"What is this?"

Even Su Lie was startled at the moment, looking at the scene in front of him in shock.

After all, this place is so dark that even he is very afraid.

But the spirit of Tianyin is good, it is like a bottomless pit, frantically absorbing the black qi of the earth.

It's just that between breaths, the black qi within a few meters of the surrounding area has been completely absorbed.

Ye Hao also looked at the Heavenly Yin Spirit in amazement, because he saw that the cultivation of the Heavenly Yin Spirit had broken through from the tenth order of the Demon Venerable to the first order of the Demon Emperor.

The speed of this upgrade is like riding a rocket, that is, he has some envy for the spirit of Tianyin at this moment.

What is the difference between this method of upgrading and drinking water?

"It's so cool!" After absorbing the earth-shattering black qi around him, the Heavenly Yin Spirit continued to rush inside!

As long as the spirit of heaven and yin passes, the black qi of the earth is crazy and drills into his body.

"It seems that I underestimate him too much!" Ye Hao couldn't help but exclaim as he looked at the Heavenly Yin Spirit and the speed at which it devoured the earth's black qi.

It's a loss to himself, and he still wants to leave the spirit of Tianyin here to cultivate, but now it seems that he doesn't need it at all.

The Heavenly Yin Spirit was completely like a bottomless pit, frantically devouring the earth's black qi.

And the cultivation of the Heavenly Yin Spirit is also improving frantically.

Demon Emperor Second Order!

......

The third order of the Demon Emperor!

......

Demon Emperor Fourth Order!

......

The spirit of heavenly yin is constantly absorbed, and the cultivation is also constantly improving.

"What kind of perversion is this, state!" Su Lie looked at the Heavenly Yin Spirit in surprise.

Seeing that the Heavenly Yin Spirit continued to devour the Earth Evil Black Qi, and there was no need to refine the Earth Evil Black Qi at all, he could improve his cultivation, and he couldn't help but exclaim.

Ye Hao and Su Lie followed behind the Heavenly Yin Spirit all the way, constantly deepening.

But at this moment, they no longer need to release their spiritual power to resist the earth's black qi.

Because as long as you follow behind the spirit of Tianyin, as long as the spirit of Tianyin arrives, all the black qi of the earth will inevitably be absorbed by the spirit of Tianyin!

I don't know how long, there is not the slightest ground black gas behind Ye Hao, but the ground black gas in front of him is simply as rich as ink.

The Heavenly Yin Spirit was like a sponge, greedily absorbing the earth's black qi.

And at this moment, the cultivation of the Heavenly Yin Spirit is also very terrifying, and it has directly reached the tenth order of the Demon Emperor, which is still one step away from reaching the spirit realm.

You must know that the Heavenly Yin Spirit has reached the spirit realm, it is very terrifying.

Because the spirit of the Heavenly Yin can summon the Heavenly Yin War Beast!

And the cultivation of the Heavenly Yin War Beast is the same as that of the Heavenly Yin Spirit.

Therefore, if you raise the combat power of the Heavenly Yin Spirit, you will be equivalent to having a large number of strong men.

It was also at this time that the cultivation of the Heavenly Yin Spirit was raised again, reaching the first level of the spirit body.

Just this upgrade speed, let Ye Hao see it, and he couldn't help but pout his lips with envy.

Fortunately, this Heavenly Yin Spirit is his own subordinate, if this is his own enemy, it is simply terrifying!

As for Su Lie looking at the Heavenly Yin Spirit at the moment, he was completely stupid, and kept calling out the change, the state!

......

Time passed minute by minute, and Ye Hao roughly estimated that two or three days had passed, to say the least.

You must know that their speed is not slow, after all, the speed at which the Heavenly Yin Spirit absorbs the earth's black qi has never slowed down.

A cave can be walked for two or three days, and you can see how deep this earth-shattering demon cave is.

Ye Hao had no doubt that if he only relied on Su Lie and his spiritual power, even if he came here, it would probably not work.

Of course, along the way, he also saw a lot of pitch-black bones.

It can be imagined how terrifying the black gas of this place is, even human bones can be eroded and blackened.

Ye Hao also searched out some space rings from these people.

At the same time, it can be understood that these people are all people who entered the Earth Demon Cave to hunt for treasures in the past, but died in it.

Moreover, the cultivation of these people is not low, Ye Hao saw the notes of one of them, and that person's cultivation turned out to be the seventh order of the Spirit Martial Realm.

This terrifying cultivation is not much inferior to Su Lie.

Therefore, this Heavenly Demon Cave is really not something that ordinary people can enter.

If it weren't for the spirit of Tianyin, if you wanted to break into this earth-shattering heaven demon cave, it would be enough to choke without a spirit venerable level of cultivation.

What made Ye Hao feel strange was that in this Earth Demon Cave, there seemed to be nothing else except for the Earth Demon Cave.

But when he came here, Ye Hao naturally wanted to go to the end.

Moreover, in this Heavenly Demon Cave, you can also improve the cultivation of the Heavenly Yin Spirit, which is not without gain!

But he was still a little nervous in his heart, after all, if there was no antidote to the black qi here, then he really didn't know what to do!

Moreover, Ye Hao was also very curious, what was in this Earth Demon Cave, which was the energy source that continuously produced the Earth Demon Qi.

Looking at the Heavenly Yin Spirit in front of him, to be honest, Ye Hao was a little envious.

For two or three days, the Heavenly Yin Spirit continued to absorb the earth's evil black qi.

This made the cultivation of the Heavenly Yin Spirit directly reach the seventh order of the Spirit Martial Realm.

This is already far beyond him, and he is even already chasing Su Lie's cultivation.

As long as the Heavenly Yin Spirit is upgraded by three more levels, it can catch up with Su Lie.

Ye Hao looked at the black qi in front of him, and felt that the Heavenly Yin Spirit wanted to raise his cultivation to the peak of the Spirit Martial Realm, and he probably didn't ask much.

If this is spread and is known, it will inevitably be scared to death.

After all, two or three days ago, the cultivation of the Heavenly Yin Spirit was only the tenth order of the Demon Venerable, but now it has reached the seventh order of the Spirit Martial Realm.

This is almost across three major realms and twenty-seven small realms.

Just ask this Ancient Demon Domain, how many people can do it.

The key is that the cultivation of the Heavenly Yin Spirit at this moment is still growing.

Half a day passed again, and the cultivation of the Heavenly Yin Spirit broke through again, reaching the eighth order of the Spirit Martial Realm.

......

And at this moment, outside the Earth Demon Cave, some powerhouses of the Earth Demon Sect, including the Zhang family's father and son, appeared at the entrance of the Earth Demon Cave again.

At this moment, everyone looked at the Earth Demon Cave, and they all looked puzzled.

"It's strange, logically speaking, there should be more and more black qi overflowing from this Heavenly Demon Cave, why is it getting less and less. ”

"It's not because of those two people who entered the Earth Demon Cave. ”

"This is absolutely impossible, it is recorded in the sect that the ancestor of the eighth order of the Spirit Martial Realm has only been out of the Earth Demon Cave for just over a day, and he was seriously injured and died!

It had been four or five days since the two of them entered the Earth Demon Cave, and it was estimated that they had already died inside. ”

"That's true, but it's a bit strange that something happened to this Heavenly Demon Cave suddenly, do you want us to send someone to check it out. ”

Hearing this person's words, everyone fell silent instantly, because everyone knew that this Heavenly Demon Cave was full of dangers, and it was very likely that they would face death if they entered.
