temperature needs to be adjusted in time.

This adjustment is a university question, and probably sixty percent of the reason for the failure of alchemy is this, the elixir is either refined, or the temperature is not enough, and the medicinal power of different elixirs cannot be blended.

In this regard, Yang Mu has experience and mana control is relatively perfect, so the process is very smooth. The alchemy technique performed is the recipe for enlightenment, taken from the alchemy books of the Venerable Master of Ban Ling, in addition to pondering the Dan prescription for more than a year, it is the secret art of penance, according to the Dan Fang, it can be used to build the spirit pill to increase the rate of Dan.

It takes time to refine the elixir, Yang Mu has calculated, three days can refine a furnace, two days have passed, the elixir has been thrown in, the medicinal power has been refined, into a gas in the furnace by the hot gas tumbling.

The next step is to melt the pill, which is to melt the gas-like medicinal power into the pill, and the medicinal power will converge into a solid state. It is also necessary to control the temperature, as well as the mana control to urge the alchemy furnace to melt the pill.

The alchemy furnace has the function of refining medicine and melting pills. The grade of this alchemy furnace of Venerable Ban Ling is not low, and it belongs to a high-grade magic weapon, so the loss of mana in this process is not very large.

However, Yang Mu was only a Qi Condensation Cultivator, so he took a drop of spiritual liquid to last until now.

One day's Rong Dan was quite smooth, and he almost failed in the middle, but Yang Mu used his experience to save the Spirit Pill.

Finally, it is Cheng Dan, the formation of the pill, absorbing the aura of heaven and earth, showing the formation of a layer of diaphragm, without this layer of diaphragm, the elixir is easy to disperse, the process of dispersion is very fast, and no one has time to recover.

The previous process was very smooth, but in the last link, when Yang Mu opened the alchemy furnace, he suddenly made a mistake, and it was not his mistake, it may be that the Venerable Master Ban Ling did not record the details on the Danfang, which led to the failure.

"Cheng Dan failed, it was ...... just now" Yang Mu was not discouraged, and was still summarizing the reasons.

After stopping and thinking about it carefully, combined with the content on the Dan Fang, Yang Mu felt that it was a bit of a deviation, because it was a deviation caused by the use of earth fire instead of the monk's true fire.

In the second refining, Yang Mu was obviously much more proficient, refining the medicine and melting the pill, all of which went smoothly, and the time was shortened, and the two processes only took twenty hours.

The last Cheng Dan, Yang Mu grasped it very well, of course, there were twists and turns, after all, Cheng Dan is extremely dangerous, and there will be the possibility of exploding Dan.

Yang Mu wantonly consumed mana, trying his best to promote the formation of the elixir, and under the control of his ingenious alchemy secret technique, he finally succeeded, and a pill the size of a small thumb with a white light floated on the alchemy furnace.

As soon as Yang Mu sucked the mana in his palm, he sucked the elixir over. Looking at the Spirit Building Pill in his palm, Yang Mu smiled, "Finally refined, one step closer to building the foundation." ”

After a short rest, Yang Mu did not completely relax, took the third drop of spiritual liquid, fully recovered his mana, and began his third alchemy, which was still a spirit pill.

The more pills you take, the better you take, the higher the chance of breaking through the bottleneck. Yang Mu planned to refine the third elixir, and with the experience of two times, he was more confident.

The third time was about the same as the second time, and the time was almost the same, and in order not to affect the alchemy, Yang Mu took the spiritual liquid in advance to ensure that the mana was sufficient.

Succeeded, the second spirit pill was successfully refined, and it was a little stronger than the first spiritual power, and the quality was higher. With two Soul Pills and auxiliary Tsuki-Pills, the chances of building a foundation must be greater.

There was still a little time left, nearly two days, and Yang Mu was a little hesitant at this time, he hesitated whether to use up the elixir in the storage bag to refine the Tsukidan and refine the third Tsukidan.

After thinking for a long time, Yang Mu suddenly became firm, and said secretly in his heart: "I have already taken one Tsukidan, and the two Tsukidan may not be strong enough, this time we must succeed in building the foundation." ”

After saying that, he took another drop of spiritual liquid and restored all his mana, and Yang Mu began his fourth alchemy, but this time it was not the Zhuji Pill, but the Zhuji Dan.

For the refining of Zhuji Dan, Yang Mu is experienced, the deity of the spiritual world has been destroyed, the pill that built the foundation was refined by himself, and he wasted eight elixirs to refine two Zhuji Dan, and the foundation was successful.

The process of opening the furnace for alchemy is very different from the refining of the spirit pill, and the links are basically the same. This time there was only one elixir, but Yang Mu already had two Tsukidans on his body, so his pressure was not so great.

In less than two days, it was just enough for him to refine Tsukidan. The firepower of the fire vein, after eight days of release, was a little unstable, and Yang Mu could only increase the firepower of the Blue Flame to maintain the amount of fire required by the alchemy furnace.

Refining medicine, fusing the pill into a pill, plus the final special primer, the process of priming the base only needs to be used on the Zhuji Dan, and the base force of the medicinal power is the power of the medicinal power foundation formed by the fusion of the four main drugs.

When the furnace is opened, the elixir emerges, absorbs the aura into the pill, and then introduces the base. Yang Mu has his own secret technique of inducing foundations, and he began to cultivate a long time ago, in order to be able to refine the foundation building pill by himself one day.

Today finally came in handy, Zhuji Dan succeeded, and it was a one-time success, which shows that Yang Mu's alchemy is extremely clever.

Even Yang Mu himself didn't expect that Daxi would come to Tsukidan, "Haha...... It was a one-time success, and it seems that this time I will definitely be able to build a successful foundation. ”

After loading the refining elixir, Yang Mu had just put away the alchemy furnace, and the time was up, the door of the fire room was opened, but the prohibition was not put away.

Yang Mu quickly put away the Xiao Kui Ming Six Spirit Array, put it in a storage bag, and left the fire room, and before going out, he handed in the token.

After he left, a monk from the Flying Moon Sect entered Yangmu's fire room, not like he had come to alchemy, and breathed heavily, as if he was looking for something.

"It's the scent of Tsukidan, and this person is refining Tsukidan. This kind of danxiang should be successful, but I don't know how many times it has been successful. "This person can actually smell the smell of the pill to judge the refined pill.

With the result, this person didn't stay long, and walked directly to the Elixir Pavilion of the Flying Moon Sect after leaving.
