Yu Han built a formation around him, and at the same time covered his body with a large stone, and prepared many small vigilance arrays, so he sat down with confidence.

He took out the spirit bone of the Nine Shadows Forest Luo Flower from his bosom and placed it flat in front of him.

Feeling the cold breath that is constantly passed on, this dark grass looks more and more extraordinary.

"My strength has already reached the peak of the Bone Melting Realm, in fact, I should have melted my bones a long time ago!" Yu Han's eyes flickered.

Indeed, with his strength, he had already reached the apex of the Bone Melting Realm.

Especially during the days when he was specially trained by Li Qiankun, his foundation was even more thick and solid.

The reason why he did not perform bone melting was because he himself had been hesitant all along.

The Holy Beast-level spirit bones in the Disillusioned Bone Land are very limited.

And Ding Jin and Xu Fei have each obtained one, and it must be very difficult for him to continue to search.

Not only that, the Holy Beast Spirit Bones of the Disillusionment Bone Land have all been sacrificed by the powerhouses of the Seven States Martial Academy in the past dynasties, and judging from the power contained in the real spirit bones, a lot has been consumed.

Therefore, in comparison, the spirit bones derived from the Disillusioned Bone Land were really inferior to the Nine Shadows Forest Luo Flower in his hand at this moment.

Moreover, this spirit bone was snatched by himself with his life.

Although it is fortunate to a large extent, when it comes to the fundamentals, it can be regarded as a tiger's mouth.

This sense of accomplishment is extremely subtle.

Thinking of this, Yu Han's eyes flashed with a hint of determination, once the bone melting was successful, his cultivation and strength would also be greatly improved.

At that time, a level like Qu Hong could be easily killed even if he didn't need the Yin Yang Annihilation Array.

Not only that, but he is absolutely sure that after the success of the bone melting, he will defeat or even kill a master of the level of the crown.

Thinking of this, the corners of his mouth gradually hooked up a faint smile.

The battle with the crown was just after this trial.

This guy is already at the peak of the Bone Transformation Realm, and after being sad about this trial, it is very likely that he will break through.

If he doesn't melt his bones, I'm afraid he may not be his opponent.

Having made up his mind, Yu Han retracted his mind, there was a powerful power in the holy bone, so he had to maintain a clear Dao heart.

His eyes fell on the spirit bone in front of him, and a faint smile gradually appeared on the corner of his mouth: "I hope my choice is not wrong, you can perfectly integrate with my martial spirit!"

When the words fell, the palm of his hand poked out slightly, and a light wheel appeared in front of him, spinning rapidly.

Soul Vortex!

When he was still in the Qingwei realm, the Enlightenment Vortex was automatically derived from his body, and as soon as he appeared, he reached the realm of doing whatever he wanted.

This is really a bit scary.

At this moment, after so much time, this Enlightenment Vortex, which had been empty for a long time, finally came in handy.

As the vortex swirled down, his other hand gently provoked, and a ray of light shot out directly, submerging into the spirit bone.

Airplanes!

The Enlightenment Vortex shrouded in an instant.

At the same time, with the injection of his true qi, the light of that spirit bone flickered, and the power of the Nine Shades of Yin and Cold roared out!

"Melt bones, right now!"

Yu Han's eyes flashed, and the Spirit Vortex was like a giant mouth, absorbing that spirit bone into it in one fell swoop!

Call!

The root of bone melting lies in the fusion of the spirit bone and the bone in one's body, so that the power of the spirit bone spreads all over the body.

When the time comes, every gesture will be like a peerless holy beast descending, and it can even borrow the phantom of the holy beast to derive a set of great magical powers out of thin air.

Therefore, after this spirit bone was incorporated into the Spirit Vortex, the power of the Nine Shadows quickly diffused out, and it began to compete with the power of the Spirit Vortex, and he was unwilling to be devoured like this.

"Since you're here, give me an honest fusion, how can you be allowed to go wild?" Yu Han gritted his teeth and snorted coldly.

The true qi in the body also surged out, and one after another swords swarmed out, assisting the Spirit Vortex and continuously refining this spirit bone.

Under the combined suppression of the two forces, the Nine Shadows Forest Luo Flower Spirit Bone was finally gradually defeated, and the light of resistance gradually dimmed.

This is a process of submission, and under normal circumstances, only the spirit bones produced by demon beasts above the spirit beast level have the consciousness and ability to resist.

Therefore, it must be subdued by its own strength.

Only in this way can it be truly perfected, and then the bones can be melted successfully.

Now that he waved his big hand, a ray of light directly roared out, and with the help of sharp sword intent, he finally subdued this holy beast spirit bone.

Looking at the Nine Shadows Luo Flower Spirit Bone who was lying quietly in the Spirit Vortex and no longer moving, a smile gradually appeared on the corner of Yu Han's mouth.

After submission, it is the process of melting, which is the benefit of the Enlightenment Vortex.

If you don't cultivate the Spirit Vortex, you can only rely on your own strength to forcibly fuse with the spirit bones.

When the time comes, not only the fit, but even the degree of melting will be much weaker, and a lot of the power of the spirit bone will be wasted.

Now Yu Han's Enlightenment Spirit Vortex can do whatever he wants, and he can even transfer the state of that spirit bone in it to Yu He's sea of consciousness without any difference.

In addition, he manipulated it with his heart, urging the Spirit Vortex to melt in a special delicate way.

So the certainty of success is very great.

Since you want to melt the bones, you must achieve perfect bone melting.

This is a bottom line of Yu Han's cultivation so far, and he will never allow a trace of flaws to appear!

Under the rapid rotation of the Spirit Vortex, the spirit bones of the Nine Shadows Forest Luo Hua began to become transparent, and they were no longer as black as ink as before.

Moreover, there was a sharp sword light flashing in it, and it was actually integrated into its own body, along with the little sword intent that remained in it before, making it contaminated with a trace of sword origin.

This is also the credit of the Enlightenment Vortex.

It was also at this moment that the power contained in the Spirit Vortex finally grew to a peak.

Yu Han's brows furrowed slightly, and all the impurities in the Nine Shadows Luo Flower Spirit Bone had faded.

Instead, there was a crystal clear spiritual grass, swaying countless spiritual qi between the swings of the wind.

Then the last step is to integrate into yourself.

If this step is successful, it means that he has successfully entered the realm of bone melting.

His face had become extremely solemn, for this was the last step, but it was also the most difficult.

I don't know how many disciples failed to melt their bones at this last step, so they had to choose to give up.

And you have to succeed at the first time.

Because he can't afford to lose!

Especially the spirit bone of this Nine Shades Forest Luo Flower, when he wanted to fuse it at the beginning, he felt that the Nine Shades aura contained in it did not coincide with his own Dao.

So at that time, he still felt some regret about this spirit bone.

However, until this moment, after the purification of the Spirit Vortex, the aura of this Nine Shadows Forest Luo Flower had obviously become much purer.

And with that trace of the sword path contaminated, this spirit bone appeared more and more mysterious.

In this way, all his previous worries and regrets naturally faded.

It was almost foreseeable that once he fused this Holy Beast Spirit Bone, his sword path would also make great progress.

So, be sure to succeed!

His eyes flickered, and he focused all his heart on this spirit bone, and then, the Spirit Vortex flew up in the air and landed directly on the top of his head.

Yu Han shook violently in an instant, and directly felt a huge force, spreading along the limbs and hundreds of bones, towards every inch of bones!

Those strong aura surged out in an instant, and began to make the most direct contact with his bones!

You can clearly feel the energy contained in that power.

It is no wonder that the mid-stage realm of bone melting after bone melting is far more than that of the same level realm powerhouse who has not melted bones.

This is almost the existence of a cheat, and in the case of reaching the extreme, it is once again raised to a terrifying level.

This is also the charm of bone melting.

And the level of integration into the spirit bone is also the foundation of the strength and weakness after the bone melting.

Call!

The terrifying aura raged in his body, and the crystal clear Nine Shadows Luo Flower Body lay quietly on his skull.

The breath released from it starts from the skull and spreads towards the neck, chest, and limbs!

Until every inch of bone is infiltrated by this force, and the body and skull are completely integrated, then the bone fusion is over.

Yu Han didn't dare to be careless, but he was secretly relieved in his heart.

Fortunately, everything is going well at the moment.

If the situation continues at this moment, it will be possible to melt the bones in less than an hour.

The spirit bone of the holy beast is really terrifying, no wonder a piece of the spirit bone of the holy beast will provoke countless strong people to fight bloodthirsty.

He was secretly glad in his heart that this bone was not easy to come by.

At this moment, the pure power of the Nine Shadows Forest Luo Flower Spirit Bone had already spread to the position of the chest.

And some of them are stretching towards their arms!

However, at this moment, Yu Han's originally calm face suddenly turned into a shock.

The power of the spirit bone spread to an abrupt halt.

Then, suddenly, the tide flew back!

"How is that possible?" Yu Han's face suddenly changed.

When the power of the spirit bone retreated, it also took away a trace of the origin that was originally carried in his own bone.

Therefore, once you fail, your strength will be greatly reduced.

It's a double-edged sword, and as you gain it, you also lose it.

"Actually, did you fail?"

The corners of his mouth gradually flushed with a hint of bitterness, the scene appeared too suddenly, and he didn't have time to imagine why it suddenly stopped when it had gone so smoothly before.

Moreover, the speed of evolution is extremely fast.

In just a short moment, all the power had retreated into the body of the Nine Shadows Luo Flower above his head.

The power in the body is also losing a lot.

The spirit bone spontaneously emerged from the top of his head and landed in the palm of his outstretched palm.

Seeing that the grass stems began to gradually turn into their previous dark appearance, a trace of indescribable loss appeared on Yu Han's face!

"Still not working? Perhaps, this is fate!"

He shook his head and sighed, his gaze surprisingly downcast.

At this moment, the Nine Shadows Forest Luo Flower, which had just regained its body color, suddenly trembled rapidly in his palm.

Then, the volley flew into the air and fled into the distance!
