"Uncle Hui, I have been trying to refine the pill recently, but I always fail to refine it. Lu Chen said simply, but he didn't say what kind of pill he was refining in public. The Nine Treasure Quenching Bone Pill is a necessary pill for cultivating gluttonous Devouring Heavenly Scriptures, and in the entire Nine Shadows Continent, except for himself and Gu Linglong, no third person knows the detailed Dan recipe and refining method of the Nine Treasure Quenching Bone Pill.

Fei Ying saw that Lu Chen had scruples, so she didn't ask more, she thought for a while, and said to Lu Chen, "Come with me." After that, Fei Ying took the lead. In the envious gaze of everyone, Lu Chen followed. The two of them left the Jingtang and went to the alchemy peak that belonged to Fei Ying in the Dan Hall.

"He seems to be the only inner disciple of the mine hall, Chen Lu. ”

Fei Ying and Lu Chen went away, and at this time, someone finally confirmed Lu Chen's identity. After confirmation, everyone became more and more envious of Lu Chen's good luck. Because the matter of the death of the medicinal materials in the medicine hall was resolved, Lu Chen was directly promoted to an inner disciple by Fan Sheng. Now Lu Chen actually knew Elder Fei Ying, one of the three elders of Dantang, and he also received special preferential treatment from Fei Ying.

"This kid can't be the illegitimate son of an elder of the sect, right?" In addition to envy, some people even secretly made shocking speculations.

Qin Qi and the others were also shocked and envious. Fei Ying is one of the three elders of the Dantang, and she is usually busy with the alchemy of the sect, so she rarely comes to the Jingtang to teach. Even if she comes, after the lecture, Fei Ying will immediately leave the scripture hall and return to the alchemy peak of the Dan Hall. It will not be like Fu Kuan, who taught fire control techniques, although the lecture is over, Fu Kuan will stay in the teaching stone room for a period of time, patiently answering questions for the disciples of the sect. And so far in teaching, Fei Ying has not taken anyone to her alchemy peak, Lu Chen is the first!

......

Dantang, the alchemy peak of the exclusive Fei Ying.

"After the lecture, don't you still have to answer the questions of the sect disciples?" Lu Chen asked in surprise.

Fei Ying smiled and explained to Lu Chen, "The first time you came to audit my lecture, you don't know my teaching habits. If it weren't for the successful refining of the spirit-level top-grade Tianming Pill, how could I have time to go to the scripture hall to teach the class. After I finish my lessons, I don't stop in the lecture room. ”

"Tell me about your alchemy. Fei Ying said with a smile.

Since this was the case, Lu Chen didn't think much about it, nodded slightly, and roughly said the process of refining the Nine Treasure Quenching Bone Pill, as for the matter of using the power of the sea to cast the Flame Fire Dragon to refine the pill, he naturally hid it.

And based on his dictation alone, although Fei Ying would know that nine kinds of medicinal materials would be used to refine the Nine Treasure Quenching Bone Pill, he would not be able to master how to refine the Nine Treasure Quenching Bone Pill. After Fei Ying listened, she groaned slightly, and then a smile appeared in her eyes, obviously she saw the crux of Lu Chen's alchemy failure.

"You failed in alchemy because you didn't know that there was such a thing as a knot spirit array. Fei Ying said slowly.

"Knot Dan Spirit Formation Diagram?" Lu Chen was slightly surprised, it was the first time he had heard of the Knot Dan Spirit Formation Map, his eyes looked at Fei Ying, and he quietly waited for Fei Ying's next words.

Seeing Lu Chen's humble appearance of asking for advice, Fei Ying bowed his head slightly, and patiently explained to him, "If an alchemist wants to refine a furnace of elixir, he needs many, many conditions. For example, the alchemy formula, many medicinal materials, the flame required for alchemy, its own fire control technique, alchemy furnace, etc., are all indispensable. In addition, if you want to succeed in alchemy, you also need to form a spirit formation. ”

Lu Chen's brows furrowed slightly, according to what Fei Ying said, if you want to succeed in alchemy, you must also master the Jie Dan Spirit Formation Diagram. But when he first refined the Nine Treasure Quenching Bone Pill, he didn't know about the Formation Formation Diagram, but he had a sixty percent success rate. Moreover, Fei Ying's refining of the spirit-level high-grade Tianming, as well as today's refining of the Qi Gathering Pill, Lu Chen did not notice that she had cast the Formation Formation of the Formation of the Spirit. After thinking about it, Lu Chen told the situation when he first refined the Nine Treasure Quenching Bone Pill, as well as the many doubts in his heart.

After listening to Lu Chen's many doubts, Fei Ying smiled indifferently, "Alchemy requires many conditions, and flame is one of them. The essence of fire is condensed from the essence of the earth fire, and like the demon beast spirit fire, it is more suitable for alchemy than ordinary earth fire. The level of flame power you used for the first time in alchemy is high, and it is mainly assisted by the Fire Spirit Mink. And the fire spirit marten has always followed the Younuo alchemy, and it is not weaker than the mortal-level alchemist. Due to the assistance of the Fire Spirit Mink, your own role in mastering the Jie Dan Spirit Array has been greatly weakened. In the end, even if you don't master the Formation Diagram, you will be able to succeed in alchemy. But this time, there was neither the essence of fire, nor the spirit fire of demon beasts, nor the assistance of the fire spirit mink, so the disadvantage of not mastering the knot spirit formation diagram was immediately apparent. ”

"And when refining the Tianming Pill and the Qi Gathering Pill, I had already engraved the Formation Formation Diagram in advance, and I used it in an instant, not to mention that you can't see it, even if a Xuan-level alchemist who is one level higher than the Spirit-level Alchemist is watching from the sidelines, I don't want to see through my Formation Formation Diagram. The knot pill spirit array diagram is an alchemist's secret that cannot be learned, unless it is passed on to a disciple in person. Fei Ying said the importance of the Formation of the Dan Spirit.

When Lu Chen heard this, his heart suddenly changed.

"Relax. Fei Ying said suddenly.

At this moment, Lu Chen only felt a soft feeling coming from the center of his eyebrows. When he looked over, he saw that Fei Ying had closed his eyes, and she pressed her softly on the heart of his eyebrows. Immediately, he felt that a powerful spiritual force was extremely docile, and in a very gentle way, it wanted to rush to his sea of consciousness through his eyebrows.

At this moment, there are only Lu Chen and Fei Ying on the Alchemy Peak, and this powerful spiritual power naturally belongs to Fei Ying, and Fei Ying seems to want to convey some kind of information to him through spiritual power. And when his Zhihai Dragon Gate arrived with this powerful spiritual power, there were faint signs of being ready to come out. Sensing this, Lu Chen hurriedly stabilized the Zhihai Dragon Gate, and between the lightning and stone fire, he hid the Zhihai and took the initiative to open the Zhihai Dragon Gate, allowing Fei Ying's spiritual power to enter his Zhihai.

Fei Ying's spiritual power was like a little flame, entering a pitch-black room where she couldn't see her fingers, lighting up a curtain of light, and Lu Chen's sea of knowledge was all hidden in the darkness that Fei Ying's spiritual power could not illuminate. Fei Ying didn't use her spiritual power to spy on Lu Chen's secret, and after a while, her spiritual power retreated, leaving only a pure spiritual power message.

Lu Chen was not in a hurry to use the power of knowing the sea to touch the spiritual power message left by Fei Ying, his eyes looked at Fei Ying, only to see that Fei Ying's eyes showed a trace of exhaustion, her face was also very pale, her white forehead was condensed with crystal beads of sweat, and even her breathing was a little unstable, looking overconsumed.

"I have left a diagram of the highest level of the Formation Pill Spirit Formation in my mind with the method of spiritual power inscription. When you go back, meditate on the center of your eyebrows with your own mind, don't be in a hurry, try slowly. With your qualifications, you can sense the spiritual power information I left behind in as little as one cup of tea, or as long as two or three hours, and wait until you have thoroughly mastered this pair of knot spirit array diagram before starting alchemy, you should be able to improve a lot. Fei Ying explained slowly.

After a pause, Fei Ying said weakly again: "My mental power has been consumed a lot, and I need to recover." After finishing speaking, he waved his hand to Lu Chen, signaling that Lu Chen could leave Alchemy Peak.

The reason why she didn't hide anything was that she directly taught her knot spirit formation diagram to Lu Chen. First, it is to return Lu Chen's favor, after all, the spirit-level high-grade Tianming Pill can be successfully refined, and Lu Chen plays a key role. Second, Lu Chen has a purple gourd and is the person chosen by the old master.

"Uncle Xie. Lu Chen got up and thanked him, although he didn't know the reason, but he knew that the knot pill spirit array was a secret that could not be passed on to an alchemist, and it could not be learned without being a disciple in person. Fei Ying had no selfishness, and did not hesitate to spend her mental power to teach herself the best set of knot spirit array diagrams she had mastered with the method of inscription. This favor, Lu Chen wrote down in his heart. If there is kindness, it will be repaid, and if there is revenge, this is his road!

Immediately, Lu Chen didn't say anything more, turned around and left Fei Ying's Alchemy Peak, and galloped all the way back to the Mine Hall Cave Mansion Peak.

In the cave.

Lu Chen immersed the spiritual power information left by Fei Ying at the center of his eyebrows with the power of knowing the sea, and in less than a cup of tea, he completely analyzed the information contained in Fei Ying's spiritual power and transformed it into his own income.

Fei Ying used the method of spiritual power inscription to leave the knot Dan Spirit Formation diagram, which was like an empowerment to Lu Chen. As long as Lu Chen parses it, it is equivalent to mastering this pair of knot pill spirit array diagrams. The reason why she did not hesitate to spend her spiritual power to pass down the Jie Dan Spirit Array was because she could see that Lu Chen seemed to be eager to succeed in alchemy.

But in Fei Ying's mind, even if she used the method of spiritual power inscription to pass down the Jie Dan Spirit Array Diagram, for Lu Chen, who only cultivated in the Qi Sea Realm, it would take at least ten days and half a month to completely digest this Jie Dan Spirit Array Diagram. After all, it takes time to sense the message of her mental power with her mind, and it takes even more time to slowly parse the message in her mental power. Fei Ying would never have imagined that Lu Chen would open up his own knowledge of the sea and condense the power of knowledge of the sea. Using the power of sea awareness, which is one level higher than spiritual power, to analyze the spiritual power information, the speed is naturally extremely fast.

The Jie Dan Ling Array is a painting composed of countless lines. Each of these lines is a blend of spiritual power and one's own qi. There is nothing peculiar about extracting these lines separately, but when these lines are entangled with each other and condensed together, they reveal strange fluctuations.

Moreover, the Knot Dan Ling Array is not just a painting on a piece of paper, it is a spherical pattern, so it is more difficult to comprehend. If Lu Chen hadn't condensed the power of knowing the sea and comprehended the Jie Dan Spirit Formation Diagram purely with his mind, the time it would take would have increased by a hundredfold.

"Phew!"

A wisp of pale golden true qi escaped from his fingertips, and then the sea knowledge dragon gate opened, and the power of sea knowledge escaped, blending with the true qi. This process is like rolling two threads into one. He carved it in the air with his fingertips, and slowly engraved out the knot pill spirit array with one stroke at a time.

Although he has mastered the Jie Dan Spirit Formation Diagram, it is still a little jerky to really portray it. Fortunately, as time passed, this jerky feeling gradually disappeared.

Half an hour later, Lu Chen was already able to depict the Jie Dan Spirit Array taught by Fei Ying within ten breaths.
