"You have all worked hard, leave the city defense here to us! You all go down to recuperate! Huh? What about Zhao Xiao?" Elder Wu looked around at everyone, and unexpectedly found that Zhao Xiao was nowhere to be seen, he couldn't help frowning, you must know that Zhao Xiao is the best disciple of these generations, and coming to Black Castle to serve is also experience.

"He is still in a coma with serious injuries, and he will probably wake up in two days. Zhang Yu, who was in charge of treating Zhao Xiao, replied, he looked at Elder Wu slightly, only to see that he had a childish face, a fairy wind and bones, and a particularly strong aura, and he could vaguely feel energy fluctuations on his body.

"Hey, who are you? Why are you so faced?" Elder Wu looked at Zhang Yu curiously, the inner disciples were all familiar, but Zhang Yu was an unfamiliar face.

"He is Zhang Yu, the biggest hero of the defense of the Black Fort this time......" Before Zhang Yu could speak, Ouyang Mu next to him hurriedly replied.

"Oh?" Elder Wu heard that Zhang Yu had killed the ghost mother, and couldn't help but look at Zhang Yu curiously, only to see his sword eyebrows and starry eyes, his eyebrows were clear and beautiful, and there was a heroic righteousness between his eyebrows, which made Elder Wu look sideways.

"Let's go in and talk about it!" Ouyang Mu said with a smile, Elder Wu nodded slightly, and walked in with his hands behind his back.

"What the hell is going on, why is the Ghost Mother here?" asked Elder Wu, who was sitting in the middle of the main hall, he knew the simple situation, but he didn't know the details.

"That's the ......" Ouyang Mu sorted out his thoughts and told the whole story, starting from the end of the ghost domain people's possession of Zhang, and then Meng Tiandong's defection to the ghost domain to deceive everyone, causing the death of a large number of inner and outer disciples, etc.

Elder Wu's brows furrowed when he heard this, he couldn't imagine that things were so tortuous and confusing, and finally Ouyang Mu finished speaking, he looked at Zhang Yu next to him and said, "How did you kill the ghost mother?"

"I'm lucky, I killed the ghost mother in one fell swoop when he was seriously injured...... Zhang Yu respectfully said the matter, highlighting that Zhao Xiao blocked the ghost mother, and he was lucky to kill the ghost mother.

"Good job, I see you're tired too, let's go down and rest first!" Elder Wu said approvingly, Zhang Yu knew that they had something to discuss, nodded and turned to leave.

After he left the main hall, no matter what Elder Wu and Ouyang Mu said, he saw many cultivators coming one after another, to Zhang Yu's surprise, they didn't repair the Black Castle's defenses, could it be that they wanted to give up the Black Castle?

Zhang Yu really guessed correctly, he didn't find the spirit stone vein for decades, and many people from the Dan Dao sect thought that the ore veins here were exhausted, and the ore veins here could be collected for more than ten years, but the annual maintenance fee of the spirit stone mine was too high, coupled with the ghost domain incident, almost crippled the Black Castle.

Elder Wu learned that a vein had been found at the Lantian Transit Station, so he brought another voice to abandon the Black Castle.

Of course, this was just a proposal, and Elder Wu wanted to hear Ouyang Mu's opinion.

Originally, Ouyang Mu thought that Elder Wu was going to ask Zhang Yu's origin, but he knew that Elder Wu was actually abandoning the Black Castle, which made him unable to say the words he had prepared.

"Abandoned Black Castle?" Ouyang Mu couldn't help but be surprised, he was also very smart, and he knew what the sect meant after a little thought.

"I respect the meaning of the sect, do you want to inform Zhao Xiao of this matter?"

Zhao Xiao immediately took back to the sect for treatment, and immediately mined the ore veins, and after this place was abandoned, everyone went to the Lantian transfer station. Elder Wu nodded and said.

"But those prisoners ......," Ouyang Mu asked with a frown.

"Prisoners, hmph, let them fend for themselves, the current task of the sect is to search for ghost domain people and dig ore veins, and prepare for the next sect competition. Elder Wu said solemnly.

If it weren't for this ghost domain invasion, the sect might have sent a team to hunt down and kill those criminals, but now the ghost domain people are eyeing the side, making the sect walk on thin ice, afraid of being taken advantage of by the ghost domain people, and finally the Dandao sect elders decided to abandon the black castle and shrink the defense line.

This is good news for Zhang Yu, without the Black Castle watching from the side, the spirit stone veins found in the demon monitor lizard's lair can develop.

Elder Wu didn't pay much attention to Zhang Yu, in his opinion, Zhang Yu was just a lucky person, and he turned around and left after dealing with the matter here.

Of course, there are rewards, kill the ghost mother, Zhang Yu got tens of thousands of contributions, which is an unexpected joy.

Zhao Xiao came to his senses before leaving, and he couldn't help but be grateful when he knew that Zhang Yu had killed the ghost mother.

"I will definitely repay you when I return to the sect, but it's a pity that Black Castle ......," Zhao Xiao said gratefully before leaving.

"It's okay, I hope we have one more day to fight together. Zhang Yu said with a smile. Zhao Xiao nodded, and left with the disciple who escorted him.

At this moment, suddenly Ouyang Mu sent someone to find Zhang Yu and wanted to talk to him, I don't know why, Zhang Yu always felt that something was wrong, every time he saw Ouyang Mu's clear gaze, Zhang Yu felt uncomfortable, as if he had no secret to strip naked.

He still came to Ouyang Mu's house as agreed, and Ouyang Mu's complexion improved a lot after cultivating for a period of time.

When Zhang Yu came, he was making tea, and when he saw Zhang Yu walking in the door, he couldn't help but smile and said, "Sit!"

"This room is equipped with a soundproof barrier, and the words don't enter the six ears......" Ouyang Mu smiled, pointing something.

"What do you want to say?" Zhang Yu said vigilantly, frowning.

"Let's not talk about this yet, drink tea!" Ouyang Mu had an extremely accurate grasp of people's hearts, and he smiled and handed over a teacup.

Zhang Yu frowned and took the teacup, he could smell the fragrance of the tea, but he was in an extremely calm mood, he still had to come, and he didn't feel a little burdened.

The two of them lowered their heads with teacups and drank with concern, until Ouyang Mu couldn't help coughing, originally he thought that Zhang Yu would ask questions first, then he knew that Zhang Yu could endure loneliness than him.

"I have been learning mathematics since I was a child, and I know a little about the future, I originally thought that the ghost mother's attack on the Black Fort would be a catastrophe for us, and I would definitely die......," Ouyang Mu raised his head and looked at Zhang Yu.

"Oh?" Zhang Yu raised his eyebrows, and raised his head to meet Ouyang Mu's eyes.

"Then I know we met you......" Ouyang Mu smiled and raised his teacup and drank it all.

"Meet me?" Zhang Yu asked puzzled.

"What surprises me is that you don't seem to be from this world?plus the ghost mother is making trouble for you, this reminds me of a prophecy, the prophecy of the Six Dao Immortals, plus you are a Heavenly Master, can I say that you are the Holy Dao Heavenly Master in the prophecy of the Six Dao Immortals?" Ouyang Mu looked at Zhang Yu with blazing eyes.

"You can't be looking for the wrong person, where am I the Holy Dao Heavenly Master......" Zhang Yu couldn't help but smile bitterly when he heard this, he was the foundation building period cultivator, which sect was the Holy Dao Heavenly Master!

"Hehe, I can't be mistaken. There is one more thing, the group of prisoners ......" Ouyang Mu wanted to speak and stopped, but looked at Zhang Yu's eyes and told Zhang Yu, I know that there is a relationship between you.

"What's wrong with those prisoners?" Zhang Yu pretended to be stupid.

"That group of prisoners can't survive underground with that little material, and it is impossible for them to return to the surface in their current state, if there are resources, they may still survive, can I think that this group of prisoners can find resources that can survive, or is it a spirit stone vein?" Ouyang Mu said with a smile.

"What ......"
