The next day, early in the morning.

Jiang Feiyun and the others came to Lu Chen's cave and took him to the spirit stone pit to continue mining spirit stones, Lu Chen, as always, seemed to throw the scene he saw last night out of the clouds.

Soon, Lu Chen followed everyone into the depths of the mine and came to the mine road he was responsible for. It took more than two hours for Lu Chen to complete the mining of the ten spirit stones stipulated every day.

After a little trimming, Lu Chen continued to mine spirit stones, because he had learned from the past, this time he mined ten spirit stones before stopping. These ten spirit stones will be used for his own cultivation!

It's just that after the ten spirit stones were mined, Lu Chen didn't rush to run the gluttonous devouring heavenly scripture and urge the little gluttonous gluttonous in the sternum to devour the spiritual energy in the refining spirit stone, but secretly thought about it. Now, as long as the Nine Treasures Quenching Body Fluid can be continuously followed, the cultivation of gluttonous Devouring Heavenly Scripture will not be a problem at all.

However, the cultivation of the Divine Sword Qi Cultivation Technique gave Lu Chen a bit of a headache, and the breakthrough of the Divine Sword Qi Cultivation Technique in the Snow Dragon Mountain caused the dragon qi in the barren stone to run wild, and finally made Lu Chen condense the Origin Dragon Crystal in the sternum. Therefore, Lu Chen knew that once the realm of the Divine Sword Qi Cultivation Technique had broken through, the Nine Dragons Proverb could be improved accordingly.

Originally, Lu Chen's cultivation of a realm technique was just to cover up the Nine Dragons Proverbs, but he didn't expect that the Divine Sword Qi Cultivation Technique obtained from the tip of the Qingguang Sword could actually make the Nine Dragons Proverbs improve quickly, which could really be said to be unintentionally inserted into the willows. At this moment, although the entire Red Fire Gate was filled with a rich aura, these auras were fire attributes, and they were repelled by the sea of qi in Lu Chen's body, so cultivating the Divine Sword Qi Cultivation Technique was half the effort.

Every time Gu Linglong woke up, the dragon qi he needed would increase a little. Although the accumulated cultivation can improve the Nine Dragons Proverbs, it is really a world of difference compared to the improvement brought by the breakthrough of the Divine Sword Qi Cultivation Technique. Since cultivating the Divine Sword Qi Cultivation Technique can greatly improve the Nine Dragons Proverbs, Lu Chen naturally will not be reluctant to seek the near and far.

While pondering, Lu Chen rubbed the ten lower-grade fire attribute spirit stones in his hand. Looking at the crystal-colored orange-yellow spirit stone that was churning in his hand, a flash of light flashed in Lu Chen's mind.

The lower grade spirit stones are about the same size as the thumb nail shell, and according to the different attributes of each one, there are only slight differences in color, the lower grade spirit stones without attributes are generally off-white, the lower grade spirit stones with fire attributes are generally orange-yellow, and the lower grade spirit stones with earth attributes are generally dark yellow......

And because the spirit stone has aura, its value far exceeds that of ordinary stones. But when the spiritual energy contained in the spirit stone was absorbed and refined, the spirit stone that was originally of extraordinary value was not even as good as the most ordinary stone. All kinds of spirit stones with different attributes are actually similar to martial arts monks.

Only mortals with innate spiritual roots are eligible to become martial arts cultivators. With a spiritual root, and then cultivating a realm technique, and condensing your own qi sea, you can become a martial arts cultivator. However, martial arts monks can also scatter their exercises and re-practice their exercises, so that they can carry different powers with different exercises.

The realm exercise is equivalent to the attribute, and so on, if the fire attribute in a fire attribute spirit stone is stripped away, then the original fire attribute spirit stone will become a non-attribute spirit stone. Lu Chen sorted out the thoughts that flashed in his heart little by little, and finally came up with a guess that made him feel reasonable.

However, guessing is only speculation after all, and even the most perfect guess is useless if it cannot be realized. Stripping off the attributes in the spirit stone, just thinking about it makes Lu Chen feel that this is definitely not a simple matter. However, Gu Linglong doesn't know when she will wake up, and the Nine Dragons Proverbs must be improved.

Although Lu Chen sensed that it was not a simple matter to strip the attributes in the spirit stone, he did not intend to retreat, and his clear eyes revealed a hint of eagerness. Staring at the ten lower-grade fire attribute spirit stones in his palm, Lu Chen fell into deep thought.

Time flew by, but Lu Chen had no clue. I don't know how long it has passed, and he suddenly thought of something inexplicably, since there is fire in the fire attribute aura, and there is also fire in the fire proverbs in the first part of the Nine Dragons Proverbs, maybe there will be different changes when the two are combined.

As soon as this thought turned, Lu Chen shook his head and laughed for a while. I really wanted to strip the attributes in the spirit stone and wanted to go crazy, and it was really crazy enough to forcibly associate the fire attribute aura with the fire proverb, the first part of the Nine Dragons Proverbs, just because of the word "fire".

The Nine Dragons Proverb is a genuine dragon clan exercise! Thinking of this, Lu Chen was ready to eliminate the thoughts that flashed in his heart. And at this moment, Lu Chen's heart suddenly moved slightly, anyway, he had no clue, so it was better to give it a try. After making up his mind, Lu Chen no longer hesitated.

Grabbing a low-grade fire attribute spirit stone, his mind moved, and the first part of the Nine Dragons Proverbs, the Fire Proverbs, came into operation.

Don't absorb the aura contained in the refining spirit stone, only strip off the attributes in it!Lu Chen closed his eyes, kept his heart clear, and at the same time ran the fire motto, letting his thoughts firmly control the operation of the exercises, and at the same time trying to strip the attributes of the spirit stone. However, Lu Chen didn't have any expectations, the attributes were ethereal, and where they would be easily stripped away.

I don't know how long it took, Lu Chen's only felt a sudden burst of heat in his palm, and then this heat went all the way up the meridians in his arm, and finally disappeared without entering his eyebrows. All of this is slow, but it all happens between lightning and fire.

The sudden appearance and disappearance of a burst of heat made Lu Chen suddenly wake up from the operation of the Fire Proverb, what happened just now? Although he had operated the Fire Proverb, he had not really absorbed the refining spiritual energy from the lower grade fire attribute spirit stone, how could there be a burst of heat that drilled into his body, and even disappeared without a trace in the center of his eyebrows.

Lu Chen spread out his palms, looked down, first lost his mind slightly, and then suddenly revealed a touch of surprise in his eyes.

He's been running the Proverb of Fire and doesn't have time to steal the beams. And in his hand, it should have been an orange-yellow lower-grade fire attribute spirit stone with a crystalline color and abundant spiritual energy, but at this moment, in his palm was an off-white spirit stone - similar to a low-grade spirit stone with no attributes!

Seeing this scene, how could Lu Chen not know that his previous idea was really feasible! Just because the Fire Attribute Spirit Stone and the Fire Proverb both had a fire character, and linking the two together, Lu Chen just didn't want to give up easily, so he gave it a try, and he didn't have much expectations at all, but the truth was beyond his expectations.

After a while, Lu Chen calmed himself down from the surprise, at this moment whether the beige spirit stone in his palm is a low-grade non-attribute spirit stone remains to be verified, if so, it is naturally worth a surprise, if not, then he can't be happy too early, and he needs to find another way.

Thinking of this, Lu Chen's outstretched palm was clenched again, and with a movement of his heart, the Divine Sword Qi Cultivation Technique was activated, and the sea of qi in the dantian also moved.

Aura with special attributes will only be born in some special heaven and earth, such as the fire attribute aura in the Red Fire Gate at this moment.

The reason why the Red Fire Gate is surrounded by a strong fire-attribute heaven and earth aura is because the underground of this place has fire-attribute spirit stone veins. In Qinghe City, there is no fire attribute aura, and the aura of heaven and earth around Qinghe City is an aura without special attributes.

So far, Lu Chen has only been exposed to two kinds of aura, the first one is the attributeless aura in Qinghe City, and then the fire attribute aura in the Red Fire Gate. Lu Chen didn't know if the Divine Sword Qi Cultivation Technique was equally exclusive to other special attribute aura, but it was certain that the Divine Sword Qi Cultivation Technique did not exclude attribute-free aura.

The Divine Sword Qi Cultivation Technique was put into operation, and the spiritual energy contained in the beige spirit stone poured into the dantian qi sea one after another along Lu Chen's meridians. After a while, Lu Chen's eyes lit up slightly, and the sea of qi did not reject it, but followed his mind to refine the spiritual energy in the spirit stone, refining wisps of spiritual energy into his own true qi. The off-white spirit stone is indeed a non-attribute spirit stone!

Lu Chen did not stop the operation of the Divine Sword Qi Cultivation Technique, continued to absorb the spiritual energy in the spirit stone, and then refined the spiritual energy absorbed into his body into his own true qi.

After another moment, a slight cracking sound came from Lu Chen's palm. The spiritual energy in the spirit stone was refined, and the spirit stone was shattered into a mortal stone. Hearing this shattering sound, Lu Chen's heart was clear, from a low-grade fire attribute spirit stone to a non-attribute spirit stone, the aura contained in the spirit stone has not decreased, and it is still a low-grade spirit stone.

After confirming this, Lu Chen was overjoyed, but then he became puzzled. Turning a low-grade fire attribute spirit stone into a low-grade non-attribute spirit stone, the aura contained in the spirit stone did not change in the slightest, but he clearly noticed that a heat was leaking out of the spirit stone, and then passed through the skin and skin membrane in his palm, and then followed the meridians in his arm, and finally disappeared into his eyebrows.

What was that enthusiasm before? Lu Chen immediately checked the sea of knowledge, but he didn't find anything abnormal. Frowning slightly, Lu Chen casually threw aside the gravel in his palm, and immediately took out one of the remaining nine lower-grade fire attribute spirit stones. His mind moved slightly, and the fire proverb came into play, this time Lu Chen neither closed his eyes nor clenched his palm, but his eyes were firmly fixed on a low-grade fire attribute spirit stone in his palm.

At the same time, a mist-shrouded, divine and majestic portal appeared at the center of his eyebrows, which was the Dragon Gate of the Sea of Knowledge. As soon as the Sea Awareness Dragon Gate appeared, it slowly opened, and a wisp of sea knowledge power probed into the inside of the spirit stone.

As soon as the fire proverb was put into operation, I saw an astonishing change in a low-grade fire attribute spirit stone in the palm of my hand. Although the color of the spirit stone is still crystalline, the orange and yellow color in it is a little condensed and condensed. It is like reversing the process of spreading a drop of ink into water, the diffused ink recondenses, and the ink becomes a glass of water again.

The orange-yellow color in the spirit stone continued to gather, and finally condensed into a hair-like existence. The hairs were flame-red, and after condensing, they immediately disappeared into Lu Chen's palm with the operation of the fire motto, and then went all the way up the meridians in his arms, and finally disappeared into the center of his eyebrows, and at the same time, the previous heat escaped from the flame-red hairs.
