I don't know how long it has been, no trace of the essence of fire has escaped from the sea of knowledge, and Lu Chen knows that the essence of fire that was previously integrated into his sea of knowledge has been refined.

And as a little bit of the essence of fire was refined and refined from the sea of knowledge, Lu Chen could clearly feel that his thoughts were gradually becoming clearer, the most obvious being that he was no longer obsessed with integrating more essence of fire into the sea of knowledge. This change had nothing to do with Gu Linglong's informing of the harm of the Fire Essence to the Sea of Knowledge, it was entirely because after the Fire Essence was refined, his thoughts were no longer disturbed and returned to normal.

Realizing this, Lu Chen completely relieved himself. Turning his head to look at the back hall of the cave mansion, he saw Gu Linglong's beautiful eyes closed at this moment, sitting motionless on the stone bed, and he was refining the alien true qi he had absorbed from his origin dragon crystal without distraction. Seeing this scene, Lu Chen didn't make a sound, and sensed the Origin Dragon Crystal in his sternum. The Origin Dragon Crystal, which had been drained from all of it, was almost restored to its original state at this moment.

Since the dragon qi in the Origin Dragon Crystal was surging, Lu Chen was not in a hurry to cultivate the Nine Dragons Proverbs. After thinking for a while, Lu Chen uncovered the purple gourd, and looked in through the mouth of the gourd with a large copper coin hole, only to see that the dark red sparks in the gourd flowed slowly like magma and fire liquid, almost filling the mouth of the gourd. Seeing this, Lu Chen's heart moved slightly, there was no need to refine more fire essence at this moment, these dark red sparks could be used to cultivate the flesh body exercises and devour the Heavenly Scriptures.

Refining and destroying the dark red spark and devouring the dark red spark, although the results are different, but the effect is the same, just like Huo Lao continued to say that he could refine and destroy it himself. Thinking of this, Lu Chen put the purple gourd in front of him, and took out a bottle of Jiubao quenching body fluid and opened it in a row.

Withdrawing from his clothes, Lu Chen immersed himself in his mind and exercised his breath for a moment to put himself in the best state of cultivation. Immediately, the mind took advantage of the trend to run gluttonous and swallow the heavenly scriptures, urging the awakened little gluttony in the sternum. In an instant, a glimmer of light lit up from the sternum, and this time Lu Chen was ready to merge into one cultivation, refining the Nine Treasures Quenching Body Fluid, and at the same time, he also devoured the Dark Red Mars to refine the essence of fire in it.

Ice-blue medicinal liquids flew up in the air and extended towards Lu Chen's chest, and at the same time, a stream of flames from the purple gourd also surged towards his chest. In the end, the ice-blue Nine Treasure Quenching Body Fluid and the dark red Spark swirled endlessly, forming a brilliant two-color vortex that disappeared into the glimmer of light.

Lu Chen's physical strength at this moment was not able to resist the dark red sparks, and he needed to put on a layer of true qi cover in advance to resist it. However, the dim red spark did not cause him the slightest discomfort when it entered the glimmer of light in his chest, and so far Lu Chen had not encountered the spiritual energy of heaven and earth that could not directly devour the refining of the Heavenly Scriptures.

The dark red spark was devoured, and the essence of fire in it was refined into wisps of pure energy and integrated into the body, and at the same time, the medicinal power of the Nine Treasures Quenching Body Fluid was also refined into the body. Under the traction of the medicinal power, the surging energy continued to wash over the sternum like a wave, and time passed slowly, and there seemed to be a new gluttony in the sternum about to awaken......

At this moment, being in the cave mansion, Lu Chen didn't have to worry about being disturbed at all, and he had no distractions when he cultivated. Bottles of Nine Treasures Quenching Body Fluid were refined, and the dark red sparks in the gourd were also decreasing, and every once in a while, a small gluttonous awakening in his sternum.

The last bottle of Nine Treasure Quenching Body Fluid was refined, and the dark red spark in the gourd was about to run out, and after another moment, a ray of light suddenly lit up from Lu Chen's sternum. Lu Chen's body trembled slightly, and the eyes that had been closed were also suddenly opened at this moment, and all the ninety little gluttons had awakened, and the gluttonous devouring heaven scripture had reached the first layer - the ice muscle realm!

I saw that ninety faint rays of light in the sternum vibrated and flowed in all directions along a strange trajectory, and after a while, only a glimmer of light was left on the sternum. In Lu Chen's induction, only one little gluttony remained in the sternum, and the rest of the eighty-nine little gluttons all escaped to all parts of the body.

Eyebrows, shoulders, fingertips, soles of feet...... The moment he stepped into the Ice Muscle Realm, the ninety little gluttons that had originally gathered in the sternum moved to all parts of their bodies in a strange trajectory like exploding fireworks, and finally chose a place of flesh and blood to settle, and then one by one the little gluttons slowly sank into the flesh and blood of that place.

Lu Chen's heart moved slightly, he really didn't expect that there would be such a change after he stepped into the Ice Muscle Realm. The power of the sea was mobilized to probe itself, and I saw that the ninety little gluttons scattered all over the body did not settle indiscriminately, but sketched a strange pattern in the flesh. This peculiar pattern seems to contain some kind of truth, but with his current realm, he can't comprehend what secrets are hidden in the peculiar pattern.

Although he couldn't immediately decipher the secrets contained in the peculiar patterns, Lu Chen did not despise them, but imprinted the peculiar patterns deeply into his heart and kept them for future comprehension.

And as the little gluttony sank into the depths of his flesh, a large amount of black goo overflowed from his pores, and these black gooes emitted an unpleasant pungent smell. However, Lu Chen was enjoying it, and his body trembled slightly. The black viscous matter is actually the impurities of the flesh, and as the impurities of the flesh continue to overflow, Lu Chen can feel that his flesh has become stronger than before.

However, thinking that Gu Linglong was also in the cave, Lu Chen hurriedly walked to a stone room. The stone room was a bathroom, and Lu Chen entered it to wash up and change into a clean shirt before returning to the main hall of the cave mansion.

Washing away the impurities of the flesh, Lu Chen's palms were spread out, and he saw that the muscles under the membrane were all crystal clear, like carved from cold ice.

After a closer look, every muscle around his body was like this, and at this moment, Lu Chen's heart suddenly dawned, it turned out that this was the first layer of the Ice Muscle Realm of the Gluttonous Devouring Heaven Sutra! Although the muscles are carved from ice, they are not cold and fragile at all, but full of strength and tenacity.

Lu Chen's body shape did not change much, and with the removal of impurities from his body, he even lost some weight, but at this moment, his body was full of surging power, as if it was endless. Gently clenching his fists, Lu Chen felt the powerful power bursting out of his body. Although his Divine Sword Qi Cultivation Technique was only in the Qi Sea Five Heavens realm, but without using the true qi in his body, with the power of his physical body alone, he should be able to easily defeat the Qi Sea Six Heavens to his stomach.

And as the gluttonous Heaven Swallowing Sutra stepped into the first layer of the Ice Muscle Realm, Lu Chen realized that his Sea Awareness Dragon Gate and Sea Awareness had become more stable. Thinking about it slightly, Lu Chen suddenly realized. The physical body is real, the sea is virtual, the physical body is the foundation of the sea, and the dragon gate is the gateway connecting the physical body and the sea.

After getting used to the strength, Lu Chen looked at the empty bottles and purple gourds all over the ground, and secretly said in his heart that it was a coincidence that this time he awakened the remaining gluttony and cultivated into ice muscles, and he actually used up all the three hundred Nine Treasure Quenching Body Fluid, and there was not much dark red spark left in the purple gourd. This time, if there was a drop less of Jiubao quenching body fluid, or if the dark red sparks in the purple gourd were insufficient, he would not be able to successfully step into the ice muscle realm of gluttonous and devouring the Heavenly Scriptures.

There were still some dark red sparks left in the gourd, and Lu Chen's heart moved, urging a small gluttonous at his fingertips, and at the same time running the gluttonous devouring heavenly scripture, a cyclone immediately appeared on his fingertips. Immediately, a dark red spark rose from the gourd like magma and fire, connecting to the cyclone of Lu Chen's fingertips, and finally disappeared without a trace in the cyclone. At the same time, the heaven and earth spiritual energy contained in the dark red spark was devoured into the body.

After a few moments, the dark red sparks in the gourd were swallowed up. Lu Chen estimated that when he cultivated to the Ice Muscle Realm, his speed of devouring heaven and earth spiritual energy was significantly doubled compared to before.

And after stepping into the Ice Muscle Realm, the medicinal power of the Nine Treasure Quenching Body Fluid could no longer sustain the next cultivation of the Gluttonous Devouring Heaven Sutra, and a new elixir was needed, the Nine Treasure Quenching Bone Pill.

Lu Chen checked it, his brows gradually furrowed, the nine medicinal materials for refining the Nine Treasure Quenching Bone Pill were one grade higher than the nine medicinal materials for refining the Nine Treasure Quenching Body Fluid, and the method of refining the Nine Treasure Quenching Bone Pill did not seem to be simple. Now he is almost penniless, and he doesn't even want to continue to cultivate to a higher realm.

The Qi Sea Realm is divided into four layers: outer, inner, qi, and god, and after cultivating into the Ice Muscle Realm, Lu Chen faintly felt that before he stepped into the fourth layer of the God Realm, he didn't need to worry that his physical body would not be able to withstand the double breakthrough of the Divine Sword Qi Cultivation Technique and the Nine Dragons Proverbs, and without the Nine Treasure Quenching Bone Pill, even if he devoured enough heaven and earth spiritual energy, he would not be able to awaken the new little gluttony, and he was not in a hurry to improve the gluttony and swallow the Heavenly Scripture at present.

With a slight movement in his mind, Lu Chen ran the Nine Dragons Proverbs, mobilizing the essence of fire obtained by devouring the dark red spark to flock to the origin dragon crystal, refining the essence of fire contained in the dark red spark into dragon qi. A moment later, the little dark red spark left in the gourd was also consumed. Fortunately, the Nine Dragons Proverb can also absorb the essence of dark red spark refining fire, otherwise he would have broken his promise to Huo Lao.

Seeing that Lu Chen had finished his cultivation, Gu Linglong turned into a small white jade fish again, swam over and said, "Take me out to breathe." ”

Lu Chen nodded slightly, and he also had plans to go out. Although I don't know how long it has been, the three hundred Nine Treasure Quenching Body Fluid and the dark red sparks in the gourd have been exhausted, and at least ten days have passed, I am afraid that Huo Lao is already waiting in a hurry in the forbidden mine.

"Although I don't know what the strength of the other three halls in the sect is, Elder Fan Sheng in the mine hall is a master of the True Gang Realm, and the fire elder in the forbidden mine is also extraordinary. Lu Chen said.

"Don't worry, as long as I don't use my dragon qi, the Terran monks of the True Gang Realm don't want to find me. Gu Linglong said confidently, and her voice sounded directly in Lu Chen's mind.

Lu Chen nodded when he heard this, and after cleaning up the cave mansion, he stretched out his sleeve towards Gu Linglong, signaling Gu Linglong to sneak into his sleeve.

"Why don't you use the medicine sachet?" Gu Linglong asked in surprise.

After thinking for a moment, Lu Chen explained: "After Tian Gaoluo of Qingxiao Sect took Lin Yue away from the Lin family, the main vein of Tianyang City, I always felt that Tian Gaoluo would find the sect one day. When I was in Qinghe City, the medicine bag was almost inseparable from me, if Tian Gaoluo really found the sect, with his keen mind, he would definitely use this to search for me, and this medicine bag should not be used again. ”

"You're still a little too weak, if you have the ability to overcome Zhengang, even if he finds the Red Fire Gate. Gu Linglong swam into Lu Chen's sleeve and complained.
