At this moment, in the Black Iron Castle, everyone heard the angry roar of the demon monitor lizard.

"What kind of sound is that?" The disciples of the Dan Dao Sect in the Black Iron Castle were all talking, and they could hear the roar of the monster in the past, but there was no such horror, and ordinary people could hear the anger in that voice.

"Demon monitor lizard?" Zhao Xiao, who was patrolling the castle, couldn't help frowning when he heard it, the demon monitor lizard has the most territorial concept, as long as you don't mess with it, it will definitely not come to mess with you, plus the Black Iron Castle has more than enough defense, and the attack is insufficient, Zhao Xiao will think about the idea of killing the demon monitor lizard.

Zhao Xiao stood on the city wall, holding the battlements with both hands, and his deep gaze penetrated the darkness, as if he wanted to see what was going on there.

There are no other large creatures in the ground except for monitor lizards, he really can't think of anyone who dares to provoke monitor lizards, the demonic beasts in the Dan stage are not something ordinary people can imagine, every move is terrifying, even Zhao Xiao, a cultivator who is about to reach the Dan stage, is not sure.

After looking at it for a while, he turned around and asked, "Senior Brother Qian Chengming has been gone for a few days, has there been any reply?"

"Nope. "The men report.

"There's no news yet, this can't be!" Zhao Xiao muttered, Qian Chengming led the team to rescue Zhang Xuan, but he had not been seen for so long, and there was no one who came back to report the news, and he had a bad feeling in his heart.

"Senior Brother Zhao, if you have sorrow in your heart, I can help you calculate ......" At this time, a handsome guy walked up, only to see him with sword eyebrows and starry eyes, extremely handsome, and exuding the unique aura of a cultivator.

He is the inner disciple Ouyang Mu, this person specializes in mathematics, and he is particularly good at pinching his fingers and telling hexagrams, and his hexagrams are particularly effective, and he has only come to serve in Black Iron Castle in the past few days.

"Oh, then there is Senior Brother Lao Ouyang. When Zhao Xiao saw Ouyang Mu, he couldn't help but smile and said, he was convinced of Ouyang Mu's hexagram.

"It's okay!" Ouyang Mu said with a smile, and for a moment he became serious.

I saw that his slender fingers were like phantoms, constantly pinching his fingers, as time passed, his hands emitted a faint light, Ouyang Mu's brows were sometimes furrowed, sometimes loosened, and Zhao Xiao's mood also rose and fell with Ouyang Mu's expression.

Ouyang Mu sighed and said, "If I'm not mistaken, Senior Brother Qian Chengming and Senior Brother Zhang should have this catastrophe in their fate, I'm afraid they have already ......."

Zhao Xiao was taken aback when he heard this, how could he not understand Ouyang Mu's words?

"This ...... How is this possible?" Zhao Xiao said with a bitter mouth.

"There is nothing impossible, today is a fierce dog eating the moon, dangerous and abnormal, dangerous in the southeast. And the southeast where the two of them happened to go is a great omen!" Ouyang Mu said with an ugly face.

Before Zhao Xiao could speak, Ouyang Mu seemed to remember something, his face became a little pale, and he continued to pinch his fingers.

"Zi Chou Yin Mao ......" The more he calculated, the more ugly his face became, until finally, Zhao Xiao obviously saw that his face turned pale, a mouthful of blood spurted out, and he fell backwards on his back.

Frightened, Zhao Xiao hurriedly supported him, and when he looked at it, he found that Ouyang Mu's face was like gold paper, his eyes were closed, and he was obviously unconscious. Zhao Xiao hurriedly helped him sit on the ground, massaged him, and then fed a few pills, and for a long time, Ouyang Mu slowly opened his eyes.

"What's wrong with you, don't scare me," Zhao Xiao said anxiously.

"It's okay......" Ouyang Mu said with a wry smile and shaking his head, he sat up with difficulty, panting.

"What the hell is going on?"

"Alas, I calculated the fate of you and me just now, and found that they are all great omens, and it is a bloody disaster, when I was studying mathematics before, the master told me that when I was 130 years old, I had a catastrophe, if I can't pass this catastrophe, Shouyuan will end here, I will be 130 years old this year......" Ouyang Mu said with a sigh, Zhao Xiao's face became more and more ugly when he heard these words, the disaster of blood light?

It's no wonder that his eyelids are beating wildly these days, and he always feels that something is going to happen.

"I wonder if it can be broken?"

"This ...... I still remember my master once said that if you want to survive this bloody disaster, you need someone to ......"

"Someone, who is it?" Zhao Xiao asked anxiously.

"My master didn't explain it, he only said that everything was a chance," Ouyang Mu said with a bitter face......

"I know, I will send someone to find out the situation, Senior Brother Ouyang, you have worked hard, go down and rest first!" Zhao Xiao said gently.

"En!" Ouyang Mu sighed and nodded, Zhao Xiao hurriedly asked someone to escort Ouyang Mu away from the city wall, he turned around and still stared outside, and said for a long time: "Pass my order, all teams stop patrolling and expedition missions, and the first team will immediately set off and go to the Yin Feng Cave to find Senior Brother Qian Chengming and Senior Brother Zhang, and be sure to find out whether they are alive or dead." ”

"Yes!" Several disciples who had been on standby hurriedly went to answer the order.

"Why are all the tasks canceled, what's going on?" Hearing Zhao Xiao's order, the disciples of the Black Iron Castle were all talking, and most of them were here for the high contribution task.

"Yes, cancel the task, I'm still waiting to earn contributions and exchange them for magic weapons?"

"Yes, could it be that it has something to do with the call of the monitor lizard today?"

"I don't know, maybe this year's gray tide came earlier......." everyone speculated.

Zhao Xiao knew that he had to find a reason to appease everyone, and his voice spread throughout Black Castle and said: "Since the gray tide is ahead of schedule this year, Black Castle is on first-level alert, please be vigilant." ”

Sometimes people are herd, Zhao Xiao explained, everyone came to their senses, and they all got busy, only a few people who knew the inside story smiled bitterly, such as Ouyang Mu, who was meditating and pranayama, he slowly opened his eyes and sighed, and continued to meditate.

The first team quickly left the Black Iron Castle and disappeared into the night, this first team was composed of ten experienced inner disciples, they were all at the level of the foundation building stage, and they moved extremely quickly, and soon came to the Yin Wind Cave, trying to find clues.

It has to be said that they are sophisticated, and they quickly find some clues. An inner disciple named Li An is good at the light rejuvenation technique, and after performing the spell, he can clearly know what happened in a week, but unfortunately the consumption is extremely high, and it takes a long time to use it once.

They quickly followed the clues to the big rock.

"They finally stayed here......" Wang Ming, the leader of the first team, squatted down and twisted the dirt, he turned his head and nodded to Li An.

"Returning to the light!" Ang Lee walked over, pulled some powder out of his pocket, and carefully drew a circle on the ground, while the others looked around vigilantly.

What they didn't notice was that in the crack not far away, there was a mouse with green eyes, and the mouse was staring at several people.

As if aware, Wang Ming turned his head to look in that direction, and didn't care when he found out that it was a mouse, but he didn't expect that the mouse had already reported the information here to the ghost mother.

"Monk of Black Castle?" was chasing the ghost mother and was stunned, he didn't expect Black Castle to notice, he stopped after thinking about it, called Meng Tiandong, told him about this matter, let him deal with it, and find a way to take Black Castle.

"Guaranteed to get the job done. Meng Tiandong was stunned at first, and patted his chest with great joy and said. Although he couldn't catch Zhang Yu with his own hands, which was very depressing, but he could destroy the Black Castle, I don't know why, Meng Tiandong felt a certain pleasure in his heart.

"Go, take all the people with you......" said the Ghost Mother.

"Yes!" Meng Tiandong bowed his hand respectfully, turned around and left with the puppet.
