With his current strength, it wasn't difficult for Ling Yun to complete the challenge on the sixth floor of the pagoda. He wanted to move on to the next floor, but he had to wait until his cultivation broke through to the Supreme Realm first.

Ling Yun opened the golden chest that appeared after the challenge ended, finding a book inside. He took it and read the title. "Absolute Yin Sutra?"

[Absolute Yin Sutra: This technique is a supreme dual cultivation scripture specifically for female cultivators, created by an Ancient Heavenly Maiden who understood the origin of Yin within the universe. Unlike ordinary dual cultivation techniques that rely on mutual exchange, this technique allows female cultivators to refine and transform Yang Qi into pure Absolute Yin.]

"An ancient heavenly maiden? Pure absolute Yin?" Ling Yun immediately read the technique carefully. "The female cultivator does not merely harmonizes with her partner; she absorbs and purifies her partner's Yang Qi, turning it into absolute Yin Qi. The stronger her partner's Yang Qi, the greater the benefit. Her body becomes a living furnace, where Yin Qi circulates endlessly, purifying every Yang Qi she absorbs without any impurities."

[First stage: Opening the Yin meridians, the body becomes softer, and the aura becomes more alluring.]

[Second stage: Skin becomes flawless like jade.]

[Third stage: Aura becomes enchanting, gaining control over emotional influences.]

[Fourth stage: Forming a condensed Yin Qi core so that the efficiency of dual cultivation increases drastically.]

[Fifth stage: Controlling the Yin Qi in the surrounding environment; the user can absorb Yang Qi from men without touching them.]

Ling Yun sucked a deep breath after reading that. In his opinion, the physical changes that occurred from the first to the third stages were insignificant because all of his wives had unmatched beauty. However, he had no idea about the Yin meridians and Yin Qi core, but he felt that both were different from the original meridians and cultivation core. As for the fifth technique, he felt that the ability to control the Yin Qi in the surrounding environment was extraordinary, but he didn't want all of his wives to absorb Yang Qi from other men.

Ling Yun immediately left the pagoda and went to meet Sheng Ming, who had woken up from her long sleep. "Ming'er."

"Hmm? What's wrong, husband?" Sheng Ming looked at him with a puzzled expression.

"Have you ever heard of the Absolute Yin Sutra and the ancient heavenly maiden?"

Sheng Ming's expression changed slightly. "Where did you hear about those two names?"

"Here." Ling Yun handed the Absolute Yin Sutra to her. "I got it from the sixth floor of the pagoda."

"I see," Sheng Ming said as she read the technique. "The ancient heavenly maiden was once one of the ancients, and she was much older than the ancestor of the Zhizun Clan. In the past, her clan was the Great Celestial Clan, but it had long been destroyed, and all its members were wiped out."

Ling Yun raised an eyebrow. "How could the clan be destroyed? Who destroyed it and wiped out their members?"

"Why don't you ask the dragon in your body?"

"Old dragon who destroyed that clan and wiped out their members?" Ling Yun was shocked.

"That's right." Sheng Ming nodded. "Don't you want to come out and explain everything to your heir, Long Hun?"

"Haish," Long Hun sighed after emerging from Ling Yun's body. "The ancient heavenly maiden was once Shangguan Tiannu, and she was one of the women who was close to me in the past, just like Tai Yiqin. As you know, I am the best at understanding the origin of Yang within this universe, and I was the one who guided her to create the Absolute Yin Sutra. At first, everything went without problems, but she kept changing, and she was addicted to using the fifth sub-technique in that technique."

"You mean she used the fifth sub-technique to kill the men by absorbing their Yang Qi?"

Long Hun nodded. "She killed a thousand men in a day by absorbing their Yang Qi until it was clean. At first, I let her do as she pleased because all her victims were evil cultivators, but her victims continued to increase as time went by, and she began to kill many innocent cultivators. I had persuaded her to stop her actions, but she was unwilling to listen to me and tried to absorb my Yang Qi."

"What a foolish woman," Ling Yun said, shaking his head. "Even if she were an ancient being, she couldn't possibly absorb your Yang Qi, and her body would explode if she absorbed too much."

"That's right." Long Hun let out a regretful sigh. "She used to be a very kind and gentle woman, and I shouldn't have helped her create that technique in the past. Since she had changed and wouldn't listen to my words anymore, I was forced to kill her, and I also destroyed her clan. I had already destroyed that technique in the past, but I didn't expect someone to recreate it and place it in the pagoda."

"Chaos." Ling Yun could only think of that name because he was omnipotent, and he controlled everything in the universe.

"I thought the same as you." Long Hun took the book from Sheng Ming's hands. "I don't understand why my father did that, but he seemed to have deliberately arranged for you to discover this technique. Sheng Ming and Luxuria should be able to learn this technique, and it shouldn't be a problem for them since they are the Life Goddess and the Lust Spirit. However, I do not recommend that you share this technique with your other wives, particularly the mortal women, as they may end up like Shangguan Tiannu."

Ling Yun took the book. "I don't know anything about Shangguan Tiannu, but I've always trusted all my wives. Even if they learn this technique, they will never act like that woman. Besides, we can erase or change the fifth stage, so they will never be able to learn it, right?"

"That's true," Sheng Ming agreed with him. "Since you helped Shangguan Tiannu to create the technique, you should be able to modify it, right? Even if you can't do it in your current condition, you can guide me to change the fifth stage of the technique, so it won't be harmful to my sisters."

Long Hun considered it for a moment before agreeing. "Alright! I'll guide you to modify the fifth stage of the technique, and they won't be able to absorb Yang Qi from other men."

"That's great."

Ling Yun left Long Hun and Sheng Ming in the room, and he went to see Jin Nanyi. After all, he was the only one who could approach her because of her Poisonous Unapproachable Body, making her often feel lonely.

"Why did you come here?"

"Don't you want me to accompany you?" Ling Yun sat beside her. "How is your cultivation? Are you close to breaking through to the Three Immortal Realms?"

Jin Nanyi sighed, shaking her head. "Even though I've been cultivating using your dual cultivation technique and Yang Qi, my cultivation still seems to be far from the Three Immortal Realms, so I can only be patient and cultivate harder. Are you going to enter seclusion again in the near future?"

"No," Ling Yun answered by shaking his head. "Almost all of my wives went to the Trial Tower, and they only reached the second floor a few days ago, so they won't be returning any time soon. Besides, we've been in seclusion for decades, so I let them rest to hone their other skills."

Jin Nanyi nodded in understanding. "This residence has become deserted, with almost everyone going to the tower, and I'm feeling lonely too."

"Haha," Ling Yun laughed softly. "Didn't I say you could go out for a walk if you wanted? However, you decided to stay and focus on your cultivation, so don't complain about your own decision."

"I don't have anyone anymore, so I'll always be lonely wherever I go. Rather than wasting my time on such useless things, I'd rather focus on my cultivation." Ling Yun suddenly pulled Jin Nanyi onto his lap, causing her to panic. "What... what are you going to do?" 𝚏𝗿𝗲𝐞𝐰𝚎𝕓𝐧𝚘𝘃𝗲𝐥.𝐜𝚘𝕞

"Stay still." Ling Yun hugged her waist. "I won't do anything to you, and I just want to hold you like this."

"I—" Jin Nanyi didn't continue her words and placed her head on his shoulder. "I'm truly happy to have you by my side, and I've never felt this close to anyone else, Ling Yun. In the past, everyone close to me died because of the poison in my body, forcing me to live alone in the void. Although I've often been lonely all these years, I'm pleased that you always come to accompany me, even if you only use your clone."

Ling Yun felt sorry for her situation. "You may no longer have family out there, but you've lived in this residence for almost two decades, and you've become part of our family. If you need anything, you have to tell us, and we will help you."

"Ling Yun." Jin Nanyi hugged his neck as she shed tears. "Why are you nice to me?"

"There's no particular reason." Ling Yun rubbed her back. "In my principles, I will always treat all good people with kindness, and I will treat bad people with cruelty. Since you're not a bad person, I will always treat you well."

Jin Nanyi fell silent and pondered his words. "Have you ever thought about taking me as your woman?"

"Haha," Ling Yun laughed. "Wouldn't I be a hypocrite if I said I've never thought about it? However, I never made a move on you because you didn't want it, especially with dozens of wives by my side."
