Primordial 'Dual Cultivator' Dragon With System

"Who is that old demon?" Ling Yun asked Mao.

"Perhaps you all know that Lucifer is the leader of the Demon Realm, but he actually obtained his status by cheating." They were shocked to hear that. "Diablo is the true ruler, but they used underhanded methods to trap her; they then locked her up in the darkest place of the Demon Realm. Afterward, they used their combined techniques to erase her existence from the memories of all the demons, and none of them knew about her now, except for us Royal Cat Demons."

"Oh?" Ling Yun was taken aback for a moment and asked her. "So that's why Mammon slaughtered the Royal Cat Demons?"

"Yes." Mao nodded to him. "I don't know the reason myself, but our race was somehow unaffected by their techniques, so Lucifer ordered Mammon to slaughter us."

"Then why did Mammon let you live?" Ling Yun asked with a confused look.

Hearing that, Mao touched Zhao Yao's belly and used her demon power, making her feel a little strange in her body. "What are you doing to me, Mother?"

"Relax, Yao." Mao said this to her daughter and continued her action.

Soon, a black crystal ball shot out of Zhao Yao's mouth, causing her and Ling Yun to be stunned upon seeing that.

Mao immediately grabbed it and showed it to them. "This is Diablo's demon core; she gave it to my ancestor some time before Lucifer and the others captured her, especially since my race is her loyal servant. After I thought about it for so long, I came to the conclusion that this core is what made our race immune to their techniques. Before Mammon slaughtered my race, I put this into Yao's body and sent her to the human world to keep her and this core safe."

"Let me see it." Mao directly gave the demon core to Ling Yun, and he tried to scan it through his system, but the system didn't show any reaction. "I see, so only demons can use this core, huh?"

"Yes." Mao nodded to him. "That's why Diablo gave it to my ancestor, or else Lucifer will gain great power if he manages to get hold of this core."

Ling Xi suddenly appeared in front of them and snatched the demon core from Ling Yun's hand. "Since this core left her body long ago, I believe Diablo's strength has been drastically eroded. Even if she gets her demon core back, her strength won't be able to recover quickly, and she won't be of any use to us."

"That's true." Mao didn't deny Ling Xi's words, but she then said: "However, if Diablo manages to break free from that place and get her core back, then she can reverse their techniques, and the demons will remember her existence again. In that way, the demons who are now supporting the Demon Lords will surely rebel against them, and we can fight them without breaking a sweat."

"Wait a minute." Ling Yun interrupted Mao. "Before you do that, I want to know about Diablo's character first. I don't want you to release a person who is much crueler than Lucifer and the others, especially since she is the true ruler of the Demon Realm."

"Haha." Mao laughed at Ling Yun's words; she jabbed his chest lightly and asked him. "Do you still not understand why Lucifer and the others decided to trap and lock up Diablo?"

"Hmm?" Ling Yun shook his head at her.

"Diablo doesn't have the ambitions of Lucifer and the others, and she is already very satisfied with being the ruler of the Demon Realm." Mao explained as she smiled. "So you don't have to worry about her, and I dare to guarantee that she won't cause trouble in the human realm after she's freed from that place. Instead, the three realms will actually become more peaceful if she gets her status back."

Ling Yun did not blindly believe Mao's words; he then turned to Ling Xi. "What do you think about that?"

"I think there's no problem with that." Ling Xi then handed the demon core to Mao. "I'm sure Diablo will need at least hundreds of years to recover her strength, so she wouldn't dare mess with this world. Moreover, with your current strength, you can kill her easily, so you don't need to think about her."

"All right then." Ling Yun replied with an understanding nod. "However, it would be best if you didn't bring Layla back to the Demon Realm, or else Lucifer and the others would come after you two later."

Mao thought for a moment before nodding in agreement. "Okay, I'm not taking Layla with me, but I'm taking Zoe with me because she misses her family so much, so I'll take her to meet them."

"Okay." Ling Yun agreed with that, for he knew well about Zoe's concern for her family, so he didn't want to stop her from looking for them. "Anyway, you can also bring Duan Wu to the Demon Realm, and her Dimension Travel will be very useful there. Moreover, she can communicate with me at any time, so she can inform me directly if you guys are in any danger, and I will immediately go there to help you all."

"Okay." After that, Mao immediately left them, and Zhao Yao breathed a sigh of relief.

Ling Yun asked her. "Why are you sighing like that?"

"Humph!" Zhao Yao snorted at him and warned her husband sternly. "Yun'er! I don't want you to take my mother as your woman, okay? If you take her as your woman, I will ignore you forever!"

"Haha." Ling Yun laughed and pulled Zhao Yao into his arms, and he kissed her lips for a moment before teasing her. "Are you really able to ignore me, Yao'er?"

"Of course I can do it!" Zhao Yao said it with a serious look, but she added in her heart. 'Stupid husband! How could I possibly ignore you?'

Ling Xi laughed at Zhao Yao's thoughts, but she didn't say anything and disappeared from the control room.

"You know that I don't believe your words, right?" Ling Yun laughed in satisfaction, seeing Zhao Yao pout her lips. "We've spent a few years together, so I know you very well, and I know that you can never ignore me.

Zhao Yao became irritated and bit Ling Yun's shoulder with her sharp teeth, and her hand squeezed his dick hard.

"Hiss!" Ling Yun grimaced and said to her. "What are you doing? My dick will become paralyzed if you squeeze it that hard! And all of you will definitely suffer later!"

Upon hearing that, Zhao Yao immediately stopped her action and laughed, for she naturally knew what Ling Yun meant. "Hehehe! I won't do it anymore, or else you won't be able to satisfy us later."

"Hey, Yao'er! You're getting lustful now, you know?" Ling said as he lifted Zhao Yao into his arms, and she immediately put her arms around his neck. "But I really like this side of you, so how about we dual-cultivate now?"

"Yes, Let's-"

Zhao Yao had not finished speaking, but Xiao Yin had already walked in as she spoke. [Master! Everything is ready, so let's go to the laboratory now, and I will help you make the Mana Crystal in your body.]

They exchanged glances and laughed after hearing Xiao Yin, but Ling Yun didn't put Zhao Yao down and carried her away with him to the laboratory room.

Once they got there, Ling Yun sighed in his heart after he saw all the modern equipment, making Zhao Yao laugh with his expression. Ever since he became the owner of the Celestial Fortress, he hadn't toured the other areas himself, so he didn't know much about all the equipment inside that place.

[Master, lie down inside the capsule so I can start immediately.]

Ling Yun immediately put Zhao Yao down from his arms, followed Xiao Yin's instructions, and laid down in the capsule she was referring to. 'Sigh! Although he said that Tang Xiao isn't as strong as others, he possesses a lot of modern technology in his arsenal, and I am really lucky to own this Fortress now.'

[Master, the process will be a bit long and quite painful, so you must endure it.]

"All right."

Xiao Yin immediately started the process, and numerous needles stabbed into Ling Yun's body instantly, causing him to wince slightly, especially by the needles piercing the back of his hip.

Soon, Xiao Yin poured some strange colored liquid into Ling Yun's body, which made him groan from the pain coming from inside his body, and he could feel that all of those liquids started to gather not far from his dantian.

Gradually, the liquids begin to crystallize, but the process still takes a long time.

Meanwhile, Zhao Yao continued to watch her husband from the side of the capsule, but her expression looked worried upon seeing Ling Yun's expression, and she clasped her hands tightly, causing both of them to turn extremely red.

.

.

After several hours, the procedure was finally complete, and the capsule lid opened on its own.

[Ding]

[A Mana Crystal has formed within the Host's body.]

Ling Yun breathed a sigh of relief upon hearing the notification, and he immediately used his senses to check it out. "Hmm? Xiao Yin, why is my Mana Crystal similar to my Colorful Qi Core?"
