The night of the Fourth Realm is extremely dark.

Because there is no sun, moon and stars all year round, and there is no natural light source, after night in this realm, wild beasts will refrain from preying.

After working for a long time, the people decided to rest for one night and stayed away from the phoenix bone in the worm valley.

Because of the surrounding area of the phoenix bones, there are many bones scattered by the explorers of the Ouyang family, and in such a deep night, there are piles of dry bones accompanying their sides, and most people will not get used to it.

Pang Jian didn't care.

He didn't light a lamp or light a fire, next to the phoenix bone that pierced into the hive, and sat cross-legged.

"Ning Yao" was very knowledgeable, she smiled softly, and then turned around and left gracefully.

This is the recent tacit understanding between the two.

Pang Jian, who was sitting on the phoenix bone, saw those people from the Su and He families, meditating on the fire at the other end of the Worm Valley.

In the dark night, everyone's vision was limited, and when he felt that Su Yuntian and He Rong couldn't see him, he took down the bamboo basket behind him.

After taking a breath, he calmly cleared the distracting thoughts in his mind and quickly entered the state of cultivation.

This time, he actually gave birth to a wonderful illusion that his perception had been greatly improved.

He intuitively felt that his dantian spiritual sea was divided into two layers, just like the world he was in.

He didn't use the spirit stone in his hand in a hurry, but tried to absorb the mixed heaven and earth aura in the worm valley, and gradually felt that the aura that escaped into his body was on the upper layer of the dantian spirit sea.

The aura is like a cluster of clouds in the upper layers.

When he was running the "Hutian Qi Nourishing Technique", he noticed that between the upper and lower levels, a huge whirlpool suddenly appeared.

The vortex took on a funnel-like shape, connecting the upper and lower layers of the dantian spiritual sea, and the vortex gently rotated, slowly absorbing the cloud-like aura of the upper layer.

As the whirlpool rotated in circles, it continued to refine the aura, sinking towards the bottom of the funnel, and gradually extracted into ...... Spiritual power.

In the lower layer of the dantian spiritual sea, wisps of spiritual power slowly converged, gradually becoming a small pool.

At this time, Pang Jian's heart moved, and he immediately knew the complete layout of the dantian spiritual sea, and also realized that this mysterious little world inside the human body seemed to be two layers.

The reason why it is called the Dantian Linghai is because the upper part is the Dantian, and the place where the spiritual power below gathers is the Linghai.

The dantian and the spiritual sea are connected by a funnel-shaped vortex, and the dantian washes and purifies the spiritual energy and other energy that is inhaled from the outside world, and then condenses it into spiritual power and merges it into the spiritual sea below.

With this understanding, Pang Jian absorbed the mixed aura of the Fourth Realm in the Worm Valley, and carefully felt the wonder of the dantian spiritual sea.

After a while, he suddenly felt as if many mosquitoes, flies, insects, and bees were "buzzing" from all directions, as if they were about to eat him.

Before he was awakened, he saw that those so-called mosquitoes, flies, and insects were all strange powers hidden deep in the aura.

The tiny beings who died in the Worm Valley due to the phoenix bones and were sucked into the essence of flesh and blood, their remnant soul spirits were integrated into the aura, and they were inhaled into his body by him with the "Hutian Qi Nourishing Technique".

When the aura in the Worm Valley was purified by him by the whirlpool, he needed to grind away the mosquitoes, flies, and insects first.

This step is called eliminating dross, and it actually consumes more time, and there is not much spiritual power extracted from it.

After hesitating for a moment, he took out the two spirit stones that were scavenged from Jin Yang, Xu Rui, and the man wearing the mask.

The two spirit stones were shaped like white jade, one of them had sporadic impurities, and the other was extremely pure.

He tried to absorb a spirit stone with impurities, and immediately felt that what was absorbed from the spirit stone in his hand was spiritual power containing a small amount of filthy power.

This is not a cloud-like "qi", but a spiritual power that is consistent with the power in his spiritual sea, like flowing water.

It's just that the spiritual power in it contains some impurities, which need to be purified by the whirlpool connecting the dantian and the spiritual sea, and the impurities in it must be wiped out and melted.

Even so, through a piece of such a spirit stone, the spiritual power he could harvest far exceeded the so-called spiritual energy in the Worm Valley.

It's more than 10 times faster.

Although both sides have impurities and pollution, aura and spiritual power are two concepts at all, and ten times the aura seems to be able to refine a wisp of spiritual power.

And the spiritual power in the spirit stone is existing, and he doesn't need to refine it over and over again, just remove the impurities in it.

Pang Jian, who was in the dark night, opened his eyes slightly, looking at the spirit stone with many spots in his hand.

He finally knew why Jin Yang and the others only carried these Fourth Realm spirit stones in addition to their usual utensils.

With the existence of these spirit stones, those few people could quickly regain their strength, far faster than if they were swallowing the spiritual energy in the Cen Lin Mountain Range.

"Pure spirit stones, what should they be?"

Thinking like this, he looked at another pure and immaculate spirit stone.

This spirit stone came from Ning Yao's leather bag, and it belonged to the remnants of the Blood Moon powerhouse in the "Undetermined Ferry".

He tried to absorb the spiritual power in it, and his eyes suddenly burst into essence.

The spirit stone from the third realm, which did not contain a trace of impurities, was incorporated into the dantian above by him, and slid directly down the funnel-shaped whirlpool, merging into his spiritual sea!

There is no need to quench and wash impurities, there is no need to refine again, and it will immediately become a part of the spiritual sea!

The efficiency and speed of this kind of spiritual power enhancement are several times higher than cultivating with those impure spirit stones!

"No wonder, after she got this thing on the Wuding ferry, it was like a treasure."

Due to the improvement of his perception, Pang Jian was able to intuitively feel the condition of the Dantian Linghai in this cultivation, which was much more thorough than the last time he was in Heishuitan, and his understanding of the Dantian Linghai was not much more thorough.

He also finally understood how valuable the spirit stone was to a cultivator.

"With these pure spirit stones, I can gather the spiritual power in the Spirit Sea faster."

Pang Jian knew through Ning Yao that the main stage of the Qi Refining Realm was to continuously refine spiritual power, and finally fill the spiritual sea with spiritual power.

Since he had pure spirit stones available in his hands, he had no intention of saving, so he immediately let go and cultivated.

……

Dark.

"Ning Yao", who was separated from him by some distance, habitually sat cross-legged among the leaves, looking at Pang Jian condescendingly.

With her cultivation attainments and the degree of refinement of her soul, she faintly saw that when Pang Jian was cultivating, the remnant soul spirit of many mosquitoes, flies, and insects had just been incorporated into the dantian spiritual sea by Pang Jian.

Suddenly, she looked stunned.

Hidden in the dark, like a Luo Meng-like "spiritual evil", when Pang Jian was cultivating with the "Hutian Qi Cultivation Technique", he was actually also attracted and wanted to escape into his dantian uncontrollably.

Taken aback, she hurriedly intervened with her will to evacuate the "spirits" from the edge of the Worm Valley.

"Such a domineering spiritual technique, this level of cultivation spiritual technique, should not be a product of the Fourth Realm."

She became more and more curious about the boy's past.

……

Time is in a hurry.

When the sky was about to dawn, Pang Jian, who had unknowingly digested two pure spirit stones, Huo Ran was awakened.

He instinctively clenched the dragon spear and looked coldly at He Rong who was approaching.

Seeing Pang Jian wake up suddenly, He Rong immediately stopped and said lightly: "I want to know the details of He Ziren's killing." ”

"If you have doubts, you can ask Ning Yao, or you can wait until dawn to ask me, why are you so sneaky?"

Pang Jian said unhappily.

"Because Ziren and her had a marriage contract, she was a little dissatisfied with our He family, and her attitude has always been cold, and she will not be willing to cooperate with me." He Rong explained helplessly.

Pang Jian recalled Ning Yao's words, thought for a while, and said, "Among the dark ghosts who attacked us, there was one person wearing a golden mask, and his identity seemed to be a little special. ”

Later, he died at the bottom of the Black Water Pool, and his mask was shattered. I saw that his entire face was covered with criss-crossing scars, and it was the son he killed your family. ”

Pang Jian was most impressed by the face under the broken mask, and he used that person as a shield.

He Rong changed color slightly after hearing this, he nodded, said thank you and turned back.

In the leaves in the distance, "Ning Yao", who had been looking at He Rong, changed from a sitting position to a standing position, and only when he returned to Su Yuntian's side did he restrain the blade-like cold light in his eyes.

In the darkness high above Pang Jian's head, Hong Tai, who had been refined into a "spirit evil", floated like a ghost.

Hong Tai, who is at the level of the Pulp Cleansing Realm, after being refined into a "Spirit Evil" by her, as long as she deliberately hides in the dark night, she will not be noticed by everyone present.

- Including He Rong and Su Yuntian.

"Ning Yao", who was staring at He Rong, saw that he just asked about the cause of He Ziren's death, so his face changed drastically, and he did not secretly instruct the "Lingsha" to attack.

"It's Dong Qianfeng! Dong Qianfeng of the Dong family actually defected to the dark ghost! ”

He Rong returned to Su Yuntian's side, his eyes showed horror, and he shouted in a low voice: "It was also Dong Qianfeng who killed Ziren!" ”

"He was tortured by the Burning Sun Sect at the beginning, and he was slashed on the face more than a dozen times, leaving indelible scars, and then he was expelled from the Burning Sun Sect."

"It's him who wears a mask and colludes with the dark ghost Hong Tai to hunt down the people of our Seven Great Families in the Cen Lin Mountains!"

Su Yuntian couldn't sit still, and exclaimed, "It's actually him!" ”

"Good thing he's dead." He Rong said again.

"Although Dong Qianfeng is dead, he ......" Su Yuntian touched his chin, his expression gradually became heavy, and said: "If Dong Qianfeng becomes a person of the dark ghost, then will his righteous son Dong Tianxue also become a member of the dark ghost?" ”

He Rong was shocked: "Impossible, right? ”

"Dad, what are you two talking about in the middle of the night?"

Su Meng woke up in a daze, and when she saw the ugly whispers on the faces of the two, she couldn't help asking.

"Nothing."

Su Yuntian wanted to smile and comfort him, but found that he couldn't laugh, so he said, "It's almost dawn, you're getting better, and we're going to get ready to go again." ”

"Oh."

Su Meng rubbed her eyes and replied.

Among the leaves, "Ning Yao" looked at the two of them from a distance, and the corners of her lips pursed lightly were cold.

From Hong Tai, she dug out a lot of secrets of dark ghosts, and naturally knew who Su Yuntian and He Rong were talking about.

She also knew that the man was indeed in the Cen Lonely Mountains.
