This time, all the areas in the first passage had been explored, and the upper echelons of the Flame Sect were killed by Cheng Ling. There are also the two hall masters of Senlong Hall who were killed before, and there are already four people in their hands.

With such feats, coupled with the discovery of the conspiracy of the Flame Sect and the Seven Great Forces, it must not be a big problem to become a core disciple. Bai Yiyi and Gu Youlan also knew that these exploits were still cost-effective for Cheng Ling, and they didn't come forward to fight!

Knowing from the mouth of the Heavenly Wolf Protector that the other three Protectors in the valley were not there, the three of them did not stay longer, and returned to the previous passage hall together.

Cheng Ling looked at the last passage, muttered a little, and said: "Here, this is the last passage, I have an intuition, it must not be simple inside, do you say you want to enter?"

Bai Yiyi grinned, didn't care at all, and said: "Anyway, the first few passages have been entered, and it's not bad like this, let's go in and investigate!"

Gu Youlan just looked at him and didn't speak.

Cheng Ling groaned slightly, and finally decided to go in and explore. Before, the Golden Dragon Hall and the Water Dragon Hall all got a rare opportunity, and the last passage, according to their own speculation, although it was the most dangerous, but the opportunity was definitely the greatest.

After adjusting his state, he took the two girls into the passage and walked towards the depths.

The tunnel was dry, and even the air felt a little hot. The three of them walked forward in turn, and gradually beads of sweat appeared on their bodies. After walking forward for a long time, it only felt hotter and hotter, and at this time, the passage began to extend down again.

The three of them ran the true yuan, resisting the scorching heat in the passage, but fortunately they still held on. Continuing down, I don't know how many journeys I have passed, and finally I saw a portal, and there are four big characters written on the portal, "Hell Lava"!

When we got here, we were already in the ground. The three of them looked at the portal in front of them, only to feel bursts of scorching breath coming, around the portal, there was not a single grass, even the rammed earth on the edge of the portal was burned and cracked.

Bai Yiyi was scared and said: "It's too hot here, I don't know what is in the portal, should we go in?"

What she cultivates is a water-based exercise, which has a certain bonus to the resistance to the scorching heat, but it is always inferior to Gu Youlan and Cheng Ling. Gu Youlan cultivates the ice system, and her ability to resist scorching heat is ten times stronger than her, but Cheng Ling has comprehended the artistic conception of fire, as well as the protection of the water of origin, and her resistance is extremely strong.

Cheng Ling glanced at Gu Youlan and asked, "Senior Sister Gu, what do you see?"

Gu Youlan said indifferently: "I want to go in and have a look!"

Cheng Ling turned her head to look at Bai Yiyi, Bai Yiyi pouted, and said helplessly: "Go in, go in!"

"Okay, then let's go first and have a look, and if we can't bear it, we'll come out immediately!"

The two women nodded, Cheng Ling broke the ban, and the three of them walked in.

As soon as they entered the lockdown, a terrifying heat hit their faces, and the clothes on the three of them were all scorched, and the temperature inside the portal was at least ten times stronger than outside.

The three of them were busy running the exercises, laying a layer of defensive light shield around their bodies, constantly resisting the burning of the high temperature, and looking around.

I saw a huge lava cave in front of me, the whole lava cave was scorched red by the fierce high temperature, and below the lava cave, there was a large pool of dense magma, and fiery red bubbles rose in the pool water, and the gurgling sound was non-stop!

On the ground, dark red magma gushed out in the billowing black smoke, and after tens of thousands of years of accumulation, it formed narrow passages

(This chapter is not finished, please turn the page)

, dividing the entire magma pool into densely packed hundreds. In the depths of the lava cave, there is a faint appearance of several square secret rooms.

The temperature in the lava cave was extremely high, and the true yuan was consumed too quickly, so Cheng Ling hurriedly swallowed an elixir to restore the true yuan in his body. But in less than a moment, those true elements were instantly evaporated, leaving only a small trace, but that trace of true yuan was much purer than its own.

His heart moved, could it be that there was a function of refining the purity of the true element? Swallow an elixir again, refine it, and look at himself. It was found that the majestic aura in the elixir had been evaporated in the process of refining, leaving only the purest trace of it.

This trace of true essence cannot be refined by the scorching high temperature, and the purity has reached the limit. He was overjoyed, and he couldn't imagine that there would be such benefits here.

The true essence of the monk is derived from the absorption and transformation of the aura of heaven and earth. During the transformation process, the impurities in the aura of heaven and earth were not removed, and there were many residues in the body. This is also a major reason for the disparity in combat power between monks of the same level.

If you want to exert the maximum power of the true element, you can only purify your own true element after reaching a certain level of cultivation. Therefore, many monks who have reached a certain realm cannot break through in time, and they cannot exert the full power of swordsmanship and martial arts, just because the true yuan is not pure enough.

True element purification is a long process, which often requires water grinding to remove impurities, and it takes a long time. Especially after arriving at the Jindan, the total amount of the monk's own true yuan will be greatly enhanced, and correspondingly, the time for purification will also be greatly increased.

Moreover, this kind of purification has high requirements for exercises, and the higher the grade of exercises, the stronger the effect of purification. Just imagine, a low-level exercise at the ground level, the meridian route required to carry Zhou Tian is definitely not as good as the exercises at the top of the ground level. As a result, each purification takes longer.

The true element circulates in the muscles and veins in the body, and is finally injected into the dantian. The more complicated the exercise transportation route, the more true elements will be purified. On the contrary, if someone moves one circle, you need to carry several times. In this way, the gap arises, and the higher the cultivation, the greater the disparity.

What's even more troublesome is that this kind of purification can rarely make use of external objects, only some rare heavenly treasures and heavenly fires can help the monk increase his speed. The lava cave in front of him was discovered by the Fire Ancestor by chance and used to purify the true element.

"No, I can't stay here, and if I stay any longer, I won't be able to see anyone. Bai Yiyi said bitterly.

Cheng Ling turned her head to look, only to see that the clothes on Bai Yiyi's body were scorched by the high temperature in the molten cavern, showing a black and gray color, many of them had turned into ashes, and most of the skin on her body was exposed. Seeing Cheng Ling turn his head, he hurriedly scolded: "Villain, don't look back!"

Cheng Ling secretly praised this chick for being really expected, and glanced at Gu Youlan with both eyes. Unfortunately, the latter was neatly dressed, as if the heat in the cavern had no effect on her.

Sharp! Sure enough, it is a peerless iceberg, even clothes have this attribute!

Laughing and laughing, Cheng Ling knew that it must be because of Gu Youlan's cultivation technique, the top-level technique of the pure ice system was much stronger than Bai Yiyi's. Don't you see that the clothes on your body are also starting to dissipate?

He held out his finger and pointed it towards his forehead. A drop of water emerges and slowly floats in mid-air.

"Go!"

The water droplets instantly submerged into Bai Yiyi's body, and gradually, a blue liquid shield formed around her, scorching

(This chapter is not finished, please turn the page)

The temperature has slowed down a lot.

"Water of the Origin!"

Bai Yiyi looked at Cheng Ling in surprise and asked, "Brother Ling, you actually have the water of the origin." ”

"Well, I got it in the Water Dragon Hall, and it's just right to use it here. You can carry the exercises and see, although the scorching heat here is unbearable, it is very helpful for the purification of the true element. ”

Bai Yiyi was overjoyed and said: "Thank you, this source water just allows me to comprehend, and it can also enhance the perception of the artistic conception of water." ”

Gu Youlan also said: "I can too!"

The ice system is a branch of the water system, and there are also changes in the ice system in the water of the origin. For Gu Youlan, using the water of origin to enhance the artistic conception of ice is like looking at each other through a veil, although it is not direct enough, but it is also effective.

Cheng Ling nodded and said, "Then you first comprehend the artistic conception, and I will first mention the pure true element." ”

The two girls nodded, and Bai Yiyi divided half of the water of the origin and let Gu Youlan understand. But her point is not enough. This drop of origin water was already incomplete, and after such a point, the enveloped area was greatly reduced, and most of the clothes on Bai Yiyi's body turned into ashes.

She let out a scream, and hurriedly stopped the differentiation of the Origin Water, and the only parts that could be covered were her chest and lower abdomen. She shouted loudly, "Brother Ling, don't look over!"

Cheng Ling's eyes lit up, laughed, and said, "Sister Yiyi, your figure is good, and you look better now!"

However, he didn't keep staring, knowing that this girl's face was tender, he laughed, so he turned his head and sat down cross-legged, and began to refine the true yuan.

Bai Yiyi's little face was flushed, and when she heard him laugh, her heart was sweet, and she secretly thought to herself, does he like me to dress more revealingly? Only Gu Youlan's face changed, the qi and blood in his body surged, and he almost spurted out a mouthful of blood, busy running the exercises, and forcibly suppressing it.

After such a fuss, the relationship between the three of them became even more ambiguous. When the two women saw Cheng Ling turn around, they also calmed down, sat down cross-legged, and began to comprehend the artistic conception in the water of the source.

Time passed slowly, and the circle of the true element in Cheng Ling's body, and the high temperature in the molten cavern continued to burn the impurities in the true element. Later, his Yuan Infant began to become pale, and the consumption of True Yuan was too great, although the purity of the essence was improved, the total amount was reduced, and it was in urgent need of replenishment.

He took out the Xuanyuan Pill to replenish the spiritual power in his body. The auxiliary cultivation of the pill was also greatly weakened at this moment. In itself, there are many impurities in the pill, even if it is the best pill, there are still a lot of impurities.

Therefore, if a monk relies on pills to improve his cultivation for a long time, he will reduce the purity of his true element, his power will be greatly reduced, and his realm will be unstable. This is also one of the reasons why the family ascetic monks are not as powerful as monks who have been training outside for a long time.

With each Xuanyuan Pill, the True Yuan replenished was greatly weakened, only less than one-tenth of the usual amount. His dantian was like a lake filled with true yuan, and the water level in the lake had dropped below half.

However, this is less than half of the true element, the purity of the essence is too different, in the past, looking at itself, the true element in the dantian has some very fine particles, which are obviously impurities. Looking at the current Zhenyuan liquid, it is pure, completely transparent, and there is hardly a single particle, which is already pure to the limit.

It's just that correspondingly, his cultivation has also dropped to the middle of the Yuan Infant Stage, a whole small realm lower.
