"Returning to the Great Taishang Elder, those two have entered the Earth Demon Cave!" Hearing the old man's inquiry, Zhang Tiecheng hurriedly spoke.

"Haha, I didn't expect someone to kill themselves!" the old man couldn't help but sneer when he heard Zhang Tiecheng's words.

"Huh?" Hearing the words of the Grand Elder, Zhang Tiecheng was obviously stunned, not understanding what it meant.

"You don't know, the reason why this Heavenly Demon Cave is called a forbidden place is because there are many dangers inside, that is, the strong people of the Spirit Martial Realm, even if the strong people of the higher realm enter, they are all dead and alive!"

Seeing Zhang Tiecheng's puzzled expression, a middle-aged man explained.

"This Heavenly Demon Cave is really so terrifying!" Hearing the middle-aged man's words, Zhang Tiecheng couldn't help but be taken aback.

Although he knew that this Earth Demon Cave was the forbidden place of the Earth Demon Sect, he didn't know that the Earth Demon Cave was so dangerous.

Even the powerhouses of the Spirit Martial Realm are dead and alive when they enter, how terrifying it is.

"It's really cheap, that dog thing, he died in the Earth Demon Cave, and I wanted to catch him and break him into pieces!" said a middle-aged man with some regret.

Obviously, in his opinion, Ye Hao's entry into the Earth Demon Cave must be dead or alive!

"Okay, let's all go back!" "The Supreme Elder took one last look at the Earth Demon Cave, and then said to everyone.

Because the Earth Demon Cave is extremely terrifying, even if he is an eighth-order powerhouse in the Spirit Martial Realm, he also doesn't know what is in the Earth Demon Cave.

Of course, they also sent countless people into the Earth Demon Cave, but basically they all died inside.

And the only one who came out of or out of the Earth Demon Cave was the ancestor of the Earth Demon Sect, and his strength cultivation was at the peak of the Spirit Martial Realm.

That ancestor came out with only a broken exercise, but before the ancestor could say what was in the Earth Demon Cave, he had already died of serious injuries.

Since then, the Earth Demon Sect has regarded the Earth Demon Cave as the forbidden place of the Earth Demon Sect.

After all, even the peak powerhouse of the Spirit Martial Realm is a mortal existence when he enters, who would dare to enter it.

Later, however, they studied the mutilated exercises brought out by the ancestor.

They found that after cultivating, they could actually produce black qi in their bodies.

This kind of black qi can make their cultivation speed stronger, and their strength is much stronger than that of people in the same realm.

Therefore, this incomplete exercise is regarded as a treasure by them.

In the same way, they know that although this exercise is incomplete, it is very rebellious.

To avoid being remembered by people with a heart, they only give this exercise to the core personnel of the Earth Demon Sect to cultivate, and the loyalty of these core personnel to the Earth Demon Sect is naturally needless to say.

The mystery of this mutilated technique is only known to the people in the Earth Demon Sect.

So to get back to the point, Ye Hao and Su Lie entered the Earth Demon Cave, and in their opinion, it must be impossible to come out again.

......

"Why is it so dark!" After Ye Hao and Su Lie entered the Earth Demon Cave, they felt very dark, and they could only see the distance of dozens of meters in front of them.

You must know that when he reaches this kind of cultivation, he can already ignore the night, although he can't look at it with his spiritual sense like the Spirit Venerable realm.

But with the naked eye, you can see things for miles.

"My lord, there is a strange thing in this cave, and there is black gas everywhere, and this black gas is actually attacking me, wanting to invade my body. At this moment, Su Lie spoke.

"It seems that it should be because of the black qi of the earth!" Hearing Su Lie say this, Ye Hao spoke.

At this moment, Ye Hao also had a solemn look on his face, because he also felt that this black qi was attacking him.

He can only use his spiritual power to protect his body and block the respect of the earth's black qi.

But the black aura of the earth seems to be endless, constantly consuming its spiritual power.

And the further you go in, the more intense the black qi becomes, and the consumption of your spiritual power becomes faster and faster.

If his spiritual power is consumed and invaded by the earth's black qi, then he will be in danger.

"My lord, my aura is strong, you are close to your subordinates, and your subordinates will help you resist the invasion of this black gas. Su Lie said.

When Ye Hao heard Su Lie's words, he didn't refuse, and approached Su Lie directly.

It wasn't until Su Lie's spiritual power, guarded by his body, that Ye Hao withdrew his spiritual power.

However, Ye Hao was still very worried, because he didn't know what the specific antidote to the black qi of the earth was.

And the Earth Demon Cave in front of him seems to be extremely deep, and he doesn't know when it will come to an end.

He didn't know if the spiritual power in Su Lie's body could persist and find the antidote to the black qi by himself.

Just when Ye Hao was worried, a formation pattern suddenly appeared in Ye Hao's eyes, and then a black shadow shot out.

"It's the spirit of Tianyin!" Ye Hao was also a little surprised when he saw the appearance of the spirit of Tianyin.

You must know that this Heavenly Yin Spirit has been in his body and has not moved for a long time.

And because, because the spiritual cultivation of Tianyin was too low at this moment, he couldn't give him any help at all, so Ye Hao didn't summon the spirit of Tianyin!

"Master, these black qi can improve my strength!" Suddenly, a voice came from Ye Hao's mind.

Ye Hao knew that this voice came from his own Heavenly Yin Spirit, because the Heavenly Yin Spirit had already given birth to spiritual wisdom!

"I can improve your cultivation!" Ye Hao heard the words of the Heavenly Yin Spirit, and his heart suddenly rejoiced.

You know, he has never found a way to improve the cultivation of the Heavenly Yin Spirit.

And although the Heavenly Yin Spirit is in his body, his cultivation has been slowly improving.

But at this moment, the spiritual cultivation of Tianyin is only the tenth order of the Demon Venerable, and it is not even as good as his own cultivation.

What he didn't expect was that the Earth Demon Black Qi could actually improve the cultivation of the Heavenly Yin Spirit, which made him suddenly happy.

"Master, can I absorb this black qi?" the Heavenly Yin Spirit asked Ye Hao cautiously.

Ye Hao had already been able to hear from the tone of the Heavenly Yin Spirit that the Heavenly Yin Spirit was so dark about this place, he was really greedy.

"Absorb it quickly!" Hearing the inquiry of the Heavenly Yin Spirit, Ye Hao also hurriedly said.

After all, so far, he is still worried, how to resist the black qi after the spiritual power is consumed for a while.

And now that the Heavenly Yin Spirit can actually absorb it, so as to improve his cultivation, he naturally won't refuse.

"I don't know how much this little guy can absorb!" Ye Hao looked at the Spirit of Heavenly Yin, and couldn't help but look forward to letting the Spirit of Heavenly Yin absorb a little more of the Black Qi, so that he could reduce his pressure.

Ye Hao was even thinking about whether to leave the Spirit of Heavenly Yin in this Heavenly Demon Cave to specialize in cultivation.

But in the next second, it changed his mind, because a shocking scene appeared.

I saw that in the blink of an eye, the spirit of Tianyin seemed to have turned into a black hole, and it was frantically absorbed, and the surrounding earth shattered black gas!
