This is what happened in the extremely distant past.
How long ago was it? Because there was a gap in history, it was no longer possible to detect it.
People now only know that in order to prevent the illusion demons from coming from the Chaos Demon Cave to the present world, humans established Tianfeng City.
In other words, when the Chaos Demon Cave appeared, Tianfeng City had not yet been established.
At that time, the present world seemed to have just begun to connect with the Spirit Demon Prison, and humans and illusion demons also formally clashed on this land and started a racial war.
As the largest entrance to the spiritual demon prison at that time, the Chaos Demon Cave brought to the human world is undoubtedly the greatest and most deadly.
In order to resist the illusion demons who came from the Chaos Demon Cave to the present world, the people among humans who had just obtained extraordinary power fought bravely without fear of death.
The final result was that the Chaos Demon Cave was sealed by forbidden art. In order to guard the Chaos Demon Cave, humans also established the base city of Tianfeng City in the human area closest to the Chaos Demon Cave, allowing Tianfeng City to gradually gain a transcendent status and become a holy place for humans.
"At that time, the seal of the Chaos Demon Cave was still intact. The illusion of the Spirit Demon Prison could not invade through the entrance of the Spirit Demon Prison, the Spirit Demon Prison, which made Tianfeng City enter a period of rapid development, with many strong men and family forces appearing in a burst of explosions."
In front of everyone in the tent, Xu Xiayan began to tell this secret.
"At that time, Tianfeng City was still a feudal country, and the royal family was also built. As the left arm and right arm of the royal family, our royal family has been escorting the royal family. While protecting the royal family, Tianfeng City can allow humans who have experienced the dark period before the Chaos Demon Cave were sealed."
It is precisely because of the special status of the Wang family that the Wang family’s library actually contains many ancient books that other clans do not have, and many historical records from a long time ago.
Xu Xiayan had learned about the history of that period, so she told everyone without any confusion.
"If we can continue to continue like that, then humans will inevitably grow and grow in a very short time. Tianfeng City can also have enough power to guard the Chaos Demon Cave while casting the extra power inland, assist other base cities, and resist and expel the illusion demons on the land."
In that case, perhaps, sooner or later, the illusion demon may be driven out of the land where humans survive, either they can only return to the Spirit Demon Prison or enter the ocean area, otherwise they will only be attacked.
It’s a pity that the good times won’t last long.
"In the Spirit Demon Prison, a terrifying existence noticed the present world and the entrance to the Chaos Demon Cave, and launched an invasion of the present world."
That is the King of the Spirit Demon Prison who once caused the earthly creatures to be miserable and turned into hell, an existence that stood at the peak of the illusion demon race, has evolved to the end - "Horror Seed".
Such existence is already above billions of creatures.
Such existence can already make seven-star professions far beyond the reach.
Even in the Spirit Demon Prison, there will definitely be no more than three such existences.
But it was this terrifying existence that launched the most terrifying invasion in history in this world.
"It tore open the seal of the Chaos Demon Cave with its right hand containing endless power, and swallowed the earth with its left hand that can kill all lives in an instant, and finally broke the Tianfeng City, which was guarding the front line."
"Countless heroes and heroes gathered together, and countless strong men gathered to resist the "king". However, no matter whether they were directly attacked by advanced spiritual techniques or pierced by sub-artifact-level alchemy weapons, it never stopped ravaging. With a heart that can continuously repair its body and restore its wounds, it crushed the entire human race with one person's strength."
"In the end, humans could only fight with their backs, gathered the strongest group of heroes, stopped the king of the Spirit Demon Prison on the border of the mainland, and made great sacrifices. They used forbidden techniques to cut off the "king"'s arms and dug out the "king's heart, so that it no longer has an invincible body and no longer has endless power, and then they successfully sealed it."
Xu Xiayan said in a deep voice and looked around at everyone present.
"In this battle alone, the royal family completely declined, and humans also lost many strong people. Although Tianfeng City was rebuilt, the seal of the Chaos Demon Cave had defects because it was torn apart once."
This is why there will be gaps in the seal of the Chaos Demon Cave. Over the years, many illusion demons have still come to the present world through the Chaos Demon Cave.
Even if the seal barely maintained, blocking the path of those truly powerful beings, making the terror species unable to reappear, and even the nightmare species could not come from the other side of the Chaos Demon Cave, and the Spirit Demon Prison could no longer invade in large quantities, but large-scale invasions were not possible, and a small-scale invasion like boiled frogs was always there.
Over the years, the illusion demons have been coming from the other side of the Chaos Demon Cave, causing the number of illusion demons to increase and decrease, barely maintaining a balance. Various wonders have appeared one after another around Tianfeng City under the influence of the Chaos Demon Cave, forming one after another.
Now, so many illusion demons who have come to this world have evolved, some have evolved into dangerous species, some have evolved into nightmare species, each occupying one wonderland and enclosing land as kings.
Although Tianfeng City has been trying every means to maintain the seal of the Chaos Demon Cave, the defects of the seal are still irreparable, and the gap still exists.
"Some people in humans also propose whether to apply a seal again, but if the forbidden-level seal is used, they must sacrifice many powerful people standing at the peak of human beings."
"Even if it is willing to sacrifice, the top human leaders will not agree."
"Unless you have to encounter a real crisis, you will lose so many strong people just to repair some seal gaps, which is not worth the loss."
To be honest, each of those strong men standing at the peak of human beings is the confidence used by humans to fight against the illusion demons. A true trump card, losing one can cause damage to the entire human race, let alone more than one.
If the seal is completely broken and there is no way, then you have to bear the pain of accepting sacrifice.
But the seal has not been completely broken, but there is only a part of the gap, so it is not worth the human strong men doing this.
"So, the senior executives of Tianfeng City have to find a way to repair the seal of the Chaos Demon Cave every once in a while, not to completely repair the seal, but to only ask not to increase the gaps, and not to let more illusion demons, the strongest illusion demons come to the present world."
“This period is about once every sixty years.”
"Every sixty years, Tianfeng City has to repair the seal, that is, maintain the seal of the Chaos Demon Cave."
Xu Xiayan explained the reason here.
"Next year will be the sixty years of maintenance next time."
In view of this, Tianfeng City has been preparing for this year.
"If you want to repair the seal, you not only need assistance from the elders of the Warlock Guild, but also provide technical support, but also need many special extraordinary items to assist."
"Some of these extraordinary items are alchemy props, and some are heavenly and earthly treasures."
"Alchemy props are easy to deal with. This is not the first time Tianfeng City has carried out seal maintenance work, and all the props used in the past have been left."
But some special treasures are more difficult to deal with.
"These treasures are all extremely precious and rare things."
"Even in a resource treasure house like Tianfeng City, there are some that do not even have inventory. They need to be searched again, and at the least they need to find their substitutes."
"For this reason, Tianfeng City has actually prepared a lot of commissions, some entrusted to some big families, some entrusted to some big forces, and some entrusted to some big teams."
Xu Xiayan's words are already very clear and easy to understand.
"In other words, Captain Xu's "Xiari Zhuyan" received such a commission, right?"
Qiao Liang looked at Xu Xiayan and said so.
"That's right." Xu Xiayan smiled slightly and said, "This is the origin of our SS-level mission, and it is also what we will do next."
According to Xu Xiayan, among the commissions issued by Tianfeng City, some are only B-level, some are S-level, and only a few are able to reach SS-level.
"Summer Chasing Smoke" takes one of these few SS-level tasks.
"There is an extremely rare and precious treasure among the extraordinary items needed to repair the seal."
As he said that, Xu Xiayan stood up and operated on the screen built in the deepest part of the tent a few times, allowing the screen to show an image.
It is a three-dimensional appearance diagram of a treasure.
"Wire?"
Zhu Qian murmured in surprise.
Yes.
The treasures that appear on the screen are very thin silk threads.
The silk thread is like a dream, like a light without substance, floating gently like flowing water.
Looking at the golden streaming silk threads on the screen, everyone started to talk.
"What a beautiful treasure..."
"What line is this?"
"It looks like the sunlight condenses into thin threads, looking very nice."
"Just relying on this appearance, even if it is not a treasure, countless people are willing to spend a lot of money to buy it to appreciate and collect it, right?"
Everyone was just admiring.
Even Chi Qian couldn't help but take a few more glances, with a faint light flowing in her eyes, which made Su Ming feel a little amused and crying.
Xu Xiayan seemed to have expected everyone's reaction, and smiled and began to introduce.
"The Golden Silk Dream Demon Line, an extremely rare treasure of heaven and earth, looks like a stream of tiny silk threads condensed from sunlight, but it is only nurtured in an extremely dark place where the magic is extremely sufficient and there is no light seen throughout the year."
Xu Xiayan operated the screen again, causing introductory texts to appear around the treasure image.
"This kind of golden silk dream demon thread not only has strict requirements on the environment of birth, but it will not be born in ten years. It will not be considered as a form after a hundred years have passed, and this treasure will be considered as taking shape."
In a nutshell, this is a treasure that will only be born once every one hundred years. It is conceivable how precious and rare it is.
Perhaps, even compared with Dragon Demon Swallow and Purple Snow Pulse, this Golden Wire Dream Demon Line is a priceless treasure of the same level.
"Its function is also very simple. It can be used to refine battle suits, alchemy armor, and also to refine some alchemy weapons. For example, the young master of Zhang's love bow, and the bow string of the bow is said to be made of a linear treasure similar to the golden silk dream demon line, but it is not as rare as the golden silk dream demon line."
"In addition, some top-quality alchemy potions that are even divine, may also be used as the main material."
"It has a wide range of functions and is therefore of high value. It is a precious alchemy material that countless alchemists cannot obtain."
Xu Xiayan's explanation is quite detailed and easy to understand, making people immediately understand the preciousness and speciality of this golden silk dream demon thread.
certainly...
"For Tianfeng City, this golden silk dream demon thread has an important role, which is to cooperate with the sorcerers of the Warlock Guild to spiritually repair the gaps in the Chaos Demon Cave seal, fill some of the gaps, or prevent it from expanding."
After saying this, Xu Xiayan looked around at everyone present again.
"For this reason, I will organize everyone to enter the polar night maze together and come to this tenth floor."
What is the implication of it? It is clear at a glance.
"So that's it." Chi Qian whispered: "Is that golden silk dream demon line on the tenth floor of this extreme night maze?"
"Yes." Xu Xiayan nodded heavily and said, "The environment on the tenth level of this extreme night maze is one of the few places in this world that can meet the birth of the Golden Silk Dream Demon Line."
This is the result obtained by relevant departments in Tianfeng City after rigorous and complex calculations.
They believed that on the tenth floor of this extreme night maze, the possibility of the golden silk dream demon line appeared is very high.
That's why they handed this SS-level commission to "Summer Zhuyan", allowing "Summer Zhuyan" A-level team with the strength of the S-level team to enter the extreme night maze and look for the Golden Silk Dream Demon Line.
But...
"If you just come to this tenth floor to find treasures, you don't need to hire so many powerful teams to help you "Summer Smoke Chasing"?"
"I think so too."
Qiao Zhi and Zhu Yun, the second in charge of the A-level team, both expressed their ideas.
They are right.
Just looking for a treasure, Xu Xiayan's team is fully competent, so why bother hiring so much team to help?
Even if you need manpower, you won’t find teams like “Jinlong Jade Pavilion” and “Iron Rose”.
Xu Xiayan gathers combat power like this and does not use it to fight, which is simply a waste of resources.
The same is true.
"If things were that simple, that would be great."
Xu Xiayan sighed.
"Didn't you notice that this tenth floor is different from the floor in front of you, and you haven't even seen a illusion demon?"
Hearing this, everyone was stunned.
"really..."
