Although he was able to engrave the Jie Dan Spirit Formation with his own true qi and the power of sea knowledge within ten breaths, Lu Chen was not complacent because of this. With the speed at which he was now carving the Jie Dan Spirit Array, it was still too slow. Unless the inscription is completed in advance, even if a mortal-level alchemist is observing his alchemy process from the sidelines, he can see through his knot spirit array diagram at a glance.

And when Fei Ying was refining the elixir, even a higher-level Xuan-level alchemist couldn't see through Fei Ying's knot pill spirit array. However, Lu Chen would only refine the Nine Treasure Quenching Bone Pill in his own cave mansion, so for the time being, he didn't have to worry about Fei Ying's knotting pill spirit formation that was spied on.

Lu Chen thought for a while and made a decision in his heart. Ten breaths is a watershed, and the Ten Breaths are engraved with the Knot Dan Spirit Formation Diagram, which can be regarded as reaching the bottom line of a mortal-level alchemist to engrave the Knot Dan Spirit Formation Diagram. Next, while refining the Nine Treasure Quenching Bone Pill, he also increased his speed of inscribed the Jie Dan Spirit Formation Diagram.

"Bang. ”

A wisp of true qi poured into the storage bracelet, Lu Chen turned over his hand and took out the bronze alchemy furnace and a medicinal material for refining the Nine Treasure Quenching Bone Pill, and then he cast a flame dragon, lingering towards the bronze alchemy furnace, and began to refine the Nine Treasure Quenching Bone Pill.

Snow Huazhi, Zhenguang Ginseng, Water Cloud Fruit, Wind Bone Wood ...... The nine medicinal materials used to refine the Nine Treasures Quenching Bone Pill were put into the bronze alchemy furnace one by one. As the alchemy progressed, the temperature in the cave also rose rapidly. Although the previous dozens of Nine Treasure Quenching Bone Pills had failed to be refined, Lu Chen had not found nothing, and he had been able to urge the Flame Fire Dragon to refine the Pill.

Soon, the refining of a furnace of Nine Treasure Quenching Bone Pill was nearing the end, and it was the most critical moment to tie the pill.

Lu Chen's expression moved, when he was refining the Nine Treasure Quenching Bone Pill before, it was at this moment that the situation suddenly became worse. Even if he controlled the fire with his heart and stabilized the medicinal liquid in the bronze alchemy furnace, it would still be useless, and the alchemy would eventually fail. And although he noticed something abnormal before, he didn't know that it was because of the lack of the Jie Dan Spirit Formation Diagram.

Now he knew what to do, and how to let the refining of this furnace of elixir end in failure. It must be completed within ten breaths of the inscription of the knot spirit array. His fingertips either flicked, or drew a wave trajectory, or volleyed out a regular circle, and the silk thread that combined the power of the sea and his own true qi gradually showed a delicate spherical pattern under the outline of his fingertips.

After a while, the inscription of the Jie Dan Spirit Array was completed, and the Jie Dan Spirit Array inscribed with its own true qi and pure sea knowledge power showed a pale golden luster, like a beautifully carved gold hollow ball.

"Dan Ling unity, seal!"

Lu Chen snorted lightly, and the Formation of the Formation of the Dan Spirit Formation flew towards the bronze alchemy furnace, penetrating the wall of the Dan furnace and falling into the center of the bronze alchemy furnace. The bronze alchemy furnace spun rapidly, and the flame dragon became even more ferocious and furious. In the bronze alchemy furnace, the knot pill spirit array is like a beam frame, and the colorful medicinal liquids rotate and converge into it, and many medicinal liquids undergo more bizarre changes in the knot pill spirit array......

After a while, the bronze alchemy furnace slowly fell back into his hand, and after unveiling it, Lu Chen glanced inside, feeling slightly depressed in his heart. As the so-called talk on paper is shallow, I never know that this matter must be done. While controlling the fire, he controlled the bronze alchemy furnace at the same time, and he also had to be distracted to engrave the Jie Dan Spirit Formation Diagram, which was really not an easy task. Although the inscription of the Jie Dan Spirit Array was completed, it still exceeded the time limit in the end, resulting in the failure of refining this furnace Nine Treasure Quenching Bone Pill.

Not discouraged, after experiencing the alchemy process just now, after about a cup of tea, Lu Chen began to refine the second furnace of Nine Treasure Quenching Bone Pill. Time passed in a hurry, and the second furnace of Nine Treasure Quenching Bone Pill still failed to be refined.

......

I don't know how long it took, and the refining of a furnace pill failed. When the bronze alchemy furnace slowly fell into Lu Chen's hands again, and after it was uncovered, a dragon's eye was large, and the whole body was emerald green, like an emerald gemstone elixir came into view. However, although this pill is in good condition, there is neither a brilliant Danxia nor a refreshing Danxiang on it, and it is obviously just a low-grade pill.

Glancing at the Nine Treasure Quenching Bone Pill, Lu Chen shook his head and smiled, it seemed that when refining the Nine Treasure Quenching Bone Pill for the first time, the Fire Spirit Marten and the Fire Essence really played a key role. He was now barely able to complete the inscription of the Formation Diagram within ten breaths, but the Nine Treasure Quenching Bone Pill he had refined was the lowest-grade Nine Treasure Quenching Bone Pill. But he faintly knew that with the increase in the speed of the inscription of the Jie Dan Spirit Array, the grade of the Nine Treasure Quenching Bone Pill would also improve.

Lu Chen indulged in refining the Nine Treasure Quenching Bone Pill, and time passed unconsciously.

At a certain moment, another set of knot pill spirit array diagram was about to be inscribed, and suddenly, he felt dizzy and swollen, as if the world was spinning, and a feeling of nausea welled up in his heart. He suddenly understood that this was a sign that the power of sea knowledge was overdepleted.

It takes the power of sea knowledge to use the Flame Fire Dragon, and it also takes the power of sea knowledge to engrave the Formation of the Formation of the Formation of the Spirit. The breeding of the power of sea knowledge in the sea can no longer keep up with the speed of his consumption, and over time, the loss will naturally become bigger and bigger, until the new power of sea knowledge has not yet been born, and the old power of sea knowledge has been exhausted.

"Boom!"

The power of knowing the sea was exhausted, the flame dragon also withered, and the Jie Dan Spirit Array, which was already about to be completed, completely collapsed after a burst of light, turning into a little bit of pale golden spiritual light and escaping into the void air. There was a sudden roar in the bronze alchemy furnace, and the refining of this furnace of Nine Treasure Quenching Bone Pill failed.

Lu Chen suppressed his dizziness, paid attention to the sky outside the Lower Cave Mansion, and then swallowed three handfuls of blood pills, and fell asleep on the spot. He didn't have any elixir on his body that was specifically used to restore the power of the sea of knowledge, so he could only use the most primitive and simple method of sleeping to restore the empty sea of knowledge.

Time passed quietly while he was asleep, and when Lu Chen opened his eyes again, he glanced at the outside of the cave through the bronze mirror, and the sky outside the cave was bright at this moment. Obviously, it was the next day, but it was still early before the Shen Shi agreed with Feng Shui Han. After induction, the power of knowing the sea in the sea is full again.

After sorting out the clues, Lu Chen continued to refine the Nine Treasure Quenching Bone Pill. Whenever he refined a low-grade Nine Treasure Quenching Bone Pill, he would deliberately stop and take a short rest, so as not to consume the power of the sea too violently. He had refined dozens of lower-grade Nine Treasure Quenching Bone Pills, and there was still more than half an hour before Shen Shi.

Lu Chen completely stopped alchemy, and devoured three more blood pills, recovering the consumed physical strength and true qi while recovering the consumed power of sea consciousness through meditation.

When Shen was approaching, he quickly cleaned up and rushed to the medicine hall with a heavy gun.

When he arrived at the barren mountain of the medicine hall, Feng Shui Han was sitting cross-legged on a stone and cultivating. Seeing Lu Chen coming over on time, Feng Shui Han's eyes revealed a touch of excitement. In yesterday's battle, he gained a lot, as long as he insisted on practicing with Lu Chen, in front of the sect competition, the power of his sword rhyme could be increased by at least two percent.

"Fight!" Feng Shui Han drew his sword out of its sheath, escaping with an incomparable edge.

"Fight!" Lu Chen was high-spirited, standing with a gun, not moving like a mountain, his eyes were staring at the wind and water.

The two have a very tacit understanding, there is no nonsense, although it is not a life-and-death battle, but the battle is white-hot in an instant. When the figures of the two were staggered, the green and faint sharp sword qi and the pale golden domineering spear collided, shattered, and annihilated on the barren mountain, outlining an incomparably gorgeous scene.

Time flies in battle.

That's it for today. Before an hour came, Feng Shui Han hurriedly shouted, looking at Lu Chen with a strange look in his eyes. At this moment, Feng Shui Han's true qi has been exhausted, and Feng Shui Han can see that Lu Chen's true qi has also been exhausted, but Lu Chen is still full of dragon spirit and tiger spirit.

"You can't beat you hard. Feng Shui Han said depressedly. After the true qi was exhausted, even if he was still blessed by a powerful sword rhyme, he was still crushed by Lu Chen with pure physical strength. He was completely at a disadvantage in the eleventh heaven of the sea of qi, and was crushed by Lu Chen, who only had the nine heavens of the sea of qi, and Feng Shui Han felt indescribably aggrieved in his heart.

"Maybe I ate a little too much blood pill before I came. Lu Chen responded with a smile. If it weren't for the fact that he had been refining the Nine Treasure Quenching Bone Pill before, with his majestic true qi, Feng Shui Han would have made a reckless attack with all his might, and he would definitely have run out of true qi first, but just now he was running out of true qi at the same time as Feng Shui Han.

Feng Shui Han was speechless for a while, if the Blood Pill had such an effect, then he would have to eat dozens of Blood Pills a day. Then he retracted his sword intent, looked at Lu Chen, looked at Lu Chen, and said, "Senior Sister Ling has obtained the Blood Plum Tree Leaf, and now she is refining the Thunder Bead in the Jingtang Cave Mansion, and at the same time, she is also impacting the Second Heaven of the True Gang Realm. ”

"Why did you suddenly tell me this?" Lu Chen was slightly surprised.

After thinking for a while, Feng Shui Han said slowly: "Every year there will be a battle in the sect competition, in the past, there were only miscellaneous disciples in the mine hall, but there were no inner and outer disciples, but this year is different. Feng Shui Han glanced at Lu Chen and continued: "The fourth hall of the sect, you are the only inner disciple of the mine hall, you must be indispensable in the hall battle of this year's sect competition, it will not hurt you to know the strength of the other three disciples in advance." ”

Lu Chen nodded slightly, his identity was indeed a little special, and he was the only inner disciple of the mine hall. Even if Feng Shui is cold, Lu Chen is also mentally prepared.

Feng Shui Han said again: "Senior Sister Ling, Xia Yangtian and Younuo of Dantang, counting me, will be a strong contender for the first place in the sect competition this time." Now, of course, add you as a demon. If you are now the Eleventh Heaven of the Qi Sea, I am even sure that even Xia Yangtian is not your opponent, and the first place in the sect competition is none other than you!"

"It's a pity that your realm is still too low, only the Nine Heavens of the Qi Sea. Feng Shui Han shook his hand, and a touch of helplessness flashed in his eyes. Even if through practice, the power of his sword rhyme will be improved, but in the sect competition, I am afraid that he may not be able to really defeat Xia Yangtian and win the first place in the sect competition.

Lu Chen smiled indifferently at Feng Shui Han's part of talking about himself, and then he looked at Feng Shui Han and asked in surprise. "Senior Brother Feng, looking at your appearance, it seems that Xia Yangtian will win the first place in the sect competition, and you don't seem to want to see Xia Yangtian win the first place. ”
