It was late at night when Jiang Li was sent away. Lu Chen pondered for a while the only way to use the Qingguang Sword Technique, but he still had no clue about the swordsmanship skills obtained from the tip of the Qingguang Sword. After a while, pack up your way to the spirit stone mine. At this moment, he already knew that he couldn't use the spirit stones he opened for his own cultivation, so naturally he wouldn't mine the spirit stones in the mine path anymore.

Lingshi Pit.

Lu Chen descended the stone path of the pit ladder and soon came to the entrance of the first mine. He didn't go deep into the mine, but sat in the middle of the mine with his back to the oblique moonlight.

Immediately, his mind moved slightly, and a faint light lit up on his chest, and seventy little gluttons were urged with all their strength to frantically devour the rich fire attribute aura in the mine.

The tunnels in the Lingshi pit are tree-shaped. The passage at the entrance of the mine is like a tree trunk, and the deeper you go into the mine, the more branches in the mine become, like the many branches of a giant tree growing out of the trunk. At this moment, Lu Chen sat at the entrance of the mine tunnel, urging the little gluttony in the sternum with all his strength to devour the fire attribute aura in the trunk mine, and the fire attribute aura in the rest of the branches and branches of the mine path would slowly flow towards the trunk mine, and Lu Chen could devour the fire attribute aura in the entire mine path with patience.

Call~

Bursts of hot wind poured from the depths of the mine, and a cyclone appeared in the sky on a glimmer of light in front of Lu Chen's chest, and the cyclone spun endlessly, engulfing wisps of fire attribute aura.

At this moment, the medicinal power of the Nine Treasure Quenching Body Fluid in the body has already been exhausted, and even if the surging heaven and earth aura is accumulated, it cannot be used to impact and awaken the new little gluttony. Therefore, Lu Chen simply urged the seventy little gluttons in the sternum, intending to incorporate the fire attribute aura in the first mine into his body one by one, and let the fire attribute aura wander freely in the meridians and dantian.

While urging the little gluttonous in the sternum to devour the aura in the mine, Lu Chen separated a wisp of his mind to pay attention to the movements around him. If someone came to the spirit stone pit, he would immediately stop urging the little glutton. Although the fire attribute aura in the Devouring Mine Path was not restricted, Lu Chen did not want to expose his method of cultivating the physical body. Fortunately, it was the day of the stone payment, and it was late at night, and no one else appeared in the spirit stone pit, so he had been devouring the spiritual energy of the mine without distraction.

Time passed slowly, and after Lu Chen had devoured the fire-attribute aura in the first mine, he continued to go down the pit ladder stone road, devouring the fire-attribute aura in each mine-way one by one. Although the fire attribute aura contained in the mine path is quite rich, but after swallowing it up, Lu Chen already has an approximation, and the aura contained in the entire mine path is only equivalent to about one percent of a low-grade fire attribute spirit stone. Fortunately, there are hundreds of caves in the entire spirit stone pit, and after swallowing them, they accumulate a lot, and in the end, it is at least equivalent to devouring more than ten low-grade fire attribute spirit stones.

I don't know how long it has been, after Lu Chen came to the bottom of the pit and devoured the fire attribute aura contained in a mine tunnel, he did not get up and go to the next nearby mine path as before, but sat motionless. At this moment, he had a sense of satiety, and as soon as his mind moved to understand the power of the sea, he looked inside his body, and immediately knew that the meridians and dantian in his body had reached saturation, and even in the flesh and tendons, there were wisps of fire attribute aura swimming. The physical body is like a cup filled with water, even if it urges the little glutton, it can't swallow more fire attribute spiritual energy into the body.

Wisps of fire-attribute aura filled the meridians and dantians, imprisoned by the powerful flesh. If other martial arts monks saw this scene, they would definitely shout that Lu Chen was crazy! Heaven and earth aura that has not been refined into its own true qi, even if it is an attributeless aura, it is also a different kind of true qi, and the different kind of true qi will cause great damage and load to the physical body, meridians, dantian, and so on. Therefore, ordinary martial arts cultivators did not dare to refrain from refining at one time and only devouring so much heaven and earth aura.

Lu Chen has no taboos, awakening seventy little gluttons, his physical body is extremely strong, and he can withstand the breakthrough of the two powerful exercises of the Nine Dragons Proverb and the Divine Sword Qi Cultivation Technique, and it is not a problem to devour the aura of heaven and earth.

However, the physical body was filled with fire-attribute aura, but the sea of qi did not move, and there was no trace of fire-attribute aura that was refined into its own true qi by the sea of qi. As soon as his mind moved, the Divine Sword Qi Cultivation Technique was put into operation, and the sea of qi bathed in the rich fire attribute aura only slowly rotated, as if the wheels were stuck in the mud, and only a very small amount of fire attribute aura was refined into its own true qi by the sea of qi. According to the speed at which Qi Hai was refining the fire attribute aura at the moment, if he wanted to refine all the fire attribute aura devoured into the body into true qi, he would not be able to succeed without ten days and half a month.

"Proverbs of Fire!"

Lu Chen shouted in his heart, running the Nine Dragons Proverb. There was a crackling sound in the flesh, like the movement of a flame burning. Under the inner gaze, the gossamer flames were stripped out of the fire attribute aura that was permeated in the meridians, dantian, flesh and blood, and tendons.

The gossamer flame was very similar to the flame red hairs that were finally formed when the lower grade fire attribute spirit stone was peeled off before, and as soon as the gossamer flame appeared, it swam rapidly along the meridians, and finally all of them were submerged in the sea of knowledge. And as the gossamer flames disappeared, the fire-attribute aura that filled the physical body gradually transformed into an attribute-free aura.

When Lu Chen ran the Fire Proverb to strip off the attributes of the fire aura in his body, he also operated the Divine Sword Qi Cultivation Technique. With the transformation of the fire attribute aura to the non-attribute spirit stone, the speed of the sea of qi gradually accelerated. As soon as the gossamer flame was stripped from the fire attribute aura, the sea of qi absorbed the aura that had lost its attribute and refined it into a wisp of true qi to strengthen the sea of qi.

Waiting for the last gossamer flame to be stripped away, and then the last attributeless aura was also used by Lu Chen to use the Divine Sword Qi Cultivation Technique to urge the sea of qi to refine into his own true qi. Originally, it only took ten days and half a month to completely refine the fire attribute aura that only required ten days and half a month to run the Divine Sword Qi Cultivation Technique, but after it was combined with the Nine Dragons Proverbs, it was refined in less than two hours.

The aura devoured this time was all used for the cultivation of the Divine Sword Qi Cultivation Technique. After sensing it, he noticed that the sea of qi in the dantian had grown a little stronger, and Lu Chen's heart was slightly happy. After not being able to use spirit stones to cultivate, Lu Chen thought of this method for the first time, but he didn't expect it to be feasible.

When cultivating with the lower-grade fire attribute spirit stones, Lu Chen first stripped off the attributes in the lower-grade fire attribute spirit stones, and devoured the non-attribute aura in the refining spirit stones. At this moment, Lu Chen used his physical body as a container, first frantically devouring the fire attribute aura in the mine, and then running the Nine Dragons Proverbs, directly transforming these fire attribute aura into attributeless aura in his own body, and finally using the divine sword qi cultivation technique to urge the sea of qi to refine it into his own true qi.

Lu Chen breathed a sigh of relief in his heart, as long as he didn't delay his cultivation, in his opinion, there was nothing wrong with entering the forbidden mine to mine spirit stones.

Now, only the fire attribute aura contained in the last seven or eight mine tunnels was not devoured by Lu Chen, while the fire attribute aura contained in the rest of the mine tunnels was devoured. After the aura in a branch mine was devoured, it would take several hours for the aura to recover as it flowed between heaven and earth, and Lu Chen estimated that it would take about three or four days for all the aura in these mines to recover.

For the fire attribute aura in the remaining few mines, Lu Chen did not plan to continue devouring and refining for the time being. After finishing his cultivation, Lu Chen slowly opened his eyes. The stars were dotted in the night, and after Lu Chen swallowed a handful of blood pills, he wanted to return to Dongfu Peak immediately, but suddenly his heart moved, and his eyes searched the bottom of the spirit stone pit.

After a while, Lu Chen's eyes lit up, and sure enough, he saw a mine road similar to Jiang Feiyun and Ning Yu's description. In the past month since entering the mine hall, Lu Chen has not even carefully inspected the mine road that Jiang Feiyun and the others are responsible for, let alone the other mine roads in the mine hall.

Taking a closer look at this moment, Lu Chen found that this mine was indeed slightly different from other mines. There will be a stone convex above the entrance of each mine stone cave, which is engraved with special characters: A twenty-seven, C eighteen, Yin thirteen, such as Jiang Feiyun and others are responsible for the mine road is engraved with the word "You Eleven".

At this moment, the mine road in front of Lu Chen, the raised stone above the entrance of the mine only has a "forbidden" word engraved on it, which is unique in the entire spirit stone pit, needless to say, Lu Chen also knows that the mine road in front of him is the forbidden mine road in which he wants to mine spirit stones.

After glancing at the entrance of the mine, Lu Chen immediately prepared to step into the mine to see if this forbidden mine was really as peculiar as Jiang Feiyun and the others said.

At that moment, a slight cough came from the mine.

"Is there actually someone in the forbidden mine?" Lu Chen said in his heart, slightly surprised. Jiang Feiyun and Ning Yu had never mentioned to him in their previous words that there were other mine hall disciples in the forbidden number mine road. However, Lu Chen was sure that he had heard it correctly, it was indeed a coughing sound made by a person. Determining this, Lu Chen paused, took a few steps back, and waited for the person in the forbidden mine to come out.

A moment later, the footsteps were getting closer and closer, and Lu Chen's eyes looked at the entrance of the forbidden mine. At this moment, the moonlight slanted into the mouth of the cave, and a figure gradually walked out.

I saw that the person who came out of the forbidden mine was a thin old man, the old man's face was scattered with patches of old age spots of different sizes, and the old man's two eyelids seemed to be very heavy, so that the eyes could only be half-open and half-closed, giving people a sense of listlessness, and as if he had not woken up, the old man's body revealed a dying breath.

However, even so, when Lu Chen saw the old man for the first time, he inexplicably felt that the old man in front of him had a demeanor that he couldn't see through. It's just the old man's next words that immediately scattered the impenetrable demeanor in Lu Chen's heart.

"Boy, my name is Huo Lao, I opened this mine, if you want to enter this mine, you must first deliver a batch of spirit stones. The old man crossed the hole and stretched out his hand towards Lu Chen and said.
