The pattern on the back of this palm-sized bronze plaque is a grand palace, and the front is engraved with the five seal characters of "Haotian Disciple Order", Wang Chuan can't see anything special when he turns over and over, he explores the inside with his divine thoughts, and he doesn't find any forbidden magic array, and tries to inject mana, but this bronze medal is like a mortal thing in the world, and there is no way to inject mana.

After some tossing, the bronze medal did not see anything unusual at all, it was an ordinary bronze medal, anyway, it didn't take up any space, so Wang Chuan casually threw it into the storage bag.

Wang Chuan's good luck seems to have run out, and the subsequent search has found nothing, the most critical item that can help get out of trouble has not been found, Wang Chuan's fiery mood because he got a low-grade spiritual weapon has also quickly declined, and he can't get out of being trapped here, even if he gets a high-grade or even a top-grade spiritual weapon, what can he do?

The aura in this mysterious palace is very strong, the peak of Xuandu is far inferior, I am afraid that only the main peak of the hidden dragon can be compared with it, a few weeks later, Wang Chuan's meridians are faintly painful, it has reached the limit of bearing, there is also a cycle of day and night in the spiritual realm, Wang Chuan's Taiyin alchemy can also be cultivated here.

After a few days, except for mentioning some spiritual cultivation and health preservation scriptures and Taiyin body refining techniques, the rest of the time Wang Chuan sat silently in a daze, staying alone in this empty Huoyun Palace, and now Wang Chuan can still use the time of cultivation to calm down, but after a long time, I am afraid that it will become like a walking corpse, and even cultivation will feel that it is meaningless.

During the period, he tried to break through the palace gate once, only lasted for a short time, and then returned to the Huoyun Hall scarred, Wang Chuan sadly found that in the face of the overwhelming stone beasts, it was impossible to break out.

"Something to do, or you're going to go crazy. Wang Chuan turned his gaze back to the jade slip on the bookshelf.

In the next half month, after Wang Chuan cultivated, he plunged into the Dan Dao, but he didn't let go of a word of anything that could be read.

Alchemy was extremely novel to Wang Chuan, it was like a completely new world, and Wang Chuan immersed himself in it with great interest, gradually forgetting that he was in a difficult situation, and seemed to have forgotten to find a way to escape from this Jedi.

Immortal cultivators all have super memories and have the ability to never forget, so theoretically speaking, Wang Chuan is now not inferior to any alchemist in the Xuantian Continent, from the basic selection of medicinal herbs to the use of Danding, how to control fire, and the techniques of Ning Dan are all clear in his heart.

What's even more rare is that there are also a lot of Dan prescriptions recorded in the jade slips, from the Qi Nourishing Period to the Pei Yuan Period, the Jin Dan Period, the Yuan Infant Period and even the Yuan Shen Period, but the strange thing is that there are no Dan prescriptions of Pei Yuan Dan in it.

There is nothing to do left and right, anyway, being idle is idle, Wang Chuan moved the idea of refining a furnace of Dan by himself, the Qi Nourishing Period Dan recorded in the jade slip is called Jingyuan Dan, which can greatly enhance mana, and the effect is extremely obvious, and even the early stage of Peiyuan can be taken, but the effect is not as good as the Qi Nourishing Period.

Wang Chuan recalled the Dan prescription of Jingyuan Dan: "The main medicine is the hundred-year-old Poria cocos fruit, plus ice lucidum grass, red meadow, and stone crystal mushroom. ”

"Wait" Wang Chuan seemed to remember something, and raised his feet and walked towards the right side of the Fire Cloud Palace.

"If I'm not mistaken, those hundreds of jade boxes contained the elixir for refining the Jingyuan Pill. "I opened a few jade boxes and looked at it, and sure enough, the type, amount, and quantity of the elixir were just right.

After thinking about it, Wang Chuan took out a jade slip called "Alchemy Primer", sat on the ground and studied it carefully, this alchemy primer record is not a profound key, but some basic operations, detailed, simple, and popular language.

An hour later, Wang Chuan put down the jade slip in his hand, closed his eyes and simulated the entire alchemy process in his mind, before getting up and coming to the edge of the Earth Fire Cave.

took out the Nine Yan Ding and placed it at the entrance of the cave, and then a magic decision hit the fire rune array, the rune array was faintly lit up, and the light and shadow on the Dao array flowed, and after a while, bright yellow flames erupted from the cave entrance.

Wang Chuan immediately put the hundred-year-old Poria cocos fruit into the Jiuyan Ding, and Shen Nian paid attention to the condition of the elixir in the Ding and the strength of the earth fire, after half a cup of tea, a wisp of black smoke came out of the Ding, and a scorched smell then drifted away, "The earth fire can't be too strong at the beginning, it has to be slowly strengthened little by little." Wang Chuan quickly found the answer to failure.

Half an hour later, a scorching smell rose again in the Nine Flame Ding, "When several flavors of elixir fused, the heat was not well controlled. ”

Third ......

......

Seven or eight consecutive alchemy attempts have failed, looking at the scattered jade boxes on the ground and the slag of refining waste on the ground, Wang Chuan simply stopped, "If so many failures are measured by spirit stones, I'm afraid that thousands of spirit stones have been wasted." Although there are still many elixirs in the jade box, Wang Chuan doesn't want to waste them senselessly.

Sitting on the ground, Wang Chuan took out the "Alchemy Primer" and looked at it quietly.

The next morning, Wang Chuan summoned the earth fire again, and began to try again, Shen Nian felt the temperature of the Jiuyan Ding, Wang Chuan put the Poria cocos fruit into the Ding, and paid full attention to this white spirit fruit, with the slow increase of the earth fire, the temperature in the Ding also increased, and after half an hour, the Poria cocos fruit gradually melted, turning into a ball of pure medicinal liquid.

After the Poria cocos fruit is completely melted, Wang Chuan put the ice mushroom grass and the red meadow into the ding at the same time, this ice mushroom grass is the water attribute, the red manofoam belongs to fire, water and fire are combined, used to reconcile the fierce medicinal properties of the hundred-year-old Poria cocos fruit, these two elixirs are put into the Ding, Wang Chuan has several consecutive spells in his hand on the fire rune array, and the originally gentle flames suddenly burst out.

As the earth fire scorched violently, the ice mushroom grass and the red meadow slowly softened and merged into the medicinal liquid, and after half an hour, the three elixirs had completely fused together, turning into a viscous liquid with golden yellow mixed with black spots.

After the variegated color in the liquid completely disappeared, Wang Chuan threw the last elixir Shi Jingzhi into the ding, this Shi Jingzhi was extremely poor, the whole body was inconspicuous earthy yellow, and the appearance was like a tree root, but it was a rare auxiliary medicine that could gather and lock the medicinal power.

After Shi Jingzhi was also fully integrated, Wang Chuan breathed a sigh of relief, he was lucky, the first difficulty of refining Jingyuan Dan was successfully passed, and the next step was to refine the impurities in the liquid medicine and purify the liquid medicine.

The magic in his hand changed, and the fierce earth fire instantly turned into a gentle flame, and after an hour, the viscous liquid was purified to the extreme, and the speckled black spots had disappeared, turning into a loose sphere of irregular fist size.

"The prototype of the pill has appeared, and the following is the biggest difficulty, the Ning Dan has taken shape. ”

Wang Chuan took a deep breath, expelled the distracting thoughts in his mind, and quickly pinched it with both hands, and one after another the magic decisions continued to hit the Nine Yan Ding and the Lihuo Fu Array, and at the same time concentrated all his divine thoughts in the Ding, paying attention to the slightest change in the prototype of the elixir.

With the continuous calcination of the earth fire, the loose and loose embryonic form of the pill in Dingzhong slowly condensed, and the volume became smaller and smaller, and the irregular surface of the original pitted potholes gradually became smooth and smooth.

At the last moment, Wang Chuan let out a low shout, and a magic duel hit the talisman array, and the fire suddenly exploded to the extreme, the bright yellow flames turned into a tyrannical crimson, and the surging flames wrapped the Nine Flame Ding inside.

The raging earth fire only lasted for a few breaths, and then quickly receded, but unexpectedly, there was a "snort" sound from Dingzhong at this time, and a thick smell of burnt paste spread along with the black smoke.

"It should be the time of Ning Dan, and the fierce fire has lasted a little longer." Wang Chuan's face was as calm as ever, analyzing the possible reasons for the failure.

In the next few times, Wang Chuan still failed to refine the Jingyuan Dan, and each time the Ning Dan was either late or early, either the fire was too fierce and the medicinal properties were damaged, or the fire was not enough to cause the Ning Dan to fail.

Seeing that it was getting late, Wang Chuan stopped practicing and began to practice the Taiyin Body Refining Technique.

Early in the morning of the second day, Wang Chuan did not start alchemy, but turned around and came to the alchemy book on the left, took a brief look, and took out a jade slip of "Ning Dan Tips" and read it.

An hour later, Wang Chuan put down the jade slip in his hand, closed his eyes and crossed his legs and pondered quietly, looking like he had gained.

......

Wang Chuan stared at the Jiuyan Ding tightly, the magic in his hand continued to play, the pill in the Ding gradually took shape, and the earth fire immediately surged out violently, the temperature in the Ding instantly reached the extreme, and the explosive red flame only lasted for a short period of time, and began to slowly retreat, as the temperature in the Ding dropped rapidly, a silver-white pill with a round and flawless body was quietly suspended in the Ding.

Wang Chuan made a move of his hand, and the thumb-sized elixir slowly flew in front of him, and a refreshing fragrance permeated the surroundings.

After carefully studying for a moment, Wang Chuan inhaled his mouth, and the pill turned into a streamer and went straight into his mouth, as soon as this Jingyuan Pill touched his lips and teeth, it suddenly melted into a gentle stream and penetrated into his abdomen, and then turned into a stream of spiritual power that permeated his body, feeling the abundant pure spiritual power on his body, Wang Chuan hurriedly sat down and ran the health sutra to absorb this huge spiritual energy.

An hour later, Wang Chuan stood up, but his eyebrows were full of joy that could not be concealed, "This little Jingyuan Pill is actually worth ten days of penance! ”

The Qi cultivation period may not be deep, but after the mana reaches the advanced realm, the accumulation and polishing of mana is a long process, and it can be counted for years at every turn, and it even takes ten years and a hundred years to get it, and the elixir at that time is even more effective in assisting cultivation.

This Jingyuan Pill can be said to have a huge effect on the monks in the Qi cultivation period, enough to make cultivation a thousand miles a day, and even in the early stage of Peiyuan, it can be taken, but the effect is not so obvious, and one pill may only be worth one day of cultivation.

In the following days, Wang Chuan kept alchemy and serving pills every day, and his alchemy techniques became more and more proficient, from the earliest success rate of about three or four percent to fifty percent, and then six or seven percent, and in the end, although Wang Chuan did not dare to say that he was 100% successful, but at least ninety percent of the certainty was still there, and the pills of each furnace of pills also increased from one to three, and finally fixed at about five.

Two months later, the original more than two hundred full jade boxes turned into empty boxes in one place, in exchange for Wang Chuan's cultivation that had reached the peak of the ninth order, as well as dozens of jade bottles filled with Jingyuan Dan in the storage bag.

Feeling the abundant mana that he had never had in his body, Wang Chuan was very satisfied, and the next thing was to polish the mana carefully every day, compress and refine it as much as possible, and then wait for the breakthrough.
