In the north of Ciyun Prefecture, a place bordering Dongtianfu in the north, the terrain is steep, the climate is cold, the poor mountains and bad waters are everywhere, and the spirit beasts are entrenched in the middle. The environment there is the most treacherous in Ciyun Prefecture, and it is also the place where the survival pressure of the human race is the greatest. Therefore, as long as it is not a last resort, none of the immortal cultivators in Ciyun Prefecture go there to develop, and the human race there is often attacked by spirit beasts, and beast tides also occur from time to time, although the situation is not as bad as that of Kuimen Prefecture, but in the eyes of the human race in Ciyun Prefecture, there is not much difference between the two places.

Knowing this, Su Aotian decided to go there with Lian Qiongyu to cultivate, after all, a too comfortable environment is not a good thing for cultivation, it will only wear down people's will. Of course, Lian Qiongyu would not object to such a suggestion, although she has not suffered as much as Su Aotian over the years, but compared to ordinary people, she has not been able to catch up in several lifetimes.

The idea must have been that the two of them set off immediately, and after several years, they came to a small city in the north of Ciyun Prefecture close to the border, Black Cloud City. In the center of Ciyun Prefecture, it is impossible to use such a name, and these small cities in remote places, in addition to picking up these disdainful names, the actual situation is also consistent with the name, compared to the center, the life here can only be described as black clouds full of sky, and there is no day all year round.

The defense of Black Cloud City was extremely strict, and Su Aotian and the others wanted to enter the city, but they were strictly interrogated by the city guards. The main purpose of these examinations is to verify whether the two are truly Terrans, after all, the other races in the spirit world are no different from Terrans in appearance. As for the origin of the two, they did not deliberately ask. Because everyone knows that everyone who comes here to beg for a living has unspeakable reasons, and they won't tell the truth if they ask. Here, only strength is important, and the cultivation of the two of them is no longer considered weak, and although the city guards are meticulous in their investigation, they are polite to the two of them.

As soon as he entered Black Cloud City, Su Aotian found that the relationship between people here was tense, there were not many people walking around the street, and almost all of them had straight faces, each going their own way, ignoring others, and almost no one walked together. The immortal cultivators in the city have uneven cultivation, and the gap is huge, there are people who have just entered the Yuan Realm, and there are also those who are at the peak of the Immortal Realm. Su Aotian also noticed that in the center of Black Cloud City, in a grand courtyard that looked like a city lord's mansion, three extremely powerful auras were revealed, which had broken through the realm of the Immortal Realm, at least at the level of the sub-saint. Such a dilapidated small city is strong enough to crush Fuzhou City. In addition to the immortal cultivators, there are also a large number of martial artists in the city, and this situation is also similar to the cities of Kuimen Prefecture, but it is very different from the mainstream cities of Ciyun Prefecture. In the heart of Ciyun Prefecture, the warriors lived in villages around the city, and they were not eligible to enter the city.

I think it's because the human race here has a lot of pressure to survive, so they have to hold together, and the warriors have also been able to live in the city. And many people are very wary because they have secrets that cannot be detected, and they rarely communicate with each other, and even hate to have to speak, so they seem to have very tense interpersonal relationships.

However, such an environment is just right for Su Aotian's mind, the two of them didn't come here to look for relatives and friends, and no one came to disturb him. Black Cloud City has prepared different residences for different levels of immortal cultivators, and the two of them have been assigned to an independent courtyard with the cultivation of the Immortal Realm, and after the city guards brought them, they briefly explained a few words of the city rules, which are nothing more than no trouble, no private fights, and some rules that are common in all cities. It's just that here, two more items have been added separately, one is that when encountering the beast tide attacking the city, you must obey the arrangement and resist with all your might; the other is that you are not allowed to go out of the city without permission, if you have something to go out, you must apply in advance, and after getting approval, you must form a group to act together, and individuals are not allowed to leave the city alone.

These two special regulations have almost no effect on the two of them, their purpose is to cultivate and improve, and the beast tide is regarded as one of the means of improvement; However, Su Aotian wanted to wait for a while, and he still had to go outside the city for a trip or two, generally between the poor mountains and bad waters, there are often hidden opportunities, such as the hidden space found in Kuimen Prefecture; if he happened to meet one, it would not be a trip to this Black Cloud City in vain.

Perhaps it was a coincidence that the two of them had only been in Black Cloud City for a few months before they encountered a siege by the beast tide. They were naturally very familiar with such things, and after receiving the summons, the two of them quickly set off and came to the corresponding area for defense according to the instructions.

There was a black pressure in front of him that pressed the endless spirit beast, which made the local immortal cultivators in Black Cloud City explode when they saw it, and they didn't think so in the eyes of Su Aotian and the others. The scale of such a beast tide can only be regarded as nothing compared to the beast tide in Kuimen Prefecture, but the level of the spirit beast is much higher, the rhinoceros horned deer is a half-herbivore and half-carnivorous spirit beast, which cannot be seen here, and the goods like the earth dragon act as the heavy task of charging into battle, dozens of huge and huge King Kong giant apes that are as heavy as mountains when they run, and they also roar forward, followed by three-legged golden beasts, and some four-legged and long-horned monsters, which are also spirit beasts such as rhinos.

Different environments have created different spirit beasts, in Kuimen Prefecture, the spirit beast of the level of the three-legged golden beast is the most pinnacle existence, and even some newly civilized spirit clans are inferior in strength; and in Ciyun Prefecture, there are many more powerful spirit beasts than it, behind it, a huge black snake that winds and swims, like a moving hill moving forward, two eyes like lanterns, and two bulges on its head, representing the blood of a dragon on its body. If these two bulges can grow horns, it means that this black snake has the possibility of turning into a Jiao!

In this kind of battle, the warriors are already powerless, their task is to hide behind the city wall, ready to repair the hole in the city wall at any time, even if it is to fill it with their lives, it must be filled;

Although the spirit beast is terrifying, the power of the human race is also unprecedentedly strong, Su Aotian, a cultivator who has just entered the fairy realm, can only be regarded as the backbone, and the high-end combat power is not counting the three immortal cultivators at the sub-saint level, there are more than ten people in the fourth and fifth orders of the fairy realm, after fighting fiercely for more than a month, the monsters of the King Kong giant ape and the rhinoceros were all killed, the black giant snake was seriously injured and fled, the large and small spirit beasts left the corpses all over the ground and scattered, and the beast tide was repelled without danger.

With such a strong strength as a guarantee, Su Aotian doesn't need to show his might, although he is very eager to fight that giant snake, and he will definitely be able to improve from the battle, but people here are unpredictable, and there is really no need to expose his strength. You only need to meditate here for a while, and when you have achieved something, you will leave, so it is necessary to keep a low profile.

Cultivation has no years, thousands of years have passed in a flash, and the cultivation of the two people can be regarded as going hand in hand, but they have broken through one layer and have just reached the second stage of the fairyland. According to this momentum, 350,000 years will not be able to break through to the sub-saint, and 180,000 years is not easy to say!

During this period, Su Aotian saw that there was not much progress in blind penance, and he also went out of the city several times to meet opportunities in the wild, but the ethereal thing of chance is so strange, every time you are unintentional, you suddenly encounter it, and if you have the idea of looking for opportunities, it will definitely end up in vain. Su Aotian's luck has always been bad, and this time is no exception, and he has searched for it several times in vain.

The pressure of the beast tide makes the cultivation atmosphere in Black Cloud City very strong, which is also very helpful for Su Aotian and the others, the effect of cultivation here is indeed better than that of places like Qingyun City and Baiyun City, but for Su Aotian, he feels that it is still too slow.

But Lian Qiongyu is by his side, which cannot be said to be a burden, and it does hinder his cultivation. If there is no Lian Qiongyu, he can go alone to find a spirit beast like the black monster snake to sharpen himself and improve quickly, and now that the rest of them are separated, a Lian Qiongyu who finally found it, he is bound to maintain her thoughtfulness, if she has a mistake, she will not be able to explain when she sees Luo Wentian in the future.

Therefore, in order to practice Qiongyu, he can't take risks easily, let alone lose her, the vast spiritual world is extremely vast, and if he loses a person and wants to find it, it is countless times more difficult than looking for a needle in a haystack. This kind of mind can't be revealed to Lian Qiongyu, and she can't make her feel that she is a burden.

In a contradictory and anxious mood, Su Aotian tried his best to restrain his inner impulses and practiced diligently day and night. He could feel that Lian Qiongyu was like him, anxious about the slow improvement of his cultivation, so he had to persuade Lian Qiongyu in turn, remembering to be impatient and rash, and he must know that if he wants to be fast, he will not reach it.

And he didn't know at all, the crisis was approaching step by step, for the past two thousand years, some people have been thinking about him and not forgetting him, searching for his whereabouts all over the world, and gradually got clues, looking all the way in the direction of Black Cloud City!

A dark night that was no different from ordinary days, the piercing sound of alarm woke Su Aotian from his quiet meditation, and the shouts of "Beast Tide Attack" spread throughout the city, and the human race rushed to the battlefield one after another, and Su Aotian and Lian Qiongyu also rushed out of the house.

Su Aotian's divine sense instinctively probed in the direction of the beast tide, and suddenly he was full of excitement, his face changed drastically, and an expression of disbelief and surprise appeared on his face. Lian Qiongyu was already planning to step out of the door, and when he saw his reaction, he couldn't help but be surprised. Because in her impression, she had almost never seen Su Aotian have such a gaffe!

Without waiting for her to ask, Su Aotian had already said in a deep voice: "Black Cloud City can't hold it, tell everyone to flee for their lives!"
