Since you want to refine the Crossing Erdan, you have to prepare the materials for the Crossing Erydan, and this does not require Ye Ning to bother.

After Yue Xuan told Ye Ning about alchemy, that night, Yue Li and Yue Xiang came together and sent ten spiritual materials for Du Erdan.

Ye Ning took the two storage rings, swept them with his divine sense, and frowned, "How much does Your Highness need to cross Erdan?" ”

Yue Lidao: "Of course, the more the better!" ”

Yue Xiang said: "According to the rate of thirty percent, the master needs to give the princess at least three Erdan." ”

Ye Ning was stunned when he heard this, and his face showed a trace of strangeness, although he did not refine the Transitional Erdan with his own hands, but there was a detailed record in Su Cuiping's jade slip, and it was left by the predecessors of the Medicine King Valley of the Shenyou Sect, one furnace of the Erdan can roughly become one to three pills, even if it is a three-percent pill rate, it is a bit too outrageous to only have three spirit pills for ten materials.

Su Cuiping herself did not open the furnace to refine the Dou Erdan, but she was already a cultivator in the distraction period, and she was facing the threshold of breaking through to the merger period at any time, so she was figuring out the jade slips handed down by the previous grandmasters of the Medicine King Valley, pondering the experience of refining the Dou Erdan, and collecting the spiritual materials she needed by the way, but she didn't want to end up cheapening Ye Ning, in her storage space, there were several ready-made Dou Erdan spiritual materials, and they were all the best heavenly and earthly treasures.

Yue Li and Ye Ning are much more familiar, and they don't have as many scruples as Yue Xiang when they speak: "If Brother Ye can refine more Du Erdan, His Highness is willing to buy them all, and you won't need them yourself anyway, right?" ”

Ye Ning let out an "oh" and said, "What is the price of Du Erdan in the market?" ”

Yue Li said: "There is no market, otherwise." As the king of medicine, what did Bi Yaoqing do when he came to Fengcheng? Only at the auction of the Qinglan Empire. Occasionally, there is an elixir like Doerdan, and the price is often unimaginably high. The monks at the peak of distraction, all of their net worth, may not be able to photograph a single Doerdan, and they are often taken away by some big forces or sects. ”

Ye Ning couldn't help but groan when he heard this: "So, the Qinglan Empire may not have the ability to refine the Erjin Pill?" ”

Yue Li didn't hide it in this matter: "To be able to refine the Dou Erdan, the lowest is a high-level grandmaster or Dan King level, and the entire Tianxuan Sect does not have a high-level grandmaster-level alchemist, let alone a Dan King?" Not to mention the Qinglan Empire, the high-level elixirs such as the Crossing Pills and the Crossing Tribulation Pills at the auction. Almost all of them flowed out of the Danqi Sect or some ancient sects. ”

Glancing at the two storage rings, Ye Ning couldn't help but regret a little in his heart, if Du Erdan was as expensive as Yue Li said, after refining it himself, I am afraid it may not be a good thing, I don't know how many big forces will be targeted, if someone is caught and specially alchemized, it will be sad...... Unless you can enter the Nine Great Sects or a holy place like the Two Palaces and One Mountain, otherwise. No one can really bless him.

It seemed to have guessed Ye Ning's thoughts, and Yue Li said: "It's not that there is absolutely no one refining the Erjin Pill, it's just that the Dan rate is maddeningly low, and several Grandmaster-level Dan masters in the royal capital have refined it. Including the medicine king Bi Yaoqing. ”

Ye Ning was stunned when he heard this: "Bi Yaoqing can refine the Erjin Pill by himself?" ”

Yue Li said "um" and said, "It's just that the Dan rate is outrageously low, and the color is not high." At its best, the grades are only inferior. It's okay to use it for others, but he himself will never take it. ”

Ye Ning nodded slowly. Yue Li's sentence is equivalent to pointing him a clear path, someone asks for Du Erdan, no problem, exchange spiritual materials, the extremely low Dan rate can definitely make people who ask for Dan crazy, and the grade is not guaranteed, no matter whether the refining is successful or not, the fee charged will not be less, and if you really refine your reputation, no one will provoke you.

After weighing it in his heart, Ye Ning nodded and responded: "Okay, since the spiritual materials are ready, I will open the furnace for His Highness to alchemy as soon as possible." ”

Yue Li continued: "Your Highness still has a reluctant request, I hope that Brother Ye can fulfill it." ”

Ye Ning didn't care about Yue Li's messy title, and asked casually, "What's the matter?" Say it and see if I can help. ”

Yue Li hesitated for a moment before saying, "When Brother Ye opened the furnace for alchemy, His Highness wanted to observe from the side. ”

Ye Ning was stunned for a moment, and said in a deep voice: "His Royal Highness is also a cultivator of the Dan Dao?" ”

Yue Li shook his head: "Your Highness's cultivation is not the Dan Dao, nor the Formation Dao, the Sword Dao, etc., but a skill that has been handed down from ancient times, which is called the Way of Life, and there are also those that are called the Way of Spirit Planting." ”

Ye Ning couldn't help but be a little curious: "The way of life? The Way of Spiritual Planting? ”

Yue Xiang coughed lightly beside him and said, "Your Highness's skills are derived from an ancient jade slip, we don't know much, we can't explain it clearly for the master, why don't the master personally ask Her Royal Highness the princess for advice?" “

Yue Li was stopped by Yue Xiang's words, and he stopped continuing the topic of Fang Cai, and said directly: "After Your Highness saw Brother Ye's alchemy in Earth Flame Mountain last time, I felt that Brother Ye's alchemy technique seemed to have something in common with the way of life, so I started to take a look. ”

Ye Ning couldn't help but hesitate for a moment when he heard this, it wasn't that he was worried that his alchemy technique would be learned, but that there were some things that he really didn't want to be seen, such as the true fire of the sun, such as the Dan furnace in the Tenglong diagram, and his alchemy foundation was still the technique of the Dan Weapon Sect after all, these were impossible to hide from the real alchemy master, at least for now, he didn't want to reveal his details.

Being guessed that it is related to the Danqi Sect is not the main thing, I am afraid that it will be troublesome if I accidentally be recognized as related to the earth, the legend of the land of divine punishment, he has heard Chen Ying say more than once, several ancient sects in the immortal cultivation world have sent disciples to the earth, Ye Ning has personally experienced it, and for this reason, he also deliberately destroyed all the ancient teleportation arrays that can be found on the earth.

In the depths of his heart, Ye Ning actually regarded the earth as his hometown, and regarded it as private property and forbidden, and did not want to be contaminated by other forces in the immortal cultivation world, although this mentality was very strange, Ye Ning still did not hesitate to do so.

However, Yue Xuan's request is not good for him to refuse directly, otherwise, if the other party wants to achieve his goal, sooner or later he will think of other ways, which will be impossible to prevent, and it is better to show her generously.

"Your Highness is interested in this set of recipes, but you don't need to go to the alchemy room to observe them, I can give them to Your Highness," Ye Ning made up his mind after a slight change of thought, "The most taboo is distraction when alchemy, and the alchemy of the family has some taboos that should not be leaked, which is inconvenient for outsiders to observe." ”

"In this way, is there a successor to Brother Ye's alchemy?" Yue rolled his eyes away, and then asked.

"Since alchemy is a family tradition, it will naturally not be leaked, not to mention, my cultivation is still low, and I am not qualified to open the door to teach apprentices, even if I accept apprentices in the future, there are some privacy that should not be passed on." Ye Ning didn't care about the purpose of Yue Li's question, and simply blocked the possible loopholes.

"In this way, thank you Brother Ye, and allow me to return to Her Royal Highness the Princess, whether you want to observe it or not, it is up to Her Royal Highness the Princess to decide for herself."

Yue Li smiled and groaned, and then said goodbye to Yue Xiang and left.

Looking at the two storage rings in his hand, Ye Ning couldn't help but feel a little undecided.

The original plan was to use the Nine Dragons Danding in the Tenglong Diagram and his newly comprehended alchemy technique, plus the refining of the Sun True Fire and Taiyin True Water to refine the Crossing Erdan, in that case, although he had not refined the Transitional Erdan, Ye Ning was more than seventy percent sure of refining the best or even the best Crossing Erdan, but whether it was the Nine Dragons Danding or the Sun True Fire, the Taiyin True Water, or even his own original alchemy, it should not be leaked.

Don't say that Yue Xuan, who doesn't know the details, is a husband and wife, father and son, and some secrets must be maintained.

Ye Ning's secrets, no matter which one of them is leaked, will cause an uproar, and even invite death, so he can't help but be cautious.

If you agree with Yue Xuan to observe from the side, such as the Danding, Sun True Fire, Taiyin True Water, the concoction process of spiritual materials, etc., all need to be covered, there is no experience in refining Du Erdan, and with only a set of alchemy techniques that have just been comprehended, Ye Ning feels that he is not even sure of Yicheng.

Don't talk about refining Duerdan, as long as you don't blow up the furnace, it's good.

In that case, it will inevitably arouse Yue Xuan's suspicions, for the time being, it is not the result that Ye Ning wants, he finally found such a foothold, and it is also a very suitable opportunity to integrate into the Ziyuan Star Immortal Cultivation Realm, he really doesn't want to waste it.

No matter what Yue Xuan's real purpose was to observe the alchemy, he couldn't allow himself to categorically refuse, although Yue Li said it very tactfully, but Ye Ning also understood that this was just a temptation by Yue Xuan.

After pondering for a while, Ye Ning came up with a stupid solution.

First called Huang Ye and Zhuyun over, ordered the two to stay outside the quiet, and did not allow anyone to approach, and left a communication jade plate for Zhuyun.

Then returning to his own quiet room in the Danshi Mansion, Ye Ning activated the formation that had been arranged long ago.

The formation of the quiet room was carefully designed by Ye Ning, in addition to the white marble talisman used to arrange the formation, it also cost a rune refined by the divine technique, which not only isolated the divine sense from probing, but also had a great corrosive effect on the divine sense, and the Nine Heavens Divine Thunder Array was set into the isolation formation.

After confirming that the environment was absolutely safe, Ye Ning took out all the refining materials sent by Yue Li, and threw the two storage rings directly into the Qingxu space, but he was not worried about what hands and feet would be in them.

The mountains of materials were divided into categories, and then the Nine Dragons Danding was released, and the spiritual materials were processed one by one.

Use the Sun True Fire and Taiyin True Water to alternately quench the impurities in the spiritual materials, leaving only the purest spiritual material essence, and then all of them are included in the Qingxu Divine Beads, and after all the spiritual materials are processed, the spiritual material essence is filled with a white marble bottle.

These white marble bottles containing spiritual material essence have all been engraved with Ye Ning pattern, which can perfectly ensure that the spiritual material essence will not escape.

After careful concoction, and then refining in the Dan furnace of Earth Flame Mountain, coupled with that set of magical alchemy techniques, refining the Erjin Pill was a little more certain, and he no longer worried about Yue Xuan watching from the side, but how to explain to Yue Xuan still had to take a lot of thought.
