A fire bull demon beast on the sixth floor of the foundation. Such an opponent made Lei Dong's heart chill. If it weren't for the fact that the situation was really tense, he would definitely scold the ancient sect for having enough to eat, and the threshold was set on the second floor of the foundation building period. The demon beast guarding a black tower actually got a real demon beast to act as it. Even if Lei Dong wanted to break his head, he didn't know that this was actually the operating mechanism of this Heart Demon Palace. Not every tower is guarded by real monsters. Only occasionally the prohibition will detect that there are demon beasts that have naturally grown to a certain level in some areas of the Heart Demon Temple, and they will teleport to serve as guardian beasts. One is to save energy, and the other is to save the prohibition of killing these demon beasts that are about to grow to the point of harming their disciples.

Of course, whether or not the lightning can kill this fire bull demon beast, it is destined to not survive the day when the Heart Demon Hall closes this time. After all, it will take another hundred years to open, and maybe this fire bull will grow to the strength of the eighth or ninth layer in the foundation building period. The designer of this Ancient Sect's Heart Demon Hall can be regarded as painstaking, thoughtful and meticulous, and makes the best use of things. It's only occasionally that I'll suffer from bad luck like Lei Dong. After all, a real demon beast with sixth-layer strength is different from a summoned beast condensed by spells.

At the same time that the Critical Ghost Guard was knocked away, Lei Dong immediately ordered the other two Ghost Guards to withdraw immediately, and they were not allowed to fight with it. The difference in strength between the two sides is too great, and hand-to-hand combat is simply looking for death. Taking a deep breath, ten thousand ghost flags were sacrificed, and hundreds of powerful ghosts surged out, forming an astonishing and terrifying roaring ghost tide.

Of course, Lei Dong didn't point at these powerful ghosts to kill this sixth-layer Purgatory Fire Bull Demon Beast, if he wanted to rely purely on powerful ghosts to kill demon beasts of this level, I am afraid it would be difficult to do it without thousands of powerful ghosts. What Lei Dong wants is just to let this group of powerful ghosts contain it.

The black qi around his body surged, and at the same time as the Nether** was unfolded, the thunderous body flashed again and again. At the same time, Lei moved his hand to duel the law, and a football-sized, green fireball with a long flame tail smashed straight towards the fire bull. The fire bull is worthy of being a demon beast rather than a spell summoning beast, and with such a huge body, it actually twisted and jumped vigorously, dodging the thunderous fire bomb.

The Dark Fire Bullet, since Lei Dong cultivated this spell, has always been rarely used. But at this moment, it is used to deal with this fire bull, not without reason. The purpose of the thunderbolt was only to get the attention of the fire bull, not to kill it. If you use the Falun of Annihilation, not only is it impossible to kill it so easily, but the cost is too great.

From the moment he retired from the ghost guard, Lei Dong knew that this was a protracted war of attrition.

The thunderous fire bomb does not reach home in cultivation, the speed is slow, the cohesion is poor, and the power cannot reach the general lethality of the monks in the foundation building period. There is no way, if any spell is to be used well and become a killer weapon, it must go through a lot of time and continuous practice before it can gradually become proficient. But Lei Dong really doesn't have much time for him to cultivate the Hellfire Bomb for a long time. Lei Dong is not proficient in the control of the Dark Fire Bomb, and it is not a big problem, with his cultivation as a divine thought, it is still possible to temporarily detonate the Dark Fire Bomb.

It was at the same time that the fire bull dodged the fire bomb, and it exploded. The green fire, with the blessing of the ghostly aura, is like a huge wave. Sparks bloomed, splattering outwards in all directions. Although the fire bull dodged the Hellfire Bomb, it did not dodge the explosion. But whether it was the shock wave formed by the explosion or the splashing flames, they were blocked by a layer of flames on the surface of the fire bull's body, and they couldn't hurt it in the slightest.

But the fire bull was completely enraged by the thunder. let go of the ** that continued to attack the crit-hit ghost guard, and instead rushed towards the thunder. The momentum is fierce and unusual. As for Lei Dong, he stepped on the ghostly spirit, and his body swept past the afterimages, and he began to hide and hide with the fire bull. The fluttering of thunder, the ferocity of the fiery ox. intertwined. It was also thanks to the entanglement of hundreds of powerful ghosts and ghostly ghosts that Lei Dong could barely avoid the fire bull from time to time.

In a moment, the fire bull was even more arrogant.

"Moo~"

A deafening roar arose, and the fire around the Infernal Fire Ox burst into flames, gathering into a single flame, like a dragon's teeth and claws, and rushed towards the thunder. The legs of the thunderous volley did not stop, and with a pinch of the magic trick, a cold and cold transparent cover suddenly formed on his body. At the same time, the ghostly aura around him also condensed, sweeping towards the surging flames.

Boom~ The two sides collided, and a wave of air erupted, which shook the air and made a deafening blasting sound. Although Netherworld is one of the top in the world, Lei Dong's cultivation is not enough. This is a hard-hitting confrontation. The ghostly aura only lasted for a few breaths before it was dissolved. The remaining surging flames were like extraordinary power rolling towards thunder.

Thunder moves and flies, like a ghost soaring in the night sky. The tongue of fire continued to encroach on his body, but it was blocked out by the Xuanyin shield one by one. It was also thanks to Lei Dong who used the Nether Ghost Qi to block it, and the power and momentum of the flames dissipated half of Tai. This makes the Xuanyin shield barely able to support it. A moment later, the aftermath of the flames dissipated. And the thunderous Xuanyin shield also cracked, and the hair was curled a little.

After the Purgatory Fire Bull burst out of the trick just now, the fire on his body also dimmed a lot in an instant, and he became out of breath. When chasing the thunder again, the movements are no longer as agile and powerful as before. Not only him, under the fierce escape and engagement, the power in Lei Dong's body also consumed half of Tai, and it was very tight. But fortunately, he is used to using the Heavenly Demon Transformation to assist in cultivation on weekdays, and now he is still far from the feeling of exhaustion and being drained after the Heavenly Demon Transformation, and he can still persevere. Now, he had just swallowed a Qi Rejuvenation Pill, and he didn't know when he was already holding a high-grade spirit stone in his right hand.

Although he can't quickly absorb the spiritual energy in the top-grade spirit stone to replenish his consumption, he holds a high-grade spirit stone in his hand and does not lose his luck to absorb it. The abundant and pure spiritual power in it will also slowly infiltrate and advance, which will be somewhat beneficial to Lei Dong in a long-term war of attrition. If the ghost guards scattered nearby and hidden at this moment stepped forward to close the circle, they would already be able to kill the fire bull whose physical strength and demon power consumed half of Tai. But the thunder was still erratic, continuing to seduce, consuming the physical strength of the fire bull. Originally, he had a hard time dodging.

But at this time, it is much less labor-intensive than the earliest. Lei Dong can already dodge while silently absorbing the spiritual power in the high-grade spirit stone. His face was solemn and silent.

Half an hour.

An hour later.

At this moment, the thunder movement slowly restored his true qi to the level of seventy or eighty percent on weekdays. And the Purgatory Fire Ox, after the thunder spent a lot of time and energy, was finally dragged to the point of almost collapse, gasping in the sinuses, and the four hooves began to run weak. If it weren't for the stubbornness of the fire bull himself, he would have run away a long time ago, and he would have been too lazy to continue to entangle with this perverted human being.

It was only at this moment that Lei Dong summoned the three ghost guards that had been hidden for a long time and began to close together. At the same time as the ghostly aura was flourishing, the three ghost guards showed a terrifying and hideous momentum. Under the siege of Qi Qi, in a short time, the huge fire bull that was exhausted and did not have much strength was divided. Lei Dong took out a spare soul sealing bead and sealed the vivid, translucent and miniature version of the fire bull beast soul of this demon beast purgatory fire cow into the soul sealing bead.

As for the three ghost guards, they were full of excitement, turning into three dark and terrifying, cold ghost mist, which directly wrapped the flesh and blood of the corpse of the fire ox and devoured it. Because of sucking flesh and blood, the three dark black fogs gradually turned scarlet, bloody and cruel. Accompanied by the excited squeaky ghost roar of the three ghost guards, piercing and disturbing. If someone who doesn't know why sees it, they may faint in fright.

At this moment, the beam of light flashed away. Left behind a thing, Lei Dong took it and took a look, his face was slightly disappointed. This should be the last guardian beast in the Black Tower, and there is a chance that it will appear Heartwash. But at this moment, the black and crystal ore in Lei Dong's hand is obviously not compatible with the heart washing fruit.

"Come out~"

After doing all this, Lei Dong began to admire the three ghost guards eating with his hands behind his back. But at the same time, he said in a cold and deep voice.

However, nothing happened.

Lei Dong sneered, and a cruel smile appeared on his face: "Qi Feifei, don't force me, force me to kill you." ”

"Giggles. ”

A series of crisp laughter like silver bells sounded, a red shadow swept by, and Qi Feifei's slender and sexy delicate body appeared directly seven or eight feet away from the thunder. Although he was smiling, his fair and pink face was a little pale at the moment, and he smiled forcibly: "Senior Brother Lei, don't be angry, little sister didn't deliberately step aside." I just want to see if Senior Brother Lei can kill this Purgatory Fire Bull alone, people don't have any bad intentions. But as he spoke, he looked at the ghost guards who were devouring flesh and blood in an extremely disgusting way, and his face became more and more pale. She was not afraid of the bloody appearance devoured by the ghost guards, but she was afraid of the strength of those ghost guards, to put it bluntly, she was afraid of the strength of thunder.

"Hmph, Qi Feifei. I, Lei, am not a headless and brainless fool, and I will be fascinated by you casually, and I can't distinguish between the southeast and the northwest. Lei Dong snorted coldly and looked at her murderously: "I know you have been waiting for an opportunity, but unfortunately, after waiting for a long time, you haven't found a chance to be sure." ”

"Senior Brother Lei, you misunderstood others. Qi Feifei's face stiffened, and she began to perform her best charms, with autumn waves and body fragrance.

"Stubborn, you are looking for death!" Lei Dong's face showed anger, and the three ghost guards immediately stopped devouring and eating. Qi Brush condensed into shape, scarlet, and killed Qi Feifei.
