The prisoner grabbed his face with his hand, and in a moment his whole face was rotten, turning into pus and blood and dying on the spot, this was simply a provocation to the person present, Chi Guoguo, and the other prisoners were even more crazy and scolded, and the others were not only not afraid, but were ready to step forward to kill Meng Tiandong.

"I'm coming!" Qiu Chengfeng shouted loudly, his fists were already itchy, he snorted coldly, and disappeared in place.

Instantly flashed in front of Meng Tiandong and smashed his jaw with a punch, Meng Tiandong screamed miserably, fell backwards, and hit the wall like a cannonball, making a sound of bones shattering.

Knowing that Meng Tiandong was like a monster, he got up again and flew over, and in an instant, the two of them didn't know how many rounds of fighting.

I have to say that this made everyone's scalp tingle, that Meng Tiandong's neck was twisted by Qiu Chengfeng, and he was able to break it and continue to rush up.

The footsteps started again, and Zhang Yu rushed in at this time, just in time to see Meng Tiandong smashing away again.

Seeing Zhang Yu, Meng Tiandong was like seeing an enemy, his eyes were red and he roared, turned around and pounced on Zhang Yu.

Zhang Yu frowned and sighed, only to see a black shadow behind Meng Tiandong, and that black shadow controlled Meng Tiandong's behavior.

Throwing Meng Tiandong over, he dodged slightly, a rune flashed out in his hand, and turned around and stuck behind Meng Tiandong. I saw that Meng Tiandong seemed to be hit by a soldering iron, stretched out his arm and desperately grabbed his back, making a scream that did not look like a human being, and then a humanoid flame appeared behind him.

A terrifying skeleton appeared, turning into a cloud of black smoke and disappearing without a trace.

"Zhang Yu!" seemed to feel something, the ghost mother standing on the monitor lizard gritted her teeth, he was originally going to make the inside of the Black Castle bloom, but he knew that Zhang Yu actually killed Meng Tiandong.

He looked at the boundless underground creatures around him, waved his hand violently and shouted, "Attack!"

With the order of the ghost mother, countless underground creatures rushed towards the Black Castle in unison, making people's scalps tingle.

"It's coming!" Zhao Xiao felt the pressure increase greatly, he clung to the wall with both hands, and the solid masonry was crushed by him.

Heavy prison.

A group of people looked at Zhang Yu in a daze, they couldn't imagine that such a strange person was killed by Zhang Yu at once, and their eyes showed a glint of awe.

Qiu Chengfeng's eyes were particularly complicated, but the strong in this world were respected, and he had nothing to scruple about, so he hurriedly stepped forward and respectfully bowed his hand: "Boss, why are you here?"

The others hurriedly nodded and ran over to say hello, and Zhang Yu nodded.

"It's been a mess out there lately, so stay here if you're fine!" Zhang Yu has a good impression of this group of people, much better than those who cheat me.

"Okay!" Hearing Zhang Yu's words, Qiu Chengfeng was slightly stunned and nodded, I don't know what's going on, Qiu Chengfeng still believes in Zhang Yu in his heart.

"Okay, okay, it's just a routine inspection, let's go back!" Qiu Chengfeng said loudly, although the others were a little confused, they still slowly returned to their prisons.

Zhang Yu saw those prisoners leaving, so he went over to look at Meng Tiandong, only to see that his bones were broken, his mouth was spitting blood, and he was already dying.

Zhang Yu touched his pulse and found that his internal organs were broken, Meng Tiandong looked at Zhang Yu and was speechless.

"Alas, don't be a traitor in the next life. Zhang Yu sighed, and before he finished speaking, Meng Tiandong exhaled his last breath deeply.

Meng Tiandong's death was to blame, Zhang Yu shook his head, he grabbed Meng Tiandong's body and said hello to Qiu Chengfeng, and walked up.

As soon as he walked up to the first layer of the prison, he heard the sound of chaotic footsteps, Zhang Yu became vigilant, and he couldn't help but breathe a sigh of relief when he saw Zeng An break in with a group of cultivators.

"Are you okay?" Zeng An couldn't help but be overjoyed when he saw Zhang Yu, he couldn't help but breathe a sigh of relief when he looked at Meng Tiandong's corpse.

"It's okay, Meng Tiandong was controlled by the people of the Ghost Domain......" Zhang Yu recounted what had just happened.

"Since it's okay here, and the walls are tight, let's go. The inner disciple who led the team said that since the prison guards were all dead, he left a few cultivators to maintain the barrier, and the rest turned around and left.

"Is the wall tight?" Zhang Yu asked.

"There are too many underground creatures, the gravity circle outside the castle can last for more than half an hour at most, by the way, Senior Brother Zhao asked you to meet him. Zeng An suddenly remembered something and said to Zhang Yu.

"Okay, I'll go right away!" Zhang Yu nodded, handed over Meng Tiandong's body to Zeng An for disposal, and hurriedly walked out of the prison.

As soon as I walked out of the prison, I heard fierce shouts and killings, countless people carrying supplies, spells flashing in the sky, and various screams were heard from time to time, and the entire sky above Black Castle was full of tension.

Zhang Yu couldn't help but feel slightly relieved, at least so far, there were no casualties, and he didn't stop, and flew quickly to the main hall.

When he came to the main hall, he unexpectedly found that Zhao Xiao, Ouyang Mu and several other inner disciples were saying something with serious expressions.

Seeing Zhang Yu coming, Ouyang Mu nodded with a smile, and Zhang Yu hurriedly returned the salute.

"Something happened in the prison?" Zhao Xiao asked when he saw Zhang Yu coming.

"Yes, Meng Tiandong was possessed, and he also controlled everyone in the prison......" Zhang Yu recounted the process, and everyone who listened was apprehensive.

This made Zhao Xiao sweat and shouted luck, if Zhang Yu and Zeng An did not arrive in time at that time, let Meng Tiandong control all the people in the prison and destroy the formation inside the Black Castle, at most one day the Black Castle would be lost.

"I really want to thank you this time!" Zhao Xiao took a deep breath and said to Zhang Yu sincerely.

"They are all people of the same family, so why bother saying this. Zhang Yu said with a smile.

Hearing this, Ouyang Mu nodded with a smile beside him, it seems that he is good, fortunately he released Zhang Yu in advance, otherwise the consequences will be unimaginable.

"Okay, since everyone is here, let Senior Brother Ouyang tell us about the current form......" After chatting for a while, Zhao Xiao loudly attracted everyone's attention.

"Ahem, let me tell you, the people of the Ghost Domain caught us off guard this time, the Ghost Mother summoned an endless number of underground creatures, the gravity formation supports a maximum of one day, and the outer enchantment can also support a maximum of a few hours, even if we kill these cannon fodder, it is useless, we don't understand if there are other hidden forces in the Ghost Domain, such as ......" Ouyang Mu paused as he said this.

"What hidden power?" asked an inner disciple curiously.

"The fellow disciples and brothers who were taken away by Zhang Duan, they are all the same as Meng Tiandong, ala......s" Ouyang Mu sighed, and the inner disciple understood, and his face changed.

Imagine that a large number of disciples who had known each other before would use knives against you, which would definitely cause a large number of casualties, and the Black Castle would be in danger immediately.

Everyone's faces were not good-looking, and at this time Zhao Xiao broke the silence and said: "We can't be so passive and defensive, I don't know if you have any ideas?"

"Anyway, it's all death, I'm afraid of a bird, let's kill it and kill the ghost mother!" a grumpy inner disciple stood up and shouted loudly.

"Yes, yes, I'm afraid of a fart!" Fortunately, the people who have been underground for so long are not weak, and they all yelled.

Morale is available, Zhao Xiao nodded with a smile, and he frowned in a moment, there are too few people in the Black Castle, and if you kill it, you may be overwhelmed by those monsters in an instant, you must know that those monitor lizards have not yet fought.

"I don't know if Senior Brother Zhang, do you have any solutions?" Ouyang Mu, who had been silent, suddenly asked.

"Me?" Zhang Yu was stunned, not understanding why Ouyang Mu would ask him, he just wanted to say that there was no way, but a flash of inspiration suddenly flashed in his mind, and he blurted out: "I have an idea." ”

"Oh, what do you think, can you say it and listen to it?" Zhao Xiao asked curiously.
