• Lu Qing'an promised to arrange an artifact-refining room and provide He Hong with whatever materials he needed.

Xu Yunyi was astonished to learn how Lu Qing'an had transformed Lu Zixuan's cultivation and given both girls terrifying treasures. She left convinced that her brother-in-law was far more powerful and unfathomable than she had imagined.

• Xu Yunyi asked Lu Zixuan how her cultivation had changed, and Lu Zixuan explained that Lu Qing'an had advanced her by a major realm and converted her cultivation to Demonic Qi.

• Lu Miaomiao demonstrated the powerful armor Lu Qing'an had given her, including its ability to appear, disappear, and change color.
• Xu Yunyi reconsidered Lu Qing'an's strength and felt grateful that the girls had such a father.

Xu Yunyi reunited Lu Zixuan and Lu Miaomiao with a transmission from their mother and gave them messages she had recorded, while they remained hurt and unwilling to speak to their family. Xu Yunyi then asked Lu Qing'an to talk privately, leaving Xue Tianfei suspicious of their closeness.

• Xu Yunyi connected Xu Qingying's transmission, but Lu Zixuan and Lu Miaomiao stayed silent when their mother asked to speak with them.
• Lu Zhengran spoke with his sisters and boasted about his cultivation, prompting Lu Zixuan to claim she had advanced a major realm and received a powerful divine weapon.
• Xu Yunyi confirmed Lu Zixuan's claims were true, but Lu Zhengran and Xu Qingying initially doubted them; Xu Qingying advised her son not to compete with his sister.
• Xu Yunyi gave Lu Zixuan and Lu Miaomiao formations containing messages from Xu Qingying, and they tossed them onto the bed without destroying them.
• Xu Yunyi asked Lu Qing'an to speak with her alone, and Xue Tianfei questioned why she still called him brother-in-law.

Lu Qing'an reassured Xu Yunyi after she apologized for her family, then showed He Hong the divine weapons he had made and promised to introduce him to their creator. He planned a trip to the Heavenfall Demon Cavern to gather materials and help the younger members improve their physiques, while Xiao Qingyi and Xue Tianfei chose not to join.

• Xu Yunyi apologized to Lu Qing'an for her sister, Zhengran, and Xu Xuanyu, and Lu Qing'an told her to stop blaming herself.
• Lu Qing'an teased Xu Yunyi by asking her to stay with him, then accepted her apology when she asked to say goodbye to her family first.
• He Hong praised the divine weapons Lu Qing'an had given his daughters, and Lu Qing'an offered to arrange for their creator to teach him artifact refining.
• Xiao Qingyi told He Hong that no one in the Demon Domain dared disobey Lu Qing'an without getting beaten, leaving He Hong and Xu Yunyi stunned.
• Lu Qing'an announced that he would visit the Heavenfall Demon Cavern for materials and bring those below the Great Emperor Realm to a place that could cleanse their physiques.
• Xiao Qingyi and Xue Tianfei declined to go because their past experiences in the Heavenfall Demon Cavern had nearly cost them their lives.

Lu Qing'an took Xu Yunyi, Sun Minzi, and his daughters to the Heavenfall Demon Cavern to temper their bodies, warning them to stay within his protection. As they descended into the crater toward its depths, the Demon Domain cultivators watching from outside were stunned by their recklessness.

• Lu Qing'an asked Xiao Qingyi to contact Wang Duanshan for help building an artifact-refining room and promised to return soon.
• Xiao Qingyi tried to persuade Wang Duanshan to come, but Wang Duanshan suspected a trick and refused even after Xue Tianfei confirmed Lu Qing'an had returned.
• Lu Qing'an brought Xu Yunyi, Lu Zixuan, Lu Miaomiao, and Sun Minzi to the Heavenfall Demon Cavern, where he recalled finding the Immortal-Slaying Black Flame and surviving the deadly crater.
• Lu Qing'an warned the four to remain under his protection and told Lu Zixuan to watch over Lu Miaomiao.
• Lu Qing'an led the four into the crater and toward its depths, shocking the Demon Domain cultivators who saw them descend.

Lu Qing'an took Xu Yunyi and the children deep into the Heavenfall Demon Cavern, created a protected area where they could temper their bodies, then continued toward its unexplored depths in search of artifact-refining materials. At ten li deep, he sped past two Peak Great Emperor Realm experts who could barely descend, leaving them stunned.

• Lu Qing'an brought Xu Yunyi, Sun Minzi, and the children to a protected area about three li deep, where he filtered the flames to provide safe body tempering.
• Xu Yunyi and the children tested the tempering zones, and Xu Yunyi found impurities leaving her body and gained insights into cultivation and formation problems.
• Lu Qing'an warned the group to stay inside the black shield, then left to explore the deeper cavern for materials to forge treasures for his children.
• Two Peak Great Emperor Realm men competed to descend one step at a time at ten li deep, then sensed someone approaching rapidly.
• Lu Qing'an flashed between the two men and continued deeper, while they were left stunned and had to fend off the flames.

Lu Qing'an descended into the Heavenfall Demon Cavern in search of Heavenfall Divine Metal, while cultivators who saw him wondered if he was the missing Eternal Night Demon Emperor. He passed a young formation master at a depth of twenty-five li and continued toward the cavern's deepest reaches.

• Two peak great emperor realm cultivators saw a figure plunge through the cavern and speculated that he might be the Eternal Night Demon Emperor.
• Lu Qing'an reached his old mark at a depth of twenty li and continued downward, hoping to find enough Heavenfall Divine Metal to forge treasures for his daughters.
• Lu Qing'an noticed a stranger using formations to withstand the cavern's flames and passed by without stopping.
• A red-haired young woman practicing formations at twenty-five li saw Lu Qing'an fly past and was shocked that he had so little protection.

Lu Qing'an descended to the bottom of the Heavenfall Demon Cavern, collecting large amounts of Heavenfall Divine Metal and discovering a living power sealed inside a colossal piece. The mysterious life-form attacked him, but he brushed aside its presence and moved closer to investigate.

• Lu Qing'an passed the depth he had reached as the Eternal Night Demon Emperor and began descending slowly through the cavern.
• He collected pieces of Heavenfall Divine Metal, including enough for several weapons and armor, while enduring the cavern's increasingly dangerous power.
• When the cavern narrowed and his strength proved insufficient, Lu Qing'an raised it to three times its original level and continued downward.
• At the cavern's bottom, Lu Qing'an found a carriage-sized piece of Heavenfall Divine Metal containing a pulsing, silver-gray power that seemed alive.
• The life-form released a terrifying presence at Lu Qing'an, but he dispersed it and pressed closer to investigate.

Lu Qing'an subdued a powerful energy life-form inside the heavenfall divine metal and stored it away before returning toward the children. At the same time, a red-haired woman discovered Xu Yunyi’s Innate Array Physique and hurried over, hoping to make her a disciple.

• Lu Qing'an quieted the energy being with the Immortal-Slaying Black Flame, removed it from the heavenfall divine metal, and forced it into a box despite its dislike of the container.
• Lu Qing'an stored the heavenfall divine metal and flew up after searching the cavern for anything else worth taking.
• The red-haired woman’s state of mind was unsettled, so she left her cultivation depth and spotted the black shield of light near three li below the surface.
• Lu Zixuan, Sun Minzi, Lu Miaomiao, and Xu Yunyi continued tempering themselves inside the shield, while Xu Yunyi practiced formations and revealed her Innate Array Physique.
• The red-haired woman recognized Xu Yunyi’s physique, decided she could inherit her legacy, and flew toward the group, making all four wary.

Luo Danhong discovered Xu Yunyi’s Innate Array Physique and offered to make her a disciple, but Xu Yunyi refused to decide until her brother-in-law returned. When Luo Danhong touched Lu Qing'an’s black shield, its pressure destroyed nine of her ten defensive arrays.

• Luo Danhong sensed that Xu Yunyi’s cultivation carried the Spiritual Qi of the Immortal Ruins and confronted her outside the black shield.
• Luo Danhong offered to pass her array inheritance to Xu Yunyi if she crippled her cultivation and started over with Demon Domain techniques.
• Lu Zixuan urged Xu Yunyi to wait for her father, and Xu Yunyi told Luo Danhong she would decide after her brother-in-law returned.
• Luo Danhong learned that Lu Qing'an had made the black shield and reached out to examine it.
• The shield unleashed destructive pressure that shattered nine of Luo Danhong’s ten defensive arrays.

Luo Danhong tested Lu Qing'an's black shield and learned that its defensive power could shatter her formations. When Lu Qing'an returned, he questioned her about the shield and asked Xu Yunyi what Luo Danhong had said.

• Luo Danhong watched as the shield's energy destroyed nine of her defensive formations, leaving her and Xu Yunyi stunned.
• Xu Yunyi urged Luo Danhong to wait for Lu Qing'an, and Lu Miaomiao spotted him appearing silently behind the formation master.
• Lu Qing'an startled Luo Danhong when he spoke from behind her, and she spun around with her formations raised.
• Lu Qing'an questioned Luo Danhong about touching his Demonic Qi Shield, and she said she had only been curious.
• Lu Qing'an checked with Lu Zixuan, then asked Xu Yunyi what Luo Danhong had said to them.

Xu Yunyi considered becoming Luo Danhong's disciple to learn the array path, while Lu Qing'an agreed to help and warned Luo Danhong against harming her. Luo Danhong revealed she was Huang Hao's senior sister and recognized Lu Qing'an as the Eternal Night Demon Emperor before he brought everyone back to Demon Descent City.

• Xu Yunyi told Lu Qing'an that Luo Danhong wanted to take her as a disciple, and Lu Qing'an asked whether she wanted to stay in the Demon Domain to study arrays.
• Xu Yunyi said she would think about staying, and Lu Qing'an warned Luo Danhong that she would face his wrath if she harbored ill intentions toward her.
• Luo Danhong explained that Huang Hao was her junior brother and that she had surpassed him as an array master after spending thirty thousand years in seclusion.
• Lu Qing'an asked Luo Danhong to summon Huang Hao to Demon Descent City, and she realized Lu Qing'an was the Eternal Night Demon Emperor.
• Luo Danhong said Huang Hao was in seclusion recovering from an array battle injury, so Lu Qing'an brought her and the others back to Demon Descent City through a void passage.

Wang Duanshan arrived at the courtyard after Xue Tianfei confirmed that Lu Qing'an had returned, but he resisted helping He Hong build an artifact-refining room. As Wang Duanshan answered He Hong's artifact-refining questions, Lu Qing'an's presence appeared in the sky, confirming his return.

• Wang Duanshan arrived and demanded proof that the Eternal Night Demon Emperor had returned; Xue Tianfei confirmed it and told him Lu Qing'an wanted help building He Hong an artifact-refining room.
• Wang Duanshan refused to start work, and he and Xue Tianfei nearly fought before Xiao Qingyi and He Hong mediated.
• He Hong asked Wang Duanshan about artifact refining, and Wang Duanshan answered several questions, becoming impressed by He Hong's unusual problems.
• He Hong's final question left Wang Duanshan unable to answer until Xiao Qingyi announced that Lu Qing'an had returned.
• Wang Duanshan sensed Lu Qing'an's powerful presence and realized the others had told him the truth.

Lu Qing'an returned with his companions and reunited with Wang Duanshan, who doted on Lu Qing'an's daughters and agreed to help refine treasures. When Lu Qing'an revealed a huge mass of heavenfall divine metal, Wang Duanshan was so shocked he fell to the ground.

• Lu Qing'an returned to the courtyard with Lu Miaomiao, Lu Zixuan, Luo Danhong, Sun Minzi, and He Hong, and greeted Wang Duanshan.
• Lu Miaomiao and Lu Zixuan called Wang Duanshan Grandpa Wang, and he offered them tenth-grade supreme-quality weapons as gifts.
• At Lu Qing'an's suggestion, the girls each took an extra weapon and gave one to Xu Yunyi and Sun Minzi.
• Lu Qing'an introduced He Hong as his good friend and asked Wang Duanshan to refine treasures and teach He Hong artifact-refining techniques.
• Lu Qing'an brought out a huge mass of heavenfall divine metal, and Wang Duanshan exclaimed in shock and fell to the ground.

Lu Qing'an showed the Demon Domain experts a massive piece of heavenfall divine metal and an unknown being from the deepest part of the Heavenfall Demon Cavern, then arranged for an artifact-refining chamber to be built. Xu Yunyi considered staying long-term, and her sister Xu Qingying was stunned when Xu Yunyi told her.

• Wang Duanshan and He Hong eagerly accepted Lu Qing'an's heavenfall divine metal to design and forge weapons and armor.
• Lu Qing'an revealed a mysterious mass of energy, and Luo Danhong suggested it might be an unhatched living creature or demonic beast.
• Lu Qing'an told the group he had found the metal and the mysterious being in the deepest part of the Heavenfall Demon Cavern, but several experts doubted he could have reached it.
• Lu Qing'an assigned everyone to help build an artifact-refining chamber and offered to help Xu Yunyi convert her cultivation if she chose to stay.
• Xue Tianfei questioned Luo Danhong about her background while Xu Yunyi contacted her sister Xu Qingying to discuss staying long-term.
• Xu Qingying froze in surprise when Xu Yunyi told her she was thinking of staying instead of returning.

Xu Yunyi told Xu Qingying she wanted to remain in the Demon Domain after awakening the Innate Array Physique and receiving a chance to study under a powerful array master. Xu Qingying remained concerned that Lu Qing'an had misled her, so she asked Xu Yunyi to reconsider and agreed they would speak again the next day.

• Xu Yunyi told Xu Qingying she wanted to stay in the Demon Domain because she had awakened the Innate Array Physique and could study the Array Dao under a powerful master.
• Xu Qingying and Xu Xuanyu questioned whether Xu Yunyi had been tricked, but Xu Yunyi defended Lu Qing'an and said he could convert her cultivation to the Demon Domain system.
• Xu Yunyi withheld Lu Qing'an's identity as the Eternal Night Demon Emperor, not wanting to shake Xu Qingying's Dao heart.
• Xu Qingying urged Xu Yunyi to think carefully before deciding and postponed their discussion until the next day.

Xu Yunyi agreed to return to the Immortal Ruins so her sister could verify that her decision to stay with Lu Qing'an was freely made. After Xu Yunyi came back that night, Xu Qingying and Xu Xuanyu prepared to investigate whether she had been manipulated.

• Xu Yunyi told Lu Qing'an that she would keep the Eternal Night Demon Emperor identity secret from Xu Qingying for now, and she warned He Hong that Xu Qingying might contact him.
• He Hong learned that Lu Qing'an was the Eternal Night Demon Emperor, while Xu Qingying contacted He Hong and confirmed that Lu Qing'an could help Xu Yunyi convert her cultivation.
• Xu Qingying said Xu Yunyi would have to return if she wanted her to believe the decision was genuine, so Lu Qing'an took Xu Yunyi to the realm barrier and she crossed back into the Immortal Ruins.
• Xu Yunyi returned to Xu Qingying's hall that night and found Xu Qingying, Xu Xuanyu, Lin Qingxue, and two Peak Great Emperor Realm experts waiting for her.

Xu Yunyi returned to say goodbye to Xu Qingying and Xu Xuanyu, insisting that she trusted Lu Qing'an and wanted to return to the Demon Domain to study arrays. After her divine soul examination found nothing wrong, Lin Qingxue secretly instructed Fellow Daoist Jia to fabricate a result and claim Xu Yunyi had been affected by a secret art, leaving her family poised to stop her from returning.

• Xu Yunyi revealed her Innate Array Physique and said she had decided to return to the Demon Domain, despite Xu Qingying and Xu Xuanyu urging her to stay.
• Xu Xuanyu questioned Lu Qing'an's ability to convert cultivation, and Xu Yunyi defended him, then argued with Lin Qingxue about her choice.
• Lin Qingxue introduced Zhang Huairen as a potential array master, but Xu Yunyi said Luo Danhong was more skilled, and Zhang demonstrated his strongest array without changing her mind.
• Lin Qingxue asked Fellow Daoist Jia to examine Xu Yunyi's divine soul; he privately reported that it was normal.
• Lin Qingxue instructed Fellow Daoist Jia to lie, and he told Xu Qingying that someone had used a secret art on Xu Yunyi's divine soul.
• Xu Yunyi protested the false accusation as Lin Qingxue urged Xu Qingying not to let her return to the Demon Domain.

Xu Yunyi fought her sister and Lin Qingxue when they tried to keep her in the Immortal Ruins, convinced they were plotting against her. She escaped with a teleportation array and sent Lu Qing'an a message asking him to meet her at the realm barrier, while Lin Qingxue ordered Zhang Huairen to pursue her.

• Xu Qingying and Lin Qingxue insisted that Xu Yunyi remain in the Immortal Ruins because they believed a demonic secret technique had affected her.

• Xu Yunyi pressed the sword to her neck and threatened to die, forcing Xu Qingying and Xu Xuanyu to hold back.
• Xu Yunyi set up a teleportation array, warned her siblings not to trust Lin Qingxue, and activated it to escape.
• Xu Yunyi sent Lu Qing'an a message asking him to meet her at the realm barrier, and Lin Qingxue told Zhang Huairen to break the array and chase her.

Xu Qingying confronted Lin Qingxue over her attempt to manipulate Xu Yunyi, who crossed into the Demon Domain and chose to stay with Lu Qing'an. Xu Yunyi began her path as Luo Danhong’s disciple, while Lu Qing'an warned Luo Danhong to teach her only array techniques.

• Xu Qingying stopped Lin Qingxue and Zhang Huairen from pursuing Xu Yunyi, then accused Lin Qingxue of treating her sister like a tool and demanded she consult her before meddling with her family again.
• Lin Qingxue admitted she had been wrong but warned Xu Qingying that Lu Qing'an might fail to convert Xu Yunyi’s cultivation.
• Xu Yunyi reached the Demon Domain boundary, reunited with Lu Qing'an, and confirmed she would stay there and have him convert her cultivation.
• Lu Qing'an brought Xu Yunyi to his courtyard, where Lu Miaomiao welcomed her and Lu Zixuan asked whether she was staying for good.
• Xu Yunyi knelt to become Luo Danhong’s disciple and vowed to become the strongest array master.
• Lu Qing'an warned Luo Danhong to teach Xu Yunyi only arrays and used his overwhelming presence to ensure Luo Danhong understood his concern.
