Both sides were racing against time to regain their strength, so much so that Xu Qing had no time to see Concubine Haolingyin and Moon Demon Tianchan. This matter is strange. Xu Qing always felt that there were many doubts in it. He did not want to continue fighting with the Xuanlin Demon General. After all, the opponent was the clone of a demon king, so he asked Yao Ji, who presided over the enchantment array, to tell Xuanlin that The siege of the Hanjing Cave has been resolved, but Xuan Lin has not left just yet. Shiyuan Cave is the gateway to Qingshi Cave Mansion. It is located in front of Qingshi Dongting. The enchantment formation arranged in Shiyuan Cave originated from the Ghost King Sect. Due to the lack of magical weapons, this formation has no killing power and is mainly used to trap opponents and delay them. time. Xuan Lin has the strength of a demon general after all. Facing the ecstasy formation presided over by the three ghost servants, it is not difficult to break the formation and escape, but it just won't leave. Xu Qing guessed that it had seen through the mystery of the Bluestone Cave and wanted to practice here and restore its strength to its peak. However, this idea was wrong. If he were Xuan Lin, he would first choose to retreat and return to the Nanling Mountains. He met up with his old subordinates in the Hanjing Cave, and then led the others to kill him. There must be a reason why Xuan Lin did not choose this simplest countermeasure. In the past few days, Xu Qing has been staying in the Black Pond Secret Mansion, using the Xuanwu Seal in his hand to continuously refine the tens of thousands of Xuanming ghost power contained in it, as well as the surrounding thick Yin Qi to restore his cultivation. Following the suggestion of Concubine Haoling Yin, he has refined the Yin Ghost Flag into his own natal ghost weapon. If he puts this flag up, he can use the Yin Ghost Flag's Yin Absorption Formation to absorb Yin Qi from ten miles around. Help yourself to practice. With the natal ghost weapon in hand, Xu Qing finally understood that if a ghost cultivator wanted to forge a ghost elixir and be promoted to a ghost general, the natal ghost weapon must be simultaneously promoted to the magic weapon level. The old ghost Xuanfeng took the risk to refine the Black Wood Order into a natal ghost weapon. Precisely because the Black Wood Order is a magical weapon. As for his Yin Ghost Banner, it is not difficult to upgrade it to a magic weapon. All he needs to do is kill more human ghosts and monsters and use their souls to enhance the foundation of the Yin Ghost Banner. Either kill tens of thousands of people or kill a few. Hundreds of monks with profound cultivation. After a few days of meditation, Xu Qing gradually restored his cultivation to its original state, because he could use the Thirteen Flags Ghost to absorb yin energy and refine ghost power around him, thus helping him to quickly restore his cultivation. When the ghost power in his body broke through the previous limit and approached 80,000, he opened his eyes, took back the Yin Ghost Flag and the Thirteen Flag Ghost, turned into a ray of Yin light and fled through the water. After all, this world relies on strength. A phoenix that lands on the ground is not as good as a chicken. So what if Xuan Lin is the demon king's clone? Since it insists on occupying Xu Qing's cave, Xu Qing can only kill the demon to suppress it. As seen in the clouds that day, even if the demon king comes to kill in anger, there will always be those who are guarding the Longyan Mountains. The ancestor of Xuanmen blocked the way. The Demon Commander is equal to the Great Monk of the Spiritual Palace, and the Demon King is equal to the Spiritual Ancestor. Those old monsters sitting in the Longyan Mountains, if they are not at the level of the ancestors, how can they stop the Demon King of Southern Xinjiang? Xu Qing flew over and entered the bluestone cave. Three ghost servants were sitting on three sides of the green pool. The pool was thirty-three feet deep and had a thousand-year-old Yin acupoint at the bottom. Together with the surrounding traction formation and Yin acupoint formation as the center, it formed a A huge Nine Palace Spirit Gathering Formation can gather the spiritual energy and Yin energy of the entire Black Pool Ridge. Because too much Taiyin energy has gathered from the water veins of the Black Pond, the water color of the Qingtan is dark and gloomy, and there are even millions of strands of Yin Qi sinking at the bottom of the pond. The three ghost servants rely on this Qingtan and Jiugong to gather together. The great spiritual formation will confront the Xuan Scale Demon. Seeing Xu Qing, the three ghost servants stood up to see him. Xu Qing was silent, sitting on the array plate, controlling the ecstasy array in Shitu Cave with them. The three ghost servants sat down again. Yao Ji had the highest level of formation cultivation, and she had always been the main one to deal with Xuan Lin. Seeing Xu Qing sitting down to take charge of the formation, Yao Ji knew that this matter must determine the winner and the loser, and said: "Master, this demon general has many methods. Even when he is surrounded by our large formation, he can forcibly absorb the formation." The Yin Qi in Shitu Cave itself has no great killing power. If you really want to defeat it, you may need corpse servants to fight. " Xu Qing has already considered the matter very clearly in the past few days. He replied: "Then just kill it." Xu Qing's decision shocked the three ghost servants secretly. After all, the Black Scale Demon General was the incarnation of a demon king. Even the Qingxia Palace did not dare to do it. To kill it is just to imprison it with a formation. Xu Qing did not explain too much. Instead, he used the help of the local Nine Palaces Spirit Gathering Formation to take out the four Yin Talismans and remelt them. He integrated them into the various understandings of the Corpse Demon Dao in the past six months and re-melted the four Yin Talismans. Sealed in the divine court of the four black iron corpses to help them improve their spirits. Four hundred years ago, the Xu family was attacked by the Blackscale Demon General in the Nanling Mine. The head of the Nanfu Family and a disciple who was protecting the law at that time died in the attack by the demons. Fortunately, the whole body was left intact. With the help of the demonic energy in the cave, Nian turned into the nature of the corpse demon, causing the two corpses to?Become a zombie. Especially the head of the Nanfu family, who was known as the first among the sixteen family heads in Wuyan City at the time. He had practiced Tianyin Kung Fu to the peak of the late Qi refining stage at the age of thirty, and was three points more powerful than Xu Yulin today. He was expected to become the first patriarch of the Xu family in Lone Peak Castle who was born in the Nanfu. He had only one last step left, but he died outside the Hanjing Cave in the Nanling Mine. He had a strong obsession and possessed iron after transforming into a corpse. The combat power of the corpse. Four hundred years of accumulation, how powerful. Xu Qing had already sealed the corpse demon souls of the two black iron corpses. After careful study, he found that the two snake monsters had left a demon master curse seal in their souls, which could suppress their cultivation. This was exactly the reason. This is the reason why the two Black Iron Corpses have been unable to be promoted to Corpse Generals. There are only two ways to break this curse seal, one is to forcibly erase it with external force, and the other is to kill the original seal owner. When the two snake demons agreed to transfer them to Xu Qing, they had already dissipated the curse seals, leaving only some residues, leaving Xu Qing with an opportunity to study this strange magic seal. After the battle at Yunyan Mountain, Xu Qing had already refined two yin talismans for the two new black iron corpses. At that time, he was eager to absorb the essence, blood and remnant souls, and the refining was a bit crude. He also suppressed it a little and did not let it go. The corpse demon soul and the Yin Talisman were completely integrated, and the remaining curse mark of the Demon Lord was not completely erased. In the past six months, Xu Qing's understanding and control of the corpse demon servant path and the evil sealing technique have gradually improved to a higher level. Taking this opportunity, he took out all the corpse demon talismans of the four black iron corpses and re-established them. Refining. When he refined it again, each Yin Talisman had two more complete layers of sealing patterns, exuding a cyan-colored brilliance. The Yin Talisman contained more techniques and martial arts, protecting the corpse demon soul and protecting it. Control also becomes stronger. The Corpse Demon Yin Talisman of Demon Corpse Achan and Demon Corpse Ahu still returned to their original positions, and the remaining two Yin talismans had to be completely integrated with the Corpse Demon Yuanshen. Taking advantage of this opportunity, Xu Qing carefully studied the remaining yin symbols in the Yuanshen. Use your own evil-sealing magic to break the demon lord's curse seal. He took out the two demon pills that he had obtained from killing Xu Tianao and the beautiful woman in black robes, and helped the corpse demon soul to swallow the demonic energy, fuse the demon pills, and further enhance the level of the soul. Xuan Tiezhi, who was born as the head of the Xifu family, had a stronger corpse demon soul, and was suppressed by the two big snake demons for the longest time. He couldn't wait to snatch the black snake demon pill. Although the demon energy in this demon pill was suppressed by the twelve The Flying Snake Gu absorbed more than half of it, but there was still a part of the power of transforming into a dragon. I also wanted to get the other Black Iron Corpse, but I couldn't compete with it so I settled for the next best thing and got Xu Tianao's Yin Demon Wolf Demon elixir. Xu Qing left a rubbing copy of the "Demon King's Sacred Fetus Sutra" in their Yin Talisman, and personally helped them refine the demon elixir and integrate it into the corpse. The two demon pills have been refined, and the remaining power is not as good as the complete demon pill. The strength of the two new black iron corpses is close to that of the corpse generals. After four hundred years of hard work and accumulation, they can easily defeat the demon pills. The elixir is melted and refined, but the demon elixir is incomplete. There will definitely be many shortcomings in the process of practicing the "Demon Emperor Divine Fetus Sutra" in the future. At this time, Xu Qing already has four black iron corpses in his hands, which is equivalent to having four strong men in the refining stage, and they are all of a very strange lineage of demon corpses. Especially the two newly acquired ones, their strength is closer to that of the Corpse General. If they can be given a few months to concentrate on using the Mysterious Corpse Demonic Art to refine their corpse power, their promotion to the Corpse General will be just around the corner. Xu Qing was always very patient. He spent three days helping the two new black iron corpses in the bluestone cave to forge the foundation of the "Demon King's Sacred Fetus Sutra" and melt the demon elixir, and then each played a green The light melted into their Yuan Shen Yin Talisman, naming them Yin Xuan and Yin Kui. As he had more and more corpse servants, he uniformly set up a dharma title of "Yin". The four corpse servants were Yin Chan, Yin Hu, Yin Xuan, and Yin Kui, followed closely by the ones who were taken from the Blue Blood Cave. The obtained blood corpse, because of its outstanding talent, is now only one step away from the realm of the black iron corpse. There were seven iron corpses under the blood corpse, including a poison corpse made from a disciple of the Poison King Valley. However, two of them were chopped off by Yan Chiling's sword, and it would take some time for them to fully recover. Xu Qing established a rule in the Corpse Demon Court of Qingshi Cave Mansion. Those who are promoted to Black Iron Corpse can be given a dharma title. Before that, they will all be under the control of the ghost servant Rosen. In the past few days, the three ghost servants have continued to confront Xuan Lin, but they still have not tested the depth of Xuan Lin. After all, the other party is the clone of a demon king. Xu Qing does not dare to be careless and kill all four corpse servants. They were mobilized in Qingtan to prepare for war. In addition, Bai Zhi has already taken precautions under the Qingtan, Xu Qing will still use the entire power of the Qingshi Cave to decide the outcome with his opponent, and will never underestimate his opponent. When the four corpse servants and the white snake demon servant appeared, the three Rosen ghosts recognized each other and were convinced that Xu Qing was really going to kill a demon king clone this time. They couldn't help but feel uneasy and worried about the demon king's revenge.
