Outside the Dragon Valley, the huge stone door of the Demon Emperor's Tomb emitted a dull noise.

Although the demon kings and demon generals felt strange, they couldn't figure out what the situation was, but they all looked vigilant, thinking that the heart of the demon emperor was about to come out.

Only the Black Wind Demon King knew that its clone used a secret method to self-detonate, completely triggering the Yin Qi that had accumulated in the Demon Emperor's tomb for tens of thousands of years.

"In order to prevent accidents, I deliberately asked the clone to carry a copy of the Ancient Yin Blood as a hole card. Once the snatching of the Demon Emperor's heart fails, it will ignite the evil energy inside. ”

At this time, the Black Wind Demon King was in a complicated mood.

This eternal yin blood is extremely rare, and the Black Wind Demon King is just out of preparedness, and he didn't expect it to really come in handy.

With the doppelganger blowing himself up, it meant that the possibility of winning the Demon Emperor's heart in the tomb of the Black Wind Demon King Demon Emperor was reduced to zero, which made him feel undoubtedly disappointed.

"The heart of the Demon Emperor is immortal, and it is the thing of the sun. But the Demon Emperor's Tomb is a place of calculation, and the evil spirit of the past 10,000 years has been suppressed by the Demon Emperor's heart. However, the eternal yin blood was spontaneously exploded by the clone and sprinkled into the entire space, and the yin and evil qi could no longer be suppressed! ”

Once the evil aura erupts, the Demon Emperor's tomb will have no life.

The heart of the Demon Emperor is unrefined, and sooner or later it will break through the Demon Emperor's tomb and fly to the outside world.

"At that time, the Demon Emperor's Heart will still fall into my hands!"

The Black Wind Demon King was secretly ruthless, since the clone failed to capture the Demon Emperor's heart, it would be better to take action in person.

In this way, the Black Wind Demon King's original frustrated mood calmed down a little.

It's just that he still can't understand what opponent his doppelganger encountered, and he actually used the most unlikely hole cards.

In the tomb of the Demon Emperor, the yin wind gusted fiercely.

The dark red sky became more and more gloomy, and Yan Xu's face hung in the air uncertainly.

In the dim space, the heart of the Demon Emperor was like a bright sun, emitting wisps of scorching light to illuminate a corner.

Lang Xie finally caught up with the heart of the Demon Emperor, and firmly embraced this beating heart with both hands.

The Demon Emperor's heart was a man tall, and Lang Xie's arms couldn't completely hold it, and the scorching temperature was like a fireball.

As if sensing the abnormal change in space, the temperature of the Demon Emperor's heart became higher and higher, and the light emitted was great, and a powerful vitality erupted to suppress the spread of the Yin and Evil Death.

The yin and evil qi is strong to a certain extent, and it can become the yin and evil dead qi.

Once an ordinary living creature comes into contact with the Yin Evil Death Qi, it instantly turns into a pool of blood.

The surviving demons in the Demon Emperor's Tomb have reined in their breath, not daring to urge mana and leak vitality at will.

Yin and evil dead qi are usually like a pool of stagnant water, but if they encounter living creatures or sense vitality, the more they will gather here to eat away at yang energy.

The heart of the Demon Emperor is the most yang thing, and the yin and evil death qi gushing out of the ground is constantly surging towards it.

Lang Xie is at the intersection of masculine anger and yin death, and the pain he endures can be imagined.

If he hadn't firmly grasped the heart of the Demon Emperor, I am afraid that he would have been turned into a pile of white bones by the strong Yin Evil Death Qi.

Demon Yu and Hebo looked at Lang Xie from afar, and they couldn't help at all, once they made a move, the golden crow might be engulfed by the Yin Evil Death Qi.

"No wonder the Black Wind Demon King clone said that sentence before he died, it turned out to be premeditated!"

Yan Xu frowned, the Black Wind Demon King's move was extremely vicious, and it was completely impossible to prevent.

The vitality of the Demon Emperor's heart is so powerful that sooner or later it will dispel all the yin and evil dead qi, and then it will see the light of day again.

But before this, everyone in the Demon Emperor's Tomb didn't know how many times they would die, and the Demon Emperor's heart was naturally unrefined.

If the heart of the Demon Emperor is out of the Demon Emperor's tomb, the demon kings waiting outside will definitely fight.

Since the Black Wind Demon King dared to detonate the Yin and Death Qi in the Demon Emperor's Tomb, there must be other back-ups, and the chance to compete for the Demon Emperor's heart was much greater.

"Black Wind Demon King, you have a good calculation!"

Yan Xu smiled bitterly and shook his head, looking around and thinking about what to do.

The yin and dead air was soft and cold and misty, and although Yan Xu felt uncomfortable, his reaction was not as great as that of other demon generals.

Yan Xu found that as long as the power of the law of life in the body was mobilized, a protective layer would be formed on the surface of the body, which would greatly isolate the invasion of yin and death qi.

Anti-audience demon generals, although they struggled to resist, no one comprehended the law of life like Yan Xu, and the effect was naturally greatly reduced.

"It seems that the law of life has a miraculous effect in resisting yin and evil death, and life and death are mutually reinforcing."

Yan Xu nodded with understanding, and walked a few steps in the yin wind, and the pressure he was under was still within the acceptable range.

He was safe and sound, and Yan Xu looked at Lang Xie who was hugging the heart of the Demon Emperor.

Contrary to the situation faced by the others, the pressure on Lang Xie mainly came from the heart of the Demon Emperor.

The heart of the Demon Emperor is a strange thing left by the Demon Emperor, not everyone can refine it, and it requires a certain amount of strength and luck.

Lang Xie's expression was hideous and painful, and it was obvious that the Demon Emperor's heart was putting great pressure on him.

The skin folds of the arms that surrounded the heart of the Demon Emperor were burned red by the hot heat.

The Yin Evil Death Qi completely intensified the vitality of the Demon Emperor's heart, which made it several times more difficult for the Lang Evil to refine it.

Once the will of Lang Evil is relaxed, it may be torn to pieces by the coercion emanating from the Demon Emperor's heart at any time.

Yan Xu didn't say a word, and immediately summoned the luck panel of the master's exchange system in Zhihai.

"Now there is only one way to help you, whether you can refine the heart of the Demon Emperor depends on your own creation!"

Yan Xu did not hesitate to mobilize all the sect luck that could be used, and infused them all into Lang Xie.

On the information on the character panel, Lang Evil Purple Qi Luck Avatar showed a little bit of golden starlight.

The golden luck represents the highest level of luck, and the luck of the Tianhao sect is gathered, which makes the luck of the Lang Evil purple show a touch of gold.

The pain that Lang Xie endured did not lessen, but Yan Xu obviously felt that his complexion was different from before.

After infusing Lang Evil with luck, Yan Xu did not sit back and watch the changes, and carefully searched for something everywhere.

"The heart of the Demon Emperor is a spiritual object, and I can't help Lang Xie refine it. But this evil life was accidentally detonated, and there may or may not be a way to suppress it. ”

Yan Xu flew high in the air and overlooked the entire space, trying to find the source of the yin and dead qi.

The secret space of the Demon Emperor's Tomb is isolated from the world, no matter how Yan Xu flies up, he can't touch the top of the space, and it will always be a dark red sky.

Looking down at the foot, a gray and gloomy dead air emerged from all directions, and at first glance there was no pattern at all.

Surrounded by a large area of yin and death, a red space in the center is where the heart of the Lang Evil and the Demon Emperor is located.

Yan Xu took strange steps, measuring the direction of the five elements in the space below, and his movements became faster and faster, and finally became an afterimage.

"Sure enough!"

Yan Xu stopped at dusk and whispered with joy on his face.

The seemingly chaotic yin and dead air still has its own rules, and there are hidden things under the layers of dead air.

Yan Xu summoned the Six Realms Heavenly Brush, constantly outlining a pattern of flickering formations, and quickly calculated the law of change of Yin and Death Qi.
