For a time, the Foundation Establishment cultivators gathered in Yang Heaven Hall were in a noisy uproar, with constant discussions, completely lacking the demeanor of experts. Zhang Ling glanced at the token thrown out by the Sect Leader a few times, then stood aside silently. At this moment, the mood of the others was not very good, and the Sect Leader didn't say anything about it, also looking at the Demon Elimination Order in the air with a solemn expression. After half a cup of tea, the cultivators in the hall quieted down, but some people were still whispering to each other, some with their lips moving slightly, but without making a sound, instead using the art of sound transmission. Clearly, they hadn't stopped discussing. Of course, most of the cultivators were still looking at the Sect Leader, waiting for him to speak. Sect Leader Wang Chengfeng remained silent for a while, then with a wave of his hand, he pinched the Demon Elimination Order in his hand, rubbed it a few times, coughed, and said, "Fellow brothers, I think most of you are clear about the weight of the Demon Elimination Order. This item was personally delivered by a Golden Core elder from Misty Cloud Immortal City three days ago." "After discussion among the elders in the sect, this matter is not false." "As for why it was advanced by a hundred years, it is likely that something happened in the Continuous Cloud Mountains, and that group of Other-world Demon clansmen appeared." "Although our Nine Great Sects are located relatively far back, we cannot stand idly by. The sect has decided to send some fellow disciples to provide support, but fellow brothers don't need to worry too much. The Other-world Demons have not yet launched a large-scale invasion, there are only some signs of it." Hearing the Sect Leader's words, the reactions of those present varied. Some had gloomy faces, some were expressionless and very calm, and of course, most showed expressions of unease.

Zhang Ling lowered his head, thinking about the information about the Other-world Demon race that he had seen in the sect's records. The Other-world Demon race is a group of alien races living on the other side of the Black Cloud Desert. It's not accurate to call them alien races, they were once humans too. Because there were no Other-world Demons in ancient times, but after the Ancient Demon Realm invaded this world, it brought in a strong demonic aura, wanting to transform this world into a demonic aura environment suitable for the Ancient Demons to live in. The influx of a large amount of demonic aura also caused the spiritual energy of this world to mutate. However, after the bloody battle of the ancient cultivators, the Ancient Demons who crossed the border were defeated, and the space通道 connecting this world was either destroyed or sealed. Although the Ancient Demons left, the large amount of demonic aura they brought did not disappear, but existed in this world. This demonic aura is suitable for the Ancient Demons to survive, but it is greatly harmful to the creatures of this world. Being eroded by demonic aura for a long time, cultivators are better off, although their bodies are affected by spiritual power. But some special methods can still be used to avoid it. The most typical example is the cultivators who practice demonic cultivation methods. They are less affected by these demonic auras and can even greatly increase their own strength. After all, the cultivation methods practiced by demonic cultivators now are mostly related to the Ancient Demons. But cultivators are definitely a minority, and there are a large number of mortals without spiritual roots in the human race. Once these people come into contact with demonic aura, they either die directly or are assimilated, becoming bloodthirsty and ferocious like wild beasts. Although mortals are looked down upon by cultivators, they are definitely the foundation of the human race, and ancient cultivators would naturally not allow demonic aura to run rampant. Therefore, they sealed these demonic auras, but some cultivators and mortals had already been corrupted by the demonic aura. For these people, the human race naturally regarded them as aliens and did not treat them as humans. They carried out a massacre. No one would choose death over life, and once the heart of resistance is born, it is difficult to suppress. The corrupted humans naturally would not sit still and wait for death. They also had high-level cultivators, some of whom were even cultivators who had resisted the Ancient Demons before. Facing the massacre, they formed an alliance and formed a force. These high-level cultivators also had the strength to reach the Transformation God stage. A great battle immediately swept across the entire Northern Origin cultivation world again. Because the number of human cultivators was several times greater than that of the Other-world Demons, the battlefield formed a one-sided situation. In the end, most of the Other-world Demons were killed, and the remaining people were forced into a desert. When the ancient cultivators were about to slaughter all of these corrupted human races, the high-level cultivators among the Other-world Demons, at the cost of self-destruction, destroyed a place where demonic aura was sealed. A large amount of demonic aura reappeared, directly covering nearly half of the Northern Origin cultivation world.

After that, the Other-world Demons claimed that if they were driven to extinction again, they would perish together. They would desperately unlock all the demonic aura seals, and even use secret methods to connect to the Ancient Demon Realm and summon the group of Ancient Demons from another world to descend again. With this concern, the two sides began to negotiate. In the end, the Other-world Demon race occupied a region in the westernmost part of the Northern Origin cultivation world. They later called themselves Other-world Demons and drew a line with the human race. The two sides have never had a large-scale war again, but friction is inevitable. After all, many people on both sides had died at the hands of the other before. Therefore, the human race also built twelve immortal cities, connected in a line, forming a defensive line like a great wall, monitoring this group of Other-world Demons. After that, the Other-world Demons would attack the human race every once in a while. This has continued to this day. Several times, the Other-world Demons broke through the defense line and even destroyed several immortal cities, invading wantonly. However, they would often plunder and retreat outside the defense line. But this has also formed a long-term hatred, and the human race will also send cultivators to fight this situation. Generally, a large-scale invasion by the Other-world Demons only occurs once every three or four hundred years. Zhang Ling saw in the classics that the last time the Other-world Demons invaded was only about two hundred years ago. It is far from the time of invasion, but the invasion of the Other-world Demons is not fixed. Unexpectedly, they caught up with it, which is not a good thing. The current invasion of the Other-world Demons is not the ancient times. But every invasion of the Other-world Demons will also kill and injure a large number of cultivators. The Qi Refining and Foundation Establishment cultivators are the most dead, and the Golden Core cultivators cannot guarantee their own safety, and many people will die. Even the Nascent Soul stage ancestor-level experts will have some casualties. These pressures are not borne by the twelve immortal cities alone, and are naturally distributed to the major sects in the Northern Origin cultivation world. As for why the Hao Yuan Sect received the Demon Elimination Order. This is to talk about the current division of power in the Northern Origin cultivation world. In addition to the power of the Other-world Demons, it is roughly divided into four forces. The righteous path, the demonic path, the twelve immortal cities, and the surrounding countries near the boundless sea and other forces. Leaving aside the others, the Nine Sects such as the Hao Yuan Sect are not among these forces, belonging to the neutral forces. However, the three countries controlled by the Nine Sects are located near the twelve immortal cities, in the northwest of the Northern Origin cultivation world. Therefore, they are also within the scope of the Other-world Demon invasion. Although generally speaking, the Other-world Demons cannot invade their forces. But with the twelve immortal cities pressing down on them, whenever the Other-world Demons invade, they will issue a Demon Elimination Order to the sects in these neutral countries, inviting them to resist together. As for the righteous and demonic forces, they also participated in resisting the Other-world Demons at first, but after the evolution of time, they now rarely participate. Resisting the Other-world Demons has fallen on the heads of the twelve immortal cities and the nearby neutral forces.
