"This thing, it should be the breath of that dirty thing, I didn't expect that just a trace of it could control a demon beast of the Transcendent Realm Great Perfection level."

The more Jiang Jiu thought about it, the more frightened he became, the dirty thing that was suppressed in the secret realm of yin and yang was inevitably too terrifying.

A wisp of breath is so powerful, if its deity appears, how terrifying must it be?

"Extinguish!" Jiang Jiu tried to manipulate the murderous aura to destroy the wisp of weird aura that was wrapped, but unfortunately the murderous aura was very powerful, but it was like encountering nothingness, and it couldn't cause any damage to this wisp of aura at all.

"I can't even touch it, it seems that my attack power level is too low!" Jiang Jiu said to himself: "The old dean said that only the power of the saint level can destroy the aura emitted by the dirty things, even if it is an old man, he can't help it. ”

Roar, roar, roar!

When Jiang Jiu's heart was complicated, more beast roars resounded all around.

Jiang Jiu knew that more demon beasts that had already been polluted had been killed.

Swish!

His powerful divine thoughts swept around, and found that there were more than a dozen demon beasts rushing through, and listening to the sound, there were countless demon beasts killed in the distance.

"It seems that a fierce battle is inevitable." Jiang Jiu took a deep breath, and there was solemnity in his eyes.

Just now, he found that although there was a beast soul in the body of the killed Lingyan leopard, it could not be absorbed by the Eternal Star Jue.

The beast soul seemed to have been polluted by the breath of dirty things, and had completely lost its divine essence.

Even their blood qi had been polluted and could not be absorbed by the Shura battle body.

In other words, within this secret realm, he was no longer able to absorb the beast soul and the battle soul to restore his strength, nor could he absorb the power of blood and qi to make the Shura battle body stronger.

All he can rely on is his own accumulation and heritage.

"It's no wonder that no one in the Yin and Yang Secret Realm, except for the old dean, can live, just dealing with these polluted creatures can be consumed alive." Jiang Jiu sighed in his heart.

"Fortunately, the aura between heaven and earth is very rich, several times richer than the outside world, and the deeper you go to the secret realm, the more amazing the aura of heaven and earth becomes. The most important thing is that I have a hundredfold Dao Sea, and I am not afraid of spiritual power consumption. ”

Jiang Jiu's body was running for thousands of years, and his body suddenly turned into a vortex, and the surrounding heaven and earth spiritual energy surged towards his body quickly, and in just a moment, he felt that the spiritual power in his body was much more abundant.

"If I practice here, my cultivation speed will be extremely fast, and in less than a year, I will have the hope of reaching a higher level.

If you enter the secret realm and cultivate deeper, the time required to break through will be much faster. Jiang Jiu muttered to himself, feeling the richness of the aura of heaven and earth in the secret realm of yin and yang, and couldn't help but be excited in his heart.

With the improvement of the cultivation realm, Jiang Jiu needed more and more energy every time he broke through the realm.

Every time he broke through the realm, the energy he needed was almost more than three times that of the previous realm.

With such a vast energy demand, it became more and more difficult for him to break through the realm.

Ordinary Dao Sea Realm cultivators only need 10,000 top-grade soul stones, that is, 100 spirit stones, to break through from the first heaven of the Dao Sea Realm to the second heaven of the Dao Sea Realm.

And Jiang Jiu's breakthrough to the Dao Sea Realm Double Heaven required a hundred energy stones from ordinary cultivators of the same level, that is, ten thousand spirit stones.

His current cultivation has reached the Dao Sea Realm Triple Heaven, and if he breaks through to the Dao Sea Realm Quadruple Heaven with spirit stones, he will need nearly 300,000 spirit stones.

300,000 spirit stones is not a small amount for a large sect, and for Jiang Jiu and some small sects, it is simply an astronomical number.

Fortunately, he can devour the battle soul and the beast soul to improve his strength, otherwise it would be difficult to ascend to the sky if he wants to go further.

But for now, he needs to kill all the polluted demon beasts that have come up first.

With the existence of these demon beasts, he naturally couldn't cultivate with peace of mind.

Roar Roar Roar ......

At this time, more than a dozen infected mutant demon beasts were killed, Jiang Jiu showed no mercy, and as soon as the crimson murderous aura realm came out, enveloping them all.

The murderous aura was surging, turning into substance, and instantly crushing the bodies of more than a dozen mutant demon beasts into pieces.

Wisps of black gas flew out, and finally melted into the void and disappeared.

Jiang Jiu didn't care about those weird black qi either, but his eyes showed a look of determination, and he rushed deeper into the secret realm.

"I want to see how strong the infected demon beasts are in the deeper part of the secret realm?"

After seeing the contaminated demon beasts here, Jiang Jiu was also secretly on guard.

But the weird black qi couldn't be guarded against, and he couldn't even detect the existence of those weird black qi.

He didn't know if these strange and ominous black qi would sneak into his body like the demonic qi that almost made him fall into the demon, and he couldn't find it.

All he could do was to be on guard, and there was nothing else he could do.

Puff puff!

One by one, the polluted demon beasts were strangled by the Murderous Qi Realm, and black blood splattered everywhere, with a pungent smell of blood.

In the killing, Jiang Jiu's murderous qi realm was also slowly getting stronger, and along with the murderous qi realm, there was also his Shura battle body.

"I didn't expect that killing these polluted demon beasts can also make my Shura battle body stronger, it seems that my Shura battle body will be the key to whether I can survive in the Yin and Yang Secret Realm."

Feeling the Shura battle body and murderous aura realm that had become a little stronger, Jiang Jiu finally had some confidence in his heart.

Roar, roar, roar...

As they go deeper into the secret realm, the demon beasts in the secret realm are getting stronger and stronger, all the demon beasts exude a strange and ominous aura all over their bodies, and they all have hideous black barbs on their bodies, and there is even more weird black qi that makes them almost immortal.

Jiang Jiu had to completely crush their bodies in a short period of time, otherwise he wouldn't be able to kill them at all.

"These ghosts are too difficult to kill, they are getting stronger and stronger, their vitality is getting stronger and stronger, and it is more and more difficult to kill."

Jiang Jiu's body was shrouded in a surging crimson murderous aura, like blazing blood emitting a demonic blood light, burning fiercely.

At this moment, within a radius of ten zhang of his body, the crimson murderous aura turned into a domain, and the murderous aura was vertical and horizontal, and everywhere he went, everything turned into blood, and all the polluted demon beasts were instantly crushed to pieces.

Card rub!

Suddenly, there was a strange sound from Jiang Jiu's body, and then an amazing sharp pain instantly erupted from his back, and the sharp pain spread throughout his body in an instant, making him miserable.

"Ahh

Jiang Jiu couldn't help but let out a miserable scream, and his hand couldn't help but touch his spine, only to see that the spine was already bloody, and there was an incomparably hard bulge in the spine, as if something terrible was about to drill out of his spine.

"How... What's going on? How can my back change? ”

Jiang Jiu muttered to himself in pain, and a huge fear arose in his heart.

"Could it be...... Have I been unconsciously caught up in the smell of that filthy thing... Infected? Not ......"
