As soon as Ye Chen walked into that small hole**, he sat down cross-legged directly, and emanated a trace of his thoughts. When he saw Wu Ming's appearance, he immediately smiled in his heart, and he was a very satisfied person.

Shout!

With a slight wave of his hand, a black ghostly aura rushed out, enveloping the cave in all directions. He is using ghost qi to isolate the movements that may be generated by his own cultivation, and he can't be careless here, and he can only survive by being cautious.

"Let's get started!"

Call!

As soon as Ye Chen's voice fell, he directly let go of the suppression of the ghost heart, and suddenly a majestic ghost qi swept from the ore vein. The ghost qi was surging, and it rushed into his ghost heart at once, and was compressed and refined into a ghost power.

Whew!

On the surface of the ghost heart, a raging flame was burning, scorching all the surging ghost qi, forming a magical and powerful ghost power. This kind of flame is very strange, pitch black, with a little bit of blue, and from time to time there is a flash of purple light, this is a ghost fire!

Hiss--

The ghost fire was boiling, and the raging burning was refining all the ghost qi one by one, making a hissing sound, which was terrifying. And Ye Chen sank into his soul consciousness sea and began to comprehend the method of promotion of ghost swordsmanship.

"Ghost Sword, Ghost Sword—"

"Condense ghost hearts, cast ghost bones, I see!"

Ye Chen murmured unconsciously, and through the comprehension of the ghost sword technique, he realized that the reason why he was able to easily kill that ghost warrior was because the ghost heart he had condensed was different from others.

He learned through understanding that one of his ghost hearts was a high-level ghost heart. There are many kinds of ghost hearts, many levels, and his ghost heart, which is condensed by ghost swordsmanship, is of a very high level. As for how high, he himself could not say, because there was no comparison, and there was no knowledge of the other ranks.

"So that's the case, no wonder I can skip the level and kill that ghost warrior!" Ye Chen muttered to himself unconsciously.

Sonorous!

At this moment, a subtle sound of gold and iron resonated from his body, from weak to strong, sonorous and endless. It's as if there are countless steels colliding, and it seems to be building something steel, which is amazing.

Bang!

At this moment, there was a faint blue light flickering in the center of Ye Chen's eyebrows, which seemed to be a blue flame. If you take a closer look, you will find that there is still a little purple in it, which is the heart ghost fire of the successful promotion. And the whole skull changed for a while, and a trace of blue-black lines began to appear, and there was a sonorous sound of gold and iron.

Hiss--

The blue ghost fire burned brightly, enveloping Ye Chen's entire head, forming a raging fireball. Wisps of black smoke rose up, and in the blink of an eye, they were scorched to ashes by the flames, making a sizzling sound.

Bang!

Sonorous!

The ghost fire was blazing, and suddenly exploded with a bang, and then there was another violent gathering, and with a sonorous sound, the entire head suddenly returned to its original state. However, after taking a closer look, he found that Ye Chen's face at this moment was realistic, as if he was a real person, not a ghost.

"The skull is finally complete!"

Ye Chen muttered this in his heart, and then, he continued to mobilize the raging ghost fire in the ghost's heart, and began to cast it from both hands. It was shocking to see a raging flame suddenly erupt from the ghost's heart, like a volcanic eruption!

Bear!

The ghost fire swept and burned, and in a blink of an eye, the two arms were enveloped. A burst of pitch-black smoke rose up, this was an impurity of Ye Chen's own body, the dregs of his soul, which was being scorched into ashes by the ghost fire.

Forging ghost bones can not only purify the soul, but also give birth to a powerful ghost power from the bone marrow, or the bone marrow is actually the power of ghosts. Once the ghost bone is successfully cast, its own strength is at least a hundred times stronger than before, which is the reason why Ye Chen cultivates this ghost sword technique, and other low-level exercises do not have such a strong effect.

Boom!

Knort! Knort!

At this moment, from Ye Chen's arms, there was an astonishing sound of gold and iron, sonorous and endless. A blazing ghost fire smelts a pair of arms as steel, and little by little casts a strong bone, which is called ghost bone.

Bang!

At a certain moment, the blazing ghost fire suddenly exploded, and it gathered away again, and in the blink of an eye, it was compressed into the two arms, forming a trace of blue-purple veins.

Boom!

Seeing that Ye Chen's arms shook slightly, a sonorous sound came out, which made the small cave tremble slightly. One of his arms was solid, no different from the real arm, except for a bloodless paleness.

"A pair of arms, it's done, it's the turn of a pair of legs next!" Ye Chen muttered unconsciously.

Call!

As soon as the words fell, the ghost heart suddenly erupted like a volcano, gushing out a terrifying ghost fire. The raging flames swept down towards the legs, and in the blink of an eye, they were completely submerged, and there was a hissing burning sound.

Sonorous!

The legs sitting cross-legged were trembling slightly, making a crisp sound of gold and iron, which was sonorous and endless. I saw that the blazing blue ghost fire was burning little by little, and it was forged little by little, forming a strange bone, which was called a ghost bone.

Qiang Qiang Qiang -

At this moment, a pair of legs were vibrating violently, and the sound of gold and iron came one after another, sonorous and endless, causing the Quartet to shake. Ye Chen, on the other hand, did not move at all, just continued to cultivate motionlessly, casting the ghost bones of a pair of legs little by little, and finally completed the casting of the bones of a pair of legs.

"It's finally done, and it's finally time to cast the bones of the upper body!"

Ye Chen was slightly happy in his heart, and muttered such a sentence, and after that, his heart was even more ferocious. The ghost fire was surging, erupting like a volcanic eruption, and in the blink of an eye, it swept through the entire body.

Rumble!

At this moment, a fierce ghost aura surged from the wall of the ore vein, which instantly merged into Ye Chen's ghost heart, and was instantly refined by the ghost fire in the ghost heart. Then, from all directions, there was a boundless ghost qi surging, and in the blink of an eye, Ye Chen was completely submerged in it.

Cracking sound!

Hiss!

Although Ye Chen was taken aback by the sudden change, he could not stop in his cultivation at all, he could only continue to condense his own ghost bones, ignoring these surging ghost qi at all.

Boom -

A majestic ghost aura penetrated from the center of his eyebrows, and then entered a pair of ghost eyes, and a wave of pain swept in, but it was endured by Ye Chen. He knew that this was a critical moment, and he must not just give up, otherwise everything for himself would be ruined.

Raging!

The ghost fire burned brightly, enveloping Ye Chen's entire person, forming a burning man. And what is surprising is that the ghost qi surging from all directions is even more ferocious, one after another, as if endless.

"What's going on?"

Rumble -

Wu Ming, who was mining outside and setting up a sentry, looked startled, feeling the ground shaking slightly, and seeing one terrifying ghost aura after another swept in, his face suddenly changed greatly.

Hey?

Soon, he was shocked, and found that the people in the distance were digging hard, and they were all unaware of the vibration here, which made him feel at ease at the same time, but also very strange.

"It's so rich, it's so pure!"

Wu Ming's face was taken aback for a while, and then, regardless of the three-seven-twenty-one, he leaned directly against the wall, gulping down the surging ghost qi, and was shrouded in a ghost qi in just one moment.

He was lucky, he could directly devour the ghost qi in such an environment, and finally be able to condense a ghost heart with this surging and endless pure ghost qi, and finally be promoted to a ghost pawn!

And Ye Chen in the cave was at the most critical moment, the whole person gritted his teeth and endured a boundless pain. This is a pair of ghost eyes, a ghost heart, and a ghost bone, a kind of boundless sharp pain.

"Hold on!

Ye Chen roared in his heart, his face turned hideous, and there was a blue-purple light flickering in his eyes, as if he was forging a pair of terrifying eyes. This is his ghost eye about to be promoted, he was originally born with a ghost eye, and he was promoted again for the first time he cultivated, and at this moment, it was the critical moment of promotion.

Shhh

Suddenly, two purple rays of light pierced through the eye, and with a hiss, two vacuums were torn out of the void in front of him. Finally, there was a slam on the wall, causing the surrounding walls to shake slightly, and the plaster slid down.

"What a strong ghost eye!"

Ye Chen's heart was extremely shocked at this moment, he had just suppressed the outbreak of the ghost eye, which didn't cause much movement, otherwise he really doubted that this cave would not be blown up by a single look.

Sonorous!

Bang!

At this moment, a crisp sound of gold and iron came from the body, sonorous and reverberatory, making the Quartet tremble. I saw that Ye Chen's body suddenly burst out with a strong light, which was a blue-purple light, which seemed to be a light coming from inside the body.

Boom!

Ye Chen's body shook slightly, and with a bang, the entire ground trembled slightly. An incomparably solid feeling swept from all over the body, the heart was stable, the soul was warm, and it seemed that there was a home.

"Is this a skeleton?"

Ye Chen's expression was infinitely surprised, and he finally cast a ghost bone, and his own strength was more than a hundred times longer. This powerful and solid feeling made him addicted for a while, and he didn't want to wake up for a long time.

"Pavilion Master, Pavilion Master, come out quickly!"

"Big things are not good!"

At this moment, Wu Ming's anxious voice came from outside, causing Ye Chen to wake up suddenly. Then, he frowned slightly, listening to Wu Ming's anxious tone, it seemed that something big had happened, which made him feel annoyed in his heart. Could it be that some force came to find something to do, which made him very angry, but now fortunately, he had just completed his cultivation, what if it was a critical moment?

"I'll see, who's looking for death again?"

Ye Chen's face was cold for a while, he muttered this, and walked out of this small cave in a blink of an eye.
