Lu Tianzheng's face sank, and he took out two red glittering talismans, threw them forward, turning into two palm-sized red firebirds, exuding an unbearable heat wave.

The two red firebirds spread their wings and pounced on the bone dragon's head.

There were two loud "booms", and the billowing flames flooded the bone dragon's head.

Lu Tianzheng's sleeves flicked, and a silver long sword flew out, and the silver light flashed, turning into a silver disc and sinking into the sea of fire.

With a "bang", the silver disc seemed to be blocked.

Lu Tianzheng pinched the trick with one hand, and hundreds of silver sword qi flew out.

At the same time, the others either sacrificed magic weapons, or threw powerful talismans and smashed them on the bone dragon's body.

For a while, the explosion continued, and all kinds of spiritual light were blazing.

A black light erupted from the flames, extinguishing the flames.

The bone dragon's body was intact, and its breath was slightly wilted.

Its long tail swept suddenly, turning into a white light and sweeping towards Wang Hu.

Wang Hu's face changed, and his body hurriedly rolled forward and dodged.

With a miserable scream, a disciple of the Taixu Sect who was close to Wang Hu was swept by the bone tail, and immediately flew upside down, slammed into the stone wall, and fell heavily.

This disciple of the Taixu Sect was bleeding profusely, and his breath was completely empty.

Lu Tianzheng frowned, and in the blink of an eye, three of his fellow disciples died tragically at the hands of the bone dragon.

As soon as he raised his right hand, two golden talisman seals flew out, turning into two golden rays of light and flying towards the bone dragon.

The bone dragon's huge claws grabbed forward, trying to grab the two golden rays of light.

With a few "poof" and "poof" sounds, two golden rays of light burst open, turning into countless golden threads, entangled the limbs of the bone dragon.

"Everyone, retreat, the golden silk charm can't trap this demon for long. Lu Tianzheng hurriedly shouted loudly.

Hearing this, Chen Ming's lips moved slightly, the blue light flashed under his feet, and he quickly ran outside the grotto, followed by Chen Xing'er and Li Feng.

Shi Yue heard Lu Tianzheng's shout and walked out of the grotto quickly.

At this moment, a burst of black gas came out of the bone dragon's body, and the golden threads wrapped around its body collapsed one after another, and the bone dragon regained its freedom.

The long tail of the bone dragon swept suddenly, and swept towards Wang Hu like lightning.

Wang Hu's face changed greatly, and he hurriedly rolled forward.

With a "bang", there was an extra groove several inches deep in the position where Wang Hu was standing.

At this time, the bone dragon blocked the exit of the grotto, and Shi Yue, Lu Tianzheng, and Wang Hu were trapped in the grotto.

The bone dragon's body twisted and pounced towards Shi Yue.

Shi Yue's face changed, the blue light flashed under his feet, and he retreated into the stone room.

The bone dragon followed and flew into the stone chamber, its huge bone claws slapping towards Shi Yue.

Shi Yue was so frightened that his soul flew out of the sky, and he hurriedly injected mana into the palm bead, his body shook and disappeared, and a blue bead fell to the ground.

With a "bang", the bone dragon's claws slapped on the blue beads, which were buried deep in the earth.

Taking advantage of this opportunity, Lu Tianzheng and Wang Hu rushed out of the grotto and ran along the way they came.

It didn't take long for them to catch up with Chen Xing'er and the others.

"Senior Brother Lu, where is Senior Brother Shi!Why didn't Senior Brother Shi come out?" Chen Xing'er frowned slightly, and asked with some concern.

"Senior Brother Shi retreated into the stone room, and the bone dragon chased in, and Senior Brother Shi was probably killed. Wang Hu sighed, looking a little sad.

Shi Yue once saved his life, Wang Hu was full of gratitude to Shi Yue in his heart, but when he encountered a bone corpse, he had no choice.

"Oh no, that thing is coming, let's get out of here. Chen Ming saw the figure of the bone dragon out of the corner of his eyes, his face changed greatly, and he said in surprise.

After speaking, a blue light flashed under his feet, and the way in his eyes ran out.

Lu Tianzheng and the others rushed to the way they came.

It didn't take long for the five of them to rush out of the main hall and retreat into the original bluestone corridor.

The bone dragon was in hot pursuit, as if it was going to kill them all.

Lu Tianzheng raised his right hand, and a golden talisman flew out, turning into a golden light curtain, blocking the exit.

With a "bang", the huge body of the bone dragon slammed into the golden light curtain, and the golden light curtain shook slightly a few times.

The bone dragon kept hitting the golden light curtain, making a chaotic sound, and the light of the golden light curtain gradually dimmed, and it seemed that it was only a matter of time before the golden light curtain shattered.

Chen Ming didn't dare to stay for a moment, and rushed towards the road quickly one step ahead.

"Let's get out of here, if we wait for this beast to get out of trouble, then we'll be in trouble. Lu Tianzheng said in a deep voice.

After speaking, he took Chen Xing'er and the three of them back along the way they came.

A scream came from the front.

Lu Tianzheng was shocked in his heart, his sleeves flicked, and a golden bead flew out, turning into a thick golden light curtain, covering the four of them inside.

The four of them held a golden light curtain and walked slowly out.

After returning outside, Lu Tianzheng saw a headless corpse lying on the ground, Chen Ming's head rolling nearby, his face full of incredulity.

In this way, there are only four people left in the Taixu Sect, which can be said to have suffered heavy losses, and this result made Lu Tianzheng extremely sad and angry for a while.

And Liu He, Chen Feng, Li Yan and Song Buqian gathered together, looking at Lu Tianzheng and the others who had just escaped with cold expressions.

Strangely, their cousins have all disappeared.

"Song Daoyou, what do you mean by this, do you think that the people of our Taixu Sect are easy to bully?" Lu Tianzheng said in a cold voice.

"Hmph, what do you mean by asking us with the face? Let me ask you, what's going on with this Vajra Array Talisman?" Chen Feng snorted lightly, pointed to the golden light mask, and asked coldly.

"We just came out, how do we know who got this Vajra Array Talisman, I still have to ask you!" Lu Tian said with a calm face.

"Hmph, are you fools for us? You people from the Taixu Sect entered the passage last, and this Vajra Array Talisman was not lost by your disciples of the Taixu Sect, could it be that we lost it? A fierce look flashed in Song Buque's eyes, and he said in a cold voice.

"Believe it or not, we met a bone dragon that had undergone a corpse transformation, if you don't want to die, you should break the Vajra Formation Talisman and leave here first. Lu Tianzheng's face sank and said coldly.

"That is, if you don't believe, see for yourselves. Chen Xing'er nodded in agreement.

"There's a bone dragon? I'll go and take a look. Liu He frowned, and walked quickly towards the passage where Lu Tianzheng and the four of them came out.

It didn't take long for Liu He to come back, his face extremely solemn.

"Liu Daoyou, is there really a bone dragon?" said Song Buqian with a frown.

"Well, looking at its size, it may have been a fourth-level Jiaolong before it was born, and the body of the Jiaolong is notoriously powerful among demon beasts, even if it is its bones, it is far from being comparable to ordinary demon beasts. Liu He nodded and said with a solemn expression.
