"Buzz ......"

In the lonely and empty mine, there was a gust of wind, like a violent wind pouring in.

Under Mu Lao's terrifying speed, Du Zhong came to the deepest part of the mine in the blink of an eye.

"Master, put me in the middle."

Du Zhong gasped, and seemed to have some difficulty even speaking.

Hearing this, Mu Lao immediately put Du Zhong in the center of the mine according to Du Zhong's meaning, and asked him to sit cross-legged.

"Master, I'm going to trouble you to protect me this time."

His face was pale, and he endured the severe pain in his body, Du Zhong opened his mouth and said.

Mu Lao nodded immediately, and said softly in a nervous tone: "There must be no trouble, do you hear?" ”

"Master, don't worry, I still have a big revenge."

Du Zhong held back a smile.

As soon as the corners of his mouth hooked, he thought of Gu Mu'er, and his heart suddenly ached.

"Bang ......"

At that moment, there was a rush of running.

Mu Lao raised his eyebrows.

He glanced at Du Zhong, only to find that Du Zhong had closed his eyes tightly and began to recover.

"Huh."

Seeing this, Mu Lao's figure moved and rushed out.

Before he could break out of the mine, he saw Du Zhong's group of comrades, who were hurrying towards the depths of the mine.

"Stop!"

Mu Lao opened his mouth and shouted, then looked at everyone and said: "Du Zhong is treating inside, don't go in and disturb him, this matter is life and death, you should guard the door well, don't let anyone in!" ”

Hearing this, the crocodile and the others immediately responded.

Everyone rushed to the entrance of the cave as if they were facing a great enemy.

At the same time, Mu Lao rushed out of the cave to protect the Eucommia.

With him, no one wants to go in and disturb Du Zhong!

At this moment, sitting on the energy stone vein, Du Zhong clenched his teeth, and under the stimulation of the severe pain, he forcibly condensed his mind and began to absorb energy from the ore vein.

"Hoo ......"

Even with his eyes closed, Du Zhong's rapid breathing still didn't stop.

While absorbing the energy, Eucommia quickly fell into the consciousness space, and under the sweep of spiritual power, he began to observe every detail in his body.

When he saw the broken dantian, Du Zhong couldn't help but smile bitterly.

"Huh?"

With a wry smile, Du Zhong froze.

For dantian, Du Zhong has already given up.

As a martial artist, he knew very well that it was impossible to repair the broken dantian.

Now his only thought is to save his life, even if his martial arts are abolished, he will definitely be able to start over again and avenge Gu Mu'er and Mu Lao!

However, just when Du Zhong was holding this idea, he found that a small transparent sword body appeared in the broken dantian.

"Emperor's Sword!"

If you look closely, that little sword is the first sword.

This result surprised Eucommia.

"What's going on?"

Du Zhong still clearly remembered that the emperor's sword was not a good thing.

At the same time, Du Zhong controlled his mental power and stepped forward to investigate.

"Actually contains energy?"

During the investigation, Du Zhong condensed slightly, and then his heart was shocked.

"There is such abundant and incomparably strong energy in this little sword?"

"How is that possible?"

After a closer look, Du Zhong suddenly found that the energy contained in the little sword turned out to be the energy of the dragon yang fruit that he had not digested.

While absorbing the energy and nourishing the injuries in his body, Du Zhong pondered.

"At that time, wasn't the energy of the Dragon Yang Fruit swallowed up by the black flames that erupted?"

"Most of the injuries in the body are caused by the black flame."

"Is it ......?"

Eucommia suddenly flashed in his mind.

"Black Flame only has the last trace of it, it stands to reason that even if I instantly devour the energy of my whole body under the detonation of my full strength, it is impossible to completely devour the energy of the Dragon Yang Fruit."

"Could it be that that black fire is the core of the whole black fire."

"The reason why it has been hidden in the energy of the Dragon Yang Fruit and has not been refined is because the energy of the Dragon Yang Fruit cannot refine it?"

"Yes, it must be so!"

Du Zhong nodded secretly.

"Because of the reason that it can't be practiced, the energy of the Longyang Fruit is allowed to let the black fire grow and turbulent wantonly, and after the black fire disperses the core energy in the outbreak, the energy of the Longyang Fruit will be broken one by one and practiced!"

"No wonder the remaining Dragon Yang Fruit energy in the little sword is so full and upright!"

Thinking of this, Du Zhong couldn't help but secretly rejoice.

At that time, if the energy of the Dragon Yang Fruit had gone all out to stop the black fire from breaking out, he would probably have died in the hands of the Holy Maiden of the Zhou family.

If the energy of the Dragon Yang Fruit could not completely refine the black fire in the end, he would also be burned by the black fire that broke out from the inside out, and the result would be death.

The occurrence of this kind of abnormality should really be fortunate for Eucommia.

"And what about this little sword?"

Knowing the formation of the energy in the small sword, Du Zhong immediately focused his attention on the miniature version of the Emperor's First Sword.

Think about it.

Du Zhong immediately remembered.

At that time, when he was about to kill the holy daughter of the Zhou family, three old men came to the rescue.

When colliding with the three old men, Du Zhong felt a strong but somewhat soft energy, as if it was not acting on the body, but directly acting on the body, and pushed him out.

It was also that blow that the emperor's sword shattered.

Ancient Excalibur.

How could it be so easy to break?

There is only one answer.

It's just that Kenshin is gone.

The Excalibur that has lost Kenshin is no different from an ordinary weapon, except that it is a little sharper and harder than an ordinary weapon.

"If this is the sword heart of the Emperor's First Sword."

"This little sword, could it be that it is circulated in the martial arts, Jian Dan?"

As soon as he thought of this, Du Zhong couldn't help but get excited.

Jian Dan.

In ancient times, only martial artists who practiced the way of the sword could cultivate the sword pill.

Although the sword pill is the same realm as the Jin Dan in the martial arts method, the martial artist who cultivates the sword pill will be more powerful and sharper than the martial artist in the same realm in terms of attack power and speed.

"Whew!"

As soon as my heart was excited, the pain suddenly intensified.

"Whether it's a sword pill or not, you have to heal the injury first and then slowly observe!"

Because of being in the center of the energy mine, Eucommia quickly absorbed enough energy.

With enough energy, the treatment officially begins.

"The viscera already have a part of the energy being nourished, and the broken organs have begun to be repaired under the nourishment of energy."

"Now only the meridians remain."

Looking at the scattered meridians in his body, Du Zhong couldn't help but smile bitterly.

Under the scorching black fire, every meridian of Eucommia ulmoides was full of burn marks, and many of them were shattered and broken by the black fire.

"The meridians must be reconnected first, and then the energy can be used to reconnect!"

Do what you think.

Du Zhong immediately controlled the energy that had been absorbed into the Phantom Pill and repaired it from the first meridian.

Energy, like repairing slime.

Attached to the inner and outer layers of the meridians.

With every movement, Eucommia could feel a piercing pain.

In the meridians, there are still some black fire energy remaining.

These energies are like icy water, and the energies controlled by Eucommia are like piping hot oil.

As soon as the two come into contact, an explosion will inevitably occur.

Fortunately, with the suppression of energy, Eucommia can still survive.

Soon.

Du Zhong controlled the energy and turned around all the meridians of the body, sweeping away the remaining black fire energy, and at the same time, attaching the energy to the inner and outer layers of all the meridians, constantly repairing.

A full hour of time.

It took all the energy to restore the meridians of the whole body.

Subsequently, Eucommia began to reorganize and penetrate the meridians.

It should be the reason for the rebirth of the meridians, the meridians that have been all opened up before, are blocked again, and the energy cannot run in the meridians at all.

In this case, Eucommia had to open the meridians again.

Fortunately, because the Phantom Pill has been condensed, and it has also opened up the meridians once before.

This time, Eucommia seemed to be familiar with the road.

But even if I am familiar with the method of opening up the meridians, when I clean the meridians, the severe pain is still the same as last time, and it has not diminished in the slightest.

"Fortunately, while repairing the meridians, most of the internal injuries have been healed, otherwise I really wouldn't be able to bear this severe pain!"

While rejoicing in his heart, Eucommia began to impact the meridians.

This through, day and night, passed quickly.

After enduring a day and a night, severe pain.

The meridians of the whole body were once again opened up by Eucommia.

I don't know what the reason is, maybe it has something to do with the sword pill, or maybe it has something to do with the broken meridians, after opening the meridians this time, Du Zhong found that the meridians in his body were several times thicker than before.

And the intensity has also increased considerably.

The next day, at noon.

All of Eucommia's injuries have healed.

The meridians are connected.

The energy in the body has long been depleted.

"Buzz ......"

The mind moved.

Eucommia directly uses spiritual power to frantically absorb the energy in the heaven and earth, as well as the energy ore.

While absorbing energy, Eucommia compresses the energy that has just entered the body.

These energies did not enter the meridians, but were sent into the Phantom Pill by Eucommia.

The energy is absorbed very quickly.

The compressed energy is continuously injected into the elixir.

With the influx of energy, the Phantom Pill became more and more condensed.

The blue energy pill body, which originally seemed illusory, gradually condensed into a hard blue core, and with each injection of energy, the core would grow slightly.

"Boom!"

A little while, when the outermost layer of the Phantom Pill also condensed into a hard shell, Du Zhong's brain exploded.

Phantom pill, condensed.

No, it should be said that it is Shidan, and the condensation has been successful!

This result had long been expected by Du Zhong, and when the Phantom Pill condensed the core, Du Zhong knew that this time he would definitely be able to condense the Shi Dan.

Because of the reasons that had been expected for a long time, Du Zhong was not excited by this.

He knows it well.

The so-called three realms of Jindan require the upper, middle and lower dantian to all condense into a solid pill, and finally aggregate the three solid pills into one in order to become a real golden pill.

Now he is still early from the Jindan Realm.

The lower dantian is formed.

Du Zhong didn't stop there.

On the contrary, with the help of a huge energy flow, it continued to be continuously compressed and converved, and poured into the middle dantian.

Prior to this, Eucommia had never developed a mid-dantian.

Generally speaking, what a warrior needs to use is only the lower dantian, the middle dantian and the upper dantian are almost not used, unless it is a super master whose strength is strong enough to a certain extent, he will develop the middle dantian and the upper dantian without being able to improve his strength.

There is no record in the history books, and he himself has no idea what will happen to the Zhongdantian once it is developed...... R1058
