The fire of the Nirvana Fire was much larger than the previous one, and its tens of meters were covered by the raging flames.

But at this moment, Chen Huan no longer felt pain, and the burning pain inside and outside the body disappeared.

Scorch on the skin also sheds.

What surprised Chen Ye was that this near-death injury consumed very little vitality.

Even less than one percent in the past.

Chen Yun finally understood what Befra said, that the fire of Nirvana is the key.

I also understand the secret of the undead bird.

Nirvana fire can reduce the consumption of vitality by 99%, which is equivalent to increasing your vitality by a hundredfold.

So under normal circumstances, it is almost impossible to kill undead birds.

Unless the process is interrupted.

It was as if Chen Kun had interrupted Red Eagle's Nirvana regeneration.

Chen Yan glanced at the Nirvana fire surrounding him, and directly entered his body.

This time Chen Yan no longer felt pain, but was a little bit dissatisfied.

Chen Zhe stretched out a hand, and immediately ignited Nirvana's fire on his palm.

With the palm of your hand, the fire of Nirvana also dissipated.

But Chen Yi was again in trouble now.

Nirvana's fire is considered a young man, right?

But how to cultivate and grow?

How can I develop my heart?

Chen Ye again took out a large amount of undead blood.

Ignite in the same way and then inhale.

Chen Yan could feel the fire of Nirvana growing.

But this growth is just a quantitative growth.

There was no qualitative change that satisfied Chen Kun.

Chen Yun tried to inject Xianli into the fire of Nirvana.

See if there is a response this time.

Although there was no response before, Chen Yan felt that there was no vitality injection before.

So there is no chemical reaction.

The moment when Xianli injected Nirvana Fire.

The flame changed from red to bright white.

Sure enough, the fierce chemical reaction of Nirvana's fire, vitality and fairy power can occur.

Chen Yun thought for a moment, and planned to change the operation mode.

First let the vitality be mixed with the fairy power, and then plunge into the fire of Nirvana.

This is the inspiration inspired by Chen Ye based on some strong ... fire ... medicine preparation process.

Just then, Nirvana's fire changed from white to golden yellow.

Chen Yun began to try to inject different proportions of vitality and fairy power one by one.

Nirvana fires are sometimes weak and sometimes strong.

Finally, after trying it hundreds of times.

Chen Ye finally deployed the golden ratio.

With a change of heart in Chen Yi, he can transform from a physical state into an energy form. Can he transform into a flame form?

Chen Yan started a new round of attempts.

What disappointed Chen Ye, however, was that Chen Ye couldn't completely transform himself into a flame form.

At best, let your body cover the fire of Nirvana.

However, Nirvana Fire has been strengthened.

But the heart still did not understand.

Is it necessary to condense in the heart?

Shouldn't be so one-sided ... or try it?

Chen Yan condensed the fire of Nirvana in his heart.

Suddenly, Nirvana's fire replaced blood, and began to be transported by the heart to every corner of the body.

what is this? Is this heartbreak?

Chen Ye was a little surprised.

But if you think about it, the word heartbreak has been around since ancient times.

In the eyes of the ancients, the heart is the root of man.

So heartbreak should be literal.

It wasn't the fire of the soul or the soul that Chen Yong originally thought.

After being transported from the heart to every corner of the body, Nirvana fire flows back to the heart again.

Time and again and again, endless and endless.

It seems that a set of its own trajectory has been formed.

Moreover, each time Nirvana's fire circulates around the body, the power of Nirvana's fire is strengthened a little.

The body also changed unexpectedly with the spread of Nirvana's fire.

Vitality has not been reduced by the burning of Nirvana's fire, but after grinding it leaves a more pure vitality.

As for Chen Xun's fairy power, under the tempering of Nirvana Fire, Chen Xuan felt indescribable.

Even this hot feeling has spread to Chen Yi's small world.

As long as you stand around Chen Yan, you will feel warm.

Nirvana's fire, vitality and immortal force, Chen Xiao's little world formed a circle full of vitality.

Of course, this circle will not make people die directly, but it will make people feel instinctively comfortable.

Chen Yan himself did not expect that this fire would be realized so easily.

There is almost no difficulty, everything is so natural.

Temper your blood with Nirvana's fire!

Now that everything was ready, Chen Yun planned to start his original purpose.

Chen Kun controlled the essence and blood in his body to merge into Nedan, and then Nirvana's fire began to train with Nedan.

Yin Yang Nei Dan has been turning.

After being tempered by Nirvana's fire, it turns faster.

The yin and yang neidan gradually turned into a vortex, a black hole greedily absorbing the heaven and earth aura of Xiaotiandi.

Human blood, blood of anger, and blood of gluttons are inherently distinct.

But at this moment also began to confuse each other in this vortex.

At first it was not clear who was who.

Nirvana's fire was also inhaled by the vortex and merged with the three blood vessels.

Chen Yan closed his eyes, and he didn't even realize that he was floating in the air with his arms open at this moment.

The surrounding world is like a huge network. The golden flames flow in this network, and centered on Chen Ye's body, flowing in and out constantly.

Eventually, the three bloodlines disappeared along with the burning flame, and finally red blood was restored.

I don't know how long it has been, Chen Yan opened his eyes.

Chen Yan looked at his hands, and the dark magma spread out.

Just then, a huge skull emerged from the dark magma.

It was a gluttonous beast. The shape of the gluttonous beast did not change much, but it changed from the original dark gray to black.

When Chen Yun's heart moved, the glutton's monster suddenly collapsed and turned into countless small gluttons.

Chen Min reached out again in the air, and the small gluttons collapsed again and turned into pure dark magma.

Chen Yan retracted the dark magma without any changes in his body, but Chen Yan immediately felt that his body had entered a state of dark assimilation.

Originally, after dark assimilation, Chen Yan's skin would become black and red, but there was no change at this moment.

In other words, the state of dark assimilation is gone, because it has changed from a temporary state to a normal state.

Because the blood of anger has truly become part of Chen Yi, the blood of gluttons is the same.

The first stage of retreat was considered a complete completion, and the effect was better than Chen Yi expected.

Chen Ye felt that it was necessary to enter the second stage of cultivation.

Organize and integrate most of your existing skills.
