"The heart is condensed, and the flesh and bones are melted ......"

According to the method in "Xuanyang Nine Lives", let the aura run slowly in the body with a peculiar law, and with the operation of the aura, Ma Xie seems to be able to feel the existence of his internal organs, the beating of his heart, and the expansion of his lungs...... These inner organs gradually became clear in Ma Xie's heart.

This is the origin of "inner vision", when the aura can cover all the internal organs, the practitioner can fully see the situation in the body.

At this moment, Ma Xie focused all his attention on the "heart" part, which was the beginning of the fourth layer and the most critical step.

The heart is also the beginning of man.

This is the first organ formed by the human body in embryonic development, and it is also the source of human life, and it is also in charge of human blood.

Therefore, only when the divine treasure of the "heart" is opened can the practice continue.

The aura oozing out of the meridians gradually wrapped Ma Xie's heart, but Ma Xie did not rush to introduce the aura into the heart, but let the aura jump with the heart, until the beating frequency of the aura was exactly the same as the heart, and then the aura was introduced into the heart.

In an instant, Ma Xie's heart seemed to be pinched fiercely, and the fragile heart could not withstand the impact of the aura at all, and the operation of Ma Xie's meridians was also a little disordered.

This situation is the only way to practice, and Ma Xie did not panic, but forcibly "pressed" the aura into his heart with the severe pain in his chest.

Under the control of "Xuanyang Nine Lives", the aura is carrying out the most preliminary tempering of the heart, and when the tempering of this step is over, Ma Xie began a more difficult step.

"Golden Needle Refining Body"!

Fifteen golden needles carefully pierced the surface of the heart, and Ma Xie did not dare to penetrate too deeply, because the heart was so fragile that it could only be tempered little by little by boiling a frog in warm water.

With the transformation of the heart by the aura, Ma Xie suddenly felt that his body suddenly became hot, which was not mentioned in "Xuanyang Nine Lives", Ma Xie didn't know what the reason was, but he didn't feel uncomfortable, on the contrary, he could feel a strange power from his body.

At this moment, Ma Xie's eyes were closed, he didn't notice the special changes on his body, and the sweat oozing from his pores was all as red as blood!

Ma Xie was unaware of this, but felt as if his blood was being wound, burning his body.

"What's going on, going mad?" Ma Xie had a bad thought in his heart, he wanted to stop breaking through, break through without anyone to guide him, if he went mad, the consequences would be unimaginable.

However, the refining of the heart has reached the final stage, as long as the surface of the heart is all refined, it can be regarded as breaking through to the fourth layer of the Qi Refining Realm.

The burning sensation on his body became stronger and stronger, and Ma Xie felt that his flesh had been burned clean, and now the terrible flames burned his own bones!

"It seems that I only have one skeleton left, am I dead?" Ma Xie had a desperate thought in his heart: "Could it be that those ubiquitous black fires have eroded me?"

In this secret realm, there is that kind of mysterious black fire everywhere, and the biggest characteristic of this black fire is that it will interfere with the breakthrough of cultivators and lead them into the realm of going mad.

Thinking of this, Ma Xie had a retreat in his heart, he didn't want to repeat the mistakes of his master, so he began to restrain his mind and wanted to give up the breakthrough.

But at the moment when his aura withdrew from the heart outline, a voice came from his head: "Don't stop!"

The voice was old and dry, as if it came from the distant Nine Shadows, and it seemed to come from the heart of Ma Xie......

"Who?" Ma Xie was awakened, but he did involuntarily stop withdrawing the aura from his heart, and instead continued the process of breaking through, the voice seemed to him to be an order that could not be resisted.

With this, Ma Xie felt a violent wind rushing into his body, and after this violent wind wrapped Ma Xie, it turned into countless whirlwinds that penetrated into the pores of Ma Xie's body, and then kept stirring in his limbs and eight veins.

Ma Xie felt as if his body was about to be torn apart by the violent wind, and he was already in pain and unable to make any sound.

When he tried to use his aura to fight against this strange wind, he found that he was completely unable to control his body!

"I ...... Someone has been controlled!" Ma Xie found in despair.

"Fuck!" a sense of humiliation welled up in Ma Xie's heart, he really couldn't still be controlled by someone else's body.

But no matter how hard he tried, he couldn't move even a little finger, as if his soul was imprisoned in his body.

Through this, Ma Xie heard the voice in his head again: "The aura here is not enough, let's change places!"

Then, he felt his body fly, turn into a streamer, and leave the place at a very fast speed.

The huge fluctuation woke up Yuan Wuji and Jin Mushui, at this moment they had completely broken through and were still consolidating their cultivation, but they didn't even react to what happened for a while.

"What is that? It seems to have appeared from the direction where the horse evil is!" Yuan Wuji shouted to Jin Mushui.

The two rushed to the place where Ma Xie was, but found that it was empty, leaving only a pool of blood......

"What's wrong with Ma Xie? Did you get caught by something?" said Yuan Wuji worriedly.

"Maybe it's a monster in this secret realm!" Jin Mushui was also worried: "Let's go find him!"

With that, Jin Mushui also turned into a streamer and flew in the direction where Ma Xie flew away.

"Wait for me, big man!" Yuan Wuji also hurriedly followed behind Jin Mushui.

--------------------------------------

In the mountains at the end of the secret realm, black flames and red flames are entangled and biting each other, and this is already the depths of the secret realm, and these two strange flames can be seen everywhere.

In addition to these two flames, there was also an elusive green flame, and this green flame was the same flame that burned the shouting of Banyue Mountain Castle into a skeleton that day.

A group of cultivators walked cautiously here, and after they came down from the cave, they rushed to this mountain without stopping, because their purpose was only a strange treasure, the "Red Sky Divine Sword"!

This team of people and horses was none other than the Jade Venerable, and the three of them didn't think about Ma Xie and Jin Mushui at all, they just wanted to complete their tasks.

The mountains are full of prohibitions, unable to fly, facing the three major sects with strong soldiers and horses, the Jade Venerable is very careful to avoid its edge, although this person's character is corrupt, but he is indeed extremely cautious.

The three of them walked all the way into the depths of the mountain, but they never found the whereabouts of the strange treasure.

"Big brother, where is this strange treasure, we are almost done with this mountain. Is it buried in the ground again?" asked the Silver Venerable, panting.

"Shut up, if I knew I would still take you around in circles here?"

With just the three of them, how could they find the entrance before the three major sects. At this moment, he regretted a little that he had left Ma Xie and Jin Mushui behind, at least those two boys were good laborers.

"The king too, he obviously wants to get the divine sword, but he only sent the three of us, can't he drive out all the other forces and take possession of this secret treasure alone?" Venerable Jin also felt a moment of fatigue.

Seeing this, the Jade Venerable could only stop and rest for a while.

"Hey, you don't know, these three sects have been entrenched in the north of the Jin Kingdom for a long time, and their power is deep-rooted, and even the Xuanyang Sect does not dare to offend them easily. The king wants to prepare for a war against the Qin State, and the north may become the main battlefield, so the king still wants to win over the three sects. Besides, he said that he was looking for a secret treasure, but he wanted to test Shi Dangdang's strength, and now it seems that Shi Dangdang has produced that Mr. Mo, and there are really no decent cultivators around him. The Jade Venerable took a sip of water and continued, "These things are too complicated for the three of us to figure out. Don't underestimate that Shi Dangdang, as a mortal, his reputation is very high in the royal city, even the king of Jin is always jealous of him, otherwise why would he not change the stone city to a county?"

The two Venerables of Gold and Silver nodded as if they didn't understand, anyway, they only knew that what the eldest brother said must be right.

After a little recuperation, the three of them finally headed for their final goal, the highest peak of the mountain.

This is the commanding height of the entire mountain, and it is also the place where strange treasures are most likely to be hidden.

And at this moment, the disciples of the three major sects are also heading towards the mountain from three different directions, and the secret of the Great Mountain Hall is about to be revealed.

The four major forces marched from the ground of the mountain, their goal was very clear, it was the only treasure in this secret realm, and the two treasures on the wasteland behind them were not in their eyes, so they were left to those uninformed cultivators and bandits to fight for!

Behind these people, there were several figures following closely.

Behind the three Jade Venerables were Jin Mushui with Yuan Wuji, and behind the Tianwu Sect's team were the three of Patriarch Aoba, Feng Buping, and Boss Han.

The three of them had gained a lot in the wasteland, and the strength of the three of them was enough to crush the gangs of the Companion Moon Mountain City, and they were ambitious, and they had their sights set on this final place.

It was very quiet in the mountains, and each team moved forward quietly, but fortunately, this secret realm was very strange, there were no traps for any strange beasts, not even a single animal.

Jin Mushui and Yuan Wuji didn't know the situation on the mountain, they just chased the streamer, and the place where the streamer flew was on this mountain.

"What the hell was Ma Xie captured?" Yuan Wuji said: "Is it that kind of thousand-year-old monster?" I heard that some old monsters like to eat the meat of young men like you, crunchy and chicken-flavored. ”

Jin Mushui smiled and said to Yuan Wuji: "Then you have to be careful, I heard that some old monsters like to eat strange beasts like you the most, and didn't the old man surnamed Tao say, what kind of Nine Shadows Heavenly Beast are you? ”

Yuan Wuji broke out in a cold sweat every time he thought of this, he was really afraid that one day he would be captured by humans.

The two of them joked as they walked to the top of the mountain, and soon came to a halfway point up the mountain. From a distance, they saw three figures in front of them, Jin Mushui and Yuan Wuji did not follow, but waited for the three people to go away before continuing to move forward. In this secret realm, they are all masters of the fifth layer of the Qi Refining Realm, and the number of them is also outnumbered, no matter which team they meet, Jin Mushui and Yuan Wuji are not opponents, they can only avoid their edge.

Among all the people who went up the mountain, only the two of them did not go to the "Chixiao Divine Sword", they just wanted to find Ma Xie, and then look for some treasures that could improve their skills with Ma Xie in the top of the wasteland.

In this way, all the teams moved towards the goal in silence, and finally on the fifth day, the people of the Purple Immortal Sect took the lead in climbing to the top of the mountain, followed by the people of the Heavenly Martial Sect and the Xuanmen Destroying Sect, and the last to come up was the Jade Venerable and his party. And Feng Buping and Jin Mushui were still sneaking quietly behind.

At this moment, the people of the four major forces were speechless, not because they had no intention of talking to their opponents, but because they were all deeply attracted by the scene in front of them.
