Feeling Ling Shuang'er's terrifying formation fluctuations and Mu Hanqing's fierce sword light, the Heavenly Poison Jiao didn't dare to be careless, and two strange red rays actually shot out from his eyes the size of a grinding disc, cutting through the void and blasting towards the two women.

"Woohoo!"

Two strange red rays, one blasted towards Ling Shuang'er, and the other shot towards Mu Hanqing, each of which was able to seriously injure an ordinary five-star martial arts powerhouse.

"Boom!"

Ling Shuang'er, Mu Hanqing's attack, and the two strange red rays of the Heavenly Poison Jiao collided in mid-air, and a dull sound resounded in the cave, and the terrifying wind rippled like a storm.

At this moment, Mu Feng's fingers flicked out, and countless dazzling soul prints fell out like snowflakes, and then quickly melted into the air at an extremely fast speed.

A huge formation was condensed above the Heavenly Poison Jiao in an instant, and a series of red blood-colored thunder surged, as if hell had emerged, extremely hideous, faintly, and there were terrible screams coming out, which was terrifying.

This formation is naturally the Purgatory Blood Thunder Array, and Mu Feng used the Purple Spirit Thunder Source to absorb the power of the thunder in the black thunder before, which also happened to come in handy.

And the Heavenly Poison Jiao naturally felt the terrifying formation fluctuations of the Purgatory Blood Thunder Array, and this fluctuation made it feel a sense of danger in its heart, and it became agitated.

However, at this time, it was entangled by Mu Hanqing and Ling Shuang'er with all their might, and there was no time to deal with Mu Feng, which made Detian Poison Jiao also quite annoyed. Poisonous mist erupted from his mouth again and again, shrouding towards Mu Hanqing and Ling Shuang'er. In his eyes, there were strange red rays shooting out from time to time. It's also quite wolf to let the two girls deal with it.

Seeing that Mu Feng's formation was about to take shape, the Heavenly Poison Jiao became more and more agitated, and his blood basin opened his mouth, and he no longer spit out poisonous mist, but a black liquid.

"Frost, Hanqing, be careful!"

Mu Feng's face changed greatly when he saw those black liquids, these black liquids. It is the venom of the Heavenly Poison Jiao, and I don't know how many times stronger than the toxicity of those poisonous mist.

Mu Hanqing saw that it was already a little too late to dodge, so he flipped his palm, and actually sacrificed an umbrella-shaped spirit treasure, looking at the appearance, it should have reached the middle grade spirit treasure of the ground level.

The umbrella-shaped spirit treasure opened, enveloping the figures of Mu Hanqing and Ling Shuang'er.

"Zizizi!"

Those black venoms landed on top of the umbrella-shaped spirit treasure. Immediately, white smoke rose up, and the umbrella-shaped spirit treasure immediately corroded to the point that it could not be seen, but the black liquid of the Heavenly Poison Jiao was also blocked by this umbrella-shaped spirit treasure.

At this time. Mu Feng's Purgatory Blood Thunder Array was finally successfully arranged, and the formation was operational. Waves of terrifying formation fluctuations came out.

"Stand back!" Mu Feng stood in the air and shouted in a low voice.

Hear the words. As soon as Ling Shuang'er and Mu Hanqing's bodies moved, they retreated violently. And the huge body of the Heavenly Poison Jiao was shrouded in the Purgatory Blood Thunder Array.

The huge eyes of the Heavenly Poison Jiao also showed a hint of jealousy, and from this formation, it felt a strong aura of death.

However, the Heavenly Poison Jiao naturally would not sit still, and as soon as its huge body moved, the Jiaowei swept towards Mu Feng with a strong wind, and that kind of power was enough to explode an ordinary five-star martial arts powerhouse.

Seeing this, a touch of cold color flashed in Mu Feng's eyes, his handprints changed, and the purgatory blood thunder array ran rapidly, rolling one after another red blood thunder, and finally condensed into a violent blood-colored thunder that was a thousand feet in size.

From above this blood-colored thunder, the Heavenly Poison Jiao also sensed a familiar thunder fluctuation, the thunder power contained in the thunder wood.

A look of doubt flashed in the eyes of the Heavenly Poison Jiao, but he couldn't think about it, Mu Feng's handprint changed, and then his fingers suddenly pointed out, and the thousand-zhang blood-colored thunder roared out, and then slammed heavily on the tail of the Heavenly Poison Jiao.

"Boom!"

Thousands of blood-colored thunder, like a thunderous dragon, slammed into the tail of the Heavenly Poison Jiao, and the power of the violent thunder burst out, making the Heavenly Poison Jiao also let out a burst of mournful roar.

The huge body of the Heavenly Poison Jiao was also bombarded by blood-colored thunder, and it collided with the cave wall, causing the entire cave to be suddenly shaken, and a lot of rubble fell from the top of the cave.

Ling Shuang'er had seen the power of the Purgatory Blood Thunder Array before, but she didn't have anything, while Mu Hanqing was a little dumbfounded, she didn't expect that after Mu Feng cast the Purgatory Blood Thunder Array, the Heavenly Poison Jiao would be so vulnerable.

However, after all, the Heavenly Poison Jiao is a dragon demon beast, and its body is extremely strong, even if it is an ordinary six-star martial arts powerhouse in the early stage, if he is hit by a bloody thunderbolt, he will have to be hit hard, and the Heavenly Poison Jiao is only a little skinny, but he has not really suffered any injuries.

"What a strong body!"

Even Mu Feng sighed, with the help of the Purple Spirit Thunder Source, the power of the Purgatory Blood Thunder Array has far exceeded the scope of his own strength, as long as the power of the thunder devoured by the Purple Spirit Thunder Source is strong enough, it is not difficult to kill an ordinary six-star Martial Sect powerhouse, even if it is a seven-star or eight-star Martial Sect powerhouse, he dares to fight with it, of course, the premise is that he can smoothly arrange the Purgatory Blood Thunder Array.

However, I don't know if it's because the Heavenly Poison Jiao has not been in the Thunder Demon Mountain for a short time, and it may also have a certain resistance to the thunder power of Lei Mu, so the formation offensive that was enough to severely damage the early stage powerhouse of the ordinary six-star Martial Sect just now only made the Heavenly Poison Jiao suffer some flesh and skin, and it was not able to make it really hurt.

It's just that this kind of flesh and skin pain is enough to make the Heavenly Poison Jiao angry.

"Boy, you're going to pay a low price for this. Heavenly Poison Jiao opened his mouth and said.

"Really?" Mu Feng sneered, but his face was a little pale, although the power of the Purgatory Blood Thunder Array was extremely great, but with the cultivation of Mu Feng's four-star soul sect, it still had a lot of burden.

When the Heavenly Poison Jiao reached the seventh order, his spiritual intelligence was not low, so he naturally sensed Mu Feng's weakness and said, "I don't know how many times you can perform your offensive just now?"

"Hmph, won't you try it?"

Mu Feng no longer talked nonsense with the Heavenly Poison Jiao, his eyes condensed slightly, and when the handprint changed, the thunder power of the purple spirit thunder source devouring the thunder wood in his body was emanating without reservation, and it was integrated into the purgatory blood thunder array.

In the Purgatory Blood Thunder Array, the blood thunder rolled, and one after another amazing formation fluctuations came out, and the power was even greater, and a blood-colored thunder that was more powerful than just now was condensed.

When the blood-colored thunder was condensed, Mu Feng's eyes suddenly sank, and as soon as the seal was condensed, the blood-colored thunder shot out and blasted towards the Heavenly Poison Jiao. (To be continued......)
